Ingredient Notes

Here is a full breakdown of everything you’ll need to make this vegan French onion dip recipe:

• Avocado Oil: Provides a neutral base for caramelizing the onions. Its high smoke point makes it my preferred choice for sautéing.
• Onion: When caramelized, onions give the dip its classic flavor and sweetness. Use yellow or sweet onions to develop a rich, deep flavor.
• Cashews: Create an ultra-creamy, dairy-free base for the dip. Opt for raw, unsalted cashews for the best texture and flavor.
• Vegan Greek Yogurt: Adds tanginess and extra creaminess to the mixture. Look for vegan Greek-style yogurt made from almond, coconut, or soy milk in the refrigerated section of your usual grocery store.
• Garlic: Fresh garlic cloves perfectly enhance the savoriness of the dip.
• White Vinegar: Adds a touch of acidity to balance the sweetness of the onions and cut through the richness of the cashews and yogurt.
• Dry Seasonings: I use onion and garlic powder to intensify the savoriness of the dip, smoked paprika and red pepper flakes for a smoky kick, and salt to balance the flavors. You can adjust the amount of pepper flakes to suit your spice preference. 
• Plant Milk: Helps move the blender along to achieve a smooth, creamy consistency. Use plain, unsweetened milk (like almond, soy, or oat) to keep the flavors neutral.
• Fresh herbs: I use Italian parsley and chives to add a fresh flavor and a pop of color.

Substitutions

• Avocado Oil: Swap olive oil in the same quantity for a fruitier flavor profile.
• Cashews: For a nut-free version, use an equal amount of sunflower seeds (the taste won’t be as sweet, but the dip will still have a creamy texture).
• Vegan Greek Yogurt: If you don’t have vegan yogurt, try equal parts coconut cream for a more decadent, slightly sweeter dip.
• Garlic: If you don’t have fresh garlic cloves, replace them with extra garlic powder. Use ¼ teaspoon of garlic powder for every fresh clove you’re missing.
• Vinegar: You can replace regular vinegar with apple cider vinegar using a 1:1 ratio.
• Seasonings: Feel free to adjust the seasonings to your liking. Add more red pepper flakes or cayenne for spice, cracked black pepper for a savory kick, or mustard powder for a tangy sharpness.

How to Make

This vegan French onion dip couldn’t be easier to make! Just follow my tips for the best results.

Preparation

Boil raw cashews for 5 minutes or soak them in just-boiled water for 25 minutes until softened. Finely dice the onions and peel the garlic cloves.

Cooking

Step 1
Heat the avocado oil in a pan over medium. Add the diced onions and cook for a few minutes until they become translucent. Stir frequently to prevent the onions from sticking or burning! Reduce the heat to low and cook the onions for another 15-20 minutes until they caramelize to a golden-brown color. If the onions start to stick or brown too quickly, add a splash of water.

Step 2
Drain the soaked cashews and add them to a high-speed blender with caramelized onions, vegan Greek yogurt, garlic cloves, white vinegar, and dry seasonings. Blend the mixture until smooth, adding plant milk one tablespoon at a time as needed to keep the blender moving. Scrape down the blender's sides a few times to ensure all the ingredients are fully incorporated.

Step 3
Transfer the mixture to a bowl and stir in finely chopped Italian parsley. Garnish your final vegan French onion dip with chopped chives before serving with ruffled potato chips (or your favorite veggies!).

Expert Tip

The secret to an epic vegan French onion dip is proper caramelization of the onions! Cooking them slowly over low heat prevents burning and allows their natural sugars to develop, resulting in a deep, rich sweetness essential to the dip's flavor.

Skipping or rushing this step can lead to a flat-tasting dip that lacks savory depth. Remember, perfectly caramelized onions are golden and melt-in-your-mouth tender, not burnt or crispy.

Cooking Tips

• Soak the Cashews: Fully softened cashews blend into a much smoother consistency. You’ll know they’re ready when you can easily split them between your fingers.
• Add Milk Gradually: Add plant milk in small increments to reach a creamy dip texture without thinning it out too much.
• Chill for Flavor: For the best flavor, chill your vegan French onion dip for at least an hour to allow the flavors to meld.
