This crustless ham and cheese quiche is an easy, gluten-free breakfast or brunch that comes together with simple, everyday ingredients you likely already have on hand. Eggs, cream, savory ham, sautéed onion, and melty Swiss or cheddar cheese are layered into a pie dish and baked until just set and lightly golden.
Preheat the oven to 375°F. Grease a 10-inch cast-iron skillet or 9-inch pie dish with butter or nonstick spray.
In a medium bowl, whisk together eggs, heavy cream, salt, pepper, nutmeg, and 1 tablespoon chopped parsley until smooth. Set aside.
In a skillet over medium-low heat, heat oil and sauté onions until soft and translucent, about 4–5 minutes. Spread the cooked onions evenly over the bottom of the prepared skillet or pan.
Add the diced ham and sprinkle ¾ cup of the cheese evenly on top.
Pour the egg mixture over the onions, ham, and cheese. Top with the remaining cheese.
Bake for 35–40 minutes, or until the center is just set and the top is lightly golden. Let cool for 5–10 minutes before slicing. Garnish with remaining parsley and serve warm.
Notes
Swiss, cheddar, Gruyère, or Monterey Jack all melt well and pair nicely with ham. You can mix two kinds for more flavor.
Cooked bacon, sausage, or even diced turkey make great substitutes. Just ensure they’re fully cooked before adding to the dish.
