Crockpot Lasagna Soup – Easy Set-and-Forget Comfort

It's 6:40 on a Tuesday, the kids are circling the kitchen, and you have exactly zero interest in layering noodles. This soup is your answer. You dump the base in the slow cooker before the day gets loud, then stir in broken lasagna noodles and a cheesy ricotta swirl right at the end.

The trade-off is real: you can't rush a slow cooker. But the payoff is a pot of tomato-beef broth that tastes like it simmered all afternoon, with tender noodle pieces and a dollop of herbed ricotta that melts into every spoonful.

If you've ever had lasagna soup come out gluey or watery, this method fixes both. The noodles go in late, and the ricotta goes in last, so nothing turns to mush.

About the Ingredients

1 lb (450g) ground beef, 85% lean

85/15 keeps the broth flavorful without a grease slick. Ground turkey or Italian sausage work well here; if using sausage, skip the extra fennel in your seasoning.

1 medium yellow onion, diced (about 1 cup / 160g)

Yellow onion melts into the broth; white onion is sharper and holds its shape longer. Frozen diced onion is a fine shortcut, no thawing needed.

3 cloves garlic, minced

Fresh garlic gives the best bite, but 1 teaspoon garlic powder works in a pinch. Add powder with the dried herbs so it doesn't scorch.

1 jar (24 oz / 680g) marinara or plain tomato sauce

Marinara brings built-in seasoning; plain sauce lets you control the salt. If you only have crushed tomatoes, add 1 teaspoon sugar to balance the acid.

4 cups (960ml) low-sodium beef broth

Low-sodium matters because the sauce and cheese add plenty of salt. Chicken broth or vegetable broth both substitute cleanly.

1 can (14.5 oz / 410g) diced tomatoes, undrained

Fire-roasted diced tomatoes add a smoky edge that tastes slow-cooked. Don't drain them, the juice is part of your broth.

1 teaspoon dried oregano, plus 1 teaspoon dried basil

Dried herbs hold up through hours of heat better than fresh. If you use fresh basil, stir it in at the very end instead.

8 oz (225g) lasagna noodles, broken into 1- to 2-inch pieces

Regular lasagna noodles, not no-boil, give the best texture here. No-boil noodles work but go soft faster, so check them at 20 minutes.

1 cup (245g) whole-milk ricotta

Whole-milk ricotta stays creamy when stirred into hot soup. Cottage cheese blended smooth is a lighter swap that tastes nearly identical here.

1 cup (100g) shredded mozzarella, plus more for serving

Freshly shredded melts smoother than pre-shredded, which is coated in starch. Part-skim mozzarella is fine and less rich.

1/4 cup (25g) grated Parmesan

Parmigiano-Reggiano has the deepest flavor; Grana Padano is a cheaper stand-in with a similar salty punch. Skip the green can here.

2 tablespoons chopped fresh parsley or basil, for serving

Flat-leaf parsley is milder; basil is more classic. Either way, add it off the heat so it stays green.

Tips & Tricks

• Cook noodles separately if you plan on leftovers. Noodles sitting in broth overnight soak up liquid and turn to paste. Boil them al dente and add to individual bowls instead.
• Brown the beef properly before it goes in. Raw ground beef dumped into the crock releases gray liquid and dull flavor. Get it golden brown in a hot skillet first, about 6 to 8 minutes over medium-high heat (about 200°C on an electric skillet), then scrape every browned bit into the pot.
• Taste before you salt. Marinara, broth, and Parmesan all carry salt, and a slow cooker concentrates flavor as liquid evaporates. Season at the end, not the start.
• Keep the ricotta cold until serving. Stirring it into the whole pot makes the broth cloudy and dilutes the cheese. Dollop it into bowls instead.

Step-by-Step Instructions

1. Brown the beef

Heat a large skillet over medium-high heat, about 400°F (204°C), and cook the ground beef with the onion for 6 to 8 minutes until the beef is browned and the onion is soft and translucent. You're looking for no pink left and browned bits on the pan bottom.

2. Load the slow cooker

Scrape the beef mixture into a 6-quart slow cooker. Add the garlic, marinara, beef broth, diced tomatoes with their juice, oregano, and basil. Stir once to combine.

3. Cook on low

Cover and cook on LOW for 5 to 6 hours or on HIGH for 3 hours. The broth should be bubbling gently at the edges and smell deeply tomatoey when you lift the lid.

4. Add the noodles

Stir in the broken lasagna noodles, cover, and cook on HIGH for 25 to 30 minutes, until the noodles are tender but still have a slight bite. Check at 20 minutes if your slow cooker runs hot.

5. Mix the cheese topping

While the noodles cook, stir together the ricotta, mozzarella, Parmesan, and a pinch of black pepper in a small bowl. Keep it in the fridge until serving.

6. Season and serve

Taste the soup and add salt and pepper as needed. Ladle into bowls and top each with a generous spoonful of the ricotta mixture and fresh parsley. The cheese will melt into ribbons as you eat.

Delicious Variations

Spicy Sausage Version

Swap the ground beef for hot Italian sausage and add 1/2 teaspoon red pepper flakes with the herbs for a broth with real heat.

Vegetarian Mushroom Lasagna Soup

Replace the beef with 12 oz (340g) cremini mushrooms browned in olive oil, and use vegetable broth. The mushrooms give the same meaty depth.

Creamy White Lasagna Soup

Skip the marinara, use chicken broth, and stir 1/2 cup heavy cream in with the cheese topping for a rich, pale, Alfredo-style bowl.

👨‍🍳 Chef's Note: A 6-quart slow cooker is the sweet spot here; anything smaller and the noodles crowd and cook unevenly. If yours runs hot, check the noodles at 20 minutes.
