Perfect for a comforting meal on a chilly day, this soup is both delicious and visually stunning with its golden-brown crust.

Instructions:

1. Preheat and Prepare: Preheat your oven to 400°F (200°C).
2. Caramelize the Onions:
- Heat the butter in a large pot over medium heat.
- Add the sliced onions and cook, stirring frequently, until they are golden brown and caramelized, about 15-20 minutes.
- Add the minced garlic and dried thyme, cooking for another 2 minutes until fragrant.
3. Simmer the Soup:
- Pour in the red wine, stirring to deglaze the pot, and cook until the wine is reduced by half.
- Add the beef broth and bay leaves. Bring the soup to a boil, then reduce to a simmer.
- Let the soup simmer for about 20-30 minutes to allow the flavors to meld.
- Add the chopped fresh parsley and season with salt and pepper to taste. Remove the bay leaves before serving.
4. Prepare the Puff Pastry:
- Roll out the puff pastry sheet on a lightly floured surface to ensure it's large enough to cover your soup bowls or ramekins.
- Cut the pastry into circles slightly larger than the diameter of the bowls.
5. Ladle Soup and Apply Pastry:
- Ladle the hot onion soup into oven-safe bowls or ramekins, leaving about half an inch of space from the top.
- Place a pastry circle over each bowl, pressing the edges to seal.
- Brush the top of the pastry with the beaten egg to ensure a golden, glossy finish.
6. Bake:
- Place the bowls on a baking sheet.
- Bake in the preheated oven for 15-20 minutes, or until the puff pastry is golden brown and puffed.
7. Serve:
- Carefully remove the bowls from the oven (they will be very hot).
- Allow them to cool slightly before serving.

Onion soup with pastry crust FAQ:

How long should I bake the puff pastry on top of the onion soup?

Bake the puff pastry for 15-20 minutes in a preheated oven at 400°F (200°C), or until it is golden brown and puffed.

What size bowls or ramekins should I use for the onion soup?

Use oven-safe bowls or ramekins that can hold about 1 to 1.5 cups of soup to ensure the pastry crust fits properly.

Can I use a different type of wine for this recipe?

Yes, you can substitute the red wine with a dry white wine or omit it entirely. If omitting, consider adding a splash of vinegar for acidity.

How should I store leftover onion soup with pastry crust?

Store the leftover soup in an airtight container in the refrigerator for up to 3 days. The pastry crust is best enjoyed fresh but can be reheated in the oven.

What can I use instead of puff pastry?

You can use phyllo dough as an alternative, layering several sheets brushed with butter, or make a biscuit topping for a different texture.

Cooking Tips:

- Caramelize the onions slowly over low heat to achieve the best flavor and ensure they become soft and sweet.

- Deglaze the pot with the red wine to incorporate all the flavorful bits stuck to the bottom.

- Use high-quality beef broth for a richer and more complex flavor.

- Make sure the puff pastry is fully thawed before placing it over the bowls to ensure even baking.

- Brush the pastry with beaten egg to get a beautifully golden and shiny crust.
