Pan-frying
The food touches a hot surface with a modest amount of oil. Choose it for thin pieces, eggs, fish, tofu, and anything where direct contact creates a useful crust.
Shallow-frying
Oil reaches partway up the food. It gives breaded cutlets and fritters more even color without filling a pot. Turn carefully with long tools, work in batches, and watch that the oil does not climb too high when food goes in.
Deep-frying
Food is submerged for fast, all-around cooking. It works especially well for loose batter, which can set in the oil rather than stick to a pan. Use a stable pot, ample headroom, dry food, a suitable oil thermometer, and a safe place to let oil cool.
Choose by the food
An egg or thin fish fillet needs contact with the pan, so start with pan-frying. A breaded cutlet browns more evenly when oil reaches partway up its side. A battered onion ring needs room to float, so deep-frying is the better fit. Change method only when it solves a texture problem.
Adjust batch size before the heat
Lay out the uncooked pieces near the stove and plan enough batches to leave space around each one. Adding too much food at once drops the oil temperature, slows browning and can leave the coating heavy. Keep a rack ready so finished pieces do not steam against a plate.
