Substitute for olive-oil in salad-dressings
Quick answer
For most vinaigrettes, avocado oil is the closest substitute — use it 1:1. If you want something more neutral, a good-quality neutral oil like grapeseed oil works at a 1:1 ratio but will produce a noticeably blander dressing. Walnut oil is a strong option for specific salads but is not a general-purpose swap.

| Rank | Substitute | Ratio (replaces 1 cup olive-oil) | Notes |
|---|---|---|---|
| #1 | Avocado oil | 1:1 (e.g., 3 tbsp avocado oil for 3 tbsp olive oil) | Avocado oil has a mild, slightly buttery flavor and a similar fat composition to olive oil, so it doesn't disrupt the acid-to-fat balance in a vinaigrette. It stays fluid at refrigerator temperature, which matters if you're storing dressing — unlike some oils, it won't solidify in the jar. Widely endorsed by Serious Eats and America's Test Kitchen as the most seamless swap for olive oil in cold applications. |
| #2 | Grapeseed oil | 1:1 (e.g., 3 tbsp grapeseed oil for 3 tbsp olive oil) | Grapeseed oil is very neutral in flavor, which makes it reliable but also means the distinctive fruity, peppery character of olive oil disappears entirely. Works well when the dressing relies heavily on aromatics (garlic, herbs, citrus) and olive oil flavor isn't load-bearing. Stays liquid when cold. A widely cited mainstream substitute, but the result is noticeably less complex. |
| #3 | Walnut oil | 1:1 (e.g., 3 tbsp walnut oil for 3 tbsp olive oil) | Walnut oil has a pronounced nutty flavor that pairs well on bitter greens (arugula, radicchio, endive) or grain salads with nuts and cheese. It's a poor general-purpose swap — the flavor is too assertive for mild lettuces or simple lemon vinaigrettes. Spoils quickly once opened; only use fresh oil from a recently opened bottle. Recommended by Food52 and Bon Appétit specifically in French-style salad contexts. |
| #4 | Sunflower oil | 1:1 (e.g., 3 tbsp sunflower oil for 3 tbsp olive oil) | Works in a pinch and stays liquid when refrigerated, but the flavor is flat. Best treated as a last-resort neutral oil — similar in outcome to grapeseed oil, though grapeseed is generally considered cleaner-tasting by most cook sources. The dressing will be functional but noticeably less interesting. |
Why salad-dressings is different
Salad dressings are one of the few uses where olive oil's flavor is front-and-center rather than a background cooking medium. In a simple vinaigrette — oil, acid, salt — the oil is typically 50–75% of the volume, so its flavor is not masked by heat or other strong ingredients. Cold temperature behavior also matters: olive oil solidifies slightly when refrigerated, and some substitute oils behave differently, affecting the texture of stored dressings.
Common mistakes
The most common mistake is swapping in a strongly flavored oil (like sesame oil or coconut oil) at a 1:1 ratio — both overpower the dressing entirely and are not appropriate general substitutes. A second frequent error is using a refined, deodorized olive oil substitute that's also high in saturated fat (like coconut oil), which will solidify in the refrigerator and produce a greasy, congealed dressing. Always check that your substitute oil stays liquid at 40°F / 4°C if the dressing will be stored.
In a vinaigrette, oil isn’t just a carrier — it’s the structural and flavor backbone of the dressing. Olive oil’s mild bitterness and fruitiness are what give a classic French vinaigrette or a lemon-herb dressing its character, and no neutral oil fully replicates that. Avocado oil is the strongest substitute because it shares a similar monounsaturated fat profile and a subtle richness that doesn’t fall completely flat, but you should expect a slightly blander result than what you’d get from a quality extra-virgin olive oil.
If you’re storing dressing in the refrigerator, confirm your substitute stays pourable when cold — avocado oil, grapeseed oil, and sunflower oil all pass this test. Walnut oil is worth keeping in mind specifically for bitter-green salads where its nuttiness is an asset rather than a mismatch, but it has a short shelf life after opening and shouldn’t be treated as a pantry-staple swap.
Frequently asked questions
- Can I use sesame oil instead of olive oil in a salad dressing?
- Not as a 1:1 substitute. Toasted sesame oil is extremely strong — it functions as a flavoring agent, not a base oil. If you want to use it, limit it to 1 tsp per 3 tbsp of a neutral base oil like grapeseed oil, and only in dressings where that sesame flavor fits (Asian-style slaws, grain bowls).
- Will my vinaigrette taste the same without olive oil?
- No. Olive oil contributes a fruity, sometimes peppery flavor that is genuinely distinctive. Avocado oil comes closest in body and mouthfeel, but the flavor profile shifts noticeably. If the recipe is olive-oil-forward (e.g., a simple lemon-herb vinaigrette for a Greek salad), the substitute will produce a blander result.
- Does the type of olive oil I'm replacing matter when choosing a substitute?
- Yes. If the recipe calls for extra-virgin olive oil, it's relying on flavor — use avocado oil or walnut oil (context-dependent) to get the closest result. If the recipe calls for "light" or "pure" olive oil, it wants a neutral fat, and grapeseed oil or sunflower oil will replicate that intent more accurately.
