Prep and initial bake
- Preheat oven to 350°F and grease a 9x13 baking dish. Make sure the dish is well coated so the meatloaf releases cleanly.
- Mix the ground beef, breadcrumbs, eggs, milk, grated onion, Worcestershire, salt, and pepper until evenly combined. Press the mixture into the baking dish into a loaf shape with compact, even sides and a flat top.
- Bake at 350°F for 45 minutes, until nearly cooked through. The loaf should look set on top but still need finishing time after the potatoes go on.
Make the cheesy mashed potatoes
- Mash the boiled Yukon gold potatoes with butter, warm cream, 1 cup cheddar, salt, and pepper until smooth. Stop when the texture is creamy with no lumps.
- Spread the mashed potatoes thickly over the meatloaf top. Scatter the remaining cheddar over the potatoes so it melts into a golden layer.
Finish and rest
- Return to the oven and bake at 350°F for 15–20 minutes. Bake until the potato topping is golden and the cheese is bubbling.
- Rest for 10 minutes before serving. This helps the slice hold together so the cheesy topping stays intact.
Notes
Pro tip: grate the onion finely so it blends into the meatloaf without watery pockets. Refrigerate leftovers in an airtight container for up to 3 days; reheat slices at 350°F until warmed through. Freezing is yes—freeze cooked portions for up to 2 months and thaw overnight in the fridge. For a lighter option, use lean ground beef (90% or higher) and reduce the cheddar slightly while keeping the topping thick.
