My Tip - 3 things. 1. Make sure you don't over boil your cauliflower. No longer than 8 to 10 minutes. Tops! 2. Make sure you dry the cauliflower as much as possible after boiling it. Try patting it down well with a paper towel... if you don't, the cauliflower will make the quiche soggy. 3. Make sure you allow 20 minutes to cool before serving. This gives the quiche some time to firm up a bit and makes slicing it easier.
Crustless Cauliflower & Ham Quiche
1/2 head cauliflower, cut into bite-size florets
2 tablespoons extra-virg in olive oil
1 cup chopped white onion, about 1 medium
2 tablespoons chopped flat-leaf parsley
4 ounces deli boiled ham, cut in 1/4-inch cubes
2 tablespoons unsalted butter, softened
2 tablespoons finely grated Parmesan cheese
2 cups half-and-half
2 large eggs
2 large egg yolks
1 tablespoon all-purpose flour
1/2 teaspoon kosher salt
Freshly ground black pepper
4 ounces grated Gruyere or Swiss cheese, about 1 cup
1. Preheat oven to 350 degrees F.
2. Bring a large pot of salted water to a boil. Add cauliflower florets and cook until very crisp tender, about 1 minute. Drain in colander and rinse with cold water. Shake off excess liquid.
3. Heat the oil in a large skillet, over medium-high heat. Add the ham and the onions and cook until lightly brown, about 6 minutes. Add cauliflower and parsley and set aside to cool slightly.
4. Brush a 9-inch glass or ceramic pie pan with the soft butter and evenly sprinkle the bottom of the pan with the grated Parmesan cheese. Place pan on a baking sheet. Whisk the half-and-half, eggs, egg yolks and flour in large glass measuring cup. Season with salt and pepper, to taste. Spread half the cauliflower mixture evenly in the pan, top with about half the cheese; repeat with remaining filling and cheese. Pour the custard over the fillings.
5. Bake until the quiche is just set in the center, about 40 to 50 minutes. Cool on a rack before serving.
