How this casserole became a weeknight staple
Back when I was juggling job sites during the day and taste tests by night, I had one goal: come home to a dish that made me feel grounded. One night, armed with a rotisserie chicken, leftover potatoes, and some broccoli that was almost past its prime, I threw everything into a pan, crossed my fingers, and baked it. What came out of the oven surprised me it wasn’t just dinner, it was comfort. I scribbled the measurements on a napkin (classic me), tweaked it over time, and now it’s one of the most-requested dinners in my house.
This Chicken Potato Broccoli Casserole is packed with all the cozy feels. The creamy sauce soaks into the roasted potatoes. The broccoli adds bite. The chicken makes it hearty enough for a full meal. Whether it’s your first time making it or your fiftieth, this casserole earns its spot in your weekly rotation.

What makes this casserole so crave-worthy
It’s not just the blend of chicken, potato, and broccoli it’s how each part supports the other. The buttery roux (that’s your butter-flour base) thickens into a velvety sauce with milk and broth, coating every bite with rich cheddar flavor. Adding a topping of crispy panko and Parmesan gives you that golden crunch that takes this dish from good to unforgettable.
You don’t need fancy tools or ingredients. This is a dish you can make with kitchen staples. And if you’re feeling inspired, the Million Dollar Chicken Casserole is another recipe that takes simple ingredients and turns them into something spectacular.
Step-by-Step Guide to Making Chicken Potato Broccoli Casserole
Ingredient list with accurate measurements and tips
Below is the detailed list of what you’ll need to create the perfect Chicken Potato Broccoli Casserole:
- 2 cups cooked shredded chicken breast – Rotisserie chicken is ideal for flavor and ease
- 3 medium russet potatoes, peeled and diced into small cubes
- 2 cups fresh broccoli florets – Frozen works too (thawed and drained)
- 1 small yellow onion, finely chopped
- 2 cloves garlic, minced
- 1 tablespoon olive oil – For sautéing aromatics
- 2 tablespoons unsalted butter – Base of your roux
- 2 tablespoons all-purpose flour – Thickener for the creamy sauce
- 1½ cups whole milk – Adds richness to the sauce
- ½ cup chicken broth – Boosts the savory depth
- 1 cup shredded sharp cheddar cheese – Bold flavor; feel free to mix in Gruyère
- ½ teaspoon dried thyme – Earthy herbal note
- ¼ teaspoon paprika – Adds color and subtle warmth
- ½ cup panko breadcrumbs – For a crunchy topping
- ¼ cup grated Parmesan cheese – Umami-rich topper
- 1 tablespoon melted butter – Mixed into the breadcrumb topping
Step-by-step cooking instructions with practical tips
- Preheat the oven to 375°F (190°C).
- Boil the diced potatoes in salted water for 8–10 minutes until fork-tender. Drain and set aside.
- Steam or microwave the broccoli until just tender but still vibrant green. Drain and pat dry.
- Sauté the aromatics: In a large skillet over medium heat, add olive oil. Sauté chopped onion until soft (3–4 minutes). Add garlic and cook for 1 minute more.
- Make the roux: Push the aromatics to one side, melt butter in the same skillet, and stir in the flour to make a paste. Cook for 1–2 minutes to eliminate the raw flour taste.
- Create the sauce: Slowly whisk in milk and broth. Simmer and stir until thickened (3–4 minutes). Season with thyme, paprika, salt, and pepper.
- Melt in cheese: Stir in cheddar until melted and smooth.
- Combine the filling: In a large bowl or casserole dish, mix chicken, potatoes, broccoli, and sauce until fully coated.
- Assemble topping: Mix panko, Parmesan, and melted butter. Sprinkle evenly over the casserole.
- Bake for 20–25 minutes until bubbly and golden brown on top. Let rest 5 minutes before serving.

Best ways to serve and elevate Chicken Potato Broccoli Casserole
Chicken Potato Broccoli Casserole is pure comfort in a dish but that doesn’t mean it can’t be dressed up. I like to serve it straight from the baking dish, family-style, with big spoons and warm plates ready. On weekdays, I’ll pair it with a lightly dressed arugula salad or roasted carrots for a quick and balanced dinner. For a casual brunch twist, slice it into squares and serve alongside scrambled eggs and fruit salad. Trust me it holds up beautifully on a brunch buffet and makes your morning feel extra cozy.
When I want to impress guests without fussing too much, I’ll top each serving with a dollop of sour cream or drizzle of hot sauce. A sprinkle of green onions adds color and a bit of bite. And if you’re hosting, offer it with this Gluten-Free Bread on the side perfect for scooping up every last bit of creamy goodness.
Looking for something equally delicious but with a lighter Mediterranean vibe? These Lemon Dill Chicken Bowls are a fresh take on mealtime comfort.
Make-ahead and storage tips with a personal touch
This casserole is a lifesaver when I need a stress-free Sunday. I’ll often prep my Chicken Potato Broccoli Casserole the night before and stash it in the fridge, covered tightly. Come morning, I just top it with panko and Parmesan and slide it into the oven while I brew coffee. It makes weekend brunches feel indulgent but effortless and it’s a hit with family who wake up hungry.
Leftovers reheat beautifully. Store them in an airtight container in the fridge for up to 4 days. You can reheat individual portions in the microwave, or warm a larger batch in the oven at 350°F for 15–20 minutes until it’s bubbly again. Want to freeze it? Assemble it all except the topping, wrap tightly, and freeze for up to 2 months. Add the topping right before baking for best results.
This make-ahead flexibility reminds me of why I also love dishes like the Chicken Drumsticks Recipes they’re simple, reliable, and always crowd-pleasers.

FAQs: Chicken Potato Broccoli Casserole
Absolutely. Just make sure to thaw it fully and drain well to avoid excess moisture. You can even pat it dry with a paper towel to ensure your casserole stays creamy—not watery.
Cooked, shredded chicken breast works best. Rotisserie chicken is a favorite because it’s already seasoned, juicy, and saves prep time.
Yes! Sweet potatoes add a delicious hint of sweetness and extra nutrients. Cut them smaller than russets and consider roasting them slightly before adding to avoid mushiness.
Simply omit the chicken and use vegetable broth instead of chicken broth. You can add white beans, lentils, or sautéed mushrooms for extra substance and flavor.
