Ingredients You’ll Need

Each ingredient plays a role to create that beautiful balance of flavors and textures in this Easy Sweet Potato Lentil Soup Recipe. When shopping, look for fresh herbs if you can—they really make a difference—but dried will do in a pinch!

• Onion: Adds a natural sweetness and aromatic base when sautéed.
• Garlic: Brings depth and a little kick to the soup’s flavor profile.
• Carrot: Adds earthiness and slight sweetness, plus color.
• Celery stalk: Gives subtle savory sharpness and crunch if not overcooked.
• Sweet potato: The star of the show—its creamy texture and natural sweetness balance the lentils perfectly.
• Vegetable broth: Keeps everything juicy and flavorful without heaviness.
• Green lentils: Hold their shape well and add protein and fiber.
• Diced tomatoes (canned): A bit of acidity to brighten the soup and deepen the flavor.
• Bay leaves: Infuse subtle herbal notes during cooking.
• Fresh thyme, rosemary, sage: These herbs give the soup that warm, woodsy aroma and flavor.
• Chopped fresh kale: Adds bright color, nutrients, and a gentle bite.
• Salt and pepper: To taste—seasoning brings all the flavors alive.
• Vegan croutons (optional): Great for topping if you want texture and a bit of crunch.
• Pumpkin seeds (optional): Add nuttiness and more crunch when sprinkled on top.

Variations

I love how forgiving this Easy Sweet Potato Lentil Soup Recipe is, so I often switch things up depending on what I have in the fridge or my mood. You’re totally free to make it your own—experimenting with herbs, greens, or even swapping lentils for beans works beautifully.

• Swap the greens: I sometimes use baby spinach or Swiss chard instead of kale, especially when I want a milder green that cooks faster.
• Use different lentils: If green lentils aren’t available, brown or red lentils can be used, but note red lentils will break down more and make the soup thicker.
• Add a smoky twist: For fun, toss in a dash of smoked paprika or liquid smoke, which gives the soup an entirely new flavor dimension my family really enjoys.
• Spice it up: If you like heat, a pinch of cayenne or some chopped jalapeño peppers adds a nice kick without overpowering the sweet potatoes.

How to Make Easy Sweet Potato Lentil Soup Recipe

Step 1: Sauté the Veggies to Build Flavor

Start by heating 2 tablespoons of water or vegetable broth in a large pot over medium heat. Add the chopped onion, carrot, celery, and minced garlic. Stir these around and cook them until they’re soft and fragrant, usually about 3 to 4 minutes. Don’t rush this step—softening the vegetables really brings out their sweetness.

Once softened, add your cubed sweet potatoes and cook for another 5 to 6 minutes. Keep an eye on the pot and add a little water or broth as needed—this prevents the veggies from sticking or burning and keeps everything glistening.

Step 2: Add Lentils, Tomatoes, Herbs, and Broth

Pour in the vegetable broth, lentils, canned diced tomatoes (with their juices), bay leaves, and fresh herbs—thyme, rosemary, and sage. Give it all a good stir to combine everything evenly. You’re setting the stage for those flavors to mingle and develop as the soup simmers.

Bring the mixture to a gentle simmer, then lower the heat to medium-low, covering the pot with a lid. Let it cook for about 35 minutes or until the lentils are tender but not mushy. This part requires a bit of patience but check occasionally and stir so nothing sticks to the bottom.

Step 3: Finish With Greens and Season

Once the lentils are cooked, remove the pot from heat and stir in the chopped kale. The residual heat will gently wilt the greens—perfect for keeping their vibrant color and nutrients intact. Let the pot sit for about 5 minutes, then fish out the bay leaves.

Now, taste the soup and season with salt and pepper to your liking. This is the moment to adjust and really make the soup sing with flavor before serving.

Garnishes

I love topping this soup with vegan croutons for that satisfying crunch and a sprinkle of pumpkin seeds for extra nuttiness and texture. Sometimes I add a little drizzle of good-quality olive oil or a spoonful of vegan yogurt for creaminess—it just feels like a nice little fancy touch.

Side Dishes

This soup pairs beautifully with crusty bread or garlic naan if you want to dip, or a simple green salad for a fresh contrast. When my family digs in, we usually have a basket of whole-grain rolls nearby because who doesn’t like to mop up every last spoonful?

Creative Ways to Present

For special occasions, I’ve served this soup in rustic bread bowls, which impresses guests and naturally makes it a little more festive. You could also layer it with toasted nuts and a swirl of coconut cream to give it that “wow” factor if you’re entertaining but still want to keep it simple.

Make Ahead and Storage

Storing Leftovers

I usually store leftovers in airtight containers in the fridge, where this soup keeps really well for up to 4 days. The flavors actually deepen overnight, so it tastes even better the next day—making great packed lunches or quick dinners.

Freezing

This recipe freezes beautifully. I portion it out into freezer-safe containers or bags and freeze for up to 3 months. Just make sure to leave out the kale when freezing; add fresh greens after reheating to keep the texture fresh.

Reheating

When reheating, I warm it gently on the stove over medium-low heat, stirring occasionally. If it feels a bit thick, adding a little extra broth or water keeps the soup nice and spoonable without losing flavor.
