Silky Roasted Carrot Cumin Soup with Ginger

Jump to Recipe

Roasted carrot and cumin soup gets its depth from two steps most carrot soups skip: roasting the carrots until their edges caramelize, and blooming whole cumin in oil before the broth goes in. Both take an extra 10 minutes and change the flavor completely.

I roast the carrots at 425 F / 220 C alongside a quartered onion and a few unpeeled garlic cloves, which turns bitter garlic sweet and mellow. Once everything is fork-tender and browned at the edges, it goes into a pot with warmed cumin, ginger, and broth.

A blender does the rest. I finish the soup with a splash of coconut milk for body and a squeeze of lemon to cut the sweetness, a finishing touch much like this spiced roasted pumpkin and coconut soup, though heavy cream works the same way if you’re not keeping this dairy-free.

The soup keeps for a work week in the fridge and freezes well, so it’s worth doubling the batch.

Why You’ll Love This Recipe

• Caramelizes carrots for natural sweetness, no added sugar needed
• Comes together in about 60 minutes start to finish
• Freezes well for up to 3 months, easy meal prep
• Naturally vegan and gluten-free without tasting thin

Ingredient Notes

• carrots: Use standard orange carrots, not baby carrots. They roast drier and caramelize better at the edges.
• onion: Yellow onion roasts sweet. Red onion works too but can tint the soup slightly pink.
• garlic: Roasting whole cloves in their skins keeps them from burning while the carrots cook.
• ground cumin: Split it: half goes on the carrots before roasting, half blooms in oil for a deeper base flavor.
• fresh ginger: Adds warmth without heat. Swap in 1/2 tsp ground ginger if you don’t have fresh.
• vegetable broth: Use a broth you’d drink on its own since it’s half the soup’s liquid.
• coconut milk: Full-fat canned coconut milk gives body without dairy. Swap in 1/2 cup heavy cream if you prefer.
• lemon juice: Brightens the sweetness of the roasted carrots. Add it off heat so the flavor stays sharp.
• pepitas: Toasted pepitas add crunch against the smooth soup. Sunflower seeds work as a swap.

Ingredients

  

For the Roasted Vegetables

• 900 g carrots about 6 large, peeled and cut into 1-inch chunks
• 1 yellow onion large; cut into wedges
• 4 cloves garlic unpeeled
• 3 tbsp olive oil
• 1 tsp ground cumin
• 1 tsp kosher salt
• 1/2 tsp black pepper

For the Soup

• 1 tbsp olive oil
• 1 tsp ground cumin
• 1 tbsp fresh ginger grated
• 4 cups vegetable broth / 960 ml
• 1/2 cup coconut milk / 120 ml; full-fat, canned
• 1 tbsp lemon juice
• salt to taste
• 2 tbsp pepitas toasted, for garnish
• fresh cilantro small handful; for garnish, optional

Method

 

Roast the Vegetables

1. Heat the oven to 425 F / 220 C. Line a sheet pan 33 x 46 cm / 13 x 18 inch with parchment paper.
2. Toss the carrots, onion, and garlic cloves with 3 tbsp olive oil, 1 tsp cumin, salt, and pepper directly on the sheet pan.
3. Roast for 30 to 35 minutes, stirring once halfway through, until the carrots are fork-tender and caramelized at the edges.

Build and Blend the Soup

1. Once cool enough to handle, squeeze the roasted garlic cloves out of their skins and discard the skins.
2. Heat the remaining 1 tbsp olive oil in a 5-quart / 4.7 L Dutch oven over medium heat. Add the remaining 1 tsp cumin and the grated ginger, and cook for 30 seconds until fragrant.
3. Add the roasted carrots, onion, garlic, and vegetable broth. Bring to a simmer and cook for 8 to 10 minutes to let the flavors meld.
4. Blend the soup until smooth with an immersion blender, or in batches in a countertop blender filled no more than halfway.
5. Return the soup to the pot if needed. Stir in the coconut milk and lemon juice, then season with salt to taste.
6. Ladle into bowls and top with toasted pepitas and fresh cilantro.

Notes

• Roast carrots and onion on one sheet pan for less cleanup.
• Bloom cumin in oil before adding broth for deeper flavor.
• Blend in batches if using a countertop blender to avoid splatter.
• Stir coconut milk in off heat to keep it from separating.

Tips for Success

• Cut carrots into even 1-inch chunks, the same technique used for these spiced carrot and lentil fritters, so they roast at the same rate and don’t burn at the edges.
• Roast garlic cloves whole in their skins, then squeeze the soft cloves out before blending to avoid bitterness.
• Bloom the cumin in warm oil for 30 seconds before adding broth to wake up its flavor.
• Blend in batches if using a countertop blender, filling it no more than halfway to avoid hot soup splashing out.
• Thin the soup with extra broth if it firms up too much after chilling in the fridge.

Variations

• Swap coconut milk for heavy cream or Greek yogurt if you’re not keeping the soup dairy-free.
• Add 1 tsp smoked paprika with the cumin for a smokier, deeper flavor profile.
• Stir in a can of drained chickpeas after blending to turn the soup into a fuller meal.

Storage and Reheating

Roasted carrot and cumin soup keeps well in the fridge for 4 to 5 days in an airtight container. The flavor actually improves after a day, once the cumin and ginger settle into the broth.

Freeze the soup in individual portions for up to 3 months, just like this freezer-friendly smoky lentil and sweet potato curry. Leave the coconut milk out before freezing and stir it in fresh after reheating, since coconut milk can separate and turn grainy when frozen and thawed.

Reheat gently on the stovetop over medium-low heat, stirring occasionally, for 6 to 8 minutes until steaming. A microwave works too, in 90-second bursts, stirred between each.

Serving Suggestions

Roasted carrot and cumin soup eats like a full meal with crusty bread and a soft cheese like goat cheese or labneh on the side. A drizzle of olive oil and a few extra toasted pepitas on top add crunch.

For a heartier lunch, pair it with a grain salad or a simple green salad with a sharp vinaigrette to balance the soup’s sweetness.

It also works as a starter before a roast chicken or grilled fish dinner, served in smaller cups.

FAQ

Why is my roasted carrot and cumin soup thin instead of thick?

Thin soup usually means too much broth went in before blending, or the carrots weren’t roasted long enough to concentrate their natural sugars. Stick to the 4 cups of broth called for and add extra only after blending if needed. Roasting the carrots a full 30 to 35 minutes, until caramelized at the edges, also thickens the base naturally.

Can I use ground ginger instead of fresh ginger in this soup?

Yes, ground ginger works if that’s what you have on hand. Use 1/2 teaspoon of ground ginger in place of the 1 tablespoon of fresh, added at the same point when you bloom the cumin. Fresh ginger gives a brighter, sharper warmth, but ground ginger still rounds out the cumin nicely.

Can I freeze roasted carrot and cumin soup after adding the coconut milk?

You can, but the texture holds up better if you freeze the soup before stirring in the coconut milk. Coconut milk can separate and turn grainy after freezing and thawing. Freeze the base in portions for up to 3 months, then stir in fresh coconut milk after reheating on the stove.

What goes well with roasted carrot and cumin soup for a full meal?

Crusty bread and a soft cheese like goat cheese or labneh turn this soup into a full meal. A grain salad or a green salad with a sharp vinaigrette also balances the soup’s sweetness. It works as a starter too, served in smaller portions before roast chicken or grilled fish.

Is roasted carrot and cumin soup vegan and gluten-free?

Yes, this soup is naturally vegan and gluten-free as written, using vegetable broth and coconut milk instead of cream. Just double check your broth’s label since some brands add gluten-containing thickeners. Swap the coconut milk for heavy cream if you’re not keeping it dairy-free.

Why do you roast the carrots instead of boiling them for this soup?

Roasting concentrates the carrots’ natural sugars and caramelizes their edges, giving the soup a deeper, sweeter flavor than boiling ever does. Boiled carrots dilute into the water and taste flatter once blended. The 30 to 35 minutes in a 425 F / 220 C oven is worth the extra step.
