This chicken and rice casserole transforms simple ingredients into a comforting meal that feels like a warm hug on a plate. It has become my go-to recipe when I need to feed a crowd or want leftovers that taste even better the next day.
My mother used to make this casserole every Sunday during the colder months. The aroma filling our home signaled family dinner time and always brought everyone to the table without having to call twice.
Ingredients
- Shredded chicken: provides lean protein and makes this dish hearty and filling. Use rotisserie chicken for convenience and extra flavor.
- Long grain white rice: creates the perfect fluffy base that absorbs all the savory flavors. Rinse it first for best texture.
- Chicken broth: infuses the rice with rich flavor as it cooks. Use low sodium if watching salt intake.
- Milk: adds creaminess without heavy cream. Whole milk works best but 2% is fine too.
- Cheddar cheese: creates that irresistible golden crust. Choose sharp cheddar for more pronounced flavor.
- Frozen peas: add sweet pops of color and nutrition. No need to thaw them first.
- Sliced carrots: provide natural sweetness and hearty texture. Cut them uniformly for even cooking.
- Onion and garlic: form the aromatic foundation. Fresh minced yields the best flavor profile.
- Butter: adds richness and helps create a velvety texture throughout the casserole.
- Herbs and seasonings: balance the richness with warmth and depth. Fresh thyme can substitute for dried at triple the amount.
Step-by-Step Instructions
- Prepare Your Baking Dish:
- Preheat your oven to 375°F and thoroughly grease a 9x13 inch baking dish making sure to get the corners. This prevents sticking and makes cleanup easier. A light coating of cooking spray works perfectly.
- Sauté The Aromatics:
- Heat butter in a skillet over medium heat until melted and slightly bubbling. Add diced onions and cook for about 4 minutes until they become translucent but not brown. Add minced garlic during the last 30 seconds to prevent burning. This foundational step builds deep flavor for the entire dish.
- Create The Base Mixture:
- In a large mixing bowl combine the uncooked rice chicken broth milk salt pepper and thyme. Stir well to ensure the seasonings are evenly distributed. The rice will absorb these flavors as it cooks creating a delicious foundation.
- Add Proteins And Vegetables:
- Gently fold in your cooked shredded chicken sliced carrots frozen peas and half of the shredded cheese. Use a rubber spatula to combine everything without breaking down the chicken too much. The mixture should look substantial but not dry.
- Assemble And Top:
- Pour the entire mixture into your prepared baking dish spreading it into an even layer. Sprinkle the remaining cheese evenly across the top focusing on good coverage at the edges where it will create delicious crispy bits.
- Bake Covered Then Uncovered:
- Cover the dish tightly with aluminum foil and bake for 45 minutes. This steam cooks the rice and vegetables perfectly. Then remove the foil and broil for 5 to 10 minutes watching carefully until the cheese forms a golden bubbly crust.
- Rest Before Serving:
- Allow the casserole to rest for 5 to 10 minutes before serving. This critical step allows the liquids to redistribute and the casserole to set up properly for serving. Garnish with fresh herbs just before bringing to the table.

The secret ingredient in this recipe is patience during that final resting period. My grandmother always insisted on the full 10 minutes which I used to find torturous as a child when the delicious aroma was filling the kitchen. Now I appreciate how much better the texture is when you give it that time to set.
Make It Your Own
This casserole welcomes personalization based on what your family enjoys or what you have in the pantry. Try adding a layer of crushed buttery crackers on top for extra crunch or mix in different cheese varieties like Monterey Jack or Gruyere for a flavor twist. Some of my friends add broccoli instead of peas or include diced bell peppers for color and sweetness.

Storage And Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors actually develop and improve overnight making this perfect for meal prep. When reheating individual portions add a tablespoon of water or broth before microwaving to restore moisture. For the whole casserole cover with foil and warm in a 325°F oven until heated through about 20 minutes.
Serving Suggestions
This casserole stands beautifully on its own as a complete meal but pairs wonderfully with a crisp green salad dressed simply with vinaigrette. For entertaining serve alongside warm crusty bread and a light vegetable side like steamed green beans or roasted asparagus. During holiday gatherings it makes an excellent side dish to complement roasted meats.
Recipe FAQs
- → Can I use brown rice instead of white rice?
Yes, you can substitute brown rice, but you'll need to adjust cooking time and liquid. Brown rice typically requires 50-60 minutes to cook and about ½ cup more liquid. Consider partially cooking the brown rice first for more reliable results.
- → Can I use rotisserie chicken for this casserole?
Absolutely! Rotisserie chicken is a perfect time-saving option. Simply shred the meat and measure out the 2 cups needed. The seasoning from rotisserie chicken adds even more flavor to the finished dish.
- → How can I make this casserole ahead of time?
You can prepare the entire mixture up to 24 hours ahead and store it covered in the refrigerator. When ready to cook, let it sit at room temperature for 30 minutes, then add about 10 minutes to the baking time since it will be starting cold.
- → What can I use instead of frozen peas?
Green beans, broccoli florets, or frozen mixed vegetables make excellent substitutes for peas. For a different flavor profile, consider corn, diced bell peppers, or asparagus pieces. Just ensure vegetables are cut small enough to cook through.
- → How do I store and reheat leftovers?
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 2-3 minutes. For best results when reheating larger portions, cover with foil and warm in a 350°F oven for 15-20 minutes.
- → Can this casserole be frozen?
Yes, it freezes beautifully! Cool completely, then transfer to a freezer-safe container and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating. For best texture, freeze before the final broiling step.
