For the Dough
- 2 1/2 cups All-purpose flour
- 2 tbsp Vegetable oil
- 3/4 cup Warm water
- 1 tsp Active dry yeast
- 1 tsp Sugar
- 1 tsp Salt
For the Filling
- 6 large Yellow onions
- 6 oz Thick-cut bacon
For the Custard
- 1/2 cup Sour cream
- 1/2 cup Heavy cream
- 2 large Eggs
- 1 tsp Caraway seeds
- 1 tbsp Fresh thyme
- Salt and pepper, to taste
Optional Toppings
- Crème fraîche
- Fresh chives
- Nutmeg, a pinch
- Activate Yeast: Dissolve 1 tsp of active dry yeast and 1 tsp of sugar in 3/4 cup of warm water. Let the mixture sit for 5 minutes until it becomes frothy, indicating the yeast is active.
- Mix Dough: In a large bowl, combine 2 1/2 cups all-purpose flour with 1 tsp salt. Add the yeast mixture and 2 tbsp vegetable oil, stirring to form a sticky dough.
- Knead Dough: Turn the dough onto a floured surface and knead vigorously for about 10 minutes until smooth and elastic. Place it in a lightly oiled bowl, cover with a clean towel, and let it rise in a warm place for 1 hour until doubled in size.
- Cook Bacon: While the dough is rising, cook 6 oz thick-cut bacon in a skillet over medium heat until crispy. Remove the bacon and set aside, reserving the rendered fat in the skillet.
- Caramelize Onions: Peel and thinly slice 6 large yellow onions. Add them to the bacon fat in the skillet and cook over low heat for about 45 minutes, stirring occasionally, until the onions are golden and caramelized.
- Prepare Custard: In a mixing bowl, whisk together 1/2 cup sour cream, 1/2 cup heavy cream, 2 large eggs, 1 tsp caraway seeds, 1 tbsp fresh thyme leaves, a pinch of nutmeg (optional), and salt and pepper to taste.
- Assemble Pie: Preheat oven to 375°F (190°C). Roll out the risen dough on a floured surface to fit a 9-inch tart or pie pan. Transfer the dough to the pan, pressing it firmly to the edges.
- Layer Filling: Spread the caramelized onions evenly over the dough, sprinkle the crispy bacon pieces on top, then pour the custard mixture over all.
- Bake: Bake the pie in the preheated oven for 35-40 minutes, or until the custard is set and the top is lightly golden.
- Serve: Allow the pie to cool slightly before serving. Optionally, top with a dollop of crème fraîche and sprinkle with freshly chopped chives for extra flavor.
Notes
- Use yellow onions for their natural sweetness which caramelizes best.
- Make sure to cook the onions slowly on low heat to develop rich flavor without burning.
- You can substitute bacon with smoked pancetta for a different smoky taste.
- Dough can be prepared a day ahead and refrigerated for convenience.
- To make it vegetarian, omit bacon and increase caraway seeds and thyme for more flavor.
