Twice-baked potato casserole

Potatoes so nice we baked them twice for this yummy casserole dish. 



  • 1.15 kg (2 1/2 lbs) baking potatoes, such as Russets
  • 4 garlic cloves, peeled
  • Kosher salt
  • 1/2 cup (125 ml) buttermilk or cream
  • 1/2 cup (125 ml) sour cream
  • 1/2 cup (125 ml) cream cheese
  • 3 tablespoons butter
  • 8 slices bacon, cooked crisp, rendering reserved
  • 5 green onions
  • 1 1/2 cups (170 g) grated cheddar cheese
  • 2 tablespoons olive oil or reserved bacon fat
  • Freshly ground black pepper


  1. Heat your oven to 400ºF and lightly grease a nine-inch square casserole dish with non-stick cooking spray. Set aside.
  2. Scrub and dry the potatoes well. Using a vegetable peeler or a paring knife, peel the potatoes, setting peels aside for later, and cut the potatoes into quarters. Place into a large saucepan and cover with cold tap water. Add in the garlic, season well with salt, and bring to a boil over medium-high heat. Cook the potatoes until tender, about 15 to 20 minutes, then drain and return the potatoes and garlic to the pot.
  3. Add the buttermilk or cream, sour cream, cream cheese, and butter to the potatoes and place a lid on the pan to allow the butter to melt and the cream cheese to soften. Using a hand mixer, beat the potatoes just until smooth.
  4. Finely chop six slices of bacon and thinly slice four green onions. Add the potatoes along with half a cup of cheddar cheese. Stir well to combine and season to taste with more salt if needed. Transfer the potatoes to the prepared casserole dish and bake the for 10 minutes.
  5. Meanwhile, toss the reserved potato peels onto a sheet pan and drizzle with the olive oil or reserved bacon fat. Season well with salt and pepper and, using your hands, toss very well to combine and evenly coat. Spread the peels into a single layer.
  6. Remove the potatoes from the oven, top with the remaining cheddar cheese, and return to the oven along with the pan of potato peels for 15 to 20 minutes or until the potatoes are golden around the edges and the peels are crisp.
  7. Roughly chop the remaining bacon and slice the remaining green onion. Allow the potatoes to cool slightly before topping them with the bacon, green onion, and crispy potato peels. Enjoy!
