Method
- On a cutting board, spread mayonnaise on one side of each bread slice. Flip one slice and spread its other side with Dijon mustard.
- Layer the cheddar and Gruyère or Raclette cheeses on top of the mustard. Place the other bread slice on top, mayonnaise side out.
- Heat a nonstick or cast-iron skillet over medium-low heat. Melt enough butter in the pan to coat the bottom.
- Place the sandwich in the pan, cover, and cook for 2 to 3 minutes, until the bottom slice of bread is golden brown and crisp.
- Flip the sandwich, replace the lid, and cook for another 1 to 3 minutes, until the other slice of bread is golden brown and the cheese is melted. Reduce heat to low if bread browns too quickly.
- Slice and serve.
Notes
For make-ahead preparation, assemble the sandwiches without buttering the bread. Wrap each sandwich tightly in plastic wrap and refrigerate for up to 24 hours. When ready to cook, melt butter in the skillet and cook as directed, adding a few extra minutes if needed.
