Serving Suggestions

This Chicken Hash Brown Casserole is a meal all by itself or you can stretch it by adding a few simple side dishes. Steamed green beans, Brussels sprouts, or glazed carrots are delicious and colorful options.

Serve a crisp fresh green salad for some extra crunch! A side of mashed potatoes, or a slice of cornbread taste great too!

How long does it last?

If you have any leftovers, be sure to cool completely. Store in an airtight container and keep in the fridge for 3-4 days. Reheat in a preheated oven or microwave until heated through.

Can I freeze it?

Freezing your Chicken Hash Brown Casserole is a snap and makes for easy meal prep for those busy nights.

Put the casserole together, leave off the topping, and bake like you normally would. Cool to room temperature. Cover in plastic wrap and a layer of aluminum foil, date, and store in the freezer for up to 2 months.

When you’re ready to serve, thaw overnight in the fridge. Add the topping and bake in the oven until heated through and the topping is crunchy.

If you are prepping ahead of time, leave the topping off and put it on just before baking so it doesn’t get soggy.

Dinner Casseroles

Casseroles are a perfect no-fuss dinner if you want to whip up something easy that your family will enjoy. They use simple pantry ingredients like noodles, vegetables, and condensed soups, and are stress free for you.

Best of all, casseroles let you use up leftovers and stretch higher cost items like meat even further. Much like this Hashrown taco casserole.

So on those busy nights when you want to gather everyone around the table for an easy, feel-good meal, a delicious, family-friendly casserole is the way to go. This 5 ingredient chicken broccoli casserole is super easy, and just 5 ingredients like the name says.

Tips for the Best Casserole

Butter or use nonstick cooking spray to prepare the casserole dish.
If you don’t have garlic salt, combine 1 part garlic powder with 3 parts salt.
Be sure to thaw and drain the frozen hash browns so the dish isn’t soggy.
Use leftover chicken breasts or a rotisserie chicken for easier prep on busy nights.
Substitute the cornflakes for crushed Ritz crackers.
Leave out the spices and use a packet of ranch dressing mix instead.
If the top browns too quickly, cover lightly with aluminum foil for the rest of the baking time.
