Ingredients You’ll Need

Meat: Italian sausage, ground beef, ground turkey, or Italian turkey sausage all work beautifully. Italian sausage adds a ton of flavor—my personal favorite for this recipe!
Jumbo pasta shells: Grab them when you see them—these tend to sell out quickly.
Ricotta cheese: Whole milk ricotta gives a richer flavor, but part-skim works too.
Mozzarella cheese: Freshly grated if you can, but pre-shredded works just fine for busy days.
Parmesan cheese: Freshly grated is best—skip the cheap bagged version that doesn’t melt well.
Garlic: Finely minced for that perfect savory bite.
Egg: Helps bind the ricotta mixture.
High-quality marinara sauce: Rao’s is my go-to—rich, flavorful, and tastes homemade.
Seasonings: Kosher salt, freshly ground pepper, Italian seasoning.
Fresh herbs: Flat-leaf parsley and basil for that fresh pop of flavor.

How to Make Slow Cooker Stuffed Shells with Meat

1. Cook Your Meat

Start by browning your Italian sausage (or whichever meat you prefer) in a skillet over medium heat. Break it up with a wooden spoon as it cooks so you get small, crumbled pieces that will mix evenly into the cheese filling. Once the meat is cooked through and no pink remains, drain any excess grease and let the meat cool slightly. Cooling it just a bit helps keep the ricotta mixture from getting runny later.

2. Make the Cheesy Filling

While the meat is cooling, grab a large mixing bowl. Add the ricotta, mozzarella, parmesan, minced garlic, egg, Italian seasoning, salt, pepper, and chopped parsley. Stir everything together until well combined—don’t be afraid to get in there with a sturdy spoon. Once the meat has cooled, fold it into the cheese mixture. The filling should be thick, creamy, and just a little chunky from the meat.

3. Cook and Stuff the Shells

Boil the jumbo pasta shells in salted water until they are just al dente—this is super important since they’ll finish cooking in the slow cooker. Drain them and let them cool slightly so they’re easier to handle. Using a spoon, carefully fill each shell with about 2 tablespoons of the cheesy meat mixture. If the shells tear a little, don’t worry—they’ll still taste amazing!

4. Layer in the Slow Cooker

Spread a thin layer of marinara sauce on the bottom of your slow cooker. Arrange the stuffed shells in a single layer on top of the sauce. If you have more shells, add another layer of sauce, then more shells, and continue until everything is in. Finish with a generous layer of marinara and a final sprinkle of mozzarella cheese over the top.

5. Cook Low and Slow

Cover the slow cooker with the lid and set it on LOW for 3-4 hours. The shells will get tender, the cheese will melt into gooey perfection, and the sauce will bubble up around them. Right before serving, top with fresh basil or extra parmesan for that restaurant-worthy touch.

When it’s finally time to dig in, you’ll have tender shells, cheesy filling, and saucy goodness all in one bite. And the best part? You barely lifted a finger to make it happen.

Helpful Tips for Success

Don’t overcook the shells! They’ll keep cooking in the slow cooker, so slightly undercooked pasta is key.
Go big on sauce: These shells soak up sauce as they cook, so don’t skimp.
Make it ahead: You can assemble everything the night before and store it in the fridge. Just pop it in the slow cooker when you’re ready.
