Preheat your oven to 375°F (190°C).
Rub the chicken breasts with Cajun seasoning, ensuring they are well-coated.
Heat olive oil in a skillet over medium heat.
Sear the chicken breasts in the skillet for 5 minutes on each side until golden brown.
Remove the chicken and set aside.
In the same skillet, sauté the sliced bell pepper and onion until tender.
Add minced garlic and sauté for another minute.
Stir in the rice, followed by chicken broth, and bring to a boil.
Return the chicken to the skillet, cover, and transfer to the oven.
Bake for 20-25 minutes until the chicken is cooked through and the rice is fluffy.
