Start by mixing water and salt in a large bowl, then submerge the chicken breasts. Let them sit for about 15 minutes to absorb moisture. If you have more time, refrigerate and brine for up to 6 hours for extra juiciness.
After brining, pat the chicken dry with paper towels. Coat each piece generously with olive oil or melted butter. This step gives the chicken golden edges and helps the spices stick evenly.
Mix salt, pepper, garlic powder, and smoked paprika in a small bowl. Sprinkle generously over the chicken, rubbing the seasoning in with your fingers to cover every surface. You can swap this mix with your favorite spice blend if you want a different flavor.
Preheat your oven to 450°F. Arrange the chicken in a baking dish, making sure the pieces aren’t touching. Bake for 15–18 minutes, depending on thickness. Check with an instant-read thermometer—165°F is the magic number for perfect doneness.
Once baked, move the chicken to a cutting board and loosely cover with foil. Let it rest for 5–10 minutes before slicing so the juices stay locked inside.
