This hearty lentil and vegetable stew is a satisfying vegetarian recipe using brown or green lentils, carrots, celery, tomatoes, and leafy greens in a gently spiced broth. It cooks in one pot, needs no soaking, and finishes with lemon for a bright, savory flavor that works for a weeknight dinner or make-ahead lunch.
Ingredients
- 1 tablespoon olive oil (15 ml)
- 1 medium yellow onion, diced (about 150 g)
- 2 medium carrots, diced (about 180 g)
- 2 celery ribs, diced (about 100 g)
- 3 garlic cloves, finely chopped (about 9 g)
- 2 tablespoons tomato paste (30 g)
- 1 teaspoon ground cumin (2 g)
- 1 teaspoon smoked paprika (2 g)
- 1 teaspoon dried thyme (1 g)
- 1½ cups brown or green lentils, rinsed and drained (300 g)
- 1 can diced tomatoes, including the juices (14½ ounces/411 g)
- 6 cups low-sodium vegetable broth (1.4 L)
- 1 bay leaf
- 1 teaspoon fine salt (6 g), plus more to taste
- ¼ teaspoon freshly ground black pepper (about 0.5 g), plus more to taste
- 3 packed cups baby spinach (about 90 g)
- 2 tablespoons fresh lemon juice (30 ml)
- 2 tablespoons chopped fresh parsley (about 8 g), optional
Instructions
- Prepare the lentils and vegetables. Pick through the lentils for any small stones or damaged pieces, then rinse them in a fine-mesh strainer under cool running water and drain well. Brown and green lentils do not need soaking for this stew. Dice the onion, carrots, and celery into small, similar-sized pieces so they soften at a similar rate; finely chop the garlic.
- Soften the vegetables. Heat the olive oil in a large, heavy pot or Dutch oven over medium heat. Add the onion, carrots, and celery and cook for 7 to 8 minutes, stirring occasionally, until the onion is translucent and the carrots are beginning to soften. If the vegetables start to stick or brown too quickly, lower the heat and add a tablespoon of water rather than extra oil.
- Toast the seasonings. Stir in the garlic, tomato paste, cumin, smoked paprika, and thyme. Cook for 2 minutes, stirring constantly so the garlic does not scorch. The tomato paste should darken slightly and coat the vegetables; this short cooking step gives the broth a deeper, rounder flavor.
- Add lentils and simmer. Tip in the rinsed lentils, diced tomatoes and their juices, vegetable broth, bay leaf, salt, and pepper. Stir, scraping the bottom of the pot to loosen any browned tomato paste. Bring the mixture to a boil, then reduce the heat to maintain a gentle simmer. Partially cover the pot and cook for 35 minutes, stirring every 10 minutes. Keep the bubbles gentle: a hard boil can split lentils and make the vegetables mushy before the center of the lentils is tender.
- Check the texture. Taste a few lentils from different parts of the pot. They should be tender all the way through but still hold their shape. If they remain firm, continue simmering and check again after 5 minutes; lentil age and variety can affect cooking time. If the stew has become thicker than you like, stir in hot water or broth a little at a time.
- Finish and serve. Remove and discard the bay leaf. Stir in the spinach and cook for 1 to 2 minutes, just until wilted. Turn off the heat, add the lemon juice, and taste the stew. Adjust salt, pepper, or lemon as needed, then scatter parsley over the top if using. Let it stand for 2 to 3 minutes so the broth settles before ladling into bowls.
Tips
- Choose the right lentils. Brown and green lentils are best here because they stay relatively intact in a stew. Red or yellow split lentils cook faster and break down into a softer, thicker texture, so they are not a direct swap; if using them, reduce the simmer time and check frequently.
- Keep the simmer gentle. A steady, low simmer cooks lentils evenly. If the broth is bubbling vigorously, lower the burner. Stirring every 10 minutes helps prevent sticking, but stirring constantly can break up the lentils and vegetables.
- Adjust salt after checking the broth. Vegetable broths vary in saltiness, and canned tomatoes can be seasoned too. Starting with the measured teaspoon and correcting at the end makes it easier to avoid an overly salty pot. Use unsalted broth if you want more control.
- Use greens that suit your timing. Baby spinach needs only a minute or two at the end. Chopped kale or collards are sturdier; add them for the final 8 to 10 minutes so they soften. If your greens are especially tough, remove thick stems before chopping.
Serving Suggestions
Serve the stew hot in wide bowls with crusty bread, warm pita, or toasted sourdough for dipping into the tomato-lentil broth. For a more substantial meal, spoon it over cooked brown rice, barley, couscous, or a baked potato. If serving it over a grain, keep the stew slightly brothy; add a splash of hot water or vegetable broth just before serving if it has thickened while standing.
A simple side salad of crisp greens, cucumber, and a tart vinaigrette balances the stew’s soft vegetables and earthy lentils. A spoonful of plain yogurt or a dairy-free yogurt alternative adds a cool, creamy contrast, while extra lemon wedges let each person sharpen the flavor to taste. For a dairy-free meal, check the yogurt label or leave it off; the stew itself contains no dairy.
Variations
Make it curry-style: Replace the cumin, smoked paprika, and thyme with 1 tablespoon curry powder (about 6 g) and add ½ teaspoon ground turmeric (about 1 g). For a creamier broth, stir in ½ cup coconut milk (120 ml) during the final 5 minutes, then taste for salt and lemon. Coconut milk makes the stew richer and slightly sweet, so the lemon is especially helpful.
Add more vegetables: Stir in 1 diced red bell pepper (about 150 g) with the carrots, or add 1 cup diced zucchini (about 150 g) for the final 15 minutes so it does not turn too soft. A cup of frozen peas can go in during the last 5 minutes. These additions change the balance of the pot, so add a little broth if it becomes too crowded or thick.
Make it smoky or spicy: Use hot smoked paprika, or add ¼ teaspoon crushed red pepper flakes (about 0.5 g) with the other seasonings. For a deeper smoky note, use ½ teaspoon smoked paprika and ½ teaspoon regular paprika instead of a full teaspoon of smoked paprika. Add heat cautiously and let the finished stew sit for a minute before deciding whether it needs more.
Use a different broth base: Mushroom broth makes the stew earthier, while a mild vegetable stock keeps the tomato and herbs more prominent. If you do not have broth, use 6 cups water (1.4 L) and add an extra pinch of salt and a little more thyme, then adjust seasoning at the end. Water works, but the flavor will be less rounded.
Storage and Reheating
Cool leftovers promptly and refrigerate them within 2 hours of cooking in shallow, airtight containers. The stew keeps for 3 to 4 days in the refrigerator. It will thicken as the lentils absorb broth, so add a splash of water or vegetable broth when reheating. For the best texture, store bread and toppings separately rather than mixing them into the pot.
Reheat a portion in a saucepan over medium-low heat, stirring occasionally, until steaming hot throughout; add broth as needed to loosen it. For food safety, USDA FSIS recommends reheating leftovers to 165°F (74°C), checked with a food thermometer. In a microwave, cover loosely, heat in short intervals, and stir between intervals so the center warms evenly; check the temperature in more than one spot.
To freeze, cool the stew and transfer it to freezer-safe containers, leaving a little room for expansion. Freeze for up to 3 months for best quality. Thaw overnight in the refrigerator and reheat as described above. Spinach can become softer after freezing, but the flavor remains good; if you know you plan to freeze portions, you can freeze the stew before adding the spinach and stir fresh greens in while reheating.
Frequently Asked Questions
Do I need to soak lentils before making this stew?
No. Brown and green lentils cook without soaking, so rinsing and checking them for debris is enough. Soaking can shorten cooking time, but it also makes the timing less predictable for this recipe. If your lentils are unusually old or still firm after the stated simmer, simply cook them longer and add a little extra broth if needed.
Can I use canned lentils instead of dried lentils?
Yes, but add them near the end because canned lentils are already cooked. Use about 3½ to 4 cups drained and rinsed canned lentils (roughly 600 to 700 g, depending on the brand). Simmer the vegetables, tomatoes, and broth for about 20 minutes first, then add the lentils and cook for 5 to 10 minutes to warm them through. The stew may be slightly less thick, so simmer uncovered briefly if you want to reduce the broth.
Why are my lentils still firm after 35 minutes?
Cooking time varies with the lentil variety, how old the lentils are, and how steadily the pot has simmered. Continue cooking in 5-minute increments and taste a lentil each time. Acidic ingredients such as tomatoes can slow softening, which is why this recipe cooks the lentils in the tomato broth from the start; older lentils may simply need longer. Keep the liquid at a gentle simmer and top it up if it reduces too much.
Can I make the stew ahead of time?
Yes. The flavors meld as the stew rests, and it reheats well, making it useful for meal prep. Cook it fully, cool it promptly, and refrigerate it in portions within 2 hours. When reheating, loosen it with broth or water and bring it to 165°F (74°C). If you want the spinach to stay brighter, cook the stew ahead without it and add the spinach during reheating.
Is this lentil stew gluten-free and vegan?
The listed ingredients are vegan and naturally gluten-free, but packaged vegetable broth and seasonings can vary. Check their labels if you are cooking for someone who needs to avoid gluten or animal-derived ingredients. Serve with gluten-free bread or rice as needed, and skip the optional yogurt topping unless you choose a plant-based alternative.
