Savory Gruyere and Caramelized Onion Tartlets

Picture yourself in a cozy kitchen, the aroma of caramelized onions wafting through the air, and the anticipation of a delectable treat. This is what you’ll experience when you make our Savory Gruyere and Caramelized Onion Tartlets. These delightful tartlets are a perfect combination of rich, creamy Gruyere cheese and sweet, caramelized onions, all nestled in a flaky pastry shell.


  • 1 sheet of puff pastry
  • 2 large onions, thinly sliced
  • 2 tablespoons of butter
  • 1 cup of grated Gruyere cheese
  • 1/4 teaspoon of thyme leaves
  • Salt and pepper to taste


  1. Preheat your oven to 375°F (190°C).
  2. In a pan, melt the butter over medium-low heat. Add the thinly sliced onions and cook them slowly until they become soft and caramelized, about 20-25 minutes. Stir occasionally to prevent burning.
  3. While the onions are caramelizing, roll out the puff pastry sheet and cut it into small squares or circles, depending on your preference.
  4. Once the onions are caramelized, season them with thyme, salt, and pepper.
  5. Place a spoonful of the caramelized onions and a generous sprinkle of Gruyere cheese onto each pastry square or circle.
  6. Bake in the preheated oven for 15-20 minutes, or until the pastry is golden brown and the cheese is bubbling and slightly browned.
  7. Remove from the oven and let the tartlets cool for a few minutes before serving.
