Packed with tasty deli meats, gooey provolone, and tangy peppers all tucked inside flaky crescent dough, you'll get all those Italian sandwich flavors in an easy-to-share dish.
I tried this at a family get-together and now I can't stop making it for parties. There's something magical about that golden, flaky dough wrapped around all those Italian goodies that folks just can't resist.

I came up with this after wanting to enjoy Italian subs at parties without the mess.
Getting The Heat Just Right
I've made this loads of times and getting the temperature right makes all the difference. Starting at 350°F with foil on top helps everything warm up without burning. Taking that foil off near the end gives you that beautiful golden top everyone loves.
Prep It Early
You can totally get this ready ahead of time. I often put the whole thing together right up to before the egg wash, wrap it tight, and stick it in the fridge for a day. When you're ready to cook, just brush on that egg and add a few extra minutes to the baking time.
Keeping Leftovers Fresh
They taste best warm from the oven, but leftovers are still really good. I pop them in a sealed container in the fridge where they'll stay nice for about three days. To warm them back up, I put them on a baking sheet at 325°F for around 10 minutes to get that crispiness back.
What To Serve With It
These squares go great as part of an Italian-style spread. I like to have them next to a simple green salad, some pickled veggies, or an Italian pasta salad. At parties, sometimes I'll set out little bowls of marinara and ranch for dipping.
Ways To Switch It Up
I've played around with different versions over time. Adding some fresh spinach gives nice color and some healthy stuff too, while swapping in meats like capicola or mortadella brings in true Italian deli taste. For extra kick, sometimes I throw in some sliced banana peppers.
Fixing Common Problems
If your dough feels too sticky, just dust your fingers with a bit of flour when pressing it into the pan. If the top starts getting too brown too fast, just lay some foil over it until it's heated all the way through.

These Italian Sub Squares have become my go-to party food. Something about that crispy crust with savory meats and melted cheese just works so well together and always gets folks talking. No matter if it's a backyard hangout or fancy dinner party, they're always a hit.
