Can You Use Olive Oil Instead of Butter?

Yes. Olive oil can replace butter in many recipes, especially for sautéing, roasting, vegetables, pasta, sauces and recipes that use melted butter. For suitable recipes, start with about 3 tablespoons of olive oil for every 4 tablespoons of butter.

Olive oil is not a direct substitute when butter must provide solid structure, aeration, milk-solid browning or flaky layers, as in creamed cakes, croissants, puff pastry and brown-butter recipes.

Quick Questions

Can olive oil replace butter?

Yes. Olive oil often works for sautéing, roasting, pasta and bakes that use melted butter. Recipes that rely on creaming or solid butter layers need adaptation.

How much olive oil replaces butter?

For suitable recipes that use butter mainly as melted fat, start with 3 tablespoons olive oil for every 4 tablespoons butter, measured by volume.

Can I use olive oil in cakes and muffins?

Often, especially in recipes that mix liquid fats into the batter. Recipes that cream butter and sugar need more care.

Should I bake with extra virgin or light olive oil?

Use extra virgin when you want its flavor in the result. "Light" olive oil is refined olive oil with a milder taste; "light" refers to flavor, not calories. See how Italian olive oil is classified.

Will olive oil change the taste?

Yes. Extra virgin olive oil (EVOO), the highest grade in the virgin olive-oil category, can contribute fruity, grassy, bitter or peppery notes.

Will the texture stay the same?

Not necessarily. Oil can give a soft eating texture, but it does not reproduce butter’s aeration or solid layers.

Is olive oil lower in calories?

Per tablespoon, no: olive oil has about 119 calories and butter about 102. At the 3-for-4 swap, 3 tablespoons of olive oil (about 357 calories) replace 4 tablespoons of butter (about 408), roughly 12% fewer.

How does the fat profile differ?

Olive oil is higher in monounsaturated fat and lower in saturated fat than butter.

Replacing butter is one practical way to use olive oil. For the broader nutritional context—including its fat profile, natural compounds, and human research—read our guide to what research supports about extra virgin olive oil benefits.

1. Start With Butter’s Job in the Recipe

Read the method before changing the ingredient. “Melt the butter” is a useful sign that liquid oil may work. “Cream the butter and sugar,” “cut cold butter into flour,” or “fold in a butter block” signals a structural job that needs a different approach.

Think about sautéing vegetables versus making croissants. Vegetables need a cooking fat. Croissants need layers of solid fat folded between sheets of dough. Those are different jobs, even when the ingredient list calls both ingredients “fat.”

Butter also contains water and milk solids, the nonfat components that contribute its characteristic browned flavor. Olive oil is essentially all fat. Changing one for the other can therefore affect more than taste.

2. When Olive Oil Can and Can’t Replace Butter

Quick breads, loaves raised with baking powder or baking soda rather than yeast, are a useful place to explore olive oil. Start with a tested oil-based recipe when you want dependable results.

Creaming, beating softened butter with sugar to trap air, is the important exception. Liquid oil cannot hold those air pockets in the same way. A conversion chart alone will not solve that difference. King Arthur Baking explains the role of creaming butter and sugar.

3. Use the Conversion Chart: 3 Parts Olive Oil for 4 Parts Butter

For suitable recipes where butter mainly functions as melted fat, start with three parts olive oil for four parts butter by volume. Harvard’s Nutrition Source recommends using about 25% less oil when replacing butter in many baked goods.

Butter is about 80% fat by weight; the rest is mostly water and milk solids. U.S. law requires at least 80% milkfat. Olive oil is essentially all fat, so recipes often need less oil than butter. The 3:4 ratio is a practical starting point by volume, not an exact equivalence calculated from butter’s fat percentage by weight. It does not replace butter’s water or structure.

For sautéing, use enough oil to suit the pan and ingredients rather than treating the chart as compulsory. Extra virgin olive oil suits ordinary home sautéing; see olive oil smoke point. For baking, follow the recipe’s tested instructions whenever available.

Replacing another liquid oil is a separate question. Olive oil can usually replace vegetable or canola oil in the same volume, with flavor as the main change. See Can You Use Olive Oil Instead of Vegetable Oil? For another liquid-fat comparison, see Olive Oil vs. Avocado Oil.

4. Expect Changes in Flavor and Texture

Extra virgin olive oil becomes a flavor ingredient. A gentle oil can suit a delicate cake; a more assertive oil can bring character to chocolate, citrus, herbs, or savory bread.

Cultivar, the variety of olive an oil is made from, is one reason oils range from delicate to assertive. The New York Olive Oil Open’s guide to 18 extra virgin olive oils shows how cultivar, origin and harvest information differ from bottle to bottle.

Taste the oil before adding it. Ask whether its bitterness, fruitiness, and peppery finish belong with the other ingredients. The best choice depends on the result you want.

Texture needs the same attention. An oil-based cake can feel soft at room temperature, but substituting oil does not automatically make every bake lighter or fluffier. The mixing method and recipe balance still matter.

Olive oil also will not create brown butter’s nutty milk-solid flavor. Your food can still brown during cooking; the missing element is the browned butter itself.

If replacing salted butter, check seasoning. Add salt thoughtfully rather than assuming every butter brand contributes the same amount.

5. Compare Calories and Fat per Tablespoon

Compared with butter, olive oil is higher in monounsaturated fat and lower in saturated fat. Replacing butter with olive oil generally lowers saturated fat and increases monounsaturated fat in the recipe, although total calories depend on the amount used and the rest of the ingredients. Harvard Nutrition Source.

Monounsaturated fat, a type of unsaturated fat abundant in olive oil, is the central nutritional distinction. Harvard’s Nutrition Source supports replacing saturated fats with unsaturated fats as part of a healthy dietary pattern. Read Harvard’s guidance on healthy fats.

Both ingredients are calorie-dense. Tablespoon for tablespoon, olive oil has more calories; at the 3-for-4 swap, the recipe ends up with slightly fewer. Replacing butter with olive oil does not make a recipe healthy by itself: sugar, portion size and the overall recipe still matter.

Bottom Line

For your next recipe, check the mixing method, use the chart only where liquid fat fits, and choose an oil whose flavor suits the dish.

For a dependable first bake, start with a tested olive-oil recipe. Keep the original method when you need butter’s aeration, browned milk solids or flaky layers.
