From a flavor standpoint, ketchup’s sweetness, acidity, and umami can complement eggs, which is why so many people enjoy the combination. Others prefer to let the eggs’ natural flavor shine without any sweet tomato notes.

In the end, it’s a matter of personal taste rather than a rule of cooking.

The Final Verdict

Calling ketchup on eggs an “absolute crime” is all part of the fun. Breakfast is one of the most personal meals of the day, and everyone has their own favorite way to enjoy it.

If you love fluffy scrambled eggs with nothing but butter, salt, and pepper, that’s a classic choice.

If you can’t imagine breakfast without a generous squeeze of ketchup, you’re in good company.

The best breakfast isn’t about following someone else’s rules—it’s about enjoying the food that’s on your plate.
