Ingredients
The backbone of this casserole is a buttery mash built from Yukon Gold potatoes, which stay creamy even after baking. Crispy bacon adds smoky depth, while sharp cheddar contributes richness and a beautiful melt. A simple breadcrumb‑butter topping supplies that coveted golden crunch, and a handful of fresh herbs lifts the whole dish with bright, aromatic notes.
Main Ingredients
- 2 lb Yukon Gold potatoes, peeled and cubed
- 6 slices thick‑cut bacon, chopped
- 1 ½ cup shredded sharp cheddar cheese
Creamy Mix‑In
- ½ cup whole milk
- ¼ cup unsalted butter, softened
- ½ teaspoon garlic powder
Topping & Seasoning
- ¾ cup panko breadcrumbs
- 2 tablespoons melted butter
- ½ teaspoon smoked paprika
- Salt and freshly ground black pepper, to taste
- 2 tablespoons chopped fresh chives
Together these components create a dish that balances richness with texture. The butter‑infused mash clings to every bite, while the bacon‑cheddar swirl adds depth. The breadcrumb crown turns a simple casserole into a golden, crackly masterpiece, and the chives finish it with a pop of color and a subtle onion‑like freshness.
Step-by-Step Instructions

Preparing the Mashed Base
Place the cubed potatoes in a large pot, cover with cold water, and add a pinch of salt. Bring to a boil, then simmer 12‑15 minutes until fork‑tender. Drain well, return to the pot, and mash with the softened butter, milk, garlic powder, salt, and pepper until smooth and creamy.
Cooking the Bacon & Mixing In Cheese
While the potatoes cook, heat a skillet over medium heat. Add the chopped bacon and cook until crisp, about 5‑7 minutes. Transfer to a paper‑towel‑lined plate, reserving the rendered fat. Stir the shredded cheddar into the hot mashed potatoes, then fold in half of the crispy bacon.
Assembling the Casserole
- Layer the mash. Spread the cheddar‑bacon mash evenly in a greased 9‑x‑13‑inch baking dish, smoothing the top with a spatula.
- Add the remaining bacon. Sprinkle the leftover crispy bacon over the surface for an extra crunch and smoky flavor.
- Prepare the topping. In a small bowl, combine panko breadcrumbs, melted butter, smoked paprika, and a pinch of salt. Mix until crumbs are lightly coated.
- Finish the casserole. Evenly distribute the breadcrumb mixture over the mash. Drizzle any remaining butter from the skillet over the top for a richer crust.
Baking & Serving
Preheat the oven to 375°F (190°C). Bake the assembled casserole for 20‑25 minutes, or until the topping is golden brown and the edges are bubbling. Let it rest for 5 minutes, then garnish with chopped chives before serving hot.
Tips & Tricks
Perfecting the Recipe
Dry the potatoes well. After draining, return them to the hot pot for a minute to evaporate excess moisture; this prevents a soggy casserole.
Use thick‑cut bacon. Its higher fat content yields more flavor and a crunchier texture than skinny bacon.
Season in layers. Add a pinch of salt to the potatoes, then again to the breadcrumb topping; layered seasoning builds depth.
Flavor Enhancements
Stir a teaspoon of Dijon mustard into the mash for a subtle tang, or sprinkle a pinch of cayenne for gentle heat. A drizzle of truffle oil just before serving adds an upscale aroma.
Common Mistakes to Avoid
Don’t over‑mix the mashed potatoes; excess handling makes them gluey. Also, avoid baking at too high a temperature—burnt breadcrumbs mask the delicate cheese flavor.
Pro Tips
Use a hand‑masher. It gives a rustic texture that holds onto cheese and bacon bits better than a food processor.
Cool the mash slightly. Warm mash can melt the cheese too quickly, creating a greasy surface; a few minutes off the heat keeps it firm.
Toast the breadcrumbs. A quick toast in a dry pan before adding butter yields an even richer, nuttier crust.
Finish with fresh herbs. Adding chives or parsley at the very end preserves their bright color and fresh flavor.
Variations
Ingredient Swaps
Swap cheddar for Gruyère or smoked mozzarella for a different melt profile. Use pancetta or turkey bacon if you prefer a milder pork flavor. For a veggie‑centric version, replace bacon with caramelized onions and add roasted cauliflower florets.
Dietary Adjustments
Make it gluten‑free by using gluten‑free panko or crushed cornflakes. For dairy‑free, substitute butter with olive oil and use a plant‑based cheddar alternative. A low‑carb version swaps potatoes for mashed cauliflower and reduces the breadcrumb topping.
Serving Suggestions
Pair the casserole with a crisp green salad dressed in a light vinaigrette, or serve alongside roasted Brussels sprouts for extra texture. A side of apple‑cider slaw adds a sweet‑tangy contrast that brightens the rich casserole.
Storage Info
Leftover Storage
Cool the casserole completely, then transfer to an airtight container. Refrigerate for up to 4 days. For longer keeping, portion into freezer‑safe bags, flatten, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating Instructions
Reheat in a 350°F (175°C) oven, covered with foil, for 20‑25 minutes until heated through; uncover for the last 5 minutes to crisp the topping. In the microwave, heat individual portions on medium power for 2‑3 minutes, adding a splash of milk to restore creaminess.
