how to make Ham, Gruyere, and Caramelized Onion Galette with a Fried Egg

Follow the ingredients and directions below. Work step by step and keep the butter and beer cold for the best crust.

Ingredients :

  • 2/3 cup rye flour
  • 1 1/2 cup all-purpose flour
  • 1 teaspoon fine grain sea salt
  • 1 cup unsalted butter, cold and cut into chunks
  • up to 2/3 cup dark beer, cold
  • 1 medium or large onion, sliced
  • Salt and pepper, to season and sprinkle
  • 1 tablespoon balsamic vinegar
  • 1 tablespoon grainy mustard
  • 3/4 cup Gruyere, shredded
  • 1/2 cup ham steak, diced
  • splash olive oil
  • 1 tablespoon butter
  • 1 large egg

Directions :

For the crust: In a large bowl, whisk together the flours and salt. Cut in the butter until it resembles cornmeal and peas. Make a well in the center, pour in beer, and mix until dough forms. Chill for 30 minutes. For the filling: Preheat oven to 375°F. Cook onions in olive oil until translucent, season, and caramelize. Whisk balsamic vinegar and mustard in a bowl. Roll out the dough and transfer to a cookie sheet. Brush with mustard-vinegar, layer cheese, ham, and onions. Fold edges over filling, brush with olive oil, and sprinkle with salt and pepper. Cover with foil and bake for 35-50 minutes until crust is browned. Fry an egg sunny-side up. Top galette with egg and serve.

Serve the galette warm on a plate. Slide the fried egg on top so the yolk runs over the filling. Cut into wedges and eat with a fork. A simple green salad on the side works well.

FAQs

Q: Can I use a different flour?
