Onion Bread Frittata Ingredients

Onions – red onions are sweeter than white onions and lend a wonderful flavor to the frittata.

Eggs – the eggs form the base of the frittata.

Cheese – use mature cheddar for added flavor.

Seasoning – salt and dried parsley are used, but you can also use other dried herbs.

Tips

For a lighter frittata, add a bit of milk or water to the eggs.

If you want the onions to taste sweeter, you can caramelize them beforehand.

To caramelize onions, heat 2 tbsp olive in a large pan over medium heat. Add 3 red onions (sliced), and a pinch of salt, and cook for about 40 minutes. Stir the onions every now and then to prevent the onions from catching on the bottom. Add 2 tbsp balsamic vinegar and 2 tbsp brown sugar and continue to cook for 5 minutes.
