Potato & Red Onion Frittata

Frittata is an Italian classic perfect for any meal of the day, even a special-occasion brunch. Here, market-fresh red onions and potatoes take center stage. —Maria Regakis, Somerville, Massachusetts

    This was a great recipe! Mine took longer for the eggs to set, but it was worth it. I used regular onion, regular potatoes (salted and peppered) cooked in oil, white sharp cheddar cheese, and 1/4 tsp of rosemary. I added some chopped ham when I put that potatoes in towards the end of cooking and it added great flavor.

    One of my favorite frittatas. I substituted shallots for the red onion for a milder flavor. Delicious!

    this was wonderful! i made it a classic frittata and it came out beautifully. i included about 6 strips bacon that needed eating and next time i might include more veggies like peppers, mushrooms,corn or peas. also i will do this as written just to see the difference.

    Only change is put both onions and potatoes on the bottom. It forms a nice sturdy base.

    This was pretty good. I do wish it was not as greasy time I will use a bit of canola oil or cooking spray instead of ALL THAT BUTTER. I made this out of the "best loved recipes" cookbook. I think this would be a 4 or 5 star recipe to me w/out all that butter.

    Good! Added some chopped cooked bacon as well as some other veggies that I needed to use in the fridge (broccoli & red pepper). Turned out great!

    The recipe and ingredients work well together but to make it an authentic frittata you should layer the onion and potato - or any fillings - in the pan and then pour the egg mix over and cook like that. Frittata and a Spanish Omelette are pretty much the same in that respect and this recipe is very similar to a traditional Catalan Spanish Omelette. It's no biggie, it tastes the same either way! It just cuts and serves better. Bon Appetit however you eat it!
