  • Milk
  • Flour

How to make rotisserie chicken and potato casserole

First, preheat the oven to 350°F. Cook the diced potatoes in simmering water until fork-tender. Or about 15 minutes.

Drain and set aside.

Cubed potatoes that have been simmered until fork-tender.

In a large skillet over medium heated melt the butter.

When the butter is gently sizzling, add the mushrooms, onions, and bell peppers.

Cook this mixture for a few minutes until the veggies are softened, approximately 8-10 minutes.

Sprinkle the flour over the vegetables in the skillet.

Cook for 1 minute, stirring often.

Quickly remove the skillet from the heat and gradually whisk in the milk.

When the milk has incorporated into the flour a bit, return the skillet to the heat.

Cook the sauce for 2-3 minutes, stirring, until nicely thickened; season to taste with salt and pepper.

Into a greased 11×8 baking dish, add the shredded chicken and potatoes.

Pour the sauce and mushroom mixture over the top, then sprinkle with cheese.

Bake the casserole on the center oven rack for 30-35 minutes or until hot and bubbly throughout and 160 degrees F. at the center.

Let the casserole rest for 5 minutes before serving.

Does this casserole freeze well?

Not really, sadly.

Because this casserole contains potatoes, they can turn dark when the casserole is freezes.

However, this casserole is a great make-ahead casserole.

You can assemble it and then bake at a later time when you’re ready to cook dinner.

Does it matter which kind of potatoes I use in this casserole?

Not really. I typically always have russet potatoes on hand, so that’s what I almost always use. However, Yukon Gold potatoes make the texture of this casserole especially creamy, I’ve discovered.

Can I use other types of cooked meat in this casserole?

You sure can and I do it all the time. We really like shredded and cooked pulled pork in this casserole.

I’ve even used leftover cooked roast beef, too.

If I don’t want to purchase a rotisserie chicken for this recipe, can I just use shredded cooked chicken breasts that I’ve made at home?

Yep. It works great and sometimes I even use the dark meat from chicken thighs.

I love how economical boneless, skinless chicken thighs are, so I try to keep them on hand in my freezer at all times for casserole recipes like this one.

Can I make this a gluten-free casserole?

To make this a gluten-free dish, simply substitute a gluten-free flour in place of the all-purpose flour.

It works just fine.

Would this be a good recipe for using leftover turkey after Thanksgiving?

Absolutely!! Great idea.
