Equipment

  • 1 Medium Skillet - for sautéing the veggies
  • 1 Medium Mixing Bowl - for whisking the eggs
  • 1 9-inch deep dish pie pan (9x2-inch or equivalent) - for baking the no crust quiche

Ingredients

  • 1 TBS Unsalted Butter - or Extra Virgin Olive Oil
  • 1 small Sweet Onion – small dice (about 1 3/4 cup)
  • 2 cloves Garlic – minced
  • 1/4 scant tsp EACH: Crushed Red Pepper Flakes & Ground Nutmeg
  • 10 ounces Chopped Frozen Spinach – thawed, drained & squeezed dry (can substitute 1 ½ cups Fresh Spinach)
  • 12-16 ounces Cooked Bacon – chopped (about 1 ½ cups) (SEE NOTES)
  • 1 ¼ Cup Shredded White Cheddar - DIVIDED (4 ounces)
  • 1 Cup Shredded Gruyere - DIVIDED (3 ounces)
  • 5 large Eggs
  • ¾ Cup Half-and-Half (substitutes: Heavy Cream or Full-Fat Whole Milk)
  • 1 heaping tsp Dijon Mustard
  • To Taste Kosher Salt & Ground Black Pepper

Instructions

  • Preheat oven and Prepare Pan: Arrange oven rack to the middle position and then preheat the oven to 350 degrees Fahrenheit.
    Lightly grease a 9-inch pie pan (9x2-inch or equivalent) with non-stick cooking spray.
  • Saute Onions with Seasonings: Melt the butter in a skillet over medium-high heat. Once the butter is melted, add the diced onions and cook, stirring occasionally, until they're slightly golden and softened, about 5-6 minutes.
    Add the garlic, red pepper flakes, and nutmeg to the skillet and season with a scant 1/4 teaspoon salt and 1/8 teaspoon pepper. Cook the veggie mixture, stirring constantly, for 30 seconds, or until the garlic is fragrant.
    Immediately remove the pan from the heat.
  • Add Spinach and Bacon to Onions: To the skillet with the onions, add the spinach and the bacon, then stir everything to combine the filling ingredients.
  • Add Quiche Fillings to Pie Pan: Transfer the spinach mixture to the prepared pie pan.
    Add 1 cup of cheddar cheese and ¾ cup of gruyere to the pie pan and stir the ingredients to combine.
    Then, use a spatula or the back of a spoon to spread the filling out in an even layer.
  • Prepare the Egg Custard: To a medium mixing bowl, add the eggs, half-and-half, and mustard mustard. Season with ¼ teaspoon salt and 1/8 teaspoon pepper. Then use a whisk and stir the ingredients until thoroughly combined and homogenous.
  • Pour Egg Custard over Spinach Mixture and Top with More Cheese: Pour the egg custard over the spinach and bacon mixture in the prepared pie pan. Next, use a spatula or spoon to gently press the filling ingredients down into the eggs.
    Sprinkle the remaining ¼ cup of EACH cheese evenly over the quiche.
  • Bake Crustless Quiche: Transfer the quiche to the preheated oven and bake for 50-60 minutes, or until eggs are just set. Check for doneness by inserting a toothpick into the filling – it should come out clean.
    (Note: If the top browns before the quiche is done baking, lightly tent the top of the dish with aluminum foil.)
  • Cool Slight, Then Serve No Crust Spinach Quiche: Remove the quiche from the oven and place on a wire rack. Let the crustless quiche cool on the counter for 10 minutes. Then use a sharp knife to slice the spinach quiche into individual servings. Garnish with fresh herbs and enjoy!

Notes

  1. To easily and evenly cook bacon: Arrange oven rack to the middle shelf position. Preheat oven to 425 degrees Fahrenheit (or 400 degrees convection setting if you have it). Arrange bacon in an even layer on a wire rack lined baking sheet. Bake for 12-18 minutes or until cooked and crispy. (No need to flip bacon! If you are not using a convection oven, you may want to rotate the pan halfway through cooking if your oven has hot spots.)
