An overhead shot of a bubbling Loaded Baked Potato Casserole fresh from the oven, captured in warm natural light that highlights the golden, slightly crispy cheese topping. The casserole is served in a rustic ceramic baking dish placed on a weathered wooden table, with steam gently rising from its surface. A cross-section view reveals layers of creamy mashed potatoes studded with bacon bits and green onions. The vibrant colors contrast beautifully—the white, fluffy potato base, red-brown bacon pieces, bright green chives sprinkled on top, and the amber melted cheese creating an appetizing crust. Small ramekins of sour cream and extra bacon bits sit alongside, suggesting optional toppings for serving.

Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 180°C (fan 160°C) and lightly grease a 20 x 25cm baking dish. Place the peeled and cubed potatoes in a large pot and cover with cold water. Adding cold (rather than hot) water helps the potatoes cook evenly from the inside out. Add a generous pinch of salt to the water.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Bring the potatoes to a boil, then reduce the heat and simmer for 15-20 minutes until they're fork-tender. Be careful not to overcook them as they'll become waterlogged and make your casserole soggy.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>While the potatoes are cooking, cook your bacon until crisp in a frying pan. The slow rendering of fat creates the best flavor and texture. Once cooled, crumble into small pieces. Reserve a small amount for the topping if desired.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Drain the potatoes thoroughly in a colander, then return them to the hot pot. Allow them to sit for 1-2 minutes, gently shaking the pot occasionally. This dry-out step is crucial for removing excess moisture, resulting in fluffier mashed potatoes.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Add the warm milk, butter, and sour cream to the potatoes. The warmth of the milk prevents the potatoes from cooling too quickly, which would make them gluey. Mash until smooth but still with some texture – you're not aiming for completely smooth purée as some texture adds character to the casserole.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Fold in half of the grated cheese, most of the bacon (reserving some for topping), three-quarters of the spring onions, the minced garlic, salt, pepper, and paprika. Mix gently but thoroughly. Taste and adjust seasoning – potatoes often need more salt than you might expect.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Transfer the potato mixture to your prepared baking dish, spreading it evenly with a spatula. Top with the remaining cheese and reserved bacon. The cheese creates a protective layer that helps retain moisture while developing a beautiful golden crust.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Bake uncovered for 25-30 minutes until the cheese is melted and golden brown and the edges are bubbling. For an extra crispy top, switch to the grill/broiler for the last 2-3 minutes, watching carefully to prevent burning.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Remove from the oven and let stand for 5-10 minutes before serving. This resting time allows the flavors to meld and the casserole to set slightly. Sprinkle with the remaining spring onions and fresh chives just before serving for a burst of color and fresh flavor.</li></ol>

What ingredients are used in Loaded Baked Potato Casserole?

This comfort dish combines potatoes, sour cream, cheddar cheese, crispy bacon, spring onions, chives, garlic, butter, milk, salt, pepper and paprika. These ingredients create layers of flavour, replicating the popular loaded baked potato toppings in a shareable casserole form.

How to cook Loaded Baked Potato Casserole at home?

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.

Can I prepare potato casserole in advance for a dinner party?

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.

What's the secret to achieving fluffy mashed potatoes in a casserole bake?

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.

What can I add to a potato bake to create different flavour variations?

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.
