Instant Pot Lasagna Soup is a quick and easy soup recipe filled with hearty sausage, rich tomato broth, and tender pasta. It is one of the best one-pot meals around and is ready in just 30 minutes thanks to the Instant Pot.
All of the flavors that you love in classic lasagna come are featured in this simple recipe for Instant Pot Lasagna Soup. Pair with a tossed Greek salad and homemade garlic toast for a delicious meal the entire family will rave about.
I will never forget the first time my mom made Lasagna Soup for me. I was a bit skeptical, as her lasagna was one of my all-time favorite meals. But after one bite, I fell head over heels in love with this Italian Soup.
I have been making my mom's lasagna soup for decades now on the stovetop. And while the traditional lasagna soup is a relatively quick meal, Instant Pot Lasagna Soup is RIDICULOUSLY fast to make.
Filled with Italian Sausage, carrots, onions, and pasta in a rich tomato-based sauce, this hearty Italian soup is comforting and soothing to my soul. It has all the flavors of traditional lasagna, in soup form.
It is so incredibly flavorful, so hearty, and downright delicious. Not to mention incredibly easy to make.
Ingredients Needed
- Sausage: Use any Italian flavored sausage you like--chicken, turkey, or pork.
- Tomato Sauce: I recommend using pre-made spaghetti sauce or marinara gives this soup so much more flavor than using plain canned tomato sauce.
- Noodles: Use 1 cup of any variety of noodles you like. Broken up lasagna noodles, elbow noodles, bow-tie noodles, etc.
- Spinach: Feel free to use kale in place of spinach. You can also use defrosted and drained frozen spinach but add to the soup BEFORE pressure cooking for the best results.
Step-By-Step Directions
- Turn Instant Pot to Saute function and add in a bit of oil.
- Once heated, add in the sausage, onions, and carrots and saute until the sausage is no longer pink.
- Add in the garlic and saute for 1 minute longer and then TURN the Instant Pot off.
- Drain off excess grease if needed and return the inner pot back to the Instant Pot.
- Add in the chicken stock and scrape up any browned bits on the bottom of the inner pot to prevent a burn warning.
- Add stewed tomatoes, spaghetti sauce, seasonings, and pasta to the pressure cooker and stir to combine.
- Place lid on Instant Pot and turn the knob to the sealed position and cook on High Pressure for 4 minutes.
- Once cook time has elapsed, allow pressure to release naturally for 5 minutes. This is the perfect amount of time to cook the noodles perfectly.
- After 5 minutes have elapsed, do a quick release for any remaining pressure. Normally, I state to do a natural pressure release when cooking soups, as the inner pot is filled with hot liquid. But in order to not overcook the noodles, you only want to release pressure for 5 minutes. Just be sure to stand away from the vent knob when you do a quick release of pressure to protect yourself from hot steam or liquid that may escape from the vent knob. You may even opt to place a kitchen towel lightly over the knob to prevent splatter.
- Stir spinach into hot Lasagna soup, allowing the spinach to wilt.
- Serve Lasagna Soup with shredded or fresh Mozzarella Cheese and shredded Parmesan Cheese.
Modifications and Tips
- 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.
- Low-Fat Version: To cut back on the fat in this soup, opt to use lean chicken Italian sausage and/or be sure to drain off any excess grease after sauteeing. Alternatively, don't drain off the excess grease rendered from the sausage for a really rich and decadent soup.
- 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.

It was wonderful. My son and wife thought it was great. I used too large of a pasta, penne, for a soup, but all was forgiven because of the taste. Will definitely be making again. Thanks Kristen

So glad you all enjoyed it so much Robin!

I've made this recipe 5 or 6 times, so I think it's high time I review it.
It was surprisingly difficult for me to find a lasagne soup recipe that didn't include premade marinara sauce, and this one is so much better for it. I always tweak a few things when making it myself: I use dried pesto tortellini (from Trader Joe's), double it, add a cup more water, and increase the cooking time. Last time I added some balsamic vinegar, and that took everything up a notch. I've made it at least once a week for the past month, and I feel a little silly making the same thing over and over again, but it is just THAT GOOD.

Jeffrey Hall
Fantastic! Incredible flavor, and so fast and easy to make. I browned the sausage and onions/carrots/garlic in a skillet to I could drain off the excess fat/oil. I used campanelle pasta and one each of linguesa and hot Italian sausage. Incredible. I also opted for the red pepper flakes, good call!

I wanted to give this recipe a fair review because I accidentally burnt the first batch. This turned out great! It was hearty and easy to make. It had great flavor, and can't wait to eat the leftovers tomorrow! I served it with garlic bread sticks to dip in the soup. Thanks for the recipe, and updating it 😉. I shared this on Facebook for all my IP friends.

Hi Megan I am so glad you enjoyed this recipe so much! We love it ourselves. And thank you for pointing out that 1 -16 ounce can tomatoes can read like 116 ounces. I want to make my recipes super clear and helpful, but knowing how you interpret recipes helps me improve. Enjoy those leftovers 🙂
