Why you'll love this recipe
One of my favorite things that make this the perfect dish is that you can completely make this casserole ahead of time.
Refrigerate up to 3 days before serving, then bake as usual. Heads up - you'll need to add a bit to the cooking time if it's been chilled.
And then - go time!
It's a favorite side dish for holiday gatherings, family dinners, church potlucks and game day food! Serve this casserole and you'll feel the love in every bite! The leftovers even taste amazing.

Ingredients
- potatoes - personally, I think the best potatoes for this recipe are gold potatoes. They don't need to be peeled, they're creamy and they mix well with the other ingredients.
- onion powder
- salt
- sour cream - a must to add creaminess without watering down the potatoes.
- cream cheese - you can use regular or low fat cream cheese. Both add a little tang.
- shredded cheddar cheese - shred your own if you can find the extra three minutes. It makes these potatoes extra cheesy and creamy
- bacon - you can use store-bought bacon bits or make ahead bacon in the oven.
- green onions - for color and a subtle, onion flavor
Recipe variations
- Use fresh chives instead of green onions
- Cook bacon ahead of time in the oven!
- Add some cooked roasted garlic for an extra layer of flavor.
How to Make this Twice Baked Mashed Potatoes
I like to use Yukon gold potatoes in this potato side dish because you don't have to peel the potato skins. But if you prefer, you can use russet potatoes or another type of potato.
STEP 1: Bake the potatoes. To bake potatoes in the oven, heat your oven to 425 degrees F. Prick potatoes several times with a fork to allow steam to escape.
Place potatoes on the top rack of the oven and bake for 50-60 minutes until the potatoes are fork tender and can easily be pierced with a sharp knife.
Alternatively, you can also make your baked potatoes in the Instant Pot.
Step 2: Mix potato mixture. Cool potatoes slightly until they've cooled enough to handle. Cut cooked potatoes into quarters and add to a large mixing bowl.
Using a potato masher, mash potatoes and add the onion powder, salt, sour cream, cream cheese. Resist the urge to over mix them or the potatoes will become gummy. A chunk or two (or three) is perfectly okay.
Actually, delightful!
Step 3: Add the mixins. Once incorporated, add your shredded cheddar cheese, cooked bacon and green onions. Tip: you can cook bacon ahead of time in the oven!
Reserve a bit of bacon and green onions for sprinkling over the top of the potatoes. This lets everyone know what to expect when they take their first delicious bite.
Transfer the creamy mashed potato mixture to a casserole dish. They're headed into the oven for their second time because, you know...the whole twice baked deal.
Step 4: Bake the potato casserole. Cover with foil and bake until heated through. Remove the foil to slightly brown the top and edges towards the end of the baking time.
Yum!!!!
