When placing a drive-thru order for an egg sandwich, one might expect there to be an actual egg inside. However, a review of the ingredients found in popular breakfast products sold in stores fast food chains shows that some restaurants are selling items that might not contain what customers consider “100% real eggs.”
The United States Department of Agriculture Food Safety and Inspection Service (FSIS) notes that food manufacturers often use pasteurized egg products because of their convenience and ease of handling and storage.
Egg products must also be edible without additional preparation to ensure food safety, according to FSIS. This makes egg products processed in Department of Agriculture-inspected sanitation facilities more attractive to fast-food chains, restaurants and healthcare facilities like hospitals and nursing homes.

The chain’s signature round egg, found on an Egg McMuffin, is made with a USDA Grade A egg broken into an “egg ring.”
However, according to McDonald’s, scrambled and folded eggs – like those on a bacon, egg and cheese biscuit – are made with liquid eggs that are pre-cooked and folded before being frozen by its suppliers. Once they arrive at a local kitchen, they are prepared on a grill with real butter.
McDonald’s Sausage Burrito Eggs are pre-cooked liquid eggs containing ingredients such as: sausage, tomatoes, green chilies, onions and seasonings, before flash freezing to help lock in their taste, according to the company.

Starbucks says its breakfast sandwich contains “whole eggs,” but the lengthy list of additives that follows sets the item apart from something you might find in a grocery store or home refrigerator.
Some of the additives listed include: water, soybean oilmodified food starch, whey solids and citric acid, depending on nutritional value.
Other breakfast menu items, such as egg bites, list egg whites along with other additives.

Panera offers an egg sandwich made with a freshly cracked egg, which launched at the same time the company asked the FDA to clearly define what an “egg” actually is.
The company claimed in 2018 that FDA regulations did not establish a definition or standard for eggs and that many chains offered egg products containing more than a dozen additives.
However, it appears that not all of Panera’s breakfast items are made with freshly cracked eggs, as some still contain pasteurized eggs or liquid whole eggs.
