How to Make The Best Crockpot Lasagna Soup
- Brown the Meats: In a large skillet or Dutch oven, cook the ground beef and Italian sausage over medium-high heat until browned and cooked through. Use a spoon to break up the meat as it cooks. Season with salt and pepper. Drain off any excess grease and transfer the meat to your slow cooker.

- Sauté the Aromatics: In the same skillet, heat the olive oil over medium heat. Add the chopped onion and sauté for about 5 minutes, until softened and translucent. Add the minced garlic and cook for one more minute until fragrant.

- Optional Step: Deglaze for Depth: For an authentic, deep Italian flavor, pour 1/2 cup dry red wine (such as Cabernet or Merlot) into the skillet, scraping up any browned bits on the bottom. Let it simmer until reduced by half before scraping the mixture into the slow cooker.
- Combine in Slow Cooker: Stir the tomato paste into the onion and garlic mixture and cook for 1 minute. Scrape the entire mixture into the slow cooker with the meat. Add the marinara sauce, red pepper flakes, parsley, oregano, basil, and chicken broth. Stir everything together until well combined.

- Slow Cook: Cover the crockpot and cook on low for 6-8 hours or on high for 3-4 hours.
- Prepare Cheese Topping: While the soup cooks, combine the ricotta cheese, mozzarella cheese, and Parmesan cheese in a small bowl. Mix well and refrigerate until ready to serve.
- Finish the Soup: About 30 minutes before serving, stir the broken lasagna noodles and heavy cream into the slow cooker. Turn the heat to high, cover, and cook until the noodles are tender (al dente). If using, stir in the fresh spinach during the last 5 minutes of cooking, allowing it to wilt.

- Serve: Ladle the hot soup into bowls. Top each serving with a generous dollop of the three-cheese mixture and garnish with fresh basil.

The 1 Secret to Perfect Lasagna Soup Leftovers (No Mush!)
The biggest complaint about leftover lasagna soup is that the noodles absorb all the broth and turn to mush. Here’s how to prevent that forever.
CRITICAL TIP: Cook The Noodles Separately!
For the best results, especially if you anticipate leftovers, do NOT add the noodles directly to the slow cooker. Instead, cook the lasagna noodles on the stovetop according to package directions until al dente. Store the cooked noodles and the soup base in separate airtight containers in the refrigerator. To serve, simply add the desired amount of noodles to a bowl, ladle the hot soup over them, and top with the cheese mixture. This guarantees perfectly textured noodles every time.
Variations and Substitutions
- Vegetarian: Omit the ground meat and sausage. Sauté diced mushrooms, zucchini, and bell peppers with the onion for a hearty vegetable base.
- Low-Carb: Swap the lasagna noodles for zucchini ribbons or palmini noodles. Add them during the last 5-10 minutes of cooking so they don’t get too soft.
- Protein Swaps: Feel free to use ground turkey or ground chicken instead of beef and sausage.
- Spice It Up: If you like more heat, increase the amount of red pepper flakes or add a dash of your favorite hot sauce. For more cozy soup ideas, check out our Crockpot White Chicken Chili or this delicious Santa Fe Soup.
Expert Tips for the Best Lasagna Soup
- Use Quality Marinara: Since the sauce is a key flavor component, using a high-quality jarred marinara sauce (like Rao’s) will make a noticeable difference.
- Parmesan Rind Boost: If you have a Parmesan cheese rind, toss it into the slow cooker at the beginning of the cook time. It will infuse the broth with a savory, umami depth. Just remember to remove it before serving.
- Don’t Skip the Browning: Taking the time to brown the meat and sauté the aromatics is essential for developing the rich, layered flavor that makes this soup taste like it simmered for days. If you love this method, you’ll also enjoy our Crockpot Chicken Parmesan Soup.
