How to Make Pesto Chicken Sandwich on Sourdough?
Step-by-step guidance to ensure a perfectly cooked, flavorful sandwich every time.
Step 1: Prepare the Chicken
Start by placing the chicken breasts between two layers of plastic wrap or in a large disposable plastic bag. Use a meat mallet or rolling pin to pound them to an even thickness, ensuring they cook uniformly. Season both sides with Italian seasoning, salt, and pepper. This step not only tenderizes the meat but also infuses it with flavor.
Step 2: Cook the Chicken
Heat a skillet or grill pan over medium heat. If using a skillet, lightly grease the surface with cooking spray or a drizzle of olive oil. Cook the chicken breasts for 5 to 8 minutes per side, until an instant-read thermometer inserted into the centers reads 165°F (74°C). Transfer the chicken to a cutting board and let it rest for 5 minutes before slicing it into 1/2-inch wide strips.
Step 3: Assemble the Sandwiches
While the chicken rests, prepare the bread. Spread mayonnaise (if using) and 2 tablespoons of pesto on each slice of sourdough bread. Layer the sliced chicken, tomato slices, and Swiss cheese on four of the bread slices. Top with the remaining bread slices, pesto side down, to form sandwiches.
Step 4: Toast the Sandwiches
Brush the outsides of the sandwiches lightly with olive oil or a thin layer of mayonnaise. Heat a skillet over medium heat and toast the sandwiches until the bread is golden brown and the cheese has melted, about 3 to 4 minutes per side. Press down gently with a spatula to ensure even browning.
Additional Tips for Making this Recipe Better
Small tweaks can make this sandwich even more delicious.
- I find that using fresh, homemade pesto elevates the sandwich’s flavor, but store-bought pesto is a convenient alternative.
- If you prefer a crispier texture, consider grilling the sandwiches in a panini press.
- For added richness, spread a thin layer of mayonnaise on the inside of the bread before adding the pesto.
- Letting the chicken rest before slicing helps retain its juices, keeping the sandwich moist.
- If you’re short on time, pre-cooked chicken slices can be used to assemble the sandwich quickly.
How to Serve Pesto Chicken Sandwich on Sourdough?

Finish by garnishing with a few fresh basil leaves, which not only add a pop of color but also enhance the aroma and flavor, making each bite irresistible.
