Perfect for fall and winter, this vibrant orange soup is both nourishing and delicious, making it a go-to for chilly nights or soothing lunches.

Rooted in harvest-inspired cooking, this recipe blends two power-packed vegetables — butternut squash and sweet potato — and spices them up with chili, ginger, and warming aromatics. The result? A silky, velvety soup with just the right balance of sweet, spicy, and savory.

Whether you’re pairing it with crusty bread or sipping it from a mug, this soup offers a satisfying depth of flavor in every spoonful.

Ingredients Overview

Let’s take a look at the flavorful components that build this rich, spiced soup:

• Butternut Squash: Naturally sweet with a silky texture when roasted and blended. You can use fresh or pre-cut squash cubes. For convenience, frozen squash works too.

• Sweet Potatoes: These enhance the sweetness and creaminess of the soup. Choose orange-fleshed varieties for deeper color and flavor.

• Onion & Garlic: Provide a savory backbone and balance the sweetness of the vegetables.

• Fresh Ginger: Adds warmth and a subtle heat that complements the root vegetables. Use grated or minced fresh ginger for the best flavor.

• Chili Flakes or Fresh Chili: Gives the soup its signature kick. Adjust the amount to match your heat preference.

• Vegetable or Chicken Broth: Forms the soup’s base. Use vegetable broth for a vegan version, or chicken broth for a heartier depth.

• Coconut Milk (optional): Adds a creamy finish and mellow richness that pairs beautifully with spice. You can also use heavy cream, but coconut milk keeps it dairy-free.

• Warm Spices: Ground cumin, cinnamon, smoked paprika, or curry powder round out the flavor and add complexity.

• Lime or Lemon Juice: A splash of acidity at the end lifts and brightens the soup.

• Salt & Pepper: Essential for seasoning and bringing out all the natural flavors.

Ingredient Swaps & Options

• Dairy-Free: Use coconut milk or almond cream.

• Spice Control: Omit chili or ginger for a mild version, or add cayenne or sriracha for more heat.

• Add Protein: Stir in lentils or top with crispy chickpeas or grilled chicken.

• No Blender? Mash with a potato masher for a rustic, chunky version.

Always roast or sauté your vegetables first — this brings out their natural sweetness and enhances the depth of flavor.

Step-by-Step Instructions

1. Roast the Vegetables

Preheat oven to 400°F (200°C). On a large baking sheet, toss together:

• 1 small butternut squash (peeled, seeded, cubed)

• 2 medium sweet potatoes (peeled, cubed)

• 2 tbsp olive oil

• Salt and pepper

Spread in a single layer and roast for 25–30 minutes, or until golden and tender.

Roasting tip: Don’t overcrowd the pan. You want caramelization, not steaming.

2. Sauté Aromatics

In a large pot or Dutch oven, heat 1 tbsp olive oil over medium heat. Add:

• 1 medium onion, diced

• 2 garlic cloves, minced

• 1 tbsp grated fresh ginger

Sauté for 5–7 minutes, stirring occasionally, until soft and fragrant.

3. Add Spices

Stir in:

• 1 tsp ground cumin

• ½ tsp smoked paprika or curry powder

• ¼ tsp cinnamon

• ½ tsp chili flakes (adjust to taste)

Toast the spices for 30–60 seconds to release their aromas.

4. Combine & Simmer

Add the roasted squash and sweet potato to the pot. Pour in:

• 4 cups vegetable or chicken broth

Bring to a boil, then reduce to a simmer. Cook uncovered for 10–15 minutes to let flavors meld.

5. Blend Until Smooth

Use an immersion blender directly in the pot, or carefully transfer in batches to a countertop blender. Blend until silky smooth.

Return the soup to the pot and stir in:

• ½ to 1 cup coconut milk (to taste)

• Juice of ½ lime or lemon

Adjust seasoning with salt, pepper, and more chili if desired.

6. Serve & Garnish

Ladle into bowls and top with:

• A drizzle of coconut milk or cream

• Toasted pumpkin seeds or crispy chickpeas

• Fresh herbs like cilantro or parsley

• Extra chili flakes for heat

Serve with warm naan, crusty bread, or a side salad.

Tips, Variations & Substitutions

• Make It Ahead: This soup keeps beautifully. Store in the fridge up to 4 days or freeze for up to 3 months.

• Texture Control: For a thinner soup, add more broth or water. For extra creaminess, increase the coconut milk.

• Flavor Boost: Add a tablespoon of miso paste, peanut butter, or red curry paste for deeper umami.

• Protein Add-Ins:

  • Stir in cooked red lentils or white beans.

  • Top with grilled tofu or shredded rotisserie chicken.

• No Roasting Time? Sauté the veggies in the pot until soft, then follow the rest of the steps.

Common mistake: Using too much liquid early on. Add broth gradually to control consistency before blending.

FAQs

Q1: Can I use canned butternut squash or sweet potato?

A1: Yes, canned puree works in a pinch. Skip roasting and add the puree directly when you would add roasted veggies. The flavor will be less caramelized but still tasty.

---

Q2: Is this soup freezer-friendly?

A2: Absolutely. Let it cool completely before transferring to freezer-safe containers. Thaw overnight in the fridge and reheat on the stovetop, adding broth if it thickens.

---

Q3: How spicy is this soup?

A3: It’s mildly spicy, with a gentle warmth from ginger and chili. You control the heat — reduce or omit chili flakes for a kid-friendly version, or add cayenne for extra fire.

---

Q4: Can I make it without a blender?

A4: Yes. Mash the vegetables with a potato masher for a rustic, chunky soup. It won’t be as silky, but the flavor will still shine.

---

Q5: What can I use instead of coconut milk?

A5: Heavy cream, half-and-half, cashew cream, or oat milk are all good options. If avoiding all creaminess, simply omit — the soup is still smooth and rich on its own.

---

Q6: How do I balance sweetness and spice?

A6: Add acid — lime juice, lemon juice, or a splash of vinegar — to cut the sweetness. A pinch of salt or a spoonful of tomato paste can also bring balance.

---

Q7: Can I add other vegetables?

A7: Definitely. Carrots, parsnips, or even apples add beautiful flavor. Just roast them along with the squash and sweet potato.
