01 -
Give your casserole about 5 minutes to chill out before you cut into it and plate up.
02 -
Pop off the foil, throw on the shredded cheese, and put it back in until the cheese looks golden and bubbly, about another 10–15 minutes.
03 -
Cover it tight with foil and bake for 45–50 minutes, just long enough for the potatoes to start getting soft.
04 -
Lay down the rest of your potato slices on top of the meat, dump on what's left of the soup mix, and smooth it around.
05 -
Pour half your soup-milk mix over the beef layer and let it sink in.
06 -
Toss half the potato slices flat in the dish, then pile on the beef and onion blend.
07 -
Take your bowl, stir the soup and milk together really well so it's nice and smooth.
08 -
Heat up a big skillet and brown the beef with the chopped onion. Salt and pepper it, cook till it looks done, then get rid of any extra grease.
09 -
Crank your oven up to 190°C and put a light coating of oil or butter on your 23x33 cm baking dish.
