Enjoy easy and delicious Crockpot Stuffed Shells, a classic Italian dish perfect for dinner! This simple recipe features pasta shells filled with a creamy ricotta blend and slow-cooked in marinara sauce for an easy meal with little effort using the help of your slow cooker!
Cook shells until they're firm but not too soft. Then, rinse them in cold water and drain thoroughly.
Add ricotta cheese, frozen spinach, 1½ cups mozzarella cheese, parmesan cheese, eggs, Italian seasoning, salt, black pepper, and garlic in a large bowl. Mix until well combined. Stuff filling into the shells.
Add ½ cup of pasta sauce to the bottom of a 6-quart slow cooker. Place half of the stuffed shells on the bottom and pour 1 cup of pasta sauce over the top. Add the remaining stuffed shells and pour the remaining pasta sauce over the top. Sprinkle the remaining mozzarella cheese over the top.
Sprinkle the remaining mozzarella cheese over the top and cook on high for 2-3 hours or on low for 3-4 hours.
