Is a frittata the same as a crustless quiche?

Frittatas and crustless quiche are similar. Quiche, which is more of a custard, has more dairy than a frittata. You also start cooking a frittata on the stove in a cast-iron skillet and finish it off in the oven. A quiche bakes in a pie dish in the oven the entire time.

How to Make Crustless Quiche

  • Cook the quiche filling: Sauté the onion and potatoes until they soften, and then add the jalapeño, chili powder, and paprika. Spread the vegetables in an even layer in the pie dish.
  • Prep the eggs: Whisk the eggs, milk, half and half, and salt.
  • Assemble: Pour the egg mixture over the veggies in the pie dish, sprinkle with cheese, and top with jalapeño slices.
  • Bake: Place the dish in the oven and bake for 35 to 40 minutes at 350 degrees.

Can I prep quiche the night before?

Yes, quiche is great for meal prep. You can combine all the ingredients and refrigerate the dish overnight. Whenever you’re ready to serve the quiche, bake according to the instructions.

If you have leftover quiche, refrigerate it for up to four days and reheat in the microwave, it makes a great breakfast or lunch when you’re in a hurry.


  • Add diced ham for extra protein.
  • Swap the jalapeno for bell peppers if you like it mild.
  • If you don’t have 2% milk, you can use whatever you have on hand.
  • If you want a crust on your quiche, use store-bought pie dough.
  • For mini crustless quiche, bake the egg mixture in a muffin tin 350 degrees for 28 to 30 minutes.
