Ingredients You’ll Need

Before we jump into cooking, let’s talk about why each ingredient matters. Understanding the “why” makes cooking feel less stressful—and way more fun.

• Potatoes: Peeled and diced potatoes form the backbone of this casserole. Roasting them first is key—they turn crispy on the outside, fluffy inside, and soak up the creamy sauce like little sponges of comfort.
• Olive Oil: A light drizzle helps the potatoes roast evenly and adds a subtle richness without overpowering the dish.
• Salt: Simple but essential, salt seasons the potatoes and balances all the flavors so nothing tastes flat.
• Black Pepper: Freshly ground black pepper adds gentle warmth and rounds out the savory notes in the casserole.
• Cooked Chicken: Shredded or diced chicken brings protein and heartiness, turning this into a satisfying one-dish meal. Leftover roasted or rotisserie chicken works beautifully here.
• Butter: Melted with the chicken, butter adds richness and keeps the meat tender and flavorful.
• Fresh Broccoli Florets: Lightly steamed until tender-crisp, broccoli adds freshness, color, and a nutritious balance to the creamy elements.
• Sour Cream: This is where the creamy magic starts. Sour cream adds tang and keeps the sauce luscious without feeling too heavy.
• Milk: Milk loosens the sauce just enough so it coats every ingredient smoothly—no dry casserole bites here.
• Shredded Cheddar Cheese: Sharp cheddar brings bold flavor and that irresistible, melty cheese pull everyone loves.
• Grated Parmesan Cheese: Parmesan adds a salty, nutty finish and helps create a lightly crisp, golden topping.
• Garlic Powder: A pantry staple that adds savory depth without overpowering the dish.
• Onion Powder: Soft, aromatic onion flavor that blends seamlessly into the creamy sauce.
• Fresh Parsley: Chopped and sprinkled on at the end for a pop of freshness and color that brightens the whole dish.

How to Make Baked Potato Chicken and Broccoli Casserole (Step-by-Step)

This recipe is straightforward, and I promise—no culinary gymnastics required.

1. Preheat the Oven

Set your oven to 400°F (200°C). Starting with a hot oven helps the potatoes crisp up beautifully.

2. Season the Potatoes

In a large bowl, toss the diced potatoes with olive oil, salt, and black pepper. Make sure every piece gets coated.

3. Roast Until Golden

Spread the potatoes in a single layer on a baking sheet. Roast for 20–25 minutes, shaking the pan halfway through, until tender inside and golden on the edges.

4. Cook the Broccoli

While the potatoes roast, steam or boil the broccoli for 4–5 minutes until just tender. Drain very well—extra moisture is the enemy of a good casserole.

5. Warm the Chicken

In a saucepan over medium heat, melt the butter and add the cooked chicken. Stir until warmed through and lightly coated.

6. Make the Creamy Sauce

In a mixing bowl, whisk together sour cream, milk, garlic powder, onion powder, and half of the cheddar cheese until smooth.

7. Layer the Casserole

In a large casserole dish, start with the roasted potatoes. Add the chicken, then the broccoli, spreading everything evenly.

8. Add the Sauce

Pour the sour cream mixture over the top. Gently stir just enough to coat everything without turning it into a mushy mess.

9. Cheese It Up

Sprinkle the remaining cheddar cheese and the Parmesan evenly over the top.

10. Bake to Perfection

Lower the oven temperature to 350°F (175°C) and bake for 20–25 minutes, until the cheese is melted, bubbly, and lightly golden.

11. Rest (Yes, Really)

Let the casserole sit for 5 minutes before serving. This helps it set and makes serving easier.

12. Garnish & Serve

Finish with chopped fresh parsley and serve warm.

Helpful Cooking Tips (From My Real-Life Kitchen)

• Don’t skip roasting the potatoes. This step gives the casserole texture and prevents sogginess.
• Drain broccoli well. If you think it’s drained enough, give it one more shake.
• Use rotisserie chicken. Total time-saver on busy nights.
• Let it rest before serving. I know it’s tempting, but it really helps.

And if your cheese bubbles over a little? Congratulations—you did it right.
