Why make onion tart in the air fryer?
Benefits of the air fryer
The air fryer has found its way into many kitchens thanks to its ability to cook food quickly and with less fat. Many people associate the air fryer with deep-fried food, but it’s far more versatile than that. It works like a small convection oven, meaning it can quickly bake, roast and toast food using circulating hot air. That makes it a natural choice for tarts, like onion tart.
Here are some of the benefits of making onion tart in an air fryer:
- Time savings:The air fryer heats up faster than a traditional oven, reducing the cooking time.
- Energy savings:Since the air fryer is smaller, it also uses less energy, making it more eco-friendly.
- Even baking:The circulating heat ensures an even bake of the tart.
- Flexibility:The air fryer makes it possible to prepare small portions, which is perfect for smaller households or quick meals.
Healthier tart
One of the great benefits of making tarts in an air fryer is that you can use less fat while still achieving a crispy crust. This makes the tart a little lighter than a traditional tart, which often uses more butter or oil to achieve the same crispiness.
Where does onion tart come from?
The tart’s history
Tarts have a long history that goes all the way back to antiquity, when Greeks and Romans made simple wheat tarts filled with various ingredients. In the Middle Ages, tarts became popular in Europe, where they were used as a practical meal for both rich and poor. The earliest tarts often had a thick crust made of dough that mostly served as a container for the filling. This dough was often so hard that it wasn’t eaten, but used solely to hold the filling during baking.
Onion tart and its origins
Although tarts have a long history, onion tart is a dish especially associated with French cuisine. In the Alsace region of northeastern France, onion tart, also known as “Tarte à l’oignon,” is a classic. This tart is filled with caramelized onions, eggs and cream, giving it a rich and creamy flavor. The dish is a great example of how French cooking uses simple ingredients to create rich and flavorful dishes.
Onion tart was originally eaten as an everyday dish, where ingredients like onions and eggs were easy to find and cheap. Today, the tart has become more widely popular and can be found in many different variations and countries.
Variations of onion tart
Onion tart is a versatile dish that can easily be adapted to different taste preferences and diets. Here are some variation ideas you can try:
1. Adding meat
If you want a heartier tart, you can add meat to the recipe. Here are some popular choices:
- Bacon:Add crispy fried bacon for an extra dimension of flavor.
- Ham:Diced ham can add a salty, rich flavor.
- Chorizo:If you want to add a spicy twist, chorizo can be an excellent addition.
2. Vegetarian variations
For those who prefer a vegetarian version, it’s easy to experiment with different vegetables.
- Spinach:Fresh spinach can be added to the filling to give a fresh, green flavor.
- Mushrooms:Mushrooms, especially button mushrooms, pair well with onions and give the dish more umami.
- Tomato:Slices of fresh tomato on top can add both color and a tangy contrast to the sweet onion filling.
3. Gluten-free tart
If you’re gluten intolerant, you can use a gluten-free tart dough or replace the traditional dough with a base made from chickpea flour, cauliflower or another gluten-free base.
4. Cheese types
Cheese plays an important role in the onion tart, but you can vary the type of cheese depending on taste:
- Cheddar:A sharp cheddar gives a rich and bold flavor.
- Gruyère:For a more classic French flavor, try Gruyère, which is both nutty and mild.
- Feta:Feta can add a salty, creamy texture to the tart.
5. Vegan options
It’s also possible to make a vegan version of the onion tart by replacing some of the animal-based ingredients:
- Replace the eggs with chickpea flour:Or another egg substitute.
- Use vegan cheese:Instead of regular cheese.
- Swap the cream for plant-based alternatives:Such as coconut milk, oat cream or soy cream.
Try adding a splash of balsamic vinegar to the onions while they caramelize. It brings out the sweetness in the onions and gives the tart extra depth and a rich flavor that takes the dish to a new level

Tips for onion tart in the air fryer
Most air fryers have a baking function, but there are a few things you should keep in mind when making onion tart in an air fryer:
- Watch out for overcrowding:The air fryer is smaller than a regular oven, so make sure the tart pan fits.
- Check the temperature regularly:Air fryers can sometimes cook things faster than a regular oven. Keep an eye on the tart to avoid burning it.
- Baking time:Start with the recommended time, but keep in mind that air fryers can vary in baking time. Poke the center of the tart to make sure it’s cooked through.
I recommend this elegant white wine for our onion tart
Onion tart has a natural sweetness from the caramelized onions and a rich, creamy texture from eggs and crème fraîche – and that calls for a white wine with freshness and acidity that can cut through the richness and bring out the sweetness. A dry, mineral Soave does exactly that: it brings a lovely balance with its light fruitiness and clean finish. I can warmly recommend iLatium Morini Le Calle Soave 2023 – an Italian classic from Veneto that pairs perfectly with a rich, flavorful onion tart from the air fryer.
Conclusion

The crispy crust and soft filling make the tart a versatile dish that can be served as either a main course or a side dish. By making the tart in an air fryer, you save both time and energy, and the result is just as delicious as in a traditional oven. At the same time, you can play around with different variations of the dish, whether you want to add meat, experiment with different cheeses or try a vegan version.

FAQ
No, it’s not necessary. The filling goes straight into the raw crust, and 20-25 minutes at 180 °C (350 °F) is enough to bake the crust through. If you want an extra crispy crust, you can pre-bake it for 5-7 minutes before you spread the onions and pour over the egg mixture.
It depends on your air fryer, but most baskets fit a pan about 18-20 cm (7-8 inches) in diameter. Measure the bottom of the basket before you buy a pan, and make sure there’s a little space around it so the hot air can circulate. The 225 g (7.9 oz) of tart dough in the recipe is a good fit for a pan that size.
Yes, absolutely. Ready-rolled tart dough from the refrigerated section saves time and gives a great result. Use about 225 g (7.9 oz), as in the recipe, and trim the dough to fit your pan.
