Ingredients
  

Pastry Crust

  • 1 stick cold unsalted butter
  • 1 Cup all-purpose flour
  • ¼ tbsp salt
  • 4 tbsp cold water (I drop an ice cube in to ensure the "cold"ness)

Tart Filling

  • 4 medium onions, sliced
  • butter/olive oil
  • 6 eggs
  • cup whole milk
  • 1 tbsp salt
  • pepper
  • ½ tbsp nutmeg
  • 3-4 sprigs fresh thyme or 1⁄2 teaspoon dried thyme (I only had dried on hand -- make sure to rub it between your fingers so the flavor wakes up)
  • 2 cups shredded cheddar cheese

Instructions
 

  • Cube the stick of butter and add to food processor (I miss using my hands to warm up the cold butter cubes,but I admit this way is very quick! If not using a processor, add the cubes to a mixing bowl.) Add flour and salt, and pulse about 12 times. Add cold water and pulse until the texture looks like sand.
  • Empty out onto a flat counter surface and gently knead just a little bit to incorporate the ingredients, but don't over knead. Roll into a ball, press into a disc and wrap in cling film.Refrigerate for 15-30 minutes.
  • Once chilled, roll the dough with a floured rolling pin onto a floured surface, making sure to flip over occasionally to prevent sticking until the circle is at least 1-2 inches larger than the diameter of your tart pan.
  • Lay the dough over the tart pan (I like to butter the tart pan for extra anti-stick protection and buttery-ness of course), pressing into the ridges with a small piece of excess dough. Trim off the tops of the ridges/pan with a knife, making sure to slice away from you.
  • Prick the bottom of the tart pan dough all over with a fork. Refrigerate for 2 hours or freeze (I froze overnight in order to make for breakfast.) Note: my overnight frozen tart receded a bit from the top of the shell.
  • Preheat oven to 400ºF. Fill the tart shell with beans after placing a piece of parchment paper into the shell. Blind bake for 15 minutes. Remove the beans and continue to bake for another 5-10 minutes, until the bottom is dry and lightly golden brown.
  • Saute the sliced onions over medium heat into a couple tablespoons of olive oil and (Kerry Irish) butter. Stir continuously for 30 minutes or more until they caramelize to your liking.
  • Whisk the eggs & milk, salt, pepper, nutmeg and thyme. Add in the cooled onions.
  • Add in 3/4 of the shredded cheese. Pour into tart pan, making sure to have pan set onto a baking sheet. (Make sure to discard any scrambled egg extras that arise from an overfilled base!)
  • Bake for 35-40 minutes (lower to 375 degrees if browning too quickly.) Let sit 5-10 minutes before serving. Enjoy whatever combination of cheese, egg, and onion you have. This is a simple, yet rich recipe. Add in any additional flavors,like sausage, ham, bacon, tomato, olives, zucchini. The tart's the limit.
