I always start by preheating the oven to 375°F (190°C). This step ensures that the chicken cooks evenly and stays juicy while the cheese develops that perfect golden finish.
In a small bowl, I mix paprika, cayenne, oregano, thyme, and salt to make the Cajun seasoning. Then, I coat the chicken breasts generously on all sides. This spice mix is the heart of the dish, giving the chicken its bold, signature flavor.
Once the chicken is seasoned, I place it on top of the peppers. Then I sprinkle over the minced garlic, add a couple of spoonfuls of cream cheese to each breast, and finish with a blanket of shredded cheddar.
The casserole dish goes into the oven for about 20–30 minutes, or until the chicken reaches 165°F (74°C). For an extra treat, I switch the oven to broil for the last two minutes so the cheese gets golden and bubbly.
Next, I slice the red and yellow peppers into thin strips and spread them across the bottom of the casserole dish. As they cook, they soften and caramelize, becoming the sweet base that balances out the Cajun spices.
When the dish comes out of the oven, it’s hot, cheesy, and full of flavor. I like to garnish with parsley or an extra sprinkle of cheddar. Each serving includes plenty of those sweet peppers along with the juicy chicken.
