These Italian Sub Squares take your favorite sandwich fixings and turn them into a delicious, shareable dish that's perfect for big groups. Layered with tasty deli cuts, melty provolone, and tangy peppers all wrapped in puffy crescent dough, you'll get all the amazing Italian sub flavors in a handy, easy-to-grab form.
I found this recipe when planning a family get-together and now it's my number one pick for parties. There's something magical about how the crescent dough turns golden and fluffy while locking in all those yummy Italian flavors.
Key Ingredients Breakdown
- Crescent dough sheets: Makes assembly super easy
- Tasty deli meats: Go for sliced-to-order if you can
- Provolone cheese: Pick regular fat for better melt
- Roasted red peppers: The ones in jars work great
- Pepperoncini: Gives that nice zingy kick
- Homemade pesto: Tastier than store-bought

Simple Cooking Instructions
- Getting Started:
- Coat the pan well. Carefully open dough. Push into all edges. Make small edge rim. Look for any tears.
- Adding Everything:
- Put cheese down first. Mix up meat varieties. Spread peppers all around. Keep everything flat. Top with more cheese.
- Finishing Assembly:
- Lay dough on top gently. Press edges down firmly. Cut off extra bits. Brush egg mix on top. Spread pesto everywhere.
- Cooking It:
- Start with foil on top. Keep an eye on it. Take foil off carefully. Look at the sides. Don't let it burn.
- Getting Ready to Eat:
- Let it sit briefly. Cut into squares. Make it look nice. Enjoy while warm. Have napkins ready.

I came up with this idea because I love Italian subs but needed something easier to share at parties.
Smart Heat Control
I've made this so many times and learned that getting the temperature right really matters. Starting at 350°F with foil on top lets everything heat up without burning. Taking the foil off at the end gives you that beautiful golden top layer.
Prep-Ahead Tricks
You can totally make these squares ahead of time. I often put everything together up until the egg wash part, wrap it tight, and stick it in the fridge for up to a day. When you're ready to cook, just add the egg wash and cook it a bit longer, about 5-7 extra minutes.
Keeping Leftovers Fresh
They're best right after cooking, but any extras keep really well. I put them in a sealed container in the fridge for up to three days. When I want to eat them again, I pop them on a lined baking tray at 325°F for about 10 minutes to make the outside crispy again.
What Goes Well With It
These squares work great as part of an Italian food spread. I like to put them next to a crisp green salad, pickled veggies, or Italian pasta salad. At parties, sometimes I'll set up dips like marinara sauce and ranch dressing on the side.
Ways To Switch It Up
I've tried lots of different versions over time. Adding some fresh spinach gives you color and makes it healthier, while swapping in meats like capicola or mortadella brings real Italian deli taste. For extra kick, sometimes I throw in some sliced banana peppers.
Fixing Common Problems
If the dough sticks to your hands, just put a little flour on them when pressing it into the pan. If the top starts getting too brown too fast, just cover it loosely with foil until it's fully heated through.

These Italian Sub Squares have turned into my go-to party dish. That mix of flaky dough, tasty meats, and gooey cheese makes something really special that always gets people talking. Whether it's a backyard cookout or fancy dinner party, they're always a hit.
