Ingredients for this Cheesy Meatloaf Casserole

2 large eggs
1/2 cup milk
1 small yellow onion, finely diced
2 cloves garlic, minced
1/3 cup ketchup
2 tablespoons Worcestershire sauce
1 1/2 teaspoons salt
1 teaspoon black pepper
1 teaspoon dried Italian seasoning
2 tablespoons olive oil (for cooking the onion and garlic)

1/2 cup milk (for potatoes)

For the cheesy topping and garnish

2 cups shredded cheddar cheese
2 tablespoons chopped fresh parsley (optional, for serving)

Instructions

Set aside about an hour from start to finish. Most of that time is hands-off while the Cheesy Meatloaf Casserole bakes and the house starts to smell like dinner.

Preheat the oven and prepare the dish.
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set it aside. This will help the meatloaf layer release easily and keep the potatoes from sticking.
Cook the potatoes.
Place the peeled and cubed russet potatoes in a large pot and cover them with cold water. If you like, add a small pinch of salt. Bring the pot to a boil over medium-high heat. Once boiling, reduce the heat to a gentle boil and cook for about 12–15 minutes, or until the potatoes are tender when you poke them with a fork.
Soften the onion and garlic.
While the potatoes are cooking, heat the olive oil in a skillet over medium heat. Add the finely diced yellow onion and cook for 3–4 minutes, stirring occasionally, until it softens and turns slightly translucent. Add the minced garlic and cook for another 30 seconds, just until fragrant. Take the skillet off the heat and let the mixture cool for a few minutes so it does not scramble the eggs in the meat mixture.
Mix the meatloaf base.
In a large mixing bowl, combine the ground beef, plain breadcrumbs, eggs, 1/2 cup milk, ketchup, Worcestershire sauce, salt, black pepper, dried Italian seasoning, and the cooked onion and garlic mixture. Use clean hands or a sturdy spoon to mix everything together just until combined. Try not to overwork it; overmixing can make the meatloaf layer a bit dense.
Form the meatloaf layer.
Transfer the meat mixture to your prepared baking dish. Press it into an even layer across the bottom of the dish, all the way to the edges, forming a flat meatloaf base. It should look a bit like a thick, even burger patty covering the whole pan.
Partially bake the meat.
Slide the baking dish into the preheated oven and bake for 20 minutes. This gives the ground beef a head start so it finishes cooking by the time the potatoes and cheese are nicely browned.
Make the mashed potatoes.
By now, your potatoes should be tender. Drain them well and return them to the warm pot. Add the 3 tablespoons unsalted butter, 1/2 cup milk (for potatoes), 1 teaspoon salt (for potatoes), and 1/2 teaspoon black pepper (for potatoes). Mash until they are smooth and creamy, or leave a few small lumps if you like a more rustic texture. Taste and adjust the seasoning if you feel they need a little more salt or pepper.
Layer the potatoes over the meatloaf.
Carefully take the partially baked meatloaf base out of the oven. Spoon the mashed potatoes over the top in small dollops, then gently spread them into an even layer, covering the meat completely. Try not to press too hard; you want to keep the meat layer in place.
Add the cheese.
Sprinkle the shredded cheddar cheese evenly over the mashed potato layer. Make sure you reach the corners and edges so every bite has some of that melted, cheesy goodness.
Finish baking.
Return the baking dish to the oven and bake for another 20–25 minutes, or until the cheese is fully melted and bubbling and the meat is cooked through. If you like a slightly more golden, toasty top, you can switch the oven to broil for 1–2 minutes at the end, watching closely so the cheese does not burn.
Rest, garnish, and serve.
Once the Cheesy Meatloaf Casserole is done, take it out of the oven and let it rest for about 10 minutes. This short pause helps the layers set a bit, so it slices more neatly. Sprinkle the chopped fresh parsley over the top, if you are using it, then cut the casserole into portions and serve warm.

Frequently asked questions

Can I make this Cheesy Meatloaf Casserole ahead of time?

Yes, you can. A practical way is to assemble the casserole up to the point where you add the mashed potatoes and shredded cheddar cheese on top. Cover the baking dish tightly and refrigerate it for up to 24 hours. When you are ready to bake, let the dish sit at room temperature for about 20 minutes while the oven preheats, then bake until the meat is cooked through and the cheese is melted and bubbly. You may need to add a few extra minutes of baking time since it is starting from cold.

How should I store and reheat leftovers?

Leftover Cheesy Meatloaf Casserole keeps well. Let the casserole cool to room temperature, then transfer the portions to an airtight container and refrigerate for up to 3–4 days. To reheat, you can warm individual pieces in the microwave until hot in the center, or place them in an oven-safe dish, cover with foil, and heat at 350°F (175°C) until warmed through. The mashed potatoes may lose a tiny bit of their fluffiness, but the flavors stay comforting and satisfying.

Can I use a different type of cheese instead of cheddar?

Absolutely. While the recipe uses shredded cheddar cheese for its sharp, classic flavor, you can swap it for another melting cheese if you prefer. Monterey Jack, a mild Colby, or a blend of different cheeses all work nicely. Just keep the same amount of cheese so the texture of the topping stays similar and the Cheesy Meatloaf Casserole keeps its rich, cheesy character.
