Top Reasons To Make It

• It’s a true one-pan wonder, meaning fewer dishes to wash after you’ve enjoyed your meal.
• This recipe is a fantastic way to use up leftover or rotisserie chicken, making it one of my go-to shredded chicken recipes.
• The creamy rice and tender chicken are perfectly balanced by that savory, crunchy onion topping. So good.
• It’s wonderfully adaptable. I’ll share some easy variations later so you can make it your own.
• It freezes beautifully, giving you a ready-made healthy dinner idea for a future busy day.

Ingredients

• 2 cups cooked chicken, shredded or diced: Using rotisserie chicken makes this one of the quickest quick dinner ideas.
• 1 cup long-grain white rice, uncooked: The base of our cozy casserole.
• 1 (10.5 oz) can cream of mushroom soup: Creates a rich, creamy sauce without any fuss.
• 1 cup chicken broth: Thins the soup to the perfect consistency for cooking the rice.
• 1 cup milk (whole or 2%): Adds extra creaminess and richness.
• 1 cup frozen mixed vegetables (peas, carrots, corn): For a pop of color and nutrition, a staple in healthy dinner recipes.
• 1 teaspoon garlic powder: For a warm, savory depth.
• 1/2 teaspoon onion powder: Enhances the overall savory flavor.
• 1/2 teaspoon black pepper: A little kick of warmth.
• 1 (6 oz) can French-fried onions: For that irresistible crispy onion topping we all love.

Instructions

1. First, preheat your oven to 350°F (175°C) and grab a 9×13 inch baking dish. There’s no need to grease it.
2. In a large mixing bowl, combine the uncooked rice, cream of mushroom soup, chicken broth, milk, frozen vegetables, garlic powder, onion powder, and black pepper. Give it a good stir until everything is well combined.
3. Gently fold in the cooked chicken until it’s evenly distributed throughout the mixture.
4. Pour the entire mixture into your baking dish and spread it out into an even layer.
5. Cover the dish tightly with aluminum foil and bake for 50 minutes.
6. After 50 minutes, carefully remove the dish from the oven and take off the foil. The rice should be tender and have absorbed most of the liquid.
7. Sprinkle the French-fried onions evenly over the top. Return the dish to the oven, uncovered, and bake for another 10-15 minutes, or until the onions are golden brown and crispy.
8. Let the casserole sit for about 5 minutes before serving. This helps it set up perfectly.

Variations & Substitutions

• For a veggie boost: Swap the mixed vegetables for chopped broccoli florets or fresh spinach.
• Dairy-free? Use a creamy soup alternative and unsweetened almond or oat milk.
• Want a different protein? Diced smoked turkey sausage is a delicious swap for the chicken.
• Creamier version: Stir in a 1/2 cup of sour cream or plain Greek yogurt with the soup mixture for an extra rich and creamy chicken recipe.
• Gluten-free: Use a certified gluten-free cream of mushroom soup and check that your fried onions are gluten-free.

Serving Ideas & Pairings

This casserole is a complete meal all on its own, but a simple side can round things out beautifully. I love serving it with a crisp green salad with a bright vinaigrette to contrast the richness. Buttermilk biscuits or a slice of crusty bread are also wonderful for soaking up every last bit of the creamy sauce. For a lighter pairing, some steamed green beans or roasted asparagus are always a hit.

Storage & Reheating

Let the casserole cool completely before storing. It will keep in an airtight container in the refrigerator for up to 4 days. To freeze, portion it into freezer-safe containers for up to 3 months. Thaw overnight in the fridge before reheating. The best way to reheat it is in the oven at 350°F until warmed through, which helps maintain the texture of the rice. You can also reheat single portions in the microwave, covered, stirring halfway through. Just note that the onion topping will soften—still tasty, but not as crispy.

Pro Tips For Success

• Don’t skip the step of letting the casserole rest after baking. It makes all the difference in getting perfect, non-mushy slices.
• If you’re using freshly cooked chicken, make sure it’s not piping hot when you add it to the mix; room temp is best.
• For an even crispier top, you can add an extra handful of fried onions in the last 5 minutes of baking.
• Honestly, if you’re short on time, you can use instant rice. Just reduce the initial covered baking time to about 25-30 minutes.
• Give the mixture a good stir before adding the topping to ensure the rice is evenly distributed.

Frequently Asked Questions

• Can I use brown rice instead of white rice? You can, but it will require more liquid and a longer baking time. I’d suggest using 1 1/2 cups of broth and baking covered for about 1 hour and 15 minutes before adding the topping.
• My casserole is still a bit liquidy after baking. What happened? This usually means the rice needed a little more time. Just pop it back in the oven, covered, for another 10-15 minutes until the rice is tender and the liquid is absorbed.
• Can I assemble this casserole ahead of time? Absolutely! Assemble it without the onion topping, cover, and refrigerate for up to 24 hours. When you’re ready, bake as directed, adding a few extra minutes to the covered baking time since it’s going in cold.
• What are some other easy meals I can make with rotisserie chicken? Rotisserie chicken is a lifesaver! You can use it for quick chicken salad, enchiladas, soups, or simply served with a side of roasted vegetables for a super fast healthy dinner idea.
