Sourdough Pesto Grilled Cheese Ingredients
For the Sandwich

• Mozzarella Cheese – Offers that melty, creamy texture; pat dry beforehand to avoid sogginess.
• Basil Pesto – Adds a fresh, herby flavor; remember to use sparingly to prevent excess moisture.
Optional Add-Ons
• Sun-Dried Tomatoes – Enhance flavor complexity with their sweet, tangy notes and they work beautifully with a Sourdough Pesto Grilled Cheese.
• Bacon – Adds savory richness; ensure it’s cooked and chopped beforehand for convenience.
For Grilling
• Butter – Essential for achieving a crisp outer layer; spread it on the bread slices before grilling for optimal results.
Step‑by‑Step Instructions for Crispy Sourdough Pesto Grilled Cheese
Step 1: Prepare the Sandwich Base
Begin by placing two thick slices of sourdough bread in a cold frying pan. This helps to ensure an even toasting. Once positioned, spread a generous layer of butter on the top side of each slice, allowing the richness to seep in as it heats.
Step 2: Build the Cheese Layer
Gently flip the bread to have the buttered sides facing down. Layer 3-4 thin slices of mozzarella cheese evenly over each slice, ensuring maximum coverage for that gooey effect. The cheese should start to soften as the heat builds, inviting in that comforting melting goodness.
Step 3: Add the Pesto
Take a heaped tablespoon of basil pesto and spread it over the mozzarella on both slices. This vibrant layer adds a fresh, herby flavor that elevates your crispy sourdough pesto grilled cheese. Make sure to distribute it evenly, ensuring every bite is packed with flavor.
Step 4: Optional Enhancements
If you’re feeling indulgent, sprinkle some chopped sun-dried tomatoes and crispy bacon over the pesto for added layers of flavor. These optional ingredients enhance the complexity of the sandwich, creating a delightful contrast with the melty mozzarella.
Step 5: Double the Cheese
To ensure your sandwich is irresistibly gooey, add another layer of mozzarella cheese over the toppings. This additional layer not only enhances the cheesiness but also helps to bind all the ingredients together once cooked, creating that ultimate grilled cheese experience.
Step 6: Form the Sandwich
Carefully place a second slice of sourdough bread on top, pressing down gently to combine the flavors of your crispy sourdough pesto grilled cheese. This step is key, as it helps to keep all the delicious fillings tucked safely inside.
Step 7: Butter the Top Slice
Spread butter generously on the top slice of bread before cooking. This will create a beautifully golden and crisp exterior as the sandwich cooks, giving it that satisfying crunch with every bite.
Step 8: Cook to Perfection
Heat your pan on medium heat, allowing it to warm up gently. Cook the sandwich for about 3-4 minutes on each side, carefully checking for a golden brown color. You’ll know it’s ready when the cheese begins to ooze out and the bread is perfectly toasted.
Step 9: Flip and Finish
Once the first side is golden brown, gently flip the sandwich with a spatula. Cook for another 3-4 minutes until the other side is equally golden and crispy. The aroma will fill your kitchen, signaling that your crispy sourdough pesto grilled cheese is almost ready.
Step 10: Let It Rest
Remove the sandwich from the pan and let it cool for a minute or two before cutting. This brief cooling period helps the cheese settle, ensuring each slice holds its delicious shape when you serve it up to eager taste buds.
