About the Ingredients
Cooked Chicken
Cooked shredded or diced chicken adds protein and makes prep quick. Rotisserie chicken is a great shortcut.
Broccoli Florets
Bring color, crunch, and nutrients; fresh or thawed frozen broccoli both work.
Onion
Diced onion adds savory depth and richness to the casserole’s flavor base.
Garlic
Minced garlic enhances the savory flavor profile and adds aromatic depth.
Shredded Cheddar Cheese
Melts into a bubbly, golden topping; sharp cheddar gives the most flavor.
Sour Cream
Gives the sauce creamy tang and blends smoothly with the cheese and chicken.
Heavy Cream or Milk
Heavy cream makes the sauce rich and velvety; milk offers a lighter creamy option.
Butter
Helps create a smooth sauce and adds richness to the dish.
Paprika
Adds a mild heat and a deep, earthy flavor to the sauce.
Garlic Powder
Enhances the garlic flavor and provides a subtle warmth.
Salt and Pepper
Essential for seasoning and bringing out the flavors of all the ingredients.
Fresh Chives or Parsley
Add freshness and a pop of color on top.
Tips & Tricks
Evenly Dice Potatoes
Ensure the potatoes are diced evenly to guarantee they cook at the same rate.
Par-Cook for Softer Potatoes
If you prefer softer potatoes, par-cook them for 5 minutes before combining with other ingredients.
Cheese Placement
Mix the cheese into the casserole or leave it on top depending on how melty you want the finish.
Pro Tips
- Use heavy cream for a richer sauce, or milk for a lighter option.
- Cover the casserole with foil for the first 20 minutes to prevent over-browning.
- Let the casserole rest for 10 minutes before serving so it sets properly.
Step-by-Step Instructions
Preheat and Prepare
Preheat your oven to 375°F (190°C) and grease a 9×13 baking dish to prevent sticking and ensure easy cleanup.
Combine Ingredients
In a large bowl, combine the cooked chicken, diced potatoes, broccoli florets, onion, and minced garlic, ensuring everything is evenly distributed.
Create the Sauce
Melt the butter in a saucepan over medium heat. Add the sour cream, heavy cream or milk, paprika, garlic powder, salt, and pepper. Stir until the mixture is smooth and well combined.
Mix and Transfer
Pour the creamy sauce over the chicken mixture and toss until everything is evenly coated. Transfer the mixture to the prepared baking dish and spread it out evenly.
Top with Cheese
Sprinkle the shredded cheddar cheese over the top of the casserole, ensuring it covers the entire surface for a cheesy finish.
Bake to Perfection
Bake the casserole for 40–45 minutes until it is bubbly and golden. If desired, broil for an additional 2–3 minutes for a crispy top.
Rest and Garnish
Remove from the oven and allow to rest briefly before garnishing with fresh chives or parsley. Serve hot for the best flavor.
Delicious Variations
Add Bacon or Ham
For extra flavor, incorporate cooked bacon or ham into the casserole for a smoky twist.
Vegetable Swap
Replace broccoli with cauliflower, green beans, or mixed vegetables for a different nutritional profile.
Cheese Alternatives
Use Monterey Jack or mozzarella in place of cheddar for a unique cheese flavor.
