Step 1

Preheat oven to 350 degrees F and grease a quiche, pie, or casserole dish.

Step 2

Add a pinch of salt to the grated zucchini and let sit for a few minutes. Then, squeeze as much water out of it as possible by wringing it in a clean kitchen towel or paper towel.

Step 3

In a large bowl, whisk together the 4 eggs, milk (2 cups), flour (3/4 cup), and baking powder (1 teaspoon) until well combined.

Step 4

Stir in the remaining ingredients, including a little bit of salt and pepper (but not too much, since the ham and cheese are already salty).

Step 5

Pour batter into prepared baking dish and use a spatula or wooden spoon to distribute the batter evenly in the pan.

Step 6

Place the quiche on top of a foil-lined baking sheet, in case it spills over (it will be very full) and to make it easier to remove from the oven.

Step 7

Bake at 350 degrees F for 45 minutes, or until the top is golden brown and quiche is fully cooked through (if you shake it a little, it shouldn't jiggle).

Step 8

Allow to cool for at least 10 minutes before cutting into it. Can be served warm or at room temperature.
