Upside-Down Mushroom Tartlets

Source: Everyday Food, September 2010


  • 1 sheet frozen puff pastry, thawed and cut into six 3-inch rounds
  • 1 tablespoon extra-virgin olive oil, plus more for muffin pan
  • 1 large shallot, diced small
  • 1 pound cremini mushrooms, sliced
  • Coarse salt and ground pepper
  • 2 teaspoons fresh thyme leaves, plus more for serving
  • 3/4 cup grated Gruyere cheese (2 ounces)


  1. Preheat oven to 375 degrees. Place puff pastry rounds in a single layer on a parchment-lined baking sheet and refrigerate while mushrooms cook. In a large skillet, heat oil over medium-high. Add shallot and cook, stirring, until soft, 3 minutes. Add mushrooms and cook, stirring, until soft and browned, 10 minutes. Season with salt and pepper. Stir in thyme and remove skillet from heat.

  2. Lightly oil 6 jumbo muffin cups. Divide mushroom mixture and cheese among cups, then top each with a chilled pastry round. Bake until pastry is golden brown and puffed, about 25 minutes, rotating pan halfway through.

  3. Run a small knife around cups to loosen tartlets. Place a rimmed baking sheet or large plate over pan and invert to release tartlets. Sprinkle with more thyme. Serve warm.

    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.

  • Sheryll 28 Nov, 2010

    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

  • irishmeadow2 23 Sep, 2010

    These were AWESOME!!! I have made them both with this recipe and the swap of grape tomatoes and cheddar. When I made the mushroom ones, I used cheddar and baby portobellos and parsley instead of thyme. They were amazing and I got TONS of compliments! Even from people who don't normally like mushrooms asked for the recipe!! The tomato recipe was not as good as the mushroom one and a bit messier too. I will definately make these again!

    These were simple and delicious! Perfect for a week night meal. Add a salad and you're all set. The only change I made was using an Italian blend cheese. Love them!
