Preheat the oven to 175°C. Lightly grease a 33x23 cm baking dish with cooking spray or oil.
02 -
In a medium skillet over medium heat, crumble and cook the ground beef until browned and no longer pink. Season with salt, pepper, and garlic powder to taste. Use a paper towel to remove excess fat from the pan.
03 -
In a large mixing bowl, combine the cooked beef, frozen cubed potatoes with onions and peppers, cheddar cheese soup, cream of celery or mushroom soup, and half of the shredded cheddar cheese. Add additional seasoning if desired, keeping in mind that the soups already contain salt.
04 -
Transfer the mixture evenly into the prepared baking dish. Sprinkle the remaining shredded cheddar cheese (about 100 grams or more to taste) over the top.
05 -
Cover the baking dish with foil and bake for 30 minutes.
06 -
Remove the foil and bake for an additional 15 minutes, or until the cheese is golden and bubbling. For a more caramelised cheese topping, use the broiler for the last 2–3 minutes if desired.
