Chick-fil-A serves breakfast Monday through Saturday from 6:30 a.m. to 10:30 a.m., with breakfast service ending sharply at 10:30 a.m. The restaurant is closed on Sundays, so no breakfast is served that day. While most locations strictly adhere to this time frame, a few may offer a slight grace period if you arrive a couple of minutes after 10:30 a.m., but generally, breakfast is only available until 10:30 a.m. After breakfast hours end, Chick-fil-A switches to its lunch menu. The breakfast menu includes popular items like the Chicken Biscuit, Spicy Chicken Biscuit, Chick-n-Minis, Egg White Grill, Hash Brown Scramble Burrito, and more, but these breakfast items are not available all day.
