This easy Crockpot Lasagna recipe is a simple way to enjoy classic lasagna without the hassle. Just layer the ingredients in your slow cooker, let it cook for 4 hours and enjoy a delicious, hands-off meal! Super cheesy - made with mozzarella, ricotta and Parmesan cheeses!
In a large skillet over medium heat, cook sausage, onion and garlic together until sausage is browned. Drain any grease from the pan.
Add marinara sauce, tomato paste, salt and oregano into the pan and stir until well mixed.
In a large bowl add mozzarella, ricotta and parmesan cheese together mixing well.
Add a couple spoonfuls of the sauce mixture to the bottom of the crockpot to cover it.
Spread about 1/3 of the noodles into the bottom of the crockpot. You will need to break some of the noodles to fit and cover accordingly.
Add 1/3 of the sauce mixture on top of the noodles. Super important: the sauce needs to completely cover the noodles, every single inch of them - this is the way the noodles are going to cook!
Add 1/3 of the cheese mixture on top of the sauce.
Repeat 2 more layers of noodles, sauce and cheese until all the ingredients are used.
Cover the lid and cook on LOW for 4 hours or until lasagna noodles are tender. If needed, cook in 30-minute increments until noodles are fully cooked and tender. 4 hours is plenty for us, but depending on the crockpot it can take 4-5 hours. Serve and enjoy!
