Why This Recipe Stands Out

This Creamy Baked Mashed Potato takes this classic side dish to a whole new level. Here’s why this recipe is a must-try:

  • Make-Ahead: I don’t have to fret and stress about having guests over with these mashed potatoes, because it’s make-ahead friendly. It can be prepped the night before and baked the next day!
  • Perfectly Creamy: We add softened cream cheese to these mashed potatoes for the most delicious creamy, luscious texture. It reminds us of our Cheesy Creamy Baked Ziti.
  • Easy to Customize: The recipe uses classic flavors, but it’s easy to customize it with your favorite cheese, herbs, and toppings.
  • The Ultimate Comfort Food: Creamy mashed potatoes are the ultimate comfort food, just like our Biscuits and Gravy Casserole.
  • Great for Gatherings: This recipe makes a large batch, so it’s perfect for family gatherings and holiday dinners.

Key Recipe Ingredients

Overhead shot of ingredients to make creamy baked mashed potatoes.
  • Russet Potatoes – The star of our dish, these starchy potatoes, when peeled and cubbed, provide a fluffy and creamy texture that’s perfect for mashed potatoes.
  • Cream Cheese – Adding cream cheese to our mashed potatoes not only makes them extra creamy, but also adds a subtle tangy flavor that sets this dish apart.
  • Garlic – We use minced garlic for a robust, aromatic flavor that takes these mashed potatoes to the next level.
  • Sharp Cheddar Cheese – This cheese, when shredded, adds a bold, cheesy flavor and a beautiful golden-brown crust on top of the mashed potatoes.

Substitutions And Variations

Here are some of our favorite variations and substitution ideas:

  • Cheese: Feel free to experiment with different types of cheese. Gouda, gruyere, or some parmesan would all work beautifully.
  • Garlic and Onions: If you love the flavor of caramelized onions, try adding them as a topping. We also recommend trying this Caramelized Onion Dip Recipe.
  • Herbs and Spices: This recipe is quite versatile when it comes to spices. You can add your favorites like paprika, rosemary, or thyme to the potato mixture before baking.

For Mashed Potatoes

  • 5 lbs russet potatoes, peeled/cubed

  • 4 cloves garlic, minced
  • 1 TB dried minced onion
  • 1 large egg, lightly beaten
  • kosher salt, to taste
  • black pepper, to taste

For Toppings

  • 5 slices thick-cut bacon, cooked and crumbled
  • 1 cup sharp cheddar cheese, shredded
  • 2 stalks green onions, thinly sliced

Instructions

  • Bring a large heavy pot of salted water to boil. Add potatoes and cook 15 minutes or just until tender but not mushy. Drain well and set aside.
  • In a large bowl, use a potato masher to mash potatoes with melted butter and milk.
  • Beat in softened cream cheese, garlic, onion, and egg. Beat until combined. Season with kosher salt and freshly ground black pepper to taste.
  • Transfer potatoes to a baking dish. At this point, you can bake it now or cover and chill to bake tomorrow.
  • Heat oven to 350F with rack on lower middle position. Bake uncovered for 60 minutes or until puffy and golden on top.

Notes

  • You can switch up the toppings as you’d like, or leave your mashed potatoes ungarnished. 
  • Make it vegetarian by omitting the bacon. 
  • For delicious serving ideas and variations, see original article. 
  • Soften your cream cheese well before mixing it with the potatoes. I like to gently microwave it in 20-second increments. It will blend in more easily and leave your mashed potatoes extra creamy.
  • This recipe is part of our Potato Recipes Collection.
  • Serve these creamy baked mashed potatoes alongside a classic Slow Cooker Pot Roast with Gravy or Juicy Perfectly Cooked Steak for a comforting and satisfying meal.
