That’s right! Everything you love about lasagna is put together in a warm and comforting bowl for you to devour. You can make it using leftover lasagna strips or the broken lasagna pieces that you don’t use.

Why We Love Instant Pot Lasagna Soup?

The instant pot lasagna soup is quite a quick and easy recipe, and it is vegetarian recipe you’ll love! However, if you’re vegan you can swap out the pasta for vegan friendly pasta, and the leave of the mozzarella.

How truly easy is this recipe? All you need is to sauté the onion until it turns translucent, add all the other ingredients to the instant pot, and let it do the pressure cooking.

For this recipe, we’re using brown lentils in place of ground meat and vegetable broth as the soup base. Besides this, we’re adding diced tomatoes and tomato paste along with the lasagna strip pieces to give it the traditional lasagne taste we all love and crave.

But wait! While we won’t be adding cheese in the soup directly, we’ll add it on top right before serving. The warm instant pot lasagna soup will melt the cheese slowly into the soup, making it creamier the more it melts.

As a result, you get a steaming bowl of warm, cheesy, and creamy deliciousness; that’s just the thing you need to brighten up your day!

The instant pot lasagne soup is an ideal starter option for a 3-course dinner, something to sip on rainy days, or a savory afternoon snack option. Plus, there’s no right to have soup. You want soup; you make soup. Period!

Tips and Tricks

Here are some useful tips and tricks for a lip-smacking lasagna soup recipe:

1. You can use store-bought tomato paste or homemade for this recipe, based on what you find convenient.

2. Cheese is an important ingredient for this recipe to make the soup tasty and creamy, so I suggest not leaving it out. You can opt for low-fat or some other cheese if you think regular cheese is too heavy.

3. Add an extra cup of vegetable broth to the soup if you prefer a high liquid to noodle ratio.

4. If you store and reheat the soup, add extra broth as the lasagna strips tend to soak up all the liquid.

5. For added flavor, you can switch vegetable broth with chicken broth.
