Spinach Quiche Pie Casserole Souffle

I don't know what to call it. I want to say Spinach Quiche but I think of "round" when I think quiche (and pie) and this was baked in a 9x13 casserole dish. At our house we don't like the word casserole and I looked up the definition of souffle and this dish doesn't quite fit the part. So, I'm going to call it crustless spinach quiche since you could bake it in two round dishes

I found this recipe for Spinach & Chicken Pie in the March 09 Family Circle magazine. I based my recipe on this but it is far from the same. I ate some delicious quiche at Café Niche a while back and have been trying to pinpoint their spices ever since. The following recipe seemed to taste almost as good.

Crustless Spinach Quiche
Ingredients
2 tablespoons butter or margarine
1 large yellow onion, chopped
1 can (15oz) white cannellini beans, drained & rinsed
About 3 cups fresh chopped spinach*
1 1/2 teaspoons salt (or less)
1 teaspoon black pepper
1/2 teaspoon ground nutmeg
1/4 teaspoon red pepper flakes
3 heaping tablespoonfuls cottage cheese
6 eggs, lightly beaten (I used medium eggs)
4 tablespoons flour (I used rice flour)
1 tablespoon fresh oregano, chopped

Directions
1. Heat oven to 375 degrees F.

2. Coat 13x9x2-inch baking pan with nonstick cooking spray.

3. Chop onions, put in casserole dish with butter, cook in microwave for 2 minutes, stirring after 1 minute. (I did this because I was lazy and didn't want to use another pan. You can saute the onions & butter in a skillet on the stove if you want to.)

4. Chop fresh spinach. (I chopped 2 batches in my food processor, on pulse.) Add spinach, beans, cottage cheese to the casserole dish.

5. Mix together eggs, flour, salt, pepper, nutmeg, red pepper flakes, fresh oregano. Pour over casserole dish and stir together to mix.

6. Bake at 375 degrees for 45 minutes, until top is browned.

* I get the big bag of fresh spinach from Costco. This is a good way to use some of it up. If you don't have fresh, you can use 3 (10 ounce) packages frozen chopped spinach, thawed and squeezed dry.
