Why You’ll Love This Recipe
This casserole is exactly what I want from an easy weeknight dinner: minimal effort, comforting flavors, and very little cleanup.
The five-minute prep time is probably my favorite part. Once everything is assembled, the oven does the rest of the work.
It’s also made with just four ingredients, which makes it especially handy when you don’t have much time—or don’t feel like making another trip to the grocery store.
And because everything cooks together in one baking dish, you end up with tender chicken and creamy, flavorful rice without having to manage several pots and pans.
For the Chicken & Rice Casserole
- Chicken Breasts – boneless, skinless chicken breasts make this casserole hearty and filling. They bake right in the dish, so there’s no need to cook the chicken separately first.
- Long-Grain White Rice – use uncooked long-grain white rice here. It cooks right in the casserole and absorbs all those creamy, savory flavors as it bakes.
- Dry Onion Soup Mix – this is the little shortcut that brings a lot of flavor to the casserole. It seasons the rice and chicken without needing a long list of spices.
- Condensed Cream of Mushroom Soup – this is what gives the casserole that creamy, comforting texture and adds plenty of savory mushroom flavor.
- Water – mixed with the condensed soup, the water provides the moisture the uncooked rice needs to become tender as the casserole bakes.
Step-by-Step Instructions
Get the oven ready
Start by preheating the oven to 325°F (163°C). Then prepare a 9×13-inch baking dish with cooking spray.
Add the chicken
Season the chicken breasts with salt and pepper and place them in the prepared baking dish.
Layer in the rice
Sprinkle the uncooked rice evenly over the chicken, followed by the dry onion soup mix. There’s something wonderfully simple about this part—you’re really just layering everything together and letting the oven do the work.
Add the creamy mixture
Mix the condensed cream of mushroom soup with 1 ½ cups of water, then pour it evenly over the chicken and rice.
Cover and bake
Cover the dish tightly with foil and bake for 1 hour 15 minutes, or until the rice is tender and the chicken is fully cooked.
Serve
Once everything is cooked through, serve it warm and enjoy. This is comfort food at its easiest.
Expert Tips
The biggest secret to this casserole is really just giving it enough time to cook properly.
Cover the baking dish tightly with foil. Keeping the dish covered helps create the moisture the rice needs as it cooks.
Spread the rice evenly. This helps everything cook more consistently and prevents some areas from being more crowded than others.
Give the rice a little extra time if needed. Cooking times can vary between ovens and baking dishes. If the rice isn’t quite tender, continue baking for an additional 15–25 minutes as needed, just as noted in the recipe card.
And remember that the casserole is meant to be easy. There’s no need to fuss over it while it’s in the oven—that’s the beauty of a good dump-and-bake dinner.
Recipe Variations
One of the nice things about such a simple casserole is that you can change the flavor when you’re in the mood for something a little different.
For a slightly different creamy flavor, try cream of chicken soup in place of the cream of mushroom soup.
If you love mushrooms, sliced mushrooms make a cozy addition and work especially well with the creamy sauce.
You can also keep the casserole exactly as it is and change up what you serve alongside it. A simple roasted vegetable or fresh salad can make the meal feel completely different without changing the recipe itself.
Storage & Reheating
If you have leftovers, let the casserole cool and store it in an airtight container in the refrigerator.
When you’re ready to enjoy it again, reheat individual portions until heated through. Covering the portion while reheating can help keep the chicken and rice from drying out.
This casserole is especially nice to have waiting in the fridge for an easy lunch or another quick dinner later in the week.
What to Serve with Chicken & Rice Casserole
Because the chicken and rice are already hearty and comforting, I like to keep the sides simple.
A fresh green salad adds something crisp and refreshing alongside the creamy casserole. Roasted vegetables are another easy choice, especially when you want to turn dinner into a complete meal without adding much extra work.
You could also serve it with steamed vegetables for an especially simple weeknight dinner.
However you serve it, this is one of those meals that doesn’t need much alongside it. The casserole is warm, filling, and satisfying all on its own.

5 Common Questions
Can I use uncooked rice?
Yes! That’s exactly what this recipe calls for. The long-grain white rice goes into the baking dish uncooked, then cooks right alongside the chicken as it bakes.
The important thing here is to use the rice and liquid amounts in the recipe as written. The rice needs that moisture to cook properly, so this isn’t the time to eyeball things!
How do I know when the chicken is done?
The easiest way is to check the thickest part of the chicken breast with an instant-read thermometer. It should reach 165°F (74°C).
I always recommend checking rather than relying only on the cooking time, because chicken breasts can vary quite a bit in size. And of course, you want the rice tender too!
Why do I need to cover the casserole with foil?
Don’t skip the foil! It helps trap the steam inside the baking dish, which is what helps the uncooked rice become tender.
Think of the foil as part of the cooking process, not just something you put on top. If the dish isn’t covered tightly, you can lose too much moisture and end up with rice that hasn’t cooked properly.
What if my rice is still crunchy?
Easy fix—just give it more time.
Cooking times can vary depending on your oven, your baking dish, and even how tightly the foil is sealed. If the rice isn’t tender after the initial 1 hour 15 minutes, cover it again and continue baking for 15–25 minutes, checking as you go.
This is actually noted right on the recipe card, so don’t panic if yours needs a little longer!
How do I store and reheat leftovers?
If you have leftovers, lucky you! This is one of those dinners that makes an easy lunch the next day.
Store the casserole in an airtight container in the refrigerator and reheat portions until they’re hot throughout. Covering the portion while reheating can help keep the rice from drying out.
And as always with cooked leftovers, refrigerate them promptly and use them within 3–4 days for the best quality and food safety. The USDA also recommends reheating leftovers to 165°F (74°C).
