↓ Full nutritionPeople love it for the ultimate savory breakfast indulgence—the salty, umami-rich sausage and gooey cheese perfectly complement the buttery, slightly sweet croissant. It's a beloved, convenient staple that feels like a treat.
The high fat and refined carbohydrate content can lead to a blood-sugar spike and subsequent crash, making it a poor choice for sustained energy. To counteract this, pair it with a side of fiber-rich fruit or vegetables, and consider eating only half to manage portion size.
The 'Croissan'wich' is a trademarked portmanteau of 'croissant' and 'sandwich' created by Burger King in 1983.

How does the nutrition compare to a biscuit sandwich?
The croissant version is typically higher in fat and calories due to the butter-laminated dough, whereas a biscuit sandwich is higher in carbohydrates and often sodium.
Is the sausage pork or beef?
Burger King's standard sausage patty is primarily made from pork, seasoned with spices like sage and black pepper.
Can I make a healthier version at home?
Yes. Use a whole-grain croissant or English muffin, a lean turkey sausage patty, and add spinach or tomato to boost fiber and nutrient content.
