Ingredients Notes

This recipe comes together with a handful of pantry staples and fresh ingredients. Here’s what you need:
- Russet Potatoes – These are the best choice because they hold their shape while still becoming soft and fluffy when baked. You can also use Yukon Golds for a creamier texture.
- Chicken Breast – Boneless, skinless chicken breasts work well, but you can also use chicken thighs for extra juiciness. Have leftover rotisserie chicken? That works too!
- Broccoli – Fresh broccoli florets add a pop of color and nutrition. If you only have frozen broccoli, just thaw and pat dry before adding it in.
- Cheddar Cheese – Sharp cheddar gives this casserole bold, cheesy flavor. You can also mix in mozzarella, Monterey Jack, or even Parmesan for extra depth.
- Sour Cream & Milk – This combo creates a creamy, luscious texture without making the casserole too heavy. Greek yogurt is a great substitute if you want a healthier option.
- Garlic & Onion Powder – These simple seasonings add depth and warmth to every bite.
- Butter & Olive Oil – Used for roasting the potatoes and adding richness to the dish.
Equipment Needed:
- A 9x13-inch baking dish
- A large mixing bowl
- A sharp knife for dicing potatoes and chicken
How To Make This Baked Potato Chicken and Broccoli Casserole

Making this cheesy, comforting casserole is as simple as roasting, mixing, and baking! Let’s break it down step by step.
1. Roast the Potatoes
Start by preheating your oven to 400°F (200°C). Dice your russet potatoes into bite-sized cubes, toss them with olive oil, garlic powder, onion powder, salt, and pepper, and spread them out on a baking sheet. Roast for 20 minutes until golden and fork-tender.
2. Cook the Chicken
While the potatoes are roasting, cut your chicken breast into small cubes. In a skillet, heat butter over medium heat and cook the chicken for 5-7 minutes, or until no longer pink. Set aside.
3. Steam the Broccoli
Blanch or steam your broccoli florets for just 2-3 minutes to keep them bright green and slightly crisp.
4. Mix Everything Together
In a large bowl, combine the roasted potatoes, cooked chicken, and broccoli. Add sour cream, milk, and half of the shredded cheese. Stir everything together until well coated.
5. Bake to Perfection
Transfer the mixture into a greased 9x13-inch baking dish and sprinkle the rest of the cheddar cheese over the top. Bake uncovered for 15-20 minutes, until the cheese is melted and bubbly.
6. Serve and Enjoy!
Let the casserole rest for 5 minutes before serving. Garnish with fresh parsley or green onions for a pop of freshness!
Storage Options
If you have leftovers (which isn’t always guaranteed!), here’s how to store them:
- In the Fridge: Store in an airtight container for up to 4 days. Simply reheat in the microwave or oven.
- In the Freezer: Freeze portions in freezer-safe containers for up to 3 months. Thaw in the fridge overnight before reheating.
- Reheating: Warm up in the oven at 350°F (175°C) for 15 minutes, or microwave in 30-second bursts until heated through.
Variations and Substitutions
One of the best things about this casserole is how easy it is to customize! Here are some tasty variations:
1. Swap the Protein
Not a fan of chicken? Use turkey, ground beef, or even ham for a different twist.
2. Go Low-Carb
Skip the potatoes and use cauliflower florets instead for a lighter, keto-friendly version.
3. Add More Veggies
Throw in mushrooms, bell peppers, or spinach to pack in even more nutrients.
4. Spice It Up
Love a little heat? Add red pepper flakes, cayenne, or even diced jalapeños for a spicy kick.
5. Try Different Cheeses
Experiment with Gouda, Pepper Jack, or Swiss cheese to change up the flavor profile.
No matter how you customize it, this Baked Potato Chicken and Broccoli Casserole is guaranteed to be delicious and satisfying.
