Ingredients in Chicken Broccoli Potato Casserole

Casserole Ingredients

Broccoli – You will need 4 cups of broccoli, cut into small pieces.

Olive oil – Just a little bit of olive oil is needed for cooking the onions. You can use a different kind of oil if you prefer – avocado oil works great too!

Onion: Yellow onion works best in this dish. I always buy diced onions from the frozen section in the grocery store and keep them stocked up so that I can use them for recipes like this one. I haven’t chopped an onion in years!

Salt, pepper, Italian seasoning, paprika – These simple seasonings add a lot of flavor to the casserole.

Chicken – You will need 2-3 boneless, skinless chicken breasts, cut into bite-sized pieces. If you have frozen chicken, make sure to completely thaw it before adding it to the recipe.

Garlic – Garlic adds a lot of flavor to the recipe. You can mince 3 cloves of garlic, or you can use 1 1/2 teaspoons of minced garlic from a jar. I always keep a jar in my fridge to save a few minutes on recipes like this one.

Potatoes – Gold potatoes work the best for this recipe, but you can use red potatoes or Russet potatoes if you prefer. Peel and dice the potatoes into small cubes before adding to the recipe.

Cheese – Shredded cheddar and grated parmesan are sprinkled on the top of the casserole while baking.

Ingredients in simple cream sauce recipe.

Sauce ingredients

Butter – Real butter works best.

Flour – Use ¼ cup of all-purpose flour to thicken the sauce for the casserole.

Chicken broth – The sauce is flavored with 2 cups of chicken broth.

Heavy cream – A cup of heavy cream adds a lot of richness to the cream sauce. You can use milk if you prefer, but the sauce won’t be quite as thick.

Garlic powder – Just a teaspoon of garlic powder adds a lot of flavor to the sauce.

Salt and pepper to taste

Chicken, potatoes, broccoli, and cheese.

How to make Chicken Broccoli Potato Casserole

Preheat the oven to 375°F. Grease a 9×13-inch baking dish with cooking spray and set it aside.

Blanch the broccoli by boiling it in salted water for 2-3 minutes until bright green and slightly tender. Drain and immediately rinse under cold water. Set aside.

In a large skillet, heat the olive oil over medium heat. Add the chopped onions, sautéing until they become translucent and fragrant.

COOK THE CHICKEN

Season the chicken with salt and pepper to taste, Italian seasoning, and paprika. Add the chicken pieces to the skillet and cook until they are no longer pink in the center, about 5-7 minutes. Remove the cooked chicken from the skillet and set it aside (leave the onion in the pan). Add the minced garlic and cook for 1 minute.

MAKE THE SAUCE

Add flour to butter and onions to make sauce.

In the same skillet with the onion and garlic, melt the butter over medium heat. Once the butter is melted, whisk in the flour to create a roux. Cook the roux for 2-3 minutes, stirring constantly until it turns a light golden color.

Slowly pour in the chicken broth while continuing to whisk the mixture.

Once the broth is fully incorporated, add the heavy cream. Bring the sauce to a simmer, and let it cook for a few minutes until it thickens. Season the sauce with garlic powder, then salt and pepper to taste.

ASSEMBLE THE CASSEROLE

Mixing sauce with potatoes, broccoli, and chicken.

In a large mixing bowl, combine the blanched broccoli florets and diced potatoes. Season with salt and pepper to taste; mix well. Add the cooked chicken and mix. Pour the creamy sauce over the mixture and gently stir to combine, ensuring that everything is evenly coated.

Transfer the mixture to the prepared baking dish. Sprinkle shredded cheddar cheese and grated Parmesan cheese over the top.

BAKE & SERVE

Cover the baking dish with aluminum foil and bake for 25-30 minutes. Then, remove the foil and bake for an additional 10-15 minutes or until the top is golden brown, and the casserole is bubbling. Be careful not to overcook the casserole. Once the top is golden and the casserole is bubbling, it’s ready. Overcooking can make the chicken and vegetables too soft.

Allow the casserole to cool for a few minutes before serving. Enjoy your creamy chicken, broccoli, and potato casserole as a comforting and hearty meal!
