Ingredients
  

Main Ingredients
  • 1 package (20oz / 567g) frozen four-cheese ravioli Do not thaw before using; frozen goes straight into the slow cooker
  • 1 jar (24oz / 680g) pasta sauce Choose marinara, arrabbiata, or tomato basil sauce that you would happily eat on its own
  • 1 pound (450g) Italian sausage, cooked and drained Brown in a skillet before adding; uncooked sausage releases too much fat
  • 4 cups (450g) shredded mozzarella cheese Full-fat, low-moisture mozzarella melts best

Method
 

Preparation
  1. Brown and drain the Italian sausage in a large skillet over medium-high heat until fully cooked (8–10 minutes). Drain on paper towels.
  2. Spray the inside of the slow cooker insert with non-stick cooking spray or use a liner.
  3. Spread about 1/4 cup of pasta sauce on the bottom of the slow cooker.
Layering
  1. Add one third of the frozen ravioli in a single layer on the sauce.
  2. Spread one third of the cooked sausage over the ravioli.
  3. Spoon one third of the pasta sauce over the sausage and ravioli.
  4. Sprinkle one third of the shredded mozzarella over the sauce.
  5. Repeat the layering process two more times, finishing with mozzarella on top.
Slow Cooking
  1. Place the lid on the slow cooker and cook on LOW for 3–4 hours or HIGH for 2 hours.
  2. Do not lift the lid during cooking.
Serving
  1. Allow the casserole to rest with the lid off for 10 minutes before serving.
  2. Scoop portions of the casserole and garnish with fresh basil, Parmesan, or red pepper flakes if desired.

Notes

Serve with a simple green salad or garlic bread to complement the rich flavors of the casserole. Store leftovers in an airtight container for up to 4 days.
