Ingredients (serves 1–2)
- 250 g plain flour

- 1 pinch of salt
- 300 g onions
- 100 g bacon or ham
- 200 ml cream
- 2 eggs
- Pepper and nutmeg, to taste
Shopping for the ingredients
Fresh ingredients are essential when making onion tart. As you shop, pay close attention to the quality of the onions and the bacon, as these are the components that truly define the flavour of the dish. Visit a local market or a well-stocked supermarket to track down the best produce you can find.
Preparing the dish
Before you start cooking, a little thorough preparation makes all the difference. Slice the onions into fine rings and cut the bacon into small cubes. This ensures the flavours meld together beautifully as the tart bakes. Have all your utensils to hand too, so the whole process runs smoothly from start to finish.
Step-by-step instructions
- Combine the flour, butter and salt in a bowl and knead into a dough.
- Press the dough into a greased tart tin, forming a raised rim.
- Fry the onions and bacon in a pan until the onions are soft.
- In a separate bowl, whisk together the cream and eggs and season with pepper and nutmeg.
- Spread the onion and bacon mixture evenly over the dough.
- Pour the egg-and-cream mixture over the top.
- Bake in a preheated oven at 180°C for around 35–40 minutes.
Gluten-free / lactose-free version
To create a gluten-free version of the onion tart, simply swap the plain flour for a gluten-free alternative. For a lactose-free version, use lactose-free cream and margarine in place of butter. These small adjustments mean that people with particular dietary needs can enjoy the dish too. A little creativity in the kitchen makes it easy to adapt a traditional recipe to different lifestyles.
Tips for vegans and vegetarians
For a vegan take, replace the bacon with smoked tofu or mushrooms, both of which deliver a similar savoury aroma. Instead of eggs, a mixture of flaxseed and water works well to bind the filling. Plant-based cream is essential for keeping that lovely creamy consistency. With these swaps, vegans can enjoy all the hearty flavour of the onion tart.
More tips and tricks
A few simple tips can make your onion tart even more delicious. Caramelising the onions first lends the dish a gentle sweetness. Take care not to roll the dough too thin, so it holds the filling well. Seasoning matters too — experiment with herbs such as thyme or rosemary for extra depth of flavour.
Adapting the recipe to your taste
The onion tart is easy to tailor to your own preferences. Add more vegetables such as peppers or broccoli for a colourful variation, or fold in different cheeses for an interesting savoury note. Use the recipe as a foundation and let your imagination run free — much as you might with a rustic Flammkuchen.
Ingredient substitutions
If you do not have every ingredient to hand, there are plenty of alternatives. You can use yoghurt instead of cream for a lighter result, and if bacon is not for you, other protein sources such as pulses work nicely. The key is to keep the filling at the right consistency so the onion tart bakes up beautifully — the same balance that makes a good Speckkuchen so satisfying.
Drink pairing ideas
A range of drinks pairs well with a hearty onion tart. A dry white wine harmonises beautifully with its flavours and brings out the best in the dish. For an alcohol-free option, a fruity grape juice or a sparkling mineral water with a slice of lemon works a treat. These companions turn the meal into a truly memorable experience.
Serving and presentation ideas
The presentation of your onion tart can shape the whole experience. Serve it on a rustic wooden board and garnish with fresh herbs. A scattering of finely sliced onion rings and a side of green salad add welcome visual variety. An inviting presentation heightens the enjoyment and makes the dish even more tempting.
A bit of history
The onion tart has a long tradition and is known across many cultures. In Liechtenstein it is a classic, particularly in autumn when the onions are freshly harvested. Its role as a festive bake has roots in old customs and celebrations. Today the dish is associated with cosiness and conviviality — the pleasure of cooking and eating together with family and friends, and a wonderful window onto Liechtenstein cuisine.
