👩🍳 How to Make Chicken Broccoli Potato Casserole
1. Preheat the oven:
Set your oven to 375°F (190°C) and grease a 9×13-inch baking dish.
2. Boil the potatoes:
In a large pot of salted water, boil cubed potatoes for 10 minutes, or until fork-tender. Drain and set aside.
3. Blanch the broccoli:
In the same pot, bring fresh water to a boil. Add broccoli florets and blanch for 3 minutes. Drain and set aside.
4. Mix the creamy base:
In a large mixing bowl, combine sour cream, milk, 1 cup of shredded cheese, garlic powder, onion powder, salt, and pepper. Stir until smooth.
5. Combine the filling:
Add the cooked chicken, potatoes, and broccoli to the bowl. Gently fold everything together until well-coated with the sauce.
6. Assemble the casserole:
Transfer the mixture to the prepared baking dish. Top with the remaining 1 cup of shredded cheese.
7. Add the crispy topping:
Mix breadcrumbs with melted butter in a small bowl, then sprinkle evenly over the top.
8. Bake:
Bake for 20–25 minutes, or until the casserole is bubbly and the top is golden brown.
9. Let it rest & serve:
Cool for 5 minutes before serving. Enjoy!
🧀 Helpful Tips & Variations
- Make it vegetarian: Skip the chicken and double up on broccoli or add sautéed mushrooms and spinach.
- Add heat: Mix in a pinch of red pepper flakes or a dash of hot sauce.
- Switch up the cheese: Try Monterey Jack, mozzarella, or even Gruyère for a different flavor twist.
- Gluten-free option: Use gluten-free breadcrumbs or omit them entirely for a cheesy crust only.
🍽️ What to Serve With It

- Garlic bread or dinner rolls
- Steamed green beans or roasted carrots

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through, or microwave individual portions.
