Frozen mozzarella sticks with Italian-seasoned breadcrumb coating, air-fried until golden and crispy with melted cheese centers. A classic appetizer or snack that delivers stretchy, gooey cheese contrasted with a crunchy exterior. Serve with marinara or ranch for dipping at parties, game day gatherings, or casual weeknight snacking.

Tips
Use a fork when dipping cheese in egg and flour to keep hands clean and prevent sticky fingers that make the next steps difficult.
Cook in small batches and remove immediately with tongs. The longer cheese sticks sit in the hot basket, the softer they become and the more likely cheese will leak.
If cheese begins oozing, line the basket bottom with aluminum foil sprayed generously with oil to catch leaks and maintain crispness.
Good to Know
Keep cooked cheese sticks in an airtight container in the refrigerator for up to 3 days. Reheat in air fryer at 350°F for 2-3 minutes to restore crispness. Frozen uncooked breaded sticks keep for up to 1 month.
Assemble and freeze breaded cheese sticks up to 1 month in advance. No need to thaw before air frying; add 1-2 minutes to cooking time if still frozen.
Serve immediately while still hot and crispy with marinara sauce and ranch dressing for dipping. Best enjoyed fresh from the air fryer.
Common Mistakes
Do not skip the initial 20-minute flash freeze; it prevents cheese from leaking during breading.
Do not skip the 45-minute final freeze; insufficiently frozen cheese will rupture and ooze during cooking.
Do not overcrowd the air fryer basket; cook in small batches so heat circulates evenly.
Do not leave cooked sticks in the basket; remove immediately with tongs to prevent softening from residual heat.

FAQ
Can I make these ahead and freeze them?
Yes, completely. After breading, freeze on the baking sheet for 45 minutes, then transfer to freezer bags for up to 1 month. Cook from frozen, adding 1-2 minutes to the cooking time.
What if the cheese starts leaking out during cooking?
Line the air fryer basket bottom with aluminum foil sprayed with olive oil for the next batch. This catches leaks and prevents cheese from contacting the heating element. Also ensure cheese is frozen solid before cooking.
How long can I keep cooked mozzarella sticks?
Refrigerate cooked sticks in an airtight container for up to 3 days. Reheat in the air fryer at 350°F for 2-3 minutes to restore crispness. Do not microwave as it makes them soggy.
