Below the bowls, a loaf of crusty bread is sliced thickly and arranged in a curved line with the crust showing a light dusting of flour.

This Pesto and Mozzarella Grilled Cheese Sandwich Recipe shines because of its straightforward, quality ingredients. Each one contributes something essential, from flavor and creaminess to that perfect crispy exterior, making the sandwich just right every time.

  • 4 slices sourdough bread: Choose a hearty loaf with a nice crust for the best texture and flavor contrast.
  • 4 tablespoons basil pesto: Fresh or store-bought works well; this herby spread gives the sandwich its vibrant, aromatic kick.
  • 3 tablespoons salted butter: Using salted butter adds extra flavor and helps achieve that golden, crispy crust you crave.
  • 4 slices fresh mozzarella cheese: Creamy and mild, fresh mozzarella melts beautifully and adds a luscious texture.

How to Make Pesto and Mozzarella Grilled Cheese Sandwich Recipe

Step 1: Spread the Pesto

Start by spooning a generous tablespoon of basil pesto onto the inside of each slice of sourdough bread. Use the back of your spoon to evenly spread it, making sure each bite will be bursting with those fresh, herbaceous flavors that define this sandwich.

Step 2: Add the Mozzarella

Thinly slice your fresh mozzarella if it’s not pre-sliced, or go all in with extra cheese if you like it gooey like I do. Layer 2 to 3 slices on top of the pesto-covered bread, depending on the size of your bread and how cheesy you want to get.

Step 3: Assemble the Sandwich

Place the second slice of pesto-spread bread on top of the mozzarella, pressing down gently to keep everything together and ready for cooking.

Step 4: Melt the Butter and Start Grilling

Heat 1½ tablespoons of salted butter in a skillet or griddle over medium-low heat. The low heat is key to melting the cheese thoroughly without burning the bread.

Step 5: Grill with a Lid

Once the butter is melted, place your sandwiches in the pan and cover with a lid. The trapped steam is a game-changer here, helping the cheese melt perfectly while the bread toasts evenly.

Step 6: Flip and Finish Grilling

When the bottom of your sandwich reaches your preferred golden brown, add the remaining 1½ tablespoons of butter and let it melt quickly. Carefully flip the sandwich over and grill the other side until equally golden and crispy.

Step 7: Slice and Serve Immediately

Take the sandwiches off the heat, cut them in half, and serve without delay to enjoy that ooey-gooey mozzarella goodness right when it’s best.

The sandwich has three layers: two outer layers of golden-brown toasted bread with a slightly crisp texture, and a thick middle layer of melted white cheese mixed with green herbs or pesto that peeks out slightly beyond the bread. In the background, there is a blurred white bowl with a spoon inside. The lighting emphasizes the warm toast and creamy cheese, creating a cozy and inviting feel.

Garnishes

To elevate your pesto and mozzarella grilled cheese sandwich, consider sprinkling freshly ground black pepper or a pinch of red pepper flakes to add a little kick. A few fresh basil leaves on top can also enhance the herbal brightness and add a pop of color that looks as amazing as it tastes.

Side Dishes

This sandwich pairs wonderfully with a fresh green salad dressed in a light vinaigrette to balance the richness. Tomato soup is a classic side that complements the cheesy, herby flavors beautifully, creating a nostalgic yet sophisticated meal.

Creative Ways to Present

For a fun twist, cut the sandwich into smaller finger-sized pieces for a party platter. You can also serve it open-faced with an extra drizzle of pesto on top or add a handful of arugula inside for a peppery crunch that livens up each bite.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers, wrap your Pesto and Mozzarella Grilled Cheese Sandwich tightly in foil or plastic wrap and store it in the fridge for up to two days. Keep in mind the bread may lose some crispness over time, but the flavors remain delightful.

Freezing

While this sandwich is best enjoyed fresh, you can freeze it before grilling. Wrap tightly and freeze for up to one month. When ready to eat, thaw in the fridge overnight and cook as usual for a quick, freshly grilled sandwich.

Reheating

To reheat, avoid the microwave to keep the crust crispy. Instead, reheat in a skillet over low heat until the cheese melts and the bread crisps back up nicely, just like when freshly made.

FAQs

Can I use other types of bread?

Absolutely! While sourdough adds great flavor and texture, rustic or artisan white bread also works well. Just make sure the bread is sturdy enough to hold all that cheesy goodness without getting soggy.

Is it possible to make this sandwich vegetarian?

This entire Pesto and Mozzarella Grilled Cheese Sandwich Recipe is naturally vegetarian, as all the ingredients come from plant or dairy sources, perfect for meat-free meals.

Can I substitute mozzarella with another cheese?

Yes! While fresh mozzarella gives a beautiful melt and mild flavor, you can use provolone, fontina, or even a good melting cheddar for a different taste profile.

How can I make this sandwich vegan?

To veganize this recipe, swap the butter for a plant-based spread and use dairy-free mozzarella-style cheese. Make sure your pesto is also free of cheese or anchovies for a fully vegan option.

What’s the best way to get perfectly melted cheese without burning the bread?

Cooking over medium-low heat and covering the pan with a lid helps trap steam to melt the cheese evenly while allowing the bread to toast slowly without burning.

Description

This Pesto and Mozzarella Grilled Cheese Sandwich is a quick and delicious twist on the classic grilled cheese. Featuring fresh mozzarella and fragrant basil pesto sandwiched between slices of sourdough bread, it’s a gooey, flavorful treat perfect for a comforting lunch or easy dinner.


Ingredients

Sandwich

  • 4 slices sourdough bread (Izzio brand recommended)
  • 4 tablespoons basil pesto (or your favorite pesto)
  • 4 slices fresh mozzarella cheese (or more to taste, thinly sliced)

For Cooking

  • 3 tablespoons salted butter (or more if needed)


Instructions

  1. Spread Pesto on Bread: Spoon 1 tablespoon of basil pesto onto the inside of each slice of sourdough bread. Use the back of the spoon to spread it thinly and evenly across the surface.
  2. Prepare Cheese: Thinly slice fresh mozzarella cheese if not using pre-sliced. Depending on the bread size, top one side of the pesto-spread bread with 2 to 3 slices for a rich cheesy layer.
  3. Assemble Sandwich: Place the second slice of pesto-spread bread on top, pesto side facing the cheese, to form the sandwich.
  4. Melt Butter: Heat 1½ tablespoons of salted butter in a skillet or griddle over medium-low heat until melted and lightly foaming.
  5. Cook Sandwiches: Place the sandwiches in the skillet and cover with a lid. This traps steam inside, helping the cheese melt more quickly and evenly.
  6. Flip and Butter: When the underside of the sandwich is golden brown to your liking, add the remaining 1½ tablespoons of butter. Once melted, carefully flip the sandwiches to cook the other side until golden and cheese is melted.
  7. Serve: Remove from skillet, cut sandwiches in half, and serve immediately while warm and gooey.

Notes

  • Use fresh mozzarella for a creamy, melty texture, but pre-sliced works well for more cheese.
  • Covering the pan helps melt cheese faster by trapping steam.
  • Adjust butter quantity as needed to achieve a golden, crispy crust without burning.
  • Sourdough bread adds a nice tang and crunch; other rustic breads work too.
  • Serve with tomato soup or salad for a complete meal.
