Slow-Cooker Meatball Sandwiches are a delicious and hassle-free way to enjoy a classic comfort food favorite. These sandwiches feature juicy, flavorful meatballs simmered to perfection in a rich marinara sauce, all thanks to the convenience of a slow cooker. The slow-cooking process allows the meatballs to absorb all the savory flavors of the sauce, resulting in a tender, melt-in-your-mouth texture. Pile the meatballs onto toasted hoagie rolls, sprinkle with mozzarella or provolone cheese, and broil until bubbly and golden for a satisfying meal. Perfect for game days, family dinners, or casual gatherings, these Slow-Cooker Meatball Sandwiches are sure to be a hit with everyone.
Ingredients:
- 1 1/2 pounds ground beef
- 1/2 cup breadcrumbs
- 1/4 cup grated Parmesan cheese
- 1/4 cup milk
- 1 large egg
- 2 cloves garlic, minced
- 1 teaspoon Italian seasoning
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 jar (24 ounces) marinara sauce
- 6 hoagie rolls or sub rolls
- 1 1/2 cups shredded mozzarella or provolone cheese
- Fresh basil or parsley, chopped (optional, for garnish)
Instructions:
- Prepare the Meatballs:
- In a large mixing bowl, combine the ground beef, breadcrumbs, grated Parmesan cheese, milk, egg, minced garlic, Italian seasoning, salt, and black pepper. Mix well until all ingredients are thoroughly combined.
- Form the Meatballs:
- Shape the meat mixture into 1 1/2-inch meatballs (about the size of a golf ball). You should have around 18-20 meatballs.
- Arrange in the Slow Cooker:
- Place the meatballs in the bottom of a slow cooker. Pour the marinara sauce over the meatballs, making sure they are all coated with the sauce.
- Cook the Meatballs:
- Cover the slow cooker and cook on low for 4-5 hours, or on high for 2-3 hours, until the meatballs are cooked through and tender.
- Assemble the Sandwiches:
- Preheat your broiler. Slice the hoagie rolls lengthwise and place them on a baking sheet. Spoon 3-4 meatballs into each roll, along with some of the marinara sauce. Sprinkle the shredded mozzarella or provolone cheese over the top of each sandwich.
- Broil the Sandwiches:
- Place the baking sheet under the broiler and broil for 2-3 minutes, or until the cheese is melted, bubbly, and golden brown. Keep a close eye on them to prevent burning.
- Serve:
- Remove the sandwiches from the oven and garnish with fresh chopped basil or parsley, if desired. Serve the Slow-Cooker Meatball Sandwiches hot, with extra marinara sauce on the side for dipping.
Slow-Cooker Meatball Sandwiches are a satisfying and easy meal that combines the rich flavors of homemade meatballs with the convenience of a slow cooker. Whether for a quick family dinner or a crowd-pleasing game-day snack, these cheesy, saucy sandwiches are sure to be a hit!
