Ingredients:

  • 4 tbsp unsalted butter, softened
  • 1 tbsp mayonnaise
  • 2 cloves garlic, finely minced
  • 1 tbsp fresh parsley, finely chopped
  • 2 tbsp Parmesan cheese, freshly grated
  • 0.25 tsp kosher salt
  • 4 thick slices sourdough bread
  • 1 cup sharp cheddar cheese, freshly shredded
  • 1 cup mozzarella cheese, freshly shredded

Instructions:

  1. Mix 4 tbsp softened butter, 1 tbsp mayo, 2 minced garlic cloves, 1 tbsp parsley, 2 tbsp Parmesan, and 0.25 tsp salt in a small bowl.
  2. Combine the cheeses. Toss 1 cup sharp cheddar and 1 cup mozzarella together in a bowl. Note: This ensures an even distribution of flavor and melt in every bite.
  3. Spread the garlic butter mixture generously on one side of each of the 4 sourdough slices.
  4. Place your skillet over medium low heat and let it warm up for 2 full minutes.
  5. Place two slices of bread, butter side down, into the warm pan. You should hear a gentle sizzle.
  6. Add the filling. Divide the cheese mixture evenly between the two slices in the pan.
  7. Top with the remaining bread slices, making sure the garlic butter side is facing up.
  8. Press gently. Use your spatula to lightly press down, encouraging the cheese to make contact with the bread.
  9. Cook for about 3-4 minutes until the bottom is deep mahogany and the crust is lacy.
  10. Flip and cook for another 3 minutes until the cheese is completely molten and the bread shatters when tapped.
