– 2 tablespoons butter or olive oil
– 1 small white onion, thinly sliced
– 8 ounces baby bella (cremini) mushrooms, thinly sliced
– 4 cloves garlic, minced
– 3 tablespoons flour
– 1 cup chicken or vegetable stock
– 1 1/2 cups milk

– 1/4 teaspoon freshly-cracked black pepper
– 2 cups (8 ounces) shredded sharp cheddar cheese, divided
– 2 cups diced (or shredded) cooked chicken
How to Make Healthier Broccoli Chicken Casserole
Step 1: Preheat the Oven
Heat oven to 400°F.
Step 2: Cook Pasta and Broccoli
Cook pasta in a large stockpot of generously-salted boiling water until it is al dente. About one minute before the pasta is done, add the broccoli to the boiling pasta water. Stir until combined. Drain both the pasta and broccoli, then set aside.
Step 3: Sauté Vegetables
In a large sauté pan over medium-high heat, heat the butter (or oil). Add the onion and sauté for about 3 minutes while stirring occasionally. Then add the mushrooms and garlic; sauté for an additional 5 minutes until mushrooms are cooked through.
Step 4: Prepare Sauce
Sprinkle flour evenly over the onion mixture. Stir until combined and cook for another minute. Gradually add in stock, stirring until mostly smooth. Next, pour in milk along with Dijon mustard, salt, and pepper. Continue cooking until the sauce simmers. Remove from heat and stir in one cup of shredded cheese until fully melted. Taste and adjust seasoning if needed.
Step 5: Combine Ingredients
In a large 9 x 13-inch baking dish, combine cooked pasta, broccoli, mushroom sauce, and chicken. Toss everything until well mixed. Smooth out into an even layer.
Step 6: Bake Casserole
Bake uncovered for about 15 minutes. Remove from oven; sprinkle remaining cheddar cheese on top. Bake for an additional 10 minutes or until cheese is melty.
Step 7: Serve
Serve warm with extra black pepper or fresh herbs on top if desired.

- Balance Creaminess: Adjust the milk based on preference; use less for a thicker sauce or more for creaminess.

Common Mistakes to Avoid
When making the Healthier Broccoli Chicken Casserole, it’s easy to overlook some key steps that can affect the final dish. Here are common mistakes to avoid.
- Skipping the pasta and broccoli timing: Adding broccoli too early or too late can lead to mushy or undercooked vegetables. Always add it to the boiling pasta water about one minute before draining.
- Neglecting to season properly: Without adequate seasoning, your casserole may taste bland. Taste your sauce before baking and adjust the salt and pepper as needed.
- Using low-quality cheese: Not all cheese melts well. Opt for good-quality sharp cheddar for a creamy texture and rich flavor in your casserole.
- Overbaking the casserole: Baking too long can dry out your dish. Keep an eye on cheese melting; once it’s bubbly and golden, it’s ready to serve.
- Not letting it rest before serving: Cutting into a hot casserole can cause it to fall apart. Allow it to rest for a few minutes after baking for better slices.
