Ingredients

  • 1 sheet frozen puff pastry

    thawed in refrigerator

  • 2 tablespoons extra-virgin olive oil
  • 3 large Vidalia onions or other sweet variety

    thinly sliced

  • 4 thyme sprigs

    plus more for garnish

  • Kosher salt and freshly cracked black pepper
  • 1/3 cup good quality beef stock

Directions

  1. 1

    Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.

  2. 2

    On a work surface, roll the puff pastry into a roughly 10 by 16-inch rectangle. With a sharp knife, trim uneven edges to make a perfect rectangle. Evenly cut off the outer 1 inch of each side of the rectangle in strips; put the puff sheet on the baking sheet. Dip your finger in water and run around the top edges of the rectangle and replace the removed strips of pastry along the edges of the sheet, pressing lightly to adhere. With a fork, pierce the interior of the tart shell to prevent rising; do not pierce the adhered edges. Bake until the outer edges have puffed and are golden in color; about 15 minutes. Set aside.

  3. 3

    Heat 2 tablespoons olive oil in a large skillet over medium-low heat. Add onions and thyme sprigs and season well with salt and pepper, to taste. Cook, stirring occasionally, until the onions begin to brown. Add the stock, a tablespoon at a time, as the pan gets dry, scraping and stirring the brown bits that are stuck to the bottom oft the pan. When the onions are caramelized to a dark golden color, remove from the heat and discard the leafless thyme sprigs (the leaves fall off while cooking).

  4. 4

    When ready to serve, preheat the oven to 350 degrees F. Evenly spread the caramelized onions on the cooked pastry shell and heat in the oven until warmed through, 5 to 7 minutes. Remove from oven, to a cutting board and cut into wedges. Arrange on a serving platter and garnish each wedge with a sprig of fresh thyme. Serve immediately and enjoy!

French Onion Panade

French Onion Panade

Panade is the French country cook's answer to stuffing — a satisfying and efficient way to use up stale bread. Because there are so few components, taking care to ensure that each one is just right will make all the difference in how the final dish tastes. Start with a stale, crusty loaf of sourdough bread. Cook the onions slowly, until they're a deep caramel color, and then season them properly with vinegar and wine. Buy good Gruyère and Parmesan, and grate it yourself. And finally, use either homemade chicken stock, or buy some from a butcher. The result will be triumph of upcycling: basically French onion soup without the soup — just bite after bite of cheesy, onion-and-stock-soaked bread. Serve it as a main course, with a light green salad and a dry white wine or an ice-cold beer.

About this Recipe

Craving a sophisticated yet surprisingly simple dish that captures the comforting essence of classic French cuisine? This elegant French Onion Tart delivers a show-stopping savory experience with minimal fuss, making it perfect for entertaining or a delightful weeknight treat.

This recipe shines by focusing on high-quality ingredients and straightforward preparation. The secret lies in the masterful transformation of sweet Vidalia onions into a deeply caramelized, flavorful base, elevated by a touch of good quality beef stock. All of this is nestled within a golden, flaky crust provided by readily available frozen puff pastry, turning a few humble components into something truly extraordinary.

Prepare for a delightful contrast of textures and flavors. You'll savor the rich, melt-in-your-mouth tenderness of slow-cooked onions, their inherent sweetness intensified and balanced by a savory depth from the beef stock. Each bite offers the delicate crunch and airy flakiness of the puff pastry, creating a harmonious balance. The subtle, earthy notes of fresh thyme weave through the sweet and savory layers, adding an aromatic finish that makes this tart feel wonderfully indulgent.

Customization & Variations

While delicious as is, you can easily adapt this tart. The recipe specifies Vidalia onions, but feel free to experiment with other sweet varieties like Walla Walla or Maui onions. For a deeper, more complex flavor, you could even mix in some red onions during the caramelization process. Remember, the key is to allow the onions ample time to truly caramelize for that signature sweetness.

This French Onion Tart makes an impressive appetizer for a dinner party, a wonderful addition to a brunch spread, or a satisfying light lunch when paired with a crisp green salad. Serve it warm, garnished with a few fresh thyme sprigs, for an inviting presentation.
