  • 28 oz can crushed tomatoes
  • 8 oz tomato sauce
  • 1 teaspoon kosher salt
  • ½ teaspoon freshly ground black pepper

For the Cheese Filling

  • 15 oz ricotta cheese
  • 2 cups shredded mozzarella cheese, divided
  • 1 cup shredded provolone (or fontina)
  • ½ cup grated parmesan cheese
  • 2 cloves garlic, minced
  • 1 egg

How to Make Slow Cooker Stuffed Shells with Meat

Step 1: Build the Flavorful Meat Sauce

In a skillet over medium heat, warm the olive oil and sauté the onion until soft. Add garlic and crushed red pepper, cooking just until fragrant.
Add the ground meat and cook until browned, breaking it up as it cooks. Stir in crushed tomatoes, tomato sauce, salt, and pepper. Let it simmer for about 10–15 minutes. This step gives the sauce that slow-simmered taste without waiting all day.

(Your kitchen will already smell amazing at this point.)

Step 2: Mix the Cheesy Filling

In a large bowl, combine ricotta, 1 cup mozzarella, provolone, parmesan, egg, garlic, salt, pepper, and parsley. Mix until smooth and creamy.
Transfer the filling to a gallon-size zip-top bag and snip off one corner—this makes stuffing shells so much easier and way less messy.

Step 3: Stuff the Shells

Carefully pipe the cheese mixture into the uncooked pasta shells. Don’t overfill—think “comfortably full,” not bursting at the seams.

Step 4: Layer Everything in the Slow Cooker

Spread about 1 cup of meat sauce on the bottom of your slow cooker. Arrange the stuffed shells in a single layer (a little overlap is okay).
Top with the remaining sauce, sprinkle with the rest of the mozzarella, and gently pour the water around the edges—this helps the pasta cook perfectly.

Step 5: Let the Slow Cooker Do Its Thing

Cover and cook:

  • LOW for 4–5 hours, or
  • HIGH for 2–3 hours

The shells should be tender, and the cheese bubbly and irresistible.
