Sunday Supper: Butternut and Sweet Leek Hash

Serves 2 or, with eggs, 4.

Note: Use any leftover cooked root vegetables in this hash. From "A Modern Way to Cook," by Anna Jones.

• 2 leeks

• 1 tbsp. coconut or olive oil, divided

• 14 oz. new potatoes, unpeeled

• 1/2 medium butternut squash

• A few fresh chives

• A few sprigs of fresh parsley, with more for garnish

• 4 tbsp. crème fraîche or yogurt

• Juice of 1/2 lemon

• Sea salt and freshly ground pepper

• A crumble of Cheddar cheese, optional

• 4 eggs, optional

Directions

Bring a kettle of water to boil. Put a large nonstick pan over medium heat.

Meanwhile, wash the leeks, then finely slice them and add them to the pan with a little of the coconut oil. Stir every couple of minutes.

While leeks are cooking, cut the potatoes into 1/2-inch pieces and put them into a large saucepan. Add enough of the boiling water from the kettle to cover them, and bring water back to a boil, then turn down the heat and simmer for 5 minutes.

Peel and seed the squash, and cut into pieces about the same size as the potatoes. Once the potatoes have had 5 minutes in the boiling water, add the squash to the pan of potatoes, adding more water if necessary, bring back water to a boil and cook vegetables for 3 more minutes. Make sure the potatoes and squash have softened a little, drain them and leave in the colander to steam-dry a bit.

Set aside 3 tablespoons leeks in a bowl. Turn heat up under the leek pan, add a little more oil if necessary, then add potatoes and squash with the remaining leeks and fry, turning every couple of minutes, but not too often — you want to allow each side enough time to build up a bit of a golden crust.

Make dressing while potatoes and squash cook by chopping the herbs and adding them to the reserved 3 tablespoons leeks. Add crème fraîche or yogurt, the lemon juice, and some salt and pepper, and blend well, using a handheld blender. Set aside.

Keep turning hash in pan until it's all nicely golden. You can serve it like this. Or you can crumble a little cheese over the top and melt it. Then crack the eggs into the pan, pop a lid on top, and allow them to cook for 3 to 5 minutes until the whites are set but the yolks are still runny.

Serve the hash with dressing drizzled over. Garnish with parsley.
