How many calories does a breakfast on a Bun from Whataburger have?

Whataburger’s Breakfast on a Bun is a popular breakfast sandwich option for those looking for a convenient and tasty morning meal. However, with society’s increasing focus on healthy eating and calorie counts, many Whataburger fans wonder just how many calories are in this sandwich. This article will provide a detailed breakdown of the Breakfast on a Bun’s nutritional information to help readers understand its caloric content.

What is the Breakfast on a Bun?

The Breakfast on a Bun is one of Whataburger’s signature breakfast sandwiches. It features a freshly cracked egg, slice of melted American cheese, and slice of ham served on a toasted bun. The classic version comes with just egg, cheese, and ham, but customers can customize it by adding bacon, sausage, or an extra meat. The sandwich provides a satisfying mix of protein, carbs, and fat to start the day off right. Its portability makes it a convenient choice for eating on the go or even in the car on the morning commute. For many Whataburger fans, the Breakfast on a Bun is a go-to order for a reliable and tasty quick breakfast.

Nutritional Content

When examining the nutritional breakdown of the Breakfast on a Bun, there are a few key factors to consider:


The classic Breakfast on a Bun with egg, cheese, and ham contains 360 calories. Here is how those calories break down:

  • Bun: 210 calories
  • Egg: 80 calories
  • Cheese: 50 calories
  • Ham: 20 calories

The bun accounts for the majority of the calories at 210. An average hamburger bun contains 200-300 calories, so Whataburger’s bun falls right in that range. The egg and cheese provide protein and fat for satiety, while the deli ham adds a lean protein.

If you customize by adding bacon or sausage, the calorie count will increase:

  • Add bacon: +60 calories
  • Add sausage: +140 calories

So a Breakfast on a Bun customized with bacon would contain 420 calories total. With sausage, it would be 500 calories. Sticking to the classic ham version keeps the calorie count lowest.


In addition to calories, let’s look at the macronutrient breakdown:

Macronutrient Amount
Protein 19g
Carbohydrates 29g
Fat 18g

The sandwich provides a balanced nutritional profile. The protein comes mainly from the egg and deli ham. The carbs are found in the bun, while the fat content comes mostly from the cheese and egg yolk. This combo of protein, carbs, and fat helps you feel satisfied and energized to start the day.


While the Breakfast on a Bun is not a significant source of vitamins and minerals, here are some of the micronutrients it contains:

  • Calcium: 15% Daily Value
  • Vitamin A: 10% DV
  • Vitamin D: 15% DV
  • Vitamin B12: 15% DV
  • Selenium: 13% DV

The cheese provides calcium and vitamin D, while the egg yolks contain vitamin A, vitamin D, vitamin B12, and selenium. The bun also has a small amount of B vitamins like thiamin and folic acid. So while the Breakfast on a Bun won’t meet all your vitamin and mineral needs for the day, it does contribute some.

How Does It Fit into Your Daily Calorie Needs?

To determine if the Breakfast on a Bun fits into your daily caloric needs, you’ll need to consider your individual situation:

  • Recommended daily calorie intake: The average sedentary adult requires about 2000 calories per day. More active individuals need more calories.
  • Meal timing: The Breakfast on a Bun makes a more balanced option if it’s replacing a lighter breakfast, rather than a high calorie meal later in the day.
  • Rest of diet: If the rest of your meals are low or moderate in calories, the Breakfast on a Bun can likely fit into your day. But if you consume a lot of calorie dense foods otherwise, it may be too much.
  • Nutrition goals: Those wanting to lose weight will need to account for the Breakfast on a Bun’s 360 calories. People with other goals like muscle gain may appreciate the extra calories.

Overall, the Breakfast on a Bun can fit into most calorie budgets in moderation. Having it occasionally or customizing it to be lower calorie (like skipping the cheese) can help keep it in balance. It provides a nutrient dense start to the day for many Whataburger customers.

How Does It Compare to Other Fast Food Breakfast Sandwiches?
