Prepare 4-ounce chicken breasts by patting them dry with a paper towel and pounding them flat, if necessary. Your chicken breasts should be around ½-inch thick. Rub ¼ teaspoon olive oil into each breast, and season the chicken with salt, pepper, oregano, thyme, basil garlic powder, and onion powder. Heat a pan on your stove on very high heat. Once the pan is hot, place the chicken in the pan to sear.
Sear your chicken on each side, but don’t cook the chicken all the way through. You’ll finish cooking the chicken in the oven. Transfer the seared chicken to a well-seasoned sheet tray, and turn on the oven to preheat to 350 degrees. Spread ½ tablespoon marinara sauce across the top of each chicken breast. Follow up with 1 teaspoon bacon bits, 4 slices of thin-sliced pepperoni, and 1 ounce of whole-milk mozzarella in that order on each piece.
Place the pizza chicken in your oven. Bake the chicken for 15 minutes or until a meat thermometer reads 165 degrees internally and the cheese is completely melted. At your discretion, you can cook the pizza chicken under a broiler at the end of the recipe to give a more golden-brown top, just like a pizza coming out of the oven. Additional toppings you can include with your pizza chicken (also at your discretion) are chopped basil, grated parmesan cheese, or crushed red pepper flakes.
