Creating your incredible Cajun chicken is straightforward. Follow these steps:

1. Prep the Chicken: Rinse the chicken breasts under cold water and pat them dry with paper towels.
2. Mix the Marinade: In a bowl, combine olive oil, Cajun seasoning, garlic powder, onion powder, smoked paprika, cayenne pepper, lemon juice, salt, and pepper.
3. Marinate the Chicken: Place the chicken breasts in a resealable plastic bag. Pour the marinade over the chicken, ensuring it coats evenly. Seal the bag and refrigerate for at least 30 minutes.
4. Preheat the Grill or Oven: Preheat your grill to medium-high heat or preheat the oven to 400°F (200°C).
5. Cook the Chicken: If grilling, place the marinated chicken on the grill and cook for 6-8 minutes on each side, or until the internal temperature reaches 165°F (75°C). If baking, place the chicken on a greased baking sheet and bake for 20-25 minutes.
6. Rest the Chicken: Once cooked, remove the chicken from the grill or oven. Let it rest for about 5 minutes to keep it juicy.
7. Slice and Serve: Slice the chicken and serve immediately, garnished with fresh parsley if desired.

These steps will ensure your Cajun chicken turns out amazing every time, letting you savor each flavorful bite!
