Step 1

Preheat oven to 450 degrees. Pat pork tenderloin dry with paper towels then season all over with seasonings.

Step 2

Heat a thin layer of high heat cooking oil in a 11-12” cast iron skillet over medium-high heat. Sear pork tenderloin for 1-2 minutes on all four sides, or until golden brown on each side, then place the entire skillet into the oven and roast until the internal temperature reaches 140 degrees, 8-15 minutes. Transfer the pork tenderloin to a cutting board to rest while you make the pan sauce.

Step 3

Place skillet back over medium-high heat being VERY CAREFUL with the skillet handle as it will be extremely hot from the oven (I keep a hot pad on the handle so I don’t forget it's hot.) Add hard apple cider, maple syrup, and dijon mustard to the skillet then whisk to combine and simmer until sauce is slightly reduced, 5 minutes. Stir together water and cornstarch in a small bowl then pour into skillet and whisk to combine. Continue to simmer while occasionally whisking until sauce is thickened and glossy, 3-4 more minutes. Pour sauce through a fine mesh strainer or use a skimmer to remove any burnt herbs or bits if desired. Slice pork then serve with pan sauce.
