Wholesome Ingredients for This Healthy Broccoli Chicken Casserole

We love how each ingredient in this casserole contributes both flavor and nutrition. Here’s what makes some of the key ingredients so great:

• Chicken: A lean source of protein, perfect for creating a hearty dish. You can use either diced cooked chicken or shredded rotisserie chicken to save time.
• Broccoli: This nutrient-dense vegetable is an excellent source of vitamins and minerals, including potassium and folate. Feel free to use frozen broccoli florets if fresh isn’t available to you.
• Whole-wheat pasta: Compared to traditional pasta, whole wheat offers higher levels of fiber and complex carbohydrates, keeping your energy steady after meals.

Healthy Broccoli Chicken Casserole Ingredients

• 8 ounces uncooked pasta (whole-wheat rotini recommended)
• 1 large head of broccoli, cut into bite-sized florets (about 1 pound)
• 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

• 2 cups (8 ounces) shredded sharp cheddar cheese, divided

How to Make Healthy Broccoli Chicken Casserole

1. Preheat your oven to 400°F (205°C).
2. Bring a large pot of generously salted water to a boil. Cook the pasta until it’s al dente, adding the broccoli to the pot during the final minute of cooking. Drain and set aside.
3. In a large sauté pan, heat the olive oil or butter over medium-high heat. Sauté the onion for 3 minutes, then add the mushrooms and garlic. Cook until the mushrooms soften and release their moisture, about 5 more minutes.
4. Sprinkle the flour over the sautéed onion mixture and stir constantly for 1 minute to cook out the raw flour taste.
5. Gradually add the chicken or vegetable stock, stirring to incorporate any lumps, followed by the milk, Dijon mustard, and seasonings (salt and pepper).
6. Bring the sauce to a gentle simmer, stirring frequently, until it thickens. Remove from heat and stir in 1 cup of shredded cheddar cheese until smooth. Taste and adjust seasoning, if needed.
7. In a 9 x 13-inch baking dish, combine the pasta, broccoli, chicken, and mushroom sauce. Toss together, ensuring everything is evenly coated.
8. Spread the mixture into an even layer. Bake uncovered for 15 minutes. Sprinkle the remaining shredded cheddar cheese over the top and return to the oven for another 10 minutes, or until the cheese melts and begins to bubble.
9. Let the casserole cool slightly. Garnish with freshly cracked black pepper or chopped parsley, if desired, and serve warm.

How to Customize This Healthy Broccoli Chicken Casserole for Your Diet

• Gluten-Free: Swap the pasta for a gluten-free variety and use a GF all-purpose flour for the sauce.
• Keto-Friendly: Replace the pasta with cauliflower florets or spaghetti squash to lower the carbs significantly.
• Vegetarian: Simply omit the chicken and double the broccoli, or add chickpeas for added protein.
• Dairy-Free: Substitute a plant-based milk and vegan cheese products for the sauce and topping. Use nutritional yeast for an added cheesy flavor.
