Ingredients You’ll Need
Each ingredient in this Lentil and Sweet Potato Soup Recipe works together to build layers of flavor and texture, from the aromatic vegetables to the warm spices. Picking fresh produce and quality spices will make a big difference here, so I always take a little extra time at the market.
- Olive oil: Helps soften the vegetables and infuses a subtle richness.
- Red onion: Adds sweetness and depth—don’t skip this base flavor!
- Carrots: Bring natural sweetness and vibrant color.
- Celery ribs: Offer a subtle crunch and aromatic lift.
- Bell pepper (optional): Adds a bright, slightly tangy note—red or green both work well.
- Garlic cloves: Thinly sliced for punchy, savory goodness.
- Paprika: Gives a warm, smoky undertone that ties the soup together beautifully.
- Cumin: Earthy and fragrant, it’s my secret weapon to boost flavor instantly.
- Coriander (optional): Adds a fresh citrusy note if you want an extra layer of complexity.
- Dry thyme (optional): Provides an herbal earthiness that complements the other spices.
- Salt and pepper: To taste—essential for balancing and brightening all the flavors.
- Diced tomatoes: In their juices, they add a subtle acidity and rich body.
- Sweet potatoes: Cubed to provide sweetness and creamy texture as they cook.
- Dry brown lentils: The protein-packed star that makes this soup filling and satisfying.
- Water: The cooking liquid that lets all ingredients meld together perfectly.

Variations
I love how adaptable this Lentil and Sweet Potato Soup Recipe is — it’s like a blank canvas that you can adjust based on what you have in your pantry or your mood. Over the years, I’ve tried a few tweaks that made it even more special.
- Adding Coconut Milk: I sometimes stir in a half cup of coconut milk at the end for a creamy, tropical twist that pairs beautifully with the spices.
- Spicy Kick: When I want a bit of heat, I toss in a pinch of red pepper flakes or diced jalapeño — be careful not to overpower the natural sweetness of the potatoes!
- Different Greens: Kale is a favorite, but I’ve also used Swiss chard or collard greens for a slightly different texture and flavor.
- Make It Hearty: For a non-vegan crowd, adding browned sausage or shredded chicken works great if you have some on hand.
How to Make Lentil and Sweet Potato Soup Recipe
Step 1: Sauté the Aromatics
Start by heating the olive oil in a large pot over medium-high heat. Toss in your chopped onion, carrots, celery, bell pepper if using, and garlic. Stir occasionally and let these soften and turn fragrant for about 3 minutes. This step builds the flavor base, so be patient and let the veggies sweat instead of brown—that’s the trick I learned to keep the soup bright and balanced.
Step 2: Spice It Up
Add your paprika, cumin, coriander, thyme (if using), salt, and pepper. Stir everything together for about a minute so the spices toast lightly. This releases their natural oils and really wakes up the dish. I always take this extra minute because it makes such a difference in flavor complexity.
Step 3: Combine Tomatoes, Sweet Potatoes, Lentils, and Water
Pour in the diced tomatoes with their juices, mixing them into the vegetables and spices. Add the cubed sweet potatoes and dry lentils, then pour in 8 cups of water. Stir gently to combine everything, then bring the pot to a boil over high heat.
Step 4: Simmer to Perfection
Once boiling, cover the pot with its lid and reduce heat to low so the soup simmers gently. Let it cook for 25 minutes, then check the sweet potatoes—they should be tender but not mushy. If they’re still a bit firm, pop the lid back on and let it simmer for another 5 minutes. I’ve found that overcooking the sweet potatoes can make the soup too thick and lose that perfect bite.
Step 5: Add Greens and Finish
Turn off the heat and stir in your chopped spinach or kale if you’re using it. Cover the pot again and let the greens wilt for about 5 minutes in the residual heat. Finally, squeeze in fresh lemon juice and sprinkle chopped parsley on top before serving. That bright citrus note is what pulls the whole soup together every time!
Pro Tips for Making Lentil and Sweet Potato Soup Recipe
- Perfect Lentil Texture: Brown lentils hold their shape well but remember to rinse them first to remove any dust or debris.
- Controlling Soup Thickness: If the soup gets too thick, just add a splash of water or broth to loosen it up without diluting flavors.
- Maximize Aroma: Toast your spices in the pot before adding liquids to give the soup a deeper, smokier flavor.
- Avoid Overcooked Sweet Potatoes: Keep an eye and gently poke them with a fork—they should be tender but intact to keep the soup’s texture balanced.
How to Serve Lentil and Sweet Potato Soup Recipe
Garnishes
My favorite garnishes for this soup are a sprinkle of fresh parsley and a drizzle of good-quality olive oil. Sometimes I add a spoonful of plain yogurt or a lemon wedge on the side for an extra pop of brightness. These little touches make it feel extra special and fresh every time.
Side Dishes
I usually serve this soup with some warm crusty bread or a side salad to round out the meal. For a heartier lunch, it pairs wonderfully with a simple grilled cheese sandwich or roasted veggies on the side to keep things light but satisfying.
Creative Ways to Present
For dinner parties, I like to serve this Lentil and Sweet Potato Soup Recipe in small bowls garnished with microgreens and a swirl of chili oil for a little heat. It’s also great served in hollowed-out mini pumpkins or bread bowls for a festive autumn look that always impresses guests.
Make Ahead and Storage
Storing Leftovers
I store leftovers in airtight containers in the fridge, and this soup keeps well for up to 4 days. The flavors actually deepen overnight, making it an excellent next-day meal that reheats beautifully.
Freezing
I often freeze portions in individual containers or freezer bags for quick meals later. Just be sure to cool the soup completely before freezing, and thaw it overnight in the fridge before reheating gently on the stove.
Reheating
Reheat the soup over low to medium heat, stirring occasionally. If it’s too thick after refrigeration, add a splash of water or broth to loosen it up without sacrificing flavor—this tip always helps me get that just-made taste again.
FAQs
-
Can I use red lentils instead of brown in this Lentil and Sweet Potato Soup Recipe?
Yes, you can substitute red lentils, but keep in mind that red lentils cook faster and tend to break down completely, resulting in a creamier soup texture. Brown lentils hold their shape better if you prefer a chunkier consistency.
-
Is this Lentil and Sweet Potato Soup Recipe suitable for meal prep?
Absolutely! This soup reheats beautifully and tastes even better after sitting overnight. It’s easy to portion out and freeze for quick meals throughout the week.
-
Can I make this Lentil and Sweet Potato Soup Recipe in a slow cooker?
Yes, you can adapt the recipe for a slow cooker by combining all ingredients (except spinach/kale, lemon, and parsley) and cooking on low for 6-8 hours or high for 3-4 hours. Add the greens and lemon juice just before serving.
-
Do I need to soak the lentils before cooking?
No soaking is required for brown lentils, which makes this soup quick and convenient. Just rinse them well before adding to cook dirt or dust off them.

Pantry Staples
- 2 tablespoons olive oil
- 1 (15-ounce) can diced tomatoes in their juices
- 1 cup dry brown lentils
- 8 cups water
Instructions
- Heat the oil and sauté vegetables: In a large pot with a lid, heat 2 tablespoons of olive oil over medium-high heat. Add the chopped onion, carrots, celery, bell pepper (if using), and garlic. Sauté for about 3 minutes until vegetables soften and become fragrant.
- Add spices and seasonings: Stir in 2 teaspoons of paprika, 1 tablespoon of cumin, 2 teaspoons coriander and 2 teaspoons thyme if using, along with salt and pepper to taste. Cook and mix for 1 minute to toast the spices gently, enhancing their flavors.

- Simmer the soup: Once boiling, cover the pot with the lid and reduce heat to a low simmer. Let the soup cook for 25 minutes. Check the doneness of sweet potatoes by poking with a fork. If they are still firm, cook for an additional 5 minutes but avoid overcooking to prevent them from breaking down into the broth.
- Add greens and let sit: When the sweet potatoes are tender, turn off the heat. Add chopped spinach or kale if using. Cover the pot again and let it sit for 5 minutes. This will gently wilt the greens without overcooking.
- Finish with lemon and parsley: Remove the lid, squeeze the juice of one lemon into the soup, and stir in the chopped parsley. Mix well and serve warm, enjoying a flavorful, nutrient-dense meal.
