Step 1

Oven method (great for a crowd of six or fewer): Put a rimmed baking sheet on the middle rack of the oven and preheat to 450 degrees F. Make one sandwich per person: Sandwich 2 slices of cheese between 2 slices of bread. Spread or brush the outside of the sandwich with 1 tablespoon of fat. Place on the preheated baking sheet and cook until the cheese starts to melt, about 5 minutes. Flip the sandwich and bake until golden brown, an additional 5 minutes.

Step 2

Panini press method (for crispy crunchy sandwich that needs minimal attention): Sandwich 2 slices of cheese between 2 slices of bread. Preheat a panini press to medium heat. Spread or brush the outside of the sandwich with 1 tablespoon of fat and place in the press. Close the top and cook until lightly browned and the cheese is melted, 5 to 6 minutes.

Step 3

Skillet method (fool-proof and low-tech): Sandwich 2 slices of cheese between 2 slices of bread. Preheat a skillet over medium-low heat. Spread or brush the outside of the sandwich with 1 tablespoon of fat and cook until lightly browned, 3 to 4 minutes. Flip the sandwich, and continue cooking until browned and the cheese is melted, 3 to 4 minutes more.
