The knife should slide easily into the biggest potato before you pull the tray from the oven. That’s the cue I trust with a batch this size; the smaller russets may be ready first, but the largest one tells you whether the centers are tender enough to mash.
This Pioneer Woman Twice Baked Potato Casserole takes the familiar twice-baked filling out of the skins and spreads it in a 9×13-inch dish. The potatoes bake whole first, then get mashed with butter and dairy until the mixture is creamy but still has a little texture. Crisp bacon and melted sharp cheddar make a savory top, while green onions go on after baking for a fresh finish. It’s a substantial side dish with soft potato underneath and a salty, cheesy layer on top.
Kitchen Note
Give the casserole its full 10-minute rest after it comes out of the oven. The center settles as it sits, and adding the green onions afterward keeps their fresh bite distinct from the rich, melted topping.

Why a Little Texture Keeps This Casserole from Eating Like Whipped Potatoes
With five pounds of russets, it’s tempting to mash until every last lump disappears. But this is a twice-baked potato casserole, not a silky potato purée. Leaving small chunks gives each serving a more substantial, potato-forward bite beneath the cheese and bacon.
Russets are starchy, and working them hard after they’re cooked can turn the mixture gluey. Mash just until the butter and dairy are combined, then stop while a few small pieces remain. The casserole will bake again, so there’s no need to chase a perfectly smooth texture in the bowl. A few lumps aren’t a mistake; they’re part of the contrast between the soft filling and the browned, melted topping.
What the Russets, Dairy, and Topping Each Bring to the Pan
- Russet potatoes — Their starchy, relatively dry flesh turns fluffy when baked and holds the butter and dairy without making the filling loose. Regular grocery-store russets work well. Yukon Golds can stand in at the same weight, but their flesh is denser and the finished casserole less fluffy; scrub the potatoes and pierce them before baking.
- Butter, sour cream, and whole milk — Butter adds richness, sour cream brings tang, and milk loosens the mash enough to spread. Standard supermarket versions are fine; there’s no need for specialty dairy. Plain Greek yogurt can replace the sour cream measure for measure, with a slightly tangier result, and 2% milk can replace whole milk with a little less richness.
- Seasoned salt and black pepper — Seasoned salt gives the potatoes more depth than plain salt alone, while pepper cuts through the creamy filling. A familiar grocery-store seasoned salt is all you need. White pepper can replace black pepper in the same amount if you’d rather avoid dark flecks; its flavor is milder.
- Bacon — Crisp bacon supplies the smoky, salty crunch that makes the top taste like a twice-baked potato. Regular sliced bacon is a good choice; an expensive specialty bacon isn’t necessary. Turkey bacon can replace it, though the topping will be leaner and less smoky, and the crisping time may vary by brand.
- Sharp cheddar and green onions — Sharp cheddar gives the topping a stronger, tangier finish than mild cheddar. Bagged shredded cheese is convenient and works; freshly shredded cheese tends to melt more smoothly. Monterey Jack can replace the cheddar for a milder topping, while sliced chives can replace the green onions for a more delicate onion note.
From Tender Baked Russets to a Bubbling Cheddar Top
Bake the Potatoes Until the Largest One Is Tender
Heat the oven to 400°F. Pierce each scrubbed potato several times with a fork and set them on a rimmed baking sheet; bake for 55–70 minutes, until a knife slides easily into the center of the largest potato. Let them cool for 10–15 minutes, until you can handle them comfortably. Cut each potato in half and scoop the flesh into a large bowl, leaving the skins behind.
Mash and Spread the Filling
Add the butter, sour cream, whole milk, seasoned salt, and black pepper to the potato flesh. Mash until the ingredients are combined, stopping with small chunks still visible rather than beating the filling smooth. Reduce the oven to 350°F and coat a 9×13-inch baking dish with nonstick cooking spray. Spread the potato mixture evenly in the dish so the topping has a level surface.
Cook the Bacon, Then Bake the Topping
Cook the bacon in a 12-inch skillet over medium heat for 8–12 minutes, turning as needed, until crisp. Drain it on paper towels and crumble it once it’s cool enough to handle. Sprinkle the cheddar and bacon over the potatoes, then bake for 20–25 minutes, until the casserole is hot throughout and the cheese has melted. Let it rest before finishing with the sliced green onions.
Three Easy Ways to Change the Topping or Make It Dairy-Free
Give the Topping a Pepper Jack Kick
Replace the sharp cheddar with shredded pepper Jack. It melts into the same kind of cheesy layer, with a little heat and a milder cheese flavor. Keep the bacon and green onions for the familiar smoky, fresh contrast.
Make a Dairy-Free Version
Use plant-based butter, plain dairy-free sour cream, unsweetened plain oat milk, and dairy-free shredded cheddar in place of the dairy ingredients. The filling will be less rich, and dairy-free cheese may melt less smoothly than cheddar, but the russets still make a hearty base. The bacon remains in this version.
Make It Vegetarian
Use plant-based bacon in place of pork bacon and cook it until crisp according to its package directions before crumbling it over the potatoes. It adds a savory, crunchy topping, though the smoky flavor can vary among brands.
Storage and Reheating
- Refrigerator: Refrigerate leftovers within 2 hours and keep them covered for 3–4 days. The potato filling firms as it chills.
- Freezer: Freeze portions in airtight containers for up to 1 month. Thaw overnight in the refrigerator; the potatoes may be a little grainier after freezing.
- Reheating: Reheat in a covered oven-safe dish at 350°F until the center reaches 165°F. Keeping it covered helps the potatoes stay moist; uncovering it for the whole reheating time can dry the top.
