Step 1

Add flour, salt, and butter to a food processor. Quickly cut it into the flour until the mixture resembles a coarse meal.

Step 2

Add ice water and pulse for about 30 seconds, to form a soft dough. If the dough doesn't stick together when pressed with your fingers, add a bit more ice water.

Step 3

Remove the dough from the food processor and shape it into a thick disk, wrap it in plastic and refrigerate for at least 2 hours or overnight.

Step 4

Bring to cool room temperature before rolling for the quiche.

Step 5

Lightly flour the dough and the counter.

Step 6

Using a rolling pin, roll out gradually, letting it rest for a few minutes before continuing. This will keep the dough from shrinking back during baking.

Step 7

Roll the dough to a thin round approximately 13-14 inches in diameter, lay it loosely into a 9 1/2-inch springform pan with a removable bottom, coming with the dough on the sides midway or a bit higher.

Step 8

Refrigerate for one hour before pre-baking.

Step 9

Preheat oven to 350 degrees F.

Step 10

Place a large, heavy-bottom skillet over medium heat and add the oil. Once the oil is hot add the onions. Cook, stirring often, until tender, about 5-6 minutes.

Step 11

Add garlic season with salt and pepper and continue to cook for 5 more minutes, or until onion starts to caramelize.

Step 12

Add cabbage and cook, stirring often, until cabbage wilts, about 7 minutes. Season with salt, pepper, smoked paprika, and continue to cook for another 5 to 10 minutes until the cabbage is very tender. Remove from heat.

Step 13

In a medium bowl, beat together egg yolks and eggs.

Step 14

Set the springform pan on a baking sheet to allow for easy handling.

Step 15

Using a pastry brush, lightly brush the bottom of the crust with some of the beaten eggs and place in the oven for 5 minutes. This will seal the crust so that it won’t become soggy when it comes into contact with the custard.

Step 16

Add salt, pepper, milk, and cream to the remaining eggs and whisk together until combine.

Step 17

Spread the cabbage, ⅔ of the chopped cooked bacon, and onion mixture into an even layer onto the crust. Sprinkle cheddar cheese, and green onions evenly on top.

Step 18

Slowly pour the egg custard over the filling.

Step 19

Place the quiche, into the prepared baking sheet, and transfer it in the oven. Bake for 30 to 35 minutes, or until set and just beginning to color on top.

Step 20

Remove from oven and allow to sit for at least 10-15 minutes before slicing serving.

Step 21

Garnish with green onions and serve with lemon wedges.
