Ingredients
For the Meatballs:
- 2 lbs Lean Ground Beef (80/20)
- 1 cup Panko Breadcrumbs
- 2 Eggs, lightly beaten
- 1/2 Yellow Onion, finely grated
- 2 cloves Garlic, minced
- 1 teaspoon Salt
- 1/2 teaspoon Black Pepper
For the BBQ Sauce:
- 2 cups BBQ Sauce (your favorite kind)
- 1 Yellow Onion, chopped
- 1 cup Beef Broth
- 1/4 cup Brown Sugar, packed
- 2 tablespoons Worcestershire Sauce
For the Subs:
- 8 Hoagie or Sub Rolls
- 8 slices Provolone or Mozzarella Cheese
Step-by-Step Instructions
- Make the Meatball Mixture: In a large bowl, gently combine the ground beef, panko breadcrumbs, eggs, grated onion, minced garlic, salt, and pepper. Be careful not to overmix. Roll the mixture into 1.5- to 2-inch meatballs.
- Arrange in Slow Cooker: Place the raw meatballs in the bottom of your slow cooker.
- Make the Sauce: In a medium bowl, whisk together the BBQ sauce, chopped onion, beef broth, brown sugar, and Worcestershire sauce.
- Slow Cook: Pour the sauce mixture over the meatballs in the slow cooker. Cover and cook on LOW for 4-6 hours or on HIGH for 2-3 hours, until the meatballs are cooked through and tender.
- Assemble the Subs: Preheat your broiler. Slice the hoagie rolls open, place them on a baking sheet, and toast them lightly under the broiler for 1-2 minutes.
- Melt and Serve: Spoon 3-4 meatballs and a generous amount of sauce into each toasted roll. Top with a slice of provolone cheese. Place the subs back under the broiler for another 1-2 minutes, or until the cheese is melted and bubbly. Serve immediately.
Tips & Variations
- Pro Tip: For an even deeper flavor, you can sear the meatballs in a hot skillet with a little oil before adding them to the slow cooker. This step is optional but adds a great crust.
- Make it Spicy: Add 1/2 teaspoon of red pepper flakes or a finely diced jalapeño to the BBQ sauce for a spicy kick.
- Add Bacon: For a smokier flavor, add 4-6 slices of cooked, crumbled bacon to the slow cooker with the sauce.
- Different Meat: A mix of ground beef and ground pork makes for extra juicy meatballs. Ground turkey also works well.
