  1. Preheat oven to 350 degrees F (175 degrees C). Grease an 8x8-inch baking dish.
  2. Heat butter and olive oil in a skillet over medium-high heat; cook and stir onion in the heated butter-olive oil until onions soften, 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 8x8-inch 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®!
  • Tip
  • Aluminum foil helps keep food moist, ensures it cooks evenly, keeps leftovers fresh, and makes clean-up easy.

I read the Cook's Notes, and decided to give this a sprinkle of paprika to give the top of the quiche a little more color (that worked beautifully). I sprayed the dish liberally with cooking sp...

Loved this recipe. Modified it slightly for what I had on hand. Substituted sharp cheddar for the mozzarella and put in closer to a cup. Also added a sliced tomato before baking and when cooking...

Really love the flavor of this! I made this exactly as written, except that I used a 10-in ceramic quiche pan. I took it out of the oven just shy of 35 mins, and it was puffy and beautiful. It d...

Loved this recipe! I didn't have heavy whipping cream so I used 1 cup of milk with 2 heaping spoonfuls of cornstarch. I added (mooshed in) about 2 oz of light cream cheese. Sprinkled with som...

This was so easy and delicious! I doubled the eggs but kept the milk, cheese and everything else the same. I caramelized the onion in an iron skillet. Then poured egg mix into skillet and bak...

This is superb. I made it twice. Couldn't get enough the first time.! I made no changes. If you invite some friends to come to lunch, serve this with a salad, iced tea and crusty bread and ...

Very tasty, added ground beef and garlic powder because we had it for dinner (with salad and rolls). I used whole milk and 4 oz of cream cheese instead of cream and mild cheddar cheese, both bec...
