Onion and Rosemary Tart

I served this dish at a potluck where it received rave reviews. I think its success is due in part to the use of sweet onions. This dish is quite easy, except for the hassle of making the pastry. I skipped a few steps and it turned out great. I'll tell you how I did it, and how it was supposed to be done.

I'm not exactly clear what makes something a tart rather than a quiche, but I think it may be the use of a tart pan which is shallow and has scalloped edges, such as the one shown in the picture. My tart pan has a removable bottom, so you can remove the sides of the pan and serve the tart with just the crust showing, which is much prettier than including the pan in your presentation.

To make a tart shell according to the recipe you have to make the dough, let it chill in the refrigerator for 15-30 minutes, roll it out and put it in the tart pan, freeze it for half an hour or more, pre-bake it, take it out of the oven and fill it with your filling, and then bake. If you started early in the day or made your shell ahead of time, that would be fine. I didn't have time for all that so I let it chill for about 5 minutes, didn't bother freezing it, and pre-baked it while preparing the filling. It turned out great and saved some time. You could also use a store-bought pie crust and save a lot of time, but increase your cost for the dish. The homemade crust uses half all-purpose flour, and half whole-wheat pastry flour, which makes it better for you than a store-bought crust. Even if you use store-bought, I think you would still need to pre-bake it so that it doesn't get soggy when you add the wet ingredients.

It may sound a little strange to make a quiche-like filling out of just onions and rosemary, but it is absolutely delicious and very simple.

To get started

• Prepare the tart shell: In a food processor, combine 1/2 cup all purpose flour, 1/2 cup whole wheat pastry flour, and 3/4 t. salt. Pulse just to combine. Add 5 T. cold butter, cut into small pieces. Pulse until the mixture resembles course meal. Add 3 T. sour cream. Pulse again. Add 1 T. ice water and pulse again. The mixture should be moist and crumbly. Turn the mixture out onto a board, gather it into a ball, then flatten it into a disk. Refrigerate for 15 minutes.

• While the dough is chilling, melt 2 teaspoons butter in a dutch oven or large skillet over medium heat. Quarter 4 small or 3 medium onions, and then slice them thinly crosswise. Add the onions to the butter, add a pinch of salt, stir and cover. Cook the onions until soft and pale golden, about half an hour, stirring occasionally.

• Mince 2 teaspoons fresh rosemary and set aside.
• Preheat the oven to 425º

• Flour a work surface. Roll out the dough into a 10 inch circle. Drape it over your rolling pin and settle it into the tart pan. (No need to grease the pan.) Using your fingers, shape the dough on the sides of the pan and try to make it uniformly about 1/4 inch thick. Remove any excess dough. Bake at 425 for about 20 minutes. When you take the pre-baked shell out of the oven, lower the heat to 350º.
• When the onions are soft, add the rosemary and several grinds of fresh pepper. Taste the onions, and add salt as needed. I also raised the heat a little and cooked the onions for an extra 5 or 10 minutes to cook off some of the liquid.
• In a medium bowl, whisk together 2 eggs and 1 cup fromage blanc. (This is a non-fat french cheese. It was ridiculously expensive at my store, so I used creme fraiche instead which was absolutely delicious.) Add a little salt and pepper.
• Pour the onions into the egg-cheese mixture. Combine and put in the prepared tart shell.
• Bake at 350º for 30 minutes.

I had some leftover onion filling mixture, so I put it in buttered ramekins and baked it along with the tart.
