🛒 Ingredients:

  • 1 large sub sandwich roll or small baguette, split lengthwise (about 12–16 inches)
  • 2 cups shredded mozzarella cheese
  • 1 cup shredded sharp cheddar cheese
  • 20–25 slices pepperoni
  • 1–2 fresh jalapeños, thinly sliced (remove seeds for less heat)
  • 2 tbsp butter, softened
  • 1 tbsp mayonnaise (optional, for extra crispiness)
  • ½ tsp garlic powder
  • ½ tsp Italian seasoning (optional)
  • Fresh parsley or basil for garnish (optional)

🔥 Directions:

1. Prep the Bread

  • Slice your sub roll lengthwise, but don’t cut all the way through — you want it hinged like a book.
  • Lightly butter both cut sides, and spread a thin layer of mayo if using (seriously ups the golden crunch).

2. Build the Layers

  • Sprinkle a thick layer of mozzarella and cheddar on the bottom half of the bread.
  • Layer the pepperoni slices generously over the cheese.
  • Add sliced jalapeños evenly across the top.
  • Top it all with another thick layer of cheese — more is more here!

3. Season It Up

  • Sprinkle garlic powder and Italian seasoning over the cheese for an extra flavor bomb.

4. Grill to Perfection

  • Heat a large skillet or griddle over medium-low heat.
  • Carefully transfer your loaded sub to the pan.
    (If it’s tricky to handle, you can use a spatula to help press it gently.)
  • Grill slowly, pressing down gently with a spatula, until the bottom is golden and the cheese starts melting, about 4–5 minutes.
  • Carefully flip (use two spatulas if needed!) and grill the other side until golden and gooey.

Pro Tip: You can cover the skillet loosely with foil or a lid to help the cheese melt faster without burning the bread.

5. Serve It Up

  • Let it cool for 1–2 minutes (if you can wait).
  • Slice into chunky pieces and sprinkle with fresh parsley or basil if you’re feeling fancy.

Customize Your Giant Grilled Cheese Sub
