Ingredients

Meatloaf Base:

  • 1 ½ pounds ground beef (80/20 preferred for flavor and moisture)
  • 1 cup breadcrumbs (use panko for a lighter texture or Italian seasoned for added flavor)
  • 1 medium onion, finely diced (adds moisture and flavor to the meat)
  • 2 cloves garlic, minced (optional but highly recommended for a deeper taste)
  • 1 large egg (acts as a binder to hold the meatloaf together)
  • ½ cup milk (keeps the meatloaf moist)
  • 2 tablespoons ketchup (adds tanginess and richness)
  • 1 tablespoon Worcestershire sauce (enhances the umami flavor)
  • 1 teaspoon salt (adjust to taste)
  • ½ teaspoon black pepper
  • ½ teaspoon smoked paprika (for a subtle smoky kick)

Loaded Potato Topping:

  • 4 cups mashed potatoes (use leftovers or freshly mashed; russet or Yukon gold are ideal)
  • ½ cup sour cream (adds creaminess and tang)
  • 4 tablespoons butter (melted, for smooth texture)
  • ½ cup shredded cheddar cheese (gives a cheesy flavor boost)
  • ½ cup cooked and crumbled bacon (provides crunch and savory depth)
  • 2 green onions, thinly sliced (for a pop of freshness)
  • Salt and pepper to taste

the Topping:

  • 1 ½ cups shredded cheese (cheddar, Monterey Jack, or a blend for maximum meltiness)
  • ¼ cup cooked bacon bits (for extra bacon goodness)
  • 2 tablespoons fresh parsley, chopped (optional, for garnish)

Instructions

1: Preheat the Oven

Begin by preheating your oven to 375°F (190°C). Preparing the oven early ensures an even baking temperature, which is key for a well-cooked casserole. Lightly grease a 9×13-inch baking dish with cooking spray or line it with parchment paper for easy cleanup.

2: Prepare the Meatloaf Base

  1. In a large mixing bowl, combine the ground beef, breadcrumbs, diced onion, minced garlic, egg, milk, ketchup, Worcestershire sauce, salt, pepper, and smoked paprika. Use your hands or a spatula to gently mix the ingredients until evenly distributed. Be careful not to overmix, as this can result in a tough meatloaf.
  2. Transfer the meat mixture to the prepared baking dish and press it into an even layer. Make sure to pack it down gently to create a solid base for the casserole while avoiding compacting it too much.

3: Prepare the Loaded Potato Topping

  1. If you’re using fresh potatoes, boil them until fork-tender, then mash them with a potato masher or mixer until smooth. Stir in sour cream, butter, and shredded cheddar cheese until fully incorporated. For an even creamier texture, you can use a hand mixer at low speed.
  2. Fold in the crumbled bacon and green onions, then taste and adjust the seasoning with salt and pepper. This step ensures your mashed potatoes are flavorful on their own, elevating the entire dish.
  3. Spread the mashed potato mixture evenly over the meatloaf layer. Use a spatula to smooth it out, ensuring every corner is covered for a consistent bite.

4: Add the Toppings

  1. Sprinkle the shredded cheese evenly across the top of the mashed potatoes. The cheese layer will create a gooey, golden crust when baked.
  2. Scatter the bacon bits over the cheese layer. This adds a satisfying crunch and enhances the dish’s savory notes.

5: Bake the Casserole

  1. Place the casserole in the preheated oven and bake for 35–40 minutes, or until the meatloaf layer is cooked through. To ensure it’s done, insert a meat thermometer into the center of the meatloaf—the internal temperature should reach 160°F (71°C).
  2. For an extra layer of texture and visual appeal, switch the oven to broil for the last 2–3 minutes of baking. Keep a close eye to avoid burning, and remove the casserole when the cheese is bubbly and slightly golden.

6: Rest and Serve

  1. Allow the casserole to rest for 5–10 minutes after removing it from the oven. This resting period helps the layers set, making it easier to slice and serve.
  2. Garnish with freshly chopped parsley for a pop of color and freshness, then serve warm. Pair with a side salad or roasted vegetables for a complete meal.

Tips

  • Don’t Skip the Resting Time: Letting the casserole rest after baking allows the layers to firm up, making for neater slices.
  • Ensure Even Layers: Spreading the meatloaf and potato layers evenly ensures every serving is balanced and visually appealing.
  • Use a Meat Thermometer: This ensures the meatloaf base is fully cooked without overbaking.

Storage Instructions

Refrigeration:

Store leftovers in an airtight container in the refrigerator for up to 3–4 days. For best results, reheat in the oven to maintain the casserole’s texture.

Freezing:

Wrap the entire casserole tightly in aluminum foil or plastic wrap and freeze for up to 2 months. Thaw in the refrigerator overnight before reheating.

Reheating:

  • Oven: Reheat at 350°F for 20–25 minutes, or until warmed through. Cover with foil if reheating a large portion to prevent drying out.
  • Microwave: Heat individual servings in a microwave-safe dish for 1–2 minutes, checking and stirring halfway through.

Variations

  1. Low-Carb Option: Use mashed cauliflower instead of potatoes for a lighter, low-carb version.
  2. Mexican-Inspired Twist: Incorporate taco seasoning into the meatloaf base and top with jalapeños and pepper jack cheese.
  3. Vegetarian Version: Replace the meatloaf layer with a plant-based ground meat substitute and use vegetarian bacon crumbles.
  4. Extra Veggies: Mix in finely chopped carrots, celery, or bell peppers into the meatloaf base for added nutrition and flavor.
  5. Sweet Potato Mash: Swap traditional mashed potatoes with sweet potatoes for a sweet and savory contrast.
