Tips for success
If you prefer a more robust flavor, add a pinch of red pepper flakes or some fresh herbs like basil directly into the sauce before cooking. These additions will infuse the entire dish with a subtle heat or aromatic brightness that complements the rich tomato base of the marinara and the savory profile of the meatballs.
For a slightly more golden finish, you can transfer the mixture to an oven-safe baking dish after the slow cooker step and place it under the broiler for two minutes.
This will bubble and lightly brown the mozzarella, providing a beautiful, toasted texture that contrasts wonderfully with the soft, tender pasta and meatballs hidden underneath.
Variations
- Spicy Arrabbiata Twist: Add a tablespoon of crushed red pepper flakes or use a spicy arrabbiata sauce instead of plain marinara to introduce a pleasant kick to the dish.
- Vegetable Medley: Toss in a cup of frozen peas or chopped spinach during the final 30 minutes of cooking to incorporate more texture and color into the meal.
Storage and make-ahead
- Fridge
- Store in an airtight container for up to 3 days.
- Freezer
- Store in a freezer-safe container for up to 2 months. Thaw in the refrigerator overnight before reheating.
- Reheat
- Reheat in the microwave in 1-minute intervals until piping hot, or in a saucepan over medium heat until warmed through.
Transfer any leftovers to an airtight container within 2 hours of cooking. Once cooled, seal the container and place it in the refrigerator. It is important not to leave the food out for more than two hours to ensure safety.
Once sealed, the pasta can be kept in the refrigerator for up to three days. When ready to eat, reheat gently in the microwave or on the stovetop, adding a small amount of water to loosen the sauce.
You can prepare the meatball and pasta base ahead of time and store it in the refrigerator for up to 24 hours before cooking. Simply assemble the ingredients in the slow cooker basin, cover, and keep chilled.
When you are ready to cook, remove the basin from the fridge, let it sit for 15 minutes to take the chill off, then start the slow cooker as directed in the recipe.
Serving ideas
Serve this dish directly from the slow cooker for a casual, family-style presentation. Use a large serving spoon to scoop portions, ensuring everyone gets a good mix of meatballs, pasta, and the cheesy, saucy top layer. It pairs beautifully with a simple side salad or a piece of crusty bread to soak up any remaining marinara sauce.
For an elevated presentation, plate individual servings and garnish with a sprinkle of fresh parsley or an extra dusting of parmesan cheese.
The vibrant colors of the herbs add a fresh finish that complements the deep, rich flavors of the slow-cooked meal. Serve immediately while the cheese is still warm and stretchy to ensure the best possible dining experience.

Easy Crockpot Meatball Mozzarella Penne

Ingredients
- 1 lb Italian meatballs
- 1 lb penne pasta, uncooked
- 1 packet spaghetti seasoning
- 24 oz marinara sauce
- 2 cups shredded mozzarella cheese
Instructions
- Place the Italian meatballs in the bottom of the slow cooker basin. Scatter the dry, uncooked penne pasta evenly over the top of the meatballs to ensure even distribution during the cooking process.
- Sprinkle the entire packet of spaghetti seasoning over the pasta. Pour the marinara sauce over the top of the seasoning and pasta, ensuring all the pasta is covered by the sauce to prevent drying out during the long cook time.
- Cover the slow cooker and cook on low for 4 hours. Once the meatballs reach a safe internal temperature of 160°F (71°C), sprinkle the mozzarella cheese over the top, cover again, and let it sit for 5 minutes until the cheese is perfectly melted and stretchy.
