Can you freeze after baking or should you freeze pastry raw then cook?
Hi Dorothy, I would assemble the pastry, then freeze, before baking.
The taste is fantastic and the edge pieces perfect…how can I get the middle of the pastry to puff (or at least cook enough so that it’s not gooey)? I tried prebaking the pastry for 8 minutes before I added the toppings. Maybe I should have done it longer??
Hi Jamie, I think just baking it longer would do the trick, that and making sure the toppings are thinly spread out.
Will parsley or basil work in place of tarragon.
Hi Diana, hmm, not really. If you don’t have tarragon I would crush a few fennel seeds and sprinkle over.
This recipe is great…quick and easy. I reduced the vinegar to 1T and the brn sugar to 1 t. I also added wine to deglaze. Oh, yum! I can see that there could be many variations to this basic recipe, but the onions are a must! Thank you!
This looks so delicious!Right now easy meals are a must, as I have a broken leg and ankle.I’m curious.What were the original amounts of the onion and cheese?
Hi Charlie, I forget what the original amounts were, only that they didn’t work for me.
I want to make this for a party we’re going to for Christmas. Wondering your thoughts on making this ahead – better to bake and then reward at the party or better to prepare and them bake it at the party?
Hi Laura, I would prepare ahead and bake it at the party.
I made this and everyone loved it, it was a hit. I will definitely be making this again. This website is amazing!
This looks really good. Have you ever tried to make puff pastry from scratch? I’m wondering how hard it is…something in my nature, I never like to buy store brand if I can avoid it.
Thanks for the great recipes as usual!
I have not, but here’s an interesting method for making puff pastry from Ashley of Not Without Salt. ~Elise
Thanks for posting this recipe! I found it on Pinterest and I reviewed it right here: http://PinEatReview.com/2012/03/02/caramelized-onion-tart-with-gorgonzola-and-brie/. (Naturally I gave you credit and links throughout.) Thanks again! –Denise
So glad you liked it! ~Elise
I am not a Blue Cheese fan, but made it just as written except a tad more Brie. This was GREAT! Tx!!!
This recipe is fantastic! We used chicken thighs slow cooked in stock and herbes de provence and added chopped spinach to make it a gourmet pizza.
Very, very tasty, despite the fact I don’t like blue cheese and so just doubled the Brie. I couldn’t get fresh tarragon either and had to use dried. Still turned out beautifully.
The majority of the year March through Thanksgiving I can go to my garden in Charlotte, NC and pick fresh tarragon but alas it is January. Given that tarragon grows so prolifically I have gallon bags full of it dried. Would you recommend using dried tarragon and if so whole, crushed or ground?
I would not used dried tarragon. I might crush up some fennel seeds instead. Or just sprinkle the cooked tart with chopped fresh fennel fronds. ~Elise
I’ve just made a batch of this, tastes absolutely fab!
Thank you so much for sharing! This pizza is amazing and I’ve been inspired to feature it in my Friday Food Fetish roundup. If you have any objections, please let me know. Moar, moar, MOAR please :)
Very tasty! I made my own pizza crust, rolled out to about 14″ diam (about the same area as the 10×14 described), and found that using 2 med onions (mine were 3 1/2″ diam) gave a more sparse coverage than I would have liked; I’d recommend 3 med onions next time. I also was not purist about the cheeses; I used a danish blue and some Feta, and served it up as a pizza. It was a great success.
Made this last night and it was delicious! It was easy to prepare and very pretty, too. We used Port Salut cheese in place of the Brie and served with an arugula salad with lemon vinaigrette and French bread. I didn’t notice until afterwards that the dish is intended as an appetizer – we were happy to convert it to an entree!
Tried sprinkling a few pine nuts on top and let brown .. Garnished with small anchovy sprats….yumm yumm.
I don’t see why you couldn’t roll these into palmiers and bake…just as long as they aren’t overfilled they will be fine! Looks delish, can’t wait to try it!
Made this for a New Year’s Eve party and it was insanely good! I followed the recipe above, except I brushed the pastry with a little olive oil and sprinkled some minced roasted garlic over it before adding the other ingredients. The best app at the party, if I do say so myself :D
This was absolutely delicious. I used it with leftover baked ham and pineapple and it was perfect. Easy and definitely will be a repeat addition to my table. Thank You!!!
What kind of puff pastry do you use?? Help!
I use some brand from Whole Foods (can’t remember the name of it) but Marilyn and Jeff use Pepperidge Farm. ~Elise
One of my sons favorite dishes is quite similar to this: I make it into a quiche-like pie using caramelized onions, swiss, bleu cheese and eggs. I use a simple, single pie crust recipe for the bottom. Í’ll have to try this recipe out on him next time! Thanks
To those who inquired about rolling up jelly roll style…I have a similar recipe. Soft brie is spread on puff pastry, topped with caramelized onions, rolled up, and then sliced approx. 1/2″ thick. Place on parchment. Press down slightly to 1/4″, and bake at 400 till golden. Makes a great appetizer.
I’m looking forward to trying this tart version, though…love the combo of gorgonzola AND brie!
We made this last night and it was soooo good! Accidentally forgot the gorgonzola, so next time, and there will be one soon, we’ll add that and maybe even a few walnut pieces. By the way, ours turned out looking EXACTLY like yours. So yummy, thanks Elise!
Wow, I made something extremely similar on Christmas Eve using the Sweet and Sour Onion marmalade from Peter Reinhart’s American Pie. I used puff pastry, too, and topped it with the marmalade, Gruyère, and a buttermilk blue. It was delicious, as I’m sure this is!
I make a very similar “pizza” with thin crispy crust- not puff pastry but I can imagine this would be perfect with the puff pastry. I also make one with very thinly sliced raw potato and Smoked Gouda on a garlic butter crust. I think I will make both of these next weekend with the puff pastry. My mouth is watering.
Oh i know.. this is going to be one of my most favourite flavours ever and I am not kidding. I make caramelised onions with the balsamic and eat it from a bowl! with a spoon … to add the cheeses and herbs would be nirvana.. thanks elise, this is going onto my blog shortly, watch out for the credit!! .. c
It is in the oven and smells AMAZING! Cannot wait to sink my teeth in it. Thanks for another fabulous recipe!
let us know about the jelly roll technique. I would like to serve this for eating out of hand! as opposed to knife and fork! Cheers
You don’t need a knife and fork for this. Just cut them into squares and serve. You can easily pick up with your hand. That’s how I’ve served them, no problem. ~Elise
This looks amazing! One question…would it be possible to roll this up (jelly roll style), slice and bake? Happy New Year, everyone, and thanks to Elise, we’ll be having a tasty New Year, too. So many awesome recipes! Thank you!
Well now that’s an idea. Don’t know if it would work. Haven’t tried rolling up puff pastry jelly roll style. ~Elise
What amazing flavours in this tart!
I must say not only thank you but your recipes are by far the best i can find on the net! Bar none, the food channel, food.com, on and on. I try many touted chef’s recipes and none ever come out as well as yours. If one simply follows the recipe you give you are rewarded with a delicious,spectacular treat. BTW: I adapted your Turkey Meat Balls for a fabulous, delicious dinner.Having cooked down a chicken carcass to a rich full bodied stock with just S&P, Onions and carrots added at the last: I used some in a large skillet added to a flour/butter rue….working it into a rich gravy, (somewhat wet). cooked the meatballs in it turning frequently as they browned, and added more stock as the water evaporated. Finished it with a dash of S&P and ladled it over noodles. WOW! One of the best main dishes I have had in ages. PS: I pre made the balls. Froze them. Using half I defroated on a sheet lined with oiled wax paper on the counter. I am using the rest tonight with your cranberry glaze recipe. If they come out 1/2 as good as the first batch I shall be in Gourmet Heaven. Great blog and thank you so much!
Wondering if Gruyere would work with this recipe, since no one in my house like blue cheese varieties. What are your thoughts for substitutes?
Your guess is as good as mine. I love gruyere, and I love the way that the blue cheese works in this recipe with the other flavors. If you make it with gruyere, please let us know how it works out for you. ~Elise
Thanks for this. Brie is very good on vermicelli, too, with a few toasted walnuts. Either cut off or mince the white rind.
