This easy crustless quiche is always a hit with the family. It's vegetarian but satisfying for those meat-eaters too. Good for breakfast or any meal paired with soup and salad. It's great as leftovers too.

A good way to use up a sweet potato which is definitely healthier than a regular potato. I too used a whole medium sweet potato. My grandson (8 yr. old) said they tasted like carrots. He did eat his whole serving. If you want more of a crust on your quiche add 1/4 cup of flour to your egg mixture. Because I often add Tabasco sauce on my cooked scrambled eggs or omelette I added hot sauce on top of my serving. I would make this again if I wanted a sweet potato for my meal. I would not buy a sweet potato so I could make this though. Read More

Used onions in place of leeks. Added some leftover diced ham for my meat loving family and it filled their bellies for brunch with a salad & soup. Read More

Great recipe. I made a simple crust under the quiche and the whole dish came out amazing. Didn't use leak (didn't have any) needs more salt than the recipe calls for. Used a whole sweet potato and boiled it in hot water before putting it In the frying pan. Used a different cheese on top. Definately will make again:) Read More

excellent tastes, I did add some fresh rosemary, and i just used the cheese that I had in my frig. It tastes fabulous, however, Next time I will be sure to have the cheese it calls for, I did not have any sour cream so I omitted that and added an additional 1/4 cup of 1/2 & 1/2 cream. Consistency still good. Read More

It was flippin' gorgeous coming out of the oven and the flavor was wonderful but even though I served it with rice I missed the crust to hold it all together. Also I had more than enough ingredients for my 9" pie plate. Read More

This was very good. After reading the other reviews I used a whole sweet potato. Also added spinach and used fat free 1/2 & 1/2 instead of the cream. I put it in a crust just because I like having crust on a quiche but it baked up nicely and would be fine without one. Read More

I added three extra sweet potatoes (consulting another recipe) to get rid of extra sweet potatoes I had in the fridge. Because there was a lot of potato to cook I cooked them in the microwave (again due to the other recipe - stick holes in each with fork and microwave in about one half inch of water for about 12 mins) then cut them up and added them to the onion mixture. It makes a very sweet quiche but still very good. I also used just whatever shredded cheese I had in the fridge (Mexican four cheese blend) for the topping. Read More
