How to Make High Protein Cheesy Chicken and Broccoli Casserole Recipe
Step 1: Preheat and Prepare
Start by heating your oven to 400 degrees Fahrenheit. This higher temperature helps to roast the chicken and broccoli perfectly while melting the cheese to a beautiful golden finish. Preheating ensures even cooking from the moment your casserole hits the oven.
Step 2: Season the Chicken
Cut your chicken breast into 1-inch cubes so they cook evenly and stay juicy. Toss the chicken with garlic powder, onion powder, and salt to coat every bite with flavor. This simple seasoning mix keeps the protein delicious without being heavy.
Step 3: Make the Creamy Sauce
In a bowl, combine the cream of mushroom soup with the low-fat Greek yogurt. Stir these together until smooth, creating a rich, tangy base that will coat the chicken and broccoli, giving the casserole its signature creamy texture while keeping it light.
Step 4: Layer the Ingredients
Spread your chopped broccoli evenly across an 11×17-inch baking pan to create a fresh bed of green. Layer the seasoned chicken cubes on top, distributing evenly to make sure every scoop is balanced and flavorful.
Step 5: Add the Sauce and Cheese
Pour the mushroom and Greek yogurt mixture over the chicken and broccoli, spreading it out so every piece is generously coated. Then, sprinkle shredded cheddar cheese all over the top. This final cheesy layer is what makes the casserole irresistibly gooey and golden.
Step 6: Bake to Perfection
Cover the dish with foil to keep the moisture locked in, and bake for 30 minutes. After that, remove the foil and bake for another 10 minutes so the cheese bubbles and turns a gorgeous, appetizing golden brown. Once done, your High Protein Cheesy Chicken and Broccoli Casserole Recipe is ready to enjoy!
How to Serve High Protein Cheesy Chicken and Broccoli Casserole Recipe
Garnishes
To elevate this casserole even more, sprinkle freshly chopped parsley or chives right before serving. Their fresh, green bite adds a lovely pop of color and subtle herbal brightness that cuts through the richness.
Side Dishes
This casserole stands alone as a filling meal, but if you’re looking to round out the plate, consider a crisp mixed green salad with a light vinaigrette or some roasted garlic mashed potatoes. Both options complement the creamy, cheesy flavors without overwhelming your taste buds.
Creative Ways to Present
Serve individual portions in small ramekins for an elegant dinner party style, or spoon the casserole over a bed of steamed quinoa or brown rice to create a heartier, multi-textured meal. Adding toasted almonds or sunflower seeds on top offers a delightful crunch and nutty twist.
Make Ahead and Storage
Storing Leftovers
If you have leftovers from the High Protein Cheesy Chicken and Broccoli Casserole Recipe, store them in an airtight container in the refrigerator. They will stay fresh and tasty for up to 3 days, making it easy to enjoy a nutritious lunch or dinner later in the week.
Freezing
This casserole freezes beautifully. After baking and cooling, transfer portions into freezer-safe containers or freeze the entire dish. It can be stored for up to 2 months. Thaw overnight in the fridge before reheating to maintain that creamy texture and rich flavor.
Reheating
Reheat leftovers in the oven at 350 degrees Fahrenheit for about 15-20 minutes until warmed through and the cheese is slightly bubbly again. If in a hurry, a microwave works too—just cover to keep moisture and heat in evenly.
FAQs
Can I use frozen broccoli in this recipe?
Absolutely! Just make sure to thaw and drain it well before using so the casserole doesn’t become watery. Frozen broccoli is a great time-saver without sacrificing flavor.
Is it possible to make this recipe dairy-free?
Yes, you can substitute the Greek yogurt and cheddar cheese with dairy-free alternatives like coconut yogurt and vegan cheese. The flavor will be a bit different but still delicious and creamy.
How can I add more vegetables to this casserole?
Feel free to toss in other veggies like mushrooms, bell peppers, or carrots along with the broccoli. Just chop everything evenly so they cook within the same timeframe.
What if I want extra crispiness on top?
Try sprinkling some panko breadcrumbs mixed with a little melted butter on top before baking uncovered in the last 10 minutes. This layer will give you a delightful crunchy topping.
Can I use chicken thighs instead of breasts?
Yes, chicken thighs are juicier and add a richer flavor. Just adjust cooking time slightly if needed to ensure they are fully cooked and tender.
