Step 1: Make the Butter Mixture
In a small bowl, combine melted butter, Parmesan, garlic powder, and oregano. Mix well.
Tip: For a crispier texture, lightly toast the bread for a couple of minutes before adding the butter. For a softer center, skip this step.
Step 2: Prepare the Bread
Place the bread slices in a single layer on a baking sheet or in an air fryer basket. Spread the garlic butter evenly over each slice.
Step 3: Add the Cheese
Sprinkle mozzarella evenly over each slice, then top with a slice of provolone.
Tip: Placing provolone on top helps everything melt smoothly and keeps the shredded cheese in place.
Step 4: Cook
- Air fryer: 350°F for about 5 minutes
- Oven: 375°F for 6–7 minutes
Cook until the cheese is fully melted and lightly golden on top.
Step 5: Serve
Garnish with parsley if desired and serve hot while the cheese is perfectly melted and stretchy.
