Generously coat the chicken pieces with Cajun seasoning. In a large skillet over medium-high heat, add oil and sear the chicken for about 4-5 minutes on each side until golden brown. Transfer to a plate and set aside.

Reduce heat to medium and add chopped onion, bell peppers, and minced garlic. Sauté for 5-7 minutes until vegetables are softened. Sprinkle more Cajun seasoning over the mixture.

Add uncooked rice to the pan and stir gently for about 1 minute to toast the rice.

Pour in the chicken broth, stir, and bring to a gentle simmer. Nestle the seared chicken back into the skillet.

Reduce heat to low, cover the skillet, and let cook for 20-25 minutes until rice is tender and chicken is cooked through.

Remove from heat, let sit covered for 5 minutes, fluff the rice, and garnish with parsley or green onions. Squeeze fresh lemon juice if desired.
