Recipe Information
Ingredients
- 2 medium yellow onion
- 2 tablespoons butter
- 4 large eggs
- 1.5 cups whole milk
- 0.5 cups heavy cream
- 1 tablespoon all-purpose flour
- 1 teaspoon fine sea salt
- 0.5 teaspoons black pepper
- 0.25 teaspoons nutmeg
- 0.25 cups grated Parmesan cheese
- 1 teaspoon fresh thyme leaves
- 1 teaspoon vegetable oil
Instructions
Preheat your oven to 350°F (175°C). Grease a baking dish (approximately 9-inch round or equivalent) with vegetable oil and set aside.
Peel the onions and slice them into thin rings, approximately 1/4 inch thick.
In a large skillet, heat the butter over medium heat until melted. Add the sliced onions and cook for 8-10 minutes, stirring occasionally, until they are softened and lightly golden. Remove from heat and set aside.
In a mixing bowl, whisk together the eggs, whole milk, and heavy cream until smooth.
Sprinkle the flour into the egg mixture, whisking constantly to avoid lumps. Add sea salt, black pepper, and nutmeg, and whisk until fully incorporated.
Gently stir in the grated Parmesan cheese and fresh thyme leaves.
Spread the cooked onions evenly across the bottom of the prepared baking dish. Pour the custard mixture over the onions, ensuring they are evenly submerged.
Place the baking dish in the preheated oven and bake for 35-40 minutes, or until the custard is set and lightly golden on top. To check doneness, insert a knife into the center; it should come out clean.
Remove the dish from the oven and allow it to cool for 5-10 minutes before serving.
Serve warm as a side dish or a light main course alongside a fresh green salad or crusty bread.
