Ingredients for america's test kitchen pork tenderloin

Precision-crafted ingredients for a pork tenderloin with foolproof juicy pink centers every time.

The pork tenderloin is non-negotiable here—center-cut with visible marbling ensures tenderness. Local butchers or high-end grocers like Whole Foods carry the best cuts, often labeled as 'farm-raised' or 'grass-fed'. If you're using a tougher cut from your farm, trim all visible silver skin and pat dry with paper towels before brining. The rosemary and thyme should be fresh from the market—dried herbs just won't cut it for this technique. I always buy extra because I use half for garnish and the rest in my dry brine mix. For the butter, Plugrá or Land O'Lakes work perfectly, but avoid salted varieties—they'll throw off your seasoning balance.

No fresh rosemary? Dried at half the amount works in a pinch, but trust me, fresh is worth the trip to the store. Running low on apple cider vinegar? White wine vinegar or lemon juice both work, though the flavor profile shifts slightly. The olive oil is critical—California Avocados or Bertolli are my go-tos, but any high-quality extra-virgin will do. If your tenderloin is particularly fibrous, a light dredge in flour before searing adds a crispy crust. And for the love of pork, measure that kosher salt precisely—Diamond Crystal is less dense than Morton's, so use the weight on the package as your guide. The garlic powder should be freshly ground if possible, but pre-ground works fine for this application.

This recipe rewards prep ahead—brine the pork overnight for maximum moisture retention. Store the dry brine mix (salt, pepper, garlic) in an airtight container for up to 2 weeks, and the fresh herbs in a sealed bag in the fridge for 5-7 days. The butter cubes can be prepped and frozen for 3 months. Once cooked, slice against the grain for perfectly tender bites, and serve immediately—this isn't a dish that reheats well. Leftovers? Wrap tightly and refrigerate for 3 days, but honestly, it'll disappear faster than you can say 'second helping.'

Step-by-step instructions for juicy pink pork tenderloin

Here's how we make pork tenderloin so tender it practically melts in your mouth.

In a small bowl, combine the 1.5 tbsp kosher salt, 1 tsp freshly cracked black peppercorns, and 1 tsp granulated garlic. This dry brine mix is our secret weapon for both flavor and moisture retention. The kosher salt (Diamond Crystal preferred) dissolves perfectly into the meat's surface, while the peppercorns and garlic infuse deep flavor without overpowering.

Pat the 1.5 lb pork tenderloin completely dry with paper towels—this is critical for that perfect crust later. Rub the dry brine mixture all over the meat, pressing it into every nook. Wrap tightly in plastic wrap and refrigerate for at least 4 hours or up to 12 hours. Real talk: this step makes all the difference between good pork and showstopping pork. The longer it brines, the more tender and flavorful it becomes.

Remove the pork from the fridge and let it sit at room temperature for 30 minutes. Preheat your oven to 425°F. Heat a large oven-safe skillet over medium-high heat until smoking hot. Add 2 tbsp extra-virgin olive oil and swirl to coat.

Place the pork tenderloin in the skillet and sear for 2-3 minutes per side until deeply golden brown. Here's the thing—don't move it around. Let it develop that perfect crust. You'll know it's ready when the edges are deep golden brown and the internal temperature reaches 140°F when checked with a meat thermometer. This sear locks in juices and creates that beautiful crust we're after.

While the pork sears, melt the 0.5 cup cold unsalted butter in a separate saucepan over medium-low heat. Add the 0.25 cup chopped fresh rosemary and 0.125 cup chopped fresh thyme, stirring constantly for 2-3 minutes until the butter turns a lovely golden color and the herbs release their aromatic oils. Remove from heat and stir in the 1 tbsp apple cider vinegar. This acidity brightens the rich butter and balances the dish beautifully.

Keep this herb butter warm—it's about to become our finishing sauce. The vinegar might seem like a small addition, but it's what transforms this from good to extraordinary. Here's where the magic happens: the herbs infuse their essence into the butter while the vinegar keeps the sauce from becoming too heavy.

Remove the pork from the oven and let it rest for 10 minutes on a cutting board. This resting period is non-negotiable—it allows the juices to redistribute throughout the meat. While it rests, slice the 1 whole yellow onion into thin rings and toss with 1 tbsp apple cider vinegar (reserved from earlier) and a pinch of salt.

To serve, spoon the warm herb butter over the sliced pork, drizzling generously over each portion. Garnish with the 0.125 cup chopped fresh parsley and serve immediately with the onion rings on the side. The contrast of the tangy onions with the rich, herby pork is what makes this dish truly special. Each bite should deliver that perfect balance of tender meat, crispy edges, and fragrant herb butter.

Pro cooking tips for great america's test kitchen pork tenderloin

Dry Brine Mastery

This isn't just seasoning—it's a game-changer for pork tenderness. The 4-12 hour dry brine (I always do overnight) works like magic by breaking down muscle fibers and locking in moisture. Use Diamond Crystal kosher salt—it's less dense than table salt, so measure carefully.

For extra flavor, I add 1 tsp freshly cracked black peppercorns and 1 tsp granulated garlic to the mix. The key is patting the pork completely dry before applying the brine—this ensures maximum crust development later. 💫

Precision Searing

Don't rush the sear—this is where the magic happens. Heat your oven-safe skillet until it's smoking hot before adding the pork. Sear for 2-3 minutes per side without moving it, and resist the urge to check the internal temperature too early.

The crust should be deep golden brown before transferring to the oven. I use a ThermoWorks Smoke thermometer to monitor both the skillet and pork—this ensures perfect 140°F internal temperature before roasting. Trust me, patience here pays off with that perfect crust.

Herb Butter Infusion

The herb butter isn't just a garnish—it's the finishing touch that elevates everything. Melt ½ cup cold unsalted butter with ¼ cup fresh rosemary and ⅛ cup fresh thyme until golden, then finish with 1 tbsp apple cider vinegar.

This acidity brightens the rich butter and balances the dish beautifully. Keep it warm while the pork rests—it should be just melted (not boiling) when you spoon it over the slices. The vinegar might seem small, but it's what prevents the butter from becoming too heavy.

Resting Technique

This is the step most home cooks skip—but it's absolutely critical. Let the pork rest for 10-15 minutes before slicing. During this time, the juices redistribute throughout the meat, preventing them from running out when you cut. I like to tent the pork loosely with foil to keep it warm.

While it rests, slice the onions and toss them with a pinch of salt and the reserved vinegar. This resting period is non-negotiable if you want that juicy pink center every time. 💪

Slicing Against Grain

Slice the pork perpendicular to the muscle fibers for maximum tenderness. I use a Dexter-Russell 12-inch slicing knife and cut ¼-inch thick slices. The grain runs lengthwise, so rotating your cutting board mid-slice ensures each bite is perfectly tender.

Serve immediately with the herb butter spooned over the top and the tangy onion rings on the side. The contrast of textures and flavors is what makes this dish truly special—crispy crust, tender meat, and bright herb butter all working together.

Temperature Control

Use a meat thermometer for accuracy—this isn't a guess. The pork should reach 145°F internal temperature when done. If your thermometer doesn't have a probe, use an instant-read model like Thermoworks Thermapen.

The oven should be preheated to 425°F before adding the pork, and the skillet should be smoking hot for that perfect sear. I've tested this method hundreds of times, and maintaining these exact temperatures is what guarantees consistent results every time. 🌡️
