Ingredients:
- 1 1/4 cups (150g) all-purpose flour, plus more for dusting
- 1/2 teaspoon (2g) salt
- 1/2 cup (1 stick/113g) unsalted butter, very cold and cubed
- 1/4 cup (60ml) ice water
- 2 tablespoons (30ml) olive oil
- 1 small yellow onion, finely chopped (about 1/2 cup)
- 2 cloves garlic, minced
- 2 (13.5 ounce) cans canned spinach, well-drained and squeezed dry
- 1 (14 ounce) can artichoke hearts, drained and quartered
- 1/2 cup (120ml) heavy cream
- 1/4 cup (60ml) grated Parmesan cheese
- 1/2 cup (50g) grated Gruyère cheese, plus more for topping
- 1 large egg, lightly beaten
- 1 tablespoon lemon zest
- 1/4 teaspoon grated nutmeg
- Salt and freshly ground black pepper to taste
- 1 large egg, beaten (for egg wash)
Instructions:
- Pulse flour and salt in a food processor. Add cold butter and pulse until the mixture resembles coarse crumbs. Slowly add ice water until the dough just comes together. Form into a disc, wrap in plastic wrap, and chill for at least 30 minutes.
- Heat olive oil in a skillet over medium heat. Sauté onion until softened, then add garlic and cook until fragrant.
- Stir in the drained canned spinach and artichoke hearts. Cook for a few minutes to evaporate excess moisture.
- Stir in heavy cream, Parmesan cheese, Gruyère cheese, egg, lemon zest, and nutmeg. Season with salt and pepper. Cook until the mixture is heated through and slightly thickened.
- On a lightly floured surface, roll out the pastry to about 1/8 inch thickness. Use a cookie cutter or knife to cut out circles slightly larger than the muffin tin cups.
- For an extra crispy shell and to avoid a soggy base, blind bake the crusts : Place baking paper and baking beans and bake for 10 minutes, then add the filling and bake again
- Gently press the pastry circles into the muffin tin cups. Fill each cup with the spinach and artichoke mixture. Top with additional Gruyère cheese.
- Brush the pastry edges with egg wash. Bake in a preheated oven at 375°F (190°C) for 25-30 minutes, or until the pastry is golden brown and the filling is set.
- Let the tartlets cool in the muffin tin for a few minutes before transferring them to a wire rack to cool completely. Serve warm or at room temperature.
