Overview
Tonkatsu is one of Japan's most beloved comfort foods - a tender pork cutlet coated in crispy panko breadcrumbs and served with tangy-sweet tonkatsu sauce, shredded cabbage, and rice. Sous vide ensures the pork stays perfectly juicy inside while the panko coating creates an ultra-crispy exterior.
Core Time & Temperature
| Doneness | Temperature | Time | Max Time |
|---|---|---|---|
| Tender | 140°–145°F | 1 h 30 min–2 h | 4 h |
Cooking time depends on thickness. Tonkatsu cutlets are typically 3/4 to 1 inch thick.
Food Safety Notes
Pork should reach at least 145°F / 63°C per USDA guidelines. Cooking at 140°–145°F for 1 h 30 min–2 h ensures pasteurization. The deep frying adds additional heat. Modern USDA guidance allows pork at 145°F with a three-minute rest. Hold the bath long enough to pasteurize and finish with a hard sear to kill surface bacteria.
