Ingredients
- 2 cups cooked chicken, shredded or cubed (rotisserie works great)
- 2 cups broccoli florets, chopped small
- 1 cup long-grain white rice, uncooked
- 2 cups chicken broth
- 1 cup whole milk
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 2 ½ cups shredded sharp cheddar cheese, divided
- ½ teaspoon dried thyme
- ½ teaspoon garlic powder
- ¼ teaspoon salt (or to taste)
- ¼ teaspoon black pepper
- ½ cup diced yellow onion
Ingredient Notes
- Cooked Chicken: For ultimate convenience, use a store-bought rotisserie chicken. Leftover grilled or baked chicken also works beautifully. If starting from raw, poach two large chicken breasts.
- Rice: This recipe uses standard long-grain white rice. If you wish to use brown rice, you will need to pre-cook it, as the baking time is insufficient for raw brown rice. Leftover rice is also excellent here.
- Cheese: Sharp or extra-sharp cheddar provides the best, most nostalgic flavor. Grating your own cheese will result in a much smoother melt, as pre-shredded cheese often contains anti-caking agents that hinder melting.
- Broccoli: Fresh broccoli florets give the best texture. If using frozen broccoli, thaw it completely and squeeze out any excess moisture to prevent a watery casserole.
- Dairy-Free: To make this dairy-free, substitute the butter with olive oil, the milk with an unsweetened plain dairy-free milk (like oat or almond), and use a high-quality dairy-free cheddar alternative that is known to melt well.
- Gluten-Free: Swap the all-purpose flour for a 1-to-1 gluten-free baking flour blend. Most other ingredients are naturally gluten-free.
How to Make This Recipe
- Preheat and Prep: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish (like the rustic ceramic one seen in the hero image) with butter or cooking spray.
- Sauté Aromatics: In a medium saucepan, melt the butter over medium heat. Add the diced yellow onion and sauté until softened and translucent, about 5 minutes. Add the minced garlic (if using) and cook for another 60 seconds until fragrant.
- Make the Roux: Sprinkle the flour over the onion mixture. Stir constantly for 1-2 minutes to cook out the raw flour taste; the mixture will paste slightly.
- Create the Sauce: Slowly whisk in the chicken broth, making sure no lumps form. Once smooth, whisk in the whole milk, dried thyme, garlic powder, salt, and black pepper. Bring the mixture to a gentle simmer, stirring occasionally, until it slightly thickens, about 5-7 minutes.
- Add Cheese: Remove the saucepan from the heat. Immediately stir in 1 ½ cups of the shredded cheddar cheese, stirring until completely melted and smooth.
- Assemble the Casserole: In your prepared 9×13 baking dish, combine the uncooked white rice, small broccoli florets, and the cooked cubed chicken.
- Combine and Top: Pour the creamy cheese sauce evenly over the rice, chicken, and broccoli mixture. Gently stir right in the dish to ensure everything is evenly coated and the rice isn’t clumped.
- Bake: Cover the baking dish tightly with aluminum foil. Bake for 25 minutes.
- Finish: Remove the foil. The rice should be mostly tender. Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top. Bake, uncovered, for an additional 10-15 minutes, until the cheese is bubbly and slightly golden on the edges, as seen in the images.
- Rest and Serve: Let the casserole rest for 5-10 minutes before serving. This crucial step allows the sauce to set slightly and the flavors to meld. Garnish with fresh parsley if desired.
Recipe Tips
- Size Matters for Broccoli: Chop your broccoli florets quite small. Since the casserole only bakes for a total of 35-40 minutes, large florets will remain too crunchy. Small pieces ensure everything cooks through evenly.
- Shred Your Own Cheese: As mentioned, pre-shredded cheese is coated in potato starch to keep it from clumping in the bag. This starch prevents the cheese from melting into a perfectly smooth sauce. For the creamiest result, buy a block and shred it yourself.
- Check Your Rice: Ensure you are using uncooked long-grain white rice. Do not use instant rice (which will turn to mush) or uncooked brown rice (which will not cook in the allotted time).
- Don’t Skip the Rest: Letting the casserole sit for 5-10 minutes after it comes out of the oven is essential. It lets the rice finish absorbing the liquid and helps the sauce thicken up for a perfect texture.
- Tightly Seal: When baking covered in step 8, make sure the aluminum foil seal is tight. This traps the steam necessary to cook the uncooked rice and broccoli properly.
- Add Extra Seasoning Later: Wait until the casserole is fully baked and rested to taste for seasoning. The chicken broth, rotisserie chicken, and cheese all contribute salt, so you may not need much additional seasoning at the start.
Variations
- Spicy Version: Add ½ teaspoon of red pepper flakes to the sauce along with the other spices, or stir in a diced jalapeño with the onions. Use Pepper Jack cheese instead of cheddar.
- Vegetarian Version: Replace the chicken with 1 ½ cups of cooked chickpeas or white beans, and use vegetable broth instead of chicken broth.
- Air Fryer Version: While you can’t make the whole casserole in the air fryer, you can air-fry the broccoli florets first (360°F for 5-7 mins) to get roasted, crispy edges before adding them to the bake for extra flavor.
- Lower-Carb (Cauliflower Rice) Version: Replace the uncooked white rice with 3 cups of steamed (and well-squeezed) cauliflower rice. Reduce the chicken broth to 1 cup, as cauliflower releases moisture. Adjust bake time as needed (likely 25-30 mins total).
- Curry Twist: Add 1 tablespoon of mild curry powder to the roux along with the flour for a delicious, cozy alternative flavor profile.
Storage
- Refrigerator: Allow the casserole to cool to room temperature. Cover the dish tightly with plastic wrap or aluminum foil, or transfer leftovers to an airtight container. Store in the refrigerator for 3 to 4 days.
- Freezer: This casserole freezes well before baking. Assemble the entire dish (using pre-cooked, cooled chicken and rice) in a freezer-safe container, but stop before adding the final cheese topping. Wrap tightly with plastic and foil. Freeze for up to 3 months. Thaw completely in the refrigerator before baking as directed (adding 10-15 minutes to the initial covered bake time). Freezing after baking is possible but can affect the texture of the broccoli and sauce upon reheating.
- Reheating: To reheat single portions, microwaving is fine. For larger portions, place the casserole back into a 350°F (175°C) oven, covered with foil, for 15-20 minutes until heated through. Add a splash of milk or broth if it seems dry.
Serving Suggestions
- Simple Green Salad: A crisp salad with a bright vinaigrette provides the perfect fresh contrast to the rich, cheesy casserole.
- Steamed Green Beans: For an easy, classic side dish.
- Roasted Carrots: The sweetness of roasted carrots complements the savory sharp cheddar flavor.
- Garlic Bread: Essential for soaking up any extra cheese sauce.
- Sliced Tomatoes: In late summer, simple slices of ripe tomatoes with sea salt are a perfect match.
- Creamy Tomato Soup: For an ultimate comfort food dinner.
- Dinner Rolls: Soft rolls are perfect for making mini-sandwiches with leftovers.
