Ingredients for beet and sweet potato soup

Simple roots, bold flavors—this soup starts with roasted veggies and ends with velvety perfection.

The beets and sweet potatoes are the stars, so pick firm, vibrant ones—no soft spots or bruises. Trader Joe's has great organic options, but regular grocery store varieties work too. Roasting them first brings out their natural sweetness—don’t skip this step! If you’re short on time, you can microwave them first to speed up the process, but roasting gives the best depth of flavor. The yellow onion and garlic add a sweet, mellow base, so don’t rush chopping them—smaller pieces cook faster and blend smoother.

No fresh thyme? Dried works at one-third the amount. Want more smokiness? Swap smoked paprika for a pinch of liquid smoke (start with ½ tsp). Coconut milk can be swapped for cashew cream (soak 1 cup cashews overnight) or even a splash of almond milk, though the texture will be lighter. If you’re avoiding coconut, silken tofu blended in adds creaminess without dairy. For extra richness, stir in 1 tbsp tahini at the end—it’s packed with flavor and healthy fats.

This soup tastes even better the next day as flavors meld. Store in an airtight container in the fridge for 4-5 days or freeze for 3 months. For freezing, portion into single servings—just thaw and reheat with a splash of water. Garnish with toasted pumpkin seeds (toss with olive oil and roast at 350°F for 5-7 minutes) or a drizzle of olive oil and cracked black pepper. Leftovers reheat beautifully—just stir in a splash of water or broth if it thickens too much.

Step-by-step instructions for beet and sweet potato soup

This hearty soup comes together with simple steps and bold flavors.

Preheat your oven to 400°F and line a large baking sheet with parchment paper. Toss the 2 lbs sweet potatoes and 1.5 lbs beets with 1 tbsp extra-virgin olive oil, 1 tsp smoked paprika, and ½ tsp ground cinnamon. Spread them in a single layer—they should touch but not overlap. Roast for 30-35 minutes until tender and caramelized at the edges.

While they roast, dice the 1 whole yellow onion and mince the 4 cloves garlic. Toss these with the remaining 1 tbsp extra-virgin olive oil and add them to the baking sheet in the last 10 minutes of roasting. This ensures they get crispy and aromatic without burning. You'll know they're done when the vegetables are fork-tender and smell sweetly earthy.

Transfer the roasted vegetables to a large pot. Add 4 cups vegetable broth and 2 tbsp apple cider vinegar, then bring to a gentle boil over medium-high heat. Once boiling, reduce heat to medium-low and let it simmer for 10-12 minutes until the flavors meld and the vegetables break down slightly.

Use an immersion blender to purée the soup directly in the pot until completely smooth. If you prefer a chunkier texture, blend in batches and return only what you need. Stir in the 1 can coconut milk and ½ tsp ground black pepper, then taste and adjust seasoning with 1 tsp sea salt as needed. The soup should be rich, slightly tangy, and perfectly balanced.

Return the soup to a gentle simmer and stir in the ¼ cup fresh thyme leaves. Let it cook for an additional 3-5 minutes to infuse the thyme's bright aroma. Remove from heat and let it cool slightly—this helps the flavors settle and prevents the coconut milk from curdling.

Ladle the soup into bowls and garnish each serving with 1 tbsp toasted pumpkin seeds. Toast the pumpkin seeds in a dry skillet over medium heat for 3-4 minutes until golden and fragrant—just before serving. The contrast of crunchy seeds against the creamy soup adds texture and depth to every bite.

This soup tastes best when served warm, so I recommend making it fresh and enjoying it within 2-3 hours. If you need to reheat leftovers, warm gently over low heat on the stovetop, stirring occasionally, until heated through. Avoid microwaving to preserve the creamy texture.

Pair with crusty bread or a simple green salad to round out the meal. The earthy sweetness of the beets and sweet potatoes, balanced by the smoky paprika and bright thyme, makes this soup a comforting yet vibrant dish perfect for any season.

Dietary considerations for these flavors

Vegan-Friendly Foundation

This soup is naturally plant-based, relying on the earthy sweetness of sweet potatoes and beets for depth without any dairy or meat. The coconut milk adds creamy richness, while apple cider vinegar and smoked paprika balance flavors beautifully.

Every ingredient aligns with vegan principles, making it perfect for plant-based diets or anyone avoiding animal products. 🌱

Gluten-Free by Design

With no grains, flour, or wheat-based ingredients, this soup is inherently gluten-free. The broth is made from vegetable broth (ensure it's certified gluten-free if needed), and the spices and garnishes are naturally safe.

Even the pumpkin seeds and thyme are gluten-free staples. Always double-check labels on broth and spices if you're highly sensitive to cross-contamination.

Low-Sugar Adaptations

The natural sweetness of the vegetables means you won’t need added sugar, but if you prefer a touch more sweetness, try ½ tsp maple syrup or 1 tsp date syrup at the end.

For a tangier profile, increase the apple cider vinegar to 3 tbsp. The key is balancing the earthy flavors—start with small adjustments and taste as you go. 🍯

Allergen Considerations

This recipe is free from common allergens like dairy, eggs, and nuts (unless you add cashew cream). For coconut allergies, swap the coconut milk for silken tofu blended until smooth or a splash of unsweetened almond milk.

If nut allergies are a concern, skip the pumpkin seeds and opt for toasted sesame seeds instead. Always verify ingredient labels for hidden allergens.

Nutrient-Dense Boost

Packed with vitamin A from sweet potatoes and folate from beets, this soup is a nutritional powerhouse. The coconut milk adds healthy fats, while thyme and garlic contribute antioxidants.

It’s a hearty, satisfying meal that supports immune health, digestion, and energy levels—all without sacrificing flavor. Perfect for meal prep or cozy nights in! 💪
