Coarsly dice the bacon slices. Set aside.
Peel and finely slice the onions.
Preheat a large heavy skillet and saute the bacon until crisp.
Gradually, add all of the sliced onions. Stir well. Cook covered until the onions are translucent and soft but not brown. When finished, let them cool down slightly.
To a medium bowl, add the eggs, sour cream, mustard, flour, caraway seeds, salt, and some fresh ground pepper. Mix well until combined.
Add the onions to this egg-sour cream mixture.
Press the crust or pizza dough into a lightly greased, rectangular baking dish.
Preheat the oven to 375˚F.
Pour the onion mixture over the crust and spread out evenly.
Bake at 375˚F for 40-55 mins or until set and golden-brown.
Serve warm.
These are the traditional ingredients:
onions: I recommend regular white onions, not sweet onions. As they are the main ingredient here, make sure to buy high-quality onions
eggs: these will help the pie to set. I always recommend you use the best ingredients you can afford. Therefore, we love using organic pasture-raised eggs
bacon: bacon adds a bit of a bite and a nice saltiness to the onion pie. We love bacon from pasture-raised pigs but any bacon will work here
sour cream: the addition of sour cream counters the sweetness of the onions and gives it a more complex taste
Dijon mustard: while not being entirely traditional, I love adding a teaspoon of Dijon mustard. It adds just enough of a kick to this dish that I really miss in recipes that don’t use mustard
caraway seeds: I really like to add them since they help you digest the onions. Most people don’t even notice them all that much
AP flour: I like to add some flour to sop up any onion juices
salt & pepper: I don’t think I need to say anything here
a crust: depending on the type of dish you are using, you can use a pastry crust or yeast dough. Either one would be fine. I actually like to use a sourdough pizza crust and will link it here once I am happy with my recipe.
Simple pizza crust
You may have your favorite pie crust or pizza dough recipe but if you don’t here’s a very simple one:
1 tsp active dry yeast
1 cup warm water (110 degrees F/45 degrees C)
2 ½ cups bread flour
2 tablespoons olive oil
1 teaspoon salt
Mix all the ingredients together and knead for 5 minutes. Place the dough in a lightly greased bowl, cover, and let rise for at least one hour. You can also place it in the refrigerator overnight and use it the next day.
