When it comes to holiday meals, nothing beats creamy, buttery mashed potatoes but who wants to be stuck mashing at the last minute? These Make-Ahead Mashed Potatoes are the perfect solution. Ultra-creamy, packed with flavor, and topped with cheddar and bacon (optional, but amazing!), they can be prepared the day before and baked when you’re ready to serve. Stress-free, cozy, and totally crowd-pleasing!

This isn’t your average mash. These potatoes are:

  • Rich and creamy thanks to cream cheese, sour cream, and butter
  • Flavor-packed with garlic, onion powder, and cheddar cheese
  • Make-ahead friendly, saving time on busy holidays
  • Freezer-friendly, so you can prep well in advance
  • A side dish that pairs perfectly with turkey, ham, or roast beef
  • 3 lbs Yukon Gold potatoes, peeled and cubed
  • 8 oz cream cheese, softened
  • ½ cup sour cream
  • ½ cup butter, cubed
  • ¼ cup milk
  • 1 tsp onion powder
  • 1 tsp garlic powder
  • 1 tsp salt (or to taste)
  • ½ tsp pepper (or to taste)
  • 1 cup shredded cheddar cheese (optional)
  • 6 slices bacon, cooked and chopped (optional)
  1. Cook the potatoes → Boil until tender (about 15 minutes), then drain.
  2. Mash & mix → Mash potatoes, then stir in cream cheese, sour cream, butter, milk, and seasonings until creamy.
  3. Assemble → Spread into a greased 9×13-inch baking dish. Sprinkle with cheese and bacon (if using).
  4. Refrigerate or bake → Cover and refrigerate up to 24 hours. When ready, bake uncovered at 350°F for 40–50 minutes until hot and bubbly.
  • Use Yukon Golds: they’re creamy and buttery, perfect for mashing.
  • Don’t overmix: it can make potatoes gluey mash gently for a fluffy texture.
  • Cheese & bacon optional: leave them out if serving with gravy, or keep them in for a loaded casserole vibe.
  • Make-ahead magic: prep a day before and save oven time on busy holiday mornings.

Add a breadcrumb topping for extra crunch.
Stir in roasted garlic for deeper flavor.
Swap cheddar for parmesan or gruyère.
Make it vegetarian by skipping the bacon.
Freeze leftovers in portions for easy weeknight sides.

These potatoes are the ultimate holiday companion. Pair them with:

  • Roast turkey or chicken
  • Glazed ham
  • Meatloaf or beef roast
