I love, love a twice baked potato. I do NOT love, love making them. Getting that wonderful mixture of potato and cheese and bacon back into the potato skins without destroying said skin is too much for me. The skins rip and tear and then I lose a potato boat. It’s never been my specialty.
Enter: The Twice Baked Potato Casserole. We’re gonna take all of the wonderful parts of a twice baked potato and put it in a baking dish and finish it in the oven. Sans filling the potato skins. It’s so lovely and so easy, that you’ll make it all the time when you need a side dish that everyone loves.
This recipe is a perfect side dish for steaks, roasted chicken, pork, and your favorite seafood. My kids have even been known to request a bowl for dinner. I’d be lying if I said I wasn’t right there with them enjoying what is arguably our favorite side dish ever. It’s great for everyday, perfect for the upcoming holiday season, and will be a hit with whomever you serve it.

how to make twice baked potato casserole
baking the potatoes, garlic, and green onion
To begin this Twice Baked Potato Casserole, we need to address our potatoes, green onions, and garlic. The potatoes bake in a 400° oven for about an hour or until they’re tender. Depending on the size of the potatoes, this can take less than an hour or more than an hour.
Into the same oven, we will roast the garlic and green onion tops. This step is completely optional, but adds a ton of flavor.
Trim the top 1/4 inch off the top of the garlic bulb. Place the garlic cut-side up onto a piece of foil along with the white onion tops, drizzle with avocado oil, and sprinkle with kosher salt. Wrap the garlic and green onion tops in the foil.
Place the packet into a small baking dish and add that to the oven along with the potatoes. The garlic and onions will be done anywhere from 45 minutes – 1 hour. If the potatoes need more time in the oven, simply remove the garlic and onions and let them cool while the potatoes finish cooking.
the bacon
While the potatoes, garlic, and green onions are doing their thing in the oven, it’s also a great time to cook the bacon. I throw mine on a sheet pan and stick in the oven with everything else. Make it easy! Cook the bacon according to your preference. I like mine a bit crispy for the texture and for the crunch on top. Truly, is there much better than a crunchy bacon topping? I think not.
Once the bacon is cooked to your liking, finely chop it. Reserve some for topping the casserole for later on.
making the twice baked potato casserole
Once the potatoes have become tender in the oven, remove them and let them cool to the point that you are able to comfortably handle them. Cut the potatoes in half and scoop out the insides into a large mixing bowl. Mash or breakup the potato pieces to your liking. You can make the pieces as large or as small as you would like.
To make this Twice Baked Potato Casserole the best it can be, we need to add some really good things. In a separate mixing bowl, combine the all-purpose seasoning, melted butter, heavy cream, sour cream, half of the grated cheeses, and most of the bacon. Mash the roasted garlic cloves and mince up the roasted green onion tops and also add those to the mixing bowl. Mix everything to combine.
Pour the butter mixture over the potato pieces, mixing to throughly combine. Add the casserole mixture to a lightly greased 9×13 baking dish. Top with remaining cheese and bacon and bake the Twice Baked Potato Casserole in a preheated 400° oven for 20-25 minutes. Garnish with the tops of the green onions.
Let it cool slightly and dig in!
recipe frequently asked questions
In my opinion, the russet potato is the one to use. It has the perfect amount of starch and will not become glue-like when mashed.
Yes! Prepare the recipe to the point of the second baking. Refrigerate, covered, for up to 48 hours. If freezing, cover well and freeze for up to 3 months.
In order to cook a frozen casserole, let it thaw out in the fridge overnight. Let is sit at room temperature for about 30 minutes on the day of cooking. Bake per the instructions. You may need to add 15-20 minutes of cooking time to get to that ooey-gooey bubbly stage.
