How to Make High Protein Cheesy Chicken and Broccoli Casserole Recipe
Step 1: Preheat Your Oven
The first thing to do is set your oven to 400 degrees Fahrenheit so it’s nice and hot when your casserole goes in. This helps the chicken cook evenly and the cheese melt beautifully into a bubbly golden topping.
Step 2: Season Your Chicken
Cut the chicken breast into 1-inch cubes to ensure every bite is tender and easy to eat. Toss the chicken thoroughly with garlic powder, onion powder, and salt. This step is crucial because it locks in flavor right before cooking.
Step 3: Mix the Creamy Base
In a mixing bowl, combine the cream of mushroom soup and low-fat Greek yogurt. Stir them together until smooth and creamy. This blend is what makes the casserole super moist and gives it a tangy richness that’s better than just plain soup.
Step 4: Layer the Broccoli and Chicken
Spread the broccoli pieces evenly in an 11×17-inch baking dish. Scatter the seasoned chicken cubes over the broccoli. This layering ensures every spoonful has a perfect balance of protein and greens.
Step 5: Pour Over the Creamy Mixture
Next, spread the mushroom and Greek yogurt mixture over the broccoli and chicken. This coating keeps everything moist during baking and binds the ingredients together with a velvety texture.
Step 6: Add the Cheese Topping
Sprinkle the shredded cheddar cheese right on top. It melts and browns in the oven, creating that irresistible cheesy crust everyone loves.
Step 7: Bake Covered, Then Uncovered
Cover the casserole dish with foil and bake for 30 minutes to allow the chicken and broccoli to cook through. Then, remove the foil and bake for an additional 10 minutes to get the cheese golden and bubbly. This two-step baking is the secret to perfectly cooked and melty results.
Step 8: Serve It Hot and Enjoy!
Once the casserole comes out of the oven, let it rest briefly before serving. Then dig in while it’s warm and gooey for a comforting meal that satisfies both taste buds and hunger.

Garnishes
A sprinkle of freshly chopped parsley or green onions adds a pop of color and mild freshness to the casserole’s rich flavors. For an extra kick, a pinch of red pepper flakes works beautifully.
Side Dishes
This casserole stands out on its own but pairs wonderfully with simple sides like a fresh mixed green salad, garlic bread, or even a light quinoa pilaf. These sides provide contrast and balance without overshadowing the main dish.
Creative Ways to Present
Serve this dish in colorful individual ramekins for a charming, portion-controlled presentation perfect for dinner parties or family meals. Alternatively, top each serving with a dollop of Greek yogurt or a drizzle of hot sauce to customize the flavor experience.
Make Ahead and Storage
Storing Leftovers
Let the casserole cool completely, then cover tightly and place in the refrigerator. It will stay fresh for up to 3 days, making it perfect for quick lunches or dinner reheats.
Freezing
You can freeze the casserole before baking to save time on busy days. Prepare as directed, cover well with foil or airtight wrap, and freeze for up to 3 months. When ready, bake from frozen, adding extra time as needed.
Reheating
To reheat, warm in the oven at 350 degrees Fahrenheit for 15-20 minutes or until heated through. For a quicker option, microwave individual portions but cover loosely to maintain moisture and avoid drying out.
FAQs
Can I use other vegetables instead of broccoli?
Absolutely! Cauliflower, green beans, or even asparagus work wonderfully as substitutes or additions to broccoli, adding their own textures and flavors to this high-protein casserole.
Is this recipe suitable for meal prep?
Definitely. The High Protein Cheesy Chicken and Broccoli Casserole Recipe stores well in the fridge and the freezer, making it a fantastic meal prep option to enjoy throughout the week with minimal effort.
Can I make it dairy-free?
For a dairy-free version, swap the cheddar cheese with a plant-based alternative and use coconut yogurt instead of Greek yogurt. The creamy texture might differ slightly but the flavor will still be delicious.
How can I increase the protein even more?
Adding beans or legumes like chickpeas, using extra chicken, or mixing in cottage cheese are great ways to bump up the protein content without compromising flavor or texture.
Is it okay to use fresh versus frozen broccoli?
Both work well but fresh broccoli tends to keep a better texture after baking. If you use frozen, make sure to thaw and drain it well to avoid excess moisture in your casserole.
