    It’s so worth it to make your own vegan French onion dip from scratch with slow cooked caramelized onions and vegan sour cream because it is just SO much more delicious than anything you could ever buy ready-made.

    This is seriously up there with the most delicious dips you could ever taste. It’s seriously incredible.

    And it’s actually really easy too, the most difficult part is caramelizing the onions and really, it’s not difficult at all, it just takes a while.

    Ingredients You’ll Need:

    Ingredient Notes

    • Raw cashews – these are blended up with the water, lemon juice, apple cider vinegar, nutritional yeast and sea salt to make up the cashew sour cream. You don’t need to soak the cashews first unless your blender is a weaker model. If you’d prefer to soak them first, then add them to a bowl, pour over hot water from the kettle and leave them to soak for 15 minutes, then drain and rinse.
    • Lemon juice – this should ideally be freshly squeezed lemon juice for the best flavor.
    • Vegan mayonnaise – it’s ideal to use a full fat, ultra creamy vegan mayonnaise in this recipe.

    How To Make Vegan French Onion Dip

    • Step 1. Make the cashew sour cream. Add cashews, water, lemon juice, apple cider vinegar, nutritional yeast and sea salt to your blender jug and blend until smooth. Set aside.

    Chef’s Tips

    Blending. If your blender has a very wide base, then it may be best to double the recipe. Trust me you won’t mind at all having a double batch of this dip around, especially since it also keeps well in the fridge. The reason for this is that when you’re blending up the cashew sour cream, if your blender has a wide base then there won’t be enough volume for the blades to gain traction. This only applies to the really wide base blenders. Regular tall blenders won’t have a problem.

    Serving. The best way to serve this vegan French onion dip is with crinkle cut potato chips. Sure, crackers and corn chips will also be delicious but the BEST way to serve it is with potato chips, hands down.

    Storing and Freezing

    Keep leftovers in the fridge and enjoy within 7 days. It is also freezer friendly for up to 3 months. Thaw overnight in the fridge, stir well and then serve.

    • Make the cashew sour cream. Add cashews, water, lemon juice, apple cider vinegar, nutritional yeast and sea salt to your blender jug and blend until smooth. Set aside.
    • Caramelize the onions. Add olive oil and chopped onions to a frying pan or skillet and heat on low heat.

    Notes

    1. Raw cashews. You don’t need to soak the cashews first unless your blender is a weaker model. If you’d prefer to soak them first, then add them to a bowl, pour over hot water from the kettle and leave them to soak for 15 minutes, then drain and rinse.
    2. Blending. If your blender has a very wide base, then it may be best to double the recipe. Trust me you won’t mind at all having a double batch of this dip around, especially since it also keeps well in the fridge. Alternatively you can just double the cashew sour cream only and then just use half of it in this dip and keep the other half back and use it for other things. The reason to double it is if your blender has a wide base then there won’t be enough volume for the blades to gain traction. This only applies to the really wide base blenders. Regular tall blenders won’t have a problem.
    3. Storing. Keep leftovers in the fridge and enjoy within 7 days.
    4. Freezing. It is also freezer friendly for up to 3 months. Thaw overnight in the fridge, stir well and then serve.
    5. Nutritional information is for the dip only and excludes potato chips.
