Using a sharp serrated knife, carefully slice the keto-friendly bagel into very thin rounds, strips, or chip-sized pieces. Try to keep the slices as even as possible so they cook at the same rate and become evenly crispy in the air fryer. Thin slices work best because thicker pieces can stay chewy in the center instead of turning crunchy like chips. Don’t worry if some pieces look rustic or uneven — homemade bagel chips always look more natural and appetizing.

Place all the sliced bagel pieces into a medium mixing bowl and drizzle them lightly with avocado oil. Toss gently using your hands or a spoon until every piece has a light coating of oil. You only need a small amount because too much oil can make the chips greasy rather than crispy.

Sprinkle salt evenly over the bagel slices along with any additional seasonings you want to use. Garlic powder creates a savory snack flavor, everything bagel seasoning gives deli-style crunch, parmesan adds cheesy richness, and cinnamon with keto sweetener creates a sweet snack version. Feel free to customize the flavor depending on what you’re craving.

Toss the slices again thoroughly so the oil and seasonings coat every piece evenly. Make sure the seasoning reaches all sides of the bagel slices for the best flavor in every bite.

Preheat the air fryer to 350°F if your air fryer model recommends preheating. Starting with a hot air fryer helps the chips crisp faster and develop a better crunchy texture without drying out too much.

Arrange the seasoned bagel slices in a single layer inside the air fryer basket. Avoid heavily overlapping the pieces because crowded chips tend to steam instead of crisp properly. If necessary, cook them in batches for the best texture and even browning.

Air fry the bagel chips at 350°F for approximately 10 minutes, shaking the basket several times during cooking. Shaking helps prevent burning and allows all the chips to crisp evenly on multiple sides. The chips should gradually turn golden brown with darker toasted edges.

Once the chips are mostly crispy and deeply golden, lower the air fryer temperature to 200°F and continue cooking for another 2–3 minutes. This lower temperature stage helps dry out the centers slightly more and creates an extra crunchy texture without over-burning the outside edges.

Carefully remove the chips from the air fryer and spread them out slightly while they cool. The chips continue crisping as they rest, so don’t worry if they feel slightly soft immediately after cooking. After a few minutes, they become noticeably crunchier.

Serve the keto bagel chips with your favorite low-carb dip such as French onion dip, blended cottage cheese dip, guacamole, buffalo chicken dip, spinach dip, or creamy ranch dressing. They’re best enjoyed fresh while still crispy and warm for the ultimate high-protein keto snack experience.
