High Protein Chicken and Rice Casserole to Satisfy Midweek Hunger

Sometimes, the middle of the week calls for something both nourishing and straightforward—this chicken and rice casserole fits that exact need. It’s the kind of dish you come home to after a long day, where the aroma of melted cheese mingling with herbs and garlic wraps around you like a soft blanket. The kitchen smells cozy, with just a hint of roasted mushrooms and sautéed onions teasing your senses before you even sit down.

I remember the first time I made this casserole; I was juggling dinner prep with a distracted mind, halfway through a phone call, and I almost forgot to add the garlic. Luckily, I caught myself just in time. The result was far from perfect, but honestly, that little imperfection made it feel even more like home—comfort food that’s forgiving and real. The tender chicken chunks mixed with the creamy, slightly tangy blend of Greek yogurt and cottage cheese gave every bite a subtle richness that kept me going back for more, even when I probably should’ve stopped.

Why You’ll Love It:

  • It’s packed with protein without feeling heavy—great if you’re after something filling but not greasy.
  • Combines wholesome ingredients like brown rice, broccoli, and mushrooms for a balanced meal in one dish.
  • It’s simple—and that’s kind of the point. No complicated steps, just a cozy, satisfying bake.
  • The creamy texture from cottage cheese and yogurt adds richness without needing extra cream.
  • Flexible enough to sneak in extra veggies if you want, though it’s already nicely loaded.

If you’re worried about leftovers, don’t be. This casserole reheats well, keeping its flavors intact, which is a small win when you don’t want to cook every single night.

Description

A hearty and nutritious high protein chicken and rice casserole, perfect for a wholesome family meal. This dish combines tender chicken breast, brown rice, and a creamy sauce packed with protein and flavor.


Ingredients

Scale

2 cups cooked brown rice
1.5 pounds boneless skinless chicken breasts, cut into bite-sized pieces
1 cup low-fat cottage cheese
1 cup plain Greek yogurt
1 cup shredded reduced-fat cheddar cheese
1 medium onion, finely chopped
2 cloves garlic, minced
1 cup low-sodium chicken broth
1 cup chopped broccoli florets
1 cup sliced mushrooms
1 tablespoon olive oil
1 teaspoon dried thyme
1 teaspoon dried oregano
1/2 teaspoon black pepper
1/2 teaspoon salt


Instructions

Preheat the oven to 375°F (190°C).
In a large skillet, heat olive oil over medium heat. Add the chopped onion and minced garlic, sauté for 3-4 minutes until softened.
Add the chicken pieces to the skillet and cook for 5-6 minutes until lightly browned but not fully cooked through.
Add the sliced mushrooms and chopped broccoli to the skillet and cook for an additional 3 minutes until vegetables begin to soften.
In a large mixing bowl, combine the cooked brown rice, low-fat cottage cheese, plain Greek yogurt, dried thyme, dried oregano, black pepper, and salt. Stir until well mixed.
Add the sautéed chicken and vegetable mixture to the rice mixture and stir to combine evenly.
Pour the chicken broth into the mixture and stir gently to incorporate.
Transfer the entire mixture into a greased 9×13 inch casserole dish and spread evenly.
Sprinkle the shredded reduced-fat cheddar cheese evenly over the top of the casserole.
Cover the casserole dish with aluminum foil and bake in the preheated oven for 30 minutes.
Remove the foil and bake for an additional 10-15 minutes until the cheese is melted and bubbly and the casserole is heated through.
Remove from oven and let cool for 5 minutes before serving.

Kitchen Notes: You don’t need anything fancy to pull this off—just a decent skillet and a casserole dish. I usually serve it with a simple side salad or some steamed greens to keep things fresh. Sometimes, I swap out broccoli for spinach or toss in some chopped bell peppers when I have them on hand, but I haven’t tried adding anything too wild, so I can’t promise how that’ll turn out. If you like it spicier, a pinch of chili flakes in the mix can add a nice kick, though that’s totally optional.

FAQ:

Can I use white rice instead of brown? You can, but brown rice gives a nuttier flavor and holds up better during baking.

Is it okay to freeze leftovers? Absolutely. Just thaw overnight in the fridge before reheating.

What if I don’t have Greek yogurt? Plain yogurt or sour cream might work, but the texture and tang will be a bit different.

This casserole is an easy way to fill your table with something warm and satisfying. Give it a try and see how it fits into your weeknight routine—you might just find yourself coming back for seconds.
