Recipe Information
Ingredients
- 3 tablespoons Unsalted butter
- 1 tablespoon Olive oil
- 4 large Yellow onions
- 1 teaspoon Sugar
- 1 teaspoon Salt
- 1 teaspoon Fresh thyme leaves
- 2 tablespoons All-purpose flour
- 1 cup Heavy cream
- 1.5 cups Gruyère cheese, shredded
- 3 large Eggs
- 1 9-inch crust Pre-made pie crust or homemade pie dough
Instructions
Preheat your oven to 375°F (190°C). If using homemade pie dough, roll it out and fit it into a 9-inch pie dish. Crimp the edges as desired. Place the crust in the refrigerator while preparing the filling.
In a large skillet over medium heat, melt the butter with the olive oil. Add the sliced onions and stir to coat them in the fat.
Cook the onions for 20-25 minutes, stirring occasionally, until they are golden brown and fully caramelized. Sprinkle the sugar and salt over the onions during the last 5 minutes of cooking to enhance their sweetness and draw out moisture.
Stir in the fresh thyme leaves and cook for 1 additional minute until fragrant. Sprinkle the all-purpose flour over the onions and stir well to coat. Cook for another 1-2 minutes to eliminate the raw flour taste.
Reduce the heat to low and stir in the heavy cream. Cook for 2-3 minutes, stirring frequently, until the mixture thickens slightly. Remove the skillet from heat and let the mixture cool for 5 minutes.
In a medium bowl, whisk together the eggs. Gradually add the slightly cooled onion mixture to the eggs, stirring constantly to prevent the eggs from curdling. Fold in the shredded Gruyère cheese.
Pour the onion mixture into the prepared pie crust, spreading it out evenly. Bake the pie in the preheated oven for 35-40 minutes, or until the filling is set and the top is golden brown.
Remove the pie from the oven and allow it to cool for 10-15 minutes before slicing and serving. Garnish with additional fresh thyme leaves, if desired. Enjoy!
