Recipe Overview

Prep Time: 20 minutes
Cook Time: 4-6 hours
Total Time: 4 hours 20 minutes to 6 hours 20 minutes
Servings: 8
Yield: 1 lasagna
Dietary Type: Not specified

Ingredients

1 lb bulk Italian sausage
1 medium onion, 1/2 cup chopped
3 (15 ounce) cans Italian-style tomato sauce
2 teaspoons dried basil leaves
1/2 teaspoon salt
2 cups mozzarella cheese, shredded (divided)
1 (15 ounce) container part-skim ricotta cheese
1 cup parmesan cheese, grated
15 lasagna noodles, regular, uncooked

Equipment Needed

10-inch skillet
6-quart slow cooker
Measuring cups and spoons

Instructions

Begin by browning the Italian sausage and onion in a 10-inch skillet over medium heat for 6-8 minutes. Stir occasionally, breaking up the sausage as it cooks, until it is no longer pink. Drain off any excess grease. This step develops a rich flavor base for the entire lasagna.
Stir in the Italian-style tomato sauce (undrained), dried basil leaves, and salt into the skillet with the cooked sausage and onion. Mix well to combine all the ingredients, ensuring the sauce is evenly distributed. Simmer for a few minutes to allow the flavors to meld.
In a separate bowl, combine 1 cup of the shredded mozzarella cheese with the part-skim ricotta cheese and grated parmesan cheese. Mix these cheeses thoroughly until well combined. This creates the creamy, cheesy layer that is so essential to a good lasagna.
Refrigerate the remaining 1 cup of mozzarella cheese while the lasagna cooks in the slow cooker. This will be used later to create a melted, gooey topping.
To assemble the lasagna in the slow cooker, spoon 1/4 of the sausage mixture into the bottom of a 6-quart slow cooker. This layer prevents the noodles from sticking and ensures a flavorful base.
Top the sauce layer with 5 uncooked lasagna noodles, breaking them if necessary to fit the shape of your slow cooker. If your slow cooker is round or oval, you may need to break the noodles into smaller pieces to ensure they cover the entire surface.
Spread 1/2 of the cheese mixture evenly over the noodle layer. This layer of creamy cheese provides a delightful contrast to the savory sausage sauce.
Spoon another 1/4 of the sausage mixture over the cheese layer. This ensures that each layer of the lasagna is packed with flavor.
Repeat the layering process: Top with 5 more uncooked lasagna noodles, the remaining cheese mixture, and another 1/4 of the sausage mixture.
Finish with the final 5 uncooked lasagna noodles and the remaining sausage mixture, ensuring that the top layer is completely covered in sauce. This will help to prevent the noodles from drying out during the slow cooking process.
Cover the slow cooker and cook on Low heat setting for 4-6 hours, or until the noodles are tender. The exact cooking time may vary depending on your slow cooker, so it is important to check for doneness periodically. The noodles should be easily pierced with a fork when they are ready.
Once the noodles are tender, sprinkle the top of the lasagna with the remaining 1 cup of shredded mozzarella cheese.
Cover the slow cooker again and let the lasagna stand for about 10 minutes, or until the mozzarella cheese is melted and gooey. This final step adds a beautiful, cheesy topping to the lasagna.
To serve, carefully cut the lasagna straight down into portions. Be mindful when removing the first piece as it can be a little less firm than oven-baked lasagna. Serve hot and enjoy!

Expert Tips & Tricks

Sausage Selection: Don’t be afraid to experiment with different types of Italian sausage. Sweet, mild, hot, or even a blend can add unique character to the dish. For an extra layer of flavor, consider using Italian sausage with fennel seeds already mixed in.
Noodle Placement: To ensure even cooking, make sure the noodles are well submerged in the sauce. If necessary, add a splash of water or broth to the slow cooker to ensure sufficient moisture.
Cheese Boost: For an even richer flavor, consider adding a layer of provolone cheese in addition to the mozzarella and Parmesan.
Herb Enhancement: Fresh herbs can elevate the flavor profile of the lasagna. Consider adding chopped fresh parsley, oregano, or basil to the cheese mixture or as a garnish before serving.
Preventing Stickiness: If you are concerned about the lasagna sticking to the bottom of the slow cooker, you can line it with parchment paper, leaving an overhang to easily lift the lasagna out.

Serving & Storage Suggestions

Serve the Slow Cooker Italian Sausage Lasagna hot, garnished with fresh parsley for added color and freshness. A side of garlic bread or a simple green salad complements the richness of the lasagna perfectly.

To store leftovers, allow the lasagna to cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to 3-4 days. To freeze, wrap individual portions tightly in plastic wrap and then place them in a freezer-safe bag or container. Frozen lasagna can be stored for up to 2-3 months.

To reheat, thaw frozen lasagna in the refrigerator overnight. Reheat in the microwave, oven, or skillet until heated through. If reheating in the oven, cover with foil to prevent the cheese from burning.
