Our slow-cooker lasagna is a comforting dinner to come home to—or to leave to slow cook for four to six hours while you're at home. The meat sauce is a delicious combination of ground sirloin and Italian sausage, the sausage brings fat and seasoned flavors to the beef, so making the sauce is a snap. You will need to sauté the sauce on the stovetop before you assemble the lasagna in the slow cooker. But there's no need to buy no-boil noodles or to cook the lasagna sheets before assembling, they cook as the lasagna cooks—that's just part of the magic of slow-cooker lasagna.
Directions
-
Saute meats:
In a 5-quart Dutch oven or heavy pot, cook sausage and beef over medium-high, breaking up meat with a spoon, until no longer pink, 4 to 6 minutes.
-
Add vegetables and garlic:
Add onion, carrots, and garlic; season with salt and pepper. Cook until onion has softened, 3 to 5 minutes.
-
Add tomato paste, then tomatoes:
Stir in tomato paste, then tomatoes; bring to a boil, and remove from heat.
-
Assemble lasagna:
Spoon 2 cups meat mixture into bottom of a 5- to 6-quart slow cooker. Layer 3 noodles (breaking them as needed to fit), 2 cups meat mixture, and 1/2 cup cheese; repeat with two more layers (refrigerate 1/2 cup cheese for topping).
To fit lasagna noodles into a round slow cooker, break off corners as needed. You don't have to precook the noodles. When the lasagna's done, they'll be ready, too.
-
Cook lasagna:
Cover slow cooker, and cook on low, 4 to 6 hours.
-
Add reserved cheese:
Sprinkle lasagna with 1/2 cup cheese. Cover until cheese has melted, about 10 minutes.
