Ingredients Overview
The ingredients for this roasted sweet potato soup are simple, but their flavors deepen during the roasting and simmering process. Each one plays a role in developing the soup’s rich taste and smooth consistency.

• Sweet Potatoes: The star of the show. Roasting brings out their sweetness and adds a subtle smokiness. Use orange-fleshed varieties for the best texture and color.

• Onion: Adds savory depth and balances the natural sweetness of the potatoes. Yellow or white onions work best.

• Garlic: Roasted alongside the sweet potatoes for a mellow, nutty flavor that enhances the soup’s richness.

• Carrot: Boosts the natural sweetness and adds extra body to the soup.

• Vegetable or Chicken Broth: Forms the liquid base. Choose a low-sodium variety to control the salt level.

• Olive Oil: Used for roasting and sautéing. Adds healthy fat and richness.

• Spices: Cumin, paprika, cinnamon, and black pepper add warmth and gentle complexity.

• Salt: Brings all the flavors together. Season to taste after blending.

Optional finishers include coconut milk or cream for added richness, or a squeeze of lime for a bright contrast.

Step-by-Step Instructions

1. Roast the Vegetables
   Preheat the oven to 400°F (200°C). Peel and cube 2 large sweet potatoes (about 1.5 pounds total). Peel 1 carrot and cut into chunks. Slice 1 small onion into quarters. Leave 4 garlic cloves unpeeled.

Spread everything on a baking sheet. Drizzle with 2 tablespoons olive oil and toss to coat. Sprinkle with 1/2 teaspoon salt, 1/2 teaspoon paprika, and 1/4 teaspoon cumin. Roast for 25–30 minutes, flipping halfway, until sweet potatoes are golden and tender.

2. Sauté and Simmer
   In a large pot, heat 1 tablespoon olive oil over medium heat. Squeeze the roasted garlic cloves from their skins and add to the pot along with the roasted onion, carrot, and sweet potatoes. Stir gently.

Pour in 4 cups of vegetable or chicken broth. Add 1/4 teaspoon cinnamon and a pinch of black pepper. Bring to a boil, then reduce heat and simmer for 10–15 minutes to let the flavors meld.

3. Blend Until Smooth
   Use an immersion blender to puree the soup right in the pot, or transfer in batches to a blender. Blend until completely smooth and creamy.

If the soup is too thick, add more broth or a splash of water to reach your preferred consistency.

4. Finish and Adjust
   Taste and adjust with more salt or pepper as needed. For extra richness, stir in 1/2 cup canned coconut milk or a few tablespoons of cream before serving.

Common Mistakes to Avoid

• Don’t skip roasting—the flavor difference is huge.

• Blend thoroughly for a velvety finish; small lumps affect the texture.

• Avoid overseasoning early on—adjust once blended.

• Let soup cool slightly before blending in a standard blender to prevent splashes.

Tips, Variations & Substitutions

Tips

• Cut sweet potatoes and carrots evenly to ensure consistent roasting.

• For a silky smooth texture, strain the soup after blending if needed.

• Double the batch and freeze half for future meals.

Flavor Variations

• Spicy Kick: Add 1/4 teaspoon cayenne pepper or a chopped chili before blending.

• Thai-Inspired: Add a tablespoon of red curry paste and use coconut milk as the base.

• Autumn Herb Blend: Add thyme and rosemary for a more savory, earthy profile.

Substitutions

• Use butternut squash in place of sweet potatoes for a similar texture.

• Swap olive oil with avocado oil or ghee.

• Add a handful of red lentils for extra protein and fiber—just simmer until soft before blending.

Serving Ideas & Occasions
This soup is a standout for lunch or dinner during the colder months. Serve it as a first course for holiday meals or pair it with grilled cheese, garlic toast, or a wild rice salad for a comforting main.

Drizzle with a swirl of coconut cream, yogurt, or chili oil for visual appeal and flavor. A sprinkle of pumpkin seeds or fresh herbs adds crunch and color.

It’s also great for meal prep—store individual portions in the fridge or freezer and reheat when needed.

Nutritional & Health Notes
Sweet potatoes are a nutritional powerhouse—rich in fiber, beta-carotene, and vitamin C. Roasting them preserves nutrients while deepening their flavor.

This soup is naturally gluten-free, vegetarian, and can easily be made vegan by using vegetable broth and plant-based milk.

Adding a spoonful of coconut milk increases healthy fat content and makes it more filling, while keeping the soup dairy-free. The balance of complex carbs, vegetables, and spices makes it a wholesome, feel-good meal.
