Our easy Meatball Subs recipe has homemade flavorful meatballs on a toasted bun with melted provolone cheese and an easy Italian marinara sauce. It's the perfect comfort meal that's freezer friendly and easy to feed a large group.
Meatballs: In a large bowl combine all of the meatball ingredients together EXCEPT for the meat; saltines, beef broth, parley, egg, oregano, garlic powder, salt, pepper, basil, crushed red pepper. Stir and rest for 10 minutes so the crackers can soak up the liquid. Add the meat and mix just until combined (don't over mix).
Preheat oven to 400 degrees F. Grease a baking sheet, or line with aluminum foil.
Form 15 meatballs, about the size of golf balls, and gently sprinkle them all around with flour. Place the meatballs one inch apart on the baking sheet and bake for 20 -25 minutes or until cooked through.
Sauce: Add sauce ingredients to a saucepan and stir to combine. Simmer for 10-15 minutes. When the meatballs are finished baking, transfer them to the sauce.
Assemble: Slice the hoagie rolls in half and layer each with 2 slices cheese. Broil on high for 2-3 minutes or until rolls are toasted and cheese is melted. Remove from oven. Place 3 meatballs on each sub, followed by a large spoonful of sauce. Serve immediately.
