Ingredients

- 2 tablespoons olive oil
- 1 large onion, finely chopped
- 2 carrots, diced
- 2 celery stalks, diced
- 3 garlic cloves, minced
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika
- 1/2 teaspoon dried thyme
- 1 bay leaf
- 1 (14 oz) can diced tomatoes (or 1 cup fresh tomatoes, chopped)

Step-by-step instructions
- Prep the base: Heat the olive oil in a large pot over medium heat. Add the chopped onion, carrots, and celery. Cook, stirring occasionally, until the vegetables are soft and the onion is translucent, about 7–8 minutes.
- Add aromatics: Stir in the garlic, cumin, smoked paprika, and thyme. Cook for 1 minute until fragrant.
- Combine lentils and liquids: Add the rinsed lentils, diced tomatoes, bay leaf, and vegetable broth. Bring to a gentle boil.
- Simmer: Reduce heat to low, cover, and simmer for 25–30 minutes until the lentils are tender but still hold their shape. Stir occasionally and add a splash of water or broth if the soup becomes too thick.
- Finish and season: Remove the bay leaf. Stir in lemon juice (if using), and season with salt and pepper to taste. For a creamier texture, use an immersion blender to puree about one-third of the soup, or transfer a cup to a blender and return it to the pot.
- Serve: Ladle into bowls and garnish with chopped parsley or cilantro. A drizzle of olive oil or a spoonful of plain yogurt (or a dairy-free alternative) is lovely.
For a heartier, protein-rich bowl, try pairing this soup with warm gluten-free rolls or a crisp salad; for inspiration, check this savory gluten-free chicken noodle soup recipe style.
Tips for success
- Rinse lentils well and pick out small stones or debris.
- Use low-sodium broth so you can control salt levels as it reduces.
- If the soup tastes flat after simmering, a squeeze of lemon or a splash of vinegar brightens the flavors.
- Cook lentils until tender but not mushy for the best texture.
- For extra depth, sauté a splash of tomato paste with the vegetables before adding broth.
Beginners may find it useful to prep all vegetables before turning on the stove — a mise en place habit that makes cooking more relaxed and enjoyable. If you like a stronger onion flavor, caramelize the onion longer and follow ideas from this rich French onion soup mix approach for building layers of taste.
Possible variations
- Gluten-free: This Vegetarian Lentil Soup is naturally gluten-free when you use gluten-free broth and avoid wheat-based thickeners. Serve with gluten-free croutons or bread.
- Streusel-style crunchy topping: For a fun twist, make a savory streusel using gluten-free oats, chopped walnuts, a pinch of smoked paprika, olive oil, and a little salt. Toast in a skillet until golden and sprinkle over bowls for crunch.
- Spicier version: Add 1/4–1/2 teaspoon red pepper flakes or a diced jalapeño with the onions.
- Creamy coconut variation: Stir in 1/2 cup coconut milk at the end for a silky, subtle-sweet finish.

Storage recommendations
- Refrigerate: Cool the soup to room temperature, transfer to airtight containers, and refrigerate for up to 4 days.
- Freeze: Freeze in portions for up to 3 months. Thaw overnight in the fridge before reheating.
- Reheating: Gently reheat on the stovetop over low heat, adding a splash of broth or water if it has thickened. Avoid boiling vigorously to preserve texture.

FAQs
Q: Can I use red lentils instead of brown or green?
A: Yes. Red lentils cook faster and tend to break down into a creamier texture, so reduce simmering time to 15–20 minutes and check frequently.
Q: How can I make the soup thicker without pureeing?
A: Mash a portion of the cooked lentils against the pot with a spoon, or add a small potato diced and cooked with the lentils to naturally thicken the broth.
Q: Is lentil soup a good source of protein?
A: Absolutely. Lentils are high in plant-based protein and fiber, making this soup a filling, nutritious meal for vegetarians and omnivores alike.
Q: Can I freeze this soup with added garnishes like herbs or yogurt?
A: It’s best to freeze plain soup without fresh herbs, yogurt, or dairy garnishes. Add fresh herbs and any yogurt or creamers when reheating and serving for best texture and flavor.
