I served this crustless quiche at a church lunch, and I had to laugh when one guy told me how much he disliked vegetables. Many people were surprised by how much they loved this veggie-filled quiche recipe—and he was one of them! —Melinda Calverley, Janesville, Wisconsin


  • 1 cup chopped onion
  • 1 cup sliced fresh mushrooms
  • 1 tablespoon canola oil
  • 1 package (10 ounces) frozen chopped spinach, thawed and well drained
  • 2/3 cup finely chopped fully cooked ham
  • 5 large eggs
  • 3 cups shredded Muenster or Monterey Jack cheese
  • 1/8 teaspoon pepper


  1. In a large skillet, saute onion and mushrooms in oil until tender. Add spinach and ham; cook and stir until the excess moisture is evaporated. Cool slightly. Beat eggs; add cheese and mix well. Stir in spinach mixture and pepper; blend well. Spread evenly into a greased 9-in. pie plate or quiche dish. Bake at 350° for 40-45 minutes or until a knife inserted in center comes out clean.

Crustless Quiche Recipe Tips

Is a frittata the same as a crustless quiche?

The difference between a frittata and a crustless quiche comes down to the ingredients. Fritatta recipes typically call for eggs and very little additional dairy, while quiche recipes (whether crustless or with a crust) usually include milk, cream or half-and-half in addition to eggs. As a result, frittatas are often more like an omelet in texture while quiches are more like a savory, creamy egg pie. The two are also baked in different pans: frittatas are often baked in an oven-safe skillet, quiches in a pie pan.

Why is my crustless quiche watery?

Crustless quiche "comes together" in the oven as the egg proteins bind from the heat, but this process also squeezes out water. The key to preventing a soggy quiche is to cook it slowly and possibly remove it from the oven early—while the center is still a touch wobbly—so that residual heat can finish the cooking. Also make sure to cook out, dry or remove any excess moisture from your mix-ins (such as vegetables and meats), which could also contribute to a soggy quiche.

How do you keep a crustless quiche from sticking?

Generously grease the pie plate you are cooking your crustless quiche in to ensure an easy release and minimal sticking. A good cooking spray or healthy slathering of butter should do the trick!

Can you freeze a crustless quiche?

Yes! After baking, allow your crustless quiche to cool completely. Wrap the quiche tightly in plastic wrap, followed by foil, then freeze it for up to 3 months. To reheat, unwrap the quiche, place it back in the pie plate, and heat it in the oven until thawed and completely heated through.
