This creamy Cajun chicken bake transforms ordinary chicken breasts into a spectacular dinner with minimal effort. The combination of homemade Cajun spices, sweet bell peppers, and creamy cheese creates a dish that's both comforting and exciting. I've been making this for my family on busy weeknights when I need something impressive that doesn't require hours in the kitchen.
I first discovered this recipe when searching for ways to use up bell peppers from my garden. What started as a kitchen experiment has become my go-to dish when entertaining friends who always ask for the recipe before leaving.
Ingredients
- Chicken breasts: small, tender cuts work best as they cook more evenly
- Bell peppers: thinly sliced for maximum flavor release and sweetness
- Cream cheese: adds incredible creaminess that melts into a silky sauce
- Cheddar cheese: creates that irresistible golden top that adds richness
- Paprika: the star of the Cajun seasoning that provides both color and smoky flavor
- Cayenne pepper: adjustable depending on your heat preference
- Oregano and thyme: dried herbs that add classic Cajun flavor notes
- Garlic: fresh minced cloves infuse the dish with aromatic goodness
Step-by-Step Instructions
- Prepare the Cajun seasoning:
- Combine paprika, cayenne pepper, oregano, thyme, and salt in a small bowl until well mixed. This homemade blend gives you complete control over the heat level and freshness that store-bought mixes often lack.
- Layer the pepper base:
- Spread your thinly sliced bell peppers evenly across the bottom of your casserole dish. This creates a flavorful bed that will catch all the delicious juices from the chicken as it cooks, essentially braising the peppers to sweet perfection.
- Position and season the chicken:
- Place chicken breasts directly on top of the pepper layer, then generously sprinkle with your homemade Cajun seasoning. Make sure to season all sides for consistent flavor throughout. Scatter minced garlic evenly over the chicken for an aromatic boost.
- Add the creamy elements:
- Top each chicken breast with cold cream cheese slices. Using cold cream cheese is crucial as it melts slowly during baking, creating a velvety sauce. Finish with a layer of shredded cheddar cheese which will form a beautiful golden crust.
- Bake to perfection:
- Cook uncovered at 375°F for 20-30 minutes until chicken reaches 165°F internally. The baking time varies depending on chicken thickness, so using a meat thermometer ensures perfect results. For extra color and texture, broil for the final 2 minutes.
- Serve and enjoy:
- Scoop those now-tender peppers from underneath the chicken and arrange them around and on top of the chicken for a beautiful presentation and complete flavor experience.

The cream cheese is truly the secret weapon in this recipe. When I accidentally doubled the amount once, my family declared it the best version ever. Now I always make sure to be generous with this ingredient for maximum creaminess.
Storing Leftovers
This Cajun chicken actually tastes even better the next day after the flavors have had time to meld together. Store in an airtight container in the refrigerator for up to three days. To reheat, cover with foil and warm in a 325°F oven for about 15 minutes to prevent the chicken from drying out. The microwave works too but might slightly alter the texture of the cheese.
Ingredient Substitutions
This recipe is wonderfully adaptable to what you have on hand. Boneless chicken thighs make an excellent substitute for chicken breasts, offering even more moisture and flavor, though they may require a slightly longer cooking time. For the cheese lovers who want to experiment, Monterey Jack provides a milder flavor while pepper jack adds an extra kick of heat. Plant-based cream cheese works surprisingly well for those avoiding dairy, though the sauce won't be quite as rich.
Serving Suggestions
While this dish is complete on its own, serving it with simple sides elevates the meal. Cauliflower rice makes an excellent low-carb accompaniment that soaks up the creamy sauce beautifully. For those not counting carbs, crusty French bread for sauce-dipping is absolutely divine. A simple side salad with a light vinaigrette provides a fresh contrast to the rich, creamy main dish. When entertaining, I often serve this with roasted asparagus and a chilled Sauvignon Blanc.

The Origins of Cajun Flavor
Cajun cuisine originated with the Acadians, French colonists who settled in Louisiana after being expelled from what is now Nova Scotia. Traditional Cajun cooking emphasizes local ingredients, simple preparation, and bold flavors. The spice blend in this recipe captures the essence of Cajun cooking while adapting it for modern home kitchens. Unlike traditional Cajun dishes that might involve making a roux or long simmering times, this version delivers authentic flavors in a fraction of the time.
