Why this recipe works

There are two primary reasons why this crockpot lasagna soup recipe works – minimal prep time and a cooking time that allows you to get things done in between. Besides having to cook the lasagna noodles, the only other thing you need to do is cook the meat and dump everything else together.

This easy lasagna soup recipe also feeds a crowd. Make the best lasagna soup whether you have a large family or looking for something to take to a big potluck – this is it.

Recipe Ingredients

Meats: Lean ground beef and Italian sausage are cooked and browned together to add both flavor and heartiness to the lasagna soup.
Beef Stock: Helps create additional flavor and a soupy base.
Tomatoes: Three types of tomato-like ingredients are needed – crushed tomatoes, diced tomatoes, and tomato paste.
Seasonings: Garlic, Italian seasoning, salt and pepper, and crushed red pepper create an amazing taste.
Diced Onion: I used a yellow onion. You can use sweet onion for this recipe.
Fresh Herbs: Basil and parsley are used for the cheese mixture, while fresh spinach leaves are added to the soup just before serving.
Cheeses: Ricotta, mozzarella cheese, and parmesan cheese combine to make an irresistible cheese mixture that’s added to the bowl when serving the soup.

Variations

Vegetarian: Easily make this lasagna soup vegetarian-compatible by leaving out the meat and adding a few more vegetables of your choice. Think bell pepper, zucchini, squash, etc. You’ll also want to swap the beef broth for vegetable broth.
Mexican Style: Give your crockpot lasagna soup a Mexican flare by adding fajita seasoning, black beans, corn, and salsa. My Taco Soup recipe is a great base to start!
Switch Up the Meats: If you’re looking for slightly healthier meat versions, try using ground chicken (or ground turkey) and chicken broth.

How to Serve

This slow cooker lasagna soup can be served with a dollop of the ricotta topping and topped with additional sprigs of fresh basil. You can’t go wrong with adding a dollop of sour cream, too or just shredded mozzarella cheese! It also pairs exceptionally well with a slice of garlic bread or bite-size pieces of Italian bread.

As with any type of soup, you can’t go wrong with serving a soup and salad combination.

Recipe FAQs

Can I cook the lasagna noodles in the soup?

I do not recommend it because the noodles can become overcooked and turn into a gummy texture.

Am I able to use a different type of pasta?

Absolutely! If you want to switch things up a bit, consider using a different pasta noodle of your choice. Remember to cook them separately, then add them with the fresh spinach at the end.

Can I use frozen spinach? If so, how much?

Yes. I recommend starting with approximately a fourth of a cup (2-3 ounces) and adding more according to your personal preference.

What would happen if I add cheese to the soup?

Adding cheeses to this lasagna soup would begin to make it thick in texture and more like a casserole versus a soup, which is runny.

Do I drain the cans of tomatoes?

No. The liquid from the cans will help create more soup.

How do I store leftovers?

Wait for the soup to cool completely, and then put the remainder of it in an airtight container. Keep it in the refrigerator for up to 3 days. It also freezes well for up to 3 months.
