10: Preheat your oven to 356°F (180°C). Put a non-stick frying pan on medium heat without fat, and then put in a metal ring. If you don't have metal ring, don't worry, use any pan you can find with non-stick bottom (otherwise put a sheet of greaseproof paper in the bottom) which can go both on the hob and in the oven.
11: When frying pan is quite hot, pour in the egg mix and cook like this for about 3 to 5 minutes.
12: Then put in the oven for about 10 minutes, check cooking like for a cake.
13: Don't hesitate to finish under the grill to brown the top.
14: Remove the ring (if used) by passing a knife blade all around it, between omelette and metal sides.
16: A possible variation, tomato souflée omelette: pour half the mixture into pan, then add a layer of cooked tomato slices (pan-fried beforehand in a little olive oil), and finally add the remaining mix. Then cook and serve as usual.
Remarks
The ideal utensil for this recipe is a non-stick frying pan with removable handle. Serve with a herb salad on the side, as I think that something with a hint of acidity makes a good accompaniement.
