This recipe calls for a handful of simple ingredients that each play a crucial role in building the perfect grilled cheese experience. From the fragrant pesto to the buttery crust, every component is essential to bring harmony in flavor, texture, and color.

2 slices sourdough bread: Offers a tangy and crunchy base that holds up beautifully to grilling.
2 tablespoons pesto: Adds fresh herbs and a vibrant green color, infusing each bite with bold flavor.

1 tablespoon butter: Creates a golden, crispy exterior that’s rich and satisfying.

How to Make Sourdough Pesto Grilled Cheese Recipe

Step 1: Prepare Your Ingredients

Start by gathering all your ingredients so everything is within reach. Slice your mozzarella thinly for easy melting, and spread the pesto evenly on one side of each sourdough slice. This ensures flavor is balanced in every bite.

Step 2: Assemble the Sandwich

Layer the sliced mozzarella on top of the pesto spread on one slice of bread. Then, place the second slice of bread on top with the pesto side facing inward. Press gently to help the sandwich hold together.

Step 3: Butter the Bread

Spread butter on the outside of both slices of bread. This will give you that beautifully crisp, golden crust as you cook your sandwich in the pan.

Step 4: Grill to Perfection

Heat a skillet over medium-low heat and place your sandwich in the pan. Cook slowly, turning once after about 3-4 minutes, until both sides are golden brown and the mozzarella is melted to gooey perfection. Patience here is key to allow the cheese to melt without burning the bread.

Garnishes

A sprinkle of freshly cracked black pepper or a few torn basil leaves on top adds a fresh, aromatic touch that complements the pesto beautifully. You can also drizzle a bit of balsamic glaze for a touch of sweetness and elegance.

Side Dishes

This grilled cheese pairs wonderfully with a simple tomato soup for a classic combo, or try it alongside a crisp green salad tossed in lemon vinaigrette to balance out the richness. Roasted vegetables also make a lovely accompaniment.

Creative Ways to Present

For a fun twist, cut your sandwich into bite-sized triangles and serve them on a platter with small bowls of extra pesto for dipping. They also make great finger food for gatherings and parties, guaranteed to impress.

Make Ahead and Storage

Storing Leftovers

You can wrap leftover sandwiches tightly in plastic wrap or foil and keep them in the refrigerator for up to two days. This helps maintain freshness and keeps the bread from drying out.

Freezing

To freeze, assemble the sandwich but do not cook it. Wrap it well in plastic wrap and then foil, and freeze for up to one month. When you’re ready, thaw in the fridge before grilling for best results.

Reheating

Reheat your grilled cheese in a skillet over low heat to maintain the crisp crust while warming the cheese inside. Avoid microwaving if possible, as it tends to make the bread soggy and the cheese rubbery.

FAQs

Can I use a different type of cheese?

Absolutely! While mozzarella melts beautifully in this recipe, feel free to experiment with provolone, fontina, or even a sharper cheddar to change the flavor profile.

Is pesto homemade necessary or can I use store-bought?

Store-bought pesto works perfectly well and saves time. Just choose a quality pesto with fresh herbs and olive oil for the best taste.

What if I don’t have sourdough bread?

While sourdough is ideal for its flavor and texture, you can substitute with any crusty bread you enjoy. Just make sure it’s hearty enough to hold the sandwich together without becoming soggy.

How can I make this recipe vegan?

Swap the mozzarella for vegan cheese and use a plant-based butter alternative to make a delicious vegan version of this Sourdough Pesto Grilled Cheese Recipe.

Definitely! Adding slices of tomato or fresh arugula can introduce bright flavors and a bit of freshness, making the sandwich even more exciting.
