Step-by-Step Chicken and Rice Casserole Instructions

First things first, let’s get our ingredients prepped and measure. You can use fresh broccoli if you prefer, but I typically use frozen here. We are going to dice one onion, bell pepper, and jalapeño (optional), and then grate our cheese. I also typically grab a Rotisserie chicken for this sort of thing, because they’re the best bang for your buck in this economy, lol.

Step 1: Prepare the Yellow Rice and Chicken

For the rotisserie chicken, we are going to remove the bone, skin, and cartilage. Once you’ve removed everything that could send you to the dentist, chop up the chicken into bite-sized pieces.

If you find yourself with some leftover chicken from a BBQ or roasted chicken dinner, etc…. This is a great way to repurpose that ingredient too.

Yellow Rice

If you don’t already have cooked yellow rice, here’s how to make it from scratch: Rinse 2½ cups long-grain rice until the water runs clear.

In a medium pot, sauté ½ diced onion and ½ diced red bell pepper in 1 tbsp oil over medium heat for 3–4 minutes.

Stir in the minced jalapeño (optional) and 1 tbsp minced garlic; cook 30–45 seconds until fragrant. Add the rice, toasting lightly for 1–2 minutes.

Mix in ½ packet Sazón, 1 tsp chicken base, 4½ cups water (or 4 cups water + ½ cup chicken broth), and a pinch of AP seasoning.

Bring to a boil, then reduce to low. Cover and simmer 15–18 minutes until tender. Fluff with a fork and set aside.

Step 2: Build the Creamy Cheese Sauce

Preheat your oven to 375°F (190°C).

In a large skillet or Dutch oven, heat 1 tbsp oil or butter over medium heat. Add the remaining onion and red bell pepper; cook 3–4 minutes until softened.

Sprinkle in Italian seasoning and a pinch of AP seasoning. Add the garlic and cook 30–45 seconds.

Stir in 2–3 tbsp flour to create a light roux, cooking 1–2 minutes. Slowly whisk in 1 cup warm chicken broth until smooth, then pour in 2 cups heavy cream.

Simmer for 3–5 minutes until the sauce thickens.

Reduce the heat to low and stir in 1½ cups Colby-Jack and ¾ cup Parmesan cheese, reserving the rest for topping.

Taste and adjust seasoning — a little extra Sazón goes a long way for color and depth.

Step 3: Assemble the Casserole

Stir in 4 cups of diced cooked chicken and 2 cups of broccoli florets into the sauce.

Fold in the cooked yellow rice until evenly coated.

Transfer mixture to a greased 9×13 baking dish. Sprinkle the remaining ½ cup Colby-Jack and ¼ cup Parmesan evenly on top.

Step 4: Bake It to Perfection

Bake uncovered at 375°F for 20–25 minutes, until the top is bubbly and golden.

For extra crispiness, broil for 1–2 minutes (watch closely!).

Let rest for 5 minutes, then top with ¼ cup diced parsley before serving.

Step 5: Serve & Enjoy

Scoop generous portions and top with cracked black pepper or a dash of hot sauce. I love pairing it with a crisp salad or buttery cornbread to balance the richness.

Make-Ahead, Reheating & Freezing Tips

• Refrigerate: Cool completely, cover tightly, and store up to 4 days.
• Freeze: Portion into containers and freeze for up to 3 months.
• Reheat: In the oven at 325°F or microwave until hot. If dry, stir in a splash of cream or chicken broth to refresh.

Why This Recipe Works

This casserole nails the trifecta of comfort: flavorful rice, tender chicken, and a creamy, cheesy sauce that ties it all together. The Sazón adds that signature golden hue and savory depth, while Italian seasoning and Parmesan bring a familiar warmth. Best of all, it’s flexible — use what’s on hand, adjust the heat, and scale it up for guests.
