This savory creation is suitable for brunch, lunch, or a light dinner. The harmony of sweet onions and rich custard delivers a flavorful and comforting experience.

Ingredients

• 1 9-inch pie crust, unbaked
• 2 large onions, thinly sliced
• 1 cup heavy cream
• 3 large eggs
• 1/2 tsp nutmeg, freshly grated
• 1/2 cup gruyère cheese, grated

Instructions

1. Preheat the oven to 375°F (190°C).
2. Place the unbaked 9-inch pie crust into a tart pan, pressing gently to fit the edges.
3. In a skillet, heat 2 tablespoons of olive oil over medium heat. Add the thinly sliced onions and cook, stirring occasionally, until they are deep golden brown and caramelized, about 20 minutes.
4. In a mixing bowl, combine the heavy cream, eggs, freshly grated nutmeg, and grated Gruyère cheese. Whisk until the mixture is smooth and well combined.
5. Spread the caramelized onions evenly over the pie crust in the tart pan.
6. Pour the cream and egg mixture over the onions, ensuring it is evenly distributed.
7. Bake the tart in the preheated oven for 45 minutes, or until the custard is set and the top is golden brown.
8. Remove the tart from the oven and let it cool for at least 10 minutes before slicing and serving.
