Olive Oil Salad Dressing: The Basic Ratio and Five Variations
An olive oil salad dressing recipe is really a ratio with a few seasonings attached: three parts extra virgin olive oil to one part vinegar, salt dissolved in the vinegar first, and something to help the two hold together. Learn that once and you never need a bottled dressing again. What most recipes leave out is why the ratio sometimes tastes wrong. Vinegars differ in strength, so the same three-to-one can be sharp with one bottle and flat with another. Below is our own base vinaigrette, written from scratch for this article with metric, US and weight measures side by side, a table for scaling it from one salad to a week's jar, a simple way to adjust for the vinegar you actually have, and five variations, from honey mustard to a dark, sweet-sharp dressing made with date syrup.

The Short Answer
- The basic olive oil salad dressing ratio is 3 parts extra virgin olive oil to 1 part vinegar by volume, for example 90ml (6 tbsp) oil to 30ml (2 tbsp) vinegar.
- Our base recipe adds 1 tsp Dijon mustard, ¼ tsp fine salt and a pinch of black pepper, with ½ tsp honey if you like it rounder. It makes about 125ml (just over ½ cup), enough for four to six side salads.
- The ratio is really about acid strength. Most cider and white vinegars are sold at about 5% acidity; milder vinegars such as rice vinegar need a little more vinegar to taste as bright.
- Dissolve the salt in the vinegar before the oil goes in, and shake everything in a sealed jar for 20–30 seconds. Mustard helps the dressing hold together for longer.
- Five easy variations: honey mustard, Italian-style herb, pomegranate molasses, ginger and rice vinegar, and a date-syrup dressing in the style of balsamic.
- A plain vinaigrette keeps in the fridge for about a week. Versions with fresh garlic or fresh ginger should be refrigerated and used within 4 days.
- Sidr & Stone's olive oil is a single-estate, cold-pressed, unfiltered extra virgin oil from our own farm on the plains outside Marrakech, Morocco, sold in 500ml dark glass.
Olive Oil Salad Dressing Recipe (Metric, US and Weight)
This is the everyday vinaigrette: balanced, lightly tangy and thick enough to cling to leaves. It takes five minutes and one clean jam jar with a lid. We use apple cider vinegar as the default because it is mild, fruity and in most cupboards; any vinegar of around 5% acidity works the same way.
| Ingredient | Metric | US | Weight |
|---|---|---|---|
| Extra virgin olive oil | 90ml | 6 tbsp | about 82g |
| Apple cider vinegar (about 5% acidity) | 30ml | 2 tbsp | about 30g |
| Dijon mustard | 5ml | 1 tsp | about 5g |
| Fine salt | ¼ tsp | ¼ tsp | about 1.5g |
| Freshly ground black pepper | A pinch | A pinch | — |
| Honey (optional) | ½ tsp | ½ tsp | about 3.5g |
Method
- Season the vinegar. Put the vinegar and salt in the jar and swirl until the salt has dissolved. Salt does not dissolve in oil, so if you add it last it stays gritty.
- Add the mustard, pepper and honey. Stir them into the vinegar so the mustard is evenly spread before the oil arrives.
- Add the oil and shake. Pour in all the oil, close the lid tightly and shake hard for 20–30 seconds, until the dressing turns cloudy and slightly thick. If you prefer a bowl, whisk the oil in a thin stream instead.
- Taste on a leaf. Dip a salad leaf rather than tasting from a spoon; a dressing that seems sharp on its own is often right on a salad. Too sharp: add a tablespoon of oil. Too flat: a teaspoon of vinegar or a pinch of salt.
- Dress just before serving. Start with about half and add more until the leaves look glossed rather than wet.
The weights are there for anyone who measures with a scale: olive oil is lighter than water, so 90ml weighs a little over 80g. If you would rather not measure at all, mark the jar: fill it with vinegar to one line, then oil to a line three times as high, and the jar becomes your measuring cup.
The 3:1 Ratio, Scaled From One Salad to a Week's Jar
For most salads, use 3 parts extra virgin olive oil to 1 part vinegar. One "part" can be a teaspoon, a tablespoon or a jar's worth; the proportion is what matters. The table below scales the base recipe so you can make exactly what you need.
| Batch | Olive oil | Vinegar | Dijon mustard | Salt | Makes |
|---|---|---|---|---|---|
| One large salad | 3 tbsp (45ml) | 1 tbsp (15ml) | ½ tsp | a pinch | about 60ml (¼ cup) |
| Four to six side salads | 6 tbsp (90ml) | 2 tbsp (30ml) | 1 tsp | ¼ tsp | about 125ml (½ cup) |
| A week's jar | ¾ cup (180ml) | ¼ cup (60ml) | 2 tsp | ½ tsp | about 250ml (1 cup) |
Then move the ratio to suit what is in the bowl. Soft lettuce, avocado and other delicate leaves are happier at 4:1, with the oil leading. Bitter leaves, cabbage, grains, beans and lentils can take 2:1, because they soak dressing up and mute its sharpness. Mustard and honey both make a sharper ratio taste softer, which is why a honey mustard dressing can sit closer to 2:1 without tasting aggressive.
Which Vinegar? Why Acidity Changes the Ratio
The three-to-one rule quietly assumes a vinegar of about 5% acidity. In the United States, FDA guidance says vinegar should contain at least 4 grams of acetic acid per 100ml, and Penn State Extension notes that most white and cider vinegars are sold at 5%, "but not all". Some labels give strength in "grain" instead: 50 grain is 5%. So the honest way to think about the ratio is as a balance of oil against acid, not oil against liquid.
| Vinegar | Typical strength | Starting ratio (oil : vinegar) | Character in a dressing |
|---|---|---|---|
| Apple cider vinegar | About 5% | 3 : 1 | Mild and fruity; the all-rounder |
| Distilled white vinegar | About 5% (check the label) | 3 : 1, or 4 : 1 | Clean but harsh; best softened with honey or mustard |
| Malt vinegar | Check the label | 3 : 1 | Robust and malty; good with potato and cabbage salads |
| Rice vinegar (unseasoned) | Often around 4–5% | 2.5 : 1 | Soft and gentle; suits ginger and sesame |
The arithmetic is simple. If your vinegar is milder than 5%, use a little more of it; if it is stronger, use a little less, or add a spoonful of water to the vinegar. Rice vinegar at about 4% needs roughly 2½ tablespoons to deliver the same sourness as 2 tablespoons of a 5% cider vinegar. One caution: "seasoned" rice vinegar already contains sugar and salt, so if that is what you have, cut the honey and salt in the recipe.
Lemon juice works too, and has its own guide: our lemon olive oil dressing covers the lemon ratio and five lemon-based variations. For balsamic, and the difference between traditional and supermarket balsamic, see our guide to olive oil and balsamic vinegar.
Jar or Whisk: Getting the Dressing to Hold
Oil and vinegar do not mix on their own. Shaking or whisking breaks the oil into tiny droplets suspended in the vinegar, which is why the dressing turns cloudy and slightly thick, and left to stand the droplets rejoin and the oil rises to the top. That is normal; a split dressing tastes exactly the same once shaken again.
- Use mustard. A teaspoon of Dijon in the base recipe is the simplest way to keep the dressing creamy for longer.
- Shake in a jar. It is faster than whisking, gives a thicker result and doubles as storage.
- Whisk slowly if using a bowl. A thin stream of oil makes smaller droplets than tipping it in all at once.
- Re-shake before every use. Even a well-made vinaigrette separates in the fridge.
Five Olive Oil Salad Dressing Variations
Each of these starts from the base recipe (90ml / 6 tbsp extra virgin olive oil and 30ml / 2 tbsp vinegar) and changes one or two things. They are our own starting points, so taste on a leaf and adjust.
1. Honey mustard dressing
Keep the cider vinegar. Replace the Dijon with 1 tsp Dijon plus 2 tsp wholegrain mustard, and raise the honey to 2 tsp. Because honey and mustard soften the acid, you can go to 2.5:1 (add an extra 1 tbsp vinegar) and it will still taste mellow. Good with crisp leaves, shredded cabbage, apple and walnut salads, and roasted carrots.
2. Italian-style herb dressing
Leave out the honey. Add ½ tsp dried oregano and ½ tsp dried basil, rubbed between your fingers, a pinch of chilli flakes, and 1 small garlic clove, finely grated into the vinegar and left for 10 minutes before the oil goes in. Shake well. It suits tomatoes, cucumber, bean salads and pasta salads; because it contains fresh garlic, keep it in the fridge and use it within 4 days.
3. Pomegranate molasses dressing
Pomegranate molasses is pomegranate juice boiled down to a thick, sweet-sour syrup, used widely in Middle Eastern cooking. Use 15ml (1 tbsp) cider vinegar and 15ml (1 tbsp) pomegranate molasses in place of the 30ml vinegar, leave out the mustard and honey, and add ½ tsp ground sumac. It is a natural fit for fattoush-style salads of cucumber, tomato, radish, herbs and toasted flatbread, and for grain salads finished with pomegranate seeds.
4. Ginger and rice vinegar dressing
Use 37ml (2½ tbsp) unseasoned rice vinegar instead of the cider vinegar, since it is milder. Add 1 tsp finely grated fresh ginger and 1 tsp honey, and leave out the mustard. Stir in 1 tsp toasted sesame seeds just before serving, and, if you like the flavour, ½ tsp toasted sesame oil. Use it on shredded cabbage and carrot slaws, cucumber, noodle salads and leafy greens. Fresh ginger is treated like garlic here: refrigerate and use within 4 days.
5. Date syrup "balsamic-style" dressing
Keep the cider vinegar and Dijon, and replace the honey with 2 tsp date syrup. The result is dark, glossy and sweet-sharp, with something of the character of a balsamic dressing, and it is useful if you have no balsamic in the house or prefer a vinegar that is not made from wine. It is very good on bitter leaves, roasted squash and beetroot, and salads with dates or figs.
For the classic lemon-based versions, including a Greek-style ladolemono and a lemon tahini dressing, see our lemon olive oil dressing guide rather than repeating them here.
Which Olive Oil to Use in Salad Dressing
Use extra virgin olive oil. In a vinaigrette the oil is three quarters of the jar and is eaten raw, so its flavour is the dressing's flavour. Extra virgin oil is mechanically pressed and never refined, so it keeps the fruity, grassy, bitter and peppery notes of the olives; refined and "light" olive oils are processed to be neutral and add fat without much taste.
A medium, fruity extra virgin oil is the safest choice for an everyday dressing. A robust, peppery oil suits bitter leaves, beans and grains; a delicate one suits soft lettuce and fruit. Our article on olive oil for salad matches oil styles to particular leaves, and our guide to choosing a quality olive oil covers what to look for on the label: the extra virgin grade, a harvest or best-before date, dark glass or a tin, and a named origin.
Freshness matters more here than anywhere else in the kitchen. An oil that has gone stale smells of crayons, putty or old nuts, and vinegar will not cover it up.
How Long Does Homemade Olive Oil Dressing Last?
A plain vinaigrette of oil, vinegar, mustard, salt, pepper and honey keeps in a sealed jar in the fridge for about a week. The flavour is best in the first few days.
Fresh garlic, fresh ginger and fresh herbs change that. Oregon State University Extension advises that fresh garlic or herbs held in oil should be refrigerated and used within 4 days, because these low-acid foods can carry Clostridium botulinum and oil shuts out the air. We apply the same rule to the garlic and ginger variations above, and we would not rely on the vinegar in a home dressing to make them safe for longer.
When the jar comes out of the fridge, the oil may look cloudy or partly solid. That is normal for olive oil in the cold and reverses at room temperature: take the jar out 15–20 minutes before you need it, then shake. Do not leave garlic or ginger versions out on the worktop for hours to soften.
Is Olive Oil Salad Dressing Healthy?
It is a short ingredient list you control: oil, vinegar, salt, mustard and, if you choose, a little honey. Compared with many bottled dressings, there are no thickeners or preservatives, and you decide how much salt and sugar goes in. It is not a low-calorie food, though; almost all of its calories come from the oil, so use enough to gloss the leaves rather than drown them.
The fat is not wasted on a salad. In a small crossover study published in the American Journal of Clinical Nutrition in 2004, Brown and colleagues gave seven adults the same salad of spinach, romaine, cherry tomatoes and carrots with dressings containing 0, 6 or 28g of oil; absorption of carotenoids such as beta-carotene and lycopene was negligible with the fat-free dressing and rose with each step up in fat. The dressing used canola oil rather than olive oil, and seven people is a very small sample, so read it as a sensible reason not to fear dressing a salad, not as proof of a health effect. Extra virgin olive oil also carries polyphenols that refined oils largely lack; our article on olive oil polyphenols sets out what the research does and does not show.
Two objections come up often. "Three parts oil is too much fat": a two-tablespoon serving of the base dressing contains about a tablespoon and a half of oil, spread across a whole bowl of vegetables, and you can always move to 2:1. "Why not just buy a bottle?": you can, but a homemade jar costs a few minutes, keeps for a week, and lets you choose the oil, which is the ingredient that matters most.
Why Sidr & Stone
A vinaigrette is only as good as the oil in it, and the oil is the part of this recipe we can speak for. Sidr & Stone's extra virgin olive oil comes from one place, our own farm on the plains outside Marrakech, and we control every step from tree to bottle.
- Single-estate: Sidr & Stone's olive oil comes from our own family-owned farm near Marrakech, Morocco, with no blending across origins.
- Rain-fed: the trees are not irrigated; they take what the season gives.
- Organically grown: no synthetic fertilisers, pesticides or herbicides are used (not yet certified; certification is in progress).
- Single harvest: each batch is small and limited, picked when the fruit is ready, and once it is gone, it is gone until the next harvest.
- Cold-pressed within hours of harvest: to protect flavour, aroma and polyphenols.
- Unfiltered extra virgin: minimally processed, so a little natural sediment at the bottom of the bottle is normal.
- 100% natural: a single ingredient, olive oil, with nothing added.
- Dark glass with a gold label: 500ml bottles that protect the oil from light.
- 10% of profits to charity: a Sidr & Stone commitment across every product.
- Fulfilment in the UK, EU and US.
We will not tell you ours is the best olive oil for salad dressing; that depends on your palate and what is in the bowl. What we will say is that it is single-estate Moroccan, rain-fed, organically grown and cold-pressed within hours of harvest, and that in a dressing where the oil is three quarters of the jar, those details are what you taste.
Frequently Asked Questions
What is a simple olive oil salad dressing recipe?
Dissolve ¼ tsp salt in 2 tbsp (30ml) apple cider vinegar, add 1 tsp Dijon mustard and a pinch of pepper, then add 6 tbsp (90ml) extra virgin olive oil and shake in a sealed jar for 20–30 seconds. Taste on a leaf and adjust.
What is the ratio of olive oil to vinegar for salad dressing?
Three parts olive oil to one part vinegar is the standard, assuming a vinegar of about 5% acidity. Use 4:1 for delicate leaves, 2:1 for bitter leaves, grains and pulses, and a little more vinegar if yours is milder, such as rice vinegar.
Can I make olive oil dressing with apple cider vinegar?
Yes. Apple cider vinegar is our default for this recipe: most is sold at about 5% acidity, which suits the classic 3:1 ratio, and its mild fruitiness works with almost any salad.
Why does my olive oil dressing separate?
Oil and vinegar do not mix, so the droplets made by shaking or whisking gradually rejoin. It is harmless; shake it again. A teaspoon of Dijon mustard keeps it together for longer.
Is Sidr & Stone's olive oil good for salad dressings?
Yes. It is a single-estate, cold-pressed, unfiltered extra virgin olive oil, which is the grade that brings real olive flavour to a raw dressing. Dressings are where an oil's freshness and character show most clearly.
How long does homemade vinaigrette last in the fridge?
A plain oil, vinegar and mustard dressing keeps for about a week in a sealed jar. If it contains fresh garlic, fresh ginger or fresh herbs, refrigerate it and use it within 4 days.
Where can I buy single-estate extra virgin olive oil?
Our Cold-Pressed Single-Estate Extra Virgin Olive Oil - Marrakech (500ml) is available directly from the Sidr & Stone website, with fulfilment in the UK, EU and US.
Is olive oil a medicine?
No. Olive oil is a food, not a medicine. It has a long traditional history — including being honoured in the Prophetic Sunnah — and a substantial body of modern research, particularly around polyphenols, cardiovascular health, and the Mediterranean diet pattern. It can be a worthwhile part of a healthy routine, but it does not cure diseases and is not a substitute for medical care. Be cautious of any olive oil marketed with specific disease-cure claims.
Final Thoughts
A good olive oil salad dressing is a habit more than a recipe. Salt the vinegar, add three times as much oil, add a little mustard, shake, taste on a leaf. Once that is second nature, adjusting is easy: more vinegar for bitter leaves and grains, less for soft lettuce, a little extra when the vinegar is mild. The five variations follow from the same jar.
The one thing technique cannot fix is the oil. It makes up most of the dressing and is eaten raw, so use an extra virgin oil you would happily eat on bread. Our Cold-Pressed Single-Estate Extra Virgin Olive Oil - Marrakech (500ml), single-estate, rain-fed and cold-pressed within hours of harvest, is available to pre-order now, with fulfilment in the UK, EU and US.
Our extra virgin olive oil is grown organically on our own single-estate farm on the plains outside Marrakech: we control every step from tree to bottle, and no synthetic pesticides, herbicides or fertilisers are used. It is not yet certified organic — certification is in progress, and we will publish it as soon as it comes through.
