How to Make Slow Cooker Stuffed Shells with Meat

Prepare Marinara Sauce: Begin by heating olive oil in a sauté pan over medium heat. Add the finely diced onion and cook until softened, about 5-7 minutes. Stir in minced garlic and crushed red pepper, cooking for another minute until fragrant. Mix in the crushed tomatoes and tomato sauce, seasoning with salt and pepper. Let it simmer for 20 minutes, stirring occasionally.
Make the Filling: In a large bowl, combine ground meat, ricotta cheese, 1 cup of shredded mozzarella, grated parmesan, egg, minced garlic, salt, pepper, and chopped parsley. Mix until well combined and transfer the mixture into a large zip-top bag. Snip a corner of the bag for easy filling.
Assemble Shells: Spray a 9×13 baking dish with non-stick spray. Spread 1 cup of the marinara sauce in the bottom of the dish. Fill each uncooked jumbo shell with the meat and cheese filling, then place them in a single layer in the dish. Top with the remaining marinara sauce and sprinkle the remaining mozzarella over the shells, pouring water around them.
Cook: Cover the dish tightly with foil to trap steam. Place the dish in your slow cooker and cook on high for about 1 hour or until the shells are tender. Uncover them for the last 1-2 minutes to let the cheese melt and turn slightly golden.
Serve: Carefully remove the shells from the slow cooker and plate them up. Garnish with fresh parsley or basil before serving for a burst of color and flavor.

Optional: Drizzle with extra marinara sauce before serving for an added touch!

Slow Cooker Stuffed Shells with Meat Recipe FAQs

How do I choose the right pasta shells?
Absolutely! Look for jumbo pasta shells to ensure they hold the filling well. Avoid any with visible cracks or dark spots. If you’re aiming for something different, manicotti can be a great substitute, giving a fun twist to the classic dish.

How should I store leftovers?
You can store any leftover stuffed shells in an airtight container in the refrigerator for up to 3 days. Just make sure they’re cooled down to room temperature before sealing them. For the best texture when you reheat them, I recommend using the oven—wrap them in foil and heat at 350°F (175°C) for about 20-25 minutes!

Can I freeze Slow Cooker Stuffed Shells with Meat?
Definitely! To freeze, prepare the shells but don’t cook them. Place the filled shells in a single layer on a baking sheet to flash freeze for 1-2 hours, then transfer them to a tightly sealed container or freezer bag. You can freeze them for up to 3 months. When you’re ready to cook, simply thaw them in the fridge overnight and follow the cooking instructions.

What should I do if my sauce is too watery?
Very good question! If you find your marinara sauce is too watery after cooking, try simmering it on the stovetop for a few minutes to thicken it up before pouring over the pasta. Alternatively, if it seems too thin during the assembly, you can add a tablespoon or two of tomato paste to help absorb some excess liquid!

Are there any dietary considerations with the ingredients?
Certainly! This recipe can be easily adjusted for dietary restrictions. For a gluten-free option, use gluten-free pasta shells and ensure your marinara sauce is safe. If you’re looking for a lower-fat version, consider using ground turkey or chicken, and cottage cheese instead of ricotta. As always, check for potential allergies, especially with ingredients like cheese and eggs, and feel free to swap as needed.

What can I do to elevate the flavors of my stuffed shells?
The more the merrier! Enhance the flavors by adding sautéed vegetables like spinach, mushrooms, or zucchini into the filling mix. Moreover, consider blending different cheeses like gouda or adding some Italian seasoning to the meat for the refilling. Experiment with herbs like fresh basil or a sprinkle of nutmeg for depth; those little touches can take your Slow Cooker Stuffed Shells with Meat to a whole new level!
