Ingredient Notes and Substitutions

Shredded hash browns – You can use fresh or frozen hash browns. See notes below for tips on how to thaw.
Cheese – we used shredded cheddar cheese for a classic flavor, but you can use Colby jack for a more melty texture.
Ham – Precooked ham is great in this dish, however, you can use any type of cooked ham that you like.
Sour cream – Use regular sour cream for a richer taste and texture. Substitute with Greek yogurt for a lighter option.
Milk – Evaporated milk was used as it gives a richer texture. But, you can use half and half instead.
Butter – melted butter is used to help bind the ingredients together. You can use olive oil instead. However, the flavor may be slightly different.
Seasoning – We used all-purpose seasoning and pepper.

How To Thaw Frozen Shredded Hash Browns

I prefer to let the frozen hash browns defrost on a baking sheet. It takes about 30-60 minutes total.

If you’re in a hurry, you can place the frozen hash browns on a baking sheet. Bake then bake them at 170º Fahrenheit for about 15 minutes to thaw them quickly.

Of course, you can always thaw frozen hash brown potatoes right in their bag overnight in the refrigerator. Put a plate or container underneath the package of shredded potatoes baking while defrosting in the fridge to keep them from making a mess.

🎯 TFN Pro Tip

Do not rinse hash browns (fresh or frozen)! The potatoes will soak up the water and it will make your casserole soggy.
