# How to Make It:
01 -
Heat a large skillet over medium heat. Add ground beef, diced onion, and minced garlic. Cook until meat is well browned and onions are softened, stirring regularly. Drain excess fat if necessary.
02 -
Stir in tomato paste and cook for 2–3 minutes. Add garlic herb seasoning, Worcestershire sauce, beef bouillon, and water or broth. Mix thoroughly, reduce heat, and allow the mixture to simmer gently.
03 -
Microwave peeled and chopped potatoes for 8 minutes until slightly tender, or parboil in simmering water for approximately 5 minutes. Drain if needed.
04 -
Toss softened potatoes with olive oil and onion soup mix in a 33x23 cm (9x13 inch) baking dish. Spread potatoes evenly across the base. Spoon the beef mixture over the potatoes, creating an even layer.
05 -
In a bowl, whisk cream of mushroom soup, milk, and black pepper until fully blended.
06 -
Pour the prepared cream sauce over the casserole. Cover dish tightly with foil and bake in a preheated oven at 190°C (375°F) for 35 minutes.
07 -
Remove foil. Sprinkle grated cheese and crispy fried onions evenly over top. Return casserole to the oven and bake uncovered for an additional 7–10 minutes until cheese is thoroughly melted and onions are golden.
08 -
Allow casserole to rest for 5 minutes before slicing and serving.
# Extra Information:
01 -
Parboiling or microwaving the potatoes prevents them from remaining undercooked during baking, ensuring a tender final dish.
