Ingredients Needed for Savory Spicy Butternut Squash Sweet Potato Soup

This savory spicy butternut squash sweet potato soup is all about bold flavor with simple, real ingredients. Most are pantry staples or easy to find, and you can swap a few if needed. Here’s what you’ll need:

• For the Soup Base:
  • 1 medium butternut squash (about 2 lbs/900g), peeled, seeded, and cubed
  • 2 medium sweet potatoes (about 1 lb/450g), peeled and cubed
  • 1 large yellow onion, chopped
  • 3 cloves garlic, minced
  • 1-inch piece fresh ginger, peeled and minced (about 2 tsp)
  • 3 tbsp olive oil (or avocado oil for a neutral flavor)
  • 1 tsp sea salt (plus more to taste)
  • 1/2 tsp freshly ground black pepper
• Spices for Heat & Depth:
  • 1 tsp smoked paprika (adds a subtle smoky flavor)
  • 1/2 tsp ground cumin
  • 1/2 tsp ground coriander
  • 1/4 to 1/2 tsp cayenne pepper (adjust to taste; go easy if heat-averse!)
  • 1/2 tsp ground cinnamon (sounds odd, but trust me—it works!)
• Liquids & Creaminess:
  • 4 cups (950ml) vegetable broth (I prefer low-sodium for better control)
  • 1 can (13.5 oz/400ml) full-fat coconut milk (shake well before opening)
• For Serving:
  • Fresh cilantro or parsley, chopped (optional but highly recommended)
  • Crusty bread or homemade croutons (for dunking!)
  • Toasted pumpkin seeds or a swirl of coconut cream (for extra flair)

Ingredient tips: Pick a butternut squash that feels heavy for its size and has matte skin—shiny means it’s underripe. For the sweet potatoes, go for orange-fleshed varieties for the best creamy sweetness. If you want to save time, look for pre-cubed squash and sweet potatoes at the grocery store. And if you’re out of coconut milk, cashew cream or even a splash of oat milk will work (just don’t use skim dairy milk—it’ll get lost in the bold flavors).

Substitutions: Use white potatoes if you’re out of sweet potatoes (the soup will be less sweet, but still yummy). For extra protein, add a drained can of chickpeas before blending. Want it less spicy? Swap cayenne for a pinch of chili powder, or leave it out entirely.

Equipment Needed

• Large Baking Sheet: For roasting the squash and sweet potatoes. If you don’t have one, use two smaller trays and rotate halfway through.
• Chef’s Knife & Cutting Board: A sharp knife makes peeling and chopping butternut squash way easier (trust me, dull knives are no fun with tough squash).
• Vegetable Peeler: For peeling squash and sweet potatoes. If you’re in a pinch, a paring knife works, but a peeler saves time (and your fingers!).
• Large Soup Pot or Dutch Oven: Heavy-bottomed pots distribute heat more evenly and prevent burning. I’ve used a basic stock pot and my big enameled Dutch oven—both work.
• Immersion Blender or Countertop Blender: Immersion (stick) blenders are the easiest for soups—less mess and no transferring hot soup. But a regular blender gives ultra-smooth results. Just let the soup cool a bit before blending and blend in batches.
• Wooden Spoon or Silicone Spatula: For stirring and sautéing the aromatics.
• Ladle: Handy for serving—especially if you’re trying to avoid splashes!
• Measuring Cups & Spoons: For getting those spices just right.

Budget tip: If you don’t have an immersion blender, use a potato masher for a rustic texture—it’s not perfectly smooth, but still tasty. And if you only have a small pot, halve the recipe or blend in batches. I’ve done it all ways (even with a hand whisk in college!) and the soup still delivers.

How to Make Savory Spicy Butternut Squash Sweet Potato Soup

1. Preheat and Prep:
   
   Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup.
2. Peel & Chop:
   
   Peel and cube the butternut squash (about 1-inch/2.5cm pieces). Peel and chop sweet potatoes into similar-sized cubes. Chop the onion. Mince garlic and ginger. (Watch those fingers—squash can be slippery!)
3. Roast the Veggies:
   
   Spread squash, sweet potatoes, and onion evenly on the baking sheet. Drizzle with 2 tbsp olive oil, sprinkle with 1/2 tsp salt and 1/4 tsp pepper. Toss to coat.
   
   Roast for 25-30 minutes, tossing halfway through, until veggies are fork-tender and caramelized on the edges. (If you notice browning too quickly, lower the rack.)
4. Sauté Aromatics:
   
   While veggies roast, heat 1 tbsp olive oil in a large soup pot over medium heat. Add garlic and ginger. Sauté for 1-2 minutes until fragrant but not browned.
5. Add Spices:
   
   Sprinkle in smoked paprika, cumin, coriander, cayenne, and cinnamon. Stir for 30 seconds—your kitchen will smell amazing!
6. Combine Everything:
   
   Add roasted vegetables to the pot. Stir well to coat with spices.
7. Add Broth & Simmer:
   
   Pour in vegetable broth, scraping up any brown bits from the bottom (that’s flavor gold). Bring to a gentle boil, then reduce heat and simmer for 10 minutes.
   
   Troubleshooting tip: If the soup seems too thick, add a bit more broth or water—start with 1/4 cup (60ml) at a time.
8. Blend Until Smooth:
   
   Turn off heat. Use an immersion blender to puree soup directly in the pot until silky smooth. Or, cool slightly and blend in batches in a countertop blender (cover with a towel to avoid steam burns).
   
   If you like a chunkier soup, blend only half and return the rest to the pot.
9. Stir in Coconut Milk:
   
   Pour in the coconut milk, stirring until fully combined. Taste and adjust salt, pepper, and cayenne as needed. Warm through for another 2-3 minutes.
10. Serve & Garnish:
    
    Ladle into bowls. Top with chopped cilantro or parsley, a swirl of coconut cream, toasted pumpkin seeds, and a side of crusty bread.

Prep notes: If you’re prepping ahead, let the soup cool before storing. The flavors deepen overnight! If you end up with a soup that’s too spicy, add a dollop of plain yogurt (or coconut yogurt) to mellow it out. And if you want to get a little fancy, drizzle with chili oil for extra kick.

Cooking Tips & Techniques

• Roasting Is Key: Roasting the squash and sweet potatoes unlocks their natural sweetness and adds a caramelized depth. Don’t skip it, even if you’re tempted to boil—trust me, I’ve tried both ways, and roasting wins every time.
• Spice Levels: Start light on the cayenne, then adjust after blending. It’s easy to add more heat, but impossible to take it out. (Ask my family about the “soup so spicy we ate cereal for dinner” night!)
• Texture Tricks: For silkier soup, blend longer and add a splash of extra coconut milk at the end. For a rustic feel, leave a few chunks or mash by hand. If using a regular blender, cool soup slightly before blending and vent the lid.
• Layer Flavors: Sautéing garlic and ginger with spices before adding the veggies really deepens the flavor. Don’t rush this step—give it a good minute or two until your kitchen smells irresistible.
• Multitasking: Roast the veggies while prepping your garnishes or getting bread ready. If you’re short on oven space, microwave the squash and sweet potatoes for 5 minutes before roasting to cut down on time.
• Troubleshooting: Too thick? Add more broth. Too thin? Simmer uncovered for a few minutes to reduce. If your soup tastes flat, a squeeze of lemon or a dash more salt can work wonders.
• Consistency Matters: Use the same size cubes for squash and sweet potato so they roast evenly. And remember, soup thickens as it cools, so don’t panic if it looks a bit runny at first.

Honestly, this savory spicy butternut squash sweet potato soup is pretty forgiving. Even if you miss a step, it still turns out delicious. Just cook with your senses—taste, smell, and adjust as you go!

Variations & Adaptations

• Make It Creamier: For an ultra-rich soup, add 1/2 cup (120ml) cashew cream or a splash of heavy cream (if not vegan). I sometimes do this for special occasions or when I want a little extra indulgence.
• Go Extra-Spicy: Add a diced jalapeño with the aromatics, or finish with a swirl of hot sauce. My husband loves it this way—it’s his go-to when he wants a sinus-clearing dinner!
• Add Protein: Stir in a can of drained chickpeas or white beans before blending. This bulks up the soup for a heartier, more filling meal (great for growing kiddos or post-workout recovery).
• Switch Up the Veggies: Use acorn squash or pumpkin instead of butternut, or swap in carrots for some of the sweet potato. You can also add a handful of spinach at the end for extra greens.
• Dietary Swaps: For nut allergies, stick to coconut milk or oat milk. For a lower-carb soup, reduce the sweet potatoes and add more squash or cauliflower.
• Cooking Method: Short on time? Skip roasting and simmer the veggies right in the broth until soft, then blend. The flavor won’t be as deep, but it still works in a pinch (I’ve done this for quick lunches).

My personal favorite variation? I once added a peeled apple before roasting for a subtle sweetness—so good! It’s become an occasional twist when I have apples to use up. Don’t be afraid to play around and discover your own signature version.

Serving & Storage Suggestions

Serve this savory spicy butternut squash sweet potato soup piping hot, in big bowls or mugs. It’s perfect topped with fresh herbs, a swirl of coconut cream, and plenty of crusty bread. For a heartier meal, add a side salad or roasted chickpeas for crunch.

This soup pairs beautifully with a crisp white wine (like Sauvignon Blanc) or a mug of spiced chai. Want to keep things extra cozy? Serve with grilled cheese sandwiches—my kids’ favorite combo.

Storage: Let the soup cool completely, then transfer to airtight containers. It keeps in the refrigerator for up to 5 days. For longer storage, freeze in individual portions for up to 3 months (leave out the fresh herbs until serving). Thaw overnight in the fridge and reheat gently on the stovetop, stirring occasionally.

Reheating tips: If the soup thickens in the fridge, just add a splash of broth or water while warming. Stir well to bring back its silky texture. I swear, the flavors get even better after a day or two—the perfect make-ahead lunch or dinner!

Frequently Asked Questions

Can I make this soup ahead of time?

Absolutely! This savory spicy butternut squash sweet potato soup tastes even better the next day. Just let it cool, store in the fridge, and reheat on the stove or microwave when ready to serve.

Is this soup spicy?

It has a gentle kick from the cayenne, but you can easily adjust the heat to your liking. Start with less and add more if you like things spicy. If you’re making it for kids, use just a pinch or leave it out.

Can I freeze this soup?

Yes, this soup freezes beautifully. Portion into airtight containers, freeze up to 3 months, and thaw overnight in the fridge before reheating. Just wait to add fresh herbs until serving for the best flavor.

What can I use instead of coconut milk?

If you can’t use coconut milk, try cashew cream, oat milk, or even a splash of unsweetened almond milk. If dairy isn’t an issue, a bit of heavy cream or half-and-half works too.

How do I make the soup smoother?

For the silkiest texture, blend the soup thoroughly—an immersion blender works great, but a countertop blender gives an ultra-smooth finish. If you like it chunky, blend just half and leave some texture. Add a splash more coconut milk for extra creaminess if needed.
