Ingredients
Method
To Make the Meatballs:
- Preheat the oven to 450°F. Grease a rimmed baking sheet with canola oil.
- In a large mixing bowl, beat the egg and water lightly with a fork.
- Add the minced onion, garlic, breadcrumbs, Parmesan cheese, Italian seasoning, garlic powder, salt, and pepper. Mix well.
- Fold in the ground beef gently, being careful not to over-mix.
- Shape the mixture into 1½-inch meatballs and place them on the prepared baking sheet.
- Bake for 10–12 minutes, or until the meatballs are cooked through and reach an internal temperature of 160°F.
To Make the Meatball Subs:
- In a medium saucepan, combine the baked meatballs and marinara sauce. Cover and heat over medium-low heat for 5–10 minutes until warmed through.
- Split the hoagie rolls and place them cut-side up on a baking sheet. Broil for about 2 minutes, or until the edges are lightly toasted.
- Add a layer of shredded or sliced cheese to the bottom half of each roll to prevent the bread from becoming soggy.
- Use a slotted spoon to place 4 meatballs into each roll. Spoon additional marinara sauce over the meatballs and top with more cheese.
- Broil the assembled subs for another 2 minutes, or until the cheese is melted and bubbly.
- Serve immediately and enjoy!
Notes
- Meatball Size: Keep meatballs uniform in size for even cooking.
- Make-Ahead Tip: Prepare and bake the meatballs ahead of time, then store them in the refrigerator or freezer.
- Customization: Add a sprinkle of red pepper flakes or fresh basil for extra flavor.
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat the meatballs and sauce separately before assembling the subs.
