Onion Mustard Tart

When people here the saying when life gives you lemons, they immediately start thinking about what they’d actually do with said lemons, if life were to give them some.. But what if life gave you onions? Let’s think about this for a moment as well! Some people hate them, but some (most?) do really love them. So let’s take a deep dive into what we’d actually do when life gave us onions.

Well first of all, once they’re peeled, we would cry a little, or a lot if these bastards were really spicy! But once we’d overcome this challenge, they would give us a hell lot culinary joy! I know I know, there are probably quite a few foods you hear me say I could not live without, but onions are life! And I really don’t want to imagine a life without them! 
By now I guess that everyone has understood that I love onions, and it is no surprise that I came up with this onion tart recipe.
Besides onions, there’s another thing that is often added to hearty dishes: mustard. This silky smooth paste instantly refines many dishes with its tangy flavour. I find that it pairs especially well with onions, notably because cooked onions lean on the sweeter side and the mustard just rounds it up so well
We probably do crave more comfort food in winter, but this onion tart is an all rounder. Whether you enjoy it in winter with leafy greens after a warming soup or in summer paired with crunchy and refreshing veggies it will always tickle your taste buds.  
If you have little helpers in your kitchen, delegate the onion cutting to them. This means less tears for you, and more time do concentrate on making the dough. This tart is a perfect weeknight dinner, a lovely dish for picnics in the park or even en entrée when hosting a dinner party at home. As I said, it’s an allrounder! 

For around 6 servings you need:

For the dough:

150g flour

100g cold butter

4 tbsp cold water

salt

For the filling:

25g butter

800g onions

3 tbsp mustard

3 eggs

125g sour cream

30g grated Parmesan

******

In order to prepare the dough, pour the flour   and a pinch of salt on the countertop. Cut the butter into little cubes and add it to the flour. Then start kneading it with your fingertips until you get crumbly dough. Dump the crumbs back on the countertop, mounded high like a mountain. Then at the top push and scrape out the flout until it looks like a volcano. Add the water to this well and knead the dough fairly quickly before forming a ball out of it. Wrap it into cling film and refrigerate for 20 minutes.

After 20 minutes take the dough out of the refrigerator and roll it out. Shape it depending your base and transfer it to it. Now you shall cover the dough with baking paper and refrigerate it once more for 20 minutes.

Preheat the oven to 180°

Take the base out of the fridge and bake for 10 minutes. Take the baking paper off the dough and bake again for 10 minutes until it gets golden brown.

Now you can start preparing the filling by chopping the onions first. Put the butter in your pan. Add the onions and cover them for 10 minutes. Uncover them and cook for another 10 minutes

Spread the baked dough with mustard. Add the onions.  In a middle-sized bowl whisk together the eggs and the cream. Pour this mix over the onions. Finally scatter the tart with the Parmesan.

Bake the tart for 40 minutes

Enjoy!!!!!!!
