Jamie Oliver’s Pork Fillet Medallions Recipe: Pan-Seared with Herb Butter Glaze

Pan-seared pork fillet medallions with herb butter glaze bring restaurant-quality results to your home kitchen. This method delivers tender meat with a golden crust every time.

I developed this approach after years of trial and error, learning that high heat and proper timing are everything. The herb butter adds layers of flavor without overwhelming the natural pork taste.

You’ll achieve juicy medallions with a caramelized exterior and a velvety herb sauce that pools beautifully on the plate. Each bite combines perfectly cooked pork with aromatic herbs.

Serve these medallions with roasted vegetables or mashed potatoes for a complete meal. The technique is simple but delivers impressive results.

Ingredients for Pork Fillet Medallions Recipe Jamie Oliver

Pantry staples meet a few fresh herbs for these juicy medallions with golden crust.

The pork is the star here. Pork fillet (also called tenderloin) stays tender—avoid center-cut chops, which can dry out. Whole Foods or Costco have great options, but most supermarkets carry it pre-trimmed. Look for even thickness so medallions cook uniformly. The herbs? Fresh rosemary and thyme add that aromatic punch (dried just won’t cut it).

No white wine? Chicken stock with a splash of lemon juice works in a pinch. Fresh thyme can be swapped for tarragon if you’ve got it. The Dijon mustard adds depth, but whole-grain mustard gives a nice texture. For a richer glaze, brown the shallots a bit longer. If the medallions brown too fast, lower the heat—patience pays off here.

Leftovers keep 3-4 days in the fridge, but the herb butter is best fresh. Freeze cooked medallions for up to 3 months (reheat gently in a pan). The glaze can be made ahead—just warm it slowly before serving.

Step-by-Step Instructions for Pork Fillet Medallions with Herb Butter Glaze

This method delivers tender pork with a glossy glaze and restaurant-worthy presentation.

Step 1: Prep and Season the Pork Medallions

Trim the 1.5 lb pork fillet of any excess fat and silver skin, then slice into 1-inch thick medallions. Pat each piece completely dry with paper towels—this ensures a proper sear instead of steaming.

Season both sides generously with 1 tsp kosher salt and ½ tsp black pepper. I always use freshly ground pepper for better flavor. Let the seasoned medallions sit at room temperature for 10 minutes while you prep the herb butter.

Step 2: Create the Aromatic Herb Butter

In a small bowl, combine 4 tbsp unsalted butter (softened), 2 tbsp fresh rosemary, 2 tbsp fresh thyme, and 3 cloves minced garlic cloves. Mash everything together with a fork until the herbs are evenly distributed throughout the butter.

This compound butter will melt over the pork as it cooks, infusing every bite with fragrant herb and garlic flavor. Set it aside while you sear the meat—don’t let it sit too long or the herbs will start to oxidize and lose their vibrant color.

Step 3: Sear the Medallions to Golden Perfection

Heat 2 tbsp olive oil in a large skillet over medium-high heat until it shimmers. Add the pork medallions in a single layer, being careful not to overcrowd the pan. Sear undisturbed for 3-4 minutes per side until deep golden brown and the internal temperature reaches 145°F.

During the last minute of cooking, top each medallion with a dollop of the herb butter. Baste the pork with the melting butter by tilting the pan and spooning the foamy mixture over the top. This creates a beautiful lacquered finish.

Step 4: Build the Pan Sauce

Transfer the pork to a warm plate and tent with foil. Reduce heat to medium and add the 1 whole finely minced shallot to the pan. Cook for 1 minute until softened, stirring to pick up any browned bits.

Deglaze with ½ cup white wine, scraping the fond from the bottom. Simmer for 2 minutes until reduced by half, then add ½ cup chicken stock, 1 tsp Dijon mustard, and 1 tsp honey. Whisk in the remaining 2 tbsp unsalted butter until the sauce is glossy.

Step 5: Plate and Serve

Spoon the warm sauce over the pork medallions. I like to garnish with any remaining fresh herbs from the stems. The sauce should be rich but balanced, with the acidity from the wine cutting through the butter.

Serve immediately while the pork is still warm. The medallions should be juicy with a slight blush in the center, and the herb butter will have created a fragrant crust on top. Pair with mashed potatoes or roasted vegetables to soak up that incredible sauce.

Common Mistakes When Making This Recipe

Overcrowding the Pan

Never cook all 1.5 lb pork fillet medallions at once—this drops pan temperature, causing steaming instead of searing. I learned this the hard way when my first batch turned gray. Cook in batches with 1 inch between pieces for that perfect golden crust. 🔥

Skipping the Rest

After searing, resist cutting immediately. Let medallions rest 5 minutes under foil so juices redistribute. Slicing too soon sends all that flavor onto your cutting board, not your plate.

Under-seasoning the Meat

Don’t be shy with salt—use the full 1.5 tsp kosher salt for the whole fillet. Pork needs aggressive seasoning to stand up to the bold herb butter. I always taste the raw meat after seasoning to check.

Using Cold Butter

Your 6 tbsp unsalted butter must be softened for the herb butter to incorporate properly. Cold butter won’t blend with the herbs and garlic, leaving you with uneven flavor distribution.

Overcooking the Pork

Pull medallions at 145°F internal temperature—they’ll rise to 150°F while resting. Overcooking dries out pork fillet faster than any other cut. I use an instant-read thermometer for precision.

Neglecting the Fond

When building the sauce, scrape every browned bit from the pan—this is pure flavor. Use a wooden spoon and ½ cup white wine to deglaze thoroughly before adding other liquids. Those caramelized bits make the sauce sing. 💡
