Instructions

Yeast dough:

  1. Mix flour, instant yeast, salt, and sugar in the stand mixer bowl or another large bowl. Make a well in the middle and add the soft butter and the lukewarm water. If using active dry yeast, dissolve it in the lukewarm water and let it stand for 5 minutes.3 ¾ cups all-purpose flour / 450 g + 2 teaspoons instant yeast + 1 teaspoon granulated sugar + 1 teaspoon fine sea salt + 3 ½ tablespoons butter/ 50 g + 1 cup lukewarm water / 220 ml
  2. Knead the dough for about 5 minutes until it is elastic and pulls away from the sides of the bowl.
  3. Let dough rise: Remove the dough from the bowl and briefly knead it on the work surface, then shape it into a ball. Place the ball back in the bowl, cover it loosely with plastic wrap, and let it rise in a warm place for about 30 minutes or until it doubles in size. The rising time depends on the quality of the yeast and the temperature in your kitchen.
  4. In the meantime, prepare the onion filling and preheat the oven to 400°F/ 200°C. Line the baking sheet with parchment paper.

Onion filling:

  1. Prepare the ingredients: Peel and halve the onions. Cut the halves into fine slices. Finely dice the bacon.2 lbs yellow onions / 900 g + 7 oz thick-cut bacon/ 200 g
  2. Cook: Heat the oil and the butter in a large pan. Add bacon and onions and cook them gently for about 10-15 minutes or until the onions are lightly golden brown. Season generously with salt and pepper and set aside to cool slightly while you roll the dough and mix the remaining filling ingredients.1 tablespoon vegetable oil + 1 tablespoon butter
  3. Combine the eggs, heavy cream, flour, nutmeg, salt, and pepper in a small bowl. Add them to the cooled onion mixture and stir to combine.3 large eggs + ¾ cup heavy cream / 180 ml + 1 ½ tablespoons all-purpose flour + a few gratings of nutmeg + 1 teaspoon fine sea salt + ¼ teaspoon freshly ground black pepper

Assemble the onion cake:

  1. Roll out the yeast dough on a lightly floured surface until it's about the size of your baking sheet. Carefully transfer it to the lined baking sheet and press the edges to form a small rim all around.
  2. Add filling: Pour the onion filling onto the dough and spread it evenly with a spoon or spatula. Sprinkle the grated cheese evenly on top.9 oz cheese / 250 g
  3. Bake the onion cake on the middle shelf for about 30 minutes until the filling is set and the top lightly golden brown. Let rest for 10-15 minutes before slicing and serving. Serve it hot, warm, or at room temperature.

Notes

  • You can halve the recipe and bake it in a 9-10 inch/ 24-26 cm springform pan.
  • Measurements: I strongly recommend measuring the ingredients using a digital kitchen scale (the Amazon affiliate link opens in a new tab); it guarantees the best results.
  • Yeast: You can also use active dry yeast. In this case, mix it with the lukewarm water and let it stand for 5 minutes. You can also use 0.75 oz/ 21 g of fresh yeast. In this case, crumble it into a small bowl, mix it with the sugar and a few tablespoons of the already measured lukewarm water, and let it stand for a few minutes before adding it to the rest of the ingredients.
  • Caraway seeds: If you like, add 1 teaspoon of caraway seeds. I forgot to buy them this time, but I usually add them; I love their flavor.
  • Cheese: I usually use Gouda, which is very common in Germany, but you can also use cheddar or another good-melting cheese you like.
