12 slice(s) (3/4 inch thick) challah or brioche
6 tablespoon(s) butter, softened
12 ounce(s) shredded cheese, such as cheddar, jack, Fontina, Gouda,
mozzarella, or Gruyère (3 cups)
Optional additional toppings:
1. Grilled onions and bacon
Grainy mustard and sliced tomato
Smoked ham and roasted peppers
2. Butter one side of each slice of bread.
3. Heat a flat griddle or large frying pan over medium heat. Mound about 1/2 cup (2 ounces) cheese on each of 6 slices of bread (unbuttered side). Add any optional toppings (if using). Place remaining bread on top, buttered side up. Place 1 or 2 sandwiches (do not crowd) on griddle or skillet. (Don’t let griddle get too hot or bread will brown before cheese is melted.) When bread is golden brown underneath, turn sandwiches over and press flat with a spatula. Reduce heat to medium-low and continue cooking until cheese is melted and bread is golden brown on both sides. Repeat with remaining bread and cheese. Slice and serve hot.
