  • Ready In

  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(R)!



This was so easy, and so delicious! I made a couple of small changes, and it worked out really well! First, I fried up 2 pieces of bacon, then added the butter and olive oil, as well as about ...

I used this recipe as a base for my veggie quiche and it was excellent. I will use this again. Besides the veggies, what I did change was that I added 1/2 cup of flour and this made it prett...

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...

I liked it a lot, but the texture was not what I expected. I added peppers and mushrooms because I had them and they sounded good; great addition. It was very easy too so I will probably make th...

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...

DELICIOUS!! Added crisp bacon and used sharp cheddar cheese and 4 eggs, use less salt with bacon. Was eaten up next to pancakes. Only had 6 eggs which would have made it enough for the family bu...

Delicious and easy to make. Like several others, I doubled the recipe. Doubled, it serves 2-3 people unless you eat very small portions or you use jumbo-sized eggs. I had half-and-half on ha...
