Ingredients
Scale
- 1 pork tenderloin (about 1 to 1.25 lbs), trimmed
- 2 cups apple cider (not apple juice)
- 2 tbsp apple cider vinegar, divided
- 1 tbsp dijon mustard
- 2 tbsp neutral oil
- 3 tbsp unsalted butter, cold and cubed
- 3 cloves garlic, smashed
- 4 sprigs fresh thyme or sage
- Salt and black pepper
- Flaky salt, for serving
Instructions
- In a small saucepan, simmer the apple cider over medium heat until reduced to about 1/3 cup and syrupy, 15-20 minutes. Watch closely in the last few minutes; pull it the moment it coats a spoon. Off heat, whisk in 1 tbsp of the cider vinegar. Set aside.
- Pat the pork tenderloin dry, season generously with salt and pepper, and rub all over with dijon mustard.
- Heat oil in a heavy skillet over medium-high heat. Sear the pork on all sides until deeply browned, about 8-10 minutes total. Add garlic and thyme to the pan in the last 2 minutes.
- Reduce heat to medium. Brush the pork all over with the cider syrup and continue cooking, turning and basting, until a thermometer inserted in the thickest part reads 137-140°F, about 5-8 more minutes.
- Transfer pork to a cutting board, tent loosely with foil, and rest 10 minutes; it will climb to about 145°F.
- While it rests, return the skillet to medium heat. Add remaining 1 tbsp cider vinegar and any remaining syrup, scraping up the browned bits. Remove from heat and whisk in cold butter a piece at a time until glossy.
- Slice the pork, spoon the pan sauce over the top, and finish with flaky salt.
Notes
Use fresh-pressed or unfiltered apple cider, not apple juice—juice lacks the tannin and acidity to reduce into a proper glaze. A digital instant-read thermometer is essential here; pull the pork earlier than instinct tells you. For a deeper glaze, substitute half the cider with a dry hard cider. Leftovers reheat gently in a low oven with a splash of stock to loosen the sauce.
