Twice Baked Potato Casserole Recipe: The Perfect Side Dish For Any Meal

Twice Baked Potato Casserole is the kind of comfort food that makes you feel like you’re wrapped in a warm blanket.

It’s creamy, cheesy, and loaded with crispy bacon and green onions—basically all the good stuff in one bite. I made this for a family potluck once, and it disappeared so fast that people were scraping the dish for more.

It’s one of those recipes that brings everyone together, whether it’s a holiday dinner or just a cozy Sunday night.

What I love most is how easy it is to prep ahead. You can bake the potatoes and cook the bacon the day before, then just assemble and bake when you’re ready.

Tips that will ease your job!

  • Use Russet Potatoes – Russet potatoes have a high starch content, making them perfect for a fluffy, creamy texture. Avoid waxy potatoes like red or Yukon Gold for this recipe.
  • Bring Ingredients to Room Temperature – Let the butter, sour cream, and milk sit out while the potatoes bake. This helps them blend smoothly into the potatoes without curdling.
  • Don’t Overmash – Overmashing the potatoes can make them gluey. Mash just until creamy for the perfect texture.
  • Save Some Bacon for Topping – Mixing bacon into the potatoes adds flavor, but saving some for the top gives you that crispy, salty bite in every forkful.
  • Cheese Matters – Use sharp cheddar for a stronger flavor, and grate it yourself for better melting. Pre-shredded cheese often contains anti-caking agents that prevent smooth melting.
