As part of the fast food chain’s 50th anniversary celebrations for the McMuffin, McDonald’s is releasing a series of new options to “spice up” its breakfast menu.

Starting July 8, McDonald’s is launching three spicy breakfast menu items: the Spicy McMuffin, Spicy Sausage McMuffin and Spicy Sausage McMuffin with Egg. The McMuffins will feature their traditional ingredients – cheese, egg, Canadian bacon or sausage, and a buttered English muffin, topped with Spicy Pepper Sauce, according to a news release.

McDonald’s launched the Egg McMuffin in 1975. The breakfast item was the brainchild of Herb Peterson, a McDonald’s franchisee in Santa Barbara, California. Herb, according to previous USA TODAY reporting, presented the sandwich as a to-go version of a diner classic: Eggs Benedict. Roy Kroc, the businessman who transformed McDonald’s into what it is today, loved the idea.

When will the Spicy McMuffin be available?

The Spicy McMuffin (and its subsidiaries) will be available for a limited time at participating locations starting on Tuesday, July 8.
