Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Start by preparing all your ingredients so the cooking process is smooth. Slice the mozzarella into even pieces and chop the sun-dried tomatoes finely so they distribute well inside the sandwich.
Place two slices of sourdough bread in a cold frying pan. If your pan is large enough, you can prepare more sandwiches at the same time. Spread a thin layer of butter on one side of each slice of bread, then flip them so the buttered side is facing down.
Begin layering the sandwich by placing slices of mozzarella on each piece of bread. Add about one tablespoon of pesto on top of the cheese and spread it gently so it covers the surface. Sprinkle the chopped sun-dried tomatoes evenly over the pesto layer.
Add another layer of mozzarella to help hold the filling together and create a richer melt. Place a second slice of bread on top to close the sandwich. Press down lightly with your hand so the ingredients settle inside.
Spread a little butter on the outer top side of the bread. Turn the heat on to medium-low and allow the pan to warm gradually. Slow cooking is important to ensure the cheese melts fully without burning the bread.
Cook the sandwich for several minutes until the bottom becomes golden brown and crisp. Carefully flip it using a spatula, then cook the other side until it reaches the same golden color and the cheese is fully melted inside.
Remove the sandwich from the pan and let it rest for one to two minutes before cutting. This helps the cheese set slightly so it does not spill out too quickly when sliced. Serve warm for the best texture and flavor.

Variations
You can customize this sandwich in many ways. Try using different cheeses such as provolone, cheddar, or fontina for a stronger or milder flavor. You can also replace sourdough with rustic white bread or whole grain bread if preferred. For extra freshness, add spinach leaves or roasted vegetables like peppers or zucchini. If you want a spicier version, mix a small amount of chili flakes into the pesto.
Storage/Reheating
This sandwich is best enjoyed fresh, but you can store leftovers if needed. Wrap cooked sandwiches in foil or place them in an airtight container and refrigerate for up to 2 days. To reheat, warm them in a skillet over medium-low heat until the bread becomes crispy again and the cheese softens. Avoid microwaving, as it can make the bread soft and less enjoyable. You can also prepare the sandwiches ahead of time and store them un-cooked in the refrigerator for up to 24 hours before grilling.
