    Just finished dinner. Easy to make, easy to clean up. Tastes great! I made it with 3/4 sprinkled with blue cheese and 1/4 sprinkled with shredded pizza cheese for my oldest daughter who doesn't like blue. I also didn't have fresh thyme, and powdered was too strong. Next time I'll try it in a casserole dish and bake it.

    Thanks again Kittencal. Appreciated the flavours, but to score higher we would've caramelised the onion, then added the cooked potato to the pan and browned it off a bit more to add extra flavour. Also maybe tossed the two together to distribute the flavours more. If cardiologically cleared we would have also doubled the blue cheese - darned artery calcification!

    This was excellent!!!! When doing low carb for breakfast every day it sometimes gets boring but this keeps your taste buds hopping. I cook the onions a bit then but them in the bottom of a casserole dish along with the potatoes then pour the egg mixture over everything and sprinkle w/ blue cheese ( I use more) and thyme then just bake at 350 until a inserted knife comes clean. Easy Easy Easy

    Kitten, you have done it again. This is a delicious frittata. I had a left over baked potato that I peeled and cubed for this dish. Also, when getting out the cheese, I discovered that I did not have blue cheese so I used feta. I think this would be delicious with some fresh dill as a change of pace.

    This was so good & I'm so happy to be the 1st to review it. I admit I was intimidated since I'd never made a frittata before, but the directions were twissis-proof & I think the "bare bones" of the recipe can be used to make many variations. My hubby loved it too & that's always my guage for a keeper. Thx!
