Calories Per Serving


  • 6 large sweet onions, chopped
  • 1/2 Cup flour
  • 1 pie crust
  • 1 stick unsalted butter
  • 2 eggs
  • 1 Cup Parmesan or Gruyère cheese
  • Salt and pepper to taste
  • 2 Tablespoons fresh chives, chopped


Heat the oven to 350 degrees F.

Melt the butter in a skillet on low heat.

Add the chopped onions and saute until they become almost caramelized.

You can cook onions on low heat this way for up to an hour, but if you aren’t that patient, just cook until the onions are translucent and slightly browned.

Remove from heat.

Pour the onion mixture into a mixing bowl, allowing to cool completely.

Put the pie crust in the oven to brown and preheat (about 10 minutes).

In another serving bowl, whisk the eggs.

Stir in the 3/4 cup of the cheese, flour, salt and pepper.

Pour this mixture over the cool onions.


Pour this mixture into the warm pie crust and bake at 350 degrees for 30 minutes.

Pull out the pie and add the remaining 1/4 cup of cheese on the top.

Put back in the oven for another 10-15 minutes.

Let the pie cool for 5 minutes before serving.

Sprinkle the top with chives before serving.
