Instant Pot Seafood Lasagna Soup

by Kristen

All those Instant Pot Lasagna Soup recipes on the interwebs had me drooling!  I decided to switch up the ingredients by turning my favorite kind of lasagna into a soup!   This creamy white seafood lasagna soup might be my new favorite way to enjoy lasagna pasta!  Cooking seafood lasagna soup in your pressure cooker takes literally minutes!  I used shrimp in this recipe but you can also use crab, imitation crabmeat, or scallops in this recipe.  You will love this super-rich soup with Italian seasoning and creamy broth! 

One of my favorite Instant Pot recipes I have seen floating around the interwebs is Lasagna Soup!  I love the idea because it looks delicious, takes only a few minutes to make.  This tastes like seafood lasagna without all the work!

In my house, we don’t eat meat this time of year, and I started brainstorming some seafood recipes to make for my family.   My attitude towards Lenton recipes is that if you’re spending lots of money on seafood, you’re missing the point of the season.  However, I had a couple of packages of frozen shrimp in my freezer that I needed to use up, so I decided to put together this seafood lasagna soup for our Ash Wednesday dinner.

I love being able to make lasagna without needing to create all those layers!  I highly suggest that you sprinkle some parmesan cheese, freshly ground black pepper, or fresh parsley on top of this soup while you eat it!

How do you make Seafood Lasagna Soup?

  • Start by cooking onions, garlic, and  1 lb of shrimp, or whatever seafood mixture you’re using the saute function.
  • Add a few veggies and some Italian spices
  • Stir in a jar of alfredo sauce and some vegetable broth or chicken broth.
  • Add broken lasagna noodles to your pot
  • You can add a few bay leaves or Italian seasoning if you like, but they’re not necessary.
  • Cook the soup in your Instant Pot for 6 minutes.  You read that right.  6 minutes. 
  • Top your soup with a delicious ricotta cheese mixture and Eat!

We don’t need to track calories, sodium, or carbohydrates when we’re making this soup 🙂 

The total time it takes to make this soup is about 25 minutes.  You need to make sure you account for prep time, the time it takes for your Instant Pot to come to pressure, and the time it takes to release naturally.  I never release the pressure right away when I make soup.  Your soup will splatter all over the place if you release pressure before it’s time.

What do I need for Seafood Lasagna Soup?

You will need:

  • 24 oz of baby shrimp
  • One onion
  • garlic
  • One carrot
  • 1 Zucchini
  • 1 cup broccoli
  • 1 15 ounces of alfredo sauce
  • 32 ounces vegetable broth
  • 1 cup of water

  • Optional: You can add a teaspoon of pepper flakes if you want to add some spice.
  • And Instant Pot You can use a large pot on the stove if you don’t have an Instant Pot. 

In My opinion, the best part about this soup is the ricotta cheese topping.  This is super easy to whip up and is the secret to making this soup taste like lasagna.  You will want to add the ricotta cheese topping right before serving the soup. You will love the taste of this white sauce

  5. Seal lid on instant pot. Cook on high pressure for 6 minutes. Let naturally release for 10 minutes.

  6. While the Instant Pot is cooking, prepare your ricotta cheese topping. Mix all of the cheeses in a bowl, and set aside.

  7. Serve up a bowl of seafood lasagna soup by adding soup to a bowl, and adding the ricotta mixture on top.

I made this soup using store-bought alfredo sauce if you want to make your own, I encourage you to do so!  I highly encourage this seafood lasagna soup!  It is so much better than lasagna out of the frozen aisle of the grocery store but doesn’t take all the time of homemade lasagna.

How many lasagna noodles do you use in this soup? And do think salmon would taste good if I already had cooked salmon and added it in after soup is cooked? I’m allergic to shellfish.

about 7-8 broken noodles. I do think salmon would taste great! It would be like a Scandinavian salmon chowder. I might add some dill
