Swapping Classic Ingredients for Healthier Options

Our chicken and broccoli casserole is loaded with yummy goodness and healthy ingredients that can be enjoyed for dinner and leftover for lunch!

The recipes our mothers and grandmothers used to prepare used to have heavy ingredients and were cooked with excess fat. Today, we tend to be more health conscious by eating balanced meals and exercising. Although those recipes of the past are high in calories, it doesn’t mean that they don’t taste delicious (or that we don’t like them). These days it’s more common for people to recreate old recipes by substituting unhealthy ingredients for more natural and nutritious ones. And that’s exactly what we’ve done here! With ingredients like lean, white meat chicken breasts, high-protein greek yogurt, reduced-fat cheese, and healthy brown rice, we’ve cut down on calories while increasing nutrients!

Preparing this Nutritious Chicken and Broccoli Casserole

This ooey-gooey casserole is absolutle divine-tasting!

To start preparing this delicious recipe, you need to preheat the oven to 375º Fahrenheit. While the oven is preheating, grease a 9×9 casserole dish and set it aside for later. Note that this recipe uses cooked brown rice, so you can go ahead and do that while the chicken is cooking so it’s ready to go when you need it.

Place the chicken breasts in a sauce pan and season it with salt and pepper to taste. Then, add water to the pan and heat over medium-high, until boiling. Once boiling, reduce the heat to bring the water to a simmer and cook the chicken until it reaches an internal temperature of 165º Fahrenheit. This should take approximately 10 to 15 minutes. Remove the chicken from the water and let it sit until it is cool enough to shred. You will get approximately 2 cups of shredded chicken.

Meanwhile, add the broccoli to the simmering water and cook for 2 to 3 minutes, until it turns bright green in color and feels tender and crisp. Remove the broccoli from the pot. 

Strain the cooking liquid through a fine-mesh strainer, and save one and a half cups of it. Place the reserved cooking liquid back into the pot along with the cornstarch, garlic powder, onion powder, and celery salt. Cook over medium heat until thickened, anywhere from 5 to 10 minutes. Remove the thickened mixture from the heat and let it cool slightly for 5 minutes.

In a large bowl, mix together the thickened liquid, Greek yogurt, Dijon mustard, half of the shredded cheddar cheese, and shredded chicken. Season with salt and pepper to taste.

Now spread the cooked brown rice in an even layer in the bottom of the greased casserole dish. Add the broccoli in a second layer before pouring in the chicken mixture. Top the dish with the remaining cheddar cheese. Bake for 20 minutes, until the chicken and broccoli casserole is hot and bubbling. Be sure to let it stand for at least 10 minutes before serving. Grandma would be proud!
