Ingredients
| Ingredient | Amount |
|---|---|
| Olive oil | 2 tablespoons |
| Large onion, diced | 1 |
| Garlic cloves, minced | 3 |
| Large carrots, diced | 2 |
| Celery stalks, diced | 2 |
| Dried green or brown lentils, rinsed | 1½ cups |
| Medium potatoes, diced | 3 |
| Diced tomatoes with juices | 1 can (14.5 oz) |
| Vegetable broth | 8 cups |
| Ground cumin | 1 teaspoon |

| Dried thyme | ½ teaspoon |
| Dried rosemary | ½ teaspoon |
| Salt and black pepper | To taste |
| Fresh spinach or kale (optional) | 2 cups |

Instructions
Step 1: Sauté the Aromatics
In a large pot, heat the olive oil over medium heat until it shimmers slightly. Add the diced onion, carrots, and celery, then sauté for about 5 minutes, stirring occasionally. You’ll know they’re ready when the vegetables begin to soften and the onion turns translucent with those lovely golden edges.
Step 2: Add Garlic and Spices
Stir in the minced garlic and cook for another minute, just until your kitchen smells absolutely amazing. Then add the cumin, smoked paprika, thyme, and rosemary, stirring everything together. Toasting the spices briefly with the vegetables helps release their essential oils and enhances the depth of flavor in your hearty lentil and potato soup.
Step 3: Simmer the Soup
Add the rinsed lentils, diced potatoes, canned tomatoes (including all those flavorful juices), and vegetable broth. Season generously with salt and black pepper to taste. Bring the mixture to a boil, then reduce the heat to low and cover the pot.
Let it simmer for 30–40 minutes, stirring occasionally, until the lentils are tender and the potatoes practically melt on your spoon. The soup should thicken naturally as the lentils release their starches.
Step 4: Add Greens (Optional)
If using spinach or kale, stir it in during the final 5 minutes of cooking. The greens will wilt beautifully and add a pop of color while preserving their nutritional value. I love how the vibrant green contrasts with the earthy tones of the lentils and potatoes.
Step 5: Final Seasoning
Taste the soup and adjust the seasoning as needed—sometimes a pinch more salt or a crack of fresh pepper can really bring out all those Mediterranean flavors. Serve hot, garnished with fresh parsley for a burst of freshness that makes each bowl feel special.
Substitutions
Lentil Options
Green or brown lentils work beautifully in this potato and lentil soup because they hold their shape during cooking. Red lentils will break down completely and create a creamier texture, which some families actually prefer for a smoother consistency.
Potato Varieties
Yukon Gold potatoes give you a buttery, creamy texture, while Russets create a fluffier, more starchy base. Sweet potatoes add a subtle sweetness that pairs wonderfully with the cumin and smoked paprika if you’re feeling adventurous.
Broth Alternatives
Vegetable broth keeps this naturally gluten-free and vegetarian, but chicken broth adds extra depth if that’s what you have on hand. Just check labels to ensure your broth is certified gluten-free if you’re cooking for someone with celiac disease.
Greens Substitution
No spinach or kale? Swiss chard, collard greens, or even frozen spinach work perfectly in this hearty lentil and potato soup. Just thaw and squeeze out excess water from frozen greens before adding them to the pot.
Troubleshooting
Soup Too Thick
If your potato and lentil soup becomes thicker than you’d like, simply add more vegetable broth or water, about ½ cup at a time, until you reach your preferred consistency. The lentils and potatoes absorb quite a bit of liquid as they cook, especially if the soup sits for a while.
Lentils Still Hard
Old lentils take longer to cook, so if yours aren’t tender after 40 minutes, keep simmering and add more broth as needed. Always rinse lentils before cooking to remove any debris, and avoid adding acidic ingredients like tomatoes at the very beginning, as acid can toughen lentils.
Bland Flavor
Well… if your soup tastes flat, you probably need more salt than you think. Don’t be shy—taste as you go and season in layers. A splash of lemon juice or red wine vinegar at the end brightens everything up and makes the flavors pop.
Potatoes Falling Apart
If you prefer chunky potato pieces in your hearty lentil and potato soup, cut them slightly larger and add them halfway through cooking. Waxy potatoes like red or fingerling varieties hold their shape better than starchy Russets.
Storage
This Mediterranean diet recipes winter staple stores beautifully in airtight containers in the refrigerator for up to 5 days. The flavors actually deepen and improve overnight, making leftovers even more delicious than the first day. You can also freeze portions in freezer-safe containers for up to 3 months—just thaw in the fridge overnight and reheat gently on the stovetop.
Serving Suggestions
Serve this hearty lentil and potato soup with crusty gluten-free bread for dipping, or pair it with a simple side salad for a complete meal. A dollop of Greek yogurt or a drizzle of good olive oil on top adds richness and makes each bowl feel restaurant-worthy. This soup is perfect for Sunday meal prep or serving a crowd during the holidays—it’s one of those dishes that everyone loves, whether they’re gluten-free or not.
Variations
Creamy Lentil Soup
For an ultra-creamy version, use an immersion blender to partially blend the soup, leaving some chunks for texture. This creates a velvety base while keeping the hearty elements intact—kids especially love this smoother consistency.
Spicy Kick
Add ½ teaspoon of red pepper flakes with the other spices, or stir in a spoonful of harissa paste for a North African twist. The warmth complements the earthy lentils beautifully without overwhelming the other Mediterranean flavors.
Italian-Style
Swap the cumin for Italian seasoning and add a parmesan rind while simmering for incredible depth. Remove the rind before serving, and you’ll have a potato and lentil soup that tastes like it’s been simmering in an Italian grandmother’s kitchen all day.
Sausage Addition
Brown some Italian sausage (check for gluten-free varieties) before adding the aromatics for a heartier, protein-packed version. This turns the soup into a true one-pot meal that even the pickiest eaters will devour.
Dairy-Free & Vegan
This hearty lentil and potato soup is naturally dairy-free and vegan as written. Just skip any optional yogurt garnish and use olive oil for richness instead—it’s perfect for serving guests with different dietary needs.
Hearty Lentil and Potato Soup FAQs
Are lentils good in potato soup?
Absolutely! Lentils add protein, fiber, and a wonderful earthy flavor that complements potatoes perfectly. They also help thicken the soup naturally as they cook, creating that satisfying, hearty texture we all crave in a comforting bowl.
Can you eat lentils and potatoes together?
Yes, lentils and potatoes are a classic combination in Mediterranean and Middle Eastern cooking. Together they create a complete, balanced meal with complex carbohydrates, plant-based protein, and plenty of vitamins and minerals—plus they’re both naturally gluten-free and budget-friendly.
What are the common mistakes in making lentil soup?
The biggest mistakes are adding salt or acidic ingredients too early (which toughens lentils), not rinsing lentils before cooking, and underseasoning at the end. According to expert cooking science resources, lentils cook best in well-seasoned broth added after they’ve started to soften.
Is lentil soup healthy or fattening?

Pre-boiling is unnecessary and actually reduces the flavor since the lentils won’t absorb all those delicious seasonings.
