Preheat your oven to 375F/190C. This is essential for ensuring the chicken cooks evenly and the cheese melts beautifully.
While the oven is heating, take the four large chicken breasts and trim away any unwanted fatty or undesirable parts. This will help in achieving a tender end result.
Rub the Greek Seasoning all over the chicken on both sides. Make sure to cover every inch to enhance its flavor.
In a frying pan, heat the olive oil over medium-high heat. Once hot, add the seasoned chicken breasts and cook for about 2 minutes on one side. You’re looking for a slight brown color, which indicates it’s starting to sear nicely.
Carefully turn the chicken over and cook for another few minutes on the other side. Be cautious not to overcook it now, as it will continue to bake in the oven.
Once cooked, remove the chicken to a cutting board and let it cool for a minute or two until it’s manageable to handle.
While the chicken cools, drain the olives and slice them, halve the cherry tomatoes, and slice the peperoncini. Crumble the Feta Cheese to have everything ready for assembly.
Next, cut each chicken breast lengthwise into 3 to 4 strips. This will help with even distribution in the dish.
Spray your casserole dish (an 8"x13" or 9"x12") with non-stick spray to prevent sticking. Arrange the chicken strips going crosswise in the dish.
Now, sprinkle the sliced tomatoes, olives, and peperoncini over the chicken strips. Crumble the Feta Cheese over the top of it all.
Season to taste with fresh-ground black pepper, enhancing the overall flavor.
Place the casserole dish in the preheated oven and bake for about 25 minutes. You’re looking for the chicken to be heated through and the cheese to start melting beautifully.
To ensure safety, you can use an Instant Read Meat Thermometer to check the internal temperature of the chicken. It should reach 165F/75C.
Once done, serve the Greek Chicken Bake hot, and enjoy a delightful meal with your loved ones!
