Making crockpot lasagna allows me to have a delicious, homemade meal with minimal effort. The slow-cooking process infuses all the flavors together, resulting in a comforting dish perfect for busy weeknights or weekend gatherings.
Saute the Aromatics – In a large pot or Dutch oven, heat olive oil over medium-low heat. Sauté the onions until translucent, about 2 minutes. Add garlic, and cook for 30 seconds.
Brown the Meat – Add the beef and sausage to the pan. Turn the heat to medium-high, break into smaller pieces. Cook until no pink remains, about 3 to 5 minutes. Stir in the salt, Italian seasoning, and black pepper.
Make the Meat Sauce – Add the marinara sauce and 1 cup of water to the pan. Stir to combine, simmer over medium-low heat for 10 minutes. Turn off the heat and set aside.
Make the Cheese Mixture – In a medium bowl, combine ricotta cheese, parmesan cheese, and chopped parsley. Set aside.
Layer the Lasagna – Reserve 2 cups of meat sauce and 1 cup of grated mozzarella cheese. Lightly grease the bottom and sides of a 6-quart slow cooker with olive oil or cooking spray. Add 1 cup of meat sauce to cover the bottom of the dish to prevent sticking. Layer 3 sheets of the dried lasagna noodles, breaking up the pieces to cover any gaps. Evenly add ⅓ of the ricotta cheese mixture, ⅓ of the mozzarella cheese, and ⅓ meat sauce. Repeat for 2 more layers. On the top layer, pour on the 1 cup of reserved meat sauce. Pour 1/2 cup of water along the sides of the pot.
Slow Cook the Lasagna – Cover and cook for 3 ½ to 4 hours on the Low setting. The noodles should be tender, with most of the liquid absorbed.
Add More Cheese – Before serving, sprinkle 1 cup of the reserved mozzarella cheese on top. Cook on Low setting until melted, about 15 minutes.
To Serve – If desired, garnish with parsley. Serve warm.
Notes
Make-Ahead: The meat sauce and cheese filling can be made and refrigerated 2 days in advance. Reheat the sauce before assembling. Alternatively, the lasagna can be assembled 2 days in advance. Add 1 to 1 1/2 hours of cooking to account for the cold insert and ingredients.
Storing:Refrigerate for up to 5 days. Freeze for up to 3 months, defrost before reheating.
Reheating: Reheat slices in the microwave until warmed through, about 1 to 1 ½ minutes.
