This Instant Pot Lasagna Soup is cheesy, hearty, and done in minutes! It’s a cozy weeknight dinner your family will love.
I don’t know what the weather’s like in your neck of the woods, but here it’s definitely soup season. It’s chilly, it won’t stop snowing, and I really just want to stay inside and eat lots and lots of soup. And the Instant Pot? Well, it just happens to be the best way to make soup when you want to get it on the table fast!
Instant Pot Lasagna Soup Recipe
I love this Instant Pot Lasagna Soup because it’s a little bit different from other lasagna soup recipes I’ve had: it’s vegetarian! It swaps the ground beef for brown lentils. My kids were definitely skeptical about this, but once they gave it a try, they were believers: lentils are tasty! They have an earthy flavor and heartiness that make them a great addition to this cheesy, tomato-y Instant Pot Lasagna Soup.
I highly recommend making a batch of homemade garlic bread to serve with your lasagna soup—the two are just made for each other! Of course, a loaf of French bread will work just fine, too. As long as you have some good crusty bread to soak up all the flavorful broth, you’ll be set.
Ingredients
See recipe card below this post for ingredient quantities and full instructions.
- Olive oil
- Onion – Use a yellow or white onion.
- Dry brown lentils – Don’t substitute another type of lentil; they cook differently and will change the cooking time and consistency of your lasagna soup.
- Oregano
- Garlic powder
- Diced tomatoes
- Tomato paste
- Vegetable broth – If you prefer a slightly thinner soup, add another cup of broth.
- Lasagna noodles – Use the traditional kind, not the no-bake ones.
- Fresh mozzarella – You can use shredded mozzarella instead if you prefer.
Variations
- Vegetable Lasagna Soup – Add mushrooms, zucchini, green beans, or your favorite vegetables.
- Extra-Cheesy Lasagna Soup – Top each portion with a dollop of ricotta and grated Parmesan.
