McDonald’s is kicking off its summer breakfast lineup with a spicy new limited-time release. Starting July 8, the fast food chain will offer Spicy McMuffin sandwiches at participating locations nationwide, each one topped with McDonald’s signature Spicy Pepper Sauce.

It’s the first time the sauce—previously featured on McDonald’s spicy chicken sandwiches—has made its way into the breakfast lineup. The new build sticks to the formula fans already know: an English muffin, melty cheese, Canadian bacon or sausage, and a freshly cracked egg now sourced from 100% cage-free eggs in the U.S., plus a smoky, pepper-forward sauce to add some kick. According to the McDonald’s Menu Spotter, the sandwich will be available in three builds: Spicy Egg McMuffin, Spicy Sausage McMuffin, and Spicy Sausage McMuffin with Egg.

The drop also comes as McDonald’s celebrates the 50th anniversary of the Egg McMuffin, which debuted nationally in 1975. Its origin dates back to 1971, when Santa Barbara franchisee Herb Peterson pitched the idea of a handheld Eggs Benedict to Ray Kroc.

In a statement released earlier this year as part of McDonald’s 50th anniversary campaign for the Egg McMuffin, David Peterson, the son of the sandwich’s creator, reflected on its legacy: “When I watched my father introduce this idea to Ray Kroc, we could not have anticipated it would become the foundation for the renowned McDonald’s breakfast menu…”

Joe Erlinger, McDonald’s USA president, echoed that sentiment in the same February announcement, noting: “Breakfast isn’t just a meal; it’s a cherished tradition and cornerstone of our brand…”

Spicy breakfast items aren’t new, but they remain a novelty on most drive-thru menus. As diners crave bolder morning flavors, heat has become a low-lift way for brands to rework familiar formats. While the Spicy McMuffin comes built with the sauce, some reports suggest customers might also be able to request it on other breakfast items, though McDonald’s hasn’t officially confirmed this.

The buzz picked up quickly on Instagram after snack account @snackolator posted about the launch. Fans shared their excitement in the comments. “This finna bang,” one wrote. “My stomach bubblin with excitement,” said another. Others swapped menu hacks — like using McDonald’s Mexican salsa packets to spice up a sausage McMuffin — or floated ideas for future upgrades, including a Spicy Chicken McGriddle or versions with pepper jack cheese.

Whether you’re a fan of the classic or just here for the kick, this one hits squarely in the zone of craveable, comfort-adjacent fast food. It’s not clear how long the Spicy McMuffin will stick around — but like most limited drops, it’s probably not forever.
