The “chicken wars” may be heating up again in the fast-food industry.

McDonald’s announced Tuesday that it will soon be introducing spicy chicken nuggets to its menu, an item popularized by competitor Wendy’s.

McDonald’s says it will start offering both Spicy Chicken McNuggets and Mighty Hot Sauce in the United States starting on September 16.

“Breaded with a sizzling tempura coating made of both cayenne and chili peppers, these craveable, dippable and downright-delicious Spicy Chicken McNuggets are joining our classic McNugget line up, and pack plenty of spice and flavor into each bite,” wrote McDonald’s in a press release.

The spicy nuggets and sauce will only be available for a limited time and at participating restaurants.

“This is the first time we’ve introduced a new flavor of our classic Chicken McNuggets in the U.S. since they came to menus in 1983,” said Vice President of Menu Innovation, Linda VanGosen.

The fast-food chain says the Mighty Hot Sauce is its first new sauce since 2017 and it will be the hottest one available at its restaurants.

“For those who care to dial up the heat, we’ve crafted our new Mighty Hot Sauce, boasting a powerful blend of crushed red peppers and spicy chilis,” said McDonald’s.

Additionally, McDonald’s says it will start selling a new McFlurry made with Chips Ahoy!

“This delicious treat features vanilla soft-serve, caramel topping and Chips Ahoy! cookie pieces blended throughout,” said McDonalds.

The Chips Ahoy! McFlurry will also be available for a limited time starting Sept. 16, in snack and regular sizes.

Chipotle is adding smoked brisket to its menus nationwide following a successful test conducted last year.

The chain said the limited-time offering, which is one of its most requested menu items, will go on sale Thursday. However, members of the chain's growing rewards program can get it two days early — beginning Tuesday — if they order through its website or on the app.

Chipotle described the brisket as "smoked to perfect tenderness" and seasoned with a blend of spices and a Mexican pepper sauce. It's also topped with a new sauce made with smoked chili peppers. The company said it took two years to develop a recipe that's "uniquely Chipotle."

Brisket was tested in November 2020 using the company's "stage-gate process" across more than 60 restaurants in Ohio and California. Chipotle adds new items to its menu at select restaurants and evaluates their performance before launching them nationwide. The most recent menu item it tested using this process was plant-based chorizo at locations in Denver and Indianapolis.

Other offerings that started in a few U.S. cities before expanding nationwide include riced cauliflower, carne asada and its popular quesadilla.

Chipotle has been performing well over the past few months, despite raising its menu prices by 3.5% to 4% to cover the costs of higher wages for employees and ingredients. In the second quarter, revenue grew 39% to $1.9 billion. Sales at restaurants open at least 13 months spiked 31%.

Shares of Chipotle are up 40% this year.
