Ingredients
For the casserole:
- 2 pounds boneless, skinless chicken breasts
- 1½ pounds baby potatoes
- 3 cups broccoli florets
- 2 tablespoons olive oil
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- ½ teaspoon onion powder
- ½ teaspoon salt
- ½ teaspoon black pepper
- 1 cup chicken broth

- 4 ounces cream cheese, softened
- 1½ cups shredded cheddar cheese
- ½ cup shredded mozzarella cheese
- ¼ cup grated Parmesan cheese
- 2 cloves garlic, minced
- 2 tablespoons chopped fresh parsley
How to Make Chicken Broccoli Potato Casserole
Step 1: Prepare the Oven
Preheat the oven to 400°F (200°C).
Lightly grease a 9×13-inch baking dish.
Wash the potatoes thoroughly and cut them into small, evenly sized pieces.
Cut the chicken into bite-sized chunks.
Step 2: Season the Ingredients
Place the potatoes and chicken in a large bowl.
Add olive oil, garlic powder, paprika, onion powder, salt, and black pepper.
Toss until everything is evenly coated.
Spread the seasoned potatoes and chicken in the prepared baking dish.
Step 3: Start Baking
Bake the chicken and potatoes for approximately 25 minutes.
Starting the potatoes before adding the broccoli helps prevent the broccoli from becoming overly soft.
Step 4: Prepare the Creamy Sauce
While the casserole begins baking, prepare the sauce.
Add the chicken broth, heavy cream, cream cheese, and minced garlic to a saucepan over medium heat.
Whisk until the cream cheese melts and the sauce becomes smooth.
Stir in ½ cup of cheddar cheese and the Parmesan cheese.
Continue stirring until the cheese melts.
Avoid bringing the sauce to a rapid boil.
Step 5: Add the Broccoli
After the initial baking time, remove the casserole from the oven.
Add the broccoli florets and pour the creamy sauce evenly over the chicken and potatoes.
Gently stir to distribute the ingredients without breaking the potatoes apart.
Step 6: Add More Cheese
Sprinkle the remaining cheddar cheese and mozzarella over the top.
Return the casserole to the oven.
Bake for another 15–20 minutes, or until the potatoes are tender, the chicken is fully cooked, and the cheese is bubbling and golden.
For extra browning, you can place the casserole under the broiler for 1–2 minutes at the end. Watch it carefully.
Step 7: Rest and Serve
Allow the casserole to rest for approximately 5–10 minutes before serving.
Garnish with fresh parsley and serve warm.
Choosing the Best Potatoes
Small baby potatoes are convenient because they cook relatively quickly and have a creamy interior.
Yukon Gold potatoes are another excellent choice because they become tender and buttery when baked.
If using larger potatoes, cut them into small, evenly sized cubes so they cook at the same rate as the chicken.
Chicken Broccoli Cheese Casserole With Potatoes
A traditional chicken broccoli cheese casserole often uses pasta or rice as the main starch.
This version replaces those ingredients with potatoes.
The result is especially hearty, with creamy potatoes absorbing the flavorful sauce while the cheese forms a golden layer on top.
If you love cheesy chicken casseroles, this is an easy way to change up your usual recipe.
Chicken and Broccoli Casserole Variation
For a classic chicken and broccoli casserole, you can easily simplify this recipe.
Leave out the potatoes and increase the broccoli.
You can then serve the creamy chicken and broccoli mixture over rice, cauliflower rice, or another favorite side.
This makes the recipe flexible enough to suit different dinner preferences.
What About Chicken Broccoli Pasta?
If you love chicken broccoli pasta, this casserole can be adapted into a pasta version.
Cook approximately 12 ounces of penne or rotini according to the package directions.
Replace the potatoes with the cooked pasta and reduce the baking time because the pasta is already cooked.
The same creamy garlic cheese sauce works beautifully with pasta, chicken, and broccoli.
Tips for the Best Casserole
Cut Everything Evenly
Keep the chicken and potatoes similar in size so they cook evenly.
Don’t Add Broccoli Too Early
Adding broccoli later helps it stay bright and slightly crisp instead of becoming mushy.
Use Freshly Shredded Cheese
Freshly shredded cheese usually melts more smoothly than pre-shredded varieties.
Check the Chicken
Chicken should be fully cooked before serving. Use a food thermometer to verify that the thickest pieces reach 165°F (74°C).
Let It Rest
A short resting period allows the sauce to thicken slightly and makes the casserole easier to serve.
Easy Variations
Add sliced mushrooms for extra savory flavor.
Use Monterey Jack or Colby cheese instead of cheddar.
Use cauliflower alongside the broccoli for extra vegetables.
Add a pinch of red pepper flakes for a little heat.
Make-Ahead Instructions
You can prepare the casserole earlier in the day.
Assemble the chicken, potatoes, broccoli, sauce, and cheese in the baking dish, cover tightly, and refrigerate.
When ready to bake, allow the dish to sit at room temperature briefly while the oven preheats.
Because the casserole starts cold, you may need to add several minutes to the baking time.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days.
Reheat individual servings in the microwave until hot.
For larger portions, cover the casserole with foil and warm it in a 350°F oven.
Frequently Asked Questions
Can I use chicken thighs?
Yes. Boneless, skinless chicken thighs work well and can provide a particularly juicy result.
Can I use frozen broccoli?
Yes. Thaw and drain frozen broccoli before adding it to prevent excess moisture.
Can I use different cheese?
Absolutely. Cheddar, mozzarella, Monterey Jack, Colby, and Parmesan all work well.
Can I make this without cream?
You can replace some of the cream with additional chicken broth and milk, although the sauce will be lighter.
Can I add pasta?
Yes. Replace the potatoes with cooked pasta to create a creamy chicken broccoli pasta casserole.
