It's very, very easy and one that my family love. It’s my most requested ‘can you bring’ item and I’ve only ever stuffed it up once because we were too busy having a good time, ate late and it was a little overcooked and went rather oily.
10 Medium sized new potatoes or 2kgs of tiny chats/new potatoes. Leave the skin on cos that’s where the goodness hides. Boil for about 15-20 minutes until almost cooked but not quite (We in the culinary world call this 'par boiling'). You know they're right when you poke them with something sharp and they feel firm but not crunchy. (That's technical cordon bleuspeak)
Drain and let them cool to touch. Otherwise you'll burn your phalanges trying to cut them up into neat cubes.I buy the half loin rashers so there’s less fat. Cook until the onions have just begun to sweat. (That means they look a bit more see-through than when they're raw but not burny or brown). Season with freshly ground black pepper. You don’t need salt because the bacon adds saltiness. Add 2 x 200ml tubs of light sour cream. Or if you're thin, use the real shit. Mix through evenly.
In a large frying pan, saute (posh word for fry in a teaspoon of butter) 4 medium onions, roughly chopped with about 10 rashers of lean bacon also roughly chopped.
Cut your 'medium' potatoes into quarters and lay into an oven proof dish . . that's one that won't crack at in the oven. Don't be tempted to use the fine China bowl your Auntie Maud gave you, it will probably crack. If you're using chats, leave them in their little baby entirety. .never chop a chat.Pour the bacony creamy goodness over the top and spread gently with the back of a wooden spoon or spatula.
Sprinkle with a blend of grated parmesan/pecorino cheese (always fresh never that horrible stuff in packets) and a hand full of grated cheddar.Bake on 180 for about 20 minutes
If you’re a vegetarian, you can replace the bacon with virtually any strong flavoured veg. Asparagus is nice but it makes your wee smell funny, or small broccolini florets . . or mushrooms which taste awesome with sour cream.
You can also alternate onions with leeks, the potato’s best friend!
