Transform simple ingredients into the ultimate comfort food with these homemade meatball subs. Juicy, perfectly seasoned meatballs nestle into toasted rolls with marinara sauce and melted cheese, creating a satisfying meal that's easier than you might think. These subs bring together the best of Italian-American comfort food in a weeknight-friendly format.
Through years of making these subs, I've learned that the secret lies in well-seasoned meatballs and proper sauce consistency. Each component plays a crucial role in creating the perfect bite.
Essential Ingredients
- Ground Beef: 80/20 for juiciest meatballs
- Panko Breadcrumbs: Creates tender texture
- Fresh Garlic: Minced just before using
- Quality Marinara: Not too thick or thin
- Italian Sub Rolls: Sturdy enough to hold filling
- Fresh Mozzarella: For best melting
Detailed Instructions
- 1. Meatball Creation:
- Combine 1 pound ground beef, ½ cup panko, 2 minced garlic cloves, 1 beaten egg, and Italian seasonings in large bowl. Mix gently with hands until just combined - overmixing makes tough meatballs. Form into golf ball-sized portions (about 2 ounces each). Place on parchment-lined baking sheet while working.
- 2. Browning Process:
- Heat 2 tablespoons olive oil in large skillet over medium-high heat. Brown meatballs in batches, 3-4 minutes per side until golden brown. Don't overcrowd pan - leave space between meatballs. They should sizzle when added to pan.
- 3. Sauce Integration:
- Add 2 cups marinara sauce to skillet with meatballs. Reduce heat to medium-low, cover, and simmer 15-20 minutes until meatballs are cooked through (165°F internal temperature). Sauce should coat meatballs nicely - add water if too thick or simmer longer if too thin.
- 4. Roll Preparation:
- Position oven rack 6 inches below broiler element. Preheat broiler. Split rolls lengthwise, leaving hinge intact. Toast cut sides under broiler 1-2 minutes until lightly golden. Watch carefully to prevent burning.
- 5. Final Assembly:
- Place 3-4 meatballs on each roll bottom. Spoon extra sauce over meatballs. Top with sliced mozzarella and any additional toppings. Broil 2-3 minutes until cheese is melted and bubbly with light golden spots.

Serving & Storage Strategy
Serve subs immediately while cheese is hot and melty. For meal prep, store meatballs and sauce separately from rolls up to 4 days in refrigerator. Reheat meatballs and sauce in skillet over medium heat before assembling. Fresh rolls make all the difference - purchase day of serving if possible.
Perfect Pairings
These hearty subs pair beautifully with classic Italian sides. A crisp Caesar salad cuts through the richness, while garlic knots soak up extra sauce. For casual entertaining, serve with crispy potato chips or sweet potato fries. A simple antipasto platter of olives, pepperoncini, and marinated vegetables complements the flavors perfectly.

Make-Ahead Tips
Prepare components in stages for easy assembly:
- Make and brown meatballs up to 2 days ahead, storing in refrigerator. Simmer in sauce just before serving.
- Grate cheese and prepare toppings morning of serving.
- For longer storage, freeze cooked meatballs in sauce up to 3 months.
Temperature Considerations
Monitor broiler carefully - every oven is different. Keep assembled subs warm by tenting with foil, but don't wrap tightly or bread will become soggy. If making multiple batches, keep meatballs and sauce hot in covered pan over low heat.
