Pressure Cook Pork Tenderloin:
Set aside the pork. Add 1 cup (250ml) unsalted chicken stock, then deglaze the bottom of the pot. Turn off the heat briefly. In a small bowl, mix 1 tsp (0.5g) dried oregano, 1 tsp (2g) dried sage, 1 tsp (1g) dried rosemary, and 3 (14.6g) finely minced garlic cloves together. Apply Dry Rub to all sides of the browned pork tenderloin, then place pork in Instant Pot. Pressure Cook at High Pressure for 0 minute, then 15 minutes Natural Release.
*Note: 0 minute (zero minute) is not a typo! We're using the heat from "Pressurize" Stage & "Depressurize" Stage to cook the pork tenderloin. We tested various pork tenderloin in Instant Pot to find this best cooking time & method. Read the details here
*Pro Tip: If your pork tenderloin is thicker than 1.5", increase the natural release time (~5 - 6 minutes per 0.5" of thickness).
