Ingredients You’ll Need

Gather these high-quality ingredients to craft a fine dining-worthy onion tart.

For the Tart Crust:

  • 1 ¼ cups all-purpose flour
  • ½ cup unsalted butter, chilled and cubed
  • ¼ tsp sea salt
  • 1 egg yolk
  • 2 tbsp ice water

For the Caramelized Onion Filling:

  • 4 large yellow onions, thinly sliced
  • 2 tbsp unsalted butter
  • 1 tbsp olive oil
  • 1 tbsp aged balsamic vinegar
  • 1 tsp fresh thyme leaves
  • ½ tsp salt
  • ¼ tsp freshly ground black pepper

For the Garnishes & Plating:

  • 2 oz fresh goat cheese (chèvre)
  • 1 tbsp heavy cream (for a smooth goat cheese quenelle)
  • Aged balsamic reduction
  • Parmesan shavings
  • Microgreens & chive blossoms

Step 1: Prepare the Tart Crust

A perfectly crisp and buttery pastry base is essential for this fine dining tart.

Ingredients Used in This Step:

Flour, butter, salt, egg yolk, ice water

Method:

  1. Make the Dough: In a food processor, pulse flour, salt, and butter until the mixture resembles coarse crumbs.
  2. Bind the Dough: Add egg yolk and ice water, pulsing until a dough forms.
  3. Chill & Roll: Form into a disc, wrap in plastic, and chill for 30 minutes.
  4. Blind Bake: Roll out and press into tart molds. Prick with a fork, cover with parchment, and bake at 375°F (190°C) for 15 minutes until lightly golden.

💡 Pro Tip: For an ultra-crisp tart shell, brush the inside with a thin layer of beaten egg white before the final bake.


Step 2: Caramelize the Onions

The key to deep, rich flavor is slow-cooked, deeply caramelized onions.

Ingredients Used in This Step:

Onions, butter, olive oil, balsamic vinegar, thyme, salt, pepper

Method:

  1. Melt Butter & Oil: In a wide pan over low heat, melt butter and olive oil.
  2. Slow Cook the Onions: Add sliced onions and stir occasionally for 45 minutes, allowing them to slowly caramelize.
  3. Deglaze with Balsamic: Stir in balsamic vinegar to enhance the deep, umami flavor.
  4. Finish with Thyme: Add fresh thyme, salt, and pepper, then let cool slightly.

💡 Pro Tip: The onions should be jam-like, rich, and dark brown—patience is key!


Step 3: Assemble & Bake the Tart

Ingredients Used in This Step:

Baked tart crust, caramelized onion filling

Method:

  1. Fill the Tart Shell: Spoon a thick layer of caramelized onions into the pre-baked tart shell.
  2. Smooth the Surface: Use an offset spatula for a level, elegant finish.
  3. Bake Again: Return to the oven at 350°F (175°C) for 10 minutes to set the filling.

💡 Pro Tip: Let the tart rest for 5 minutes before plating for the best texture.


Step 4: Plate with Fine Dining Precision

Plating is key to elevating this dish into a Michelin-star-worthy presentation.

Ingredients Used in This Step:

Goat cheese, heavy cream, balsamic reduction, parmesan shavings, microgreens

Method:

  1. Make the Goat Cheese Quenelle: Whisk goat cheese with heavy cream until smooth. Use a warm spoon to shape into a sleek quenelle and place it atop the tart.
  2. Add Parmesan Shavings: Scatter thin curls of aged parmesan over the plate.
  3. Drizzle with Balsamic Reduction: Create an elegant swipe of aged balsamic across the plate.
  4. Garnish with Microgreens: A final sprinkle of microgreens and chive blossoms adds a fresh, delicate contrast.

💡 Pro Tip: Keep plating minimal yet artistic, using negative space for a modern aesthetic.
