- 1 cup shredded cheddar cheese
- 1/2 cup sour cream
- 1/4 cup milk

How to Make this Cheesy Chicken Potato Broccoli Casserole
Getting your oven nice and hot before you start assembling the casserole guarantees even cooking and that perfect golden cheese topping. I always turn on the oven first thing—nothing worse than having everything ready to bake and then waiting for the oven to heat up.
Step 2: Par-boil 3 Cups of Diced Potatoes
Chop your potatoes into bite-sized cubes and boil them for about 5-7 minutes until they’re just fork-tender but not falling apart. This partial cooking gives them a head start before they go into the casserole.
Step 3: Blanch 2 Cups of Broccoli Florets
Drop your broccoli into boiling water for just 2 minutes, then immediately transfer to ice water to stop the cooking process. This keeps the broccoli bright green and prevents it from turning mushy during baking.
Step 4: Prepare the Creamy Sauce
In a bowl, combine 1/2 cup sour cream, 1/4 cup milk, 2 tablespoons melted butter, 1 teaspoon garlic powder, and salt and pepper to taste. Mix until smooth and creamy—this sauce is what brings everything together with rich, savory goodness.
Step 5: Layer the Ingredients in a Baking Dish
Start with the par-boiled potatoes on the bottom, then add 2 cups of diced cooked chicken, and top with the blanched broccoli florets. Creating layers helps guarantee every bite has a good mix of flavors. Using a premium baking dish will ensure even heat distribution and beautiful presentation when serving this casserole.
Step 6: Pour the Sauce and Add Cheese
Pour your creamy sauce evenly over all the ingredients, making sure to get into the corners. Then sprinkle 1 cup of shredded cheddar cheese all over the top—feel free to add a bit more if you’re a cheese lover like me.
Step 7: Bake Until Golden and Bubbly
Pop your casserole into the preheated oven and bake for 25-30 minutes, or until the cheese is melted and starting to brown, and everything is hot and bubbly throughout. The smell wafting through your kitchen will be absolutely mouthwatering.
Step 8: Add Optional Bacon Topping
For an extra special touch, sprinkle some crispy bacon bits over the top of your finished casserole just before serving. This adds a wonderful smoky crunch that contrasts beautifully with the creamy, cheesy goodness beneath.
What to Serve with Cheesy Chicken Potato Broccoli Casserole
This hearty casserole practically counts as a complete meal on its own, but a few simple sides can round things out perfectly. A crisp green salad with a tangy vinaigrette cuts through the richness beautifully—I’m partial to arugula with lemon dressing myself. Warm dinner rolls or garlic bread make excellent companions for sopping up that creamy sauce. For a lighter dinner, try some roasted cherry tomatoes that burst with sweetness alongside the savory casserole.
To drink, a cold glass of unsweetened iced tea or a light white wine works wonders. And don’t forget that drizzle of hot sauce on the side for those who like a little heat with their comfort food!
Cheesy Chicken Potato Broccoli Casserole Substitutions and Variations
This casserole is wonderfully adaptable to what you have on hand! Try these simple swaps and creative twists:
- Protein Options: Use leftover turkey, ham, or rotisserie chicken. For meatless versions, substitute chickpeas or white beans.
- Veggie Variations: Swap broccoli for cauliflower, Brussels sprouts, or peas. Add mushrooms or bell peppers for extra flavor and nutrition.
- Dairy Alternatives: Dairy-free? Use coconut milk and plant-based cheese. Greek yogurt works beautifully in place of sour cream.
- Potato Swaps: Sweet potatoes add a lovely color and nutritional boost. For lower-carb, try using cauliflower florets instead.
- Flavor Boosters: Stir in ranch seasoning, Italian herbs, or a spoonful of Dijon mustard. A dash of smoked paprika gives wonderful depth.
- Topping Ideas: Besides bacon, try crispy fried onions, buttered breadcrumbs, or crushed potato chips for that irresistible crunch factor.
Leftovers and Storage for this Cheesy Chicken Potato Broccoli Casserole
This hearty casserole keeps beautifully! Store leftovers in an airtight container in the refrigerator for up to 3-4 days. For longer storage, freeze individual portions for up to 2 months.
When reheating, add a splash of milk to prevent drying out. Cover with foil and warm in a 350°F oven for 15-20 minutes, or microwave on medium power with a damp paper towel over top.
Believe it or not, this casserole often tastes even better the next day after the flavors have had time to meld together. The texture might change slightly, with the potatoes absorbing more of the creamy sauce—many folks actually prefer it this way!
For meal prep, consider freezing the casserole unbaked, then thawing overnight before cooking.
