Step‑by‑Step Instructions for Sourdough Pesto Grilled Cheese
Step 1: Prep Your Ingredients
Begin by gathering your ingredients: thick slices of sourdough bread, dry mozzarella cheese, basil pesto, and optional sun-dried tomatoes or cooked bacon. Ensure your cheese is patted dry to avoid a soggy sandwich. Spread a thin layer of butter on one side of each slice of sourdough for that perfect golden crisp.
Step 2: Assemble the Sandwich
In a cold frying pan, lay down the bread slices butter side down. On the unbuttered side of one slice, generously layer mozzarella cheese, followed by a tablespoon of basil pesto, and add sun-dried tomatoes or bacon if desired. Top with another layer of mozzarella, then place the second slice of sourdough on top, butter side up to create your Sourdough Pesto Grilled Cheese.
Step 3: Grill Your Sandwich
Heat your frying pan over medium heat. Once hot, gently place your sandwich into the pan. Grill for about 3-4 minutes or until the bottom slice is golden brown and the cheese starts melting. Use a spatula to press down lightly for even melting and to help the filling stay contained.
Step 4: Flip and Finish Cooking
Carefully flip your Sourdough Pesto Grilled Cheese sandwich onto the other side, now grilling the top for an additional 3-4 minutes. Look for a deep golden color on both sides, and ensure the cheese is fully melted. Adjust the heat as needed to avoid burning the bread while ensuring the cheese melts deliciously.
Step 5: Serve and Enjoy
Once cooked to perfection, remove the grilled cheese from the pan and let it cool for a minute. This brief resting period allows the cheese to set slightly. Slice the sandwich in half to reveal the gooey interior and serve immediately with your favorite side, like tomato soup, for an unforgettable meal!
