How to Make Instant Pot Lasagna Soup

This soup comes together by browning the meat, building the sauce, pressure cooking the noodles, and finishing each bowl with Parmesan.

Brown the Meat

Turn on a multi-functional pressure cooker, such as an Instant Pot, and select the Sauté function.

Add the Italian sausage and ground sirloin to the pot.

Cook until browned, about 5 minutes.

Drain and discard the grease, then set the meat aside.

Cook the Onion

Add the olive oil to the Instant Pot.

Swirl it around so the bottom of the pot is evenly coated.

Add the finely chopped onion and cook until just soft but not browned, about 5 minutes.

Add the Garlic

Stir in the minced garlic.

Cook until just fragrant, about 1 minute.

Deglaze the Pot

Pour in the chicken broth.

Scrape up the browned bits from the bottom of the pot.

This adds flavor and helps prevent anything from sticking during pressure cooking.

Add the Sauce and Meat

Pour in the marinara sauce.

Add the cooked meat mixture back to the pot.

Season with salt and freshly ground black pepper.

Stir to combine.

Add the Lasagna Noodles

Add the broken lasagna noodles.

Make sure the noodles are completely submerged in the sauce and broth.

Pressure Cook the Soup

Close and lock the lid.

Select high pressure according to the manufacturer’s instructions.

Set the timer for 3 minutes.

Allow 10 to 15 minutes for the pressure to build.

Release the Pressure

Carefully release the pressure using the quick-release method according to the manufacturer’s instructions, about 5 minutes.

Unlock and remove the lid.

Taste and Adjust

Taste the soup and adjust the salt if needed.

Stir gently so the noodles and meat are evenly distributed.

Serve With Parmesan

Ladle the soup into bowls.

Top each serving with 1 teaspoon of grated Parmesan cheese.

Serve fresh and enjoy.

Why This Instant Pot Lasagna Soup Works

This recipe works because it builds classic lasagna flavor in a faster, easier way.

The sausage and ground sirloin create a savory meat base. The onion and garlic add depth. The marinara sauce gives the soup rich tomato flavor, while the broken noodles make it feel hearty and familiar.

The pressure cooker helps the noodles cook quickly right in the broth and sauce, so every bite is full of flavor.

Why Use Broken Lasagna Noodles?

Broken lasagna noodles are perfect for this soup because they give you the feel of lasagna without needing to layer anything.

They also make the soup easier to eat with a spoon.

This recipe is a great way to use up noodles that may be broken in the box.

Why Deglaze the Instant Pot?

Deglazing is important because it lifts the browned bits from the bottom of the pot.

Those bits add flavor to the soup, and scraping them up helps prevent sticking or burning during pressure cooking.

Chicken broth works perfectly for this step.

Should You Serve This Soup Fresh?

Yes, this soup is best served fresh.

The noodles will continue to absorb the liquid as the soup sits, which can make the leftovers thicker.

It will still taste good later, but the texture is best right after cooking.

Can You Make Instant Pot Lasagna Soup Ahead of Time?

You can make it ahead, but it is best fresh because the noodles absorb the broth as they sit.

For a better make-ahead option, prepare the meat and sauce base ahead of time, then add the noodles and pressure cook when you are ready to serve.

This keeps the noodles from getting too soft.

How to Store Instant Pot Lasagna Soup

Store leftover soup in an airtight container in the refrigerator.

It will keep for 2 to 3 days.

The soup will thicken as the noodles absorb liquid, so add a splash of broth or water when reheating.

Can You Freeze Instant Pot Lasagna Soup?

Freezing the finished soup is not ideal because the noodles may become soft after thawing.

For best results, freeze the meat and marinara broth base without the noodles.

When ready to serve, thaw the base, heat it, and add freshly cooked noodles.

How to Reheat Instant Pot Lasagna Soup

Reheat gently on the stovetop over medium-low heat.

Add extra broth or water to loosen the soup if it has thickened.

You can also reheat individual portions in the microwave, stirring between intervals.

Top with fresh Parmesan after reheating.

What to Serve With Instant Pot Lasagna Soup

Instant Pot Lasagna Soup is hearty on its own, but simple sides make it even better.

Serve it with garlic bread, breadsticks, a green salad, Caesar salad, roasted vegetables, steamed broccoli, or crusty Italian bread.

For toppings, try extra Parmesan, ricotta, mozzarella, fresh basil, parsley, red pepper flakes, or a drizzle of olive oil.

Instant Pot Lasagna Soup Substitutions and Variations

One of the best things about this soup is how easy it is to adjust.

Add Ricotta

Add a spoonful of ricotta to each bowl for a creamy lasagna-style topping.

Add Mozzarella

Sprinkle shredded mozzarella over the hot soup for extra cheesy flavor.

Use Ground Beef

Ground beef can replace ground sirloin if that is what you have.

Use Hot Italian Sausage

Hot Italian sausage adds more spice and bold flavor.

Add Herbs

Try dried basil, oregano, Italian seasoning, or ground fennel seeds.

Add Vegetables

Spinach, zucchini, mushrooms, or bell peppers can make the soup even heartier.

Use Beef Broth

Beef broth can replace chicken broth for a deeper flavor.

Make It Spicier

Add crushed red pepper flakes or use spicy marinara sauce.
