Ingredients

Why this recipe works

The slow cooker does all the work here, allowing the hashbrowns to slowly absorb the creamy mushroom sauce and ranch seasoning.

This gentle, moist heat ensures the potatoes become perfectly tender without turning mushy. The cheese and butter melt on top, creating a rich, golden crust that adds texture and flavor.

Using frozen shredded hashbrowns is a time-saver, and they hold up beautifully during long cooking. The honey-glazed ham adds a touch of sweetness that balances the savory, tangy ranch and sharp cheddar. This method is foolproof, and the result is a casserole that tastes like it simmered all day.

Notes and substitutions

For the best texture, use shredded hashbrowns (not cubed) and avoid over-stirring once the cheese is added. If your hashbrowns are frozen, you can add them straight from the freezer; just expect a bit more liquid in the casserole. Thawed and patted dry will yield a firmer texture.

This recipe is easily customizable. Swap the ham for cooked bacon or smoked sausage, or use a different cheese like Monterey Jack or Gruyère.

For a vegetarian version, omit the ham and add sautéed mushrooms or bell peppers. The ranch seasoning is key — don't skip it, as it provides the signature flavor.

• shredded russet potato hashbrowns: Frozen shredded hashbrowns (thawed and patted dry) or shredded sweet potatoes for a different flavor.
