I made so many changes that I'm not sure it's fair to rate this recipe, but here's my feedback in case it's helpful. To reduce calories/fat, I baked this without a crust. I used 5 eggs as recommended by others. I completely changed the other ingredients--used sauteed mushrooms and spinach, feta cheese, diced kalamata olives, balsamic onions (Barefoot Contessa brand), garlic powder, pepper, paprika, and half 'n half instead of cream. I baked this concoction in a glass pie plate at 350 for 30 minutes. It turned out very well (hubby just devoured it and asked me to make another one). I agree with other reviewers who comment that this is a great base recipe upon which it's easy to build whatever quiche you want. The ratio of eggs to dairy is perfect if you use 5 eggs and 1/2 cup milk/cream. This was a great way to use up ingredients that were in the fridge! Next time I might try using Egg Beaters to reduce the fat further.

I wasn't expecting much from this recipe, but I happened to have most of the ingredients on hand and wanted to use them up. I was pleasantly surprised, this turned out fantastic! Based on the other reviews, I did use the equivalent of 4 eggs (actually, 1 cup of Better N Eggs to lower the fat content) and 3/4 cup reduced fat Swiss cheese. I also cooked 5 strips of Morningstar 'fakin' bacon' and crumbled that up and sprinkled it on top of the onions, which I layered in a whole wheat frozen pie crust (pre-baked for 10 minutes at 450 since I like a crisp crust). Then I poured the egg and cheese mixture over the onions and 'bacon' and baked the whole thing until the top was slightly browned. It turned out delicious, such a versatile recipe. You could add almost any kind of meat or even use fake meat as I did. I do think it wouldn't be nearly as good with just the onions and cheese but would be more like an omelette in a crust. The savoriness of the 'bacon' really made this special. And it's so easy, I always thought quiche was difficult but I whipped this up in just a few minutes! Definitely a keeper.

This is a staple for my recipe book. Its delicious as is and extremely adaptable to whatever you have on hand. I have added bacon, toasted pine nuts, paprika and nutmeg to it with great success.

This was a very good, very basic, very quick quiche that could be easily customized. I pretty made as is except I used half & half instead of cream, and on the recommendation of another member I added another egg. I forgot to get swiss at the store so I used 1/4 c. cheddar & 1/4 c. parmesan. NOTE: If you are using a deep dish pie crust this quiche will not be enough to fill the crust.

This recipe is great. Everyone who tried it loved it. I made it twice and I think you need 4 eggs. I guess it depends on the pie crust you use though. I also used 1/2 cup of cheese. Definitely a keeper!

I loved this receipe it was simple enough for a quick enough for lunch, a light dinner or brunch. I added some cracked pepper, a little salt, nutmeg and some dried italian seasoning. It was hit with my family. I seved it with sauteed brocolini and fresh tomatoes thinly sliced with a few sprinkles of cracked black pepper and lightly salted. It was a hit with my family. I agree with another member would be good smoked salmon or even crab meat.

Very good and simple recipe. I followed some other suggestions and added leeks, instead of onions, and some potato cubes. I used 4 eggs instead of 3. Good recipe...it took only minutes to prepare and 30 to cook!! :)

I thought this recipe would be bland so I played with it a little. I substituted leeks for onion (which I just happened to have leftover from another dish), added some bacon (again leftover), nutmeg (traditional for quiche), garlic and cayenne to the mix and it turned out fantastic! Oh I also topped the quiche with some thinly sliced tomato before baking.

This is an excellent basic quiche. Add smoked salmon, bacon, ham or sausage and some capers for variety. Thanks, Sara.

It was kind of rich - maybe I'm not used to the cream - at least not for breakfast. I will try the recipe again with other ingredients, maybe like ham and cheese.

I'm not really fond of eggs, but I decided I should try something new. I made this and added chicken, mushrooms, and mozarella cheese (along with the onions). It's good with hot sauce and a little sour cream, but it's not something I'd probably ever have a craving for.

Yum!!! I didn't have swiss so I used Cheddar. I also added some crisp baccon. Very tasty for brunch on Sunday morning.

This was lovely. I did have to add an egg (i may have had a larger pie shell, not sure) and I also added a layer of cooked sausage over the onions. I would definitely make this one again!

This was very good. I used extra cheese and added seasoning salt and pepper. This is super easy and yummy, especially for a weekend morning. Thanks!

This is a good basic recipe that can be adjusted according to personal preference. Tonight I made it with a combination of Swiss, extra-sharp Cheddar and Gruyere cheeses, and only needed 2 large eggs, also mixed in a little bit of s&p. Husband isn't a huge quiche fan, but I loved it. Thanks!

Excellent & VERY quick!!!!

This was very good and simple to make. I added green peppers, garlic powder, chicken, sharp cheddar and I topped it off with tomato slices and feta cheese. I will make this again for breakfast but add more breakfast type ingredients.
