Easy Cheesy Chicken Broccoli Rice Casserole One Pot Oven
This is the kind of weeknight dinner you keep on repeat: hearty, cheesy, and made in one pot. It’s creamy, packed with tender chicken and broccoli, and finished in the oven so the top gets bubbly and golden. Everything cooks together, so cleanup is a breeze.
If you like meals that feel cozy but don’t take all night, this one’s for you.
Why This Recipe Works
- One pot convenience: You cook the rice, chicken, and broccoli in the same oven-safe pot, then slide it right into the oven to melt the cheese.
- Balanced and satisfying: Protein, veggies, and carbs all in one pan. No need for extra sides unless you want them.
- Foolproof texture: The rice simmers in seasoned broth for flavor, while the oven finish keeps it from getting mushy.
- Customizable: Swap cheeses, use different veggies, or switch the seasoning. It’s flexible and forgiving.
What You’ll Need
- 2 tablespoons olive oil or butter
- 1 pound boneless, skinless chicken breasts, cut into small bite-size pieces
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 cup long-grain white rice (uncooked; not instant)
- 2 cups low-sodium chicken broth
- 1 cup milk (whole or 2% for creaminess)
- 2 cups broccoli florets (fresh or thawed frozen, chopped small)
- 2 cups shredded cheese (sharp cheddar is classic; Monterey Jack or a blend works)
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 1/2 teaspoon paprika (optional, for color and warmth)
- 1/2 teaspoon dried thyme or Italian seasoning
- 1/4 cup grated Parmesan (optional, for extra savoriness)
- Cooking spray (if your pot isn’t well-seasoned or nonstick)
How to Make It
- Preheat and prep: Heat the oven to 375°F (190°C).If your Dutch oven or deep oven-safe skillet isn’t nonstick, lightly spray it.
- Brown the chicken: Warm the olive oil or butter over medium-high heat. Season the chicken with a pinch of salt and pepper, then sear for 3–4 minutes, just until lightly golden. It doesn’t need to be cooked through.Transfer to a plate.
- Soften aromatics: Add the onion to the pot with a small splash of oil if needed. Cook 2–3 minutes until translucent. Stir in the garlic for 30 seconds.
- Toast the rice: Add the rice, paprika, and thyme.Stir for 1 minute to coat the grains. This boosts flavor and helps the rice cook evenly.
- Add liquids: Pour in the chicken broth and milk. Stir, scraping up any browned bits from the bottom.Season with the remaining salt and pepper.
- Simmer: Return the chicken (and any juices) to the pot. Bring to a gentle simmer, then reduce the heat to medium-low. Cover and cook for 10 minutes, stirring once halfway to prevent sticking.
- Add broccoli: Stir in the broccoli florets and 1 cup of the shredded cheese.If using Parmesan, add it now. Taste and adjust seasoning.
- Oven finish: Smooth the top, sprinkle on the remaining 1 cup shredded cheese, and transfer the uncovered pot to the oven. Bake 12–15 minutes, until the rice is tender and the top is melted and bubbly with light golden spots.
- Rest and serve: Let the casserole sit 5 minutes before serving so it sets and thickens slightly.Scoop and enjoy.
How to Store
- Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
- Freeze: Portion into freezer-safe containers and freeze up to 2 months. Thaw in the fridge overnight.
- Reheat: Warm in a 325°F (165°C) oven, covered, for 15–20 minutes, or microwave in short bursts with a splash of broth or milk to keep it creamy.
Benefits of This Recipe
- Budget-friendly: Uses pantry staples and common ingredients.
- Kid-approved flavors: Cheesy and mild, with a gentle seasoning profile.
- Balanced meal: Protein, veggies, and grains in one dish.
- Make-ahead friendly: Assembles easily and reheats well.
Pitfalls to Watch Out For
- Using instant rice: It cooks too quickly and can turn mushy. Stick with long-grain white rice.
- Overcooking the chicken upfront: Just sear it.It finishes cooking with the rice and in the oven.
- Too high a simmer: Rice can scorch. Keep it gentle and stir once during the 10-minute simmer.
- Large broccoli florets: Cut them small so they turn tender in the oven window.
Recipe Variations
- Swap the protein: Use rotisserie chicken (stir in at Step 7), turkey, or cooked sausage.
- Go extra creamy: Replace half the milk with half-and-half or stir in 2 ounces cream cheese in Step 7.
- Add crunch: Top with buttered panko or crushed Ritz before baking.
- Veggie boost: Fold in peas, diced carrots, or spinach with the broccoli.
- Different cheeses: Try Gruyère for depth, pepper jack for heat, or a cheddar–mozzarella blend for extra melt.
- Brown rice version: Par-cook brown rice separately until nearly tender, then proceed from Step 7.
FAQ
Can I use frozen broccoli?
Yes. Thaw it and pat it dry so excess moisture doesn’t water down the casserole. Add it at the same step as fresh.
What if I don’t have an oven-safe pot?
Cook through Step 7 in a regular pot, then transfer the mixture to a greased 9×13-inch baking dish. Top with cheese and bake as directed.
Can I make it dairy-free?
Use a creamy unsweetened plant milk, dairy-free cheese that melts well, and a splash of extra broth if needed. Taste and adjust seasoning since dairy-free cheeses vary in saltiness.
How do I prevent the rice from sticking?
Keep the simmer gentle, stir once during the covered cook, and scrape the bottom well before adding liquids. A heavy-bottomed pot helps.
Is it spicy?
No. It’s mild as written. If you want heat, add red pepper flakes or use pepper jack cheese.
Can I use leftover cooked rice?
Yes. Skip the simmer. Stir 3 to 3 1/2 cups cooked rice into the saucy chicken-onion mixture with broccoli, add cheese, and bake until hot and bubbly.
