To make this casserole, I started by chopping some broccoli florets, peeling and cubing some Yukon gold potatoes and cutting some boneless skinless chicken breasts into bite sized pieces.

I greased a 9 x 13 inch baking dish well with cooking spray and set it aside.

I blanched the broccoli in some boiling water and then immediately drained it and rinsed it with cold water.

I heated some olive oil in a large skillet over medium heat.

I added some chopped onion to the skillet.

I cooked the onions until they were translucent.

I seasoned the chicken pieces with salt, pepper, Italian seasoning and paprika.

I added the seasoned chicken pieces to the skillet.

I stirred and cooked the chicken pieces until they were cooked through.

Then I removed the cooked chicken from the skillet and set it aside.

I added some minced garlic to the skillet and cooked it for a minute.

I added some butter to the skillet.

Once the butter was melted I added some all purpose flour to the skillet.

I whisked the flour and melted butter together well to create a roux.

I continued cooking the roux until it browned slightly.

I slowly poured in the chicken broth with whisking continuously.

Then I added some heavy cream.

I brought the sauce to a simmer and continued to cook it until it thickened.

I seasoned the sauce with garlic powder, salt and pepper.

I dumped the blanched broccoli and cubed potatoes into a large mixing bowl.

I added the cooked chicken pieces to the bowl.

I added the creamy sauce to the bowl.

I stirred until all of the ingredients were well coated.

Then I transferred the mixture to the prepared baking dish.

I sprinkled shredded cheddar cheese and grated parmesan cheese on top.

I covered the baking dish with aluminum foil.

I placed the dish in the oven and baked the casserole, covered, for thirty minutes.

After thirty minutes I removed the foil and continued baking the casserole until it was bubbling and the top was golden brown.

I allowed the casserole to rest for a few minutes.

Then the cheesy chicken and potato casserole with broccoli was ready to serve.

The tender chicken pieces and potatoes are smothered in a creamy and flavourful sauce.

The vibrant broccoli florets bring a burst of color and freshness to the ensemble.

This fuss-free recipe combines everyday ingredients to create a delightful one-dish wonder that’s as easy to make as it is delicious to savor.

Ingredients You’ll Need to Make This Chicken Broccoli Potato Casserole:

• 4 cups broccoli florets, cut into small pieces
• 2 tablespoons olive oil
• ¾ cup onion, finely chopped
• Salt and pepper to taste
• 1 teaspoon Italian seasoning
• ½ teaspoon paprika
• 2-3 boneless, skinless chicken breasts, cut into bite-sized pieces
• 3 cloves garlic, minced
• 4 cups Yukon Gold potatoes, peeled and diced into small cubes
• 1 cup shredded cheddar cheese
• ¼ cup grated Parmesan cheese

Creamy Sauce

• ¼ cup butter
• ¼ cup all-purpose flour
• 2 cups chicken broth
• 1 cup heavy cream
• 1 teaspoon garlic powder
• Salt and pepper to taste

How to Make Chicken Broccoli Potato Casserole:

1. Preheat the oven to 375°F. Grease a 9×13-inch baking dish with cooking spray and set it aside.
2. 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.
3. In a large skillet, heat the olive oil over medium heat. Add the chopped onion, sautéing them until they become translucent and fragrant.
4. Season the chicken with salt and pepper to taste, Italian seasoning, and paprika.
5. 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).
6. Add the minced garlic and cook for 1 minute.
7. To make the 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.
8. 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.
9. 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.
10. Transfer the mixture into the prepared baking dish. Sprinkle shredded cheddar cheese and grated Parmesan cheese over the top.
11. 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.
12. Allow the casserole to cool for a few minutes before serving. Serve and enjoy!
