Lasagna is a timeless comfort food, but the traditional oven method can take a lot of time and effort. This slow cooker version makes it incredibly easy to enjoy all the rich, cheesy, saucy goodness of homemade lasagna with less hands-on cooking and no need to heat up the entire kitchen. Whether you’re hosting guests or just feeding your family on a busy night, this Crockpot Lasagna delivers a cozy, satisfying meal that requires minimal prep and cleanup.
Layered with tender noodles, savory Italian sausage, creamy marinara, and a perfect blend of mozzarella and Parmesan cheese, this lasagna comes together in a few simple steps. You don’t need special ingredients or fancy tools—just your slow cooker and basic pantry staples. Plus, the slow simmer in the crockpot helps the flavors meld beautifully while keeping the pasta soft but not mushy.
What’s even better? This version allows you to walk away while dinner practically makes itself. By the time it’s done, you’ll have a warm, bubbly, cheesy lasagna ready to serve straight from the crockpot. It’s classic comfort food made weeknight-easy—and once you try it, you might never go back to the oven version again.
Ingredients (Serves 6)
375 grams (¾ lb) Italian sausage (mild or spicy)
1 small onion, finely diced
2½ cups marinara sauce
1 teaspoon dried oregano
½ teaspoon salt
¼ teaspoon black pepper
9 regular lasagna noodles (not oven-ready)
2 cups shredded mozzarella cheese
3 tablespoons shredded Parmesan cheese
Instructions
In a medium skillet over medium-high heat, cook the sausage and diced onion until the meat is fully browned. Stir in the marinara sauce, oregano, salt, and black pepper. Lightly grease a 2.5 to 4-quart oval slow cooker (avoid deep round ones if possible for better layering). Spread a spoonful of sauce on the bottom to prevent sticking. Break 3 noodles to fit and lay them down in a single layer. Spread 1/3 of the sauce mixture over the noodles, followed by 1/3 of the mozzarella and Parmesan. Repeat this layering process two more times. If you have extra noodles and sauce, you can add a fourth layer. Cover and cook on low for 2.5 to 3 hours, or until the noodles are soft. Once done, turn off the heat and let the lasagna sit for 10 minutes before slicing and serving.
Nutritional and Dietary Notes
This dish is high in protein thanks to the sausage and cheese, and it provides a decent amount of calcium and energy from the dairy and pasta. It’s rich, filling, and comforting—perfect as a main course. If you’re watching your sodium or fat intake, consider using lean sausage and low-sodium marinara. Gluten-free noodles and plant-based cheese alternatives can make this recipe adaptable for gluten-sensitive or dairy-free diets, though flavor and texture may vary slightly.
