One pan. One oven. Dinner for the whole family — and leftovers you’ll actually look forward to the next day.
This chicken and rice casserole is the kind of recipe that quietly becomes a household staple. It’s creamy, cheesy, loaded with tender chicken and perfectly cooked rice, and it bakes all in one dish while you get on with your evening.
No complicated techniques. No fancy equipment. No standing over a stove.
And here’s what nobody talks about with casseroles: the rice cooks directly in the dish, absorbing all the broth and seasoning as it bakes. You’re not pre-cooking rice separately. It all happens together, which is honestly a little bit of a game-changer for a weeknight dinner.
Stick around — the Pro Tips section has a few things that make the difference between a good casserole and one people ask you to make again the next week.
What You’ll Need
For the Casserole
- 700g (about 1.5 lbs) boneless, skinless chicken breasts or thighs, cut into bite-sized pieces
- 1 cup (190g) long-grain white rice, uncooked
- 2 cups (480ml) chicken broth (low sodium preferred)
- 1 cup (240ml) whole milk
- 1 can (300g / 10.5 oz) cream of chicken soup
- 1 cup (150g) frozen peas
- 1 cup (150g) frozen diced carrots (or fresh, finely diced)
- 1 medium yellow onion, finely diced
- 3 cloves of garlic, minced
- 1 cup (100g) shredded cheddar cheese, divided
- 1/2 cup (50g) shredded mozzarella cheese
- 1 teaspoon of garlic powder
- 1 teaspoon of onion powder
- 1/2 teaspoon of smoked paprika
- 1 teaspoon of fine sea salt
- 1/2 teaspoon of black pepper
- 2 tablespoons of olive oil or unsalted butter
- Fresh parsley, chopped, to garnish
Tools You’ll Need
- A 9×13 inch (23×33 cm) baking dish or large oven-safe casserole dish
- A large mixing bowl
- A sharp chef’s knife
- A cutting board
- A wooden spoon or silicone spatula
- Aluminum foil
- Measuring cups and spoons
- A box grater (for the cheese)
Pro Tips
These are the details that separate a great casserole from a mediocre one.
- Cover it for most of the bake time. The foil traps steam, which is what cooks the rice through. Remove it only for the last 15 minutes so the cheese can go golden and bubbly. Skip this step and you’ll end up with crunchy, undercooked rice in the middle.
- Use chicken thighs if you can. Chicken breasts work fine, but thighs stay much more tender and juicy through the long bake time. If you’ve had a dry casserole before, thighs are usually the fix.
- Don’t rinse the rice. Normally you rinse rice to remove starch. Here, you want that starch — it helps thicken the creamy sauce as everything bakes together.
- Let it rest before serving. Five minutes out of the oven makes a real difference. The liquid finishes absorbing and everything sets up properly. Cut into it too soon and it’ll be soupy.
- Grate your own cheese. Pre-shredded cheese is coated in anti-caking agents that prevent it from melting smoothly. A block of cheddar grated fresh takes two minutes and melts into a much better topping.
How to Make Chicken and Rice Casserole
Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C).
Grease your 9×13 baking dish lightly with butter or cooking spray. Set aside.
Step 2: Season the Chicken
In a large bowl, toss your bite-sized chicken pieces with garlic powder, onion powder, smoked paprika, salt, and pepper. Add 2 tablespoons of olive oil and mix until evenly coated.
Step 3: Mix the Base
In the same bowl, add the uncooked rice, chicken broth, milk, and cream of chicken soup. Stir together until combined.
Add the diced onion, minced garlic, frozen peas, and frozen carrots. Give everything one more stir.
Step 4: Assemble
Pour the rice and vegetable mixture into your prepared baking dish and spread it evenly.
Scatter the seasoned chicken pieces on top, distributing them across the surface so every serving gets a good amount.
Sprinkle half of the shredded cheddar (1/2 cup) evenly over everything.
Step 5: Bake Covered
Cover tightly with aluminum foil and bake at 375°F (190°C) for 45 minutes.
This is the part where the rice cooks, the chicken begins to cook through, and all those flavors start coming together.
Step 6: Add the Cheese Topping
Remove the foil carefully (steam will escape — watch your hands).
Sprinkle the remaining cheddar and all of the mozzarella evenly across the top.
Return to the oven uncovered and bake for another 15 minutes, until the cheese is melted, bubbly, and golden in spots.
Step 7: Rest and Serve
Remove from the oven and let the casserole rest for 5 minutes.
Garnish with fresh chopped parsley and serve straight from the dish.
Substitutions and Variations
| Ingredient | Swap It For |
|---|---|
| Chicken breasts/thighs | Rotisserie chicken (shredded, add in Step 4) |
| Long-grain white rice | Jasmine rice — same cook time, slightly floral flavor |
| Cream of chicken soup | Cream of mushroom soup for an earthier flavor |
| Whole milk | Half-and-half for a richer sauce, or unsweetened oat milk to keep it dairy-light |
| Cheddar + mozzarella | Gruyère, Colby Jack, or pepper jack for a kick |
| Frozen peas + carrots | Frozen broccoli, corn, green beans, or diced bell pepper |
| Chicken broth | Vegetable broth (if using leftover cooked chicken) |
Gluten-free? Most cream of chicken soups contain wheat flour. Swap for a certified GF version or make a quick homemade version with butter, cornstarch, broth, and milk.
Want a crunchier topping? Mix 1/2 cup of panko breadcrumbs with a tablespoon of melted butter and scatter over the cheese before the uncovered bake. It adds a great texture contrast.
Feeding a crowd? This recipe scales up easily. Double it and use two baking dishes. The bake time stays the same.
Make-Ahead Tips
This casserole is genuinely great for getting ahead of the week.
- Fully assemble, don’t bake: Cover tightly with plastic wrap + foil and refrigerate for up to 24 hours. When you’re ready, remove the plastic wrap, cover with just foil, and bake as directed — add 10 extra minutes since it’s going in cold.
- Par-bake and finish later: Bake the covered portion (45 minutes), let it cool completely, refrigerate. Finish the uncovered cheese bake the next day at 375°F for 20 minutes.
- Freeze it unbaked: Assemble, cover with a double layer of foil, and freeze for up to 2 months. Thaw overnight in the refrigerator before baking as usual.

One thing worth knowing: chicken thighs have nearly twice the iron content of chicken breasts, which makes this casserole a surprisingly solid source of iron when you use them.
Meal Pairing Suggestions
This casserole is a full meal on its own, but if you want to round things out:
- A simple green salad with a sharp vinaigrette cuts through the richness nicely
- Roasted broccoli or asparagus on the side adds color and crunch
- Crusty dinner rolls for mopping up the creamy sauce at the bottom of the dish
- A light soup as a starter if you’re feeding guests and want the meal to feel more substantial
- Steamed green beans with butter and garlic are a classic pairing
Leftovers and Storage
This is one of those dishes that genuinely tastes better the next day.
- Refrigerator: Store covered for up to 4 days. The rice absorbs more liquid overnight and the flavors deepen.
- Reheating: Add a splash of chicken broth or milk before reheating to loosen it up. Microwave in 90-second intervals, stirring between each, or warm in a covered oven dish at 350°F (175°C) for 15 to 20 minutes.
- Freezer: Freeze individual portions in airtight containers for up to 3 months. Thaw overnight in the fridge before reheating.
Leftover tip: scoop cold casserole into a flour tortilla with a little sour cream and hot sauce for a quick next-day wrap. It works surprisingly well.
FAQ
Can I use brown rice instead of white rice?
You can, but the bake time needs to increase significantly. Brown rice typically needs 30 extra minutes of covered baking time and more liquid — add an extra 1/2 cup of broth. Most people find it easier to just use white rice here.
My casserole came out soupy. What happened?
A few possible causes: the foil wasn’t sealed tightly enough (steam escaped), the lid was lifted during baking, or it wasn’t rested long enough before serving. Give it the full 5-minute rest and make sure the foil is crimped tight next time.
Can I use pre-cooked or leftover chicken?
Yes, and it actually saves time. Shred or chop your cooked chicken and stir it directly into the rice mixture in Step 3. Reduce the total bake time by about 10 to 15 minutes since you’re not cooking raw chicken through.
Do I need to cook the vegetables before adding them?
No. The frozen peas and carrots cook through during the baking time. If using fresh carrots, dice them small (about 1/4 inch) so they have time to soften properly.
Can I make this in a slow cooker?
Yes. Add everything except the cheese to a slow cooker and cook on low for 4 to 5 hours or high for 2 to 3 hours. In the last 20 minutes, add the cheese on top, cover, and let it melt. The texture will be softer than the oven version.
The rice on top is drier than the rice underneath. Normal?
Totally normal. The rice on top is less submerged in liquid and sits closer to the cheese. It’s a texture thing — some people love it, some prefer to stir it in. Either way, it’s fine.
Wrapping Up
Casseroles get underestimated. People hear “one pan dinner” and assume boring, but this one is the kind of recipe that makes people scrape the dish clean and ask you for the recipe before they’ve finished eating.
It’s the definition of a reliable weeknight meal — minimal prep, zero babysitting, and enough servings to cover dinner tonight and lunch tomorrow.
Make it once this week and see what happens. Then come back and drop a comment below — I want to know what cheese you used, what vegetables you swapped in, and whether you did the panko topping (please do the panko topping). 😄
