Gluten-Free Chicken and Rice Casserole

Chicken and rice casserole is the kind of weeknight dinner that comes together quickly if you start with cooked chicken — rotisserie works perfectly here — and day-old rice. Everything goes into one baking dish, topped with cheddar, and baked until bubbling. It’s straightforward comfort food that reheats well and scales up easily for larger groups.

The one ingredient that needs attention in a gluten-free version is the cream of mushroom soup. Many canned versions contain wheat flour as a thickener — look for one labeled gluten-free, or make a quick substitute with butter, gluten-free flour, broth, and a splash of cream.

Ingredients

• 2 cups cooked white rice (jasmine or basmati both work well — day-old rice holds up better than freshly cooked)
• 3 cups cooked, shredded chicken breast (rotisserie chicken saves time)
• 1 can (10.5 oz) gluten-free cream of mushroom soup
• 1 cup gluten-free chicken broth
• 1 cup shredded cheddar cheese
• ½ cup onion, finely chopped
• ½ cup celery, chopped
• ½ cup carrots, finely diced
• 2 cloves garlic, minced
• 1 teaspoon dried thyme
• 1 teaspoon dried parsley
• 2 tablespoons olive oil
• Salt and pepper to taste
• Optional: ½ cup gluten-free breadcrumbs, tossed in a little olive oil, for a crunchy topping

Instructions

Step 1 — Preheat Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.

Step 2 — Sauté the vegetables Heat olive oil in a skillet over medium heat. Add onion, celery, carrots, and garlic. Cook for 5–7 minutes, stirring occasionally, until softened and fragrant.

Step 3 — Combine In a large bowl, combine the cooked rice, shredded chicken, sautéed vegetables, cream of mushroom soup, chicken broth, thyme, parsley, salt, and pepper. Stir until evenly mixed — don’t overmix or the rice will break down.

Step 4 — Transfer to baking dish Pour the mixture into the prepared baking dish and spread into an even layer with a spatula.

Step 5 — Add topping Scatter shredded cheddar evenly over the top. If using breadcrumbs, sprinkle them over the cheese.

Step 6 — Bake Bake uncovered for 25–30 minutes until the top is golden and the casserole is bubbling at the edges. The internal temperature should reach 165°F (74°C). If the cheese starts to brown too quickly, tent loosely with foil.

Step 7 — Rest and serve Let the casserole rest for 5–10 minutes before serving — this helps it firm up and makes it easier to portion.

Tips

• Day-old rice works better than freshly cooked — fresh rice can make the casserole slightly mushy as it absorbs more liquid during baking
• If you don’t have gluten-free cream of mushroom soup, substitute with a quick homemade version: melt 2 tablespoons butter, whisk in 2 tablespoons gluten-free flour, then gradually add 1 cup broth and ½ cup cream until thickened
• Freshly grated cheddar melts more smoothly than pre-shredded, which often contains anti-caking starch
• Use low-sodium broth to control the salt level — cream of mushroom soup already adds a fair amount

Variations

• Add broccoli: Fold in 2 cups of small broccoli florets with the other vegetables
• Wild rice: Substitute wild rice for white rice — extend bake time by about 10 minutes
• Cream cheese: Stir in 4 oz softened cream cheese for an extra creamy texture
• Spicy: Add diced green chiles and swap cheddar for Monterey Jack
• Dairy-free: Use cashew cream in place of the soup and a vegan cheese alternative
• Raw chicken: If starting with raw chicken instead of cooked, cut into small pieces and extend the bake time by about 10 minutes, ensuring it reaches 165°F throughout

Storage

• Refrigerator: up to 4 days in an airtight container
• Freezer: portion into individual servings, wrap in foil, and freeze for up to 3 months
• Reheat in the oven at 350°F covered with foil, adding a splash of broth if the rice looks dry, or in the microwave covered with a damp paper towel

Frequently Asked Questions

Why is my casserole dry? The most common cause is not enough liquid. Make sure you’re using the full cup of broth alongside the soup. If it looks dry before baking, add an extra splash of broth. Covering with foil for the first 15 minutes of baking also helps retain moisture.

Why did my casserole turn out mushy? Overmixing can break down the rice, and freshly cooked rice absorbs too much liquid. Use day-old rice and stir gently just until everything is combined.

Can I make this in a slow cooker? Yes. Combine all ingredients in the slow cooker and cook on low for 4 hours. Add the cheese in the last 30 minutes. The topping won’t get crispy in the slow cooker, but the casserole itself will be just as flavorful.

How do I make this dairy-free? Use a dairy-free cream of mushroom soup or homemade version with plant-based milk, skip the cheddar or use a vegan alternative, and use olive oil instead of butter.

Can I use rotisserie chicken? Yes — it’s actually the most practical option for this recipe. Strip the meat from a store-bought rotisserie chicken and shred it. Just check that the seasoning on the rotisserie chicken is gluten-free if that’s a concern.
