It happens to everyone, including us. The pan is hot, the garlic is sliced, and the bottle gives you that hollow last-inch gurgle. So: what can you use instead of olive oil?
There is an honest answer, and it depends entirely on what job the oil was doing. Olive oil is unusual in that it does three separate things at once — it carries heat, it carries flavour, and it carries a set of compounds that most other fats simply do not have. Almost every substitute can do one of those. Very few do two. None do all three. Here is how we would handle it, from a family that has been pressing olives for six generations and has, on occasion, run out too.
First, work out what you are actually replacing
Before you reach for anything, ask what the oil was there to do in this specific dish.
- A cooking medium. It is transferring heat into food, and you will not taste it much. Easy to replace.
- A structural fat. It is keeping a cake tender or an emulsion together. Replaceable, but the ratio matters.
- The flavour itself. It is the dressing, the drizzle, the last thing to touch the plate. This is where substitutes fall apart, because there is nothing else in the kitchen that tastes like fresh olive juice.
Get that right and the rest is arithmetic.
The best olive oil substitutes, use by use
For sautéing, softening and roasting
This is the forgiving end. Swap 1:1 and you will be fine.
- Butter — the best flavour substitute here, though it browns fast and burns at a lower temperature. Cut it half-and-half with a neutral oil if the pan is running hot.
- Avocado oil — the closest neutral analogue, similarly monounsaturated, essentially flavourless. Good, expensive, and it will not season the dish for you.
- Ghee or clarified butter — the milk solids are gone, so it handles heat far better than butter and brings a nutty depth.
- Duck or pork fat — outstanding for roasting potatoes and vegetables. Not remotely interchangeable in anything delicate.
For baking
Looking for a substitute for olive oil in baking? You have more room than you think, because here the oil is doing structural work — coating flour proteins, keeping crumb tender.
- Any neutral liquid oil (sunflower, grapeseed, light rapeseed) — swap 1:1. The cake will be tender and slightly duller in flavour.
- Melted butter — use about 1¼ cups butter for every 1 cup oil, because butter is roughly 15–18% water. Richer, firmer, less moist on day three.
- Unsweetened applesauce or mashed banana — replaces up to half the oil in a sweet batter. Denser, more moist, noticeably fruitier. Do not replace all of it unless you want something closer to a pudding.
- Yoghurt — works at a 1:1 swap in quick breads and muffins, adds tang and tightens the crumb.
Worth saying plainly: an olive oil cake made with sunflower oil is no longer an olive oil cake. It is a plain oil cake, and it will taste like one.
For high-heat searing and frying
Fresh, low-acidity extra virgin olive oil handles ordinary home cooking heat better than its reputation suggests — but if you are deep-frying at volume, you should not be spending your best bottle on it anyway. Use refined avocado, peanut or high-oleic sunflower oil, 1:1, and keep the good stuff for the finish.
For dressings, drizzles and anything raw
Here is where we stop being diplomatic. There is no substitute.
You can build a vinaigrette from walnut oil, hazelnut oil or a good cold-pressed rapeseed, and some of them are genuinely lovely — walnut oil with bitter leaves and pear is a beautiful thing. But they are different ingredients with their own agenda, not stand-ins. A neutral oil in a vinaigrette gives you acid and fat and nothing in between: the dressing tastes sharp and thin because the round, grassy, faintly bitter middle has been removed. If the dish is raw, either use olive oil or cook something else tonight.
What you actually give up in the swap
Calorie for calorie, most cooking fats are close cousins. The difference is not really in the fat. Extra virgin olive oil is the only common kitchen oil that is a mechanically extracted fruit juice rather than a refined product, and it arrives carrying its own phenolic compounds — the family that includes oleocanthal, the compound responsible for that peppery catch at the back of your throat. Refining strips them out. Seeds never had them in the first place.
That matters beyond flavour. The European Food Safety Authority permits a health claim on olive oils that carry at least 5 mg of hydroxytyrosol and related compounds per 20 g of oil, for the protection of blood lipids from oxidative damage. It is a narrow, dose-dependent claim — and it is the only part of the olive oil story that a substitute cannot approximate at any price. If you want the detail, we go through it properly in our guide to polyphenols in olive oil.
The substitution nobody warns you about
The riskiest swap is not butter for oil. It is olive oil for olive oil.
Bottles labelled “pure”, “light” or simply “olive oil” are largely refined oil with a small proportion of virgin oil blended back for colour and smell. “Light” refers to flavour, not calories. Pomace oil sits a rung lower still. These read as the same product on the shelf, cost less, and quietly deliver a fraction of what you were buying olive oil for — which is exactly the trade we unpack in why supermarket olive oil is usually a false economy.
A landmark analysis at the University of California, Davis found that a majority of imported oils sampled from US retail shelves and sold as “extra virgin” failed the sensory standards for that grade. Nobody had to substitute anything at home. It had already been done for them, upstream.
The short version
Cooking with it? Butter, ghee or avocado oil, 1:1, and no one will notice. Baking with it? Neutral oil 1:1, or butter at 1¼:1. Frying? Refined oil, every time. Dressing, dipping, finishing? Buy another bottle — that is the recipe.
And if the substitute question keeps coming up, it is usually a sign the bottle is doing too many jobs. Most Italian kitchens keep two: something serviceable for the pan, and something serious for the plate. Learning to tell them apart is the whole skill, and we lay out the tests in what actually makes a quality olive oil.
Stop substituting
Olive Father is single-source extra virgin olive oil from one family grove in Calabria — one harvest, one mill, harvest date on every bottle, nothing blended in. It is the bottle you keep for the finish, and it is honest enough for the pan too. See the range and taste the difference a real olive makes.
