This grilled cheese with pesto and mozzarella delivers gooey cheese and herbaceous notes tucked inside buttery toasted bread. It is my trusty pick for cozy lunches or when dinner needs to happen in a flash. The combination reminds me of lively café lunches and lazy Sundays with family.
The first time I tried this twist on grilled cheese I fell for the way fresh pesto brightens the rich mozzarella. Now it is requested whenever my family wants something quick and indulgent.
Ingredients
- Sourdough or country-style bread: Four slices provide structure and flavor For best crunch seek out a loaf with a hearty crust and chewy crumb
- Fresh mozzarella: About 120 grams sliced This cheese melts beautifully giving the sandwich a stretchy pull For best results use mozzarella packed in brine and pat dry before slicing
- Basil pesto: Two tablespoons homemade or good-quality store bought add a punch of herbs and garlic If buying look for vibrant green pesto with visible basil bits and a fragrant fresh aroma
- Unsalted butter: Two tablespoons softened for spreading Butter on the outside creates that signature crunch and golden color Choose high-fat European-style butter for the most flavor
Instructions
- Prepare the Bread:
- Spread half a tablespoon of softened butter on one side of each bread slice making sure to reach the edges so every bite crisps
- Build the Sandwich Base:
- Place two bread slices buttered side down on your clean cutting board Keep the butter side facing the board
- Add the Pesto:
- Generously spread one tablespoon of pesto onto the unbuttered side of each base slice spreading evenly so every mouthful gets some basil flavor
- Layer with Mozzarella:
- Arrange the sliced mozzarella over the pesto in a single layer Try not to let it hang over the edges to minimize mess
- Top and Butter:
- Close each sandwich with the remaining bread slices buttered side facing out toward you so it will hit the skillet and toast up golden
- Get Cooking:
- Heat a non-stick skillet over medium heat so the butter sizzles not smokes Place both sandwiches in the pan Cook the first side for three to four minutes until deep golden brown and crisp
- Flip and Finish:
- Carefully flip using a wide spatula Press down gently to ensure good contact Cook another three to four minutes so the second side browns and the cheese melts through If needed lower the heat so the bread does not burn
- Rest and Slice:
- Transfer sandwiches to a board and rest for a minute before slicing This allows the cheese to set a bit for cleaner cuts
- Serve Hot:
- Slice each sandwich in half Serve while the mozzarella is stretchy and the pesto aroma is at its peak

Mozzarella is the heart of this sandwich I love how it stretches in long oozy threads when the grilled cheese is just cooked and still piping hot My kids always compete for the cheese pull and those golden extra crispy edges
