I Love onions. All onions. But no raw onion will ever compare to sweet caramelized onions. They tend to be used as toppings rather than the main focus in recipes. So i’m here to change that…. This is an excellent recipe for entertaining guest and it’s versatile for a few reasons.
First, this tart can be served right out of the oven or at room temp & both ways taste great. Second, this can be used at any mealtime! For brunch, with scrambled eggs and fruit, for a light lunch with a nice salad, appetizers at a party or even a side dish for dinner. How awesome is that?! Gruyère cheese can be quite costly so if you can’t find it or don’t want to spend the extra money on it just substitute swiss cheese. You can also make the caramelized onions in advance and store them in the fridge until you are ready to make this. So if you love easy meals and caramelized onions MAKE THIS!
1 pre-made pie dough ( I used pilsbury)
2 cups of caramelized onions
8- 10 oz of shredded Gruyère (or swiss cheese) AND use as much cheese as you want if you feel the need…..
salt & pepper
1 egg -scrambled and a dash of heavy cream or water (egg wash)
Preheat the oven to 350 degrees.
On a sheet of parchment paper unroll the pie dough and smooth out so you have a nice smooth circle of dough.
Sprinkle half of the cheese on the pie dough leaving about a 1 inch border and sprinkle a generous amount of fresh thyme over the cheese. Add the onions and season with salt and pepper. Add the remaining cheese to the top and sprinkle with more fresh time (as much or as little as you want but thyme really is good in this dish)
Gently begin to crimp or pleat the dough around the onions so it forms a little crust. Do this the whole way around the tart being careful not to rip the dough. Brush the entire crust with the egg wash.
Bake for 30-40 minutes or until the crust is golden brown and the cheese is nice and melted. (OH YUM OH YUM) Remove from the oven and add a few sprigs of fresh thyme just because I thought it looked pretty.. Cut it into wedges and serve.
