Tonight I had some different colored peppers and some left over onions from my bag of omelet fixins' I keep on hand.
For my fritata I used 8 eggs, peppers, onions, shredded cheddar, salt & pepper, and some hot sauce (the green kind) for a little added flavor.
Preheat your oven to 400* degrees. In a bowl, scramble the eggs, then adding whatever extras and seasonings you like. Lightly oil a cast iron pan (or whatever pan you have that can go in the oven). Preheat your pan for 2 minutes on the stove top, just under medium heat. Once heated, pour your egg mixture directly into your pan. On your stove top, you are going to cook the eggs for a few minutes until the edges start to set; they will look puffy. I believe I cooked mine for about 5 minutes, making sure I checked every so often.
After my eggs have set, I sprinkled more cheddar cheese on top. Remove pan from the burner and place in oven on center rack and bake for 7 - 10 minutes. I check mine at 5 minutes, and then every 2 minutes. It doesn't take long for it to finish cooking and brown on top.
After removing the fritata, allow to sit for 3-5 minutes to finish setting. I served this fritata with my homemade biscuits. You can find that recipe HERE!
