This comforting Cajun Chicken and Rice Casserole brings together juicy chicken, sweet peppers, celery, and fluffy rice all baked in a creamy, boldly seasoned sauce. It is the kind of dish that fills the house with tantalizing Southern aromas and makes family mealtime feel special, no matter how rushed the weeknight.
I first whipped this up when I needed a big flavorful dinner for visiting friends and it instantly became my most-requested casserole. Even picky kids have cleaned their plates every single time.
Ingredients
- Boneless skinless chicken thighs or breasts: Brings hearty protein and stays tender throughout baking I love using chicken thighs for more juicy flavor
- Olive oil: Helps the spice mix stick to the chicken and brings rich undertones Choose a fruity or mild olive oil for best results
- Cajun seasoning: Adds that signature bold warmth You can use store-bought or mix your own for even fresher flavor
- Yellow onion: Sweetens as it bakes and forms a base Be sure your onion feels heavy and firm
- Red and green bell peppers: Layer in vivid color and balancing sweetness Look for peppers with shiny skins and no soft spots
- Celery: Delivers a welcome crunch Use fresh stalks from the heart for most flavor
- Garlic: Deepens and rounds out all the other flavors Use plump cloves with tight skin
- Long-grain white rice: Soaks up all the juices for tender fluffy grains Rinse well to ensure the rice cooks evenly and does not get gummy
- Low-sodium chicken broth: Keeps everything moist and flavorful without over-salting You want a broth with clear golden color and a savory aroma
- Diced tomatoes: Adds brightness slight acidity Drain well to prevent excess liquid
- Heavy cream: Makes the casserole extra creamy For a lighter take use half-and-half
- Shredded cheddar cheese: Creates the bubbly golden top layer Go for sharp cheddar or mix in Monterey Jack for more melt
- Fresh parsley: Finishes the dish with herby freshness Bright green leaves signal best flavor
- Salt black pepper cayenne pepper: These balance the flavors and bring customizable heat Taste as you go so it is seasoned just right
Instructions
- Preheat the Oven:
- Bring your oven up to 375 degrees Fahrenheit and have a 9 by 13 inch baking dish greased and ready This step ensures even cooking and prevents sticking
- Season the Chicken:
- Combine the chicken pieces with olive oil and Cajun seasoning in a large mixing bowl Toss them thoroughly until every piece is evenly coated Coating the chicken with oil and spices first allows those flavors to permeate the meat
- Layer the Rice and Vegetables:
- Evenly spread rinsed rice across the bottom of your prepared dish Layer the diced onion bell peppers celery and garlic right on top This stacking lets the vegetables infuse the rice with savor and sweetness as it bakes
- Arrange the Chicken:
- Scatter the seasoned chicken pieces in a single layer over the vegetables Putting the chicken on top ensures it cooks through and flavors everything below
- Mix and Pour the Sauce:
- Whisk chicken broth drained tomatoes heavy cream salt black pepper and a pinch of cayenne together in a bowl until well blended Carefully pour this mixture evenly over the entire casserole This liquid will soak down into the rice and bind everything as it bakes
- Bake Covered:
- Tightly cover your dish with foil and bake for 40 minutes This keeps moisture in so the rice cooks through and the casserole stays creamy
- Top with Cheese and Finish Baking:
- Take off the foil and sprinkle the shredded cheddar evenly over the top Slide it back in the oven uncovered and bake for another 10 to 15 minutes until the cheese is melted bubbling and starting to golden
- Rest and Garnish:
- Allow the casserole to rest out of the oven for at least 10 minutes before serving This helps all the creamy sauce settle so you get neat servings Sprinkle with fresh chopped parsley for a final flourish of color and brightness

My favorite part of this dish is scooping up big cheesy portions with melty edges and a hint of fresh parsley on top My sister and I often sneak bits of the crispy cheese topping before dinner is served just like when we were kids
Storage Tips
Store any leftover casserole in a tightly covered container in the refrigerator for up to four days It reheats best in the oven at 350 degrees until warmed through If the rice absorbs most of the sauce a splash of broth or cream when reheating helps revive the creamy texture
Ingredient Substitutions
Swap heavy cream with half-and-half for a lighter meal For a dairy-free option try canned coconut milk instead of cream Monterey Jack or pepper jack works well in place of cheddar and if you want a little smoky kick add cooked andouille sausage to the mix
Serving Suggestions
Pair this casserole with a crisp green salad or a side of steamed green beans For an extra Louisiana touch serve with garlic bread or even cornbread Muffins make a great side for soaking up extra sauce
Cultural and Seasonal Notes
This dish draws inspiration from classic Cajun flavors rooted in Louisiana home kitchens and brings big comfort to any table It is especially cozy to make in chilly months when you crave bold satisfying flavors but it works year round Substitute with summer bell peppers when in season for maximum sweetness
Seasonal Adaptations
Use local peppers and fresh tomatoes in summer Turn it into a fall dish by tossing in small cubes of roasted sweet potato Add spring asparagus or peas for extra green freshness
Success Stories
Friends and family rave about this casserole at potlucks and gatherings It is hearty enough for football parties and comforting enough for Sunday night suppers It freezes well so you can have a hot meal on busy days
Freezer Meal Conversion
Assemble the casserole fully but do not bake Cover tighten and freeze for up to two months When ready to cook thaw overnight in the refrigerator and bake as directed If baking from frozen add 10 to 15 minutes until hot and bubbling throughout

Patience truly pays off when it comes to achieving that perfect creamy texture The melty cheese topping is best enjoyed warm with a sprinkle of fresh parsley.
