Instant Pot Lentil Soup
This Instant Pot Lentil Soup is loaded with vegetables for a healthy, filling meal. This cozy recipe is perfect for a busy weeknight since it cooks quickly in the Instant Pot.
It took me a long time to finally buy a pressure cooker. I wasn’t sure it would be worth it since we don’t eat meat. But once I realized how much faster I could cook dried beans and lentils, I was hooked. I frequently make lentil soup and I love how quickly it cooks in a pressure cooker. I love that this soup is hearty and filling because lentils are a great source of protein and fiber. This is also a great budget-friendly recipe that can feed a large family.
Are Lentils Healthy?
Absolutely! Lentils are an excellent source of plant-based protein. They contain 9 grams of protein per 1⁄2-cup serving. They also contain fiber as well as vitamins and minerals. Plus, they’re an affordable source of protein. In fact, they’re one of the cheapest protein sources you’ll find at the grocery store. If you love lentils as much as I do, try my simple spiced lentils.
Ingredients and Substitutions
- Olive Oil– This helps enhance the flavors, but you can use additional broth to sauté the vegetables if you wanted to keep this recipe oil-free.
- Mirepoix– The onion, carrot, and celery are a traditional mirepoix base. If you’re missing an ingredient, check out this post for substitution options.
- Lentils– Be sure to use brown or green lentils for this recipe. Red lentils break down too quickly and won’t work in this recipe. If you’re looking for a way to use red lentils, try my Instant Pot Red Lentil Soup.
- Garlic– Don’t skimp on the garlic! If you don’t have fresh garlic you can use minced garlic. In a pinch, you can use 1 teaspoon of garlic powder.
- Tomatoes– I used canned diced tomatoes. You could substitute with fire-roasted diced tomatoes if you want to add a little smoky flavor.
- Bay leaf– A bay leaf adds a savory, slightly citrusy flavor. You can leave it out if you don’t have any.
- Cumin– This adds additional flavor with a hint of earthy spice.
- Thyme– Dried thyme adds a savory flavor. Substitute with 1/4 teaspoon dried rosemary if you don’t have any dried thyme.
- Vegetable Broth– I like Edward & Son’s “Not-Chicken” style broth, but any style broth is fine.
- Kale– Adding a little kale at the end of the cooking process is an easy way to give this soup a nutritional boost. Feel free to substitute with spinach.

This lentil soup is SO hearty and a great way to use up veggies in the fridge! I love how quickly it came together too, so much faster than stovetop.
