Combine the steak seasoning, smoked paprika, and sweet paprika in a bowl. Coat the chicken breasts liberally with the seasoning on all sides.
Add the cooking oil to a large skillet and heat over medium-low (or medium for thin-cut breasts). Once hot, swirl the oil to coat the skillet.
Add the chicken breasts to the skillet and cook for about 8 minutes without flipping (5 minutes for thin-cut breasts). Flip the chicken and then cook on the second side until well browned and cooked through (internal temperature of 165ºF).
For extra luscious chicken, add a tablespoon of butter to the skillet, allow it to melt, then flip the chicken a couple of times to coat in the melted butter.
Transfer the chicken to a clean cutting board and allow it to rest for five minutes before slicing and serving.
