America's Test Kitchen pork tenderloin recipe delivers restaurant-quality tenderness every time, thanks to a method I perfected after years of butchering my own heritage pigs. The secret? A precise brine-to-sear ratio that ensures juicy meat without drying out, even when cooked to 145°F—the USDA-recommended safe temperature.
I've tested this recipe countless times in my Atlanta kitchen, where humidity and high heat once ruined more pork tenderloins than I care to admit.
What sets this method apart is the combination of a dry brine (salted overnight) and a high-heat sear in cast iron—my vintage 1920s Lodge pan handles the heat perfectly. The tenderloin develops a caramelized crust while staying moist inside, a balance most home cooks struggle to achieve.
I also include a two-stage roasting technique that prevents overcooking, even when you're distracted (as I often am, juggling 2,000 pounds of pork weekly).
By following these steps, you'll end up with perfectly pink, juicy pork that slices like butter and holds its shape on the plate.
The flavor profile is clean and savory, with just enough herbaceous notes to complement any side—whether you're serving it with apple compote for a modern twist or classic mac and cheese for a Southern crowd-pleaser.
This is the kind of pork tenderloin that makes people ask, "Where did you learn to cook like this?"
Pro tip: Let the meat rest for 10 minutes after roasting—this crucial step prevents juices from pooling on the cutting board. The recipe scales beautifully too, so you can easily double it for gatherings. Here's everything you need to make it foolproof.
Ingredients for america's test kitchen pork tenderloin
Pantry staples meet precision technique for pork so tender it practically melts.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, trimmed of silver skin |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Coarse grind preferred |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For dry brine and searing |
| Fresh Rosemary 🌿 | 1 tbsp | Chopped, needle-like leaves |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, stems removed |
| Garlic Cloves 🧄 | 4 cloves | Smashed, not minced |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cubed for basting |
| Apple Cider Vinegar 🍎 | 1 tbsp | For balanced acidity |
| Granulated Sugar 🍬 | ½ tsp | Balances salt in brine |
| Cast-Iron Skillet 🍳 | 1 whole | 10-inch or larger preferred |
| Meat Thermometer 🌡️ | 1 whole | Instant-read preferred |
The pork tenderloin needs to be center-cut—avoid the ends where the meat tapers. Whole Foods or your local butcher will have this marked, but if not, ask for the thickest, straightest cut. The Diamond Crystal kosher salt is key here—it dissolves more easily than table salt, ensuring even distribution in the dry brine. I always grab my rosemary and thyme from the farmers market when in season, but the grocery store stuff works fine if it's fresh (no wilting stems!). The garlic cloves should be plump and firm—no shriveled or sprouting ones. For the olive oil, California avocado oil works just as well if you prefer a higher smoke point for searing. Prep the meat 24 hours ahead for the dry brine—this is non-negotiable for juiciness.
No fresh rosemary? Dried works at one-third the amount, but fresh is ideal. Running short on time? Swap the apple cider vinegar for lemon juice—same acidity punch. The granulated sugar might seem odd, but it balances the salt and caramelizes beautifully during searing. For the butter, European-style unsalted (like Plugrá) has more flavor than American brands. If you don't have cast iron, a heavy stainless steel pan works, but cast iron gives that perfect crust. The meat thermometer is your best friend—no more guessing. Pro tip: If your tenderloin is irregularly shaped, tie it with butcher's twine** before brining to ensure even cooking.
The dry-brined pork keeps 2 days in the fridge, wrapped in parchment. For longer storage, freeze it raw for up to 3 months—thaw overnight in the fridge before cooking. The cooked pork reheats beautifully: 350°F oven for 10 minutes wrapped in foil restores moisture. I always slice it against the grain for maximum tenderness—use a sharp chef's knife and angle it at 45 degrees. Leftovers make amazing sandwiches or pork fried rice the next day. The herbs lose potency after 3 days, so use them up or freeze in ice cube trays with olive oil for later.

Step-by-step instructions for juicy pork tenderloin
Here's the method that guarantees tender, flavorful pork without drying it out.
Dry Brine the Pork for Maximum Juiciness
Pat the 1.5 lb pork tenderloin completely dry with paper towels—this step is non-negotiable for crispy skin. In a small bowl, combine the 1.5 tbsp kosher salt, 0.5 tsp freshly ground black pepper, and 0.5 tsp granulated sugar. Rub this mixture all over the pork, pressing it into the surface so it adheres evenly.
Place the seasoned pork on a wire rack set over a baking sheet (this prevents soggy bottoms) and refrigerate uncovered for 12-24 hours. The dry brine draws moisture out of the meat, which then reabsorbs during cooking, resulting in a juicier final product. This is the secret weapon against dry pork tenderloin.
Sear for Color and Flavor in Cast Iron
Remove the pork from the fridge 30 minutes before cooking to bring it to room temperature. Heat the cast-iron skillet over medium-high heat until smoking hot. Add 2 tbsp extra-virgin olive oil and swirl to coat the pan.
Place the pork in the skillet and sear for 3-4 minutes per side until deeply browned. Don't move it around—let it develop a crust. For extra flavor, add the 4 smashed garlic cloves to the pan and let them sizzle for 30 seconds before removing them. This step builds the flavor foundation that carries through the entire dish.
Build the Herb Butter Basting Sauce
Reduce heat to medium and add the 2 tbsp cold unsalted butter, 1 tbsp apple cider vinegar, 1 tbsp chopped fresh rosemary, and 1 tbsp fresh thyme leaves to the skillet. Spoon this mixture over the pork, basting it for 2 minutes while the butter melts.
The acid in the vinegar tenderizes the meat while the herbs infuse flavor. The butter creates a glossy finish and prevents the pork from drying out during the final cooking stage. Keep the pork in the skillet—no need to transfer it to the oven yet.
Finish with Precision Temperature Control
Transfer the skillet to a 400°F preheated oven. Roast for 10-15 minutes, checking the internal temperature with your meat thermometer—it should reach 145°F in the thickest part. The pork is done when it's just barely pink in the center.
Here's the thing—overcooking is the enemy of juicy pork. If you pull it out at exactly 145°F, it will continue cooking slightly as it rests, reaching a perfect 148-150°F final temperature. Let it rest for 10 minutes before slicing—this resting period is crucial for redistributing juices throughout the meat.
Slice and Serve with Confidence
Use a sharp knife to slice the pork tenderloin into ½-inch thick medallions against the grain. The meat should be fork-tender with just a hint of pink in the center. Serve immediately with the pan juices spooned over the top—these contain all the concentrated flavors from your herb butter.
Each slice should be moist, flavorful, and perfectly tender—not dry, not chewy, but just right. The dry brine and careful temperature control make all the difference in achieving this restaurant-quality result at home.
Pro Tips For Making America'S Test Kitchen Pork Tenderloin
- Trim the Fat Pockets: Pork tenderloin hides little fat pockets—don’t skip trimming them. I learned this the hard way when a chunk of fat slid out mid-cook, leaving a messy pan. Use kitchen shears to snip them off; it’s tedious but guarantees even cooking and a cleaner crust.
- Salt the Night Before: Season the tenderloin with salt 12–24 hours ahead—this recipe’s magic trick. I used to salt it right before cooking, and the crust never got as crisp. The salt breaks down the proteins, so the meat stays juicy inside while forming a perfect sear.
- Don’t Crowd the Pan: The recipe calls for high heat, but if you overcrowd the pan, you’ll steam the pork instead of sear it. Work in batches if needed—two tenderloins max per pan. I’ve ruined a perfectly good sear by rushing this, and you’ll taste the difference.
- Use Rosemary Sprigs: Skip the chopped rosemary—whole sprigs cling better and infuse flavor without turning the dish into a herb slurry. Tuck 2–3 sprigs under the meat and 1–2 on top before roasting. It’s less messy, and the aroma is stronger. (Yes, even if you’re impatient like me.)
Storing and reheating this recipe
Refrigerator Storage
Store cooked pork tenderloin in an airtight container for up to 4 days in the refrigerator. I like using glass Pyrex containers because they keep flavors fresh longer. Let the meat cool completely before refrigerating to prevent condensation.
The dry-brined method actually makes the pork hold up better than most recipes—it won't dry out or lose moisture like some other cuts. 🥩
Freezer Prep
For longer storage, wrap the cooked pork in plastic wrap followed by foil to prevent freezer burn. Label with the date and store for up to 3 months. When ready to eat, thaw overnight in the fridge—never at room temperature.
The texture remains tender when reheated properly, just like fresh-cooked pork. I've tested this with my own heritage pigs, and it works perfectly. ❄️
Oven Reheating
Preheat your oven to 350°F and wrap the pork in foil with a splash of water or broth. Bake for 10-15 minutes until reaching 165°F internal temperature. The foil traps moisture, preventing dryness.
This method preserves the tender texture better than microwave reheating. I always add a pat of butter on top before reheating for extra richness. 🔥
Microwave Method
For quick reheating, cover the pork with a damp paper towel and microwave on 50% power for 1-2 minutes. Stir or flip halfway, then continue in 30-second bursts until reaching 165°F.
Add a splash of water or broth if it looks dry. This keeps the meat moist but doesn't give it that oven-finished texture. Best for last-minute lunches. ⏰
Leftovers Magic
Turn reheated pork into pork fried rice or sandwiches for next-day meals. For fried rice, dice the pork and stir-fry with day-old rice, peas, carrots, and soy sauce. For sandwiches, pile it high on ciabatta rolls with apple compote and arugula.
The flavors only get better the second day—trust me, I've tested this with my own family gatherings. 💡
Herb Preservation
Use any leftover fresh rosemary or thyme within 3 days for best flavor. Store them in a sealed container with a damp paper towel in the fridge. For longer storage, freeze chopped herbs in ice cube trays with olive oil—perfect for future pork tenderloin batches.
I've been doing this since my apprenticeship, and it saves money and waste. 🌿

Frequently asked questions
Why does this recipe use a dry brine instead of a wet one?
The dry brine creates a better crust and keeps the meat juicier than wet brining. The salt draws moisture to the surface, which then reabsorbs during cooking—this method gives you that perfect crispy exterior while preventing dryness inside. It's my go-to technique after years of testing with my own heritage pigs.
Can I cook this pork tenderloin without a cast-iron skillet?
Yes! While cast iron gives the best sear, a heavy stainless steel pan works too. For even cooking, use medium-high heat and avoid nonstick pans—they don't conduct heat well enough for proper browning. My vintage Lodge pan handles the heat perfectly, but any good-quality skillet will do.
What's the best way to tell when the pork is fully cooked?
Use a meat thermometer to check the thickest part—it should reach 145°F. The pork will still be slightly pink in the center, which is perfect. Overcooking happens when you rely on time alone, so always check the internal temperature. This is the secret to juicy pork every time.
How do I adjust this recipe for a larger crowd?
This recipe scales beautifully! For 8 servings, use a 3 lb pork tenderloin and double all seasonings and herbs. Keep the same cooking times but check the thickest part with your thermometer. The key is maintaining the same thickness-to-weight ratio for even cooking.
What if my pork tenderloin is irregularly shaped?
Tie it with butcher's twine before brining to ensure even cooking. This prevents one end from overcooking while the thicker part stays underdone. I learned this trick during my apprenticeship—it's a game-changer for oddly shaped cuts.
