Ingredients

• 1 cup dried brown or green lentils, rinsed and picked over
• 4 cups low-sodium vegetable or chicken stock
• 1 medium onion, finely diced
• 2 cloves garlic, minced
• 1 large carrot, diced into small cubes
• 1 celery stalk, diced
• 2 tablespoons olive oil
• 1 teaspoon ground cumin
• 1/2 teaspoon smoked paprika (optional for a smoky note)
• Salt and freshly ground black pepper, to taste
• 1 tablespoon lemon juice or red wine vinegar
• 2 tablespoons chia seeds (optional—adds body and nutrition)
• 2 strips crisped pancetta or bacon, chopped (optional for a savory crunch)
• Fresh parsley or cilantro, chopped, for garnish

Step-by-Step Instructions

1. Heat a large pot over medium heat. Add olive oil. When shimmering, add the diced onion, carrot, and celery. Sauté until the edges start to color, about 5–6 minutes. The pan will smell sweet and toasty.
2. Add garlic, cumin, and smoked paprika. Stir for 30 seconds until aromatic. The spices bloom and fill the kitchen with warmth.
3. Toss in the rinsed lentils. Stir to coat them in the spiced oil for a minute. Pour in the stock. Bring to a simmer.
4. Reduce heat to medium-low. Cover and simmer until lentils are tender, 15–20 minutes depending on variety. Keep an eye on the liquid. You want a saucy, not dry, finish.
5. While the lentils cook, crisp the pancetta or bacon in a small skillet over medium-high heat. Cook until golden and crunchy. Drain on paper towels. This adds a juicy, smoky pop.
6. Once lentils are tender, use an immersion blender to puree about one-third of the pot for a creamy body. If you don’t have one, scoop a cup into a blender, pulse, and return it to the pot.
7. Stir in lemon juice and chia seeds if using. Chia thickens gently and gives a pleasant, almost velvety mouthfeel. Season with salt and pepper to taste.
8. Ladle into bowls. Top with the crispy pancetta or bacon and sprinkle with chopped herbs. The contrast of hot, silky soup and crunchy topping is irresistible.

Expert Tips

Rinse lentils well. This removes dust and little stones. It also helps them cook evenly. Quick, light rinses are fine.

Use the right stock. A good-quality stock deepens the flavor. If you use water, boost seasoning and aromatics slightly. Taste as you go.

Don’t over-blend. Blend only a portion for texture. All-blended can feel flat. Leaving some whole lentils keeps chew and interest.

Play with toppings. Toasted seeds, crispy shallots, or a dollop of yogurt all work. Try crunchy croutons for a saucy, crispy bite.

Storage

Cool the soup to room temperature before storing. Transfer to airtight containers. Refrigerate up to 4 days.

Freeze for longer storage. Use freezer-safe containers and leave headspace. The soup keeps well for 2–3 months in the freezer. Thaw overnight in the fridge before reheating.

When reheating, add a splash of stock or water. Lentils soak up liquid and can thicken. A quick simmer will loosen the texture and revive the flavors.

Variations

• Vegetarian: Skip the bacon and use mushroom or miso for umami. Add a splash of soy sauce for depth.
• Spicy: Add a pinch of red pepper flakes or a diced jalapeño with the aromatics for a lively kick.
• Herby Green: Stir in chopped spinach or kale at the end. It wilts in seconds and brightens the bowl.
• Smoky: Use smoked paprika and smoked sea salt for a campfire flavor without meat.
• Chunkier: Add diced potatoes or sweet potato with the lentils for heartier texture.

FAQ

Can I use red lentils? Yes. Red lentils cook faster and break down more. Reduce simmer time and expect a creamier, more stew-like texture.

Do I have to soak lentils? No. Lentils don’t require soaking. They cook quickly compared to other dried legumes. Just rinse them well.

Are chia seeds really necessary? They’re optional. Chia adds body and nutrition. If you don’t like the texture, skip them or use a cornstarch slurry to thicken.

Can I make this in a slow cooker? Absolutely. Use low heat for 4–6 hours. Add delicate herbs near the end. Slow cooking deepens flavor but can make lentils very soft.
