Look for puff pastry made with actual butter, the flavor is incredible. I made these just as the recipe said mostly , but added 1 large, tiny diced, garlic clove to the shallot. In addition, after sautéing the garlic/shallots, I added a splash of red wine. I used fresh marjoram, as I don't prefer the flavor of thyme I found my pastry not quite cooked through, I made might roll it a tad thinner next time. They were still absolutely delicious, and typically I'm very critical of my own cooking

I've been making these for a couple years and they are a wonderful party appetizer. I lose patience with the cutouts of dough and the muffin tins, so I've been making this on a sheet pan and cutting into squares. Just as delicious and a little less work! I like to cook the mushrooms/shallot mixture and store in the fridge ahead of time... makes quick work day-of. Make sure to drain excess juices before layering on dough.

These are great--I've made them several times in a jumbo muffin tin and a mini-muffin tin. Usually I will use Gruyere and cremini. However, over the holiday we ran out of time to go to the store and used white button mushroom and Swiss, they were good, and we were asked for the recipe (as usual), but there was a noticeable difference.

I made this for NY eve in a round 9" pan. I layered the dough on top. I didn't have the Gruyere cheese or the cremini mushrooms. I used shredded Swiss

No need to freeze for a day, just make ahead and refrigerate til ready to use. It'll be just fine.

Sheryll, Mushrooms do not freeze well, they get mushy and black. At least that has been my experience.

Another on my list for NY's Eve guests. although, they are only getting ONE each, too expensive to buy more cheese. In fact, I might just use Swiss or even Monteray Jack instead of the Gruyere. Depends on cost of cheese next month. Has anyone tried freezing the mushroom mixture for a day or so ahead of time?

I want to make this as a large tart in a round cake pan. I'm thinking I would have to double the recipe - any suggestions on cook time or anything else? Thought this would be a good app for Turkey Day :-)

I made these yesterday and OMG they were amazing. So easy to make and so delicious. I can't wait for my friends to try them at my next dinner party.

Loved these, they will stay in the rotation of meatless dinners. I added a bread salad
