This simple grilled cheese in the oven method makes six classic grilled cheese sandwiches per half sheet pan! BAKED grilled cheese? YES — hot and fresh, in just about 10 minutes... SO EASY!!!
Adjust oven rack to middle position and heat oven to 400℉.
Butter one side of 6 slices of bread and place each butter-side down on a sheet pan. Layer 1-2 slices of cheese on each slice of bread. Spread butter on 6 remaining slices of bread and place them buttered-side up on top of the cheese.
Bake for 5-6 minutes. Flip the sandwiches over and bake for an additional 5-6 minutes, until golden brown. Baking time may vary slightly depending on whether white or wheat bread is used.
