Step 1: Prepare the Ingredients

Start by preparing your ingredients. Slice your bread into two even slices per sandwich. If you’re using fresh mozzarella, slice it into rounds or shred it depending on your preference. For the best melt, make sure the mozzarella is fresh, as it’s more likely to get that perfect gooey consistency when grilled. You can also prep any additional toppings like tomato slices or basil leaves at this time.

Step 2: Butter the Bread

Take your butter (make sure it’s softened to room temperature) and spread a thin, even layer on one side of each slice of bread. The butter will give the bread that crispy, golden-brown texture when grilled. If you prefer, you can substitute olive oil for a slightly different flavor, or even use garlic butter to infuse the bread with a savory garlic flavor.

Step 3: Assemble the Sandwich

Now it’s time to assemble your sandwich. Lay one slice of bread, butter-side-down, on a clean surface. Place a generous amount of mozzarella cheese on the bread. Be sure to evenly cover the surface of the bread with cheese, allowing it to melt evenly as the sandwich grills.

If you’re adding tomatoes or basil, now’s the time to layer them on top of the cheese. These ingredients will provide a fresh, flavorful contrast to the rich cheese. Once you have your toppings in place, add the second slice of bread, butter-side-up.

Step 4: Grill the Sandwich

Heat a non-stick skillet or griddle over medium heat. Once it’s hot, place your assembled sandwich onto the skillet, buttered side down. If you want to enhance the crispiness of the bread, you can lightly drizzle some olive oil on the skillet or add a little more butter.

Cook the sandwich for about 2-3 minutes, or until the bread is golden brown and crispy. Flip the sandwich over carefully with a spatula, pressing down slightly to ensure even grilling. Cook for another 2-3 minutes on the other side, until the cheese is melted and the bread is evenly toasted.

Step 5: Serve

Once your Grilled Mozzarella Sandwich is golden and crispy, remove it from the skillet and let it rest for a minute before cutting. Slice the sandwich diagonally, revealing the melty cheese inside. The mozzarella should pull away in gooey strings, showcasing the perfect balance of crispy bread and soft cheese. If you’re using balsamic glaze, drizzle it over the top for an extra touch of flavor.

Serve your sandwich immediately while it’s still hot and melty. For the perfect pairing, consider serving it with a side of tomato soup, salad, or crispy fries.
