Ingredients

• 2 tablespoons Unsalted butter
• 4 large Yellow onions
• 1 teaspoon Granulated sugar
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 1 tablespoon All-purpose flour
• 0.75 cup Whole milk
• 0.25 cup Heavy cream
• 2 large Eggs
• 1.5 cups Shredded Gruyère cheese
• 1 Pie crust (store-bought or homemade)
• 1 teaspoon Fresh thyme leaves

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

In a large skillet, melt the butter over medium heat.

Step 3

Slice the yellow onions into thin rings and add them to the skillet. Stir to coat the onions in the melted butter.

Step 4

Sprinkle the onions with the sugar, 1 teaspoon of salt, and black pepper. Cook, stirring frequently, until the onions are golden brown and caramelized (about 20 minutes).

Step 5

Sprinkle the flour over the caramelized onions and cook for an additional 1-2 minutes, stirring to combine.

Step 6

Gradually add the milk and heavy cream to the skillet, stirring constantly, until the mixture thickens slightly. Remove from heat and let cool for 5 minutes.

Step 7

In a medium bowl, whisk together the eggs. Slowly add the cooled onion mixture to the eggs while whisking to avoid scrambling.

Step 8

Stir in the shredded Gruyère cheese and fresh thyme leaves.

Step 9

Roll out the pie crust into a 9-inch pie dish, pressing it gently into the edges. Trim any excess crust hanging over the sides.

Step 10

Pour the onion filling into the prepared pie crust, spreading it evenly.

Step 11

Bake in the preheated oven for 35-40 minutes, or until the filling is set and the crust is golden brown.

Step 12

Remove the pie from the oven and let it cool for 10 minutes before slicing and serving.

Step 13

Serve warm or at room temperature, garnished with additional thyme if desired.
