2. Make the Meatloaf Mixture

In a large mixing bowl, combine the ground beef, chopped onion, minced garlic, breadcrumbs, milk, egg, Worcestershire sauce, salt, and black pepper. Mix everything gently but thoroughly. Press the mixture evenly into the bottom of the prepared baking dish.

Pro Tip:

Don’t overmix the meat—doing so can make it tough. Mix just until everything is combined.

3. Add the Ketchup Layer

Spread the 1/2 cup of ketchup evenly over the top of the meatloaf. This not only adds flavor but helps create a nice glaze.

4. First Bake

Place the baking dish in the oven and bake for 25 minutes. This step allows the meatloaf to start setting up before the potato layer is added.

5. Prepare the Potatoes

While the meatloaf is baking, bring a pot of salted water to a boil and add your peeled, sliced potatoes. Cook for about 15 minutes, or until the potatoes are fork-tender. Drain and return to the pot.

Add the sour cream, milk, and butter. Mash until smooth and creamy. Season with salt and pepper to your taste.

6. Assemble the Casserole

After the initial 25 minutes of baking, remove the meatloaf from the oven. Carefully spread the mashed potatoes over the meatloaf layer.

Sprinkle the shredded cheddar cheese evenly over the top, followed by chopped green onions.

7. Final Bake

Return the dish to the oven and bake for another 20 minutes, or until the cheese is melted, bubbly, and golden.

8. Rest and Serve

Let the casserole rest for 10 minutes before slicing. This helps everything set and makes serving easier.

Serving Suggestions

This casserole is rich and satisfying on its own, but here are a few simple sides that pair beautifully:

Steamed green beans with a touch of lemon zest
Roasted carrots or Brussels sprouts
A crisp garden salad with a tangy vinaigrette
Garlic bread for extra indulgence

Storage and Reheating Tips

Storage:

Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. This casserole actually gets better the next day as the flavors continue to meld.

Freezing:

Yes, you can freeze it! Once fully baked and cooled, wrap the casserole tightly in foil and plastic wrap. Freeze for up to 3 months. Thaw overnight in the fridge before reheating.

Reheating:

To reheat, cover with foil and warm in a 350°F (175°C) oven for about 20-25 minutes, or until heated through. You can also microwave individual portions.

Tips for Success

Use starchy potatoes like Russets or Yukon Golds—they mash up creamy and hold up well when baked.
Grate your own cheese if possible. Pre-shredded cheese often contains anti-caking agents that prevent smooth melting.
Add mix-ins like cooked bacon bits or a dash of hot sauce to the mashed potatoes for extra flavor.
Make it low-carb by swapping mashed cauliflower for the potato layer.

Make It Your Own: Variations to Try

1. BBQ Twist

Replace ketchup with barbecue sauce for a smoky, tangy spin on the classic.

2. Tex-Mex Style

Add a tablespoon of taco seasoning to the meat mixture and top the casserole with shredded Mexican cheese blend and a sprinkle of jalapeños.

3. Italian-Inspired

Mix some marinara sauce into the beef and top the potatoes with mozzarella and Italian herbs.

4. Veggie Boost

Sneak in finely chopped carrots, mushrooms, or bell peppers to the meatloaf mix for added nutrition.
