Introduction – Overview of hamburger buns and calories

The hamburger bun has been an integral part of the classic American hamburger since the early 1900s. Not only does it add taste and texture, but it also makes the juicy burger easier to handle and eat.

But with rising rates of obesity and diabetes, more consumers are paying attention to calories and nutritional content – and that includes hamburger buns. So how many calories are actually in a hamburger bun?

The average plain hamburger bun contains around 120 calories. However, calories can range from 80 in a slider bun up to 200 in a large bakery-style bun depending on size, ingredients, and type of bun. Whole wheat buns tend to be slightly higher in calories than white hamburger buns.

Below we’ll explore all the factors that affect hamburger bun calories and provide detailed estimates for different bun varieties. We’ll also offer tips for estimating and reducing calorie intake from your burger bun.

Factors Affecting Hamburger Bun Calories

Several key factors determine the calorie content of a hamburger bun, including:

Bun Size

  • Standard buns – These average 4-4.5 inches wide and contain around 120 calories. They are the typical size used for burgers at home or restaurant chains.
  • Slider or mini buns – Smaller buns for sliders are only about 3 inches wide and contain 60-100 calories. Their compact size means fewer calories per bun.
  • Large or bakery-style buns – Jumbo buns can be up to 5-6 inches wide and contain 150-200 calories. The larger size causes the big jump in calories.

Bun Type

  • White enriched buns – The classic white burger bun made with refined flour is typically lowest in calories at around 120 per bun. White flour is more processed but also lower in calories than whole wheat.
  • Whole wheat buns – Wheat buns contain more fiber and nutrients, bumping calories up to 130 per bun. Whole grains are higher in protein and fiber.
  • Brioche – Buttery, eggy brioche buns average 170 calories. The higher fat content increases calories.
  • Pretzel buns – These dense, chewy buns can have 160-200 calories. Pretzel dough is richer than standard bread dough.

Added Ingredients

  • Butter or oil – Brioche, challah, and other enriched buns made with added butter or oils are higher in fat and calories. One tbsp of butter is 100 calories.
  • Cheese – Cheeseburger buns or those topped with cheese contain extra calories from the cheese. Just one ounce of cheddar cheese is 110 calories.

Calorie Ranges for Different Bun Sizes and Types

Use this handy chart to estimate calories for different types and sizes of hamburger buns:

Bun TypeServing SizeAverage Calories
White hamburger bun1 medium (4″ bun)120 calories
Whole wheat hamburger bun1 medium (4″ bun)130 calories
Brioche bun1 medium (4″ bun)150-180 calories
Pretzel bun1 medium (4″ bun)160-200 calories
Slider or mini bun1 small (3″ bun)80-100 calories
Jumbo bakery-style bun1 extra large (5-6“ bun)180-200 calories

As you can see, the typical medium white hamburger bun containing 120 calories is a good baseline. Whole wheat, fancy buns, and oversized buns skew higher in calories, while slider buns are lower.

Store-Bought vs. Homemade Buns

What about the difference between store-bought and homemade buns?

Store-bought enriched white buns from major brands average 120 calories. They offer convenience but also tend to contain preservatives and additives.

Homemade buns using basic ingredients like flour, yeast, salt, and water are also around 120 calories for a standard 4-inch bun. However, homemade buns lack preservatives so won't keep as long.

The calories are very similar between basic homemade and store-bought buns. Where you see a difference is in specialty homemade buns made with added butter or eggs, which increases the calorie count, or homemade whole wheat buns which are slightly higher in calories than white.

Ingredients Comparison – White vs. Wheat, Fats, and More

Why do some buns have more calories than others? It comes down to the ingredients.

  • White vs. wheat flour – Whole wheat flour contains more protein, fiber, and overall nutrition than white flour. This increases the calories by about 10 per bun.
  • Added fats – Butter, oil, eggs, and cheese all contain fat and calories. Just 1 tbsp of butter adds 100 calories!
  • Sugars – Some sweet buns like Hawaiian rolls contain added sugars that can increase calorie count.
  • Salt – Salt has no calories but can increase perceived flavor and lead people to eat more buns.
  • Mix-ins – Nuts, seeds, dried fruit, and other mix-in ingredients contribute extra calories.

To minimize calories, choose plain buns made with simple ingredients like white or wheat flour, yeast, and water. Avoid added fats, sugars, and cheese.

Cooking Methods for Buns – Boiled vs. Baked

Does the cooking method impact the calories in a hamburger bun?

Baked buns and boiled buns have very minimal differences in calorie density since the main ingredients are the same. However, boiling uses water so there is opportunity for some vitamins and minerals to leach out.

Baked buns will retain more nutrients overall and have a preferable texture for burgers. Baked buns at 350°F for 15-20 minutes provide the classic burger bun taste and texture with no difference in calories compared to boiled.

Pairing Hamburger Buns with Foods

Hamburger buns aren't just for burgers! Consider these other delicious ways to enjoy your buns:

Best Burger Toppings

Lettuce, tomato, onion – classic fresh veggies
Avocado – healthy fat and creaminess
Sautéed mushrooms – rich umami flavor
Fried egg – protein and richness
Crispy bacon – salty crunch and smokiness


Turkey, ham, or tuna salad sandwiches
BLT with crunchy bacon
Grilled cheese for comfort food
Chicken, beef, or pork cutlet sandwiches

Hot Dogs

Buns are made for hot dogs too! Opt for slider buns to reduce calories.

Breakfast Sandwiches

Sausage, egg, and cheese breakfast sandwiches
Bacon, egg, and cheese for extra protein
Breakfast burrito wrapped in a tortilla instead of bun

Get creative with burger buns as the bread for any sandwich or wrap. Splitting with a friend helps control portions and calories too.

Bun Alternatives for Different Diets

People following specialized diets can also enjoy burgers and sandwiches with these bun alternatives:


Lettuce leaf wraps
Portobello mushroom caps
Cheese “buns” made from sliced cheese


Gluten-free bread or buns
Lettuce wraps
Sweet potato “buns”


Lettuce leaves
Portobello caps
Grain-free cassava or coconut flour buns


Lettuce wraps
Cheese buns
Small slider buns

With a little creativity, you can find an alternative lower-calorie, diet-approved option to substitute for traditional buns. Consider ingredients you already enjoy on burgers and use those as wraps or veggie swap-ins.

Buns Around the World

While the classic round hamburger bun is distinctively American, other cuisines use their own unique breads and rolls:

  • India – Try a chicken tikka sandwich served on flatbreads like naan or roti.
  • Mexico – Fold burrito fillings into a soft flour tortilla in place of a bun.
  • Vietnam – Fill a baguette with grilled meat and pickled veggies for a Banh Mi sandwich.
  • Middle East – Stuff pita bread with shawarma spiced meat and hummus.
  • Italy – Go for a panini press grilled sandwich on focaccia or ciabatta bread.

Venturing outside the standard burger bun provides exposure to new flavors and textures. Experiment with ethnic breads and flatbreads to addinterest and save calories.

History and Origin of the Hamburger Bun

While the hamburger patty dates back to medieval times, putting it on a bun is believed to have originated in the early 1900s in America.

  • 1921 – A bun recipe is included in Julia Davis Chandler’s ‘Liberty Cook Book’ designed for WWI soldiers.
  • 1921 – The first hamburger bun patent was issued to John F. Saxe.
  • Mid-1920s – White Castle starts serving burgers on buns rather than just between bread slices.
  • 1940s – McDonald’s pioneers fast food burgers served on sesame seed buns.

The burger bun took the sandwich concept and applied it to the convenient finger food of hamburgers. Its adoption paralleled the rise of fast food and American on-the-go culture.

Storage, Shelf Life, Freezing Buns

Proper storage preserves freshness and reduces waste of hamburger buns:

  • Store in original packaging at room temp up to 3 days.
  • For longer shelf life, refrigerate up to 7 days.
  • Freeze for up to 3 months; thaw at room temp or toast from frozen.
  • Moldy or dried out buns should be discarded.
  • Slice frozen buns and reheat or toast before using.

Storing buns in the fridge or freezer keeps them fresh and extends their shelf life. This helps reduce trips to the bakery or having to throw away stale buns.

Nutritional Benefits of Hamburger Buns

Despite their calorie and carbohydrate content, hamburger buns can also provide some key nutrients:

  • Fiber – A whole wheat bun provides about 2-3 grams of dietary fiber, while white buns have 1-2 grams. Fiber aids digestion.
  • B Vitamins – Enriched bread products like buns are fortified with B vitamins including thiamin, riboflavin, niacin, and folic acid. These support metabolism and cell function.
  • Iron – The enrichment process also adds iron to bread. Just one bun contains 5-10% of the recommended daily intake for iron, which prevents anemia.
  • Carbohydrates – The carb content of buns can help boost energy levels. The combo of protein and carbs makes it a balanced meal.

Choosing whole grain buns maximizes nutrition. But even white enriched buns play a role in a healthy diet in moderation.

The Bottom Line – Typical Calories and Recommendations

In summary, a plain medium white hamburger bun contains around 120 calories, while whole wheat buns average 130 calories. Small slider buns may have only 80-100 calories, while large bakery-style buns can go up to 200 calories.

Specialty brioche, pretzel, and cheeseburger buns also tend to be higher in fat and calories. Check labels for nutrition facts. When dining out, inquire about getting a smaller bun size.

Splitting a burger with a friend, skipping the bun, or substituting a lettuce wrap are other ways to cut calories and carbs while still enjoying a tasty burger. Moderation and thoughtful choices are key to fitting hamburger buns into a balanced diet.

With the right techniques for storage, freezing, and reheating, you can always have fresh hamburger buns ready for your next cookout or sandwich creation. Your favorite burger or sandwich would not be complete without the standard American hamburger bun!
