Ingredients of the High Protein Chicken Casserole
For the Chicken Base
- 2 lbs boneless, skinless chicken breasts, cooked and shredded
- 1 tbsp olive oil
- 1 tsp garlic powder
- 1 tsp smoked paprika
- Salt and black pepper to taste
For the Protein-Rich Cream Sauce
- 1 cup plain Greek yogurt (full-fat or 2%)
- 1/2 cup low-sodium chicken broth
- 1 cup shredded mozzarella cheese
- 1/4 cup grated parmesan cheese
- 2 cloves garlic, minced
For the Vegetables and Toppings
- 2 cups broccoli florets, steamed
- 1 cup chopped bell peppers
- 1/4 cup fresh parsley, chopped
Equipment / Tools Needed
- Large mixing bowl
- 9×13 inch baking dish
- Shredding forks
- Measuring cups and spoons
- Skillet for pre-cooking
Step-by-Step Instructions
Step 1: Prepare the Ingredients
Preheat your oven to 375°F (190°C). Ensure your chicken is fully cooked and shredded into bite-sized pieces. Steam the broccoli florets until they are bright green and tender-crisp to ensure they maintain their texture during the baking process.
Step 2: Mix the Sauce
In a large mixing bowl, whisk together the Greek yogurt, chicken broth, minced garlic, paprika, and half of the shredded mozzarella and parmesan cheeses. The mixture should reach a smooth, consistent texture with a light, creamy color.
Step 3: Combine Everything
Add the shredded chicken, steamed broccoli, and chopped bell peppers into the bowl with the sauce. Fold the mixture gently until every piece of chicken and vegetable is thoroughly coated in the creamy base, ensuring the spices are evenly distributed.
Step 4: Bake to Perfection
Transfer the mixture into your 9×13 baking dish, spreading it out into an even layer. Sprinkle the remaining mozzarella and parmesan over the top. Bake for 20 to 25 minutes, or until the cheese is bubbling and golden-brown in spots. The internal aroma should be savory and inviting.
Tips & Tricks
To keep the chicken moist, avoid overcooking it during the initial prep phase; poaching or slow-cooking the breasts until they just reach 165°F is ideal. If you prefer a crunchier top, you can place the dish under the broiler for the final two minutes of cooking.
Serving Suggestions
Serve this dish warm directly from the oven. It pairs beautifully with a side of quinoa or a crisp green salad tossed in a lemon vinaigrette to balance the richness of the casserole.
Variations / Substitutions
You can swap broccoli for asparagus or baby spinach depending on seasonal availability. For those who enjoy a bit of heat, add diced jalapeños or a teaspoon of red chili flakes to the sauce base.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to three days. To reheat, warm individual portions in the microwave or place back into the oven at 350°F until heated through, adding a splash of chicken broth if the sauce has thickened too much.

FAQ
Can I freeze this casserole?
Yes, you can freeze it, but it is best to do so before the final bake. Cover the dish tightly and freeze for up to two months, then thaw overnight in the refrigerator before baking as directed.
What can I use instead of Greek yogurt?
You can substitute with sour cream or a thick labneh. Note that these options may slightly alter the final protein content compared to Greek yogurt.
Can I make this ahead of time?
Absolutely, you can assemble the entire dish up to 24 hours in advance. Keep it covered in the refrigerator and simply add an extra 5-10 minutes to your baking time if cooking from cold.
How do I prevent the broccoli from becoming mushy?
The secret is to steam it until it is barely tender before adding it to the casserole. Because it continues to cook in the oven, starting with slightly undercooked vegetables ensures a better final texture.
