Tools and Preparation

Essential Tools and Equipment

• 9x13-inch baking dish
• Large mixing bowl
• Large pot
• Potato masher
• Small mixing bowl
• Measuring cups and spoons

Why Each Tool Matters

9x13-inch baking dish: Provides the perfect size for layering the meatloaf and mashed potatoes evenly.
Potato masher: Essential for creating smooth, creamy mashed potatoes for the topping.
Large mixing bowl: Allows you to gently combine the meatloaf ingredients without overmixing.

Ingredients

This casserole combines two classic comfort foods into one dish. The meatloaf layer is made with lean ground beef, breadcrumbs, and a savory blend of Worcestershire sauce, mustard, and spices. A sweet-tangy ketchup glaze adds a classic meatloaf finish. The creamy mashed potato topping uses Yukon Gold potatoes for a velvety texture, with butter, sour cream, and garlic powder for extra flavor.

Steps To Create Recipe

Step 1: Prepare the Oven. Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
Step 2: Make the Meatloaf Layer. In a large bowl, combine the ground beef, breadcrumbs, eggs, onion, garlic, Worcestershire sauce, ketchup, Dijon mustard, Italian seasoning, smoked paprika, salt, and black pepper. Mix gently until just combined. Press the mixture evenly into the prepared baking dish.
Step 3: Prepare the Glaze. In a small bowl, whisk together the ketchup, brown sugar, Dijon mustard, and Worcestershire sauce. Spread half of the glaze evenly over the meat mixture. Bake for 30 minutes.
Step 4: Make the Mashed Potatoes. While the meatloaf bakes, place the potatoes in a large pot and cover with cold salted water. Bring to a boil and cook for 15 to 18 minutes, or until fork-tender. Drain well. Mash the potatoes with the butter, milk, sour cream, garlic powder, salt, and black pepper until smooth.
Step 5: Assemble the Casserole. Remove the partially baked meatloaf from the oven. Drain any excess grease if needed. Spread the mashed potatoes evenly over the meat layer. Brush the remaining glaze lightly over the potatoes if desired, or reserve it for serving. Sprinkle the shredded cheddar cheese over the mashed potatoes.
Step 6: Bake Again. Return the casserole to the oven and bake for 20 to 25 minutes, until the cheese is melted and the casserole is bubbling. For a golden cheese topping, broil for 2 to 3 minutes.
Step 7: Serve. Let the casserole rest for 10 minutes before slicing. Garnish with chopped parsley and serve hot.

Tips for the Best Meatloaf Casserole

• Do not overmix the meat mixture to keep it tender.
• Yukon Gold potatoes make extra creamy mashed potatoes.
• Let the casserole rest before slicing for cleaner portions.

• Add a pinch of smoked paprika to the potatoes for extra flavor.
