How to Make High Protein Cheesy Chicken and Broccoli Casserole Recipe
Step 1: Prep and Season
First things first, preheat your oven to 400 degrees F so it’s scorching hot and ready when you are. Then, cut the chicken into bite-sized cubes and toss them with garlic powder, onion powder, and salt. This seasoning step is the secret to layering flavor early on—don’t skip it!
Step 2: Mix Creamy Base
In a bowl, blend the cream of mushroom soup with the Greek yogurt until smooth and creamy. This mixture will give the casserole its luscious texture and tangy undertones, making each bite velvety without being heavy.
Step 3: Arrange the Ingredients
Grab an 11×17-inch baking dish and spread the chopped broccoli evenly across the bottom. Next, scatter the seasoned chicken over the broccoli. This layering helps the flavors meld perfectly during baking.
Step 4: Add the Creamy Topping
Pour your creamy mushroom and yogurt mixture evenly on top of the chicken and broccoli. This ensures every piece gets coated in that wonderful richness.
Step 5: Cheese It Up and Bake
Finally, sprinkle the shredded cheddar cheese over the top for that iconic golden crust. Cover the dish with foil and bake for 30 minutes. Then, remove the foil and bake for another 10 minutes to let the cheese bubble and brown to perfection.
Step 6: Serve Hot
Once baked, pull the casserole from the oven, let it sit for a few minutes, then dive in while it’s still warm and comforting. This High Protein Cheesy Chicken and Broccoli Casserole Recipe tastes best hot, with that delightful gooey cheese stretching with every serving.

Garnishes
Sprinkle fresh chopped parsley or chives on top to add a burst of color and fresh, herbaceous notes that brighten the casserole’s rich flavors. A light dusting of crushed red pepper flakes can also add an exciting kick.
Side Dishes
This casserole stands strong on its own, but pairing it with a crisp garden salad or some garlic bread can round out the meal and provide a wonderful contrast in texture and temperature.
Creative Ways to Present
For a fun twist, serve this casserole inside hollowed-out bell peppers or alongside steamed whole grains like quinoa or brown rice. This turns the dish into a complete, protein-packed feast that’s as beautiful as it is tasty.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers (though it rarely happens!), store them in an airtight container in the refrigerator. The casserole will keep its flavor and texture beautifully for up to 3 days.
Freezing
You can freeze this casserole before baking by assembling it in a freezer-safe dish, covering tightly, and freezing for up to 2 months. When ready to eat, thaw overnight in the fridge and bake as directed.
Reheating
Reheat leftovers in a preheated oven at 350 degrees F for about 15-20 minutes or until warmed through. Cover loosely with foil to avoid drying out while the cheese gently melts again.
FAQs
Can I use other vegetables besides broccoli?
Absolutely! Cauliflower, spinach, or even mixed veggies work well. Just be sure to adjust cooking times if you use softer vegetables.
Is this casserole suitable for meal prep?
Yes, it’s a fantastic option for meal prep because it keeps well in the fridge and freezes nicely. Preparing it in advance saves time during busy weekdays.
Can I make this recipe dairy-free?
You can substitute the Greek yogurt and cheddar cheese with dairy-free alternatives like coconut yogurt and vegan cheese to suit dietary needs.
What can I use instead of cream of mushroom soup?
If you prefer, homemade cream sauce or cream of chicken soup can be swapped in. Just keep the creamy consistency for the best texture.
How can I add more flavor to this casserole?
Try adding smoked paprika, a splash of hot sauce, or fresh herbs like thyme and rosemary to the seasoning mix for extra depth and complexity.
