Start by patting dry chicken breasts with paper towels. You can slice each chicken breast in half to make them cook faster, I kept them whole.
Brush them with oil and season them generously on both sides with the blackened chicken seasoning.
In a large skillet, add the olive oil (or vegetable oil), and heat the oil over medium-high heat. Add the chicken to the pan and cook them on each side for 8-10 minutes.
The chicken is ready when the internal temperature reaches 165f (74c). Use a meat thermometer to know for sure but it's not a must. You can also cut the chicken to check its doneness.
Remove the chicken from the pan to allow it to chill for 5 minutes before slicing them.
Use a sharp knife to slice the chicken, and serve it with your favorite side dish and a squeeze of fresh lemon.
Notes
Do not disturb the chicken! Let the chicken cook for at least 5 minutes without flipping it so it will have time to properly form a crust.
Start with quality chicken: Use fresh, high-quality chicken breasts for the best results in your blackened chicken dish.
Dry the chicken with paper towels before you rub it with the spices. This ensures you have perfect crispy skin on the outside and tender meat on the inside.
Season generously. Coat the chicken with a a generous amount of the blackened seasoning for a lot of delicious flavor.
Preheat your skillet. Make sure your skillet is hot before adding the seasoned chicken to ensure a nice sear and crust on the outside.
Use butter or oil. Brush the skillet with butter or oil to prevent sticking and help create that perfect blackened crust.
Use your favorite part of chicken. Like chicken thighs, chicken tenders, and chicken cutlets. Ensure that you clean the chicken and that there are no bones for easy eating.
Start to cook on high heat. Blackened chicken is all about that charred exterior, so cook it over high heat for a short period to lock in juices while creating a crispy coating.
Don't overcrowd the pan! Cook the chicken in batches if necessary to avoid overcrowding, which can lead to steaming instead of searing.
Resist the urge to constantly flip the chicken. let it cook undisturbed until you achieve that beautiful blackened crust on one side before flipping.
Rest before slicing. Allow the cooked chicken to rest for a few minutes before slicing into it - this helps retain its juices and ensures tenderness.
Use a meat thermometer to ensure that your chicken is cooked on the inside and prevent your chicken from drying out. The chicken is ready when it reaches 165f (74c).
