Breakfast Pizzas

Ingredients

• 12 slices bacon thick-cut crisp cooked
• 0.5  day-old brioche 
• 1 cup caramelized onions 
• 0.5 cup crème fraîche 
• 8 large eggs 
• 2 cups part-skim mozzarella cheese shredded

Equipment

• baking sheet
• baking paper
• oven
• knife

Directions

1. Preheat the oven to 350°F/180°C, and place one rack in the center and one rack in the top third of the oven. Line the baking sheets with parchment paper.
2. Shape the brioche dough into a rectangle about 8 in/20 cm long, 4 in/10 cm wide, and 1 in/2.5 cm thick. Using a ruler and a knife, cut the rectangle into eight 2-in/5-cm squares by first dividing it in half horizontally and then dividing it vertically into strips 2 in/5 cm wide. Each square of dough should weigh about 3 1/2 oz/100 g. Stretch each square into a circle about 5 in/12 cm in diameter as if you are making a small pizza. Stretch the inner part of the circle so that it is quite thin and shape the edge of the circle to create a rim. The center should be almost paper-thin, and the finished circle should look like you are making the crust for a mini deep-dish pizza.
3. Place the brioche circle on one of the prepared baking sheets and repeat with the remaining dough squares, spacing them 2 to 3 in/5 to 7.5 cm apart and using both baking sheets.
4. Using the back of a spoon, spread 1 tbsp of the crème fraîche over the base of each brioche circle, spreading it evenly over the base but leaving the rim bare.
5. Cut the bacon slices in half. For each pizza, press three half slices of bacon against the brioche rim to create a bacon wall. Divide the caramelized onions evenly among the pizzas, spooning and spreading the onions next to the bacon and leaving the center of the circle bare except for the crème fraîche.
6. Bake the pizzas, switching the baking sheets between the racks and rotating them back to front about halfway during baking, for about 15 minutes, or until the edges of the pizza start to turn light brown.
7. Remove the baking sheets from the oven and carefully crack an egg into the center of each pizza.
8. Sprinkle about 1/4 cup/30 g of the mozzarella on top of each pizza, covering both the egg and the exposed rim of brioche.
9. Bake for another 8 to 10 minutes, again switching the baking sheets between racks and rotating them back to front about halfway during baking, or until the cheese has melted, the edges of the egg are cooked but the yolk is still wiggly, and the edges of the pizza are golden brown.
10. Remove from the oven.
11. Let the pizzas cool for 8 to 10 minutes to allow the eggs to set up a bit before serving.
12. Ham, Ricotta, and Parmesan Variation: Omit the bacon, onions, and mozzarella. Substitute 4 ounces/115 grams sliced ham, 1 cup/250 grams fresh whole-milk ricotta cheese, and 1 cup/100 grams freshly grated Parmesan cheese. Using about 1/2 ounce/15 grams ham per pizza, tear the ham into small pieces and press the pieces against the brioche rim to create a ham wall.
13. Spread 2 tablespoons of the ricotta along the edges of each pizza next to the ham, leaving the center of the brioche circle bare except for the crème fraîche .
14. Bake as directed, substituting 2 tablespoons of the grated Parmesan in place of the mozzarella sprinkled over the egg on each pizza.
15. Let cool for 8 to 10 minutes before serving.Tomato and Cheddar: Omit the bacon, onions, and mozzarella. Substitute 2 ripe tomatoes, thinly sliced, and 8 ounces/225 grams Cheddar cheese, thinly sliced. Using 2 to 3 tomato slices per pizza, tear the slices into pieces and press the pieces against the edge of the brioche rim to create a tomato wall, leaving the center of the brioche circle bare except for the crème fraîche.
16. Bake as directed, substituting 1 ounce/30 grams of the sliced Cheddar in place of the mozzarella sprinkled over the egg on each pizza.
17. Let cool for 8 to 10 minutes before serving.
