Step-by-Step Instructions
- Prepare the Foundation:
- Preheat your oven to 375 degrees Fahrenheit or 190 degrees Celsius and grease a large baking dish to prevent sticking
- Create the Meatloaf Layer:
- Combine ground beef finely chopped onion minced garlic breadcrumbs milk egg Worcestershire sauce salt and pepper in a large bowl Mix thoroughly by hand until just combined and press this mixture into the base of your greased dish Use a spatula to spread ketchup evenly over the top
- Initial Baking:
- Bake the meatloaf layer for twenty five minutes This helps the meat cook through and provides a sturdy bottom for the potatoes
- Prepare the Potatoes:
- While the meatloaf bakes boil your peeled and sliced potatoes in salted water until fork tender about fifteen minutes Drain them well and return to the pot Mash together with sour cream milk and butter Season well with salt and pepper
- Assemble the Final Layers:
- Spread the hot mashed potatoes gently over the partially baked meatloaf layer making sure to cover all edges Sprinkle shredded cheddar cheese and then chopped green onions evenly over the surface
- Complete the Cooking:
- Return the assembled casserole to the oven Bake for another twenty minutes or until the cheese is bubbly and just golden on top
- Rest Before Serving:
