Apple and Onion Tarte Tatin: A Rustic Delight

The first time I encountered a tarte tatin, it was in a tiny Parisian bistro. The aroma of caramelized sugar and apples filled the air, an irresistible siren song leading me closer. The warm, sticky sweetness, balanced by the tartness of the apples and the buttery pastry, was a revelation. I knew right then that I had to learn how to recreate this magic myself, and while my first attempts were… well, let’s just say they were learning experiences, the journey ultimately led to this beautiful and savory Apple and Onion Tarte Tatin, a testament to the power of unexpected flavor combinations.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 30 minutes
• Total Time: 1 hour
• Servings: 6-8
• Yield: 1 11-inch tarte tatin
• Dietary Type: Vegetarian (can be easily adapted to vegan)

Ingredients

For the Dough:

• 200 g whole wheat flour (or whole spelt flour)
• ¼ teaspoon dried rosemary
• ¼ teaspoon rubbed sage
• ¼ teaspoon dried thyme
• ⅛ teaspoon garlic powder
• ⅛ teaspoon fresh ground black pepper
• ⅛ teaspoon cayenne pepper
• 100 g parmesan cheese, grated (omit for vegan)
• 50 g tahini
• 50 ml water
• 1 egg, beaten (substitute with 2 tablespoons aquafaba for vegan)

For the Filling:

• 2 tablespoons demerara sugar
• 1 tablespoon oil (garlic-infused oil recommended)
• 2 tablespoons balsamic vinegar
• 3 small apples, washed, cored, and quartered
• 1 large onion, chopped

Equipment Needed

• Large mixing bowl
• Cling film
• Rolling pin
• 28 cm/11 inch pie dish (oven and stovetop safe) or oven-safe pan
• Serving platter

Instructions

1. Prepare the Dough: In a large bowl, combine the whole wheat flour, dried rosemary, rubbed sage, dried thyme, garlic powder, black pepper, cayenne pepper, and grated parmesan cheese. Whisk together to evenly distribute the spices and cheese.
2. Incorporate Wet Ingredients: Add the tahini, water, and beaten egg to the dry ingredients.
3. Knead the Dough: Knead the ingredients together until a smooth dough forms. If the dough seems too dry, add a little more water, one teaspoon at a time, until it comes together. If it’s too wet, add a bit more flour.
4. Chill the Dough: Wrap the dough in cling film and chill in the refrigerator for at least 15 minutes. This allows the gluten to relax, resulting in a more tender crust.
5. Prepare the Caramel: Place the demerara sugar in the pie dish (or oven-safe pan) that can be directly heated on the stovetop. Ensure your pie dish is rated for both oven and stovetop use to prevent accidents.
6. Melt the Sugar: Over medium-high heat, melt the sugar. This will take about 4 minutes. The sugar will turn light in color but might still appear granulated.
7. Even Caramelization: Swirl the pan around carefully (the pan and sugar will be hot) while the sugar melts to ensure even melting and prevent burning.
8. Add Oil and Vinegar: Turn the heat down to low and add the oil and balsamic vinegar. Be careful, as this mixture might splatter.
9. Simmer: Allow the mixture to simmer for 1 minute, stirring gently to combine.
10. Arrange Filling: Remove the pan from the heat and arrange the chopped onion and quartered apples on top of the caramel syrup in the pie dish. Arrange them snugly but not overcrowded.
11. Roll Out the Dough: On a lightly floured surface, roll out the chilled dough so that it is slightly larger than the diameter of the pie dish.
12. Top the Filling: Carefully place the rolled-out dough on top of the filling, covering it completely. Press the edges of the dough down along the inside rim of the pie dish to seal in the filling. You can create a decorative edge by crimping the dough with a fork.
13. Bake: Bake in a preheated oven at 180°C/350°F (160°C fan) for 30 minutes, or until the crust is golden brown and the syrup is bubbling.
14. Rest: Allow the tarte tatin to rest for 10 minutes after baking. This will help the caramel to set slightly.
15. Invert: Place a serving platter on top of the pie dish. Carefully and confidently invert the tarte tatin onto the platter. Be cautious, as the caramel will be very hot.
16. Serve: Serve warm and enjoy!

Expert Tips & Tricks

• Garlic-Infused Oil: Using a garlic-infused oil adds a subtle but noticeable layer of flavor to the caramel. If you don’t have any on hand, you can infuse your own by gently heating a few cloves of garlic in olive oil until fragrant, then removing the garlic.
• Don’t Overcrowd: Avoid overcrowding the apples and onions in the filling. This can prevent them from caramelizing properly. It’s better to use slightly less filling than to pack it in.
• Prevent a Soggy Crust: For a crispier crust, you can blind-bake the dough for a few minutes before adding the filling. To do this, prick the dough all over with a fork and bake for 5 minutes before adding the apple and onion mixture.
• Caramel Consistency: Watch the caramel carefully as it melts. It should turn a light amber color. If it gets too dark, it will taste burnt. Remove from heat immediately if you see smoke.
• Temperature Control: Keep a close eye on the oven temperature. If the crust starts to brown too quickly, you can cover the tarte with foil for the remaining baking time.
• Dough Alternatives: If you’re short on time, you can use store-bought puff pastry instead of making your own dough. Just make sure to adjust the baking time accordingly.

Serving & Storage Suggestions

This Apple and Onion Tarte Tatin is best served warm, either as an appetizer, a main course accompanied by a side salad, or even as a dessert. A dollop of crème fraîche, a scoop of vanilla ice cream (dairy or non-dairy), or a drizzle of balsamic glaze will elevate the presentation and flavor.

Leftovers can be stored in the refrigerator for up to 3 days. To reheat, warm in a preheated oven at 175°C/350°F until heated through. The crust may lose some of its crispness upon reheating. While not recommended, you can freeze the tarte, but expect changes in texture and caramel consistency upon thawing.

Variations & Substitutions

• Gluten-Free: Use a gluten-free flour blend for the dough. You may need to add a binding agent like xanthan gum.
• Vegan: Omit the Parmesan cheese and use 2 tablespoons of aquafaba in place of the egg. Ensure you are using a plant-based oil and not butter.
• Different Fruits: Substitute pears, quince, or figs for the apples.
• Cheese Variation: Use a different cheese, such as Gruyère or goat cheese, instead of Parmesan. Add the cheese in crumbles on top of the apples and onions before adding the dough.
• Herb Variations: Experiment with different herbs, such as rosemary, sage, or thyme. Add a pinch of red pepper flakes for a little kick.
• Maple Syrup: Substitute maple syrup for the demerara sugar for a more complex flavor.

FAQs (Frequently Asked Questions)

Q: Can I make this tarte tatin ahead of time?

A: While the tarte is best served fresh, you can prepare the dough and the filling separately in advance. Store the dough in the refrigerator and assemble the tarte just before baking.

Q: My caramel is burning. What should I do?

A: Remove the pan from the heat immediately and discard the burnt caramel. Start again with a fresh batch of sugar, being sure to watch it closely.

Q: The apples are not cooking through evenly. How can I fix this?

A: Ensure the apples are cut into uniform sizes and arranged evenly in the pan. If they are still not cooking through, you can partially cook them in a pan before adding them to the tarte.

Q: Can I use a different type of onion?

A: Yes, you can use any type of onion you like, such as red onion, yellow onion, or shallots. The flavor will vary slightly depending on the type of onion you use.

Q: My crust is soggy. What did I do wrong?

A: A soggy crust can be caused by too much moisture in the filling or by not baking the tarte long enough. Make sure to arrange the filling evenly and bake the tarte until the crust is golden brown and crisp. You can also try blind-baking the crust before adding the filling.
