Preparation
Step 1
Bake & mash:
Step 2
Preheat oven to 180°C/350°F.
Step 3
Place potatoes on a foil lined tray. Bake for 1 hour 15 minutes (small) to 1 hour 40 minutes (large) until knife can be easily inserted into the centre.
Step 4
Cool potatoes until they can be handled (but still piping hot inside!) or use tea towel to handle.
Step 5
Browned Butter & crispy sage:
Step 6
Meanwhile, place butter in a large silver saucepan over medium heat.
Step 7
Once melted and starts to foam, add sage leaves. Cook 1 minute or until golden brown, then fish through the foam to find the leaves and drain on paper towels (will crisp when cool).
Step 8
Continue to leave butter on stove until foam dies down and you see black bits on the bottom of the pan (it will smell nutty).
Step 9
Strain through paper towel lined sieve - should have 180ml or so.
Step 10
Topping:
Step 11
Crumble sage leaves in your hand (chop if not fully crisp) and place in bowl.
Step 12
Add 1/4 cup Browned Butter, panko, parmesan, garlic, salt and pepper, mix.
Step 13
Mash:
Step 14
Cut slits down the middle of the potatoes then scoop flesh out into a bowl.
Step 15
Add 1/4 cup Browned Butter (below), sour cream, parmesan, salt and pepper. Mash or use electric beater to mash until smooth (if using food processor, be careful not to overdo as it will make potato gluey).
Step 16
Assemble & bake:
Step 17
Place half the potato in a baking dish (2 litre / 2 quarts). Make swirls across surface with spoon (as catchment for butter!), then drizzle over 1/4 cup Browned Butter. Cover the butter pools with remaining potato - the less you disturb the butter, the better!
Step 18
Sprinkle over Topping. Bake 25 minutes until top is golden brown and edges are bubbling.
Step 19
Sprinkle with crumbled bacon, then bake a further 5 minutes. If you've got any leftover butter, drizzle it on then serve!
