The Evolution of the American Casserole

Meatloaf and mashed potatoes are two iconic pillars of American comfort food, deeply rooted in resourceful home cooking and designed to be hearty and satisfying. Meatloaf gained popularity as a way to stretch meat during harder economic times, while mashed potatoes have been a beloved side for generations. The “casserole” format, which became incredibly popular in the mid-20th century, particularly in the U.S., offered a convenient way to combine multiple components into a single, bakeable dish, simplifying meal preparation and serving.

The “Loaded Potato” twist takes inspiration from classic loaded baked potatoes, adding elements like bacon, cheese, and sometimes green onions to the mashed potato topping, elevating it beyond a simple side. This Hearty Loaded Potato Meatloaf Casserole creatively fuses these beloved concepts. It takes the familiar, savory meatloaf and tops it with a decadent, “loaded” mashed potato crust, effectively creating a complete meal in one pan. It’s a testament to the enduring appeal of comfort food and the ingenuity of transforming separate dishes into a harmonious, family-friendly masterpiece.


Ingredients

Here’s what you’ll need to create this incredibly hearty and flavorful Loaded Potato Meatloaf Casserole:

For the Meatloaf Base:

  • 1 tablespoon olive oil
  • 1 1/2 lbs ground beef (80/20 lean recommended)
  • 1/2 cup yellow onion, finely diced
  • 1/2 cup bread crumbs (plain or Panko)
  • 1/4 cup milk (whole or 2%)
  • 1 large egg
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

For the Mashed Potato Topping:

  • 2 lbs Russet or Yukon Gold potatoes, peeled and cut into 1-inch chunks
  • 1/2 cup milk (whole or 2%), warmed
  • 1/4 cup (1/2 stick) unsalted butter, melted
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 cup shredded sharp cheddar cheese, divided
  • 6 slices bacon, cooked crispy and crumbled, divided
  • Optional Garnish: Sliced green onions or fresh chives

Swaps and Notes

  • Ground Beef: While ground beef is classic, you can use a mix of ground beef and ground pork, or ground turkey for a leaner option.
  • Bread Crumbs: Plain bread crumbs or Panko bread crumbs work well as a binder. If you don’t have them, you can use crushed Ritz crackers or even a slice of bread soaked in milk.
  • Worcestershire Sauce: This adds a crucial savory, umami punch to the meatloaf. Don’t skip it!
  • Potatoes: Russet or Yukon Gold potatoes are excellent for fluffy mashed potatoes. Cut them into uniform chunks for even boiling.
  • Cheese (Mashed Potatoes): Shred your own cheddar cheese from a block for the best melt and flavor. Pre-shredded often contains anti-caking agents that can make it grainy. You can use mild, medium, or extra-sharp cheddar.
  • Bacon: Cook bacon until it’s extra crispy so it crumbles well and provides a satisfying crunch on top. You’ll use some in the potato topping and some for garnish.
  • Veggies (Meatloaf): For extra nutrition, you can add finely diced bell peppers or mushrooms to the meatloaf mixture after sautéing them with the onion.
  • Meatloaf Glaze (Optional): Some people like a simple glaze on their meatloaf (e.g., ketchup mixed with brown sugar and a splash of vinegar). You can spread this over the meatloaf base before adding the mashed potatoes.

Steps for the Recipe

Let’s assemble and bake this hearty comfort food casserole!

  1. Prepare Meatloaf Base: In a large mixing bowl, combine the ground beef, finely diced onion, bread crumbs, 1/4 cup milk, egg, Worcestershire sauce, garlic powder, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Mix gently but thoroughly with your hands until just combined. Be careful not to overmix, as this can lead to a tough meatloaf.
  2. Form Meatloaf Layer: Press the meatloaf mixture evenly into the bottom of a 9×13 inch baking dish.
  3. Bake Meatloaf (Partially): Bake the meatloaf base in the preheated oven at 375°F (190°C) for 20 minutes. This helps it set before adding the potatoes.
  4. Prepare Mashed Potatoes: While the meatloaf bakes, place the peeled and diced potatoes in a large pot and cover with cold water by about 1 inch. Add a pinch of salt to the water. Bring to a boil, then reduce heat to medium and simmer for 15-20 minutes, or until the potatoes are very tender when pierced with a fork.
  5. Mash Potatoes: Drain the cooked potatoes thoroughly. Return them to the hot pot. Add the warmed 1/2 cup milk, melted 1/4 cup butter, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Mash with a potato masher until smooth and creamy.
  6. Load Potatoes: Stir in half of the cooked, crumbled bacon and 1/2 cup of the shredded sharp cheddar cheese into the mashed potatoes until well combined.
  7. Assemble Casserole: Remove the partially baked meatloaf from the oven. Carefully spoon the loaded mashed potato topping evenly over the meatloaf layer, spreading it to the edges.
  8. Final Cheese & Bacon Topping: Sprinkle the remaining 1/2 cup of shredded sharp cheddar cheese over the mashed potatoes. Scatter the remaining half of the crumbled bacon over the cheese.
  9. Bake Casserole: Return the casserole to the oven and bake for an additional 25-30 minutes, or until the mashed potato topping is golden brown, the cheese is melted and bubbly, and the meatloaf is cooked through (internal temperature of 160°F / 71°C).
  10. Rest & Serve: Remove from the oven and let rest for 5-10 minutes before serving. This allows the casserole to set and makes for cleaner portions. Garnish with sliced green onions or fresh chives if desired.

Tips for Success

  • Don’t Overmix Meatloaf: Overmixing can result in a tough, dense meatloaf. Mix just until combined.
  • Thoroughly Drain Potatoes: Watery potatoes will make for soggy mashed potatoes. Ensure they are well-drained after boiling.
  • Warmed Milk/Melted Butter for Potatoes: This helps create smooth, creamy mashed potatoes without lumps.
  • Cook Bacon Crispy: Crispy bacon adds a crucial textural element to the “loaded” potatoes.
  • Resting Time is Key: Allowing the casserole to rest after baking helps the layers set, making it much easier to slice cleanly.
  • Customize Your “Load”: Feel free to add other loaded baked potato toppings to your mashed potatoes like a dollop of sour cream (stirred in with the milk/butter) or finely chopped chives.

Serving Suggestions and Pairings

Hearty Loaded Potato Meatloaf Casserole is a complete and satisfying meal on its own, but it pairs beautifully with:

  • Simple Side Salad: A light, crisp green salad with a vinaigrette dressing provides a refreshing contrast to the richness of the casserole.
  • Roasted or Steamed Vegetables: A side of roasted green beans, asparagus, or broccoli would be excellent.
  • Warm Dinner Rolls: Perfect for soaking up any extra savory goodness.
  • Other Comfort Foods: This casserole complements other hearty dishes well, such as my This Mexican Chicken and Rice Casserole Is My Favorite One-Pan Dinner That’s Always a Hit.
  • Beverage Pairings: A simple glass of water, iced tea, or a medium-bodied red wine (like a Merlot or Zinfandel) would complement this casserole nicely.

Storage and Leftover Tips

Hearty Loaded Potato Meatloaf Casserole makes fantastic leftovers, often tasting even better the next day!

  • Refrigerate: Store cooled leftovers in an airtight container in the refrigerator for up to 3-4 days. The casserole will firm up considerably upon chilling.
  • Reheat: To reheat, gently warm individual portions in the microwave until heated through. For larger portions or to re-crisp the top, reheat in an oven at 300°F (150°C) until warmed through and bubbly.
  • Freezing: This casserole freezes well. Once completely cooled, slice into individual portions. Wrap each slice tightly in plastic wrap, then in aluminum foil. Freeze for up to 2-3 months. Thaw overnight in the refrigerator, then reheat as directed above.
