Key Ingredients & Substitutions
Jumbo Pasta Shells: These are essential for holding the filling. If you can’t find them, you can use manicotti shells or even large elbow macaroni as a substitute.
Ground Beef: You can substitute ground turkey or chicken for a lighter version. For a vegetarian option, use lentils or a meatless ground alternative!
Marinara Sauce: Store-bought works well, but you can also use homemade for a fresher taste. If you’re looking for a kick, try adding some crushed red pepper flakes to the sauce!
Ricotta Cheese: Cottage cheese can be a great alternative for more protein. Just blend it for a smoother texture if you prefer.
Cheeses: If you want to switch things up, mozzarella can be replaced with provolone or cheddar. I love using a mix of cheeses for extra flavor!
How Do I Get My Stuffed Shells to Stay Filled?
Stuffing the shells can seem tricky, but here’s a simple way to make it easier:
- Use a piping bag or a zip-top bag with the corner snipped off to fill the shells quickly. It’s a neat trick!
- Be generous with the filling but don’t overstuff; this can cause them to burst during cooking.
- After you arrange the stuffed shells in the slow cooker, spoon sauce generously on top to keep them moist and flavorful.
With these tips, your stuffed shells will come out perfectly filled and oh-so-tasty!

How Much Time Will You Need?
This recipe takes about 20 minutes of prep time and 3 to 4 hours of slow cooking on low. If you’re in a hurry, you can cook it on high for 1.5 to 2 hours. It’s a set-it-and-forget-it kind of meal!
Step-by-Step Instructions:
1. Cook the Jumbo Pasta Shells:
Begin by boiling the jumbo pasta shells according to the package directions until they are al dente. Drain them and rinse under cold water to prevent them from sticking together. Set them aside while you prepare the filling.
2. Prepare the Meat Filling:
In a skillet set over medium heat, cook the ground beef along with the chopped onion and minced garlic. Stir it until the meat is browned and the onion is translucent. Make sure to drain any excess fat before adding 1 cup of marinara sauce. Season with salt and pepper to taste, then remove from heat.
3. Mix the Cheese Filling:
In a large bowl, mix the ricotta cheese, 1 cup of shredded mozzarella, 1/4 cup of Parmesan, the egg, chopped parsley, Italian seasoning, and a little salt and pepper until everything is well combined and smooth.
4. Stuff the Pasta Shells:
Now it’s time to fill the shells! Take each cooked pasta shell and carefully stuff it with the cheese filling mixture. Don’t be shy—fill them up well!
5. Prepare the Slow Cooker:
Lightly grease the inside of your slow cooker with cooking spray or a bit of olive oil to prevent sticking. This will make the cleanup easier too!
6. Layer the Ingredients:
Spread 1 cup of marinara sauce evenly on the bottom of the slow cooker. Next, place the stuffed shells in a single layer over the sauce. Try to arrange them neatly for a pretty presentation!
7. Add the Meat Sauce and More Sauce:
Spoon the prepared meat mixture evenly over the stuffed shells. Then, pour the remaining 1 cup of marinara sauce on top, followed by the rest of the mozzarella and Parmesan cheese.
8. Slow Cook to Perfection:
Cover the slow cooker and cook on LOW for 3-4 hours or on HIGH for about 1.5-2 hours. When it’s done, the cheese should be melted and the sauce bubbly.
9. Finish with a Golden Top (Optional):
If you want that golden, bubbly cheesy topping, transfer the cooked shells to a baking dish and broil them in the oven for 2-3 minutes, watching closely to avoid burning.
10. Serve and Enjoy:
Once ready, sprinkle some additional fresh parsley on top for garnish if you like. Serve up your delicious stuffed shells and enjoy a time of good food and great company!
Now sit back, relax, and enjoy your comforting, hearty slow cooker stuffed shells with meat sauce!
