I love how I can just toss everything in the slow cooker and let it do the work while I relax. Perfect for busy days when I want a tasty meal without fuss!
Key Ingredients & Substitutions
Pasta Shells: Use large pasta shells for the best results. If you can’t find them, jumbo pasta shells or even cannelloni can work in a pinch!
Ground Beef: I love using ground beef for its rich flavor. If you want a lighter option, try ground turkey or chicken instead. For a vegetarian version, make a filling using mushrooms or lentils.
Ricotta Cheese: This is the star for creamy filling. If ricotta is not available, cottage cheese can be a healthier substitute; just blend it for a smoother texture.
Marinara Sauce: Use your favorite jarred sauce or homemade if you have it. For a bit of heat, add crushed red pepper flakes to the sauce.
What’s the Best Way to Stuff the Shells Properly?
Stuffing the shells can be tricky! Here’s a simple method to get it right:
- Use a teaspoon or small spatula for filling the shells, making sure to fill them generously but not overstuff.
- Alternatively, you can place the filling in a piping bag (or a zip-top bag with the corner snipped off) for a neater process.
- Gently place the stuffed shells seam side up in the slow cooker to help them keep their shape.
With these tips, you’ll fill those shells like a pro!

How Much Time Will You Need?
This recipe takes about 30 minutes of prep time and then 3 to 4 hours of cooking time in the slow cooker. Overall, you’ll have a delicious meal ready in about 4 to 5 hours!
Step-by-Step Instructions:
1. Prepare the Pasta:
Start by cooking the large pasta shells according to the package instructions until they’re al dente—this means they should still be a bit firm. Once cooked, drain them well and rinse under cold water to stop the cooking process and prevent sticking. Set them aside for later.
2. Cook the Meat:
In a skillet over medium heat, add a drizzle of olive oil. Throw in the chopped onion and cook it until it’s nice and translucent, which will take about 3-4 minutes. Next, add the minced garlic and let it cook for another minute until fragrant.
Now, add the ground beef to the skillet, seasoning it with salt and pepper. Cook until the beef is browned all the way through, making sure to break it up into smaller pieces. If there’s too much fat, drain it off for a leaner filling.
3. Assemble the Slow Cooker:
Pour half of the marinara sauce into the bottom of the slow cooker to prevent sticking and add flavor.
4. Mix the Cheese Filling:
In a mixing bowl, combine the ricotta cheese, half of the shredded mozzarella, grated Parmesan, egg, chopped parsley, Italian seasoning, and a good pinch of salt and pepper. Mix everything together until it’s well combined.
5. Stuff the Shells:
Now, carefully stuff each cooked pasta shell with the cheesy meat mixture. Place the stuffed shells seam side up in the slow cooker, right on top of the marinara sauce.
6. Add the Sauce and Cheese:
Once all the shells are neatly arranged, pour the remaining marinara sauce evenly over them. Finally, sprinkle the rest of the shredded mozzarella cheese layered right on top.
7. Cook Until Perfect:
Cover the slow cooker with its lid and cook on low for about 3 to 4 hours. The shells will be bubbly and wonderful when they’re done!
8. Serve and Enjoy:
Before serving, feel free to garnish your stuffed shells with additional chopped parsley or a sprinkle of grated Parmesan for a lovely finishing touch. Enjoy your comforting and cheesy Slow Cooker Stuffed Shells with Meat Sauce!
