If you don't already have pesto in your pantry, you can find it in the pasta sauce aisle of most supermarkets.

Ingredients for Pesto Grilled Cheese Sandwich
Sourdough bread: A tangy and sturdy bread that holds up well to grilling and pairs perfectly with the flavors of pesto and cheese.
Pesto: A flavorful sauce made from basil, garlic, pine nuts, Parmesan cheese, and olive oil, adding a rich and nutty taste to the sandwich.
Mozzarella: A mild and creamy cheese that melts beautifully, creating a gooey and delicious filling.
Cheddar cheese: An alternative to mozzarella, offering a sharper flavor and equally good melting properties.
Butter: Softened butter is spread on the outside of the bread slices to ensure a golden, crispy crust when grilled.
Technique Tip for This Recipe
To achieve a perfectly golden and crispy grilled cheese sandwich, make sure to use softened butter and spread it evenly on the bread slices. This ensures even browning and prevents burning. Additionally, using a skillet with a lid can help melt the cheese more quickly and evenly by trapping the heat inside.

How To Store or Freeze This Recipe
Allow the sandwiches to cool completely before storing. This prevents condensation, which can make the bread soggy.
Wrap each sandwich individually in aluminum foil or parchment paper. This helps maintain the integrity of the bread and keeps the pesto and cheese from leaking out.
Place the wrapped sandwiches in an airtight container or a resealable plastic bag. This will help keep them fresh and prevent any unwanted odors from seeping in.
Store the sandwiches in the refrigerator if you plan to eat them within 2-3 days. For longer storage, place them in the freezer.
To freeze, lay the wrapped sandwiches flat on a baking sheet and place them in the freezer for about 1-2 hours. This initial freezing step helps them keep their shape.
Once frozen, transfer the sandwiches to a freezer-safe bag or container. Label with the date to keep track of freshness.
When ready to eat, thaw the sandwiches in the refrigerator overnight if frozen. For a quicker option, you can use the microwave on a low setting for a few minutes.
Reheat the sandwiches in a skillet over medium heat, or use a toaster oven or oven preheated to 350°F (175°C) until the bread is crispy and the cheese is melted, about 5-7 minutes.
For an extra crispy texture, you can reheat the sandwiches in a panini press or grill for a few minutes.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap the pesto grilled cheese sandwich in aluminum foil to prevent it from drying out. Place it on a baking sheet and heat for about 10-15 minutes, or until the cheese is melted and the bread is crispy.
Use a skillet on medium heat. Place the sandwich in the skillet and cover it with a lid to help the cheese melt evenly. Heat for about 2-3 minutes on each side, or until the bread is golden brown and the cheese is gooey.
For a quick method, use a toaster oven. Set it to 350°F (175°C) and place the sandwich directly on the rack. Heat for about 5-7 minutes, or until the cheese is melted and the bread is crispy.
If you’re in a hurry, use a microwave. Place the sandwich on a microwave-safe plate and cover it with a damp paper towel to keep it from drying out. Microwave on medium power for about 30-45 seconds, or until the cheese is melted. Note that this method may not keep the bread as crispy.
For an air fryer, preheat it to 350°F (175°C). Place the sandwich in the basket and heat for about 3-5 minutes, or until the cheese is melted and the bread is crispy.
