How many calories in a breakfast croissant sandwich?

A breakfast croissant sandwich can be a convenient and delicious start to the day, but it’s important to pay attention to the calorie count. The number of calories in a croissant sandwich can vary widely depending on the specific ingredients and portion sizes. In this article, we’ll break down the typical calorie counts for different components of a breakfast croissant sandwich to help you make informed choices.

Calories in a plain croissant

The foundation of a croissant sandwich begins with the croissant itself. Plain croissants can range from about 150 to over 300 calories each depending on the size. A small 2 ounce croissant may have around 150 calories. A medium 3 ounce croissant may have around 200 calories. Large jumbo croissants may have 300 calories or more.

For example, here are the calories for some common plain croissant sizes from various restaurants and bakeries:

Plain Croissant Calories
Small (2 oz) 150
Medium (3 oz) 200
Large (4 oz) 260
Jumbo (5 oz) 325

As you can see, the calories add up quickly as the size increases. When building your own sandwich, opting for a smaller croissant is an easy way to trim calories.

Calories in meat, egg, and cheese

In addition to the croissant itself, some of the most common breakfast sandwich fillings are meat, egg, and cheese. These all contribute additional calories to the sandwich.

For meat, three common options are ham, bacon, and sausage. Two slices of lean ham may have around 50 calories. Two slices of bacon can have 100 calories or more depending on the type. And a sausage patty may have 200 calories or more.

For egg, a large fried egg may have around 90 calories, while an omelet style egg may have 50 calories or less.

Cheese choices like cheddar, Swiss, and American add 50 to 80 calories per slice. Reduced fat cheese slices may have around 45 calories.

Here’s a table summarizing the approximate calories for common breakfast sandwich meats, eggs, and cheese:

Ingredient Calories
2 slices lean ham 50
2 slices bacon 100
Sausage patty 200
Fried egg 90
Omelet style egg 50
Cheese slice 50-80

Calories in spreads and sauces

Don’t forget to account for any additional spreads and sauces added to the sandwich. These can quickly drive up the calorie count.

For example, a tablespoon of regular mayonnaise or butter adds about 100 calories. Reduced fat mayo has around 35 calories per tablespoon. Mustard has about 5 calories per teaspoon.

If the croissant is spread with butter before toasting, that’s an additional 100 calories or more.

Here are the approximate calories for common breakfast sandwich spreads:

Spread/Sauce Calories
1 Tbsp mayo 100
1 Tbsp reduced-fat mayo 35
1 tsp mustard 5
1 Tbsp butter 100

Putting it all together

When you add up a croissant, meat, egg, cheese, and sauces, the calorie count quickly climbs. A small croissant sandwich with lean ham, cheese, and mustard can come in around 300-400 calories. A larger sandwich with bacon, egg, cheese, and mayo can easily be 600-800 calories or more.

To get a better idea, here are the approximate calories for some common breakfast croissant sandwiches from various restaurants:

Breakfast Croissant Sandwich Calories
Egg, Cheese, Ham on Small Croissant 300-400
Egg, Bacon, Cheese on Medium Croissant 500-600
Sausage, Egg, Cheese on Large Croissant 600-700
Bacon, Egg, Cheese, Mayo on Jumbo Croissant 700-800

Tips for reducing calories

If you want to lighten up your breakfast sandwich, here are some tips to reduce the calorie count:

  • Choose a smaller croissant size
  • Pick lean ham or Canadian bacon over sausage or bacon
  • Use just egg whites rather than whole eggs
  • Opt for reduced-fat cheese
  • Limit high-calorie sauces and spreads
  • Load up on veggies like tomato, spinach, and avocado

With some simple substitutions and smart choices, you can enjoy a tasty breakfast croissant sandwich for around 400 calories or less.

Nutritional benefits of breakfast sandwiches

While calories are important to consider, breakfast sandwiches also provide important nutrients to fuel your day. Some of the nutritional benefits include:

  • Protein – The eggs, meat and cheese provide filling protein to help you feel satisfied.
  • Calcium – The cheese contains bone-strengthening calcium.
  • Iron – Meat supplies iron to support healthy blood and energy levels.
  • B vitamins – Eggs provide riboflavin, niacin, pantothenic acid and other B vitamins.
  • Fiber – The croissant offers a small source of fiber for digestion.


Breakfast croissant sandwiches can make a tasty and convenient meal. But the calorie count can vary widely. A small croissant with lean fillings may have around 300-400 calories. Large sandwiches with fatty ingredients like bacon and cheese can exceed 700-800 calories. To lighten up your sandwich, opt for a smaller croissant, egg whites instead of whole eggs, reduced-fat cheese, and easy on the sauces. With smart choices, you can enjoy a satisfying breakfast sandwich within a reasonable calorie budget.
