What kind of potatoes should I use for loaded twice baked potato casserole?

This casserole recipe is super simple, especially if you already have leftover mashed potatoes to work with. If you don’t, you can either bake or boil them up.

To start with baked potatoes, you can wrap a few potatoes in foil and bake them in the oven at 400 degrees F.

However, I usually just peel the potatoes, cut them into cubes, and boil them until the pierce easily with a knife. Then I drain the potatoes and add them back to the boiling pot.

Next, I add the room temperature cream cheese and sour cream and begin mashing the potatoes and the cream cheese with a potato masher. Add the warm milk and butter and continue mashing, being careful not to over-mix.

Add 4 cups of the cheese, 10 slices of crumbled bacon, and 2 green onions, reserving the remainder of the ingredients for the topping.

Pour the potato mixture into a 9 x 12 baking dish and top with the remaining one cup of cheese, reserving the bacon and green onion for the final topping.

Bake the casserole in a 375 degree F. preheated oven until cheese is melted and the casserole is warmed through, about 30 minutes.

That’s it! How simple is that?

There are a few common questions that I am often asked about potatoes, so I thought I’d answer them below.

Why Are My Potatoes Gummy and Gluey?

There are several reasons for gummy potatoes. When I was first married, it was hit or miss as far as my having the perfect mashed potatoes or gummy ones. It was maddening to me.

However, I did a little research and began putting into practice the things I learned.

I came up with this list of 3 things that cause gummy potatoes.

1. Overworking the Potatoes

The more you work the potatoes, the more starch gets released. Too much starch causes gummy potatoes.

2. Adding Cold Ingredients to the Hot Potatoes

Adding cold ingredients to hot potatoes prevents the potatoes from absorbing the liquid and fat. The more liquid the potatoes absorb, the creamier the mashed potatoes.

3. Adding Too Much Fat and Liquid to the Potatoes

You can avoid making this mistake by:

  • adding the fat and milk in increments, barely mashing the potatoes to incorporate
  • adding only enough to make a mashed potato consistency

Keep in mind that this isn’t an exact science. The potatoes may be holding more moisture than a previous time of making mashed potatoes; thus they won’t hold as much. You really have to eyeball the amount of liquid and fat to some degree.

What Pairs Well with This Twice Baked Potato Casserole?

Just about everything pairs well with a good potato casserole. Some of my favorites are:

Can You Freeze This Casserole?

Yes! You can freeze it before baking and after; Just make sure they are cool before putting them in the freezer. I like to use plastic wrap and then 2 layers of tin foil.

If I know I am going to freeze the casserole, I will not top it with he cheese until after I thaw it for 24 hours in the refrigerator. Once thawed, top it with cheese and bake as instructed.

If you bake it, then wait for it to cool and wrap in plastic wrap and tin foil and freeze for up to 3 months.

You really cannot go wrong with this delicious comfort food. I know it will be a favorite in your house!
