Total Time:
1 hr


  • 1 tablespoon butter

  • 2 teaspoons olive oil

  • 1 small onion, diced

  • ¾ cup heavy whipping cream

  • 3 eggs

  • salt and ground black pepper to taste

  • ¾ cup shredded mozzarella cheese

  • ¼ cup grated Parmesan cheese


  1. Preheat the oven to 350 degrees F (175 degrees C). Grease an 8-inch square baking dish.

  2. Heat butter and olive oil in a skillet over medium-high heat; add onion. Cook and stir until softened, about 10 minutes; transfer onion to a plate to cool.

  3. Whisk cream, eggs, salt, and black pepper in a bowl; stir in mozzarella cheese, Parmesan cheese, and onion. Pour mixture into the prepared baking dish.

  4. Bake in the preheated oven until eggs are set and a knife inserted in the center comes out clean, about 35 minutes.

Cook's Note:

You can use a pie plate or an 8-inch square pan. Also, your quiche shouldn't be brown on top but maybe a light brown around the edges.

This doesn't rise very much, so if it looks flat — it's normal.

It will be hard to get out of the pan even if sprayed with Pam!

Editor's Note:

Please note the addition of Swiss or Gruyère cheese and spinach, as well as the difference in serving size amount, when using the magazine version of this recipe.
