Ingredients You’ll Need
This recipe shines because of its simple yet essential ingredients, each playing a crucial role in delivering a sandwich full of texture, freshness, and rich flavor. Getting these basics right sets the stage for a truly unforgettable lunch or dinner.
- Sourdough bread: Choose thick, sturdy slices to hold all the fillings without getting soggy.
- Cooked chicken breast: Tender and mild, perfect for layering flavors.
- Basil pesto: A fragrant, herbal punch that brings brightness and depth.
- Provolone or mozzarella cheese: Melts beautifully for that gooey, irresistible texture.
- Tomato: Adds juiciness and a hint of acidity to balance the richness.
- Fresh baby spinach leaves: Offers a mild, fresh crunch and a pop of green color.
- Mayonnaise: Creates a creamy barrier on the bread for moisture and subtle tang.
- Butter, softened: Ensures a golden, crispy crust when grilled.
How to Make Gourmet Chicken Pesto Sourdough Sandwich Recipe
Step 1: Prepare the Bread and Spreads
Start by spreading mayonnaise on one side of all eight slices of sourdough bread. This creamy layer not only adds moisture but also helps keep the bread from getting soggy once the ingredients are stacked. Next, spread the basil pesto generously on the other side of four slices, which will be the base of your sandwich fillings.
Step 2: Layer the Ingredients
On those pesto-slathered bread slices, layer the cooked chicken breast, making sure to distribute it evenly to every bite. Follow with slices of provolone or mozzarella cheese, then add the sliced tomato and a hearty handful of baby spinach leaves. This combination introduces layers of flavor and texture that make the sandwich dynamic and satisfying.
Step 3: Assemble the Sandwiches
Top each prepared slice with the remaining slices of bread, mayo side facing outward. This ensures both outer sides can be buttered for grilling. Gently press them together so the fillings stay in place when cooking.
Step 4: Grill to Perfection
Heat a skillet or griddle over medium heat. Butter the outsides of your sandwiches generously—this is what creates that irresistible golden crust. Place the sandwiches on the heated pan and cook for about 3 to 4 minutes on each side. Press gently with a spatula to help the cheese melt evenly and the bread toast to a perfect crunch.
How to Serve Gourmet Chicken Pesto Sourdough Sandwich Recipe

Garnishes
A sprinkle of freshly cracked black pepper or a small handful of fresh basil leaves can elevate the visual appeal and add a fresh aromatic note that complements the pesto beautifully.
Side Dishes
This sandwich pairs wonderfully with a crisp green salad tossed in a light vinaigrette or some crunchy kettle-cooked potato chips for contrast. Sweet potato fries or a simple tomato soup add comforting variety to round out your meal.
Creative Ways to Present
Cut the sandwich diagonally to expose the colorful layers inside, then stack or lean the halves against each other on a rustic wooden board. For a fun twist, try adding avocado slices or swap spinach with peppery arugula to cater to different palates.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftover sandwiches, wrap them tightly in plastic wrap or aluminum foil and store in the refrigerator for up to two days. This keeps the flavors intact though the texture will be best fresh.
Freezing
While you can freeze these sandwiches, the texture of fresh tomato and spinach may suffer upon thawing. To minimize this, assemble everything except the tomato and spinach, freeze the sandwiches wrapped well, then add fresh greens and tomato slices just before reheating and serving.
Reheating
To reheat, unwrap the sandwich and place it in a preheated skillet over low heat, turning gently until warmed through and the cheese melts again. Avoid microwaving to keep the bread from getting soggy.
FAQs
Can I use other types of bread?
Absolutely! While sourdough provides the best texture and flavor balance, ciabatta or a hearty multigrain loaf can also make delicious alternatives for this sandwich.
Is rotisserie chicken a good shortcut?
Yes, rotisserie chicken works perfectly if you want to save time without sacrificing flavor. Simply shred or slice the chicken and proceed as usual.
Can I make this sandwich vegetarian?
Definitely! Substitute the chicken with grilled vegetables like zucchini or roasted red peppers, and consider adding a bit more pesto or some sliced mozzarella for extra richness.
What cheese works best for melting?
Provolone and mozzarella are both excellent for melting smoothly without overpowering the other flavors. Feel free to experiment with fontina or gouda if you want a twist.
How do I avoid soggy bread?
Spread mayo on the cut sides of the bread as a moisture barrier, and make sure to toast the sandwich until the bread is golden and crispy. Assemble ingredients just before grilling to keep things fresh.
