Essential Ingredients for High-Protein Chicken Casserole

This nourishing and protein-packed casserole comes together with a handful of simple, wholesome ingredients.

• Chicken: 3 cups cooked chicken, chopped or shredded
• Rice: 2 cups cooked brown rice
• Broccoli: 1 large head of broccoli, cut into small florets
• For the High-Protein Creamy Sauce:
  • 1 cup plain Greek yogurt
  • ½ cup low-sodium chicken broth
  • ½ cup shredded low-fat mozzarella or cheddar cheese, divided
• Aromatics: 1 small onion, chopped & 2 cloves of garlic, minced
• Fat: 1 tablespoon olive oil
• Seasoning: Salt and black pepper to taste

Ingredients Notes

A little more detail on our key ingredients will ensure your casserole is as healthy and delicious as possible.

• The Chicken: Using pre-cooked chicken, like a rotisserie chicken or some meal-prepped baked chicken breasts, is a fantastic shortcut for this recipe. You want about 3 cups of chopped or shredded chicken. This lean protein is the primary component that makes this casserole so incredibly filling and high in protein.
• The Brown Rice: For the most nutritional benefit, this recipe uses cooked brown rice. Brown rice is a fantastic source of whole grains, providing complex carbohydrates for sustained energy and a great amount of dietary fiber. You can easily cook the rice ahead of time to make the casserole assembly even faster.
• The Greek Yogurt: The secret to our healthy and high-protein creamy sauce is plain, unsweetened Greek yogurt. It provides a wonderful, luscious, creamy texture and a subtle tang, along with a huge boost of extra protein. Make sure you use a plain variety, not a sweetened or flavored one.
• The Broccoli: Fresh broccoli florets add a beautiful pop of colour, a wonderful texture, and a huge dose of vitamins and fiber to this dish. It’s best to cut them into small, bite-sized florets so they become perfectly tender as the casserole bakes.

How to Make High-Protein Chicken Casserole

Let’s walk through the simple steps to assemble and bake this perfect meal prep dish.

• Step 1: Prepare the Oven and Sauté Aromatics. First, preheat your oven to 190°C (375°F) and lightly grease a 9×13 inch baking dish. In a small skillet, heat the olive oil over medium heat. Add the chopped onion and cook for 4-5 minutes, until it has softened, then add the minced garlic and cook for one more minute until fragrant.
• Step 2: Create the Casserole Mixture. In a very large mixing bowl, combine the cooked brown rice, the shredded chicken, the broccoli florets, and the sautéed onion and garlic.
• Step 3: Make the High-Protein Sauce. In a separate medium bowl, whisk together the plain Greek yogurt and the chicken broth until it is smooth. Stir in ¼ cup of the shredded cheese, and season with salt and pepper.
• Step 4: Combine and Assemble. Pour the prepared Greek yogurt sauce into the large bowl with the chicken and rice mixture. Gently stir everything together until all the ingredients are evenly combined and coated in the creamy sauce.
• Step 5: Bake the Casserole. Pour the mixture into your prepared baking dish and spread it into an even layer. Top the casserole evenly with the remaining ¼ cup of shredded cheese. Bake, uncovered, for 25-30 minutes.
• Step 6: Serve and Enjoy. The casserole is done when it is heated all the way through and the cheese on top is melted and bubbly. Let the casserole rest for a few minutes before you slice and serve it.

Storage Options

This high-protein chicken casserole is the absolute perfect recipe for your weekly meal prep. Once the casserole has cooled completely, you can slice it into individual portions and place them in airtight containers. It will stay fresh and delicious in the refrigerator for up to 5 days, providing you with a perfect, ready-to-eat post-workout meal or a healthy lunch.

This casserole also freezes very well. You can wrap individual cooled slices in plastic wrap and foil and store them in a freezer-safe bag for up to 3 months.

Variations and Substitutions

This healthy casserole is a fantastic and versatile base that you can easily adapt. You can swap the brown rice for another healthy whole grain like quinoa for an even bigger protein boost. Feel free to use other nutritious vegetables like chopped spinach, bell peppers, or cauliflower instead of the broccoli. For a different flavour, you can add other seasonings to the sauce, like a teaspoon of smoked paprika or a pinch of red pepper flakes.

Practical & Valuable Tips

For the best texture, it’s a great idea to use rice that has been cooked and slightly cooled, as it will hold its shape better in the casserole. To make this recipe even faster, you can use pre-cooked rice packets from the store. Finally, for the creamiest possible sauce with no lumps, make sure you whisk the Greek yogurt and broth together thoroughly before you combine them with the other ingredients.
