Ingredients
  

German Onion Pie Ingredients
  • 1.5 cups all-purpose flour (180g) for the pastry crust
  • 0.5 cup unsalted butter (115g) ice-cold and cubed
  • 4 tbsp ice water (60ml) or as needed
  • 0.5 tsp salt (3g) for the dough
  • 8 oz smoky slab bacon (225g) diced
  • 2 lbs yellow sweet onions (900g) thinly sliced
  • 1 cup heavy cream (240ml)
  • 3 large eggs whole
  • 1 pinch nutmeg freshly grated
  • 1 tsp caraway seeds (3g) whole, tiny brown seeds
  • 2 tbsp fresh chives (10g) finely chopped

Equipment

  • 1 9-inch round ceramic tart pan with fluted edges Essential for even heat distribution and a beautiful presentation.
  • 1 Heavy-bottomed Skillet or Dutch Oven Crucial for properly caramelizing the onions without burning.

Method
 

Making the German Onion Pie
  1. Pulse the flour, salt, and ice-cold cubed butter in a food processor until it resembles coarse crumbs. Drizzle in ice water until the dough comes together. Form a disc, wrap tightly, and chill for 30 minutes.
  2. Roll the dough into your round ceramic tart pan, pressing into the fluted edges. Blind bake with pie weights at 375°F (190°C) for 15 minutes.
  3. In a heavy skillet, render the diced bacon until crispy and dark red-brown. Remove the bacon but leave 2 tbsp (30ml) of fat in the pan.
  4. Cook the sliced onions in the hot bacon fat over medium-low heat for 25-30 minutes until translucent. Raise the heat at the very end to achieve lightly charred edges.
  5. Whisk together the heavy cream, eggs, salt, pepper, and nutmeg until well incorporated and airy.
  6. Fold the caramelized onions and half the bacon into the custard. Pour into the blind-baked crust. Sprinkle remaining bacon and caraway seeds on top.
  7. Bake at 375°F (190°C) for 35-40 minutes until the custard is slightly puffed, golden-blistered, and set. Cool for 15 minutes, then garnish with finely chopped green chives.

Notes

Tip 1: Ensure your butter and water are ice-cold for the flakiest crust.
Tip 2: Do not skip the 15-minute resting period after baking; it allows the rich custard to perfectly set before slicing.
