Method
- Prepare the sandwich: Place the bread slices on a cutting board. Spread the top side of each slice with mayonnaise. Flip one slice of bread and spread its other side with Dijon mustard. Layer the cheddar and Gruyère or Raclette cheeses on top of the mustard. Place the other slice of bread on top of the cheese, mayonnaise side out.
- Cook the sandwich: Heat a nonstick or cast-iron skillet over medium-low heat. Melt enough butter in the pan to coat it. Place the sandwich in the pan, cover, and cook for 2 to 3 minutes, or until the bottom slice of bread is golden brown and crisp.
- Flip the sandwich, replace the lid, and cook until the other slice of bread is golden brown and the cheese is melted, 1 to 3 minutes. Reduce the heat to low if the bread is getting too brown before the cheese is fully melted.
- Slice and serve immediately.
Notes
For make-ahead tips, you can assemble the sandwiches ahead of time and refrigerate them. When ready to cook, add them directly to the buttered pan. You can also pre-shred your cheeses and store them in an airtight container in the refrigerator for quicker assembly.
