Ingredients and Substitutions For Your Twice Baked Potato Casserole Recipe

Ingredients used to make twice-baked potatoes casserole
Twice Baked Potatoes Casserole Ingredients
  • Potatoes. Wash the potatoes but do not peel them. You’ll need approximately 8-9 golden potatoes cooked and diced. Boil until tender or throw them in the pressure cooker for 27 minutes.
  • Butter. Salted or unsalted.
  • Milk. Any kind of milk will do. Do not substitute with heavy cream. See notes.
  • Salt and Ground Pepper.
  • Garlic Powder. The powder form will ensure garlic flavor in every bite.
  • Minced Garlic. The minced form will amp up the garlic flavor and make it shine.
  • Ground Celery Seeds. This familiar flavor will add another layer of flavor.
  • Onion. We used a red onion but your favorite onion will work.
  • Bacon. You can use bacon bits or cook 3-5 slices in a microwave between paper towels or in a skillet.
  • Shredded Colby Jack. I love using Colby Jack in a block that I shred at home. It melts very good and has a milder taste than Cheddar. You can substitute with Cheddar — sharp or mild or any of your favorite cheese blends.
  • Sour Cream. Full fat or reduced fat.

How To Reheat & Store Twice Baked Potato Casserole Recipe

Best Way To Store Twice Baked Mashed Potatoes Leftover

Store your leftover casserole in the refrigerator for 3 days using an airtight container.

Can I Freeze Loaded Baked Potato Casserole?

Yes. Freeze the casserole whole or in individual servings using an airtight container for up to 3 months.

How To Reheat Twice Baked Mashed Potatoes

This dish can be reheated from the frozen state. Preheat the oven. Cover the casserole with foil and bake for 20 to 25 minutes. Can also be microwaved for about 4 to 5 minutes, stirring. Reheating twice baked potatoes casserole might get a little watery. You can drain the liquid off or stir it in.

Tips for the Perfect Twice Baked Potato Casserole Recipe

Don’t over-mash the potatoes or your casserole will be gummy and you will lose the texture.

This recipe can be doubled. Just use a larger pan. I use my lasagna pan. You can also make half the amount. Again just use an appropriately-sized pan.

You may need to adjust the milk in the mixture if you are doing more potatoes. Just make sure when you are mixing the milk and the butter you don’t want it too soupy. Your mixture is soft but still has a potato structure.

I did not peel the potatoes. The peeling of Golden potatoes is very thin. They add an extra texture that we enjoy.

Time may vary when boiling the potatoes as every potato is different. They are cooked when you can insert a fork easily into the potato.

When serving the potato casserole you can sprinkle fresh green onions on top if desired.

Popular Variations & Additions

  • We used Golden potatoes, but you can use Russet or red potatoes as well.
  • You can substitute the milk with chicken broth if desired. I found out that if I substitute with cream the mixture is not as nice and fluffy.
  • Have fun changing the flavors, add more or less of your favorite seasoning, and spice it up a bit with a few drops of hot sauce.
  • Change the cheese to Cheddar, Pepper Jack, or Smoked Gouda.

What to Serve to serve with Your Loaded Baked Potato Casserole

Servings: 9

Ingredients
 
 

  • 6 cups Potatoes (approximately 8-9 golden potatoes), cooked and diced. We used Golden potatoes washed, do not peel. Boil until tender.
  • 4 tbsp butter I used salted butter but you could have used unsalted
  • 1/3 cup milk any variety
  • 1 tsp salt
  • 1 tsp garlic powder
  • 1 tsp minced garlic
  • 1 tsp ground celery seeds
  • ½ tsp ground pepper
  • ½ cup chopped onion we used red onion but you can use white or sweet onion as well
  • ½ cup chopped bacon more for topping (you can use bacon bits)
  • 2 cups shredded Colby Jack divided I love using Colby Jack in a block that I shred at home. It melts very good and has a milder taste than Cheddar. You can substitute with Cheddar sharp or mild or any of your favorite cheese blend.

Instructions
 

  • If your potatoes are not cooked, washed and diced them. Place in a saucepan with water and a hint of salt.
    Boil the potatoes until they are tender and can easily be pierced with a fork in the middle.
    The larger their cubed, the longer they will take to cook. For 1-inch cubes, I boil them for 15 minutes.
  • Preheat your oven to 375 °F. Butter a 9×13 baking dish and set aside.
  • Place the cooked potatoes into a large mixing bowl.
  • Add the butter and the milk. With a hand mixer or potato masher, mash the potatoes to a puree. I used a hand mixer for this step.
  • Add the salt, garlic powder, minced garlic, celery seeds, and ground pepper. Mix until the seasonings are well blended with the potatoes.
  • Add the chopped onions and bacon bits and mix well.
  • Add 1 cup of the shredded Colby Jack and the sour cream. Mix until all ingredients are well combined together.
  • Spread the potato mixture in the prepared 9 x 13 bake dish. Spread evenly.
  • Sprinkle the remaining 1 cup of cheese and sprinkle additional bacon bits on top if desired.
  • Baked in the preheated oven for 25 minutes or until the cheese is nice and melted.
