Gluten Free Mushroom Quiche

The gluten free pate brisee dough offers a flaky base. It has the same quality as the traditional shortcrust pastry dough. This irresistible vegetarian quiche is an excellent option for those looking to enjoy a gourmet meal without gluten or dairy.

Key Ingredients And Substitutes

  • Gluten free flour blend – used for the crust, Schar, or Caputo gluten free flour provides a good structure without gluten. 
  • Vegan Butter – used for the pie crust, Violife Salted Vegan Butter and Flora+ Vegan Butter are the best choices. 
  • Mushrooms – portobello or white mushrooms are ideal. Do a combination of mushrooms you prefer for different flavors.
  • Onions – yellow onions are best for caramelizing. Otherwise, use red onions for a stronger taste.
  • Eggs – are essential for the quiche filling to set. Just Egg is the substitute for the vegan option.
  • Dairy free Cooking Cream – oat cooking cream goes well with onions and mushrooms. Soy-based cooking cream works, too.

How To make the filling of gluten free mushroom quiche

  • Clean mushrooms with a damp cloth and slice them. Sauté with olive oil in a separate pan over medium-high heat until no moisture and golden brown. Season with salt and pepper to taste, then set aside.
  • Slice onions thinly and cook over low heat with olive oil while stirring occasionally until golden brown. It takes about 20-30 minutes. Set aside.
  • For the quiche egg mixture, combine all ingredients, then beat to loosen the eggs and cream.

Handling and Baking of gluten free Shortcrust dough

  • Chill the shaped dough in the pie dish or tart ring for at least 30 minutes before baking to help retain its shape.
  • Use pie weights or dried beans on parchment paper over the dough during blind baking to keep the crust bottom flat.
  • Pre-baking at 190°C (375°F) for 18-20 minutes.
  • Cool the crust completely before filling to prevent it from breaking and becoming soggy.

Step By Step Instructions

STEP 1
  • Cream the cold butter cubes, salt, sugar, and eggs on a cold work surface with your finger until the dough becomes crumbs.
  • Add the cold water, then mix until the dough clumps together. Wrap it with cling film, then refrigerate for an hour.
  • Check out the Gluten Free Pate Sucree recipe for complete details.
STEP 2
  • Sauté the onions until caramelized. Using the same pan, sauté the mushrooms and cook them until golden and all liquid has evaporated. Let cool.
  • Whisk together eggs, dairy free cooking cream, salt, nutmeg, and pepper in a bowl. Spread the mushroom and onion mixture evenly over the pre-baked crust. Pour the egg mixture on top.
STEP 3
  • For a large, thick quiche (20 x 5 cm or 8 x 2 in), bake at 145°C (293°F) for 25 minutes, then adjust the temperature to 170°C (338°F) and continue baking for another 15 minutes.
  • For thinner quiche, bake at 170°C (338°F) for 35 to 40 minutes.
  • Let the quiche cool for 15-30 minutes before slicing and serving.

Equipment

Ingredients
 
 

Gluten Free Pate Brisee

Quiche Filling

  • 500 g white mushrooms
  • 4 pcs yellow or white onions large
  • 250 g eggs about 5 large eggs
  • 250 g vegan cooking cream, soy-free, nut-free Califia Heavy cream is preferred
  • 4 g salt
  • 1 g nutmeg powder
  • 1 g black pepper powder

Instructions
 

Gluten Free Pate Brisee or Shortcrust Dough

  • Cream the cold butter cubes, salt, sugar, and eggs on a cold surface using your fingers until the mixture resembles crumbs.
  • Incorporate the cold water and continue mixing until the dough forms a ball. Wrap the dough with cling film and refrigerate for one hour.
  • For a detailed guide, refer to the Gluten Free Pate Sucree recipe.

Quiche Filling and Baking

  • Caramelize the onions by sautéing them until golden brown. In the same pan, sauté the mushrooms until golden and all liquid evaporates. Season with salt and pepper. Set aside.
  • Combine eggs, dairy free cooking cream, salt, nutmeg, and pepper in a bowl, whisking thoroughly. Spread the sauteed mushroom and onion evenly over the pre-baked crust, then pour the egg mixture on top.
  • For a large, thick quiche (20 x 5 cm or 8 x 2 in), bake at 145°C (293°F) for 25 minutes, then adjust the temperature to 170°C (338°F) and continue baking for another 15 minutes.
  • For thinner quiche, bake at 170°C (338°F) for 35 to 40 minutes.
  • Let the quiche cool for 15-30 minutes before slicing.

Notes

  • Keep all ingredients as cold as possible during dough-making for a flakier crust.
  • Blind bake the crust for 20 minutes before adding the filling to prevent sogginess.
  • Do not overcook the quiche. The filling should still jiggle a bit when you shake it. 
  • Try adding different herbs, such as thyme or rosemary, to the mushroom and onion mixture for added flavor.
  • Allow the quiche to rest for at least 20 minutes before cutting to ensure the filling sets properly.
