Ingredients

• 2 large Portabella mushrooms
• 2 tablespoons Olive oil
• 1 tablespoon Unsalted butter
• 1 medium Yellow onion
• 2 cloves Garlic
• 4 large Eggs
• 1.5 cups Heavy cream
• 0.5 cups Milk
• 1 cup Shredded Gruyère cheese
• 0.5 cups Shredded Parmesan cheese
• 1 teaspoon Fresh thyme
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 1 9-inch Prepared pie crust

Directions

Step 1

Preheat the oven to 375°F (190°C).

Step 2

Clean the portabella mushrooms, remove the stems, and slice them into thin strips.

Step 3

In a large skillet, heat the olive oil and butter over medium heat. Add the sliced mushrooms and sauté for 6-8 minutes until softened and slightly browned. Remove the mushrooms and set aside.

Step 4

Peel and finely chop the yellow onion. In the same skillet, sauté the onion for 4-5 minutes until translucent. Mince the garlic and add it to the skillet, cooking for an additional 1 minute. Remove from heat.

Step 5

In a mixing bowl, whisk together the eggs, heavy cream, and milk until well combined.

Step 6

Stir in the shredded Gruyère cheese, Parmesan cheese, thyme, salt, and black pepper.

Step 7

Gently fold in the sautéed mushrooms, onions, and garlic.

Step 8

Roll out the prepared pie crust and place it into a 9-inch pie dish, pressing it into the edges. Trim any excess crust.

Step 9

Pour the quiche filling evenly into the pie crust.

Step 10

Place the quiche on a baking sheet to catch any spills, then bake in the preheated oven for 40-45 minutes, or until the center is set and the top is golden brown.

Step 11

Allow the quiche to cool for 10 minutes before slicing. Serve warm or at room temperature.
