Ingredient Substitution Guide

1. Step 1

   Microwave the butter in a small, microwave-safe bowl until partially melted, 10 to 15 seconds. (Alternatively, melt 2 tablespoons of butter in the nonstick skillet you will cook the sandwiches in over medium heat. Pour the melted butter over the remaining 2 tablespoons butter in a small, heatproof bowl.) Add the Parmesan, parsley and grated garlic and stir to combine. The mixture should be spreadable, not liquid.  

2. Step 2

   Spread an even layer of the garlic butter over both sides of 2 slices of bread (about ½ tablespoon per side).Place the slices in a large nonstick skillet and top them with an even layer of mozzarella (⅓ cup each). Butter both sides of the remaining 2 slices of bread and place those on  top of the mozzarella to create 2 sandwiches. 

3. Step 3

   Place the skillet over medium-low heat and cook until the mozzarella is mostly melted and the underside is deep golden, 3 to 4 minutes. Flip the sandwiches and continue to cook until the other side is deep golden and the cheese completely melted, 2 to 3 minutes more. Cut in half (if desired) and serve immediately.

Tip

• The salted butter can be substituted for 4 tablespoons unsalted butter plus ⅛ teaspoon kosher salt (such as Diamond Crystal).
