04 - 1 tablespoon unsalted butter
05 - 1 teaspoon granulated sugar
06 - ½ teaspoon salt

# Step-by-Step:
01 - Preheat oven to 400°F. Line a 9-inch tart pan with pastry, trim excess, and prick base with a fork. Chill in refrigerator for 10 minutes.
02 - Heat olive oil in a large skillet over medium heat. Add onions and cook, stirring frequently, for 10 minutes until softened. Add butter, sugar, salt, and thyme, then cook, stirring occasionally, until onions turn deep golden and caramelized, approximately 20 to 25 minutes. Remove from heat and allow to cool slightly.
03 - Whisk eggs, heavy cream, whole milk, black pepper, and salt together until smooth in a mixing bowl.
04 - Evenly spread caramelized onions over chilled pastry shell. Sprinkle crumbled goat cheese atop onions.
05 - Carefully pour egg mixture over the filling, ensuring even coverage.
06 - Bake for 25 to 30 minutes until filling is set and tart is lightly golden. Remove from oven and cool for 10 minutes.
07 - Garnish with chopped fresh chives or parsley and freshly cracked black pepper if desired. Serve warm or at room temperature.
