What is Twice Baked Potato Casserole? 

This baked potato recipe is one you have to plan in advance since it takes a total of two and a half hours to make.

It serves six people and is filling enough to be a main dish but also works well as a side dish or appetizer. 

Ingredients: 

• 2 pounds potatoes: Yukon potatoes are large and perfect for this dish.

• 3 tablespoon flour: All-purpose flour combines with the butter to make a roux.

Tips for success: 

Here are a few tips for success and variations you can try to make this the best twice baked potato casserole you've ever had.

• You can substitute cheddar with mozzarella, havarti, Gruyere, bleu, parmesan, or a combination of different cheeses. 
• Make these potatoes into a breakfast meal by adding a side of eggs.  
• You can make these potatoes healthier by leaving out the bacon and butter and cutting the cheese in half. 

What types of potatoes can I use in this casserole?  

You can use other types of potatoes besides Yukon. Try sweet potatoes, canned yams, mashed potatoes, hash browns, or sliced potatoes. Some of these potatoes will require you to combine the ingredients into a casserole dish rather than into individual potato skins.  

What kind of meat can I add to make this a main meal?  

Bacon is a delicious complement to potatoes, but you can substitute or add other types of meat as well. Some tasty options include ground beef, ground sausage, shredded chicken, or diced ham.  

Can I make this twice baked potato casserole in an instant pot?   

If you want to use the oven for another dish or don’t want to heat up a large appliance, you can use a pressure cooker to make these potatoes. It also takes much less time to cook this way.  

Use the pressure cooker to cook the potatoes until they’re soft. Remove the potatoes, and use the saute function to cook the bacon. Whisk in the butter, flour, and milk, and simmer until the sauce thickens. Mix the potatoes from the skins, sour cream, bacon, half the cheese, and half the scallions in with the sauce.

Top with the other half of the cheese and scallions, seal on the lid of the instant pot, cook for 30 minutes, carefully release the pressure, and remove the lid. Serve while hot.   

How to store twice baked potato casserole:

Store any leftover casserole in an airtight container in the refrigerator for up to five days. Reheat it in the microwave with 30-second increments until it’s hot all the way through. 

To freeze the entire casserole, wrap it in aluminum foil and plastic wrap. Label it with what it is, how to cook, and the date. Labeling will help you remember later. Remember that if you cook it from frozen, it will take longer to cook in the oven without thawing first. Keep the foil on until the last 30 minutes of cooking so the top can brown.
