About Breakfast On A Bun

Breakfast On A Bun costs $4.89 with 529 calories. It is fluffy scrambled eggs, your choice of sausage or bacon, and American cheese on the same toasted bun used across the burger line, served with mustard and diced onions unless you say otherwise.

It is the most ordered breakfast item Whataburger sells, and the reason is the bun. A soft toasted bun holds eggs better than a biscuit, so it travels to the car without falling apart. Breakfast runs from 11 pm to 11 am daily.

How to Make Breakfast On A Bun at Home?

The eggs are the difference here. Low heat, constant movement, and pull them a shade before they look done.

Tips

  • Low heat on the eggs. High heat makes them weep water into the bun.
  • Cheese goes directly on the hot eggs so it melts without a broiler.
  • Toast the bun in the meat fat, not dry butter, for the closest match.

Variations

  • Add a hash brown stick inside for texture.
  • Jalapenos for heat, which is a common Texas add.
  • Both bacon and sausage, which is essentially the Breakfast Burger build.

Serving Ideas

Pair with hash brown sticks at $1.99 and a hot coffee at $1.99.
