Sourdough Pesto Grilled Cheese Ingredients

For the Sandwich
• Sourdough Bread – The sturdy base for your grilled cheese; opt for a thick-cut version to avoid sogginess.
• Mozzarella Cheese – This is the star ingredient; using fresh mozzarella ensures a melty, gooey filling.
• Basil Pesto – A flavor enhancer that adds a burst of herby goodness; be careful not to use too much to prevent sogginess.
• Sun-Dried Tomatoes (optional) – Adds a tangy contrast; swap with fresh tomatoes if you desire a different texture.
• Cooked Bacon (optional) – Infuses savory depth; for a vegetarian option, replace it with sautéed mushrooms.
• Butter – Essential for grilling; a generous layer guarantees a crispy, golden crust.

Cooking Tips
• Heat Control – For the best melting cheese, cook on medium-low; high heat may burn the bread while keeping the cheese unmelted.
• Less is More – Stick to a single layer of fillings to make flipping easier and to avoid a messy sandwich.

Now that you have all the Sourdough Pesto Grilled Cheese ingredients ready, let’s get cooking!

Step‑by‑Step Instructions for Sourdough Pesto Grilled Cheese

Step 1: Prepare Ingredients
Begin by patting the fresh mozzarella dry with a paper towel to remove excess moisture, ensuring a perfectly gooey filling. Next, spread a generous layer of butter on one side of each slice of thick-cut sourdough bread. This layer will help achieve a beautifully crisp crust when grilling the sandwich.

Step 2: Assemble Sandwiches
In a skillet over medium-low heat, place one slice of sourdough butter-side down. Layer the mozzarella slices on top, followed by a spread of basil pesto. If desired, add sun-dried tomatoes and cooked bacon for extra flavor. Cap it with another slice of mozzarella, then top with the second slice of sourdough, ensuring the buttered side is facing up.

Step 3: Cook Sandwich
Heat the skillet gently, letting the Sourdough Pesto Grilled Cheese sizzle. Cook for about 3–4 minutes, or until the bottom slice of bread turns a rich, golden brown. As the bread toasts, the cheese should begin to melt, filling the sandwich with oozy goodness. Keep the heat low to avoid burning while achieving the perfect melt.

Step 4: Flip and Continue Cooking
Using a spatula, carefully flip the sandwich over when the bottom is crisp and golden. Allow the second side to cook for an additional 3–4 minutes. Keep an eye on the sandwich; both sides should be toasted to a delightful brown, and the cheese inside should be fully melted and oozy when done.

Step 5: Serve and Enjoy
Once both sides of the Sourdough Pesto Grilled Cheese are beautifully golden, remove the sandwich from the skillet. Allow it to cool for a minute before cutting it in half. This resting time lets the gooey mozzarella set slightly, making for a less messy bite. Enjoy your crispy, cheesy bliss warm and fresh!

How to Store and Freeze Sourdough Pesto Grilled Cheese

Fridge: Store leftover Sourdough Pesto Grilled Cheese in an airtight container for up to 2 days. This keeps it fresh while minimizing moisture build-up.

Freezer: If you want to freeze the assembled sandwiches, wrap them tightly in plastic wrap or aluminum foil, then place them in a freezer-safe bag for up to 1 month.

Reheating: To reheat, place the sandwich in a preheated skillet over medium heat until it’s heated through and the bread is crispy, about 4-5 minutes on each side. Alternatively, warm in an oven at 350°F for 10-15 minutes.

Make-Ahead Tip: Prepare the sandwich filling in advance and store it in the fridge. Assemble and grill when you’re ready to enjoy a freshly made Sourdough Pesto Grilled Cheese!

Vegetarian Delight: Skip the bacon and load up on fresh veggies. Sautéed spinach or bell peppers can add a delightful crunch and freshness to the sandwich.
Herb Infusion: Enhance the flavor further with a sprinkle of fresh herbs like basil or oregano inside the sandwich before grilling. This simple addition lends a burst of aromatic goodness.
Heat it Up: Add a few slices of jalapeños or a dash of red pepper flakes for those who enjoy a spicy kick. The heat will perfectly complement the creamy mozzarella and rich pesto.

Make Ahead Options

These Sourdough Pesto Grilled Cheese sandwiches are a fantastic meal prep solution for busy cooks! You can assemble the sandwiches up to 24 hours in advance by layering the sliced mozzarella, basil pesto, and optional sun-dried tomatoes and bacon between buttered sourdough slices. However, keep the butter separate until you’re ready to grill to maintain that perfect crispiness. Store the prepared sandwiches in the refrigerator, wrapped tightly to prevent drying out. When it’s time to enjoy your delicious creations, simply heat a skillet and grill each sandwich over medium-low heat until golden brown on both sides and the cheese is melty. This way, you’ll savor restaurant-quality results with minimal effort!
