Learn how to cook Loaded Baked Potato Casserole by boiling peeled potatoes until tender, mashing them with warm milk, butter and sour cream, then folding in cheese, bacon, spring onions and seasonings. Transfer to a baking dish, top with extra cheese and bacon, then bake until golden and bubbling. Rest briefly before serving garnished with fresh herbs.
Yes, this potato casserole is perfect for preparing ahead. Assemble the entire dish up to 24 hours in advance, cover and refrigerate. When ready to serve, allow it to sit at room temperature for 30 minutes, then bake for an additional 5-10 minutes longer than the recipe states to compensate for the cold start.
The key to fluffy mashed potatoes lies in proper potato selection (Maris Piper or Russet), allowing them to dry after draining, using warm (not cold) milk, and avoiding overmixing. The crucial "dry-out" step removes excess moisture, while maintaining some texture rather than overworking into a gluey consistency.
Create exciting variations by adding caramelised onions for sweetness, blue cheese for tanginess, roasted garlic for depth, jalapeños for heat, or pulled pork for a heartier main dish. You can also incorporate herbs like rosemary or thyme, swap cheddar for gruyère, or add a crispy panko breadcrumb topping.
