This satisfying casserole combines diced chicken breast with uncooked long-grain rice in a velvety sauce made from cream of chicken soup, sour cream, and broth. The mixture bakes covered for tender, fluffy rice, then gets topped with extra cheddar for a golden, bubbly finish. Peas and carrots add color and nutrition while thyme and paprika provide subtle depth. Perfect for meal prep or feeding a crowd, this dish comes together quickly and bakes hands-free in the oven.
The house was freezing that first winter in our drafty rental, and I needed something that would warm us from the inside out. I threw together whatever I had in the fridge—some leftover chicken, rice, cheese—and thirty minutes later, the kitchen smelled like heaven. My roommate walked in, took a deep breath, and asked if we could have this every Tuesday. That was ten years ago, and Tuesdays still smell like bubbly cheese and comfort.
Last winter my sister called me at midnight, crying over a breakup and hungry. I talked her through this recipe over the phone, pacing my kitchen while she measured ingredients in hers. Two days later she texted me a photo of an empty baking dish and said she felt like she could handle life again. Sometimes cheese and carbs are genuinely therapeutic.
Ingredients
- 2 cups cooked chicken breast: Rotisserie chicken works beautifully here and saves so much time on busy weeknights
- 1 cup long-grain white rice, uncooked: Long-grain stays fluffy and separate while baking, never mushy like shorter varieties
- 1 medium onion, finely chopped: The foundation of flavor—sautéing it first removes any harsh bite and adds sweetness
- 2 cloves garlic, minced: Fresh garlic makes all the difference, though jarred works in a pinch
- 1 cup frozen peas and carrots: Thaw them first so they do not water down your sauce as everything bakes
- 1 cup sour cream: This creates that velvety texture and tangy creaminess we all crave
- 1 ½ cups shredded cheddar cheese, divided: Sharp cheddar gives the best flavor punch, though medium works if that is what you have
- ½ cup mozzarella cheese, shredded: The secret to that gorgeous cheese pull in every serving
- 1 can condensed cream of chicken soup: The backbone of the sauce—do not substitute with the low-fat version, it affects texture
- 2 ½ cups low-sodium chicken broth: Low-sodium lets you control the salt level since the cheese and soup add plenty
- 2 tbsp unsalted butter: For sautéing the aromatics and greasing the pan
- ½ tsp salt, black pepper, and paprika: The essential trio that brings everything together
- ½ tsp dried thyme: Optional, but it adds an earthy note that makes the dish taste restaurant-quality
Instructions
- Get your oven ready:
- Preheat to 375°F and butter a 9x13 baking dish thoroughly, getting into all the corners so nothing sticks.
- Build your flavor base:
- Melt butter in a skillet over medium heat and cook the onion and garlic until they are soft and translucent, about 3 minutes.
- Bring it all together:
- In a large bowl, combine the cooked onion and garlic with everything except the remaining ½ cup of cheddar—chicken, uncooked rice, soup, sour cream, broth, vegetables, 1 cup cheddar, mozzarella, and all those spices.
- Assembly time:
- Pour the mixture into your prepared dish and spread it evenly so the rice cooks uniformly throughout.
- The covered bake:
- Cover tightly with foil—no gaps allowed—and bake for 30 minutes so the rice can absorb all the liquid and cook through.
- The golden finish:
- Remove the foil, sprinkle that remaining ½ cup cheddar across the top, and bake uncovered for 8 to 10 more minutes until everything is bubbling and that cheese is perfectly melted.
- The hardest part:
- Let it stand for 5 minutes before serving—this helps the casserole set so you get neat scoops instead of a sloppy mess.
This recipe became my go-to the year I lived with three roommates and we all had different schedules. I would assemble it in the afternoon, and whoever got home first just popped it in the oven. Some of my favorite memories happened around that baking dish, forks in hand, talking about our days while the cheese still stretched between our plates.
Make It Your Own
Brown rice works if you want more fiber, but you will need to add about ½ cup more broth and bake for an extra 10 to 15 minutes. I have learned this the hard way by serving slightly crunchy rice to dinner guests who were too polite to complain. Just check the rice before that final cheese broil and cover it back up if it needs more time.
Serving Suggestions
A crisp green salad with vinaigrette cuts through all that richness beautifully. I like to serve this with roasted broccoli or green beans when I want something substantial. A glass of Chardonnay does not hurt either, though milk works perfectly fine for the kids.
Storage And Leftovers
This keeps in the refrigerator for up to four days and freezes beautifully for up to three months if you wrap it tightly. I often make two at once and freeze one unbaked—that dinner rush on Thursday nights feels like a gift from my past self.
- Thaw frozen casseroles overnight in the fridge before baking
- Add 10 minutes to the covered baking time if baking from refrigerated
- Reheat individual portions in the microwave with a splash of broth to bring back the creaminess
Some recipes are just dinner, but this one feels like a hug on a plate. I hope it finds its way into your regular rotation and creates its own memories around your table.
Recipe FAQs
- → Can I use brown rice instead of white?
-
Yes, brown rice works well but will need additional cooking liquid and about 15-20 minutes longer baking time. Check that the rice is tender before removing from the oven.
- → Can I make this ahead of time?
-
Absolutely. Assemble the casserole up to 24 hours in advance, cover tightly, and refrigerate. When ready to bake, you may need a few extra minutes since it will be cold.
- → What type of chicken works best?
-
Rotisserie chicken adds excellent flavor and saves time. Alternatively, poach or bake chicken breasts specifically for this dish. Leftover cooked chicken also works perfectly.
- → Can I freeze this casserole?
-
Yes, freeze before baking for up to 3 months. Thaw overnight in the refrigerator, then bake as directed. Alternatively, freeze leftovers in individual portions for quick meals.
- → How do I know when it's done baking?
-
The rice should be tender and have absorbed most of the liquid. The cheese should be melted and lightly browned, and the entire casserole should be bubbling around the edges.
- → Can I add other vegetables?
-
Certainly. Try adding broccoli florets, diced bell peppers, corn, or green beans. Add heartier vegetables like broccoli during the initial bake, while delicate ones like spinach can be stirred in before serving.
