Spread softened butter on one side of each bread slice. Sprinkle Italian seasoning over the buttered sides if desired.
Place 4 slices of bread, butter-side down, on a clean surface. Layer each with 1 slice of mozzarella, 6–8 slices of pepperoni, a spoonful of pizza sauce, and another slice of mozzarella.
Top with the remaining bread slices, butter-side up, to close the sandwiches.
Heat a large skillet or griddle over medium heat. Cook sandwiches until golden and crisp on both sides, about 3–4 minutes per side, pressing lightly with a spatula.
Remove from heat, slice in half, and serve warm with extra pizza sauce for dipping.
Variations
Supreme Style: Add sautéed onions, peppers, or mushrooms inside the sandwich.
Meat Lovers: Include slices of cooked sausage or Canadian bacon along with the pepperoni.
Veggie Delight: Skip the meat and add spinach, olives, or roasted vegetables.
Spicy Kick: Use pepper jack cheese or add crushed red pepper flakes inside.
Tips
Use thick, sturdy bread like sourdough to hold the filling without getting soggy.
Shredded mozzarella melts more evenly than slices, but either works well.
To make the bread extra flavorful, brush the tops with garlic butter before grilling.
Serve immediately for the best melty texture—these sandwiches are at their peak when hot.
