Ingredients
- 2 lbs pork tenderloin Two ~1 lb tenderloins, silver skin removed
- 1 tbsp olive oil For searing
Spice Rub
- 1 tsp brown sugar
- 1 tsp ground mustard
- 1 tsp garlic powder
- 1 tsp paprika Regular or smoked
- ½ tsp dried thyme
- ½ tsp dried oregano
- 1 tsp salt
- ½ tsp black pepper
Mustard Pan Sauce
- 2 tbsp unsalted butter
- 3 cloves garlic
- ½ cup dry white wine Or substitute chicken broth
- ¾ cup heavy whipping cream Do not substitute half-and-half
- 2 tbsp Dijon mustard
- ¼ tsp dried thyme
- Fresh parsley Fresh parsley
Instructions
- Step 1 — Make the spice rub & prep the porkIn a small bowl, combine brown sugar, ground mustard, garlic powder, paprika, thyme, oregano, salt, and pepper. Whisk together until well mixed. Trim the silver skin from both tenderloins, then let the meat rest at room temperature for 30 minutes before cooking.Step 2 — Preheat & seasonPreheat your oven to 400°F. Pat the pork completely dry with paper towels. Press the spice rub firmly over all sides of each tenderloin, coating evenly.Step 3 — Sear the porkHeat a large oven-safe skillet over medium-high heat until very hot. Add the olive oil and let it shimmer. Place the tenderloins in the pan and sear undisturbed for 3–5 minutes per side, until each side is deep golden and releases easily from the pan.Step 4 — Roast in the ovenTransfer the skillet directly into the preheated oven. Roast for 10–15 minutes, or until an instant-read thermometer inserted at the thickest part reads 145°F. Remove just before reaching 145°F as the meat will continue cooking while it rests.Step 5 — Rest the meatTransfer the pork to a cutting board and tent loosely with foil. Rest for 5 minutes while you build the sauce.Step 6 — Build the mustard pan sauceReturn the skillet to the stove over medium heat. Add the butter and let it melt, scraping up all the caramelized bits from the bottom of the pan. Add the minced garlic and cook for 1 minute, stirring constantly.Step 7 — Finish the sauce & servePour in the white wine (or broth) and stir to combine. Add the heavy cream, Dijon mustard, and thyme. Let the sauce simmer for 2–3 minutes, stirring occasionally, until slightly thickened and glossy. If too thick, add a splash more wine or broth. Slice the pork, spoon the sauce generously over the top, garnish with fresh parsley, and serve immediately.
Notes
- Silver skin must go. That thin, pearlescent membrane along the side of the tenderloin doesn't break down during cooking and will cause the meat to curl and toughen. Slide a sharp knife under it and pull it away before seasoning.
- Room temperature matters. Pulling the pork out 30 minutes before cooking helps it sear and roast more evenly. Cold meat in a hot pan leads to an overcooked exterior and undercooked center.
- Don't rush the sear. A hot, dry pan is what creates that golden crust. If the meat is sticking, it's not ready to flip — give it another minute.
- Pink is fine. Pork at 145°F is fully safe to eat, even if a pale pink blush remains in the center. That's actually the perfect doneness for tenderloin.
- Store leftovers with sauce. Keep leftover pork and sauce together in an airtight container in the fridge for up to 4 days. The sauce helps the meat stay moist. Freeze cooked pork for up to 3 months; thaw overnight in the fridge before reheating.
