Recipe for Cooking Pork Fillet: Tender Medallions With Herb-Infused Crust

This recipe for cooking pork fillet delivers tender medallions with a golden herb crust every time. I developed this method after years of testing to ensure consistent results.

The key is searing the fillet quickly over high heat to lock in juices, then finishing in the oven. A simple herb rub creates that perfect crust without overpowering the pork's natural flavor.

You'll end up with juicy, tender pork that cuts like butter, with a fragrant herb crust that adds texture and depth. It's restaurant-quality without the complication.

Serve with roasted vegetables or mashed potatoes for a complete meal. David always requests seconds when I make this.

Ingredients for recipe for cooking pork fillet

Eleven ingredients deliver restaurant-quality tender pork with herb-infused crust every single time.

The pork tenderloin is non-negotiable here—look for uniform thickness (about 2-3 inches diameter) to ensure even cooking. Whole Foods and Costco carry excellent pre-trimmed options. Always check the color: it should be pinkish-red, never gray or brown. The herb combination of rosemary and thyme provides that classic French bistro flavor profile without overwhelming the pork's natural sweetness.

No fresh herbs? Dried at one-third the amount, but fresh is ideal for that vibrant crust. Substitute fresh sage for thyme if needed. The Dijon mustard can be swapped for whole grain in a pinch, though the texture will differ slightly. For the wine, any dry white works—Sauvignon Blanc or Pinot Grigio are safe bets. Skip the cooking wine; it's too salty.

Prep the herb mix up to 1 day ahead—store covered in the fridge. The cooked pork keeps 3-4 days refrigerated or freezes beautifully for 2 months. Always rest the meat 10 minutes before slicing to retain those precious juices.

Step-by-step instructions for cooking pork fillet

Master the technique for perfectly tender medallions with a flavorful herb crust every time.

In a small bowl, combine the 2 tbsp Dijon Mustard, 2 tbsp Fresh Rosemary, 2 tbsp Fresh Thyme, 4 cloves Garlic Cloves, 1 whole Shallot, 1.5 tsp Kosher Salt, and 1 tsp Black Pepper. Stir until the herbs and aromatics are evenly distributed throughout the mustard base.

Pat the 1.5 lb Pork Tenderloin completely dry with paper towels to ensure optimal searing. Trim any remaining silver skin, then coat the entire surface with the herb-mustard mixture. This creates a flavorful crust while tenderizing the meat. Let it marinate at room temperature for 15-20 minutes.

Heat 2 tbsp Olive Oil in a large oven-safe skillet over medium-high heat until it shimmers but doesn't smoke. Add the marinated pork tenderloin and sear for 3-4 minutes per side, turning only when it releases easily from the pan.

You're looking for a deep golden-brown crust on all sides. Use tongs to rotate the tenderloin, ensuring even contact with the pan. Add the remaining 1 tbsp Olive Oil as needed if the pan looks dry. The sear locks in juices while creating a flavorful fond for the sauce.

Transfer the skillet to a preheated 400°F oven and roast for 10-12 minutes or until the internal temperature reaches 140-145°F. The pork will continue cooking as it rests, reaching the safe 145°F temperature.

Remove from the oven and transfer the pork to a cutting board. Tent loosely with foil and let it rest for 10 minutes. This critical step allows the juices to redistribute throughout the meat, ensuring each slice remains moist and tender.

Place the skillet over medium heat and add the 1 whole Shallot (minced). Sauté for 1-2 minutes until softened. Deglaze the pan with 0.25 cup Dry White Wine, scraping up all browned bits with a wooden spoon.

Simmer until the wine reduces by half, then add 0.5 cup Chicken Stock. Continue simmering for 3-4 minutes until slightly thickened. Remove from heat, stir in the 2 tbsp Unsalted Butter until melted, then pour the sauce over sliced medallions. Serve immediately.

Dietary considerations for this dish

Gluten-Free Friendly

This pork fillet recipe is naturally gluten-free—no breadcrumbs or flour needed for that perfect crust. Just verify your Dijon mustard and chicken stock labels, as some brands add thickeners. I always grab Annie's or Maille mustard at Central Market. 💪

Low-Carb Option

At just 3g net carbs per serving without sides, this fits perfectly into keto and low-carb diets. The herb crust adds flavor without carbs. Skip the pan sauce if strictly counting, or thicken it with xanthan gum instead of butter.

Dairy-Free Adaptation

Simply replace the butter in the pan sauce with 2 tbsp olive oil or dairy-free butter. The sear and herb crust remain unchanged. Emma prefers this version—she’s my dairy-sensitive taste tester.

Paleo-Friendly

This recipe aligns with paleo guidelines as-is. All ingredients—pork, herbs, mustard, olive oil—are paleo-approved. Just ensure your wine and stock don’t contain additives. I’ve served this to paleo friends with rave reviews.

Allergen Note

The only potential allergens here are mustard and sulfites in wine. For mustard allergies, swap the Dijon for a mix of 1 tbsp apple cider vinegar and 1 tsp olive oil. Use beef stock instead of wine if needed.

Sodium Control

Cut the salt in half and use low-sodium chicken stock to reduce sodium by 40%. The herbs and mustard still pack plenty of flavor. David’s doctor recommended this tweak, and honestly, we can’t taste the difference.
