2 cloves garlic, minced
2 large eggs
1/2 cup whole milk
1 teaspoon Worcestershire sauce
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
1/2 teaspoon smoked paprika
2 pounds ground beef (80/20 is ideal for flavor and moisture)
1 cup plain breadcrumbs (or gluten-free panko)

For the Loaded Potato Topping:

2 ½ pounds russet potatoes (about 3-4 large potatoes), peeled and quartered
4 tablespoons unsalted butter
1/2 cup whole milk, warmed
1/2 cup sour cream
1 teaspoon kosher salt
1/2 teaspoon garlic powder
1 ½ cups shredded sharp cheddar cheese, divided
6 slices bacon, cooked until crisp and crumbled
2 tablespoons fresh chives, chopped

Step-by-Step Instructions

Level of Difficulty: Medium

Preheat & Prep: Preheat your oven to 350°F (175°C) . Lightly grease a 9×13-inch baking dish with non-stick spray or a little oil.
Start the Potatoes: Place the peeled and quartered potatoes in a large pot and cover with cold water by about an inch. Add a generous pinch of salt. Bring to a boil over high heat, then reduce to a simmer and cook for 15-20 minutes, or until the potatoes are fork-tender.
Sauté Aromatics: While the potatoes are boiling, heat the 2 tablespoons of olive oil in a small skillet over medium heat. Add the finely chopped onion and cook until softened and translucent, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant. Remove from heat and set aside to cool slightly.
Make the Meatloaf Mixture: In a large bowl, whisk together the eggs, 1/2 cup milk, Worcestershire sauce, 1 teaspoon salt, 1/2 teaspoon pepper, and smoked paprika. Add the ground beef, cooled onion mixture, and breadcrumbs. Use your hands to gently mix everything until just combined. Be careful not to overmix, as this can make the meatloaf tough.
Form the Base: Transfer the meat mixture to the prepared baking dish. Gently press it into an even layer, covering the bottom of the dish.
Mash the Potatoes: Once the potatoes are tender, drain them well in a colander. Return them to the hot pot and let them sit for a minute to steam dry. Add the butter, warm milk, sour cream, 1 teaspoon salt, and garlic powder. Mash until smooth and creamy. Taste and adjust seasoning if needed.
Assemble the Casserole: Spread the mashed potatoes evenly over the raw meatloaf base. Sprinkle the top with 1 cup of the shredded cheddar cheese.
Bake: Place the casserole in the preheated oven and bake, uncovered, for 45-55 minutes. You’ll know it’s done when the meatloaf is cooked through (an instant-read thermometer inserted into the center of the meatloaf should read 160°F) and the potato topping is lightly golden.
Add Final Toppings: Carefully remove the casserole from the oven. Sprinkle the remaining 1/2 cup of cheddar cheese and the crumbled bacon over the top. Return to the oven for another 5 minutes, just until the cheese is melted.
Rest & Serve: Remove from the oven and let the casserole rest for at least 10-15 minutes before slicing and serving. This crucial step allows the juices to redistribute, ensuring a moist meatloaf. Garnish with fresh chives right before serving.

Recipe Tips & Tricks

Don’t Overmix: When combining the meatloaf ingredients, mix just until they come together. Overworking the meat will result in a dense, tough loaf.
Potato Perfection: For extra creamy potatoes, warm the milk and butter before adding them. This helps them incorporate more smoothly.
Check for Doneness: Ovens vary, so the best way to ensure your meatloaf is cooked perfectly is to use an instant-read thermometer.
Resting is Key: Don’t skip the resting period! If you cut into it immediately, all the flavorful juices will run out onto the cutting board instead of staying in the meatloaf.

Make Ahead & Storage

Make Ahead: You can assemble the entire casserole (steps 1-7) up to 24 hours in advance. Cover the dish tightly with plastic wrap and refrigerate. When ready to bake, you may need to add an extra 15-20 minutes to the baking time since you’ll be starting from cold.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.
Reheating: Reheat individual portions in the microwave or place larger portions in a 350°F oven, covered with foil, until warmed through.
Freezing: This casserole freezes well. Assemble and bake as directed, then let it cool completely. Wrap the entire dish (or individual portions) tightly in plastic wrap and then foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
