Step 1

Slice the loaf of bread in half horizontally and use your hands to hollow out each half by removing the soft bread inside. This will create cavities for the filling.

Step 2

Leave 1/2-inch of soft bread near the crust, taking care not to tear through the crust.

Step 3

Stir the salad once more to reincorporate the oil and seasonings, then spread about 2 cups total on the 2 pieces of bread. Use the back of a spoon to really smoosh it down into the bread, covering the entire surface.

Step 4

Layer the salami, capicola, mortadella, mozzarella, and provolone on the bottom piece of bread. Carefully flip the top piece of bread on top.

Step 5

Tightly wrap the muffuletta with foil and allow it to sit for at least 1 hour at room temperature for the flavors to marry and the oil to soak into the bread.

Step 6

Place the wrapped sandwich into the air fryer and heat at 300 degrees F, and cook until the cheese has melted, about 5-7 minutes.
