Pesto Spinach Stuffed Chicken are chicken breasts stuffed with gooey mozzarella cheese, sun dried tomatoes and spinach. Marinated in a yogurt and basil pesto sauce, they are moist and flavorful.
Prepare the chicken by using a very sharp knife and carefully cutting a pocket into the side of the chicken breast that is about 1/2" shy of cutting completely through the other side and ends.
Combine the chicken breasts, Greek yogurt, pesto and Kosher salt in an airtight plastic bag. Massage marinade into chicken breasts, including the pocket. Marinate in the refrigerator from 1 to 24 hours.
Preheat the oven to 375°F and line a baking sheet with aluminum foil or parchment paper.
Remove the chicken from the marinade, tapping to take off excess sauce. Discard marinade and place chicken onto the prepared baking sheet.
Bake for 20 minutes, remove from the oven. Cooking times may vary depending on the size of the chicken, so make sure they reach 160°F.
Using two forks, stuff each pocket with evenly divided mozzarella cheese, sun dried tomatoes and spinach. Return to the oven for 10 minutes.
Remove, allow to rest for 5 minutes and garnish with the fresh basil and Maldon sea salt.
