How to Make Pesto Butter Grilled Cheese Sandwiches Recipe

Step 1: Prepare the Pesto Butter

Start by combining 1 tablespoon of basil pesto with your softened unsalted butter in a small bowl. Mixing them well ensures each slice of bread gets a beautifully even coating, which will deliver that incredible herby crunch once grilled.

Step 2: Butter Your Bread

Spread the pesto butter generously on one side of each slice of bread. This buttery layer is what crisps up in the pan, creating the golden exterior that is essential for any great grilled cheese.

Step 3: Layer with Pesto and Cheese

Flip each bread slice so the buttered side faces down, then spread an extra layer of plain pesto on the unbuttered sides. Top two of the bread slices with your chosen cheese, stacking the slices evenly to allow the cheese to melt perfectly.

Step 4: Assemble and Cook

Sandwich the slices so the buttered sides are facing outwards. Heat a skillet over medium heat and place the sandwiches down. Cook until the bottom is golden brown and crispy, then carefully flip and cook the other side. Patience here ensures the cheese melts beautifully and the bread crisps evenly.

Step 5: Rest and Serve

Once perfectly browned and melty, transfer your sandwiches to a cutting board and let them rest for about 3 minutes. This resting time lets the cheese settle just enough to keep things gooey but not messy when you slice.

Each sandwich has three visible layers: the top and bottom layers are golden brown toasted bread with a slightly crispy texture, while the middle layers are filled with a creamy mixture containing white cheese, green herbs, and small pieces of tomato.

Garnishes

Adding a few simple garnishes can elevate your Pesto Butter Grilled Cheese Sandwiches Recipe even more. A light sprinkle of freshly grated Parmesan, chopped fresh basil, or a dash of cracked black pepper brings fresh color and a burst of flavor that complements the sandwich perfectly.

Side Dishes

Pairing your grilled cheese with the right sides turns this meal into a magnificent spread. Consider a fresh, crisp green salad with lemon vinaigrette to cut through the richness, or a cup of homemade tomato soup, which is a timeless partner to any grilled cheese delight.

Creative Ways to Present

For a delightful presentation, cut the sandwiches into fun shapes using cookie cutters, or serve them open-faced topped with tomato slices and a drizzle of balsamic glaze. You can also stack mini sandwiches as sliders for a party platter that will wow guests with both flavor and charm.

Make Ahead and Storage

Storing Leftovers

Leftover Pesto Butter Grilled Cheese Sandwiches Recipe can be stored wrapped tightly in plastic wrap or foil and refrigerated for up to 2 days. Keeping them tightly sealed helps maintain freshness and prevents the bread from drying out too quickly.

Freezing

If you want to preserve these sandwiches for longer, freeze them individually wrapped in plastic and then foil. They freeze well for up to one month. When you’re ready to enjoy, let them thaw in the fridge overnight before reheating.

Reheating

The best way to reheat these grilled cheese sandwiches is on a skillet over medium-low heat. This method revives the crispy exterior while gently melting the cheese again. Avoid using the microwave as it tends to make the bread soggy and the cheese rubbery.

FAQs

Can I use fresh pesto instead of store-bought?

Absolutely! Fresh pesto works wonderfully and can add an even brighter, more vibrant basil flavor to your sandwiches. Just remember to mix it well with the butter and spread it evenly.

What types of cheese work best in this recipe?

Gouda, Muenster, and Monterey Jack are fantastic because they melt beautifully and have mild, creamy flavors that complement the pesto. You can experiment with other melting cheeses like Fontina or Havarti too.

Can I make this sandwich vegan or dairy-free?

Yes! Substitute the butter with a plant-based alternative and use vegan cheese slices that melt well. The pesto must also be checked or made without cheese to keep it vegan.

Is sourdough really necessary?

Sourdough is preferred because its texture holds up nicely to the butter and grilling process while adding a tasty tang. But you can use other thick-cut breads like ciabatta or rustic white bread if you prefer.

How do I avoid soggy bread when making this sandwich?

The key is spreading butter on the outside and grilling on medium heat to get a crisp crust without burning. Also, avoid overloading with cheese or wet ingredients that could make the bread soggy.
