Savory puff pastry at its finest!

I love coming up with recipes that involve caramelized onions and since puff pastry makes a good combo with basically anything (doesn’t it? it does, right?), I was pretty sure these two would make a good match. The brown Creminis add a depth of flavor to the recipe and also add 72 mg of calcium, 100 mcg of folate, and 4.4 mg of zinc to the dish. Yes, yes, there is a lot of butter involved in this recipe, however, keep in mind this is an appetizer and it should serve 8-10 persons. The red onion offers the dish 55 mg of Vitamin C, 172,5 mg of Calcium, 142.5 mcg of folate. So overall, it’s a pretty nutritious appetizer, just stick to the serving size. Or don’t 🗽🎉.

You can make your own puff pastry from scratch using my puff pastry recipe or buy it frozen if you don’t have the time to prepare it at home. Works perfect both ways. You can try out this recipe with different types of mushrooms, such as Portobello, Shiitake, or Oyster mushrooms.

You can make one big puff as I did, or cut the puff pastry dough before adding cremini mixture in 8-10-12 cute individual ones. Totes up to you! 🎈

PUFF PASTRY

By

Puff Pastry Recipe DIYBITES

Aerial and crisp, puff pastry is the richest pastry; still, it’s the lightest. The recipe uses equal quantities of butter and flour. It’s a bit time consuming; however, it doesn’t require plenty of work, only re-rolling it once every 30 minutes. The lemon juice softens the gluten in the flour and makes the dough more supple but measure it carefully, as too much lemon juice can make the pastry difficult to handle 🍋. Try not to chill the pastry longer than 30 minutes between re-rolling it as the butter will harden and can break the dough. If left for longer than 30 minutes, let the puff pastry rest for 10 minutes at room temperature before re-rolling.

It is essential to work on cold surfaces and chill water and butter before using them. The recipe makes enough for two single–crusts for 1.5 liter pie dishes or fifteen 8.5cm vol-au-vents. Both sweet and savory fillings or topping work great. In the picture above I used caramelized red onion and brown creminis to make a delicious and easy appetizer. 🍴😎
