Crockpot Lasagna

Introduction

This Crockpot Lasagna is the ultimate solution for feeding a crowd with minimal effort. You get all the classic, comforting layers of a traditional lasagna—meaty sauce, creamy cheese filling, and gooey melted cheese—but your slow cooker does all the work.

Prep & Cook Time

• Prep Time: 10 minutes
• Cook Time: 180 minutes (3 hours)
• Total Time: 190 minutes (3 hours 10 minutes)
• Servings: 15

Ingredients

• ½ lb lasagna noodles (regular or oven-ready, uncooked)
• 1 lb Italian sausage (bulk, or links with casings removed)
• ½ lb ground beef
• 1 cup onion (chopped, about 1 large onion)
• 2 cloves garlic (minced)
• 28 oz can of tomatoes (cut up, undrained)
• 12 oz can of tomato paste
• 2 teaspoon sugar
• 2 teaspoon salt
• 1 ½ teaspoon dried basil leaves
• ⅕ teaspoon fennel seed
• ¼ teaspoon coarse black pepper
• 15 oz ricotta cheese
• 1 large egg (beaten)
• 1 tablespoon dried parsley flakes (or 2 teaspoon fresh minced parsley)
• ½ teaspoon salt
• ½ teaspoon coarse black pepper
• 4 cups shredded mozzarella cheese
• ¾ cup Parmesan cheese

Instructions

1. In a large skillet over medium heat, cook the Italian sausage, ground beef, onion, and garlic until the meat is browned and the onion is tender. Drain any excess fat.
2. To the meat mixture, stir in the undrained tomatoes, tomato paste, sugar, 2 teaspoons salt, dried basil, fennel seed, and ¼ teaspoon black pepper. Bring to a simmer, then remove from heat.
3. In a medium bowl, combine the ricotta cheese, beaten egg, dried parsley flakes, ½ teaspoon salt, and ½ teaspoon black pepper.
4. Spoon about 1 cup of the meat sauce into the bottom of a 6-quart or larger slow cooker.
5. Layer ingredients in this order over the sauce: 3-4 lasagna noodles (break them to fit as needed), ⅓ of the ricotta mixture, ¼ of the mozzarella cheese, and 1 ½ cups of meat sauce. Repeat the layers two more times.
6. For the final top layer, after the last of the sauce, sprinkle the remaining mozzarella cheese and all of the Parmesan cheese.
7. Cover and cook on LOW for 3 hours. The lasagna is done when the noodles are tender and the cheese is melted and bubbly. Let it rest, uncovered, for 15-20 minutes before serving to allow it to set.

Variations

• No-Precook Method: For an even faster prep, skip browning the meat. Simply crumble the raw sausage and beef directly into the slow cooker with the onion, garlic, and sauce ingredients, mix well, and proceed with layering.
• Crisp Top: For a more textured top, transfer the finished lasagna to a broiler-safe dish and broil for 2-3 minutes after cooking to lightly brown the cheese.
• Single-Service Layers: Create individual portions by using small, oven-safe dishes inside the slow cooker (if they fit) or by layering the ingredients in disposable foil tins placed on the rack of your cooker.
• Herb-Forward: Boost the herb flavor by stirring 1 teaspoon of dried oregano into the meat sauce and adding ½ teaspoon of dried thyme to the ricotta mixture.

Tips for Success

• Let it rest! Allowing the lasagna to sit for 15-20 minutes after cooking is crucial for clean slices and the perfect layered texture.
• For easier serving, use a slow cooker with an oval shape, as it accommodates the long noodles better than a round one.
• If using regular (not oven-ready) noodles, ensure every noodle is surrounded and covered by sauce to prevent dry, crunchy spots.

Storage & Reheating

Store cooled leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave, or warm larger portions, covered with foil, in a 350°F oven until heated through.

FAQ

Can I use only ground beef or only sausage?

Yes, you can use 1.5 lbs of all ground beef or all Italian sausage. The flavor profile will change slightly.

Do I really not have to boil the noodles?

My slow cooker is smaller than 6 quarts. Can I still make this?

You can halve the recipe for a smaller slow cooker. The cook time will be slightly less, so start checking for doneness around the 2-hour mark.

Why is there sugar in the sauce?

The sugar helps balance the acidity of the tomatoes, creating a more rounded, rich flavor.

Can I cook this on HIGH?

It’s not recommended, as the shorter, hotter cook time can lead to overcooked edges and undercooked noodles in the center. LOW and slow is best for even cooking.

Can I prepare this ahead of time?

You can assemble the layers in the slow cooker insert, cover, and refrigerate it up to 24 hours in advance. Let it sit at room temperature for 30 minutes before cooking as directed, adding 15-30 minutes to the cook time.
