Prep Time: 15 mins
Cook Time: 45 mins
Total Time: 1 hr
Servings: 8

Ingredients

  1. 1 tablespoon butter
  2. 2 teaspoons olive oil
  3. 1 small onion, diced
  4. ¾ cup heavy whipping cream
  5. 3 eggs
  6. salt and ground black pepper to taste
  7. ¾ cup shredded mozzarella cheese
  8. ¼ cup grated Parmesan cheese

Instructions

  1. Preheat the oven to 350 degrees F (175 degrees C). Grease an 8-inch square baking dish or pie pan.
  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. It should be light brown around the edges but not brown on top.
  5. This doesn’t rise very much, so if it looks flat, it’s normal.
  6. It will be hard to get out of the pan even if sprayed with Pam!
  7. 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.

This was super yummy! I followed the recipe exactly (using a pie pan). But I did add mushrooms from a jar. I just added the mushrooms to the onions and sautéed them together.
Scott Chavez
Absolutely delicious. I made in an 8×8 pan, increased eggs to 5, and used mozzarella and a combo gruyere/white cheddar. Used canola oil pan spray and a light dusting of flour. Had no problems with sticking. Garnished with more caramelized onions and chopped parsley. Loved by all! Easy to make, but the caramelized onions and variety of cheeses really make it an impressive dish.

I made this using what I had on hand due to Covid 19. Used a mix of leeks and onions, Used half and half instead of cream. I added left over zucchini and some sun dried tomatoes. We had this for lunch and really liked it. You could add other veggies such as spinach, asparagus or mushrooms. Will make this again

I made this last night for dinner during our stay-at-home order here in Los Angeles. Since we are not going out or even visiting the grocery store until supplies are very low, I made a few modifications using what we had in the pantry and fridge and it was wonderful! Caramelized onions makes every recipe special! Modifications included: 5 eggs, jack cheese and added sautéed zucchini, corn and a few strips of bacon. We are running low on milk so I used Rice Dream, vanilla flavored. This crustless quiche came out slightly sweet (Rice Dream) and hubby loved it! I served small portions and offered him more but he declined stating he wanted to enjoy it again at another meal! This is a great recipe that’s versatile based on what’s available in the fridge and pantry.

Simple & delicious! Can’t wait to try it with additional veggies and/or meats and with a variety of cheeses! Definitely going to become a weekly staple.

increased eggs to 6 and onions to 4 and added some fresh spinach – delish

Deliciously rich, irresistibly moist, this quiche is a showstopper. I followed the recipe exactly except for three changes, I thought that putting honey ham in it would bump up the flavor and would go very well with the cartelized onions, I was right, it was delectable. I also substituted the heavy whipping cream with half in half and it still turned out perfect. I also used Monterey Jack cheese instead of mozzarella and had no problems with it. Served it for lunch and the fam loved it. I will definitely make this again.

This is absolutely fabulous, delicious, and best of all very easy to do. My recommendation would be to use Wilton’s Bake Easy! and bake it in a ceramic or glass pan. Mine came out fluffy and did not stick to my Le Cruiset ceramic pan. This not only makes for an easy breakfast but also an easy dinner with crusty bread or cherry tomatoes on the side!
Hector Matthews
I added browned chorizo, and some extra mozzarella cheese and one extra egg…wonderful!

This recipe has become a staple in our house. Very easy and tastes great. Lots of variations are possible as well. I add broccoli and sometimes turkey bacon, cooked crisp first then chopped up and put in the quiche. To lower calories I use egg substitute (Egg Beaters) and 1% milk. The texture still comes out great. Thank you!
Deborah Sellers
I adapted this for fresh veggies I had on hand. It was excellent! i will keep this one for sure.
Lindsay Hill
Very tasty! You can use this as a base and do a lot with it , but it is also great as is. I doubled the recipe as is for six people at breakfast and there was about one helping left. We also had toast and a coffee cake.
Antonio Tran
It turned out SO GOOD!!! I would make this every morning if I could. It was really easy to make and SO flavorful. I used sautéed mushrooms in addition to the onions and asiago cheese instead of mozzarella. Definitely going to be my go to breakfast to make for company from now on.
Jason Moore Jr.
Loved it. Perfect for 2. Added chopped peppers. So easy. Will definitely make again. Next time will try adding some tomato slices, maybe some spinach.
Vincent Rivas
I doubled the recipe and followed it exactly except I added some baby spinach and kale from my garden . I used the pan I had the onion in that was still hot and dropped in the chopped greens and let then just sit there until it was time to add to the eggs and cream. I cooked mine in a ceramic quiche dish and it was finished in about 37 minutes. Everything about this quiche is perfect. I am only using this recipe from now on with or without a crust. It had a beautiful texture and I think you could use it as a basis for many ingredients. So easy , so yummy!
Katherine Davies
Very tasty! I used a glass pie plate and cooking spray and had no sticking issues. I added some ground nutmeg for a little more flavor and served with light salad. Easy. I will make it again.
Marie Horton
I made this recipe but with crust. It was outstanding. I was specifically looking for breakfast recipes that I could make in large batches ahead and freeze in individual containers. I work full time and am taking classes in the evening, the last thing I want to do during the week is cook. So, my review covers both the fresh from the oven and the pulled from freezer and thrown in the microwave at work. Outstanding both times.
Hannah Smith
I made it per the recipe with one exception…I didn’t have mozzarella cheese (thought I did) so ended up making it with colby jack. It was delicious and I will definitely make it again. I want to make it next time with the mozzarella…I bet it will be even better.
Andrew Wagner
Easy, tasty, great for brunch. Make two if you are entertaining more than four people. 45 minutes but it was burned on the bottom, start checking at 35 minutes. I used a little sugar on the onions and it made a satisfying coffee brown (too crispy) crust. I think it is a very good recipe. 5 stars for ease!
Mr. Michael Mclaughlin
delish and easy, grant like it a lot. Made in a glass pie pan
Phillip Bell
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 baked in oven for 35 min. It was perfect and husband loves! I will definitely make this again.
