I’ve been dying to try these – there are tons of versions, but the one I like best is from Little Spice Jar. It’s so cute! These would be awesome for the upcoming holiday season – bring your own little snacks!
First up is the hardest. Carmelize onions…
Cut an onion in half, the slice into half moons and add to a NOT nonstick pan with butter. After about 5 minutes and they’re softening, add a little thyme and sugar.
Keep stirring the onions around for about 20 minutes.
Add a bit of water if anything starts to burn.
Once they’ve gotten nice brown color, add a dash of balsamic vinegar.
Ok! Put those bad boys into a bowl and then lightly sauté mushrooms.
Unroll the puff pastry and cut one sheet into 9 squares and brush a bit of beaten egg on each.
Add some grated gruyère into the bowl of onions and mushrooms.
Spoon a tablespoon of the mixture to the center of each square.
Bake for about 16 minutes at 425. Et Voila!
