  • 1 c. Cooked brown rice
  • 3/4 c. Cooked bulgar
  • 1/2 tsp. Kosher salt
  • 1/4 tsp. Freshly ground black pepper
  • 1/4 tsp. Paprika
  • 1/4 tsp. Garlic powder
  • 1/2 c. Grated parmesan
  • 1 large Egg white, lightly beaten

Egg Mixture

  • 3 Eggs
  • 3/4 c. Whole milk
  • 2 Tb. Grated parmesan
  • 1/4 tsp. Kosher salt
  • 1/8 tsp. Freshly ground black pepper
  • Pinch Ground nutmeg

Caramelized Onions & Fillings

  • 2 Tb. Olive oil
  • 1 Tb. Unsalted butter
  • 3 large Yellow onions, peeled & thinly sliced
  • 1/2 c. Curly or Tuscan kale, roughly chopped
  • 2-3 slices Crispy bacon, chopped (optional)


  • Heat oven to 375 degrees and spray a 9" pie dish with cooking spray.
  • Add rice, bulgar, salt, pepper, paprika, garlic powder, parmesan and egg white to a bowl and stir well to coat everything with the egg white.
  • Transfer filling to the pie dish. Push and press the filling toward the edges and bottom using your fingers or a small measuring cup. Build up the sides, but press the top of the side crust so it's tightly packed (this will reduce flakiness after it's cooked). Keep an even layer all around, then place it on a baking tray and into the oven 10-12 minutes (until surface is lightly browned). Remove from oven an allow to cool thoroughly.
  • While crust browns, prepare caramelized onions by adding olive oil and butter to a skillet over medium heat. Add onions, a healthy pinch of salt and a few grinds of black pepper. Stir to coat the onions, reduce heat to low, and allow onions to soften 10-15 minutes, covered. Check and stir regularly; if the pan becomes dry, add a few tablespoons of water and keep cooking over low heat until onions are nicely browned.
  • Combine eggs, milk, parmesan, salt, pepper, nutmeg and parmesan in a bowl.
  • Add caramelized onions to the cooled crust, along with chopped kale (and bacon, if using). Slowly (a little bit at a time) pour egg mixture over the onions/kale but be sure to not allow it to breach the sides of the rice crust. Place on a baking sheet and bake 25-35 minutes, until edges are browned and filling is set. Remove and cool 10-15 minutes before serving.


Note: feel free to use your favorite quiche custard/recipe, but I recommend making only half of it because, depending on your fillings (onions, tomatoes, veggies, etc.) you don't want to overfill or breach the sides of the grain crust (which could result in a soft or messy crust while baking).
