How many calories is a lobster roll with butter?

A lobster roll is a popular New England sandwich made with lobster meat served on a grilled hot dog bun or similar roll. The classic preparation involves lightly dressing the lobster with mayonnaise or butter. Adding butter contributes additional calories to this seafood sandwich.

Quick Answer

A typical lobster roll with butter contains approximately 500-700 calories, depending on the exact size and ingredients. A standard lobster roll made with a 3-4 ounce lobster meat serving and 1-2 tablespoons of butter easily provides 500-600 calories. Larger sandwich sizes with extra butter can reach 700+ calories.

Detailed Calorie Breakdown

There are several factors that determine the calorie content of a lobster roll:

  • Lobster meat amount – More ounces of lobster means more protein and calories.
  • Bun size and type – Larger, enriched buns add more carbs and calories.
  • Butter or mayonnaise – Butter contains about 100 calories per tablespoon.
  • Additional ingredients – Onions, celery, herbs, lemon juice, salt, etc.

Here is a detailed calorie breakdown for a typical lobster roll with butter:

Lobster Meat

A standard lobster roll contains between 3-5 ounces of lobster meat. Lobster provides about 30 calories per ounce. So 3-5 ounces of lobster contributes 90-150 calories to the sandwich.

Hot Dog Bun

A basic hot dog bun provides about 120-150 calories. A New England-style split-top bun likely adds closer to 150 calories.


Most lobster rolls are dressed with 1-2 tablespoons of melted butter. Each tablespoon of butter contains about 100 calories.


If mayonnaise is used instead of butter, each tablespoon contains about 90-100 calories.

Onions, Celery, Herbs

Small amounts of onions, celery, chives, parsley, tarragon, and other herbs add minimal extra calories.


Adding up these typical amounts:

  • 4 ounces lobster: 120 calories
  • 1 hot dog bun: 150 calories
  • 2 tbsp butter: 200 calories

This leads to a total of about 470 calories in a classic lobster roll with butter.

Size Variations

The size of the lobster roll can alter the calorie content:

  • 3 ounce smaller lobster roll with 1 tbsp butter – about 400 calories
  • 5 ounce larger lobster roll with 2 tbsp butter – around 600 calories
  • Jumbo 8 ounce lobster roll with extra butter – up to 800+ calories

Factors That Increase Calories

Certain additions can significantly increase the calories in a lobster roll:

  • Larger, enriched buns – up to 200-300 calories
  • Extra butter – each tbsp is ~100 calories
  • More mayonnaise – ~90-100 calories per tbsp
  • Fried lobster meat
  • Bacon – 50+ calories per slice
  • Avocado – about 50 calories per ounce
  • Fried onions – 20-30 calories per tbsp

With enough large additions, some indulgent lobster rolls can reach 1000+ calories.

Low Calorie Lobster Roll Options

You can reduce the calories in a lobster roll by:

  • Cutting back on butter/mayo
  • Using a lighter bun
  • Increasing celery, onions, and herbs
  • Seasoning with lemon juice instead of butter
