Instructions to Make Hearty Lentil and Potato Soup

If you’re ready to create a soul-warming meal that feels like it’s been simmering all day (even if it hasn’t), this step-by-step guide will walk you through how to make Hearty Lentil and Potato Soup from start to finish. Each step includes helpful tips to simplify the process and maximize flavor, especially for busy weeknights when you just want something easy and comforting. Let’s get cooking—no stress, no fancy tools, just real food made delicious.

Step 1: Sauté the Aromatics for a Flavorful Base

In a large soup pot or Dutch oven, heat 2 tablespoons of olive oil over medium heat. Once the oil is shimmering (not smoking), toss in your diced onion, carrots, and celery. This trio is often called a mirepoix, and it’s the foundation of countless soups and stews.

Cook the vegetables for about 5–7 minutes, stirring occasionally, until the onions turn translucent and the carrots start to soften. You’re not just softening veggies here—you’re building the flavor base.

Step 2: Toast the Garlic and Spices for Depth

Now, stir in the minced garlic and let it cook for just about 60 seconds. You’ll know it’s ready when the kitchen smells like you could stop right here and just eat this.

Next, add in your spice blend: 1 teaspoon ground cumin, 1 teaspoon smoked paprika, ½ teaspoon dried thyme, and ½ teaspoon dried rosemary. Stir them in and let them toast with the veggies for another minute. This step brings out their essential oils and enhances the final taste of the soup, turning it from “pretty good” to “wait, you made this at home?”

If you don’t have smoked paprika, don’t sweat it—you can substitute with sweet paprika or a pinch of chipotle powder. For more help with swapping ingredients, our ingredient substitution guide in similar soup recipes will give you some great ideas.

Step 3: Add the Lentils, Potatoes, and Broth

Time to bring in the main players. Add 1½ cups of rinsed dried green or brown lentils (don’t skip the rinse—it removes debris and helps them cook more evenly), 3 diced potatoes, and 1 can (14.5 oz) of diced tomatoes with juices. Then pour in 8 cups of vegetable broth.

Give everything a good stir to combine, and season with salt and black pepper to taste. Bring the pot to a gentle boil over medium-high heat. Once it starts bubbling, reduce the heat to low, cover with a lid, and let it simmer for 30–40 minutes, stirring every so often.

During this time, the lentils will soften and absorb all those amazing flavors, while the potatoes become tender and creamy. If you’re craving more Mediterranean-style soups, check out our Mediterranean Orzo Soup for another cozy option.

Step 4: Stir in the Greens (Optional but Recommended)

If you’re using 2 cups of fresh spinach or kale, this is the time to toss them in—about 5 minutes before the soup finishes cooking. Stir gently so the greens wilt into the broth but still keep their vibrant color and nutrients.

Not a fan of leafy greens? You can skip them, or replace with chopped parsley, baby arugula, or even frozen peas. For a deeper dive on veggie alternatives that don’t compromise texture, browse our Creamy Cauliflower Soup for inspiration.

Step 5: Final Taste and Seasoning Check

Turn off the heat, then taste your soup. This is your moment to balance the flavors. Does it need a pinch more salt? A twist of black pepper? Maybe even a splash of lemon juice or balsamic vinegar to brighten it up?

Adjust to your liking, then give it one last stir. Garnish with fresh parsley just before serving for a pop of freshness. You can ladle it straight into bowls, pair it with crusty bread, or store it for a cozy lunch later in the week.

What to Serve with Hearty Lentil and Potato Soup

This soup plays well with others. A warm hunk of crusty bread? Yes, please. It’s perfect for dipping and soaking up all that brothy goodness. Want something a little extra? Pair it with Herbed Potato Rolls or a simple green salad dressed in lemon vinaigrette.

Craving something creamy and tangy on the side? Try a dollop of plain Greek yogurt or a spoonful of hummus and some pita chips.

The soup is hearty, but pairing it with the right side makes it feel like an intentional, put-together dinner—even if it only took 45 minutes to make.

Key Tips for Making Hearty Lentil and Potato Soup

First things first: don’t skip rinsing your lentils—it removes grit and helps them cook evenly. Dice your potatoes evenly so they cook at the same speed (no one wants a bite of mush next to a raw chunk). Let the soup simmer gently, not at a full boil, to keep the lentils from turning mushy. If you’re short on time, you can use canned lentils, but reduce the cooking time and add them halfway through.

Want more depth of flavor? Add a splash of balsamic vinegar or a squeeze of lemon juice at the end—it lifts everything up. Store-bought veggie broth works fine, but if you’ve got homemade broth or bouillon, go for it. Finally, if your soup is too thick, just splash in more broth or water. No stress, just soup.

Storage and Reheating Tips for Hearty Lentil and Potato Soup

This soup is the gift that keeps on giving. Store it in an airtight container in the fridge for up to 5 days. The flavors actually get better after a day or two—kind of like it’s been marinating in its own deliciousness. For freezing, let it cool completely, then transfer to freezer-safe containers.

It’ll keep for 3 months. Thaw in the fridge overnight, or just gently reheat on the stove with a splash of water or broth. Microwaving works too—cover loosely and stir halfway through to heat evenly. If you added greens, they might get a little softer after reheating, but it’s still tasty. Pro tip: make a double batch and freeze half. Future you will be so grateful.

FAQs

Can I use red lentils instead of green or brown?
Technically yes, but red lentils cook faster and break down more, so the texture will be mushier. Think creamy stew versus chunky soup.

Is this soup spicy?
Not at all. It’s smoky and savory. Want heat? Add a pinch of chili flakes or a splash of hot sauce.

Can I make it in a slow cooker?
Absolutely. Toss everything in (except greens and parsley), cook on low for 6–8 hours or high for 3–4. Stir in greens at the end.

What if I don’t have all the spices?
You can still make a flavorful soup with just cumin and paprika—or even just one of them. It’s super flexible.

Can I add meat?
Sure! Brown some sausage or shredded rotisserie chicken and stir it in before serving.
