Tips

Tip 1

Make sure vegetables are translucent but not browned for the best texture and flavor distribution throughout the omelet.

Tip 2

Let the baked omelet rest for a few minutes after removing from oven to allow eggs to finish setting and make slicing easier.

Tip 3

Test doneness by gently shaking the pan - the center should be just set with no liquid egg visible.
