Why This Onion Pie Recipe Works
EASY-TO-MAKE DOUGH - Anyone can make this dough. You don't need special skills or fancy equipment, just a bowl, your hands, and a little bit of time.
MAKE AHEAD OPTION - This recipe is great for meal planning. You can make the dough and filling a day ahead, making the day of cooking a breeze.
FLAVORS - The smokiness of bacon, the sweetness of caramelized onions, and the richness of Swiss cheese create a real crowd-pleaser dinner.
ONE-PAN FILLING - The filling gets cooked in one pan, making cleanup a breeze.
Ingredients
Please check the recipe card below for a detailed, printable ingredient list.
FLOUR - The foundation of your crust. All-purpose flour is perfect for this recipe. For a healthful twist, you could use whole wheat, but it will alter the texture and taste slightly.
WATER - Lukewarm water is best as it will help activate the yeast more effectively, resulting in a fluffier crust.
BUTTER - Choose a high-quality unsalted butter. Since this is a simple dough, the better your butter, the better your crust will be.
DRY YEAST - Opt for instant yeast if you can find it. It'll make your dough rise more quickly and evenly.
SUGAR - Just a touch of sugar helps to balance the flavors and feed the yeast, encouraging a good rise.
ONIONS - Yellow or white onions are ideal. They caramelize beautifully and offer a natural sweetness.
BACON - Opt for thick-cut bacon if possible. It holds up better and delivers a more robust flavor.
OLIVE OIL - I recommend extra-virgin olive oil. Good quality oil adds an extra layer of richness.
LARGE EGGS - Fresh, farm-raised eggs offer the best flavor.
HEAVY CREAM - Full-fat is best to get that lush texture we're aiming for.
SWISS CHEESE - Opt for freshly grated cheese over pre-packaged for a smoother, meltier finish.
How To Make Onion Pie (German Zwiebelkuchen)
Please check the printable recipe card below for more detailed instructions.
- KNEAD THE DOUGH - Mix all dough ingredients in a large bowl until smooth. Let it rest for 30 minutes.
- COOK THE FILLING - Fry bacon in a pan until it starts to crisp, then add onions until softened.
- PREPARE EGG MIXTURE - In a separate bowl, beat eggs, heavy cream, nutmeg, and salt.
- ASSEMBLE AND BAKE - Layer dough in the pan, add the onion and bacon mixture, pour the egg mixture on top, and finish with grated Swiss cheese. Bake for 30 minutes at 400º Fahrenheit.
Leftovers
STORE - Got leftovers? No problem. Place them in an airtight container and stash them in the fridge. They'll stay good for up to 3 days, making for a delicious grab-and-go option for busy weekdays.
FREEZE - If you find more than you can eat, wrap individual slices in cling film, place them in a ziplock bag, and then into the freezer. This way, you can enjoy a slice whenever the craving strikes for up to a month.
REHEAT - The oven is your friend when reheating this pie. Just set the temperature to 350º Fahrenheit and heat for about 15 minutes. This method helps maintain the crust's texture while reviving the filling's creaminess.
