½ cup
shredded extra-sharp cheddar cheese (2 ounces)
½ cup

2 tablespoons
unsalted butter

Gather Equipment

Cutting board
12-inch nonstick skillet
Spatula
Ruler
1
 
4 slices
hearty white or wheat sandwich bread
½ cup
shredded extra-sharp cheddar cheese (2 ounces)
½ cup
shredded mozzarella cheese (2 ounces)

Place bread slices on cutting board. Sprinkle cheddar evenly over 1 slice of bread. Sprinkle mozzarella evenly over second slice of bread. Place 1 bread slice on top of each sandwich and press down gently.

 
2
 
2 tablespoons
unsalted butter

In 12-inch nonstick skillet, melt butter over medium-low heat, swirling to evenly coat skillet, about 1 minute.

Place sandwiches in skillet and press down on them lightly with spatula. Cook sandwiches until first side is golden brown, 3 to 5 minutes.

Use spatula to flip sandwiches and press lightly again. Cook until second side is golden brown and cheese is melted, about 2 minutes.

Flipping Grilled Cheese Sandwich

Slide spatula completely underneath sandwich. Make sure spatula is large enough to hold sandwich.

Carefully place fingertips on top of sandwich. Lift spatula and flip sandwich over, moving your fingers out of the way as you flip sandwich onto second side. Repeat with remaining sandwich.

Turn off heat. Use spatula to transfer sandwiches back to cutting board. Let cool for 2 minutes.

While sandwiches cool, make a prediction: Which cheese do you think will stretch more when you pull apart your sandwiches: cheddar or mozzarella?

Use your hands to gently break cheddar sandwich in half. Hold left half of sandwich still in your left hand. Use your right hand to gently pull other half of sandwich to the right. Stop pulling once cheese breaks and is no longer connecting 2 halves of sandwich.
