Add all ingredients to a bowl and mix well until combined.
1 cup Sour cream, 1 teaspoon Sriracha, ½ teaspoon Garlic powder, ½ teaspoon Onion powder, pinch Salt, pinch Pepper, 1 teaspoon Paprika
Ideally, rest in the fridge overnight. Then serve and enjoy!
Notes
If your sour cream is especially thick, you can add a splash of milk or water to help thin out the sauce. This is especially helpful if your sweet potato fries are thin and break easily.
You can swap out the flavor profiles by using curry powder instead of the paprika, adding in a little cilantro and lime juice, or mixing in a dollop of honey mustard! Keep adjusting until it's exactly to your tastes.
While this sauce is made as a fry dip, you can absolutely use it on any sweet potato recipe. I've linked a bunch of my favorites below.
Like most sauces using dried spices, it gets better with rest! Try making it a few hours ahead of time so the flavors can meld.
