Step-by-Step Instructions
Ready to get cooking? Follow these simple steps for a delicious, no-fuss meal.
Step 1: Sauté the Aromatics
Turn your Instant Pot to the “Sauté” function. Add the olive oil and let it heat for about 30 seconds. Toss in the diced onion, carrots, and celery. Sauté for 3–4 minutes, stirring occasionally, until the vegetables begin to soften and the onions turn translucent. Add the minced garlic and cook for another 30 seconds—just until fragrant. This step builds the flavor foundation of your soup.
Step 2: Add Spices and Lentils
Sprinkle in the cumin, smoked paprika, and turmeric (if using). Stir for about 30 seconds to toast the spices—this enhances their aroma and flavor. Then add the rinsed lentils, diced tomatoes (with juices), vegetable broth, and bay leaf. Give everything a good stir to combine.
Step 3: Pressure Cook
Secure the lid on the Instant Pot and set the valve to “Sealing.” Select “Manual” or “Pressure Cook” on high pressure for 10 minutes. The Instant Pot will take about 10–15 minutes to come to pressure, so total time will be around 25–30 minutes.
Step 4: Natural Release
Once the cooking time is up, allow the pressure to release naturally for 10–15 minutes. Then carefully turn the valve to “Venting” to release any remaining steam. Open the lid away from your face to avoid steam burns.
Step 5: Finish and Serve
Remove the bay leaf. If you’re adding leafy greens like spinach or kale, stir them in now and let the residual heat wilt them. For a brighter flavor, squeeze in some fresh lemon juice. Taste and adjust seasoning with salt and pepper. For a creamier texture, stir in coconut milk or blend a portion of the soup with an immersion blender.
Serve hot with crusty bread, a dollop of yogurt, or a sprinkle of fresh herbs like parsley or cilantro.
Tips for the Best Lentil Soup
Even the simplest recipes benefit from a few insider tips. Here’s how to make your lentil soup recipe Instant Pot version truly exceptional.
Choose the Right Lentils
Not all lentils are created equal. Green and brown lentils hold their shape well during pressure cooking, making them ideal for soup. Avoid red or yellow lentils—they break down too much and turn mushy. French green (Puy) lentils are a great choice if you want a firmer texture.
Don’t Overcook
While the Instant Pot is forgiving, overcooking can lead to a soupy, rather than hearty, consistency. Stick to the 10-minute cook time. If you prefer softer lentils, you can add 1–2 minutes, but avoid going over.
Boost the Flavor
For extra depth, try sautéing a tablespoon of tomato paste with the onions. You can also add a Parmesan rind during cooking—it melts into the soup, adding umami richness. Finish with a drizzle of high-quality olive oil or a splash of balsamic vinegar for a gourmet touch.
Make It Creamy (Without Dairy)
Want a silky-smooth texture without heavy cream? Use an immersion blender to puree about half the soup, then stir it back in. Alternatively, add a spoonful of tahini or a splash of coconut milk for creaminess and richness.
Freeze for Later
This soup freezes beautifully. Let it cool completely, then transfer to airtight containers or freezer bags. It keeps for up to 3 months. Thaw overnight in the fridge and reheat on the stove or in the microwave.
Serving Suggestions and Pairings
A great soup deserves great company. Here are some ways to elevate your meal:
Toppings and Garnishes
- Fresh herbs: chopped parsley, cilantro, or dill
- A dollop of Greek yogurt or sour cream
- Crumbled feta or goat cheese
- Croutons or toasted seeds (like pumpkin or sunflower)
- A swirl of olive oil or chili oil
Side Dishes
Serve with warm crusty bread, garlic toast, or a simple green salad. For a heartier meal, pair with a side of quinoa or brown rice. This lentil soup recipe Instant Pot style is also delicious alongside a grilled cheese sandwich for a cozy comfort food combo.

A crisp white wine like Sauvignon Blanc complements the earthy flavors. For a non-alcoholic option, try sparkling water with a slice of lemon or a warm cup of herbal tea.

Frequently Asked Questions
What’s the best type of lentil for Instant Pot soup?
Green or brown lentils work best because they hold their shape during pressure cooking. Red lentils can become too soft.
Can I double this recipe?
Yes, but don’t fill the Instant Pot more than halfway. Double the ingredients and increase cook time by 2–3 minutes.
Why is my lentil soup too watery?
This can happen if the lentils overcook or if too much liquid is used. Try simmering on “Sauté” to reduce, or blend part of the soup to thicken it.
Can I add meat to this soup?
Absolutely. Add cooked sausage, diced ham, or shredded chicken at the end for extra protein and flavor.
Is this soup high in protein?
Yes! One cup of cooked lentils provides about 18 grams of plant-based protein, making this soup very filling.
Can I cook this soup on the stovetop instead?
Yes, but it will take about 45–60 minutes. Simmer lentils and vegetables in broth until tender, stirring occasionally.
