Common around Germany and the Alsace wherever wine is grown, this Onion Pie is a very welcome addition to any winter dinner. Enjoy warm, fresh from the oven, or days later with a glass of wine.
Dissolve the yeast in the lukewarm milk with the sugar and a dash of the flour.
Stir, cover, and keep in a warm place for 10 minutes.
Add the rest of the dough ingredients, mix (by hand or stand mixer) until a ball forms.
Cover and keep in a warm place until the dough rises.
In the meantime preheat the oven to 425°F and sautee the onions with the bacon in a large skillet until translucent but not brown.
While sauteeing the onions mix the Eggs, Creme Fraîche, freshly grated Nutmeg, and pepper together with a whisk until smooth and well combined.
Roll the dough out and place into a roasting pan. Give it about a 1 inch "lip".
Add the onion and bacon mixture on top of the dough.
Pour the Creme Fraîche mixture over the onions and smooth out.
Bake for 30 to 40 minutes until dough is firm and top is golden brown.
