The best mayonnaise substitute depends on what the mayo is doing in the recipe. Use Greek yogurt or sour cream for creamy salads, mashed avocado for spreads, hummus or tahini for egg-free richness, mustard for sharpness, and vinaigrette or olive oil for lighter dressings.
Best Mayonnaise Substitutes by Use
| Recipe | Best substitute | How to adjust |
|---|---|---|
| Chicken, tuna, or egg salad | Greek yogurt, sour cream, or half yogurt and half mayo | Add mustard, lemon, pepper, and herbs so it does not taste flat. |
| Sandwich spread | Avocado, hummus, mustard, or yogurt sauce | Spread thinly and season with acid and salt to taste. |
| Coleslaw | Greek yogurt, sour cream, or vinaigrette | Add vinegar and a little sweetener if needed. |
| Dips | Sour cream, Greek yogurt, hummus, tahini, or blended beans | Thin with lemon juice, water, or olive oil. |
| Baking | Plain yogurt, sour cream, or oil depending on the recipe | Do not swap blindly; mayo adds fat, moisture, and egg. |
| Egg-free option | Hummus, tahini sauce, avocado, or vegan mayo | Check labels for allergens and texture. |
Flavor and Texture Notes
Mayonnaise is creamy, fatty, mildly tangy, and stable in many cold dishes. Greek yogurt is tangier and lighter. Avocado is rich but browns. Hummus is thicker and more savory. Mustard is sharp and low in fat, so it works best as a flavor booster rather than a full creamy replacement.
Food Safety Notes
Perishable salads still need refrigeration, whether they use mayonnaise, yogurt, sour cream, chicken, eggs, tuna, or vegetables. Keep these foods cold, use clean utensils, and refrigerate leftovers promptly. If a dish sat out too long, do not rely on swapping the mayo to make it safe.
Allergen Checks
Mayonnaise often contains egg. Substitutes can introduce milk, sesame, soy, tree nuts, or other allergens. Check labels every time if allergies matter, especially for vegan mayo, tahini, hummus, yogurt, sour cream, and prepared dressings.
FAQ
What is the closest substitute for mayonnaise?
Greek yogurt or sour cream is closest for creamy salads and dips. For sandwiches, mashed avocado, hummus, or a yogurt-mustard sauce can work well.
Can Greek yogurt replace mayo?
Yes, especially in chicken salad, tuna salad, egg salad, dips, and dressings. It is tangier and less fatty than mayo, so add lemon, mustard, herbs, or a little olive oil if needed.
What is a dairy-free substitute for mayonnaise?
Mashed avocado, hummus, tahini sauce, vinaigrette, olive oil, mustard, or vegan mayo can work. Check labels because egg-free or dairy-free products may still contain other allergens.
Does replacing mayonnaise make a salad safe at room temperature?
No. Chicken salad, tuna salad, egg salad, dairy-based dressings, and many cut-vegetable dishes are still perishable and should be kept cold.
