Juicy pork tenderloin coated in a tangy mustard glaze is a lean, high protein dinner that's elegant yet simple. Perfect for family dinners and clean eats meal plans alike.
Preheat oven to 425°F (218°C). Pat the pork tenderloin dry and season evenly with kosher salt and black pepper.
Heat olive oil in a large ovenproof skillet over medium-high heat. Sear the pork on all sides until golden brown, about 2-3 minutes per side.
In a small bowl, mix Dijon mustard, honey, apple cider vinegar, and garlic powder until smooth.
Brush the mustard glaze generously over the seared pork. Reserve a bit of glaze for basting midway through roasting.
Transfer skillet to the oven and roast for 15–20 minutes, or until the internal temperature reaches 145°F (63°C). Halfway through roasting, brush with the reserved glaze.
Remove pork from the oven and let it rest for 5–10 minutes before slicing to retain juiciness and avoid drying out.
