Ingredients Needed to Make Delia Smith Boulangere Potatoes

You will need the following ingredients:

  • 2 lb (900 g) potatoes, preferably a floury variety
  • 2 medium onions
  • 2 tablespoons fresh rosemary leaves, plus a few whole leaves for the top
  • Salt and freshly milled black pepper
  • 10 fl oz (275 ml) vegetable stock
  • 5 fl oz (150 ml) milk
  • 1 oz (25 g) butter

You will also need an ovenproof dish measuring 11 x 8 x 2 inches (28 x 20 x 5 cm), lightly buttered.

Instructions to Make Delia Smith Boulangere Potatoes

Step 1: Preheat the oven and prepare the rosemary

Preheat the oven to gas mark 4, 350°F (180°C). Strip the rosemary leaves from the stalks and bruise them in a pestle and mortar. Chop two-thirds of the leaves finely and set aside the rest for later.

Step 2: Slice the onions and potatoes

Cut the onions in half and then slice them thinly. Peel the potatoes and slice them thinly as well, about 1/8 inch (3 mm) thick. You can use a mandoline or a food processor to make this easier.

Step 3: Layer the potatoes and onions in the dish

Arrange a layer of potatoes at the bottom of the dish, slightly overlapping them. Sprinkle some of the chopped rosemary over them, and season with salt and pepper. Then, add a layer of onions, and repeat the process. Continue layering the potatoes and onions, alternating them and seasoning each layer, until you finish with a layer of potatoes.

Step 4: Pour the stock and milk over the dish

Mix the stock and milk together in a jug, and pour it evenly over the potatoes. The liquid should come almost to the top of the potatoes, but not cover them completely. If you need more liquid, you can add some more stock or milk.

Step 5: Dot the butter and scatter the whole rosemary leaves over the top

Cut the butter into small pieces and dot them over the potatoes. Scatter the whole rosemary leaves over the top as well. This will give the dish a nice flavor and a crisp finish.

Step 6: Bake the dish in the oven for 50 to 60 minutes

Place the dish on the highest shelf of the oven and bake for 50 to 60 minutes, or until the potatoes are tender and the top is golden and crisp. You can check the doneness by inserting a knife or a skewer into the potatoes. If it goes in easily, they are done.
