Slow Cooker Sausage Lasagna is a one pot dinner layered with meat, cheese, pasta and the best tomato sauce. Crockpot lasagna with lasagna noodles is so easy!
Add the sausage to a large skillet and heat over medium high heat. Stir in the diced onions and cook until the sausage is browned, breaking up the sausage as it cooks. Drain off any excess grease from the pan.
Then add in the minced garlic and cook for 1 minute until the garlic is aromatic. Then add in the tomato sauce, Italian Seasoning, salt and pepper. Stir and cook for 7-8 minutes until heated through and well combined. Then remove the pan from the heat.
In a separate bowl, stir together the ricotta cheese, 1 ½ cups mozzarella cheese and Parmesan Cheese.
Spray a 6 quart crock pot with non-stick cooking spray. Then pour a layer of sauce on the bottom of the crock pot (approximately 1-1 ½ cups). Then place a layer of the lasagna noodles on top. It’s ok to break some of the noodles to cover the top of the sauce. Then layer approximately ? of the cheese mixture on top followed by approximately 1 cup of the sausage mixture.
Repeat these layers 2 more times making sure to end with the meat sauce. Sprinkle the remaining ½ cup of the mozzarella cheese on top.
Cover and cook the lasagna on low for 4-5 hours until the noodles are soft.
Then turn the crock pot off and let the lasagna rest for 20-30 minutes before serving. Then the lasagna is ready to serve and enjoy!
