How to Make Best Pesto Grilled Cheese
-
Prepare Ingredients: Lay out two slices of sourdough in a clean frying pan (if space allows, you can use four for two sandwiches). Prepare your toppings nearby to streamline assembly.
-
Butter the Bread: Generously spread butter on the top side of each slice, then flip them to position the butter side down in the pan. This will help achieve that perfect golden crust.
-
Layer Cheese and Pesto: On each slice, layer 3-4 slices of mozzarella, followed by a heaped tablespoon of basil pesto. If you’re including sun-dried tomatoes or bacon, sprinkle them on top, then finish with another layer of mozzarella cheese.
-
Assemble Sandwiches: Top each with another slice of sourdough and gently press down to help the fillings adhere together.
-
Cook to Perfection: Butter the outer sides of the sandwiches, then heat the pan over medium-low. Cook until golden brown, flipping once the bottom crisps up and the cheese begins to melt, usually about 3-4 minutes per side.
-
Slice and Serve: Remove the sandwiches from the pan and let them cool slightly before slicing. Serve warm to enjoy that gooey, melty goodness!
Optional: Garnish with fresh basil leaves for an extra pop of flavor.

Expert Tips for the Best Pesto Grilled Cheese
-
Choose Fresh Sourdough: Use fresh, thick-cut sourdough to ensure your sandwich maintains a crispy exterior and soft interior without being overly airy or sour.
-
Pat the Mozzarella Dry: Always pat the mozzarella dry before adding it to the sandwich. This prevents excess moisture that can lead to a soggy Best Pesto Grilled Cheese.
-
Control Pesto Quantity: Use basil pesto sparingly; too much can make the sandwich sloppy. A heaped tablespoon on each layer is just enough for vibrant flavor without sogginess.
-
Medium-Low Heat Cooking: Cook on medium-low heat to prevent burning while allowing the cheese to melt evenly, ensuring the sandwich is perfectly golden and gooey.
-
Avoid Overfilling: Don’t overcrowd your sandwich with too many add-ins. While extras like sun-dried tomatoes and bacon are delicious, too many fillings can lead to a messy result and hinder perfect melting.
-
Let It Cool, Then Cut: Allow the sandwich to cool slightly after cooking before slicing. This helps the cheese firm up a bit, making for a cleaner cut and a more enjoyable bite!

Best Pesto Grilled Cheese Recipe FAQs
How do I know if the sourdough bread is fresh enough to use?
Absolutely! To ensure your sourdough is fresh, look for a crust that’s crispy and a soft, slightly chewy interior. If the bread has dark spots all over or feels overly dry, it’s best to choose a different loaf for that ideal texture in your Best Pesto Grilled Cheese.
What’s the best way to store leftover grilled cheese sandwiches?
Very easy! Store your cooked sandwiches in an airtight container in the fridge for up to 2 days. When you’re ready to enjoy again, simply reheat them on a skillet over low heat, which helps restore that crispy exterior. You’ll have a warm, melty delight just like fresh!
Can I freeze the Best Pesto Grilled Cheese?
Of course! If you’ve made extra sandwiches, wrap each one tightly in plastic wrap and again in foil, then freeze them for up to 3 months. To reheat, thaw the sandwiches in the fridge overnight. For optimal results, cook them over medium-low heat in a skillet until the cheese is melty and the bread is crispy again. This method helps maintain the sandwich’s integrity.
Is it possible to customize the ingredients for dietary restrictions?
Absolutely! This recipe is very flexible. If you’re looking for a vegetarian option, simply omit the bacon and consider adding some grilled vegetables or extra cheese. Always check to make sure your pesto is made without nuts if there are allergies, and feel free to swap out the mozzarella for a lactose-free variety if needed.
What if my grilled cheese ends up soggy?
No worries, it happens! If your sandwich turns out soggy, it might be due to too much moisture from the pesto or the cheese not being patted dry. To counter this while cooking, make sure to use a light hand with the pesto, and thoroughly dry the mozzarella before adding it to the sandwich. Cooking over medium-low heat will also help prevent any burning while allowing everything to melt just perfectly.
Can I prepare the sandwiches in advance?
Yes, you definitely can! If you’re looking for a quick meal, feel free to assemble the uncooked sandwiches and store them in the fridge for up to 24 hours. When you’re ready to cook, simply heat them in a skillet. This way, you can have a delicious meal ready to go in under 15 minutes!
