- Bake the potatoes: Wash the potatoes and prick them all over with a fork. Bake them at 400°F for 45-60 minutes. Once they are fork-tender, remove the potatoes from the oven and let them cool. Reduce the oven temperature to 350°F.
- Mash and season the potatoes: Cut the potatoes in half lengthwise and scoop out the flesh into a large bowl. Add the butter, half & half, and mash until creamy. Add cheese, season the mixture with salt and stir.
- Bake the casserole: Transfer the mashed potatoes to an oiled 9×13 inch baking dish. Add the bacon and remaining cheese on top, then cover the dish with foil and bake at 350°F for 20 minutes. Remove the foil and bake for an additional five minutes, or until the top is nice and golden. Garnish with green onions and enjoy!

Tips From the Kitchen
There’s something about potatoes… is it their carb-y comfort? Or maybe their versatility? Regardless of the reason, we’ve compiled a few tips to make this a five-star-worthy casserole.
- Use russet potatoes. Russets have the lowest moisture and highest starch content of all potato varieties, which makes them the best choice for light and fluffy mashed potatoes. If you can’t get your hands on russet potatoes, Yukon gold potatoes are the next best option.
- Bake the potatoes until they are fork-tender. Since the assembled casserole only gets a 20 minute stint in the oven, it’s important for the potatoes to be fully cooked beforehand. This also makes them easier to mash!
- Mash the potatoes to your liking. Some prefer a perfectly smooth mash, and others like it chunky. A good potato masher comes in handy at a time like this!
- Don’t skimp on the dairy. There’s a reason this recipe isn’t low-fat — butter, half & half, sour cream, and cheese add essential richness and flavor to the casserole that isn’t worth skipping out on.
- Make it your own. Not a fan of sharp cheddar cheese? Try pepperjack, mozzarella, or Swiss instead. If you love extra-creamy mashed potatoes, consider adding cream cheese! For a single-serving indulgence, divide the casserole into mini cocottes like these.
Make Ahead
Whether it’s the holiday season or everyday life, sometimes time can get the best of us. Stay ahead of the rush by preparing this twice baked potato casserole in advance! Follow the recipe up to the point of baking, then cover the assembled casserole and refrigerate it for up to two days. When you’re ready to serve, pop the casserole in the oven and bake as instructed.
Ways To Serve
Twice baked potato casserole is a delicious and unforgettable dinner side dish. Serve it fresh out of the oven with chopped green onions for garnish and a side of sour cream. For the main protein, impress your dinner guests with either a pork roast, sirloin tip roast, grilled lamb chops, or braised beef short ribs. For a lighter pairing, serve with caesar salad or creamy cucumber salad.

Storage & Reheating
This recipe makes a generous amount of servings, so you’re likely to have tasty leftovers. Follow these guidelines to continue enjoying your casserole for days or months to come!
- Refrigerator: To store for up to three days, allow the baked casserole to cool completely. Then, cover the casserole dish with a lid or aluminum foil and refrigerate.
- Freezer: To store for up to three months, double-wrap the casserole dish or transfer the casserole to an airtight container and freeze. Thaw the frozen casserole in the fridge overnight before reheating.
- Reheating: For the best results, reheat the casserole in the oven at 400°F for about 15-20 minutes. If you’re short on time, a large skillet or the microwave also works.
