Ingredients You’ll Need

• 4 large russet potatoes (peeled and cut into cubes)
• 4 tablespoons unsalted butter
• ½ cup sour cream
• 1 cup shredded cheddar cheese (plus more for topping)
• ¼ cup milk (or more for desired consistency)
• 1 teaspoon garlic powder
• Salt and pepper to taste
• Fresh chives or green onions for garnish (optional)

Ingredient Notes and Variations

• Russet Potatoes: Russets are ideal because they have a starchy texture that yields fluffy mashed potatoes. You can substitute with Yukon Golds for a creamier texture.
• Cheese: Use sharp cheddar for a tangy flavor, but you can also mix in other cheeses like mozzarella or Parmesan for added richness.
• Sour Cream: Adds creaminess and tang. If you prefer a lighter option, swap sour cream for Greek yogurt.
• Butter and Milk: These two ingredients contribute to the creaminess. You can adjust the milk quantity to reach your desired potato consistency.

For those wanting to reduce carbs, our Sausage Cauliflower Casserole is another comforting alternative that’s just as satisfying.

Kitchen Equipment You’ll Need

• Large pot for boiling potatoes
• Potato masher or hand mixer
• Baking dish (9×13 inch works well)
• Wooden spoon or spatula
• Measuring cups and spoons
• Knife and cutting board
• Grater for cheese

Step-by-Step Preparation: How to Make Twice-Baked Mashed Potatoes

Step 1: Boil the Potatoes
In a large pot, bring water to a boil and add the cubed russet potatoes. Boil for 12–15 minutes until the potatoes are fork-tender.

Step 2: Mash the Potatoes
Drain the potatoes and return them to the pot. Add the butter, sour cream, garlic powder, salt, and pepper. Mash until smooth, adding milk gradually until you reach your desired consistency.

Step 3: Add Cheese
Stir in the shredded cheddar cheese until it melts into the potatoes, creating a creamy, cheesy mixture.

Step 4: Stuff the Potatoes
Transfer the mashed potatoes into a greased baking dish, smoothing the top with a spatula. Sprinkle additional cheese on top for a cheesy crust.

Step 5: Bake for the Second Time
Preheat your oven to 375°F (190°C). Bake the potatoes uncovered for 15–20 minutes, or until the top is golden and bubbly.

Step 6: Garnish and Serve
Remove from the oven and garnish with fresh chives or green onions for an extra burst of freshness. Serve immediately as a decadent side dish.

Pro Tips for the Best Twice-Baked Mashed Potatoes

• Don’t overcook your potatoes: Boil until just fork-tender to avoid mushy mashed potatoes.
• For extra fluffiness: Use a potato ricer or food mill instead of a masher for smoother results.
• Adjust the seasonings: Taste your mashed potatoes before baking and add more butter, salt, or garlic if needed.
• Get creative with cheese: Feel free to mix in other cheeses like Gruyère, Monterey Jack, or even a touch of blue cheese for extra flavor.

Common Mistakes to Avoid

• Not mashing thoroughly: Make sure you mash the potatoes well to avoid lumpy results.
• Under-seasoning: Potatoes can be bland on their own, so be sure to taste and season generously.
• Skipping the second bake: The second baking step is what gives these potatoes that irresistible golden top, so don’t skip it!

How to Store and Reheat

Reheating: Reheat in the oven at 350°F (175°C) for 10–15 minutes, or until warmed through. You can also reheat in the microwave, though the crispy topping won’t be as crunchy.

Freezing: You can freeze twice-baked mashed potatoes for up to 2 months. To reheat, let them thaw overnight in the fridge, then bake in the oven at 350°F until hot.

Make-Ahead Tips

• Prep in advance: Make the mashed potatoes a day ahead and assemble them in the baking dish. Cover and refrigerate until ready to bake.
• Double the recipe: Make a larger batch and freeze for future meals. They’re great to have on hand when you need an easy side dish.
