Ingredient Checklist

• 1 pound lean ground beef
• 1 medium yellow onion, diced
• 3 cloves garlic, minced
• 1 (28-ounce) can crushed tomatoes
• 1 (15-ounce) can tomato sauce
• 4 cups low-sodium beef broth
• 1 tablespoon tomato paste
• 2 teaspoons Italian seasoning
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 8 uncooked lasagna noodles, broken into 2-inch pieces
• 1 cup ricotta cheese
• 1 1/2 cups shredded mozzarella cheese
• 1/3 cup grated Parmesan cheese
• 2 tablespoons chopped parsley (for garnish)

Slow-Cooker Directions

1. Heat a skillet over medium and brown the ground beef with diced onion, breaking the meat into small crumbles, about 7–8 minutes.
2. Drain excess fat from the browned beef.
3. Add minced garlic to the skillet and cook until fragrant, about 30 seconds.
4. Transfer the beef, onion, and garlic mixture to the slow cooker.
5. Pour in crushed tomatoes, tomato sauce, beef broth, tomato paste, Italian seasoning, salt, and black pepper; stir to combine.
6. Cover and cook on LOW for 4½ to 5 hours.
7. Break lasagna noodles into ~2-inch pieces.
8. After slow cooking, stir in the broken lasagna noodles.

9. Set the slow cooker to HIGH, cover, and cook 25–35 minutes, stirring once during cooking, until the noodles are tender but not mushy.

   

10. While the noodles finish, mix ricotta and grated Parmesan until smooth.
11. Ladle soup into bowls and top each serving with shredded mozzarella, a dollop of the ricotta mixture, and chopped parsley.

Pro Tips for Best Results

• Make sure to brown and drain the ground beef well (see the browning step in our Beef Chili Recipe for the color and texture to aim for). This step cuts down on any greasy broth and keeps your soup clean and tasty.
• Add the lasagna noodles toward the end of cooking. This stops them from getting too soft and turning into mush in the slow cooker.
• If you like your noodles on the firmer side, check them a little early and pull them once they’re perfectly al dente.
• Using low-sodium broth is a great idea—taste before salting more because some canned tomato products can be salty already.
• When the noodles are cooking, stir gently but regularly to make sure they cook evenly and don’t stick together.
• If your soup ends up too thick after adding the cheeses, just pour in a splash more broth to loosen it up.

Easy Swaps and Add-Ins

• Replace the ground beef with ground turkey or spicy Italian sausage for a new flavor kick.
• For a vegetarian slow cooker lasagna soup, leave out the meat and swap beef broth for vegetable broth. Add cooked lentils or chopped mushrooms for a meaty texture, or explore a tomato-and-zucchini base in our Tomato Zucchini Soup Recipe.
• Use gluten-free lasagna noodles if you need to go gluten-free, or swap the noodles for short pasta like penne or rotini, broken into bite-size pieces.
• Mix in a few handfuls of fresh spinach or kale at the end of cooking. Just stir it in and let it wilt for a boost of green goodness.
• If you like a different topping texture, try using cottage cheese instead of ricotta for a twist.

Storage and Make-Ahead Tips

• Store any leftovers in an airtight container in the fridge for up to 3 to 4 days. Make sure it’s completely cooled first.
• You can freeze this soup for up to 2 months, but pasta does tend to get mushy after freezing. For best texture, freeze the soup base without noodles and add fresh or slightly undercooked noodles when reheating; for a low-carb swap, try adding cabbage noodles.
• To reheat, thaw overnight in the fridge if frozen, then warm gently on the stovetop over medium-low heat. Add a splash of broth as needed to keep it saucy. Or microwave single portions, adding cheeses and fresh toppings right before serving.
• This recipe also works great as a make-ahead meal—you can prep the meat and tomato base ahead, refrigerate it, then add the noodles and finish cooking when ready to eat. That same base also doubles as a speedy start for keto cabbage roll casserole later in the week.

Quick Answers to Common Questions

• Can I use no-boil lasagna noodles?

  Absolutely! Just break them into pieces like usual and add them in the same way. Keep an eye on them since some brands soften faster and may need less cooking time.

• Can I cook this on the stovetop instead of the slow cooker?

  Yes, you can! Simmer the browned beef and sauce in a large pot for 20 to 30 minutes. Then stir in the broken noodles and cook on low until tender, adjusting the liquid to keep the soup just right; for extra stovetop simmering pointers on browning and managing liquid, see How to Make Homemade Chili.

• Is it okay to freeze leftovers with the noodles included?

  You can, but expect the noodles to get softer after freezing and reheating. For the best texture, freeze just the soup base without noodles, then add fresh or slightly undercooked noodles when you reheat.

• Is there a gluten-free option?

  Yes! Just swap in gluten-free lasagna noodles or a small gluten-free pasta. Remember, cooking times may differ a bit.

• How can I reduce the sodium?

  Use low-sodium broth and no-salt-added canned tomato products, then hold back on the salt during cooking. Taste toward the end and add more salt only if you need it.
