Ingredients You’ll Need

Each ingredient in this Chicken Broccoli Rice Casserole with Creamy Cheddar and Boursin Recipe plays a role in building layers of flavor and texture. I always recommend using fresh broccoli and good quality cheeses to really bring this casserole to life. Here’s a quick rundown with a few tips for shopping and prepping:

  • Unsalted butter: Helps build a rich base for browning the chicken and adding flavor without extra salt.
  • Chicken thighs: They stay juicy and tender, plus they add deep flavor that works so well in casseroles.
  • Olive oil: Perfect for a light sear on the chicken before baking.
  • Garlic cloves: Fresh minced garlic packs way more punch than pre-minced.
  • Chicken stock: Adds savory depth to the sauce—don’t skip this!
  • Cream of chicken with herbs: The classic creamy base that makes everything feel cozy.
  • Heavy cream: Thickens and enriches the sauce when combined with the soup.
  • Cheddar cheese (mild or medium): Sharpness level depends on your preference—medium cheddar adds a nice tang.
  • Sour cream: Adds creaminess and a slight tang that cuts through the richness.
  • Boursin cheese: This is the secret weapon—herbed and garlicky, it elevates the flavor profile beautifully.
  • Bayou City all-purpose seasoning: Adds a bit of Cajun flair; use it sparingly to control heat.
  • Bayou City garlic pepper: Brings a savory, peppery kick to complement the dish.
  • Onion powder: For subtle sweetness and depth without overpowering the dish.
  • Cayenne pepper: A touch for warmth and mild heat—adjust to your spice tolerance.
  • Broccoli florets: Fresh and cooked just until tender brightens the casserole with color and crunch.
  • White rice: Cooked rice helps absorb all that wonderful creamy sauce.
  • Salt and pepper: To taste, but be mindful since the seasoning mix adds saltiness already.

Variations

I love how flexible this Chicken Broccoli Rice Casserole with Creamy Cheddar and Boursin Recipe is. You can easily switch things up based on what you have or dietary needs. Here’s some ways I’ve played around with it and encourage you to try too:

  • Swap chicken breasts for thighs: I’ve tried it and honestly, chicken thighs bring more flavor and stay moist better. But breasts work if you prefer leaner meat.
  • Use cauliflower rice instead of white rice: This is perfect if you want a lower-carb casserole and still get that satisfying texture.
  • Swap broccoli with asparagus or green beans: Depending on the season, I love experimenting with veggies that hold their texture after baking.
  • Make it spicier: Add extra cayenne or a dash of hot sauce to perk it up—just be cautious if serving kids!
  • Use smoked cheddar: For a smoky twist, I swapped mild cheddar for smoked once and it was incredible.

How to Make Chicken Broccoli Rice Casserole with Creamy Cheddar and Boursin Recipe

Step 1: Sear the Chicken to Lock in Juices

Start by heating the butter and olive oil in a large skillet over medium-high heat. Pat your chicken thighs dry and season with half the Bayou City all-purpose seasoning, garlic pepper, onion powder, cayenne, salt, and pepper. Sear the chicken for about 3-4 minutes per side until it’s golden brown but not fully cooked through—that’s important because it will finish baking in the casserole. This step locks in moisture and builds flavor, so don’t skip it!

Step 2: Build the Creamy Sauce Base

With the chicken removed, add minced garlic to the skillet and sauté for just about 30 seconds to release that amazing aroma. Pour in the chicken stock to deglaze the pan and scrape up any browned bits—this adds so much depth to the sauce. Next, combine the cream of chicken soup with heavy cream in a measuring cup and pour it into the skillet. Stir everything together and let it simmer gently for a couple minutes, then fold in the sour cream, cheddar cheese, and the Boursin cheese. The mixture should be silky and rich—if it’s too thick, add a splash more stock.

Step 3: Combine All Ingredients and Arrange in Baking Dish

In a large bowl, mix together the cooked broccoli, cooked white rice, and the creamy sauce. Add the peptide seasoning mixtures and stir gently to coat everything evenly. Lay the seared chicken thighs on top or tuck them evenly into the mixture in a greased 9×13 inch casserole dish. This helps the chicken absorb the flavors while baking.

Instructions

  1. Prepare the Chicken: Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season the chicken thighs with 2 tablespoons of Bayou City all-purpose seasoning and a pinch of salt and pepper. Place the chicken thighs in the skillet and cook until browned on both sides and fully cooked through, about 6-7 minutes per side. Remove the chicken from the skillet and set aside.
  2. Sauté the Garlic: In the same skillet, add 2 tablespoons of unsalted butter and the minced garlic. Sauté for 1-2 minutes until fragrant but not browned.
  3. Make the Creamy Sauce: Add the chicken stock, cream of chicken soup, and heavy cream (using the cream of chicken can to measure the cream) to the skillet. Stir well to combine and bring to a gentle simmer. Add the remaining 1 tablespoon of Bayou City all-purpose seasoning, garlic pepper, onion powder, cayenne pepper, and salt and pepper to taste. Stir continuously until the sauce thickens slightly, about 3-5 minutes.
  4. Combine Ingredients: Slice or shred the cooked chicken thighs. In a large mixing bowl, combine the cooked rice, cooked broccoli florets, shredded chicken, sour cream, Boursin cheese, and cheddar cheese. Pour the creamy sauce over the mixture and fold gently until all ingredients are evenly coated.
  5. Assemble the Casserole: Preheat your oven to 350°F (175°C). Transfer the combined mixture into a greased casserole dish, spreading it evenly.
  6. Bake: Place the casserole dish in the preheated oven and bake for 25-30 minutes, or until the casserole is bubbly and the top is golden and slightly crisp.
  7. Rest and Serve: Remove the casserole from the oven and let it rest for 5-10 minutes before serving to allow the flavors to meld and the casserole to set.

Notes

  • Cook the broccoli and rice ahead of time to save preparation time.
  • Adjust cayenne pepper to your preferred level of spiciness.
  • Use mild or medium cheddar cheese based on your taste preference.
  • Boursin cheese adds a creamy garlic and herb flavor but can be substituted with cream cheese mixed with garlic powder and herbs if unavailable.
  • This casserole reheats well and is great for meal prep.
