# Instructions:
01 -
Combine 1 1/2 cups all-purpose flour and 1/2 tsp salt in a large bowl. Cut in 1/2 cup (1 stick) very cold unsalted butter until pea-sized. Gradually add 1/4 cup ice water, mixing until just combined. Form into a disc, wrap, and chill for at least 30 minutes.
02 -
In a large skillet, heat 2 tbsp olive oil over medium-low. Add 3 large yellow onions, thinly sliced, and cook slowly for 20-25 minutes until very soft and golden. Stir in 2 cloves minced garlic, 1 tbsp fresh thyme leaves, and 1 tsp fresh rosemary for the aromatic base of your Savory Onion and Herb Tart with Creamy Cheese. Deglaze with 1/4 cup dry white wine, cooking until evaporated.
03 -
In a bowl, whisk together 3 large eggs, 1 1/2 cups heavy cream, and 1/2 cup whole milk. Stir in 4 oz shredded Gruyère cheese and 1/4 tsp freshly grated nutmeg. Season generously with salt and freshly ground black pepper to taste. This rich custard is key to your Savory Onion and Herb Tart with Creamy Cheese.
04 -
Preheat oven to 375°F. Roll chilled dough into a 12-inch circle and fit into a 9-inch tart pan. Trim edges. Line with parchment paper, fill with pie weights, and par-bake for 15 minutes. Remove weights and parchment, then bake for another 5 minutes until lightly golden.
05 -
Spread the caramelized onion mixture evenly into the par-baked tart shell. Pour the creamy cheese custard over the onions. Carefully transfer the tart to the oven. Bake for 30-35 minutes, or until the custard is set and golden brown, ensuring a perfect Savory Onion and Herb Tart with Creamy Cheese.
06 -
Remove the tart from the oven and let it cool on a wire rack for at least 10-15 minutes before slicing. This allows the custard to fully set, making for cleaner slices of your delicious Savory Onion and Herb Tart with Creamy Cheese. Serve warm or at room temperature.
# Notes:
01 -
For an extra flaky crust, ensure your butter and water are *very* cold. You can even freeze the butter cubes for 10 minutes before mixing.
02 -
Leftover tart can be stored covered in the refrigerator for up to 3 days. Reheat gently in a 300°F oven until warmed through.
03 -
Feel free to experiment with other cheeses! Swiss, Comté, or even a sharp white cheddar can be delicious alternatives to Gruyère.
04 -
This tart is wonderful served with a simple green salad dressed with a light vinaigrette, or as part of a brunch spread.
