Ingredients
- Sourdough or sturdy bread: Brings crunch and structure Look for slices with deep grain flavor
- Basil pesto: Fresh or store bought makes all the difference High quality olive oil and lots of basil give the best pesto punch
- Mozzarella cheese: Choose fresh mozzarella for creaminess or shredded for even melt Look for whole milk mozzarella for flavor
- Unsalted butter: Soft butter ensures an ultra crisp and flavorful crust on the bread
- Parmesan cheese: Optional but amps up the savory factor Use a wedge and grate it yourself for peak freshness
Instructions
- Prepare the Bread:
- Spread one tablespoon of pesto on one side of each bread slice Take your time to coat right to the edges so every bite has pesto flavor
- Assemble the Sandwiches:
- On two of the bread slices pesto side up pile on about three quarters cup of shredded mozzarella or use two slices of fresh mozzarella If you want extra flavor sprinkle a tablespoon of grated Parmesan on each Add the last two bread slices pesto side down pressing lightly to make a neat stack
- Butter the Outside of the Bread:
- Using a small spatula or knife coat the outer side of each sandwich with softened unsalted butter A thin even layer creates the best golden crust when toasted
- Grill the Sandwiches:
- Heat a nonstick skillet or griddle over medium heat Place the sandwiches in the pan Press gently with a spatula Cook for two to three minutes per side Adjust heat as needed so the bread turns deeply golden brown and the cheese melts fully
- Serve:
- Transfer to a cutting board Slice in half while hot Serve immediately for the full gooey cheese experience

Of all the ingredients basil pesto is my favorite The color and aroma fill my kitchen and my youngest daughter dances around the table when she spots that jar
Storage Tips
Wrap leftovers in foil and store in the fridge Reheat in a toaster oven to bring the bread back to its original crispiness Never microwave or the mozzarella can get rubbery I have had this sandwich taste almost as good the next day
Ingredient Substitutions

Success Stories
A friend made these for her book club using store pesto Everyone asked for the recipe and now it is their monthly potluck tradition My neighbor adds a layer of prosciutto for extra savoriness and swears it is her go to fast dinner
Freezer Meal Conversion
