- Highly customizable with cheeses, proteins, and add-ins
Ingredients for the Classic Version
Choosing quality, fresh ingredients is essential for developing the full flavor profile of this dish. Here’s what you will need for a classic twice-baked potato casserole as featured by The Pioneer Woman:
- Russet Potatoes: These are preferred for their starchy texture and flavor that holds up well to baking and mashing.
- Bacon: Thick-cut, smoky bacon adds richness and crunch; add more for garnish if desired.
- Salted Butter: For creaminess and a subtle salty note.
- Sour Cream: Adds tang for balance and lightness.
- Whole Milk: Helps create a smooth, creamy texture.
- Cheddar Cheese: Use freshly shredded for ideal melt and flavor; reserve extra for topping.
- Seasoned Salt + Salt and Pepper: For well-rounded seasoning.
- Green Onions: Sliced; add color and a fresh flavor boost.
- Canola Oil: For coating potatoes during baking.
Note: Some variations use Yukon Gold potatoes, Monterey Jack cheese, or even alternative milks. Red or new potatoes are less ideal, as they can become gluey when mashed.
