Ingredients

  • Ground beef: offers a rich hearty base for the casserole choose a blend with a bit of fat for moisture
  • Breadcrumbs: help keep the meatloaf tender and soak up juices opt for fresh or panko for best texture
  • Egg: acts as a binding agent so the meat holds together perfectly
  • Milk: adds moisture making every bite soft and flavorful whole milk gives the best richness
  • Finely chopped onion: brings sweetness and aromatics to the mix use yellow or sweet onion for milder flavor
  • Garlic powder: is the shortcut for savory depth without the fuss of fresh garlic
  • Salt: seasons the base so every layer pops with flavor always taste your mashed potatoes for seasoning too
  • Black pepper: adds a little warmth freshly ground is ideal
  • Worcestershire sauce: is the secret weapon for umami and depth check the label for quality ingredients
  • Ketchup: gives a tangy classic glaze on top choose a ketchup with minimal added sugar if possible
  • Prepared mashed potatoes: create that fluffy top layer homemade works best if you have time
  • Shredded cheddar cheese: melts into ultra gooey goodness sharp cheddar packs more punch
  • Cooked bacon crumbled: for crunchy salty bits the more crispy the better
  • Green onions or chives: add a fresh finish look for bright green stalks without wilt

Instructions

Preheat the Oven:
Get your oven hot at 375 degrees Fahrenheit. Lightly grease a square baking dish. This prevents sticking and encourages the perfect crust around the edges.
Mix the Meatloaf Base:
In a large bowl, combine ground beef, breadcrumbs, egg, milk, finely chopped onion, garlic powder, salt, black pepper, Worcestershire sauce, and half the ketchup. Use your hands or a sturdy spoon to mix until all ingredients are just blended. Overmixing can make the loaf tough so stop once the mixture looks even.
Shape and Partially Bake:
Press the meat mixture evenly into your greased dish. Spread it out to cover the bottom. Smooth the top then brush or spoon the remaining ketchup over as a glaze. Bake uncovered for about 20 to 25 minutes until the center is no longer pink and the juices run clear.
Top with Potatoes Cheese and Bacon:
Take the dish out carefully. Spoon the mashed potatoes over the baked meatloaf and gently spread to cover from edge to edge. Sprinkle shredded cheddar evenly. Scatter the crumbled bacon over the cheese for that loaded baked potato feel.
Bake Until Bubbling:
Slide the casserole back in the oven for another 10 to 15 minutes. Watch for the cheese to melt into golden bubbly pockets. The top should look lightly browned and irresistible.
Garnish and Serve:
Take the dish out and let it rest for five minutes. Sprinkle green onions or chives on top for a pop of color and freshness. Slice into squares and serve while piping hot.

When my family made this for the first time bacon became the highlight for my kids. There is something about salty crispy bacon layered over creamy potatoes and cheesy meat that feels like the ultimate comfort. It always brings us to the table smiling.

Storage Tips

Leftovers keep well in an airtight container for up to three days in the refrigerator. Let the casserole cool to room temperature before storing. To reheat microwave individual slices or warm the whole pan covered with foil in the oven to preserve moisture.

Ingredient Substitutions

Ground turkey or chicken are great alternatives if you want to lighten things up. You can use instant mashed potatoes for a quick shortcut but homemade offers the best flavor. Swap in your favorite cheese such as Monterey Jack or pepper jack for variety. If you do not eat pork try turkey bacon or simply omit it.

Serving Suggestions

This casserole pairs beautifully with crisp green beans simple roasted carrots or a fresh green salad to balance the richness. For something extra comforting serve with a tangy apple or cabbage slaw. It always shines as both a main course and part of a family potluck spread.

Cultural and Historical Context

Meatloaf has deep roots in American home cooking cherished for its frugality and ability to stretch simple ingredients. Layering it under mashed potatoes and cheese borrows from shepherds pie traditions and the love of all-in-one hearty casseroles. It is a dish that marries nostalgia with modern ease.

Seasonal Adaptations

In fall experiment by adding sautéed mushrooms or a little pumpkin puree for autumn warmth. During summer lighten the casserole with steamed veggies folded into the mashed potatoes. Use leftover holiday mashed potatoes or cheeses for a perfect post-holiday comfort meal.

Success Stories

Friends have made this for weeknight dinners and it always disappears quickly. My neighbor once swapped cheddar for smoked gouda and said it tasted like a special occasion. It is perfect for gatherings since you can prepare components ahead and assemble before baking.

Freezer Meal Conversion

To make in advance assemble the casserole up to the mashed potato and cheese step. Cover tightly with plastic wrap and foil then freeze for up to two months. Bake from frozen at 350 degrees Fahrenheit adding an extra 20 minutes covered so it heats through without drying out.
