Ingredients

Instructions

  1. Step 1: For crust: Pulse 1 1/4 cups all-purpose flour and 1/2 tsp salt in a food processor. Add 1/2 cup cubed cold unsalted butter and pulse until pea-sized crumbs form. Drizzle in 3 tbsp ice water and pulse until dough holds together. Press into a 9-inch tart pan, chill 30 minutes.
  2. Step 2: Preheat oven to 375°F. Blind-bake crust for 15 minutes with parchment and pie weights. Remove weights, bake 5 more minutes until golden; set aside.
  3. Step 3: Sauté 2 cups sliced mushrooms and 1/2 diced shallot in a skillet over medium heat with 1 tsp butter until golden (8-10 minutes). Stir in 1 tbsp chopped thyme, 2 tbsp chopped parsley, 1 tsp lemon zest, 1/2 tsp salt, and 1/4 tsp black pepper; cook 2 minutes.
  4. Step 4: Whisk together 1/4 cup heavy cream, 1/4 cup grated Parmesan, 1/2 tsp salt, and 1/4 tsp black pepper. Spread mushroom mixture evenly in the baked crust, then pour cream mixture over it.
  5. Step 5: Bake at 375°F for 25-30 minutes until filling is set and edges are golden. Cool 15 minutes before slicing.
