The Secret Ingredient for the Perfect Grilled Cheese Sandwich

The Secret Ingredient for the Perfect Grilled Cheese Sandwich

Mayonnaise spread on the outside of the bread produces a crisp, evenly browned crust while the cheese melts into a rich, savory center. This recipe makes two sandwiches in about 11–13 minutes.

Ingredients
  

Sandwiches
  • 4 slices Sandwich bread, sourdough, white, or country-style
  • 4 ounces Sliced or grated cheese
  • 2 tablespoons Mayonnaise
Optional
  • 1 teaspoon Dijon mustard

Method
 

Step-by-Step
  1. Spread mayonnaise evenly over one side of each bread slice, making sure to reach the edges without applying a thick layer.
  2. Turn two slices over so the uncoated sides face up. Layer the cheese over those sides, add the Dijon mustard if using, and top with the remaining bread slices so the mayonnaise-coated sides face outward.
  3. Heat a skillet or griddle over medium-low to medium heat. Avoid high heat because the bread can brown before the cheese has time to melt.
  4. Place the sandwiches in the pan and cook for about 3–4 minutes per side, pressing lightly with a spatula, until the bread is golden brown and crisp.
  5. Turn the sandwiches once and cook the second side until browned and the cheese is fully melted. If the bread colors too quickly, reduce the heat and cover the pan briefly.
  6. Rest the sandwiches for 1 minute, then slice and serve while the centers are warm and molten.

Notes

Grated cheese melts more quickly and evenly than thick slices. For a butter-based variation, use about 2 tablespoons softened unsalted butter in place of the mayonnaise.
