Roasted Sweet Potato and Carrot Soup with Lentils

This roasted sweet potato and carrot soup with lentils mixes deep, caramelized veg with earthy lentils for a bowl that feels like a hug. It’s perfect for cool nights, weeknight dinners, or when you want a healthy, filling meal without fuss.

What makes this roasted root soup stand out

I love this recipe because it balances rich roast flavor with bright spices and a smooth finish. The roasting brings out natural sweetness in the potatoes and carrots, while lentils add body and protein. It’s seasonal and forgiving, which makes it great for cooks of all levels and for batch cooking. If you enjoy classic comfort soups, you might also like the savory notes in Italian sausage and potato soup as a different take on hearty bowls.

Reasons you’ll fall for this recipe

The taste lands between sweet and savory, with warm spices that don’t overpower. Texture plays an important role: creamy soup with tiny lentil bites keeps each spoonful interesting. The method is mostly hands-off once the vegetables are in the oven, so you get depth of flavor with a short active time. It’s ideal for meal prep, and the flavors actually meld as it rests.

Ingredients and how to swap them

Here’s a casual list of what you’ll need and why each item matters. Roast-first vegetables create caramel notes. Red or brown lentils thicken and add protein. Vegetable stock provides savory depth; coconut milk smooths the finish.

What you’ll need for this recipe

• 2 large sweet potatoes, peeled and cubed
• 4 large carrots, peeled and chopped
• 1 cup dried red or brown lentils, rinsed
• 1 medium onion, chopped
• 3 cloves garlic, smashed
• 1 tsp ground cumin, 1/2 tsp smoked paprika
• 4 cups vegetable stock
• 1/2 cup light coconut milk (optional for creaminess)
• 2 tbsp olive oil, salt and pepper to taste

Smart swaps for dietary needs

• Use yellow or red lentils for a faster cook.
• Swap coconut milk for oat or almond milk for a dairy-free option.
• For a lower-carb version, reduce potatoes and add more carrots.

Smart Variation (Optional)

Add a spoonful of plain yogurt and chopped herbs at serving for brightness.
