Ingredients

For the Shells

• 24 jumbo pasta shells

• 1 pound lean ground beef

• 1 small onion, finely diced

• 3 cloves garlic, minced

• 1 teaspoon Italian seasoning

• ½ teaspoon salt

• ½ teaspoon black pepper

Cheese Filling

• 1 cup ricotta cheese

• 1 cup shredded mozzarella cheese

• ½ cup grated Parmesan cheese

• 1 large egg

• 2 tablespoons fresh parsley, chopped

Sauce

• 4 cups marinara sauce

• 1 teaspoon Italian seasoning

Topping

• 2 cups shredded mozzarella cheese

• Extra Parmesan cheese, for garnish

• Fresh parsley, for garnish

Instructions

Step 1: Cook the Pasta

Cook the jumbo shells according to the package directions, but stop cooking a minute or two early so they're slightly undercooked. Drain and let them cool enough to handle.

Step 2: Prepare the Filling

In a large skillet over medium heat, cook the ground beef and diced onion until the beef is browned and the onion is softened. Add the minced garlic, Italian seasoning, salt, and pepper, and cook for another minute until fragrant. Remove from heat.

Step 3: Mix the Cheese

In a mixing bowl, combine the ricotta, mozzarella, Parmesan, egg, and fresh parsley. Stir until smooth and well blended. Fold in the cooked beef mixture until fully incorporated.

Step 4: Stuff the Shells

Carefully fill each cooked shell with the beef and cheese mixture. Don't overstuff—just fill them generously but evenly.

Step 5: Assemble in the Crockpot

Spread a thin layer of marinara sauce over the bottom of your slow cooker. Arrange the stuffed shells in a single layer on top of the sauce. Pour the remaining marinara sauce over the shells, making sure they're well coated.

Step 6: Slow Cook

Cover the crockpot and cook on LOW for 4 to 5 hours, until the shells are tender and the filling is hot and bubbly.

Step 7: Add the Cheese

During the last 20 minutes of cooking, sprinkle the remaining 2 cups of shredded mozzarella over the top. Cover and let it melt until golden and gooey.

Step 8: Serve

Garnish with extra Parmesan and fresh parsley. Serve warm and enjoy!

Tips for Success

• Partially cook the shells so they hold their shape during slow cooking.

• Use freshly shredded mozzarella for the creamiest, meltiest topping.

• Avoid overfilling the shells—they expand slightly as they cook.

• Add extra sauce if you prefer a saucier dish; you can always add more before serving.

Storage Instructions

Refrigerator: Store leftovers in an airtight container for up to 4 days.

Delicious Variations
