FAQs

How do I prevent the eggs from overflowing in the microwave?

Use a large enough mug (at least 12 oz capacity) to allow space for the eggs to rise as they cook.

Can I use egg whites instead of whole eggs?

Yes, you can substitute the whole eggs with 4 tablespoons of egg whites for a lower-fat version.

Is it safe to cook eggs in the microwave?

Absolutely. As long as the mug is microwave-safe and the eggs are fully cooked, it’s a safe and efficient method.

What type of mug should I use?

Use a microwave-safe ceramic or glass mug with a capacity of at least 12 oz to avoid spillage.

Can I make this recipe vegan?

Yes, use a vegan egg substitute, plant-based milk, and vegan cheese to adapt it for a plant-based diet.

How do I know when the omelet is done?

The eggs should be firm and no longer liquid. If needed, cook in additional 10-second intervals until set.

Can I double the recipe?
