Description
A southern caramelized onion and goat cheese tart is a baked savory pastry that pairs sweet cooked onions with bold cheese. Nestled inside a crisp, golden puff pastry crust, the filling relies on a light egg and heavy cream custard to bind everything together into a smooth, sliceable pie. The signature flavor profile comes from combining aromatic yellow onions with butter, olive oil, a splash of balsamic vinegar, brown sugar, and earthy fresh thyme leaves.
Ingredients
Scale
For the Tart
- 1 sheet puff pastry, thawed
- 3 large yellow onions, thinly sliced
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 tablespoon brown sugar
- 1 tablespoon balsamic vinegar
- 1 teaspoon fresh thyme leaves
- 4 oz (115 g) goat cheese, crumbled
- 2 large eggs
- ½ cup heavy cream
- ¼ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon garlic powder
- 1 tablespoon chopped fresh parsley, for garnish
Instructions
- Preheat the oven: Preheat to 400°F (200°C). Lightly grease a 9-inch tart pan or pie dish.
- Prepare the pastry: Place the puff pastry into the pan, pressing it gently into the edges. Trim any excess pastry and prick the bottom several times with a fork.
- Caramelize the onions: Heat butter and olive oil in a large skillet over medium-low heat. Add the sliced onions and cook for 25–30 minutes, stirring occasionally, until deeply golden and soft.
- Add flavor: Stir in brown sugar, balsamic vinegar, thyme, salt, and pepper. Cook for another 2–3 minutes, then remove from heat.
- Make the filling: Whisk together the eggs, heavy cream, and garlic powder.
- Assemble: Spread the caramelized onions evenly over the pastry. Sprinkle the goat cheese on top, then pour the egg-and-cream mixture over everything.
- Bake: Bake for 30–35 minutes, or until the filling is set and the pastry is golden brown.
- Cool and garnish: Let the tart rest for 10 minutes before slicing. Garnish with fresh parsley and additional thyme if desired.
