Melt the butter in a small pot over low heat on the stove. Pour your favorite brand of traditional hot sauce into the pot, and stir with the butter until combined. Let the sauce heat until bubbling as you stir the sauce for about an extra minute. Remove the pot from the heat at set the buffalo sauce aside to cool and thicken a little. If you’d like to make more buffalo sauce for the recipe, just make a 1:1 ratio of butter and hot sauce.
Prepare 5-ounce chicken breasts by patting them dry with a paper towel and rubbing olive oil into the flesh. Season the chicken breast(s) with salt, pepper, onion powder, garlic powder, and oregano. Heat a clean pan on high heat. Once the pan is hot, place the chicken in the pan seasoned side down. Use a marinade brush to brush some of the buffalo sauce onto the exposed side of the chicken in the pan.
Cook the chicken undisturbed until it chars on one side. Then, flip the chicken over so the buffalo sauce you brushed on sears into the meat. Brush more buffalo sauce over the newly exposed side of the chicken breast. Again, let the chicken cook undisturbed for about 3 minutes. Reduce the stove heat to a lower temperature, and pour all remaining buffalo sauce into the pan. Flip the chicken breast over in the sauce back and forth until sauce is coating the chicken as it thickens. Serve hot.
