Ingredients
- 4 slice sourdough bread (1/2-inch thick)
- 2 tbsp mayonnaise
- 2 tbsp unsalted butter
- 3 oz sharp cheddar (grated)
- 2 oz Gruyère (grated)
- 1 tsp Dijon mustard
- 1 pinch flaky salt
Instructions
- 1
Spread mayo thinly on one side of each slice. Spread Dijon on the other (inside) sides of two slices.
Mayo browns more evenly than butter and won't burn — diner secret.
- 2
Pile grated cheddar and Gruyère on the Dijon sides. Top with the other slices, mayo-side out.
Grated cheese melts faster and more evenly than slices.
- 3
Melt butter in a skillet over medium-low heat. Add sandwiches and cook 3-4 minutes until deep golden.
Medium-low is key. High heat = burnt bread, cold cheese.
- 4
Flip carefully, press gently with a spatula, and cook 3-4 more minutes until the second side is crisp and cheese is fully molten.
- 5
Rest 1 minute, cut on the diagonal, finish with flaky salt.

Nutrition

Tips
- •Use two cheeses: one for flavor (cheddar), one for melt (Gruyère/Fontina).
- •Cover the pan for the last minute to force-melt the interior.
- •Room-temp cheese melts faster. Grate and rest 10 minutes before cooking.
Substitutions
- Gruyère → Fontina or Havarti
- sourdough → Pullman loaf or country white
- mayo → softened butter (less crisp)
Leftovers
Best eaten immediately. If needed, reheat in a dry skillet over medium-low, 2 min per side.
