This broccoli chicken divan casserole is an easy recipe that has been devoured and enjoyed for decades. Get ready for this dish to be your new favorite dinner!
Preheat oven to 400°F. Lightly spray a 2-quart (8x8-inch) casserole dish with nonstick spray and set aside.
Chop the broccoli (crowns and stems) into bite-sized pieces. Bring a large pot of water to a boil, then add the broccoli. Boil for 2-3 minutes, until tender-crisp. Drain well.
1 pound broccoli florets
In a large bowl, combine the soup, ½ cup Monterey jack cheese, cheddar cheese, milk, sour cream, mustard, garlic powder, and pepper. Whisk well to combine.
10.5 ounces condensed cream of chicken soup, 1 cup shredded Monterey jack cheese, ½ cup shredded cheddar cheese, ⅓ cup milk, ⅓ cup sour cream, 1 teaspoon whole grain mustard, ½ teaspoon garlic powder, ½ teaspoon ground black pepper
Gently stir in the steamed broccoli and chicken to coat. Transfer the mixture to the prepared casserole dish. Sprinkle on the remaining cheese.
2½ cups cubed cooked chicken
In a small bowl, combine the breadcrumbs and melted butter and stir. Sprinkle the topping over the casserole.
¼ cup breadcrumbs, 2 tablespoons unsalted butter
Bake for 15-20 minutes, or until the casserole is bubbly and the topping is lightly browned.
Serve as is, or over rice, noodles, or mashed potatoes.
Notes
*Frozen broccoli can be used instead of fresh. Simply thaw and add it to the filling.**Cream of mushroom or cream of celery will also work well.***Plain Greek yogurt is a good substitute.****I like using up leftover chicken, shredded chicken. You can also use a rotisserie chicken or canned chicken to save time.Tips:
Easily double this recipe and bake it in a 4-quart baking dish (9x13-inches) to feed 8 people! Bake for an additional 10-15 minutes.
Feel free to swap the broccoli out for other vegetables such as asparagus, zucchini, cauliflower, or peas. I like to use whatever we have on hand whenever possible.
