Tarte á l'Oignon (Savory French Onion Tart)
Cuisine: French Alsatian

Delicious, simple and impressive dish to serve next time you host!
  • 4-5 large onions, roughly chopped
  • 1-2 tbs. unsalted butter
  • salt, pepper
  • ½ tsp. nutmeg
  • 2 slices ham or prociutto, roughly chopped
  • 1 tbs. all-purpose flour
  • 1 egg
  • ½ cup milk
  • 1 cup emmentaler, grated (could sub in some gruyere or swiss or other cheeses)
  1. Have savory dough ready - I like to have it rolled out on my pan then I keep it cold in the fridge til I'm ready. I have an awesome flaky savory dough recipe in my Tarte á la Tomate post.
  2. Preheat oven to 450
  3. Heat butter over low-medium flame
  4. Add onions, stir and cover to sweat
  5. This is a good time to grate cheese, roughly chop ham or prociutto
  6. Add ham or prociutto to sweated onions
  7. Add flour
  8. In a separate bowl, whisk egg and milk together
  9. Turn off flame, add mixture to onions
  10. Pull out your prepped dough, pour in onions
  11. Generously sprinkle grated cheese on top
  12. Bake at 450 for 20 mins, then reduce heat to 350 for another 20 mins, cheese and edges of crust should be golden brown
  13. Let cool for 10 mins on cooling rack before digging in
  14. Enjoy!
