Servings: 8 slices
Calories: 232kcal

Ingredients

  • 2 Tbsp butter
  • 2 medium yellow onions thinly sliced
  • 6 eggs
  • 1 tsp dried thyme or 1/2 tsp fresh
  • 1 tsp salt
  • 1/4 tsp nutmeg
  • 1/4 tsp pepper
  • 1 C Gruyere cheese shredded
  • 1 C heavy cream or whole milk

Optional Toppings

  • arugula
  • sour cream watered down with 1 tsp water

Instructions

  • Heat a large skillet over medium heat, melt butter and add onions.
  • Heat oven to 350°F. Spray pie dish with non stick spray. Set aside.
  • Caramelize onions by stirring every few minutes. If they start burning, turn down the heat and stir more often. Keep cooking until soft and golden. About 20 minutes.
  • In a medium bowl, whisk eggs, spices, 1/2 the cheese and heavy cream.
  • Place onions in the bottom of the pie dish. Pour egg mixture on top.
  • Add remaining cheese around the outer edge of the pie dish. If you put it in the middle, it'll keep the quiche from rising in the center.
  • Bake on center rack for 30-35 minutes or until center is just set.
  • Allow to cool 5 minutes, then dish and serve. Top it off with fresh arugula and watered down sour cream (so it drizzles, rather than dollops).

Notes

Great for lunch or dinner too!
