What You'll Need
  • 8 large button mushrooms, sliced thinly
  1. For the pastry crust, cut the butter into small pieces. In an electric mixing bowl, combine the flour and the butter and mix until little ball shapes are formed. Add the salt and water and mix just until the dough comes together. Shape it into a ball with your hands and refrigerate for at least 30 minutes.
  2. Preheat your oven to 350 degrees. Roll out your crust into a thin circle, about ¼ of an inch thick, and lay it in your greased pie/tart pan. Fold a rustic crust, using the edges that hang over and folding them back on top.
  3. Bake for about 15 minutes, until golden. If it starts to puff up, use the back of a wooden spoon to pat it back down. Remove from the oven and prepare the rest of the ingredients.
  4. Put a large skillet on the stove and heat to a very high heat. Once hot, coat the bottom with olive oil, about 1 tbs.
  5. Once the olive oil starts to smoke, add the mushrooms and sear them in batches, making sure not to crowd them!! If you crow them they will steam and won’t sear properly. Cook all mushrooms and set aside on a plate.
  6. Now you are ready to assemble, make sure oven is at 350 degrees. Drizzle 1/2 tbs of truffle oil over the crust.
  7. Next, spread the ricotta in an even layer on top of the oil drizzled crust. Pat it down slightly so the whole crust is covered.
  8. Lay the mushrooms down over the ricotta. Arrange the mushrooms how you like, trying to cover the whole tart.
  9. Drizzle with 1 tbs truffle oil (or more for a richer flavor), sprinkle with fresh thyme and salt.
  10. Bake in the oven for about 25 minutes, until the tart is set and the mushrooms have baked into the ricotta. Remove from oven, cool and cut yo’self a big slice.

The kitchen is my haven and feeding people is my activity of choice. Butter is as crucial to my life as air, and if you put avocado or bacon on anything and put it in my vicinity, consider it gone. Check out my recipes and food adventures on

Soooo watery, maybe the ricotta should be drained? Add an egg?

This was delicious, but really messy / watery. I don't think I properly seared the mushrooms and a lot of liquid released while baking. I may try roasting the mushrooms first if I try this again.
