How to make Twice Baked Potato Casserole
Start by baking your potatoes until fork tender. Then, plunge the baked potatoes into ice-cold water. Once the potatoes are cooled, drain well. Using your fingers, gently and easily peel the potatoes. Carefully cut the hot potatoes into large cubes.
Then, in a large mixing bowl, combine the mashed potatoes with all the goodies and spoon into a casserole dish. Top with the remaining cheese, bacon, and green onions. Cover the dish with foil and bake for about 30 minutes. Then remove the foil and bake until the cheese is melted and the casserole is hot.
Make it in Advance
Prepare this casserole up to 2 days in advance. Assemble the casserole, but do not bake. Cover the dish with plastic wrap and put it in the refrigerator. Remove it from the fridge 45 minutes before baking to bring it to room temperature. Cover with foil and bake at 375 degrees for 30 minutes. Remove the foil and bake for another 10 minutes or until the cheese is melted and the casserole is heated.
Preparation Tips
- Use starchy potatoes like Russet or Yukon Gold potatoes for this recipe.
- Plan so there is plenty of time to bake the potatoes.
- Once baked, plunge the potatoes into ice water, making them easy to peel with your fingers.
- Any good melting cheese, including cheddar, Monterey Jack, Pepper Jack, Colby Jack, Gouda, or Provolone, works well with this recipe.
- Use good quality smoked bacon and cook it crispy. The easiest and quickest way is to cook the bacon in the oven.
Storage and Reheat
Leftovers can be stored in an airtight container in the fridge for up to 3 days. They can be reheated in the microwave at reduced power or in the oven at 350 degrees covered for about 30 minutes or until warm.
Recipe FAQS
Prepare per the instructions up to the point of spooning the mixture into a casserole dish. Instead, assemble it in a crock pot, including the toppings. Heat on low for about 2 hours or on high for slightly over an hour. The cheese should be melted, and the casserole heated through. Then, turn the crock pot to warm for you and your guests to enjoy whenever you are ready.
To freeze, cool completely. Then, wrap in two layers of plastic wrap followed by a layer of aluminum foil. Freeze for up to 2 months. Thaw in the fridge overnight. Take the casserole from the fridge 45 minutes before reheating to bring the casserole to room temperature. Reheat leftovers in the microwave at reduced power or in the oven, covered at 350 degrees, for about 30 minutes or until warm.
