Step 1: Prepare the cheese

• Grate the cheddar and mozzarella cheese.

• Mix the cheeses together in a bowl.

• Add black pepper and garlic powder if desired.

• Keep the cheese ready for assembling.

Tip: Grated cheese melts more evenly than thick slices.

Step 2: Prepare the bread

• Take four slices of bread.

• Spread a thin, even layer of softened butter on one side of each slice.

• Make sure the edges are covered for an evenly golden crust.

Step 3: Assemble the sandwich

• Place two bread slices on a clean board with the buttered sides facing down.

• Add a generous layer of grated cheese on the unbuttered sides.

• Spread the cheese evenly, leaving a small border around the edges.

• Place the remaining bread slices on top, with the buttered sides facing outward.

You now have two assembled sandwiches.

Step 4: Heat the pan

• Place a non-stick pan over low to medium-low heat.

• Allow it to warm for about 1 minute.

• Avoid high heat because the bread may burn before the cheese melts.

Step 5: Cook the sandwich

• Place the sandwich in the heated pan.

• Cook for approximately 3–4 minutes.

• Press gently with a spatula to help the bread make even contact with the pan.

• Check the underside. It should become golden brown and crispy.

Step 6: Flip and cook the other side

• Carefully flip the sandwich using a spatula.

• Cook the other side for another 3–4 minutes.

• Reduce the heat if the bread is browning too quickly.

• Continue cooking until the cheese melts completely.

Step 7: Serve the sandwich

• Remove the sandwich from the pan.

• Let it rest for approximately 1 minute.

• Cut diagonally into two halves.

• Serve immediately while the cheese is hot and melted.
