Olive Oil Grilled Cheese: Why It Crisps Better Than Butter
Olive oil grilled cheese is a sandwich cooked in olive oil instead of butter, and done properly it comes out with a crisper, more evenly golden crust than the butter version. The reason is simple: olive oil is pure fat, while butter is only about 80% fat, with the rest mostly water plus milk solids that brown quickly and can scorch before the cheese inside has melted. Below is our own olive oil grilled cheese recipe, written from scratch for this article, in grams and US measures, with the two habits that make it work: brushing the oil onto the bread rather than pouring it into the pan, and cooking low with a lid on for the first side. After the recipe, we cover which cheese and bread melt and crisp best, which olive oil to use, and an honest look at where butter still has a case.

The Short Answer
- Yes, olive oil works for grilled cheese: brushed onto the outside of the bread, it fries the surface into an even, golden, crackly crust.
- It crisps more evenly than butter because it contains no water to steam the bread and no milk solids to brown in patches or burn; US law defines butter as at least 80% milk fat, so up to a fifth of it is something other than fat.
- Our recipe uses 2 slices of sturdy bread, 60g (2oz) of grated cheese and 1 tablespoon (15ml) of extra virgin olive oil, cooked over medium-low heat for about 7–8 minutes in total.
- Brush the oil onto the bread, edge to edge, rather than pouring it into the pan, so the crust browns evenly and the bread does not soak up oil and go greasy.
- Grated cheese, a lid for the first side and patience at medium-low heat let the middle melt before the outside goes too dark.
- A mild or medium-fruity extra virgin olive oil gives a savoury, faintly peppery crust; finish with a few drops of raw oil and flaky salt.
- Sidr & Stone's olive oil is a single-estate, cold-pressed, unfiltered extra virgin olive oil from our own farm on the plains outside Marrakech, Morocco, sold in 500ml dark glass.
Olive Oil Grilled Cheese Recipe: Ingredients
This makes one sandwich. Scale it by the slice: every extra sandwich needs another two slices of bread, 60g of cheese and a tablespoon of oil. Weighing the cheese is worth doing once, so you learn what 60g looks like in your own grater.
| Ingredient | Metric | US | Notes |
|---|---|---|---|
| Sturdy bread: sourdough, country loaf or a good sandwich loaf | 2 slices, about 1.5cm thick (roughly 100g) | 2 slices, about ½in thick | Day-old bread crisps better than very fresh |
| Good melting cheese, coarsely grated (for example mature cheddar with a little mozzarella or Gruyère) | 60g | 2oz (about ⅔ cup loosely packed) | Grated cheese melts faster and more evenly than slices |
| Extra virgin olive oil, for brushing | 1 tbsp (15ml) | 1 tbsp | About 1½ tsp per outer face |
| To finish: extra virgin olive oil and flaky sea salt | a few drops, a pinch | a few drops, a pinch | Optional: black pepper or a pinch of dried oregano |
Equipment: a heavy frying pan or skillet about 20–25cm (8–10in) across, cast iron or non-stick, a lid that fits it (or a large upturned bowl or baking tray), a pastry brush and a thin, wide spatula.
Method: How to Make Grilled Cheese With Olive Oil, Step by Step
- Let the cheese lose its chill. Grate the cheese and leave it on the board for about 10 minutes while you get everything else ready. Fridge-cold cheese is the main reason a grilled cheese ends up dark outside and solid inside.
- Oil the bread, not the pan. Lay the two slices on a board and brush one face of each with the olive oil, right to the edges and crusts, about 1½ teaspoons per slice. The oiled faces become the outside of the sandwich.
- Build the sandwich. Turn one slice oil side down, pile the grated cheese onto it, keeping a few millimetres clear of the edges, and top with the second slice, oil side up. Press gently so it holds together.
- Heat the pan gently. Put the dry pan over medium-low heat for about 2 minutes. It is ready when a drop of water flicked onto it sizzles softly rather than spitting and vanishing at once.
- Cook the first side covered. Lay the sandwich in the pan, cover with the lid and cook for 3–4 minutes, until the underside is an even deep gold and the cheese at the edges has started to soften. The lid traps heat around the sandwich so the cheese melts on the same timetable as the crust browns.
- Flip and cook uncovered. Turn it with the spatula, press lightly once, and cook the second side without the lid for another 3–4 minutes, until golden and crisp and the cheese is fully melted. Leaving the lid off lets the steam escape, so the first side stays crisp.
- Finish and rest. Move the sandwich to a board, add a few drops of raw olive oil and a pinch of flaky salt to the top, and let it sit for one minute before cutting. The cheese firms slightly, so it stretches rather than running out.
If your hob runs hot, drop the heat a notch and add a minute to each side; the crust should take on colour steadily, never in the first 60 seconds. If the crust is browning well but the cheese is still firm, put the lid back on for a minute off the heat. The same low-and-steady approach applies to frying eggs in olive oil, which pair well with this sandwich.
Why Olive Oil Crisps Better Than Butter
A grilled cheese crust is fried bread, and frying is a job for fat. Olive oil is essentially 100% fat, so everything you brush on the bread goes into browning and crisping it. Butter is a mixture: in the US it must contain not less than 80% milk fat by weight (21 U.S.C. § 321a), and the rest is mostly water with a small amount of milk protein and sugar. That small non-fat share is what changes the result.
- Water steams before it fries. As butter melts, its water boils off into the bread's surface. Until it has gone, the crust is being steamed as much as fried, which is why butter crusts can be soft in places.
- Milk solids brown in patches. The protein and sugar in butter brown fast and settle unevenly, giving a speckled crust with darker spots, and at too high a heat they scorch before the cheese has melted.
- Oil coats evenly. Brushed edge to edge, olive oil spreads into a thin, even film over the whole face, so the crust browns at the same rate from crust to centre.
- Brushing beats spreading. Cold butter tears soft bread and leaves bare patches; a brush of oil reaches every crevice of an open-crumbed sourdough.
What butter does have is flavour: those same milk solids give the nutty, toasty taste people associate with a classic grilled cheese. Olive oil swaps that for a cleaner, more savoury crust with a faint fruitiness. Our article on olive oil vs butter covers the wider comparison, including nutrition.
The objection: "Butter still won the taste test, didn't it?"
Not quite, and it is worth being precise. In The Kitchn's grilled cheese method test (Cory Fernandez, April 2022), olive oil scored 7/10 against 6.5/10 for butter alone; the tester found the browning great and the bread nicely crisp, but the sandwich a little one-dimensional. The top scores went to combinations: olive oil with butter 9/10, and butter with mayonnaise 10/10. So olive oil edged plain butter overall, and the strongest flavour came from mixing fats. If you miss the butter taste, a teaspoon of butter melted into the oil before brushing is a fair compromise; our recipe stays butter-free because that is what most people searching for it want.
Which Cheese and Bread Work Best With Olive Oil?
Olive oil changes the crust, not the filling, so the usual grilled cheese rules still apply. The cheese needs to melt smoothly, and the bread needs to be sturdy enough to fry without going limp.
| Cheese | How it melts | Best use |
|---|---|---|
| Mature (sharp) cheddar | Melts well when grated; can turn slightly oily if very aged | The flavour base; mix with a stretchier cheese |
| Low-moisture mozzarella | Very smooth and stretchy, mild flavour | Up to half the mix for the cheese pull |
| Gruyère, Comté or Emmental | Melts evenly, nutty and rich | Excellent alone or with cheddar |
| Fontina or provolone | Soft, creamy melt | An Italian-style sandwich with basil |
| Feta, halloumi, paneer or hard Parmesan-style cheese | Soften but do not flow | Small amounts for flavour, not as the main cheese |
For bread, sourdough and country loaves are the natural partners for olive oil: their open crumb takes the brushed oil into its holes and fries into a crackly, uneven crust. A soft white sandwich loaf works too and gives the classic flat, even gold, but cut it a little thicker and use a slightly lighter brush of oil, since soft crumb absorbs more. Avoid very fresh, very soft bread, which squashes and steams.
If you keep halal or vegetarian, check the cheese label: many cheeses are made with animal rennet, while others use microbial or vegetable rennet and are labelled accordingly. That choice is about the filling; olive oil itself is a single-ingredient plant fat.
Which Olive Oil Should You Use for Grilled Cheese?
Use extra virgin olive oil. At medium-low heat the pan never gets near the temperatures that worry people, and a good extra virgin oil copes well with ordinary frying, as our guide to olive oil for frying explains in detail. The questions are taste and quantity.
- Mild or medium-fruity extra virgin: the easiest choice. It gives a savoury, golden crust with a gentle olive note that sits well with cheddar and Gruyère.
- Robust, peppery extra virgin: very good with strong cheeses, tomato and herbs; with mild cheese and white bread its bitterness can stand out, so brush a little less.
- Refined or "light" olive oil: crisps the bread just as well but tastes of almost nothing. It is a texture swap, not a flavour one.
- Garlic or herb olive oils: lovely here, but check the base oil is extra virgin, and do not make your own fresh-garlic oil to keep at room temperature; it carries a food-safety risk.
Freshness matters more than price. Rancid olive oil smells of crayons or putty, and frying the bread will make that more obvious, not less. Our guide to choosing a quality olive oil covers what to check on the bottle: the grade, a harvest or best-before date, dark glass or a tin, and a named origin.
The objection: "Doesn't extra virgin olive oil burn in a frying pan?"
Not at grilled cheese heat. This recipe cooks over medium-low heat for 7–8 minutes, and most of the oil is soaking into bread rather than sitting in a hot pool. Extra virgin olive oil holds up well in everyday pan cooking, which our article on olive oil at high heat sets out with the evidence. If your oil is smoking, the problem is the heat setting, and the bread will be burning too.
Variations: Air Fryer, Oven, Garlic and Fillings
These are starting points, so watch the colour of the crust rather than the clock.
- Air fryer: brush both outer faces with oil as above and cook at 180°C (360°F) for about 4 minutes, then flip and cook another 3–4 minutes. Pin the top slice with a cocktail stick so the fan does not lift it. Our article on olive oil in an air fryer covers the oil side in more detail.
- Oven, for a crowd: build the sandwiches, brush the tops, set them oiled side down on a preheated baking tray, brush the upper faces and bake at 220°C / 200°C fan / 425°F for 6–8 minutes, turning once.
- Garlic: rub the toasted outside of the finished sandwich with a cut clove of garlic, or warm a crushed clove gently in the tablespoon of oil for a minute before brushing. Our garlic bread with olive oil uses the same idea.
- Crispy cheese edge: after flipping, scatter a tablespoon of finely grated hard cheese into the pan around the sandwich so it fries into a lacy, crunchy frill.
- Fillings that suit olive oil: fresh basil leaves, thinly sliced tomato (pat it dry), roasted peppers, caramelised onion or a thin layer of pesto. Keep wet fillings thin, or the bread will steam.
On health, the honest framing is short. A grilled cheese is still a cheese sandwich. Swapping butter for olive oil changes the fat used for frying from one that is mostly saturated to one that is mostly monounsaturated oleic acid, which is a reasonable choice within a balanced diet, but it does not turn the sandwich into a health food.
Why Sidr & Stone
In a grilled cheese, the olive oil is fried into the crust and then tasted again as the finishing drops on top, so its freshness shows in both places. That 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; 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 grilled cheese; your pan, your cheese and your taste are the judges of that. What we will say is that it is single-estate Moroccan, rain-fed, organically grown and cold-pressed within hours of harvest, and that the product page carries the details of the current batch, so you can judge its freshness for yourself.
Frequently Asked Questions
Is olive oil OK for grilled cheese?
Yes. Brushed onto the outside of the bread and cooked over medium-low heat, olive oil gives an even, golden, crisp crust. In The Kitchn's 2022 method test it scored 7/10, slightly ahead of plain butter at 6.5/10.
Why does olive oil make grilled cheese crispier than butter?
Olive oil is pure fat, so it fries the bread directly. Butter is at least 80% milk fat, and the rest is mostly water, which steams the bread, plus milk solids, which brown in patches and can scorch.
How much olive oil do you need for one grilled cheese?
About 1 tablespoon (15ml) for one sandwich: roughly 1½ teaspoons brushed onto each outer face, edge to edge. Brushing uses less oil and browns more evenly than pouring oil into the pan.
Do cheese and olive oil go together?
Yes. Olive oil and cheese are a long-standing Mediterranean pairing, from mozzarella and tomato to aged sheep's cheese drizzled with oil. Mature cheddar, Gruyère and mozzarella all work well in an olive oil grilled cheese.
Is Sidr & Stone's olive oil good for grilled cheese?
Yes. It is a single-estate, cold-pressed, unfiltered extra virgin olive oil, so it suits both the brushed crust and the finishing drops on top. Taste it on bread first and brush a little less if you prefer a milder crust.
Can I use oil instead of butter in grilled cheese without it going greasy?
Yes, if you brush the oil onto the bread rather than pouring it into the pan, use sturdy bread, and keep the heat at medium-low. Greasiness usually comes from too much oil in a pan that is not hot enough.
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
Olive oil grilled cheese works because it removes the two things that make a butter crust uneven: water and milk solids. What is left is pure fat, brushed thinly onto the bread, frying it into an even, crackly gold while a lid and a gentle heat give the cheese time to melt. Grate the cheese, oil the bread rather than the pan, cook low, and finish with a few drops of raw oil and a pinch of salt. If you miss the taste of butter, mix a little in; if you came for the crust, you will not need to.
If you want an oil with a clear origin for the crust and the finishing drizzle, 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.
