This crock pot spinach lasagna recipe has delicious layers of cheese, savory spinach, tomato sauce, and tender lasagna noodles. Add everything to the pot, and cook!
Grease the crock pot. Lightly coat the inside of the crock pot or slow cooker with cooking spray.
Add tomato sauce. Spread 1 cup tomato sauce on the bottom of the pot. Arrange a layer of the no-boil lasagna noodles over the sauce. Set aside.
Make the ricotta filling. In a large mixing bowl, combine ricotta cheese, feta cheese, salt, pepper, chopped garlic, Italian seasoning, parsley, oregano, and eggs. Mix until thoroughly combined. Add the fresh spinach and mix until well incorporated.
Assemble. Spread 1/3 of the ricotta mixture over the pasta. Sprinkle a layer of mozzarella and 1/3 of the parmesan cheese over top. Top with a cup of tomato sauce. Repeat these layers until all the ingredients have been used up.
Add a final layer. Top the lasagna with a layer of lasagna noodles covered with tomato sauce and sprinkled with mozzarella and parmesan cheese.
Cook. Cover and cook on HIGH for 3.5 to 4 hours.
Rest. Afterward, turn off the crock pot and let it rest for 45 minutes, or until all the liquid is absorbed. Cut and serve.
