What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 2 whole large chicken breasts
  • 2 tsp smoked paprika
  • 1 tsp cayenne pepper
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 2 tbsp unsalted butter

Step by step instructions

Step 1: Mix the Cajun Spice Rub

Combine smoked paprika, cayenne pepper, garlic powder, onion powder, salt, and black pepper in a small bowl. Coat each chicken breast generously on all sides with the spice blend, pressing it firmly into the meat.

Step 2: Heat the Cast Iron Pan

Place a cast iron skillet over high heat and allow it to get extremely hot for about 3 minutes. Add butter and let it melt and slightly brown before adding the chicken breasts.

Step 3: Blacken the Chicken

Add the spiced chicken breasts to the screaming hot pan and cook for 7 to 8 minutes per side. The exterior should form a dark, deeply charred crust while the inside remains juicy and reaches 165 degrees Fahrenheit.

Step 4: Rest and Slice

Transfer the blackened chicken to a plate and tent loosely with foil. Allow it to rest for 5 minutes before slicing against the grain to serve alongside your preferred sides.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • unsalted butter → ghee or avocado oil for a dairy-free option
  • cayenne pepper → chili powder for a milder heat level

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Using a non-stick pan which cannot withstand the extremely high heat needed for proper blackening
  • Adding too much butter which makes the spices slide off and prevents the crust from forming correctly
