Comfort in a Dish

This casserole brings together familiar flavors that evoke feelings of home.

With creamy chicken and bright green broccoli, it becomes an inviting centerpiece for any meal.

The combination of textures—from tender chicken to crunchy broccoli—offers a delightful eating experience that is both satisfying and nutritious.

One Sunday, I doubled the recipe for a church potluck. It disappeared so quickly that I barely managed to grab a serving for myself before the dish was scraped clean.

A Cheesy Delight

At the heart of this dish is a rich, creamy cheese sauce that binds the ingredients together.

Melted cheddar cascades over the top, creating a golden layer that appeals to cheese lovers.

The addition of Parmesan cheese adds an extra depth of flavor, enhancing the overall taste and making each bite truly indulgent.

Meal Prep Made Easy

This casserole is ideal for meal prepping, allowing you to prepare a delicious dish that can be enjoyed throughout the week.

Simply make a batch on the weekend, portion it out, and store it in the refrigerator or freezer for quick meals later.

Reheating is a breeze, making it a convenient option for busy nights when time is tight.

I like to make individual portions in small foil pans, which freeze beautifully. This has been especially handy when we’ve had visiting mission teams—I can pull them from the freezer and reheat without fuss.

Perfect for Any Occasion

Whether it’s a family dinner, a potluck, or a cozy night in, this casserole fits the bill.

It’s a crowd-pleaser that appeals to both kids and adults alike, ensuring that everyone leaves the table satisfied.

The dish’s warm colors and inviting aroma add to the atmosphere, making any meal feel special.

Last Christmas Eve, we served this alongside a simple salad and garlic green beans. It was so comforting to enjoy familiar flavors while celebrating far from our extended family.

Customizable to Your Taste

This casserole serves as a fantastic base for customization.

Feel free to add your favorite vegetables or seasonings to personalize it.

Swap out chicken for turkey or introduce spices to cater to varied palates, ensuring this dish never gets boring.

One week when broccoli was scarce at the market, I swapped in green beans and a little spinach. My kids didn’t even notice the change, and the dish still had that same rich, cheesy flavor.

Garnishing for Presentation

For an extra touch, garnishing with fresh parsley or other herbs adds a pop of color.

A simple sprig can elevate the dish’s presentation and provide a hint of freshness.

Pair it with a side salad or crusty bread for a complete meal that delights the senses.

Cook and Prep Times

• Prep Time: 10 minutes
• Cook Time: 30 minutes
• Total Time: 40 minutes

Pro Tips

1. Steam broccoli lightly before baking so it keeps its bright color and tender-crisp texture.
2. Shred your own cheddar from a block—pre-shredded cheese often contains anti-caking agents that affect melting.
3. Let cream cheese soften at room temperature for smoother mixing.
4. Use rotisserie chicken to cut prep time in half without sacrificing flavor.
5. For a crisp topping, broil the casserole for the last 2–3 minutes of baking.

Ingredient Substitutions

• Broccoli → cauliflower florets or green beans
• Heavy cream → full-fat coconut milk for dairy-free option
• Cheddar cheese → Monterey Jack or mozzarella for a milder flavor
• Parmesan cheese → grated Romano or Asiago
• Chicken → cooked turkey or leftover roast pork

Tip from Grammie Shirley

If your casserole comes out watery, let it rest for 10 minutes before serving so the sauce can thicken and settle.
