Ingredients Needed to Make Chicken Potato Broccoli Casserole

Let’s talk about what makes this Chicken Potato Broccoli Casserole truly shine. The magic here lies in everyday ingredients that come together in the most comforting, can’t-wait-for-seconds kind of way. No weird stuff—just real, whole foods you probably already have in your fridge or pantry.

Here’s a breakdown of what you’ll need and why each ingredient earns its place in this delicious dinner recipe:

• 1.5 lbs boneless, skinless chicken breasts or thighs
  Whether you prefer white or dark meat, either will work beautifully. Diced into bite-sized pieces, the chicken becomes juicy and tender as it bakes. Thighs offer a bit more flavor and richness, while breasts are leaner.

• 3 cups Yukon Gold or Russet potatoes, diced
  These starchy heroes soak up the buttery, cheesy broth and bake into soft, golden perfection. Leave the skin on for added fiber, flavor, and a rustic vibe. Yukon Golds are creamy and hold their shape well, while Russets bring a fluffier bite.
• 3 cups fresh broccoli florets
  Broccoli adds color, crunch, and a nice balance to the heavier ingredients. Fresh is best for texture, but if frozen broccoli is what you’ve got, just thaw and pat it dry before tossing it in.

• 2 cups sharp cheddar cheese, shredded
  Cheese is where the comfort really kicks in. Sharp cheddar gives that bold, tangy depth and turns melty in all the right places. You could mix it up with mozzarella for stretch or Gruyère for nuttiness, but honestly, cheddar nails it.
• ¾ cup low-sodium chicken broth
  This keeps everything moist and flavorful without making it soupy. The low-sodium version is ideal so you can control the saltiness yourself. Homemade or store-bought both work—just pour, mix, and move on.
• 4 tablespoons unsalted butter, melted
  Butter brings richness and helps the potatoes get a little caramelized around the edges. If you’re watching dairy or want a lighter version, you can reduce the amount—but let’s be honest, butter makes it better.
• 1 teaspoon garlic powder
  Garlic powder adds a mellow, savory depth without the need to sauté anything. It’s a weeknight shortcut with big payoff.
• ½ teaspoon salt (or to taste)
  Just enough to bring out the flavors without overpowering the dish. You can always add a little more before serving if needed.
• ¼ teaspoon black pepper
  A little pepper keeps things from falling flat. It doesn’t make the dish spicy—just nicely seasoned.
• ½ teaspoon paprika or onion powder (optional but recommended)
  This adds a subtle warmth or a hint of onion flavor. Totally up to you, but even just a pinch goes a long way in boosting overall taste.

These simple, everyday ingredients come together to create a chicken potato broccoli casserole that’s creamy, hearty, and loaded with flavor in every single forkful. And don’t worry—if you need to make swaps (like sweet potatoes for a fall twist or rotisserie chicken to save time), this recipe is flexible enough to handle it.

Instructions to Make Chicken Potato Broccoli Casserole

If you’ve got 15 minutes of prep and a little oven time, then you’ve got dinner handled. This chicken potato broccoli casserole recipe is simple enough for busy weeknights but tasty enough to serve to guests or picky family members. Here’s exactly how to pull it off—from fridge to fork.

Step 1: Preheat Your Oven

Start by preheating your oven to 375°F (190°C). Getting the oven hot before the casserole goes in ensures even cooking and that crispy, golden cheese top we’re all after. Don’t skip this step—this isn’t a microwave meal!

Tip: Place the oven rack in the center position. This helps your casserole cook evenly without burning the top or undercooking the middle.

Step 2: Chop the Ingredients

While the oven’s heating, grab your cutting board and start chopping:

• Dice the chicken into 1-inch cubes. Whether you’re using breasts or thighs, make sure the pieces are roughly the same size for even cooking.
• Dice your potatoes (Yukon Gold or Russet) into small, bite-sized chunks. No need to peel unless you want to—leaving the skin adds flavor and nutrients.
• Chop your broccoli into small florets. If using frozen, thaw first and blot with a paper towel to avoid excess moisture.

Short on time? You can substitute with rotisserie chicken for even quicker prep—just reduce the cook time by about 10 minutes. For another fast chicken dinner, check out our Cheesy Baked Chicken Fajita Casserole.

Step 3: Combine in a Mixing Bowl

In a large mixing bowl, toss in your prepared chicken, potatoes, and broccoli. Then add the flavor-boosting ingredients:

• 2 cups shredded sharp cheddar cheese
• ¾ cup low-sodium chicken broth
• 4 tablespoons melted butter
• 1 teaspoon garlic powder
• ½ teaspoon salt
• ¼ teaspoon black pepper
• Optional: ½ teaspoon paprika or onion powder for extra depth

Stir everything together until the ingredients are evenly coated and well combined. You’re building layers of flavor here—don’t rush it.

Make it your own: Feel free to add a pinch of red pepper flakes for a subtle kick or toss in some cooked bacon bits for smoky richness. If you’re feeling bold, our Spicy Buffalo Chicken Pasta Bake brings the heat in a similar casserole format.

Step 4: Transfer to a Casserole Dish

Lightly grease a 9×13-inch casserole dish with non-stick spray, olive oil, or a bit of butter. Then pour in your chicken-potato-broccoli mixture and spread it out evenly using a spatula.

Make sure the ingredients are distributed in a single, even layer. This helps everything cook at the same pace and allows the top to crisp up beautifully.

Step 5: Cover and Bake

Cover the dish tightly with foil—this step is key! The foil traps steam inside the dish and helps your chicken cook through while keeping the potatoes tender.

Pop the dish into your preheated oven and bake for 45 minutes.

Why cover it? Without foil, the cheese and top layer may brown too quickly while the potatoes remain undercooked. Keep it covered now—we’ll uncover it soon for that golden finish.

Step 6: Uncover and Finish Baking

After 45 minutes, carefully remove the foil (watch for steam!) and return the dish to the oven.

Continue baking uncovered for another 15 minutes, or until:

• The potatoes are fork-tender
• The chicken is fully cooked (internal temp 165°F)
• The top is golden, bubbling, and irresistibly cheesy

If you like your casserole with a crispy edge, you can broil it for the last 2–3 minutes. Just keep a close eye—cheese goes from melty to scorched in seconds.

Step 7: Let It Rest, Then Serve

This step is just as important as the rest: Let your chicken potato broccoli casserole rest for 5–10 minutes after taking it out of the oven.

Why? This allows the sauce to thicken slightly, flavors to settle, and makes it easier to slice and serve without everything sliding apart.

Scoop into plates or bowls and serve warm. If you’ve got crusty bread, bring it on—it’s perfect for soaking up all that cheesy goodness.

Bonus Tip: Store leftovers in airtight containers. Reheat with a splash of chicken broth to restore creaminess. For more ideas on how to reheat casseroles like a pro, check out our section on Storage and Reheating Tips below.
