Ingredients

  

• Chicken: 1.5–2 pounds boneless, skinless chicken breasts or thighs, cut into bite-size pieces
• Rice: 1.5 cups uncooked long-grain white rice (or parboiled). For brown rice, see notes in the FAQs.
• Broth: 3 cups low-sodium chicken broth
• Creamy base: 1 cup plain Greek yogurt (2% or 5%) or 6 oz light cream cheese, softened
• Veggies: 1 medium onion (diced), 2 cups broccoli florets (fresh or frozen), 1 cup sliced mushrooms (optional), 1 cup frozen peas and carrots
• Cheese: 1–1.5 cups shredded cheddar, part-skim mozzarella, or Monterey Jack
• Flavor boosters: 3 cloves garlic (minced), 1 teaspoon onion powder, 1 teaspoon smoked paprika, 1 teaspoon dried thyme or Italian seasoning
• Binders: 1 tablespoon olive oil or avocado oil
• Crunchy topping (optional): 1/2 cup panko or whole-wheat breadcrumbs
• Salt and pepper: To taste
• Fresh herbs (optional): Parsley or chives for garnish

Method

 

1. Preheat and prep: Heat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish. Rinse the rice under cold water until it runs mostly clear to remove excess starch.
2. Sauté aromatics: Warm the oil in a large skillet over medium heat. Add onion and a pinch of salt. Cook 4–5 minutes until softened, then stir in garlic for 30 seconds until fragrant.
3. Add veggies: Stir in mushrooms and cook 3–4 minutes until they release moisture. If using fresh broccoli, toss it in for 2 minutes to take off the raw edge. If using frozen broccoli, keep it frozen for now.
4. Season the chicken: Pat the chicken dry. Season with 1 teaspoon salt, 1/2 teaspoon pepper, smoked paprika, onion powder, and thyme. You don’t need to fully cook it on the stove—just make sure it’s evenly seasoned.
5. Mix the creamy base: In a bowl, whisk Greek yogurt (or softened light cream cheese) with 1/2 cup of the broth until smooth. This prevents curdling and helps it spread evenly.
6. Combine in the dish: Add rinsed rice to the baking dish. Top with the sautéed onion/garlic/veggies, seasoned chicken, frozen peas and carrots, and broccoli (if frozen, add it now). Pour in the remaining broth plus the yogurt mixture. Stir gently to distribute everything. Taste the liquid and adjust salt and pepper if needed.
7. Cover and bake: Cover tightly with foil. Bake for 35 minutes. This traps steam and cooks the rice through without drying out the chicken.
8. Add cheese: Remove the foil and gently fluff the rice. Sprinkle cheese evenly over the top. If using panko, toss it with a teaspoon of olive oil and scatter over the cheese.
9. Finish baking: Return to the oven uncovered for 10–15 minutes, until the cheese melts and the top turns golden. The rice should be tender and most liquid absorbed.
10. Rest and garnish: Let the casserole rest for 8–10 minutes. This helps the rice set. Sprinkle with chopped parsley or chives and serve.

Why This Recipe Works

Save

This casserole checks all the boxes for a high-protein, no-stress meal. The chicken is cooked right in the casserole, so it stays moist and soaks up flavor from the broth and seasonings.

Using Greek yogurt (or light cream cheese) gives you creaminess and tang without heavy cream. The rice cooks in the same dish, which means fewer dishes and a hands-off finish in the oven. And because it’s a pantry-friendly recipe, you can easily swap veggies or seasonings based on what you have.

Keeping It Fresh

Let leftovers cool until just warm before storing.

Move them into shallow, airtight containers to chill quickly. In the fridge, the casserole keeps well for 3–4 days. For longer storage, portion into freezer-safe containers and freeze for up to 3 months.

Reheat in the microwave with a splash of broth or water to bring back moisture, or warm in a 325°F oven covered with foil until hot.

Health Benefits

• High-quality protein: Chicken delivers lean protein for muscle repair and lasting fullness. Greek yogurt adds extra protein and creaminess.
• Smart carbs: Rice provides steady energy. Use long-grain white for speed, or swap in brown rice for more fiber (see FAQs).
• Nutrient-dense veggies: Broccoli, peas, and carrots contribute fiber, vitamin C, vitamin A, and potassium.
• Lighter comfort: Using yogurt or light cream cheese reduces saturated fat while keeping that cozy, creamy texture.
• Balanced plate in one dish: Protein, carbs, and veggies come together, making portions simpler and meal prep easier.

What Not to Do

• Don’t skip rinsing the rice: Excess starch can make the casserole gummy instead of fluffy.
• Don’t overbake: Dry chicken happens fast.

  Keep it covered for the first bake and only uncover to melt and brown the topping.

• Don’t use high-sodium broth without adjusting: It can push the dish into salty territory. Taste the liquid before baking.
• Don’t add yogurt straight to boiling-hot liquid: It may curdle. Whisk it with a little warm broth first.
• Don’t overcrowd with too many watery veggies: Mushrooms and zucchini release water.

  Sauté them first or reduce the amount to avoid soupy results.

Variations You Can Try

• Southwest style: Use chili powder and cumin, swap peas and carrots for corn and black beans, and top with pepper jack. Add a squeeze of lime and chopped cilantro.
• Herby lemon: Add lemon zest to the yogurt mix, use fresh dill and parsley, and swap cheddar for mozzarella or feta.
• Buffalo chicken: Stir 2–3 tablespoons buffalo sauce into the yogurt mixture and top with a mix of mozzarella and blue cheese crumbles.
• Extra-lean: Use chicken breast, reduce cheese to 3/4 cup, and load up on broccoli and mushrooms. It stays satisfying with fewer calories.
• High-fiber: Use brown rice and add chickpeas.

  Increase broth and bake time as noted in the FAQs.

FAQ

Can I use brown rice instead of white?

Yes. Brown rice needs more liquid and time. Use 1.5 cups brown rice with 3.75–4 cups broth.

Bake covered for 55–65 minutes before adding cheese, then finish uncovered for 10–15 minutes. Check that the rice is tender before pulling it from the oven.

Can I use pre-cooked or rotisserie chicken?

Absolutely. Stir in shredded cooked chicken after the first bake when you add the cheese.

Reduce the broth by about 1/2 cup since the chicken won’t release juices, and bake uncovered just until the top is melted and golden.

How do I make it dairy-free?

Swap the yogurt for a thick, unsweetened dairy-free yogurt or use a cashew cream. Use a dairy-free cheese that melts well, or skip cheese and add toasted breadcrumbs for crunch. Check that your broth is dairy-free too.

Can I prep this ahead?

Yes.

Assemble everything up to the baking step, cover, and refrigerate for up to 24 hours. Add an extra 5–10 minutes to the initial covered bake since it will be starting cold. Alternatively, bake fully, cool, and portion for easy meals all week.

Why is my casserole watery?

Common reasons include not rinsing rice, using too many high-water veggies without sautéing, or uncovering too early.

Make sure the foil is tight during the first bake so the rice steams properly. Let the dish rest after baking so the liquids settle.

What if I don’t have Greek yogurt?

Light cream cheese works well. Soften it and whisk with warm broth until smooth.

You can also use cottage cheese blended until creamy for a high-protein swap.

Can I add more protein?

Yes. Stir in a can of drained chickpeas, add extra chicken, or sprinkle with a little grated Parmesan for a protein bump. Just avoid cramming the dish too full or the rice may not cook evenly.

How do I know the chicken is done?

When the casserole is finished, chicken pieces should be opaque and reach an internal temperature of 165°F (74°C).

If you’re unsure, cut into a larger piece to check there’s no pink and the juices run clear.
