Why You’ll Love This Chicken Potato Broccoli Casserole

This casserole is the definition of comfort food made easy. It uses simple, pantry-friendly ingredients and comes together with minimal prep. Plus, it’s easy to customize—swap in different cheeses or add in bacon bits or herbs for extra flair. It reheats like a dream and can easily be made ahead and baked when ready. It also happens to be kid-friendly and great for picky eaters thanks to its creamy, cheesy texture.

Can I Use Frozen Broccoli for This Casserole?

Yes, you can! If you don’t have fresh broccoli on hand, frozen broccoli florets work just fine. Just make sure to thaw and drain them well before mixing into the casserole to avoid excess moisture. You can even steam them briefly to ensure they’re tender but not mushy before baking.

Ingredients for the Chicken Potato Broccoli Casserole

This recipe keeps things simple but flavorful. Each ingredient plays an important role in creating a rich, hearty casserole that holds together beautifully and satisfies with every bite.

• Chicken breast
• Russet potatoes
• Broccoli florets
• Cheddar cheese
• Cream of chicken soup
• Sour cream
• Garlic powder
• Onion powder
• Salt and pepper
• Olive oil

The chicken breast adds lean protein that pairs perfectly with the creamy base. Russet potatoes provide a sturdy, filling layer that soaks up flavor. Broccoli florets bring color, texture, and a touch of green to balance things out. Cheddar cheese melts into gooey perfection, making every bite irresistible. Cream of chicken soup and sour cream create a rich, savory sauce, while garlic powder, onion powder, salt, and pepper season the entire dish. A drizzle of olive oil helps roast the potatoes and adds depth.

How To Make the Chicken Potato Broccoli Casserole

Step 1: Prep the Ingredients

Peel and dice the potatoes into small cubes and toss them in olive oil, salt, and pepper. Roast them at 400°F for about 25 minutes until golden and slightly crispy.

Step 2: Cook the Chicken

While the potatoes are roasting, dice the chicken breast and cook it in a skillet over medium heat until golden and cooked through. Season with garlic and onion powder.

Step 3: Steam the Broccoli

Lightly steam the broccoli florets until bright green and just tender. Don’t overcook them since they’ll continue cooking in the oven.

Step 4: Mix the Casserole

In a large bowl, combine the cooked potatoes, chicken, broccoli, cream of chicken soup, sour cream, and half the cheddar cheese. Mix everything well.

Step 5: Bake It Up

Pour the mixture into a greased casserole dish. Top with the remaining cheddar cheese and bake at 375°F for 20-25 minutes or until bubbly and golden.

How to Serve and Store This Cozy Casserole

This casserole is best served warm, right out of the oven when the cheese is melted and golden. It feeds about 6 people generously, making it a great option for family dinners or small gatherings.

To store leftovers, let the casserole cool completely before transferring it to an airtight container. It will keep in the refrigerator for up to 4 days. To reheat, simply pop a portion in the microwave or warm it in the oven at 350°F until heated through.

You can also freeze portions for longer storage. Wrap individual servings in foil and place them in freezer-safe bags. When ready to eat, thaw overnight in the fridge and bake until hot.
