Ingredients You’ll Need
The ingredients for this casserole are refreshingly simple, but each one plays a huge role in building flavor, creaminess, and that irresistibly golden cheese topping. Here’s what you’ll gather for your Baked Potato Chicken and Broccoli Casserole adventure:
- Russet potatoes: Choose starchy potatoes for the perfect fluffy, hearty base—peeled, cooked, and cubed.
- Cooked and shredded chicken breast: Use rotisserie chicken for ease, or your favorite seasoned baked chicken—tear it up for those cozy bites.
- Broccoli florets: Lightly steamed or blanched so they keep a hint of crispness and gorgeous green color.
- Sour cream: This is your creamy hero; swap in Greek yogurt if you want to lighten things up.
- Mayonnaise: Adds that extra tang and “can’t quite put your finger on it” richness to the sauce.
- Shredded cheddar cheese: Go for sharp or medium; it melts into gooey ribbons and layers every bite with deep, cheesy flavor.
- Grated Parmesan cheese: Brings another dimension of cheesy depth and a lovely golden finish on top.
- Garlic powder: Infuses gentle, savory warmth without overwhelming the other flavors.
- Onion powder: Balances the garlic and gives that subtle, classic casserole undertone.
- Salt and black pepper: Necessary for bringing out all the best in your starring ingredients.
- Smoked paprika (optional): A dash adds color and a hint of smoky intrigue—totally optional, but a fun twist!
- Chopped green onions (optional): For a fresh, punchy finish sprinkled on at the end.
- Extra shredded cheese for topping: Because when it comes to casseroles, more melty cheese is always better.
How to Make Baked Potato Chicken and Broccoli Casserole
Step 1: Prep Your Ingredients
Before you even think about assembling, set yourself up for smooth sailing. Cook your potatoes until just fork-tender, shred your chicken, and lightly steam or blanch the broccoli florets. You want the broccoli bright green and crisp, not mushy—it stays that way through baking. Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish, so nothing sticks and cleanup is a breeze.
Step 2: Mix Up the Creamy Sauce
Grab a mixing bowl and stir together the sour cream, mayonnaise, cheddar and Parmesan cheeses, garlic powder, onion powder, salt, pepper, and a sprinkle of smoked paprika if you’re feeling adventurous. This sauce is your flavor-packed glue, transforming the casserole from ordinary to unforgettable. Make sure everything is well combined for that signature luscious texture.
Step 3: Combine the Casserole Magic
In a large bowl, gently toss together the cooked potatoes, shredded chicken, and broccoli. Pour over the creamy cheese sauce and fold everything together—use a gentle hand so the potatoes don’t break apart. The result should be a hearty, colorful mixture where every chunk is coated in creamy goodness.
Step 4: Layer and Top
Spooning the mixture evenly into your prepared baking dish is somehow so satisfying, and don’t forget to scrape the bowl clean (no flavor left behind!). Sprinkle generously with extra shredded cheese—there’s no such thing as too much of that golden, bubbly top on a Baked Potato Chicken and Broccoli Casserole.
Step 5: Bake to Perfection
Pop your dish into the oven, uncovered, for 25 to 30 minutes. You want the casserole hot and bubbling, with spots of toasted cheese across the surface. Once out, let it cool for just a few minutes—it’ll set up a bit, making those hearty, cheesy scoops even more irresistible.
How to Serve Baked Potato Chicken and Broccoli Casserole

Garnishes
Finish off your Baked Potato Chicken and Broccoli Casserole with a flourish of chopped green onions for freshness and color, or a sprinkle of additional smoked paprika if you want a little pop. A handful of chopped chives or a dollop of sour cream works beautifully too—whatever pleases your crowd and adds a little special something on top.
Side Dishes
This casserole shines as a hearty main, but pairing it with a crisp green salad or a juicy tomato-cucumber salad cuts through the richness perfectly. Warm dinner rolls or a slice of crusty bread are also ideal for mopping up any creamy goodness left on your plate. Don’t forget a glass of something refreshing—iced tea or lemonade—and you’ve got the ultimate comfort meal.
Creative Ways to Present
Try spooning the casserole into individual ramekins for single-serve portions at a casual dinner party. If you’re meal-prepping, portion into glass containers for grab-and-go lunches that reheat like a dream. For brunch, top each serving with a poached egg for a decadent twist that’ll have everyone swooning. However you serve it, the bubbly layers and melty cheese are always show-stopping.
Make Ahead and Storage
Storing Leftovers
Let the casserole cool completely, then cover the dish tightly with foil or transfer portions into airtight containers. Baked Potato Chicken and Broccoli Casserole will keep well in the fridge for up to 3 days—just the thing for stress-free lunches or quick dinners.
Freezing
This casserole freezes beautifully! Assemble the casserole (but hold off on the final cheese layer), wrap it well, and freeze for up to 2 months. When ready to bake, thaw overnight in the fridge, sprinkle on the cheese, and pop it in the oven. It’s a lifesaver for busy weeks or unexpected guests.
Reheating
To reheat, cover with foil and warm in a 350°F (175°C) oven until hot and bubbly. For individual servings, a quick stint in the microwave (about 2-3 minutes, depending on your microwave) works great. If the casserole seems a bit dry, add a splash of milk or a dollop of sour cream before reheating to restore that creamy texture.
FAQs
Can I use rotisserie chicken in this casserole?
Absolutely! Rotisserie chicken is a fantastic shortcut that shaves time off prep and adds great flavor to your Baked Potato Chicken and Broccoli Casserole. Just shred it and mix it in as directed.
What can I substitute for sour cream?

Can I make this casserole ahead of time?
Yes, you can assemble the casserole up to a day in advance, cover tightly, and refrigerate until you’re ready to bake. This is ideal for entertaining or busy weeknights—just pop it in the oven when you need it.

Yes! As long as you double-check your packaged ingredients (most are naturally gluten-free), this recipe is perfect for gluten-free diets—no pesky bread crumbs or flour required.
Can I add extra veggies or bacon?
