What You’ll Need

Frozen hash browns – Grab a 30-ounce bag of frozen hash browns, or you can use diced potatoes or frozen breakfast potatoes instead.
Onion – I mix it in raw, but if you would like, you can saute the onion in a bit of butter or olive oil first.
Cream of chicken soup – Cream of mushroom soup is also okay to use.
Butter
Sour cream – You could use plain yogurt here if you’d like.
Mayonnaise
Seasonings – Salt, pepper, and garlic powder.
Shredded cheddar cheese – Feel free to use a different cheese. Pepper Jack or Gruyere would both work beautifully.

No lumps. Break up any clumps of hash browns with your fingers before mixing them with the remaining ingredients.
Let it rest. After taking the hash brown casserole out of the oven, let it rest for 10 minutes so the casserole has time to set.
Add a breakfast protein. Feel free to add cooked and crumbed sausage or bacon, crispy ham, or even shredded rotisserie chicken into the mixture before baking.
Mix in some veggies. Stir roasted bell peppers and sauteed mushrooms into the hash browns before popping them in the oven.
Play with flavors. You could kick up the flavor by swapping out a bit of the cream chicken soup for some ranch dressing or Thousand Islands dressing. Use herbs and spices if you’d like as well. I like to mix some smoked paprika and ground mustard.

To reheat. Allow the hash browns to thaw in the fridge (if frozen) before transferring them to a baking dish (if applicable) and baking, covered at 350°F for 20 minutes or until heated through. Alternatively, microwave one or two slices at a time in 30-second intervals until warm.
