Every bite is a melody of crisp, creamy, and tangy notes that will make you feel like a sandwich genius in under 20 minutes flat.

Ingredients You’ll Need
With just a handful of kitchen staples and a few fresh market gems, this sandwich delivers big on taste and texture. Each ingredient plays a crucial role in building those irresistible layers you’ll want to savor bite after bite.
- Sourdough Bread: Opt for slices that are sturdy enough to crisp up without falling apart, lending a slight tang that perfectly balances the richness of the filling.
- Butter (for toasting): Helps to create that golden, crunchy crust that makes each mouthful sing.
- Basil Pesto: The herby backbone of the sandwich; use your favorite brand or homemade for extra freshness.
- Cooked Chicken Breast (sliced or shredded): The star protein; rotisserie or leftover grilled chicken works perfectly and makes assembly extra quick.
- Fresh Mozzarella or Provolone: Creamy cheese that melts gently, wrapping everything in its mild, milky hug.
- Tomato Slices: Add juicy brightness—go for ripe, in-season tomatoes if you can.
- Arugula or Baby Spinach: A handful of greens adds crunch and a little peppery punch.
- Salt & Black Pepper: A sprinkle sharpens and elevates all the flavors.
- Balsamic Glaze (optional): A sweet-tart drizzle to finish that takes things to pure gourmet status.
How to Make Gourmet Chicken Pesto Sourdough Sandwich
Step 1: Build the Base Layer
Take your first slice of sourdough and butter one side generously. Flip it over so the unbuttered side is facing up, and spread a lush layer of basil pesto right to the edges. This ensures every bite is bursting with rich, herby flavor.
Step 2: Layer the Filling
On top of the pesto, pile on your sliced or shredded chicken breast, creating a hearty foundation. Follow with those creamy slices of mozzarella or provolone cheese, then tuck in your juicy tomato rounds, and finish with a big handful of arugula or baby spinach. Don’t forget a light sprinkle of salt and black pepper to make everything pop!
Step 3: Top and Prep for the Skillet
Place your second slice of bread on top, buttered side out, to seal the sandwich. The butter forms that irresistible crispy exterior we all crave.
Step 4: Grill to Golden Perfection
Heat a skillet over medium heat. Gently lay your stacked sandwich in the pan, then grill for 3–4 minutes per side. Press down lightly so everything melds and the cheese gets gorgeously gooey. You’re aiming for deeply golden bread and a warm, melty center.
Step 5: Serve the Gourmet Chicken Pesto Sourdough Sandwich
Transfer the sandwich to a cutting board and let it rest a moment before slicing. If you’re feeling extra fancy, drizzle with a little balsamic glaze for dramatic, tangy flair. Serve immediately while it’s gloriously warm and crisp!

Make Ahead and Storage
Storing Leftovers
If you have leftover Gourmet Chicken Pesto Sourdough Sandwich (lucky you!), wrap it snugly in foil or airtight container and refrigerate. It’ll keep for up to a day, though the bread may lose some crispness.
Freezing
You can make these sandwiches in advance and freeze before grilling—assemble as directed, wrap, and freeze. Grill from thawed for a fresh-made taste with no loss of flavor or texture.
Reheating
Bring your refrigerated (or thawed) sandwich back to life by reheating in a skillet over low heat, pressing gently until the crust is crisp and the cheese is melty again. Avoid microwaving, as it may make the bread chewy.
FAQs
Can I use a different kind of bread for the Gourmet Chicken Pesto Sourdough Sandwich?
Absolutely! While sourdough brings a wonderful tang and crunch, focaccia or ciabatta are excellent swaps that soak up those delicious juices just as well.
What’s the best chicken to use?
Rotisserie chicken is a time-saver and has beautiful flavor, but any cooked chicken breast—grilled, poached, or roasted—will shine in your Gourmet Chicken Pesto Sourdough Sandwich.
How can I make this sandwich vegetarian?
Simply skip the chicken and pile on extra vegetables—think grilled zucchini, roasted red peppers, or sliced avocado—for an equally satisfying and flavorful experience.
Can I make the sandwich ahead of time for a picnic?
Definitely! Assemble the Gourmet Chicken Pesto Sourdough Sandwich and wrap tightly before heading out. For best results, grill on-site if you can, or eat within a couple of hours to enjoy the best texture.
Is there a dairy-free version?
Of course! Swap the mozzarella or provolone for your favorite dairy-free cheese, and use a vegan butter. Many store-bought pestos now have vegan versions, too.
