Why do my mozzarella sticks burst open when frying?
Usually one of four things: oil too hot, oil too cool (they sit longer and the cheese eventually finds a way out), thin spots in the breading, or not frozen long enough. Aim for 350°F and keep it there, use double breading, seal the ends when you press on crumbs, and freeze the breaded sticks for at least 1 hour.
Can I bake these instead of frying?
Yes. They will be a little less shatter-crispy, but still very good. Bake on a wire rack at 425°F for 10 to 12 minutes, flipping at the halfway mark. Freeze first so the cheese does not leak before the crust browns. For better browning, give the tops a light spritz of cooking spray or brush with a little oil.
Air fryer method?
Optional but helpful: preheat your air fryer for 2 to 3 minutes. Spray the breaded, frozen sticks with cooking spray. Air fry at 390°F for 6 to 8 minutes, turning once. Start checking around 6 minutes since models vary. Work in batches so air can circulate.
What kind of mozzarella works best?
Low-moisture, part-skim mozzarella string cheese is the most reliable. Fresh mozzarella has more water and tends to leak.
Do I really need panko?
No, but it helps. If you only have Italian breadcrumbs, use them. If you only have panko, add a little extra seasoning.
What oil should I use?
Use a neutral, high smoke point oil like canola, vegetable, peanut, or avocado oil. Avoid olive oil here, it is not the right vibe for deep frying.
