Ingredients and Substitutions For Your Twice Baked Potato Casserole Recipe
- 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.

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.
