To make the perfect copycat Starbucks Grilled Cheese sandwich at home, follow these simple instructions.
Preheat a skillet or griddle over medium heat. If you have an air fryer, you can also use that to make this recipe.
In a small bowl, mix together butter and Parmesan cheese. Spread the butter mixture generously onto bread slices.
Place the bread slices butter-side down on the skillet or griddle. Add a slice of sharp white cheddar cheese and a sprinkle of shredded mozzarella cheese on each slice.
Top each slice of bread with another slice of bread, butter-side up.
Allow the sandwiches to cook for 3-4 minutes on each side, or until the bread is golden and toasty and the cheese is melted and gooey.
Once the sandwiches are done, remove them from the skillet or griddle and serve immediately.
