Re-Heating This Cheesy Onion Hash Brown Bake

I made a whole 9 X 13 pan of these potatoes last week and the four of us did our best, but were not able to eat the whole thing! Ha. We had a few pieces leftover and a day later, this potato side dish because our breakfast. I melted 1 tablespoon of butter in my cast iron pan. Added the hash browns potato side down. Cooked about 10 minutes covered on medium-high heat.

Just look at how cheesy and crispy those potato hash browns ore on the second day!

Re-heating the potatoes this way does three things: covering the pan makes sure to get the cheese all melty again. Additionally, the addition of the butter to the pan not only helps the potatoes not stick but adds more buttery-rich flavor. Lastly, not moving the hash browns and letting them heat in the pan makes the bottom of the potatoes all crispy again. Yum!  They are now all gone.

Freezer Potato Meal

This can be made as a freezer meal. Great to give to help a friend or neighbor out in their time of need.  That is what our neighborhood does. We all take care of each other by bringing over meals when someone is going through a rough patch.

To make this as a freezer meal side dish, do not thaw the potatoes. Empty the frozen hash browns into a bowl, add the olive oil melted butter, salt, and pepper and mix. Put this in a 9 X 13 container that has been sprayed with oil.  Then layer on the onions and cheeses. Cover securely and freeze for up to 3 months.

To make this from the frozen state, lower the oven temperature to 350 degrees Fahrenheit and bake for 45 minutes. Then raise the temperature in the oven to the 425 degrees Fahrenheit and continue baking 20 minutes covered. Then remove the cover and bake another 15 minutes until the cheese is melty and bubbly and the potatoes are cooked through and starting to crisp on the bottom and sides. (If you take the time to thaw this before baking, just follow the baking directions in the recipe).

When giving this freezer meal as a gift, I will use a disposable foil pan and cover with foil. Make sure to crimp the edges of the foil well so it stays in place. Use a marker to label what is inside and the cooking time.

Potato Casserole Recipe Options

This potato casserole is just like the potatoes we order in a restaurant not far from our house. We love them! When we make them at home, it feel like more of a comfort food than a fancy restaurant menu item. Either way, very easy. Here are a few ideas for you to think about as you make this recipe for your favorite people in your life.

Serve with a bit of diced green onion sprinkled on top after baking.

Add some heat. Sprinkle Cajun seasoning over the potatoes just before adding the onions.

If you like just a little heat. Sprinkle Paprika seasoning over the potatoes just before adding the onions.

Melt a bit more butter and drizzle it over each piece that you serve your guests. I know in our butter-loving family, this would take this recipe over the moon.

I use regular salt in this recipe; however, that could be swapped out for something like a seasoned salt. I happen to have just a homemade seasoned salt recipe you should try.

Here are a few other delicious ways we enjoy potatoes at our house.
