Ingredients
For the Meatloaf Layer
1½ pounds ground beef (85/15)
¼ yellow onion, finely chopped
⅔ cup seasoned dry breadcrumbs
⅓ cup whole milk
1 large egg, lightly beaten
½ teaspoon kosher salt
¼ teaspoon coarse ground black pepper
For the Mashed Potato Layer

Step‑by‑Step Instructions
Preheat the oven to 350°F (175°C).
In a large bowl, gently combine ground beef, onion, breadcrumbs, milk, egg, salt, and pepper until just incorporated.
Press the mixture evenly into a 9×13‑inch baking dish, forming a smooth layer.
Bake for 25 to 30 minutes until fully cooked and lightly browned.
While the meat bakes, boil the potatoes in salted water for about 15 minutes until fork‑tender.
Drain well and mash with butter, milk, salt, pepper, and parsley until smooth and creamy.
Spread the mashed potatoes evenly over the baked meat layer.
Sprinkle shredded cheddar cheese over the top.
Return the dish to the oven for 10 to 15 minutes until the cheese melts and bubbles gently.
Tips for the Best Texture and Flavor
Avoid overmixing the meat to keep it tender and juicy.
Warm the butter and milk slightly before mashing the potatoes for a smoother consistency.
Let the casserole rest for about five minutes before slicing to maintain clean layers.
Flavor Variations and Simple Add‑Ins
Add cooked bacon bits for a smoky depth.
Use a cheese blend instead of cheddar for a more complex flavor.
Fold roasted garlic into the mashed potatoes for added richness.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to three days.
Reheat in the oven at 325°F, covered with foil, or in the microwave until warmed through without drying out.
