Onion Tart

This delicious Onion Tart recipe is from the book, "The Bread Bible" by Beth Hensperger. According to the author, this is a relative of quiche, an onion custard baked in yeasted bread dough. The topping is actually just like a quiche's with the base of a yeasted bread. I supposed it is called a tart because it is baked in a tart pan? 

Looks like a quiche, doesn't it?


How this is made :

1. I used the bread machine to do the kneading. If you would like to knead by hand or by using the stand mixer, refer to the instructions in the recipe below. The dough was really wet, I was actually expecting that, and forgotten to reduce the amount of liquid when I mixed the dough. So I added in another 1/4 cup of bread flour during the kneading cycle, and ended up using 3/4 cup more than the recipe calls for, which total to 3-3/4 cups. It was still sticky but decided not to add anymore flour after that. I used the "Quick Dough" cycle in my bread machine, where the machine kneads the dough for 6 minutes, and I have repeated the cycle totalling 3 rounds, that comes to 18 minutes of kneading. I have reduced the salt from 1-1/2 tablespoons to 1-1/2 teaspoons and the yeast from 1 tablespoon to 3/4 tablespoon.
2. Remove dough from bread machine pan, and flour your hands and work surface as the dough is soft and sticky. Shape into a round and place in greased large bowl, turning over once so the top of dough is oiled, cover bowl with greased cling wrap and leave to rise until tripled in size.
3. Punch down dough gently, divide dough into two, freeze one for later use, and roll out the other half of the dough to fit a round tart pan or pizza pan. I have used a 11" pizza pan and only fill the base of the pan, not the sides. And also I have used slightly more than half of the total dough, as I wanted a thicker base.
4. Prepare the onion filling as per instructions in the recipe below. I have added in 2 slices of bacon, chopped to pieces and fry lightly for a couple of minutes, add that to the onions with 1 teaspoon of dried oregano. Scatter the onion and bacon mixture over the rolled dough in the pan.
5. I have made my own creme fraiche for the custard, mixed with some eggs, salt and black pepper. Pour this mixture over the onion filling.
6. Bake in a preheated oven for 35 minutes at 375F.

The onion filling will puffed and turn golden brown when cooked. Just like a quiche.

Only difference is, the base is yeasted bread. And the bread is very soft, fluffy and so delicious with the onion filling. The onions which are fried until caramelized, brown and soft are very sweet and delicious, that is if you like onions.

These are so good eaten warm, about 10 minutes right after baking.

According to the book, this can be eaten hot, warm or at room temperature. I have no idea if these are as good at room temperature. We finished everything in less than 20 minutes, while it was still warm and delicious! This bread tart do reminds me of focaccia.

Two days later, I took the other frozen dough out from the freezer and was surprised that it was not completely frozen, maybe because I store it at the compartment of the freezer door and not cold enough? Left it on the kitchen counter for half an hour, pat it into a 8" tart pan, top with some cheese, and use some leftover spaghetti sauce as the topping, and scatter more cheese over. Bake for 35 minutes at 375F.

It was yummy! The bread is so soft! You can see how fluffy the bread is from the photo above. This is like eating pizza! Made this for the kids' after school lunch! It is definitely a winner! I'll be making the dough again to store in the freezer, simply a breeze for a quick meal. A definite keeper recipe, I can see lots of future baking from this book. 

Onion Tart

Tart Dough (enough for two 12" tarts or 1 shallow 11-by-17-inch sheet)
1 tablespoon (1 package active dry yeast) (I use 3/4 tbsp)
1 tablespoon sugar
1 cup warm water (105 to 115F)
2-3/4 to 3 cups unbleached all-purpose flour or bread flour (I used in total 3-3/4 cups bread flour)
1-1/2 tablespoons salt (I use 1-1/2 teaspoon salt)
2 tablespoons corn oil
1 large egg, at room temperature, slightly beaten

Onion Filling
4 large onions, thinly sliced
8 tablespoons (1 stick) unsalted butter (I use 2 tbsp canola oil)
1 cup sour cream or creme fraiche (I use 3/4 cup homemade creme fraiche)
3 large eggs, at room temperature
pinch of salt
1 teaspoon freshly ground black pepper
2 slices bacon (my addition)
1 tsp dried oregano (my addition)

1. To make the tart dough : Put the yeast, a pinch of the sugar, and 1/2 cup warm water in a small bowl. Stir until dissolved and let stand at room temperature until foamy, about 10 minutes.
2. In a large bowl using a whisk or in the work bowl of a heavy-duty electric mixer fitted with the paddle attachment, combine 1 cup flour, 1 tablespoon sugar, and the salt. Add the remaining water, oil, egg, and yeast mixture. Beat hard until smooth, about 3 minutes. Add the flour, 1/2 cup at a time, and beat with a wooden spoon until a shaggy dough that just clears the sides of the bowl is formed.
3. Turn the dough out onto a lightly floured work surface and knead until smooth, resilient, and no longer sticky, about 5 minutes, dusitng with flour only 1 tablespoon at a time as needed to prevent sticking. Shape into a ball. (If kneading by machine, switch from the paddle to the dough hook and knead for 3 to 4 minutes, or until the dough is smooth and springy and springs back when pressed. If desired, transfer the dough to a floured surface and knead briefly by hand.
4. Place the dough in a greased bowl. Turn once to grease the top and cover with plastic wrap. Let rise at room temperature until tripled in bulk, 1 to 1-1/2 hours.
5. To make the onion filling : In a skillet saute pan over low heat, cook the sliced onions in butter until golden and soft, about 20 minutes. Let cool to room temperature. Just before shaping dough, combine sour cream, eggs, salt, and pepper in a bowl ; add onions.
6. Gently deflate the dough. Turn out the dough onto a lightly floured work surface. Grease a springform pan or tart tin with a removable bottom. Divide dough into 2 equal portions; freeze 1 for later use. Roll out the remaining portion to fit the pan or tart in. Pat into the bottom and up the sides. Fold any extra dough down. Pour the onion mixture over the dough.
7. Twenty minutes before baking, preheat the oven to 375F. Place the pan or tin on a rack in the center of the oven and bake for 35 minutes, or until crispy and golden. The onion filling will be delicate brown and puffy. Let stand 10 minutes before removing the sides of the pan to cool before cutting into wedges.
