Key Ingredients and Swaps

• Sweet potatoes: The base of the soup, adding natural sweetness, body, and a smooth texture when blended. Use orange-fleshed sweet potatoes, such as Beauregard or Jewel, for a naturally sweet flavor and creamy texture when blended. 
• Full-fat coconut milk: Creates a rich, creamy consistency. Full-fat canned coconut milk works best, but light coconut milk can be used for a thinner, less rich soup.
• Buffalo hot sauce: Provides the signature spicy, tangy flavor. Start with less and add more to taste.
• Yellow onion and garlic: Build the savory flavor of the soup. You can use shallots to replace onion and garlic
• Paprika: Adds depth and complements the sweetness of the potatoes. Swap for chilli pepper.
• Vegetable broth: Adds flavor and helps achieve the desired consistency. Homemade mushroom broth can also be used for more Unami flavor. Water can be substituted, although the soup will be less flavorful.
• Apple cider vinegar: Adds fresh flavor and balances the richness of the coconut milk. You can swap for lime or lemon juice.
• Vegan Worcestershire sauce: Adds savory depth. Check the label for gluten-free ingredients and dietary compatibility.
• Fresh basil: Adds a fresh herbal flavor when blended into the finished soup. You can also use cilantro or parsley.

Tips and FAQs

How spicy is Buffalo Sweet Potato Soup?

The soup has a noticeable buffalo-style heat balanced by the sweet potatoes and coconut milk. Use 1 tablespoon of hot sauce for a milder soup or increase it to 2 tablespoons for more heat.

Can I make the soup without coconut milk?

Coconut milk gives the soup its creamy texture and richness. You can substitute another unsweetened, dairy-free cooking cream, but the flavor and consistency may change.

How can I make the soup thicker or thinner?

For a thicker soup, add another small sweet potato and blend it as directed. For a thinner consistency, blend in additional broth or water a little at a time.

Can I make this soup ahead of time?

Yes. The soup reheats well, making it a good option for preparing lunch or dinner in advance. It tastes even better then next day.
