Step 1

Begin by removing two boneless chicken breasts from the fridge and bring them to room temperature (about 15-20 minutes).

Step 2

Preheat your oven to 350 degrees.

Step 3

While you wait, prepare your spice rub. Combine the 1/2 tsp garlic powder, 1/2 tsp onion powder, 1 tsp paprika, 1/2 tsp dried rosemary, 1/2 tsp parsley, 3/4 tsp salt, and 1/8 black pepper in a small bowl. Use a fork to mix.

Step 4

Preheat the cast iron pan on the stovetop to medium heat

Step 5

On a cutting board, trim off any extra bits on the chicken breasts and pat dry with a paper towel. Generously sprinkle the spice rub on both sides of the chicken breasts.

Step 6

Pour a little oil to coat the entire bottom of the cast iron skillet (about 1-2 tablespoons)

Step 7

Sear the first side of the chicken breast in the hot oil for 5 minutes (Leave it be! Allow it to cook untouched to get that nice sear on the chicken)

Step 8

Flip to the other side and cook the chicken breast for an additional 5 minutes.

Step 9

Once seared on both sides, finish cooking in the oven for another 5-10 minutes (depending on thickness. See notes below)

Step 10

Remove the cast iron from the oven and let the chicken rest for 5-10 minutes before slicing.
