    How beautiful are these fries?! I just love cooking with colorful foods. And purple is my favorite color, so I'm extra excited about these fries.

    Sweet potatoes are such an incredible food. They have potassium and fiber. Plus, they are SO versatile. But today we're keeping it simple with the classic fry.

    Of course, you can easily dress up sweet potato fries to create so much flavor. Add spices for a delicious kick. And, for extra flavor, make a dipping sauce.

    For this recipe, we've got a Walnut Turmeric Aioli. It's a beautiful yellow color and filled with super foods. Let's jump in!

    Fries Ingredients

    • Purple Sweet Potatoes: Several large sweet potatoes will do.
    • Spices: nutritional yeast, parsley, garlic powder, salt, hot pepper flakes.
    • Lemon Juice: Lemon juice adds some acidity, and also helps the spices stick to the potatoes, since we aren't using any oil. You could sub apple cider vinegar.

    Aioli Ingredients‍

    • Walnuts: Many vegan aioli recipes use cashews, but I used walnuts, which offer a distinct nutritional profile and a richer flavor. If you want, you and use cashews instead.‍
    • Garlic: To create the classic aioli flavor.‍
    • Turmeric: I used turmeric spice, but you could use fresh turmeric if you have it on hand
    • Non-Dairy Milk: use any non-dairy milk you have. I like oat milk.‍
    • Salt
