🥑 Dairy-Free Avocado Burger Sauce
Most classic burger sauces are already dairy-free, so a "dairy-free burger sauce" that is just mayonnaise with a different label is not much of a recipe. This is a different sauce entirely — no mayo, no egg, no dairy anywhere — built on ripe avocado and tahini blended with lime and garlic. It goes on thick and green, it tastes nutty and bright instead of rich and sweet, and it is the one sauce here that adds freshness to a burger rather than more fat on top of fat.

From I Love Hamburger — ilovehamburger.com
Ingredients
- 1 large ripe avocado, flesh scooped out (about 200 g)
- 2 tbsp tahini (well stirred) (30 g)
- 2 tbsp fresh lime juice (30 ml)
- 2 tbsp cold water, plus more to thin (30 ml)
- 1 tbsp extra-virgin olive oil (15 ml)
- 1 clove garlic, finely grated (about 1 tsp)
- 2 tbsp chopped fresh cilantro or dill (5 g)
- ¼ tsp ground cumin (0.5 g)
- Salt to taste
Instructions
- Put the avocado flesh, tahini, lime juice, water, olive oil, garlic, herbs, and cumin in a small food processor or blender.
- Blend until completely smooth and pale green, scraping down the sides once. It should be thick enough to hold a soft ridge — add water 1 tablespoon at a time if it is stiffer than that.
- Season with salt and taste. Tahini goes slightly bitter without enough acid, so if it tastes flat add lime juice rather than salt.
- Use it the same day it is made. Spread it on the bottom bun where it will not slide off the patty.
🫙 Storage
Best the day it is made. To keep it overnight, press plastic wrap directly onto the surface so no air touches it and refrigerate up to 2 days — the extra lime juice slows browning but does not stop it. Any grey on top can be scraped off. Do not freeze.
🔁 Substitutions
- No tahini? Use 2 tbsp of smooth unsweetened cashew or sunflower-seed butter for the same body without the sesame.
- For a pourable dressing rather than a spread, blend in water 1 tbsp at a time until it ribbons off the spoon.
- Swap cilantro for dill or flat-leaf parsley, and add a pickled jalapeno if you want heat.
🍔 What to put it on
Pair it with shredded lettuce, tomato, and quick-pickled red onion. It especially shines on these burgers:

Frequently asked questions
Why not just use dairy-free mayo in a classic burger sauce?
You can, and it works — most mayonnaise contains no dairy in the first place, so swapping in a plant-based mayo makes our classic burger sauce dairy-free in one step. We did not want to publish that as a separate recipe, because it is the same sauce. This one earns its own page: no mayo, no egg, no dairy at all, and a completely different flavor — nutty, herby and bright rather than creamy and sweet.
How do I stop it turning brown?
Browning is the avocado reacting with air, so limit the air. Blend in all the lime juice (acid slows the reaction), then press plastic wrap flat against the surface of the sauce instead of just covering the container. Even so, treat it as a same-day sauce; two days is the practical limit.
Is it good on a beef burger, or only veggie ones?
Both, but it does different jobs. On a bean or veggie patty it supplies the richness. On beef it works as a cooling, acidic counterweight — think of it the way you would guacamole, not the way you would special sauce, and skip the cheese so the flavors do not fight.
