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

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease a baking dish (approximately 9-inch round or equivalent) with vegetable oil and set aside.

Step 2

Peel the onions and slice them into thin rings, approximately 1/4 inch thick.

Step 3

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.

Step 4

In a mixing bowl, whisk together the eggs, whole milk, and heavy cream until smooth.

Step 5

Sprinkle the flour into the egg mixture, whisking constantly to avoid lumps. Add sea salt, black pepper, and nutmeg, and whisk until fully incorporated.

Step 6

Gently stir in the grated Parmesan cheese and fresh thyme leaves.

Step 7

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.

Step 8

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.

Step 9

Remove the dish from the oven and allow it to cool for 5-10 minutes before serving.

Step 10

Serve warm as a side dish or a light main course alongside a fresh green salad or crusty bread.
