Ingredients for Old-Fashioned Chicken and Rice Casserole

• 1.5 cups long-grain rice – forms a fluffy base and soaks up the flavorful sauce as it cooks.
• 1.5 pounds boneless skinless chicken thighs – juicy, forgiving, and perfect for slow cooking with the rice.
• 1 medium onion, diced – builds sweet, savory depth into the sauce.
• 2 cloves garlic, minced – adds a bright, aromatic kick.
• 2 cups chicken broth – the cooking liquid that steams and flavors everything together.
• 1 cup milk – creamy base that lightens the sauce and helps emulsify the soup.
• 1 can cream of mushroom soup (10.5 oz) – classic casserole binder for a lush, velvety texture.
• 1 cup shredded cheddar cheese – melty richness on top, with a savory finish.
• 2 tablespoons butter – adds a touch of richness and a silky mouthfeel.
• 0.5 teaspoon dried thyme – a gentle herby note that complements the chicken.
• 0.5 teaspoon salt, plus more to taste – essential seasoning to bring all flavors forward.
• 0.25 teaspoon black pepper – a subtle bite that balances the creamy sauce.
• 1 cup frozen peas – bursts of color and sweetness that brighten the dish.
• 1 tablespoon olive oil (optional, for browning) – helps you brown the chicken without sticking.
• 1 medium carrot, finely chopped (optional) – adds a hint of sweetness and color.

Step-by-Step Guide to Making Old-Fashioned Chicken and Rice Casserole

1. Preheat your oven to 375°F (190°C). This ensures a steady bake and a gentle finish.
2. In a large skillet, melt the butter over medium heat. Add the onion and carrot (if using) and sauté until the onion is translucent and the carrot softens, about 4–5 minutes. This builds a foundation of sweetness and depth.
3. Add the garlic and cook for an additional 30 seconds, just until fragrant. Then push the vegetables aside, add the chicken thighs, and lightly brown them on both sides. They don’t need to be fully cooked through; you’re building flavor here.
4. Stir in the cream of mushroom soup, milk, chicken broth, thyme, salt, and pepper. Bring the mixture to a gentle simmer, then add the frozen peas and half of the cheddar cheese. Stir until the sauce is smooth and slightly thickened. This is your creamy, comforting sauce that will cling to the rice.
5. Rinse the rice briefly under cold water to remove excess starch. Scatter the raw rice evenly in a large casserole dish. Pour the hot sauce over the rice, then nestle the chicken thighs on top. The liquid should come about halfway up the sides of the chicken; if not, add a splash more broth.
6. Cover the dish tightly with a lid or foil and bake for 40–45 minutes, until the rice is tender and the chicken reaches a safe internal temperature of 165°F (74°C). This long, gentle bake ensures the flavors meld and the textures harmonize.
7. Remove the cover for the last 5–10 minutes and sprinkle the remaining cheddar on top to melt and lightly brown. This creates a glossy, cheesy finish without the need for extra steps.
8. Let the casserole rest for about 10 minutes before serving. Resting helps the sauce thicken a touch and makes scooping easier.
9. If you love a crisper top, you can switch to a quick broil for 1–2 minutes at the end, watching carefully to prevent burning.

Frequently Asked Questions

Can I use white rice instead of long-grain rice?

Yes, but be mindful that white rice can cook faster. If you switch to white rice, check for doneness around the 35-minute mark and add a little extra liquid if needed to prevent drying out.

What if I don’t have cream of mushroom soup?

You can make a quick cream substitute: whisk together 1/2 cup cream or milk with 1 tablespoon flour, then whisk in 1/2 cup chicken broth to replace the canned soup. Add 1/2 teaspoon additional salt to compensate for the missing salt in the can.

Can I freeze leftovers?

Leftovers freeze well. Cool completely, portion into airtight containers, and freeze for up to 2–3 months. Thaw overnight in the fridge and reheat gently on the stove or in the oven until warmed through.

• 1 cup frozen peas
• 1 tablespoon olive oil (optional, for browning)
• 1 medium carrot, finely chopped (optional)

Instructions

 

• Preheat your oven to 375°F (190°C). If you want a crisp top, plan to finish with a quick under-broiler step, but it isn't necessary.
• In a large skillet, melt the butter over medium heat. Add the diced onion and carrot (if using) and sauté until the onion becomes translucent and the carrot softens, about 4–5 minutes.
• Add the garlic and cook for another 30 seconds, until fragrant. Push the vegetables to the side, add the chicken thighs, and lightly brown them on both sides. They don’t need to be fully cooked through at this stage; you’re building flavor.
• Stir in the cream of mushroom soup, milk, chicken broth, thyme, salt, and pepper. Bring the mixture to a gentle simmer, then add the frozen peas and half of the cheddar cheese. Stir until the sauce is smooth and slightly thickened.

• Let the casserole rest for about 10 minutes before serving. This helps the flavors meld and makes scooping easier.
• If you like a crisper top or a richer finish, you can switch to a quick broil for 1–2 minutes at the end, watching carefully so it doesn’t burn.
