Equipements Needed

• A 9×13 inch baking dish – our trusty workhorse for this recipe.
• A large skillet – for building that incredible sauce.
• A medium mixing bowl – for combining our creamy base.
• A whisk – to get everything smooth and lump-free.
• Measuring cups and spoons – for getting those ratios just right.

Ingredients

• 3 cups cooked shredded chicken – from a rotisserie chicken or leftover baked breasts for a huge time-saver.
• 1 ½ cups uncooked long-grain white rice – the perfect texture for absorbing all that flavor.
• 1 medium yellow onion, diced – the savory foundation of our sauce.
• 2 cloves garlic, minced – because can you ever really have enough?
• 3 cups chicken broth – gives the rice something delicious to cook in.
• 1 cup whole milk – creates a rich, creamy base for our sauce.
• 4 oz cream cheese, softened – the secret to that luscious, velvety texture.
• ½ cup sour cream – adds a wonderful tang and more creaminess.
• 1 ½ cups shredded cheddar cheese, divided – for cheesy goodness inside and a golden top.
• 1 tsp each dried thyme, paprika, and onion powder – our simple but powerhouse herb blend.
• Salt and black pepper to taste – to make all the flavors pop.

Step By Step

1. First, preheat your oven to 375°F (190°C) and grease that 9×13 baking dish. Get your ingredients prepped—it makes the process flow so smoothly.
2. In your large skillet over medium heat, sauté the diced onion until it’s soft and translucent, about 5 minutes. Add the minced garlic and cook for one more minute, just until it’s fragrant.
3. In your mixing bowl, whisk together the chicken broth, milk, softened cream cheese, and sour cream until it’s as smooth as you can get it. A few tiny cream cheese lumps are okay—they’ll melt away in the oven. Stir in your thyme, paprika, onion powder, a good pinch of salt, and a few cracks of black pepper.
4. Spread the uncooked rice evenly in the bottom of your prepared baking dish. Layer the shredded chicken on top of the rice. Pour the creamy herb sauce and the sautéed onions and garlic over everything. Give it a gentle stir right there in the pan to combine everything.
5. Cover the dish tightly with foil and bake for 55-60 minutes. The rice should be tender and have absorbed most of the liquid.
6. Carefully remove the foil—watch out for steam! Sprinkle the remaining cheddar cheese over the top. Return the dish to the oven, uncovered, for another 5-10 minutes, or until the cheese is beautifully melted and bubbly.
7. Let the casserole stand for about 10 minutes before serving. This is a crucial step! It allows everything to set up, making it much easier to scoop and serve.

Variations & Substitutions

• Gluten-Free: This recipe is naturally gluten-free! Just double-check that your chicken broth and pre-shredded cheese labels say gluten-free to be safe.
• Dairy-Free: Use your favorite unsweetened plain almond milk, dairy-free cream cheese, and sour cream. For the cheese topping, a dairy-free cheddar style shred works great.
• Veggie Boost: Feel free to stir in a couple of handfuls of fresh spinach or some thawed frozen peas right before adding the cheese topping.
• Rice Swap: Brown rice can be used, but you’ll need to increase the bake time by about 20-25 minutes and may need to add a little more broth.
• Herb Twist: Fresh herbs are wonderful here! Swap the dried thyme for a tablespoon of fresh chopped rosemary or dill.

Serving Ideas & Pairings

This casserole is a complete meal all on its own, but a simple side can really round things out. A crisp green salad with a tangy vinaigrette is my absolute favorite pairing—it cuts through the richness perfectly. Some simple roasted green beans or steamed broccoli also work beautifully. And if you’re feeding a real hungry crowd, a loaf of crusty garlic bread for dipping is never a bad idea.

Storage & Reheating

Let any leftovers cool completely before storing. They’ll keep in an airtight container in the refrigerator for up to 4 days. To reheat, the microwave is easiest—just splash a tablespoon of water or broth over a portion to keep it moist and heat in 60-second intervals, stirring in between, until hot. For a crisper top, reheat it in a 350°F oven in an oven-safe dish for about 15-20 minutes. You can also freeze this casserole! Assemble it (but don’t bake it), wrap it tightly in a few layers of plastic wrap and foil, and freeze for up to 3 months. Thaw in the fridge overnight before baking as directed.

Pro Tips

• Use a rotisserie chicken. Seriously, it’s the ultimate shortcut for quick dinner recipes and makes this so, so easy.
• Don’t skip letting it rest after baking. Those 10 minutes are what gives you clean slices instead of a saucy puddle.
• If your cream cheese is still a little cold, cube it and let it sit in the warm broth for a few minutes before whisking. It’ll blend much easier.
• Taste your sauce mixture before pouring it in. Broths have different salt levels, so you might need to adjust.
• And for the love of a golden crust, don’t forget that final uncovered bake to melt the cheese!

Frequently Asked Questions

• Can I use raw chicken instead of cooked? You can, but it changes the method. I’d recommend using 1.5 lbs of raw, cubed chicken breast. Brown it first in the skillet with the onions, then proceed. This ensures it cooks through safely.
• My rice is still hard. What happened? This usually means the dish wasn’t covered tightly enough, letting steam escape, or your oven runs cool. Just cover it back up and bake for another 10-15 minutes, checking every 5.
• Is this one of those healthy chicken recipes? It’s a hearty comfort food dish, but you can lighten it up! Use low-fat milk, reduced-fat cheese, and lean chicken breast. You’re still getting a balanced meal with protein, carbs, and veggies.
• Can I make this ahead of time? Absolutely. Assemble the entire casserole, cover, and refrigerate for up to 24 hours before baking. You may need to add 5-10 minutes to the bake time since it’s starting from cold.
