This recipe was inspired by my love for Italian subs and the need to serve them efficiently at parties.
Temperature Management
Through many preparations, I've learned that proper temperature control is crucial. Starting at 350°F and covering with foil allows the layers to heat evenly without burning the top. Removing the foil for the final baking creates that perfect golden-brown crust.
Make-Ahead Strategy
These squares are perfect for advance preparation. I often assemble everything up to the egg wash stage, cover tightly, and refrigerate for up to 24 hours. When ready to bake, I add the egg wash and adjust baking time by adding 5-7 minutes.
Storage Solutions
While best enjoyed warm, leftovers keep beautifully. I store them in an airtight container in the refrigerator for up to three days. For reheating, I place them on a lined baking sheet at 325°F for about 10 minutes to restore the crispy crust.
Serving Suggestions
These squares shine as part of an Italian-themed spread. I serve them alongside a fresh green salad, marinated vegetables, or Italian pasta salad. For parties, I sometimes create a dipping station with marinara sauce and ranch dressing.
Customization Options
Over time, I've experimented with different variations. Adding a layer of fresh spinach creates color and nutrition, while substituting capicola or mortadella brings authentic Italian deli flavors. For extra zip, I sometimes add sliced banana peppers.
Troubleshooting Tips
If the dough seems sticky, dust your hands with flour while pressing it into the pan. If the top browns too quickly, tent with foil until fully heated through.
