  3. 3

    Beat eggs in a bowl until frothy and pour into the skillet.

Tips

Tip 1

Lift the cooked edges gently with a spatula as the frittata cooks to help uncooked egg flow to the pan bottom for even cooking.

Tip 2

Thaw frozen broccoli ahead of time to avoid excess moisture in the finished dish.

Good to Know

Storage

Cover and refrigerate up to 3 days. Reheat in a 350F oven or microwave.

Make Ahead

Common Mistakes

Watch

Do not skip lifting the edges during initial cooking to avoid a rubbery top.

Watch

Do not omit the cover step; it ensures even cooking without flipping.

Watch

Do not add cheese until the eggs are almost set to prevent it from scattering.
