First tasted this dish in the Austrian Alps after a hard day in the snow. We call it Tyrolla Grosser because it can be quite filling. Had to try and make it at home. Great tummy pleaser after a cold day, frequently cooked during winter months. As in most of my recipes, quantities can be altered, but I have made so many variations of this. This is the basic.
Fantastic way to use up boiled potatoes. Not looking for potatoes to brown in final stage but it doesn't matter if they do. Have cooked this as an alternative to an English breakfast. Just add brown sauce and grated cheese for a variation.
Results can depend on type of potato. Sometimes it holds together but sometimes the potatoes break up. Tastes just as gorgeous either way. Have found steaming is the better way so the potatoes don't get too watery.
Cooking the onions in the microwave saves time. I use this method for all my recipes now. Place them in a microwavable plastic bag with knob of butter. Loosely tie and cook on full for 2 to 3 minutes. Use bursts of 30 seconds if longer is required. Picked up this tip from a burger van of all places!
