Prepare the Chicken:

• Preheat your oven to 400°F (200°C) if baking, or heat a large skillet over medium-high heat if pan-searing.

• Season the chicken breasts with olive oil, salt, and pepper.

Cooking the Chicken:

• Baking: Place the chicken breasts on a baking sheet and spread a thin layer of pesto on top of each chicken breast. Bake for 20-25 minutes, or until the internal temperature of the chicken reaches 165°F (74°C).

• Pan-Seared: Heat olive oil in a skillet over medium-high heat. Add the chicken breasts and cook for about 6-7 minutes per side until browned and cooked through. After flipping the chicken, spread a spoonful of pesto on top of each chicken breast and cook for an additional 1-2 minutes to warm the pesto.

Prepare the Pesto (if making homemade):

• In a food processor or blender, combine the basil leaves, pine nuts, garlic, and Parmesan cheese.

• With the food processor running, slowly stream in the olive oil until the pesto reaches your desired consistency.

• Season with salt and pepper to taste.

Serve the Chicken:

• Once the chicken is cooked, remove it from the oven or skillet and top with additional Parmesan cheese (if desired). Let the chicken rest for a few minutes before serving.

• Optionally, garnish with fresh basil leaves.
