Easy Brussels Sprouts and Chestnut Quiche

Brussels Sprouts and Chestnut Quiche

Christmas day is just over and like many other families you are probably sitting on lots of leftovers. We all know that hardly any vegetable polarises as much as Brussels Sprouts, you either love them or hate them.

Nonetheless, they are a staple of most Irish or British Christmas dinners. Personally, I love them and here is my solution for those leftover Brussels sprouts, Brussels sprouts and chestnut quiche to the rescue!

It is an easy and wonderful dish that can be served either hot or cold. Brussels sprouts are a nutritious winter vegetable and are delicious anytime, not just after Christmas day.


Benefits of Brussels Sprouts

  • They are a great source of folic acid, potassium, fibre and vitamin C.
  • Vitamin C is important to help wounds heal, protect cells and keep the immune system working.
  • However, vitamin C is a water-soluble vitamin that will leach into the cooking water if you cook sprouts for too long, so cook them quickly in boiling water for no more than minutes.
  • Even better than cooking is steaming them, which is my prefered method.

How to make quiche pastry

  • It is as simple as mixing flour, butter, water and salt together but the secret is that the dough needs to be chilled.
  • It’s important that the quiche crust is cold when filled and baked. The cold dough should not lose its shape when pressed. When the butter within the dough gets cold it helps keep the thin layers of flour/water separated which is exactly what’s needed to achieve a beautiful flaky quiche crust!
  • If you have always been struggling with soggy pie or quiche crusts you might want to blind bake them. I am always too busy, so I usually skip that step. It sometimes might be slightly softer in the middle but they have never been that soft that they wouldn’t have held together.
  • But if you are a perfectionist you might want to blind bake the pastry. Heat the oven to  425 °F/220 °C. Cut a large piece of baking parchment, then scrunch into a ball. Open it out and line the chilled pastry case with it. Now fill it with dried beans, lentils or rice, they are just being used as a weight to prevent the pastry from puffing up. Use enough beans to press against the sides, to support the pastry wall when baking.
  • Bake it on a baking sheet for 15-20 mins until the sides are crisp and set. Remove from the oven and carefully lift the paper and beans out. Return the pastry to the oven and cook for another 5 mins or until the base and sides are golden and crisp.

How to make the quiche filling


After many attempts and burned fingertips, I have given up on roasting chestnuts myself. I simply buy them roasted and peeled from an Asian market. They are vacuum packed and don’t contain any additives. You can easily crumble them up between your fingers or quickly chop them with a knife.

Brussels sprouts

Feel free to buy them in whatever form you like. If you have leftover Brussels sprouts you can simply skip the step of cooking them. As mentioned above, I prefer steaming mine over boiling them in water to preserve Vitamin C. If you use frozen Brussels sprouts just make sure to allow enough time for them to thaw completely.

Pancetta or cooked ham

Either of the two is fine, just make sure to dice them finely. I personally prefer the flavour of pancetta, if you would like to add an extra layer of flavour you can quickly brown them in a pan but it is perfectly fine to skip that step.

In case you want to turn this dish into an ovo-lacto vegetarian version you can simply omit the pancetta or replace it with smoked tofu cubes.

Egg mixture

From here on it is as simple as mixing the eggs, creme fraiche and spices together and pouring it into the pie dish and baking it for about 25 minutes. The egg mixture is the same for most quiches, so feel free to get creative with the filling.

You don’t want to overbake it, bake it until it is just set and the corners start to brown. Let it cool for about 10 minutes and then serve it either hot or cold.

  • 1 cup white spelt flour organic
  • 1 cup wholemeal spelt flour organic
  • 1/2 stick butter
  • 1 teaspoon sea salt
  • 1/4 cup water cold


  • 1 1/2 cups chestnuts roasted, peeled and roughly chopped
  • 2 cups water
  • 1 pound Brussels sprouts fresh or frozen and thawed, cut in half
  • 5 ounces pancetta or ham, finely diced
  • 14 ounces creme fraiche
  • 4 eggs organic
  • 1 1/2 teaspoons sea salt
  • 1 teaspoon pepper
  • 1/2 teaspoon nutmeg


  • In a big bowl, mix all the ingredients for the crust until well combined. Shape the dough into a ball, cover it with cling film and chill it in the refrigerator while you continue with the recipe.
  • Add the water to a saucepan and bring it to a boil. Steam your Brussels sprouts for 10-15 minutes or until slightly soft. If you don't have a steam basket you can also quickly parboil them instead. 
  • Meantime, preheat the oven to  425 °F/220 °C. Grease your pie dish with butter, roll out the dough on a lightly floured surface until it's about the hight of a €1 coin. Carefully transfer it to the greased baking pan. Make sure to press the dough into the dish and to pull up the sites by about an inch or a minimum of 2cm.
  • Place the steamed/cooked Brussels sprouts, pancetta and chestnuts on top of the crust. 
  • In a medium-sized bowl, mix together the remaining ingredients and pour them over the filling.
  • Bake for about 25 minutes or until lightly browned and set. Cut into 8 slices and serve hot or cold.
