1 medium cauliflower (1 1/2 pounds, 23 to 24 ounces or 650 to 700 grams)
1 large red or white onion, peeled
5 to 7 1/2 tablespoons (100 grams or 3.5 ounces) olive oil
1/2 teaspoon finely chopped rosemary
10 medium or 8 large eggs
Handful (3/4 ounce or 20 grams) basil, chiffonaded
Scant 1 1/2 cups (180 grams or 6.3 ounces) all-purpose flour
2 1/2 teaspoons baking powder
1/2 teaspoon ground curcumin
2 cups finely grated parmesan cheese (200 grams or 7 3/4 ounces) or about 1 generous cup of grated Romano cheese
Salt and white pepper
Butter, for greasing pan
Preheat oven to 350°F (180°C) degrees. Break cauliflower into medium florets (this will cause less mess than chopping it). Place floret in a pot with a teaspoon of salt, cover them with water and simmer for 15 to 20 minutes, until quite soft. Strain and let drip in the colander for a few minutes so they dry and cool.
Meanwhile, prepare the batter. Halve your red onion and cut a few thin rings off the end of one side; set them aside. Coarsely chop the remainder of your onion. Heat all of your olive oil in a saucepan (consider reusing the one you cooked your cauliflower in) and sautee the chopped red onion and rosemary together until soft, about 8 minutes. Remove from heat and allow to cool.
Whisk eggs and olive oil and onion mixture together. Stir in basil. Whisk flour, baking powder, curcumin, cheese, 1 1/2 teaspoons salt (use 1 teaspoon if you are nervous about this amount) and several dashes of white pepper in a separate bowl and add to egg mixture, whisking to remove lumps. Stir in cauliflower gently, so most pieces remain intact.
Line the bottom of a 9-inch (24cm) round springform pan with parchment paper. Butter the sides generously. Pour in the cauliflower batter, arrange the reserved onion rings on top and bake cake in the center of the oven for 45 minutes, until golden brown and set.
Serve warm or at room temperature. Before you serve the cake, be sure to run a knife around the pan.
Some of you may be wondering…why is there so much flour in a low oxalate recipe? Trust me; this cauliflower “cake” is so dense, one serving is pretty filling. Just be sure to serve it with some low oxalate sides, such as a nice salad made with Romaine lettuce and red peppers, or perhaps some peaches or cherries. I do wonder how you could make it with coconut flour…perhaps using a lot of flaxseed and reducing the amount of flour to ½ cup? I might experiment with it. Rice flour also sounds like a promising experiment.
To clarify, it is a savory dish. Unlike a quiche, the flour is folded directly into the egg mixture. The result is a pretty, tasty dish (though it did stick a bit to the pan). I would recommend using the springform pan. If you don’t have one, be sure to really grease your baking pan; it is a bit sticky. I got many, many servings out of this. It reheats well and makes for an ideal Sunday supper.
