This Instant Pot Lasagna Soup Recipe delivers the flavors of classic lasagna without the work!
Made with hearty Italian sausage, Italian stewed tomatoes, and rich marinara, Instant Pot Lasagna Soup tastes like it has been simmered for hours yet is on the table in under 30 minutes, making it an easy family dinner perfect for a busy weeknight.
Kristen's Key Tips for Instant Pot Lasagna Soup
- Use Italian Sausage over Ground Beef. Using Italian sausage helps to build an incredibly flavorful soup.
- Swap Out Tomato Sauce for Marinara. Because marinara sauce is already seasoned, it gives lasagna soup an incredible depth of flavor with minimal effort or added ingredients.
- An Exception to the Rule. I typically stress using natural pressure release when pressure cooking soups. However, for this recipe you will need to release the pressure after 5 minutes the noodles don't overcook.
How to Make Instant Pot Lasagna Soup
If you are unfamiliar with cooking in an Instant Pot or the functions of your Instant Pot, be sure to start with my guide for using an Instant Pot for the best results on this and future recipes. You will find the full recipe in detail in the recipe card below.
- Sauté Sausage with Aromatics. Using the sauté function, sauté the ground sausage until the sausage is nearly fully browned, breaking it up into small bits as it cooks.
- Add Aromatics Garlic. Add minced onion, diced carrots, and minced garlic, and sauté briefly to soften the onions and toast the garlic. Hit cancel to turn off the sauté function.
- Deglaze Inner Pot. Add in a bit of the chicken stock and scrape up any browned bits on the bottom of the inner pot to prevent a burn warning.
- Layer Ingredients. Add the remaining broth, stewed tomatoes, spaghetti sauce, seasonings, and pasta to the pressure cooker and stir gently to just combine.
- Pressure Cook. Secure the lid on Instant Pot and turn the knob to the sealed position. Set to cook High Pressure for 4 minutes.
- Let Pressure Release for EXACTLY 5 Minutes. Once the cooking cycle is complete, wait exactly 5 to do a quick release pressure. Do this by carefully knocking the pressure release knob from the sealed to venting position. Be sure to stand back to protect yourself from hot steam or liquid that may escape from the vent knob.
- Add Spinach. If using, stir fresh spinach into the soup and let sit for a minute or two to wilt before serving.
- Serve. Instant Pot Lasagna Soup is begging to be topped with mozzarella and parmesan cheese, or even a dollop of ricotta cheese. Finish you meal by pairing this soup with a Caesar salad or Olive Garden salad and and homemade garlic toast or Olive Garden breadsticks for a delicious meal the entire family will rave about.
Recipe Modifications
- Gluten-Free Version: I have had success using Barilla gluten-free noodles. Other brands have not been successful, as they give off too much starch and don't hold up well when pressure-cooked.
- No lasagna noodles? Use elbow noodles or bow-tie noodles, as they require the same cooking time.
- Hate the texture of diced tomatoes? Blend or puree the stewed tomatoes before adding to your inner pot. I do this for my picky eaters all the time!
- No Instant Pot? Enjoy my recipe for stove-top lasagna soup.
Storing Leftovers
- Refrigerate: Allow the Instant Pot lasagna soup to cool then transfer it to an airtight container and store in the refrigerator for up to 3 days.
- Freeze: Allow the Instant Pot lasagna soup to cool then transfer it to a freezer-safe container leaving 1 inch of space for expansion. Freeze for up to 3 months.
- Reheat: If needed, allow the soup to defrost overnight in the refrigerator. Reheat individual servings in heat-safe bowls in 60-second intervals until warmed through. You may need to add in a bit of extra stock to reheat, as the noodles will absorb the liquid as they sit.

Ingredients
- ½ tablespoon extra virgin olive oil
- 1 pound Homemade Italian Sausage, or your favorite store-bought ground Italian sausage
- 1 small yellow onion, minced
- 1 large carrot, peeled, and diced
- 2 cloves garlic, minced
- 4 cups low sodium chicken stock, or vegetable broth
- 1 teaspoon dried oregano
- ½ teaspoon kosher salt
- ½ teaspoon pepper
- ¼ teaspoon red pepper flakes, optional
- 1 cup dried pasta, such as rotini, elbow noodles, or broken-up sheets of lasagna noodles
- 1 (15-ounce) can Italian Stewed Tomatoes
- 1 cup spaghetti sauce, or marinara sauce
- 2 cups fresh spinach
- mozzarella and parmesan cheese, for serving
Instructions
- Turn the Instant Pot to sauté, add ½ tablespoon extra virgin olive oil to the inner pot, and let heat briefly, 30-60 seconds. Once the oil is heated add in 1 pound Homemade Italian Sausage with 1 small yellow onion (minced) and 1 large carrot (diced) and cook until almost no longer pink, breaking up the sausage as it cooks.
- Add 2 cloves garlic (minced) and sauté for 2-3 minutes longer, to soften the onions. Hit cancel to turn off the Instant Pot off. If needed, remove the inner pot, drain off excess grease, and then return the inner pot back to the instant pot.
- Add about 1 cup of the 4 cups low sodium chicken stock to the inner pot and use a spatula or spoon to scrape up any browned bits on the bottom of the inner pot. Add the remaining stock. *Adding a small amount makes it so you don't splash yourself when deglazing the inner pot.
- Season the broth with 1 teaspoon dried oregano, ½ teaspoon kosher salt, ½ teaspoon pepper, and ¼ teaspoon red pepper flakes. Stir in 1 cup dried pasta and then top with 1 (15-ounce) can Italian Stewed Tomatoes and 1 cup spaghetti sauce (DO NOT STIR!)
- Place the lid on the Instant Pot and be sure the vent knob is sealed or locked. Set to cook on high pressure for 4 minutes by hitting the manual or pressure cook button and use the +/- buttons to adjust to read 4.
- Once the cook time has elapsed, allow the pressure to release naturally for exactly 5 minutes. Then do a quick release for any remaining pressure by SLOWLY knocking the vent knob from sealed to venting. Be sure to stand away from the vent knob, to protect yourself from steam and liquid that may escape.
- Open the Instant Pot, stir in 2 cups fresh spinach, pop the lid back on the Instant Pot and let set for 2-3 minutes, just to let the spinach wilt.
- Serve the lasagna soup with mozzarella and parmesan cheese as desired. Alternatively, dollop the soup with ricotta cheese before serving.
Notes
Sausage: Use any Italian sausage you like--chicken, turkey, or pork.
Noodles: Use 1 cup of any variety of noodles you like. Broken-up lasagna noodles, elbow noodles, bow-tie, etc.
Gluten-Free Modifications: Be sure the sausage and chicken broth you use are both gluten-free and use Barilla gluten-free noodles. Other brands give off too much starch and do not hold up well in this Instant Pot recipe.
Spinach: Feel free to use frozen defrosted and drained spinach in place of fresh spinach, just add it to Lasagna Soup BEFORE cooking on high pressure.
Storage: Leftover Lasagna soup may be stored in an airtight container in the refrigerator for up to 3 days or frozen for up to 3 months. You may need to add in a bit of extra stock to reheat, as the noodles will absorb the liquid as they sit.

Thrilled to hear this is going on repeat! Thanks for taking the time to leave a comment and review as well. It is appreciated!
Made this last night and it is hands down my new favorite soup ever! So super easy and the flavor is beyond good.
Thank you so much for sharing, Ribin! I love hearing this is a favorite now.
This turned out excellent! I made my own Italian sausage from ground pork. I cooked exactly like recipe said and the pasta turned out perfect. Thank you!
Thank you for sharing Joyce! I am so happy to hear you enjoyed this soup!
I don't pretend to be a great chef, nor even a good cook. I prepared the lasagne soup (with my wife acting as sous chef and advisor). It was absolutely fabulous! That had little to do with my abilities, but because of the easy-to-follow and well-thought-out recipe. Thank you! This had become our go-to website for recipes. Maybe you could do a bit more Asian-based recipes? Again, thanks!
Hi Kevin! I am so happy you found this recipe to be so enjoyable and easy to follow. And I hear you on more Asian-based recipes. Thank you for the suggestion!
