Batatas boulangère fáceis

Ingredientes

• 1 small brown onion, or 1/2 a large one
• 450 g (1 lb) potatoes
• freshly ground sea salt & black pepper
• 300 ml (1 1/4 cups) beef, chicken or vegetable stock
• unsalted butter

Modo de preparo

1. 1

   Pre-heat the oven to 200 degrees (390F) and butter a medium baking dish.

2. 2

   Peel and thinly slice the onion and the potatoes.

3. 3

   Layer the potatoes, then a little onion, then some seasoning until you’ve run out of everything and the dish is filled.

4. 4

   Pour over the stock – it should reach to just below the potatoes – if not, add a little more or a little water from the kettle. Dot the top of the potatoes generously with more butter and season again.

5. 5

   Cover with foil and bake for 30 minutes; the potatoes should be just starting to become tender.

6. 6

   bake for another 45 minutes until the potatoes are tender and the top has crisped.
