Description

Traditional German Onion Pie featuring a homemade yeast crust filled with slowly cooked onions, bacon, and a creamy egg custard. This savory pie is perfect for dinner, brunch, or entertaining.


Ingredients

For the Yeast Dough:

  • 250 g (2 cups) all-purpose flour
  • 55 g (4 tablespoons) butter, softened
  • 3 g (1 teaspoon) active-dry yeast
  • 1 teaspoon salt
  • 1 teaspoon granulated sugar
  • 155 ml (⅔ cup) lukewarm milk

For the Onion Filling:

  • 500 g (about 4 medium) yellow onions
  • 55 g (4 tablespoons) butter for cooking onions
  • 1 tablespoon all-purpose flour
  • 2 large eggs
  • 100 ml (scant ½ cup) heavy cream
  • 2 slices thick-cut bacon, diced into small strips
  • 1 teaspoon caraway seeds (optional but traditional)
  • Salt to taste
  • Extra butter for greasing the pan

Substitution Notes:

  • Skip caraway seeds if you don’t have them
  • Leave out bacon for vegetarian version
  • Plant milk works fine instead of regular milk


Instructions

Create the Yeast Dough

Mix yeast and sugar with some of the milk. Wait until it bubbles – about 5 minutes. Add everything else and knead until smooth. Cover and let it double somewhere warm. Takes over an hour.

Cook the Onions

Slice onions however you want. Cook in butter on medium heat until soft, not brown. Takes 15 minutes of stirring. Mix in flour and salt. Let cool.

Mix the Custard

Beat eggs and cream. Add caraway if you have it. Done.

Put It Together

Grease your pan. Press dough in, making sides about an inch high. Add onions, pour egg stuff over, sprinkle bacon around.

Bake Until Golden

Oven at 390°F for 35-45 minutes. Middle shouldn’t wiggle when you shake the pan gently.

Cool and Serve

Wait 10 minutes or it falls apart when you cut it.

Notes

Don’t rush the onions or they’ll brown instead of getting sweet. Spread bacon around so it’s not all in one spot.

That flour mixed with onions stops watery disasters. If your yeast doesn’t bubble after 10 minutes, it’s dead and you need new yeast.

The crust should be bread-like, not flaky like regular pie crust. If you’re used to making regular pies, this will feel weird at first. Trust the process – the bread texture is what makes this special and prevents soggy bottom syndrome.
