McDonald's said Tuesday that it is doubling down on breakfast by introducing bagel sandwiches nationwide to celebrate the Egg McMuffin's 50th anniversary. Why it matters: Breakfast is big business for fast-food chains and expanding menus can boost morning sales.

McDonald's has brought back its beloved breakfast bagel sandwiches nationwide, after limited releases in select U.S. markets.

First introduced in 1999, McDonald’s Bagel Sandwiches—then, an egg plus protein of choice—quickly gained fans for being a comprehensive breakfast on-the-go. According to New York Post, the global fast-food chain took standalone bagels off its breakfast menu in 2020.
