Ultimate Crispy Cheddar-Gruyère Grilled Cheese

This grilled cheese sandwich is elevated with a foolproof technique and a blend of two cheeses for maximum flavor and crispiness.

There's nothing quite like a classic grilled cheese, but this version takes it to the next level. The secret lies in using a thin layer of mayonnaise on the outside of the bread, which creates an incredibly crispy, golden crust when cooked.

With a mix of sharp cheddar and nutty Gruyère, every bite is gooey, flavorful, and satisfying. Follow these simple steps, and you'll have the perfect grilled cheese every time.

Method

  1. Using a butter knife, spread a thin layer of the mayonnaise or softened butter on one side of each bread slice, ensuring full coverage up to the edges. Before spreading, make sure the slices are the same size and aligned so that when assembled, the shapes of the bread match up perfectly.
  2. Assemble the sandwich in the pan: Preheat a non-stick skillet or cast iron pan over medium heat. Once heated, place one slice of bread in the skillet, mayo/butter side down. Then, layer the 2 slices of cheddar cheese onto the bread, ensuring even coverage (depending on the shape of the bread, you may need to tear the cheese for even coverage). Evenly sprinkle the shredded Gruyère over the cheddar. Place the second slice of bread on top, mayo/butter side up.
  3. Cook the sandwich for 3 to 4 minutes on one side, or until it's golden brown and crispy. Using a spatula, carefully flip the sandwich over and cook the other side for another few minutes, or until it's also golden brown and the cheese inside has melted.
  4. Remove the grilled cheese from the skillet and place it onto a cutting board. Let it sit for a minute, then cut the sandwich in half using a sharp knife. Serve immediately while it's still warm.

💡 Tips

  • For extra crispiness, use mayonnaise instead of butter on the outside of the bread.
  • If your bread slices have holes, the cheese may leak out; choose a tight-crumbed bread for best results.
  • Let the sandwich rest for a minute before cutting to allow the cheese to set slightly, preventing it from oozing out completely.
