Vegan Burger Sauce: Creamy Recipe + 6 More Vegan Sauces

The sauce that turns a veggie burger into an unforgettable experience

Look, I’ll be honest with you: for years I thought veggie burgers were a challenge for any chef. Not because of a lack of flavor, but because most—whether made from lentils, chickpeas, portobello, or quinoa—tend to be drier and less juicy than a good beef burger. And that’s where the unsung hero comes in: the sauce. A well-balanced vegan burger sauce can transform a veggie burger from “good” to “unforgettable.” It adds body, acidity, umami, and that creaminess that ties all the ingredients together.

Today I’m sharing my favorite recipe for a creamy vegan burger-style sauce. It’s 100% vegan, ready in 5 minutes, no cooking required, and has a deep flavor that’s a perfect match for any veggie burger. Get your ingredients ready, and let’s dive in.

Ingredients – Creamy vegan burger-style sauce (vegan special sauce)

Here are the exact amounts to yield about 1 cup (240 ml). This vegan burger sauce is versatile, easy to adjust, and comes together in a flash.

Ingredient	Amount (ml / oz / g)
Vegan mayonnaise (soy or avocado)	180 ml (6 oz)
Ketchup or tomato paste	30 ml (1 oz)
Dijon mustard	15 ml (0.5 oz)
Finely chopped pickles (cornichons or dill pickles)	30 g (1 oz)
Pickle juice	15 ml (0.5 oz)
Finely grated white or red onion	20 g (0.7 oz)
Garlic powder	2 g (½ teaspoon)
Smoked paprika	3 g (1 teaspoon)
Agave syrup or brown sugar	10 ml (2 teaspoons)
Apple cider vinegar	10 ml (2 teaspoons)
Salt	1 g (¼ teaspoon)

The secret to a vegan sauce with deep flavor

There are details that make the difference between a decent vegan burger sauce and one that makes you close your eyes. Here are my tips:

• Umami in two hits: The tomato paste plus the smoked paprika create an umami base that mimics the smoky flavor of a beef burger. Don’t skip them.
• Chill time: After mixing everything, let the sauce rest in the fridge for at least 30 minutes. The flavors meld, the onion softens, and the texture becomes more homogeneous.
• Hand-chopped pickles, never blended: The texture of small pickle bits adds crunch and a burst of acidity that gets lost when blended. Chop them with a knife.
• Adjust acidity and sweetness to your taste: The sauce should have a balance between acidic (vinegar + pickles) and sweet (agave). If it’s too acidic, add a bit more syrup; if too sweet, an extra splash of vinegar. Always taste it.
• Avocado vegan mayonnaise: If you can find a vegan mayo made with avocado, the creaminess is superior and gives an extra touch of healthy fat that wraps around the veggie burger.

Step by step: how to make this vegan burger sauce

1. In a medium bowl, place the vegan mayonnaise, ketchup, and Dijon mustard. Mix with a spatula or whisk until you have a smooth base.
2. Grate the onion very finely (you can use a Microplane grater). If you want it milder, pass it through a sieve and press slightly to remove excess liquid.
3. Chop the pickles into tiny cubes the size of a pinhead. Do not process them in a blender.
4. Add the grated onion, chopped pickles, and pickle juice. Stir well.
5. Add the garlic powder, smoked paprika, agave syrup, and apple cider vinegar. Mix until everything is combined.
6. Taste and adjust the salt. Remember that the pickles already add salt, so go easy.
7. Cover the bowl with plastic wrap and refrigerate for at least 30 minutes. Before serving, stir again, and if it has thickened too much, add a tablespoon of cold water.

6 more vegan sauces for your veggie burger

The same veggie burger can change completely with different vegan burger sauces. Here are six options I love:

Guacamole / avocado sauce

Mashed avocado with cilantro, lime juice, onion, and jalapeño. Creamy, fresh, and full of healthy fats. Perfect for black bean or portobello burgers.

Roasted red pepper hummus

Classic hummus (chickpeas, tahini, lemon) with roasted red pepper and paprika added. Its smooth, smoky texture goes well with lentil or chickpea burgers.

Tahini-lemon sauce

Sesame paste (tahini) thinned with lemon juice, garlic, and a little water. Light, tangy, and earthy. Ideal for falafel-style or chickpea burgers.

Homemade chipotle ketchup

Ketchup mixed with chipotle in adobo, a touch of vinegar, and sugar. Smoky and spicy. Perfect with portobello or quinoa burgers.

Vegan garlic mayonnaise (vegan aioli)

Vegan mayo with fresh crushed garlic, lemon juice, and chopped parsley. Bold and aromatic. Great with beet and quinoa burgers. If you want to master the technique for the classic version (and then veganize it), check out my recipe for garlic mayonnaise with store-bought mayo.

Vegan BBQ sauce

Base of ketchup, apple cider vinegar, molasses or syrup, smoked paprika, garlic powder, and a touch of liquid smoke (optional). Sweet, smoky, and thick. Perfect for lentil burgers or any veggie that needs intense flavor. The base is the same as my spicy barbecue sauce: just make sure to use sugar and no honey.

Quick comparison table:

Sauce	Profile	Best with
Guacamole/avocado	Creamy, fresh	Black bean, portobello
Roasted red pepper hummus	Smooth, smoky	Lentils, chickpeas
Tahini-lemon	Light, tangy, earthy	Falafel, chickpea
Chipotle ketchup	Smoky, spicy	Portobello, quinoa
Vegan aioli	Bold, aromatic	Beet, quinoa
Vegan BBQ	Sweet, smoky	Lentils, portobello

Which veggie burger it pairs best with

The art of pairing a vegan burger sauce with a veggie burger is based on balancing texture and flavor. Here are my favorite combinations:

• Lentil burger: needs tangy, fresh sauces that cut through its earthy density. The pickle sauce from this recipe or a guacamole work wonderfully.
• Chickpea burger (falafel style): calls for a sauce with character based on tahini, like the tahini-lemon or a light hummus. The lemon acidity enhances the chickpea.
• Portobello burger: the mushroom has natural umami, but needs a smoky, sweet contrast. Vegan BBQ or a chipotle ketchup are ideal.
• Black bean burger: seeks freshness and creaminess. A smooth guacamole or avocado mayo suits it perfectly.
• Do you like spicy? My jalapeño sauce for burgers has a 100% vegan version (with vegan mayo and coconut yogurt) that works amazingly with any veggie burger.
• Quinoa and beet burger: it’s mild and slightly sweet. A creamy sauce like vegan aioli or the special sauce from this recipe wraps it without overpowering it.

Storage

Store this vegan burger sauce in an airtight glass jar in the fridge. It keeps in perfect condition for 3 to 5 days. Don’t freeze it, because the vegan mayo can separate and lose texture. Before using, take it out 5 minutes ahead and stir well with a spoon; if it has thickened too much, add a teaspoon of water or vinegar.

Frequently Asked Questions

What is the best vegan sauce for burgers?

There’s no single best one—it depends on the type of veggie burger. For lentil or chickpea burgers, a tangy, fresh sauce (like the pickle one) is ideal. For portobello, a smoky vegan BBQ. The key is balancing the burger’s dry texture with creaminess and a touch of acidity or umami.

What’s the difference between a vegan sauce and a vegetarian sauce?

Vegetarian sauces can contain dairy, egg, or honey (e.g., mayo with egg, cream). Vegan sauces contain no animal-derived ingredients. In this recipe everything is 100% plant-based: vegan mayo (egg-free), agave syrup instead of honey, etc.

Can I make this sauce without store-bought vegan mayo?

Yes, absolutely. You can prepare a base of soaked cashews (soak 1 cup raw cashews in hot water for 2 hours, drain, and blend with ½ cup water and 1 tablespoon apple cider vinegar) or use aquafaba (the liquid from cooked chickpeas) emulsified with neutral oil. The texture will be just as creamy.

How long does homemade vegan sauce last in the fridge?

Between 3 and 5 days in an airtight jar. After that, the onion can release water and the sauce may lose consistency. Don’t freeze it.

What sauce should I put on a lentil burger so it doesn’t turn out dry?

The best option is a vegan burger sauce with a mayo or avocado base that provides fat and creaminess. The recipe in this post, with its tanginess and crunchy pickle texture, is perfect. Also, a guacamole or a well-hydrated tahini-lemon sauce work great.
