Step 1: Preheat your oven to 450°F (232°C). This high temperature is the secret to locking in the juices of the Baked Chicken Breast.
Step 2: Pat the chicken breasts dry with paper towels to ensure the oil and seasonings adhere properly.
Step 3: If the chicken breasts are uneven in thickness, place them between two sheets of plastic wrap and gently pound the thickest part with a meat mallet until even.
Step 4: In a small bowl, mix together the salt, pepper, garlic powder, onion powder, smoked paprika, and oregano.
Step 5: Drizzle the chicken with olive oil and sprinkle the spice mix over both sides, rubbing it in thoroughly.
Step 6: Place the chicken on a rimmed baking sheet and bake for 15-20 minutes, or until the internal temperature reaches 160°F (71°C).
Step 7: Remove from the oven and transfer to a plate. Tent loosely with foil and let the Baked Chicken Breast rest for at least 5-10 minutes before slicing.
