Step 1

Preheat oven to 375 degrees.

Step 2

In a large bowl add flours, salt, pepper, oregano, thyme, butter, and cream cheese. Use handheld mixer or a pastry blender to mix ingredients.

Step 3

Add in egg and mix until you form a dough ball.

Step 4

Place dough in a 9-inch pie dish and press with your fingers until the pie dish is evenly covered with the dough. Grab a fork and add a few air holes to make sure you are not allowing any pockets.

Step 5

Bake in the oven for 8 to 10 minutes, until slightly browned. After the crust is done baking, lower the oven temperature to 350 degrees.

Step 6

While the crust is baking, in a large bowl whisk together eggs and heavy whipping cream.

Step 7

Add in Gruyere, mozzarella cheese, and green onions. Stir to combine.

Step 8

Pour the filling into the crust. Place on the middle rack of the oven to bake evenly at 350 degrees for 40 to 45 minutes. Top with cheddar cheese at the 30-minute mark. If your crust is starting to look dark brown, you might want to cover it at this point as well.

Step 9

Bake until the cheddar cheese fully melts (40-45 minutes total). The center will be just slightly jiggly when done.

Step 10

After removing the quiche from the oven, let it sit for about 5 minutes to continue cooking the center of the quiche.

Step 11

Slice into 8 pieces. Enjoy!
