Yield

Difficulty Level
Medium – ideal for cooks comfortable with dough handling and slow caramelization but approachable with guided steps.
Ingredients
- For the Caramelized Onions:
- 4 large yellow onions, thinly sliced
- 3 tbsp unsalted butter
- 2 tbsp extra virgin olive oil
- 1 tsp granulated sugar
- 1/2 tsp kosher salt
- 2 tbsp dry white wine (optional)
- Freshly ground black pepper, to taste
- For the Tartlet Dough:
- 2 cups all-purpose flour, sifted
- 1 tsp kosher salt
- 1 tbsp granulated sugar
- 1 cup (2 sticks) cold unsalted butter, cubed
- 1 large egg
- 3-4 tbsp ice-cold water
- For the Filling:
- 1 1/2 cups grated Gruyere cheese (preferably aged 6-12 months)
- 2 large eggs
- 1/2 cup heavy cream
- Fresh thyme leaves (optional), for garnish
Instructions
- Prepare the Caramelized Onions: Heat the butter and olive oil in a large heavy-bottomed skillet over medium-low heat. Add the thinly sliced onions, sprinkle with sugar and salt, and stir well.Sauté slowly for 35-40 minutes, stirring every 5 minutes to ensure even browning without burning. Once onions are deep golden and silky, deglaze with white wine if using, cook out the alcohol, and season with freshly ground black pepper. Set aside to cool.
- Make the Tartlet Dough: In a food processor, pulse the flour, salt, and sugar together. Add cold butter cubes and pulse until mixture resembles coarse crumbs with pea-sized bits. In a small bowl, whisk egg and 3 tbsp ice-cold water. Gradually add egg mixture while pulsing until dough just comes together. avoid overmixing.
- Turn dough onto a lightly floured surface,gently press together,flatten into a disk,wrap in plastic wrap,and refrigerate for at least 1 hour to rest and chill.
- Roll and Shape Tartlets: Preheat oven to 375°F (190°C). Remove dough from refrigerator, divide into 12 equal pieces. Roll each piece into a 3.5-inch circle,about 1/8 inch thick. Fit each into a tartlet tin or muffin pan cups, gently pressing and trimming edges.
- Blind Bake the Tartlet Shells: Line each dough shell with parchment paper and fill with pie weights or dried beans. Bake for 10 minutes, remove weights and parchment, then bake 5 more minutes until edges start to turn lightly golden.
- Prepare the Filling: in a medium bowl, whisk eggs and heavy cream until smooth. Stir in caramelized onions and grated Gruyere cheese until evenly combined.
- Assemble and Bake: Spoon filling evenly into each pre-baked tartlet shell. Bake for 15-20 minutes, or until the filling is set and tops are lightly golden. Remove and let cool slightly before unmolding or serving.
Expert Tips for Success
- Use yellow onions for a naturally sweet base, and allow the caramelizing process to be slow and patient; rushing or increasing the heat risks bitterness.
- Choose an aged Gruyere cheese for stronger, nutty flavors and smooth melting; avoid pre-shredded cheeses with additives to ensure proper melt and texture.
- Chill tartlet dough thoroughly to relax gluten strands-this ensures flaky, buttery layers after baking.
- Don’t skip blind baking; it prevents soggy bases and keeps the shells crisp under the moist filling.
- Make tartlets up to a day in advance,store covered in the fridge,then rewarm gently before serving to retain freshness.
Serving Suggestions
Present the tartlets warm or at room temperature alongside a vibrant arugula salad dressed with lemon vinaigrette to cut through the richness.Garnish each tartlet with fresh thyme sprigs or a light drizzle of balsamic glaze for an elegant but effortless finish. These are perfect for brunch spreads, cocktail parties, or as an indulgent snack with a glass of dry white wine like a crisp Sauvignon Blanc.
