Ingredients

Scale

Vegetables and Herbs

  • 3 large sweet yellow or Vidalia onions, thinly sliced
  • 1 teaspoon fresh thyme leaves, plus extra for garnish
  • 1 clove garlic, minced
  • Salt and freshly ground black pepper, to taste

Dairy

  • 1 cup Gruyère cheese, shredded
  • 4 ounces cream cheese, softened to room temperature
  • 2 tablespoons unsalted butter

Pastry

  • 1 sheet high-quality pre-rolled puff pastry (use gluten-free for dietary needs)

Instructions

  1. Prepare the Onions: Slice onions thinly. In a large skillet over low heat, melt unsalted butter and slowly cook the onions, stirring occasionally, until they are golden brown and soft, about 30-40 minutes. Add minced garlic towards the end and season with salt and pepper. This slow caramelization enhances the natural sweetness of the onions.
  2. Prepare the Pastry Base: Lightly flour a surface and roll out the puff pastry sheet to fit your tart pan. Gently press the pastry into the pan and prick the bottom with a fork. Pre-bake in a preheated oven at 375°F (190°C) until lightly golden, about 10-12 minutes.
  3. Mix the Cheese Filling: In a bowl, combine shredded Gruyère and softened cream cheese. Add a pinch of fresh thyme, salt, and pepper. Mix until smooth and evenly blended.
  4. Assemble the Tart: Spread a thin layer of the cheese mixture evenly over the pre-baked crust. Top with an even layer of the caramelized onions, allowing flavors to meld during baking.
  5. Bake Until Perfection: Bake the assembled tart at 375°F (190°C) for 20-25 minutes, or until the cheese is bubbly and the crust is a deep golden brown.

Notes

  • Patience Is Key: Slowly caramelize onions to develop sweetness and avoid bitterness.
  • Use Room Temperature Cheese: This ensures the cheese mixture blends smoothly and spreads easily.
  • Don’t Overfill: Keep toppings in moderate layers to maintain crispness of the crust.
  • Chill the Dough: Keep pastry cold before baking to preserve a flaky texture.
  • Let It Rest: Allow the tart to cool slightly before slicing for clean, neat pieces.
