Spinach and Gruyere Crustless Quiche

A slice of crustless quiche with spinach

There is a common misconception that a quiche needs a heavy, buttery crust to be satisfying. For years, I spent hours chilling dough and blind-baking crusts, only to find that the filling was what everyone actually cared about. This Spinach and Gruyere Crustless Quiche is my answer to a faster, lighter, and arguably more delicious brunch staple. By removing the crust, you let the silky custard and the nutty, sophisticated flavor of Gruyere cheese take center stage. It’s a versatile dish that works just as well for a fancy Sunday morning as it does for a quick Tuesday night dinner. The texture is incredibly light and almost soufflé-like, making it a favorite for anyone looking for a low-carb but high-flavor meal.

Ingredients

  • 6 large Eggs: Preferably pasture-raised for a richer yolk.
  • 1 1/2 cups Half-and-Half: For a creamy but not too heavy custard.
  • 1 1/2 cups grated Gruyere Cheese: Swiss or sharp cheddar can be substituted.
  • 1 bag (10 oz) fresh Spinach: Chopped and sautéed.
  • 1 small Shallot: Finely minced.
  • 1 tbsp unsalted Butter: For sautéing and greasing the dish.
  • 1/2 tsp Salt: To enhance the savory notes.
  • 1/4 tsp black pepper: Freshly ground.
  • 1/8 tsp ground Nutmeg: The secret ingredient for any egg dish.
  • Fresh Chives: For garnish.

Step-by-Step Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C). Generously grease a 9-inch pie dish or quiche pan with butter.
  2. Sauté the Spinach and Shallot: Melt 1 tablespoon of butter in a large skillet over medium heat. Add the shallot and sauté for 2-3 minutes until soft. Add the chopped spinach and cook until just wilted.
  3. Drain Excess Moisture: This is the most important step! Place the sautéed spinach in a fine-mesh sieve or use clean paper towels to squeeze out as much water as possible. Extra moisture will make the quiche soggy.
  4. Whisk the Custard: In a large bowl, whisk together the eggs, half-and-half, salt, pepper, and nutmeg until completely smooth and slightly frothy.
  5. Layer the Filling: Evenly spread the drained spinach and shallot mixture over the bottom of the greased pie dish. Sprinkle the grated Gruyere cheese over the top.
  6. Add the Custard: Carefully pour the egg mixture over the spinach and cheese. Use a fork to gently move the ingredients around so the custard fills all the gaps.
  7. Bake: Place the dish in the oven and bake for 35-40 minutes. The quiche is done when the edges are golden brown and the center is set but still has a very slight jiggle.
  8. Cool and Set: Let the quiche cool for at least 10-15 minutes before slicing. This allows the custard to fully set for perfect, clean slices.

Tips

  • Squeeze the Spinach: I cannot stress this enough! Fresh spinach holds an incredible amount of water. If you don't squeeze it dry, that water will leak into your quiche during baking.
  • Use Quality Cheese: Gruyere is classic for a reason—it melts beautifully and has a complex, nutty flavor. If you can't find it, a good quality aged Swiss or even Comté is a great substitute.
  • The Nutmeg Secret: Just a tiny pinch of nutmeg doesn't make the dish taste like spice; instead, it deepens the savory flavor of the eggs and cream.

FAQ

Yes! Use about 1 cup of frozen chopped spinach. Thaw it completely and squeeze it extremely dry before adding it to the quiche.

Insert a knife or toothpick into the center. If it comes out clean, it's done. The top should also be slightly puffed and a beautiful light golden color.

Yes, it freezes quite well. Wrap individual slices tightly in plastic wrap and then foil. Reheat in the oven or air fryer for the best results; the microwave can make it a bit rubbery.
