This is perfectly cooked Instant Pot sausage and lentil soup with just enough Italian sausage to add rich, satisfying flavor and hints of fennel, rosemary, thyme and oregano.
Most often, I make lentil soup without meat. But sometimes, the meaty flavor of Italian sausage sounds just right in a bowl of lentil soup.
Instant Pot sausage and lentil soup is both hearty and healthy. A big pot of this sausage and lentil soup can feed your family dinner, and then lunch, or perhaps another dinner the following day. It's filling and nourishing and keeps well for days.
This is the type of soup that I call "weekend soup" because you can cook once, and eat it all weekend.
Especially when you have little kids, it's not like cooking on the weekend is much easier than cooking during the week. In some ways, I think weekend cooking is harder.
On the weekends, I'm done. I've been cooking all week and the last place I want to spend my time over the weekend is in the kitchen.
That's why I love a pot of weekend soup!
The prep for this soup is quick and easy. This is a basic dump-everything-in-one-pot soup recipe that cooks on it's own while you do something else.
What I like most about cooking lentil soup in the Instant Pot is the texture of the lentils. They're not too mushy, they're not too firm. As Goldilocks would say, this lentil soup is just right.
Can I Make this Instant Pot Lentil Soup Without Sausage?
Yes, this lentil soup is still delicious without sausage.
Can I Make Soup with Different Types of Sausage?
Yes, you can use your favorite sausage for this soup. You can also used sliced sausage rather than ground sausage. You can also just use plain, ground meat instead of flavored sausage.
How Do You Cook Lentils in an Instant Pot?
Cooking lentils in an Instant Pot is the easiest way cook this nutritious legume, because you can set the cooking time and the lentils will cook perfectly without supervision. Lentils, no matter how you cook them, don't need to be soaked ahead of time.
The texture of cooked lentils is determined by the type of lentil and how long you cook them.
The cooking times below are a good starting point and how I usually cook lentils, but it might take a few batches of lentils to find the perfect cooking time for your preference. If the lentils seem too soft, reduce the cooking time by 1 or 2 minutes the next time. Or, if the lentils seem too firm, add a minute or two of cooking time.
Instant Pot Brown and Green Lentils:
Softer lentils: 15 to 18 minutes
Soft lentils: 11 to 14 minutes
Firm lentils: 7 to 10 minutes
Instant Pot Red Lentils:
3 to 5 minutes: Tender
6 to 7 minutes: Tender/soft
8 to 9 minutes: Soft
9 to 12 minutes: Very soft/mushy
Instant Pot Black "Beluga" Lentils:
Soft lentils: 8 to 10 minutes
Firm lentils: 6 to 8 minutes
Instant Pot French "Puy" Lentils:
6 to 8 minutes
Brown and Green lentils are interchangeable and the most common and easiest to find in grocery stores. They are often used in soups, but can also be used in salads.
French or "Puy" lentils are a more expensive variety of green lentils. The texture is slightly firmer than regular green lentils.
Red and yellow lentils break down quickly and become soft and mushy. For this reason, they're usually used in soups with a creamy texture or in Indian dishes like daal.
Black or "beluga/caviar" lentils are a shiny black color and hold their shape very well. They have a texture that is more firm than brown and green lentils. For this reason they are often used in lentil salads, although they can be used in soup too.
