About This Instant Pot Lentil Soup Recipe
This is THE recipe. The one I make when somebody sick, somebody is grieving, or somebody has a new baby.
It’s even the recipe I make when I’m sick myself, because it’s so easy that I can make it even when I’m not feeling well.
It’s the type of recipe where you don’t need to pre-cook anything, and there’s no extra steps at the end. There’s no opening the pot and adding anything halfway through.
It’s 100% as simple as chopping some sausage and a few veggies, putting everything in the Instant Pot, turning it on, letting it cook, and then grabbing a bowl and eating.
While my Slow Cooker Lentil Soup is also great, I actually love this Instant Pot version better. Even though it’s the exact same ingredients, the pressure cooking allows the flavors to really develop and meld together to create a richly flavored soup that tastes like it has cooked FAR longer than 15 minutes!
Ingredients for Lentil Soup Recipe Instant Pot Version
- green lentils – the star of the show, providing lots of fiber!
- smoked turkey sausage – adds a smoky, savory flavor and boost of protein.
- celery – adds a subtle aromatic flavor.
- garlic – deepens the flavor profile of the soup.
- carrots – adds a natural sweetness.
- leek – contributes a mild onion flavor without being overpowering.
- tomato paste – adds a big hit of umami goodness.
- curry powder, thyme, cumin, salt and pepper – the herbs and spices we’ll use to add a warm, complex flavor to this soup.
- chicken broth – provides the savory liquid base for the soup.
How to Make Instant Pot Lentil Soup
I am NOT a fan of Instant Pot recipes that require you to use the sauté function before you start the pressure cook. If I’m going to sauté something, I will probably just finish cooking whatever the item is on the stovetop or in my oven. No, if I’m using my Instant Pot, I want to set it and forget it. No pre-cooking, please!
In that spirit, all you do for this recipe is throw all of the ingredients into the pot and turn it on (same with my Instant Pot Butternut Squash Soup). While I was worried that skipping the sauté of the aromatics would lead to a less flavorful soup (I tested it both ways to compare), that wasn’t the case at all.
This soup is so richly flavorful that I would never guess it took just about a half hour to make. It truly tastes like it has simmered for hours.
How Long to Cook Lentil Soup in an Instant Pot?
I’ve found that 15 minutes on high pressure is just right! The aromatic vegetables are all tender, and the lentils are cooked through but not mushy, which I think is the sweet spot for any lentil soup.
Home Chef Tips for Pressure Cooker Lentil Soup
- Always rinse lentils under cold water and pick through them to remove any debris (rare but it happens) before using.
- Be sure to do the quick pressure release at the end of the cooking time rather than allow the pressure to naturally release, so the lentils don’t overcook.

Variations/Substitutions
- PROTEIN – Feel free to use cooked chicken or another type of sausage in place of the smoked turkey sausage. Or, omit the protein altogether.
- LENTILS – I like green lentils best for this soup, but brown or black lentils also work great.
- EXTRA VEGGIES – You can add additional vegetables like zucchini, bell peppers or spinach if you’d like.
