This pie is nothing less than delicious…. The combination of the crisp pie dough and the perfectly seasoned creamy caramelized onions is indescribably good!! It is so good that we eat almost all of it alone and went to bed with a terrible stomach pain!

It is definitely one of those recipes which we will make again and again and again…….. Maybe we’ll even have as a side dish for Thanksgiving together with turkey, mashed potatoes and gravy 🙂

 

Ingredients (6 servings)

Pie Dough

2 2/5 cup flour

2/3 cup butter, cold

2 small eggs, beaten

1/2 tsp. salt

1/2 lemon, juice

1 egg, beaten (for brushing)

 

Caramelized Onions

5 large onion, sliced

2 tbsp. fresh thyme leaves

3 tbsp. butter

2 tbsp. flour

1/2 cup apple juice

1 cup cream

1/2 cup Gruyere cheese, shredded

 

Pie dough: Cut the butter in to small cubes and place it in a mixing bowl together with flour and salt. Use an electric hand mixer or stand mixer to mix until it looks like breadcrumbs.
Add the two beaten eggs and the lemon juice and mix until just combined. Pour the combined dough on to slightly floured surface and knead for a few minutes. Make sure that there are no lumps in the dough – it should be smooth. Wrap in plastic foil and fridge while making the caramelized onions.

 

Caramelized onions: Melt the butter in a sauce pan at medium heat and add onion slices and thyme leaves. Stir once in a while until onions begins to get soft and stick to the bottom of the pan. This takes about 15-20 minutes at medium/low heat. Then add about half of the apple juice and let simmer until evaporated before adding the other half of the apple juice.
Sprinkle the flour on top of the caramelized onions when the remaining apple juice has evaporated and stir to combined. Then slowly pour the cream into the onions while stirring to combine. Let simmer for a further 3-5 minutes before tasting and seasoning with salt and pepper. Set a side while rolling out the pie dough.

Cut the pie dough into two pieces – 2/3 and 1/3. Roll the largest piece out until it is large enough to cover a the bottom and sides of a 9 inch pie dish. Place the rolled dough in a greased and floured pie dish. Pour the caramelized onions into the pie and sprinkle with the shredded gruyere cheese. Grease the edges with beaten egg.
Roll out the remaining dough, cut a few holes in it so any remaining liquids can evaporate, and place on top of the caramelized onions. Press the dough together with your fingers or a fork. Brush the top of the pie with the beaten egg. Bake at 400F for 30-35 minutes and let rest on a wire rack for further 15-20 minutes before serving.

Serve as a side dish for oven roasted chicken or on a larger buffet 🙂
