Ingredients for america's test kitchen pork tenderloin
Precision-crafted ingredients unlock the secret to restaurant-quality pork tenderloin at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Center-cut, trimmed of silver skin |
| Kosher Salt 🧂 | 1 tbsp | Diamond Crystal preferred, coarse grain |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns preferred |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cut into 4 pieces |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | High smoke point preferred |
| Fresh Rosemary 🌿 | 1 sprig | Thin stems removed, leaves chopped |
| Fresh Thyme 🌿 | 1 sprig | Leaves only, finely chopped |
| Garlic Cloves 🧄 | 2 cloves | Smashed, not minced |
| Apple Cider Vinegar 🍎 | 1 tbsp | Bragg preferred for acidity |
| Honey 🍯 | 1 tbsp | Wildflower preferred for depth |
| Vegetable Oil 🫒 | ¼ cup | For roasting, high smoke point |
| Fresh Lemon 🍋 | 1 whole | Juiced, for finishing |
The pork tenderloin cut is non-negotiable here—center-cut ensures consistent texture without connective tissue. Source from a trusted butcher or Whole Foods meat counter where they can cut it to your specifications. Look for a piece with even diameter and minimal surface silverskin. The butter should be cold and unsalted—European-style brands like Plugrá work best for high-fat content. Fresh herbs are critical; Trader Joe's sells pre-chopped rosemary and thyme in small containers that won't go to waste. For the honey, local wildflower adds complexity that commercial brands lack.
No fresh rosemary? Dried works at one-third the amount, but the flavor won't be as bright. Substitute olive oil with avocado oil for even higher smoke point during searing. The apple cider vinegar can be swapped for white wine vinegar, though Bragg's adds subtle sweetness. For the honey glaze, maple syrup is a 1:1 substitute if you're avoiding honey. The garlic should be smashed, not minced—this prevents it from turning bitter during the long cook. If your tenderloin is uneven, trim it to a uniform shape before seasoning to ensure even cooking.
Butter and herbs can be prepped 1 day ahead and stored in airtight containers. The tenderloin itself should rest uncovered on a wire rack for 30-60 minutes before cooking to promote even browning. Leftover pork reheats beautifully—4-5 days in the fridge or 3 months frozen when wrapped tightly in butcher paper. For make-ahead convenience, marinate the pork overnight in the honey-vinegar mixture, then pat dry before cooking. The crust will be less perfect but still delicious.

Step-by-step instructions for america's Test Kitchen pork tenderloin recipe
This method delivers perfectly tender, juicy pork with a clockwork sear that locks in moisture every time.
Prepare the Pork Tenderloin for Optimal Cooking
Pat the 1.5 lb pork tenderloin completely dry with paper towels, removing any surface moisture. This step is critical—wet surfaces prevent proper browning and can lead to steaming instead of searing. Using a sharp boning knife, trim off any silver skin or excess fat, leaving a clean surface for the seasoning to adhere.
Place the trimmed pork on a plate and season generously with 1 tbsp kosher salt and 0.5 tsp freshly ground black pepper. I like to press the seasoning firmly into the meat so it penetrates slightly. Let it sit at room temperature for 30 minutes before cooking. This allows the meat to cook more evenly and prevents chilling the pan when it hits the hot surface.
Create the Perfect Sear with Butter and Oil
Heat a large oven-safe skillet over medium-high heat until it's very hot—you should see a slight shimmer when you wave your hand above it. Add 1 tbsp extra-virgin olive oil and swirl to coat the pan evenly. Then add the 2 tbsp unsalted butter, cut into pieces, and let it melt completely, creating a thin, even layer of fat.
Carefully place the pork tenderloin in the skillet, fat-side down if applicable. Cook undisturbed for 4-5 minutes until a deep golden brown crust forms. This initial sear is what creates the "clockwork" moisture lock—don't rush it. You'll know it's ready when the edges release easily from the pan and the internal temperature reaches 145°F on an instant-read thermometer.
Build Flavor with Aromatics and Acid
Remove the pork from the skillet and set it aside on a plate. In the same skillet (with all those flavorful browned bits still clinging), add the 2 smashed garlic cloves, 1 sprig chopped fresh rosemary, and 1 sprig chopped fresh thyme. Cook for 30 seconds until fragrant, stirring constantly to prevent burning. This quick cooking preserves their delicate flavors.
Pour in the 1 tbsp apple cider vinegar and 1 tbsp honey, scraping up any browned bits from the bottom of the pan. Let this mixture simmer for 1-2 minutes until slightly reduced and syrupy. The acidity of the vinegar helps tenderize the meat further while the honey adds a subtle sweetness that balances the savory flavors.
Finish with a High-Heat Roast
Return the pork to the skillet, spooning the aromatic vinegar-honey mixture over the top. Transfer the skillet to a preheated 425°F oven and roast for 10-12 minutes, or until the internal temperature reaches 145°F and the pork is just barely pink in the center. The high heat ensures carryover cooking that brings the temperature up to a safe 150°F while maintaining moisture.
During this time, you'll notice the pork developing a beautiful caramelized crust. This is your signal that the clockwork sear is working—juices are being locked in rather than escaping. Remove from the oven and let it rest for 10 minutes before slicing. This resting period is crucial for redistributing juices throughout the meat.
Serve with Lemon and Pan Sauce
While the pork rests, juice the 1 whole fresh lemon and strain out any seeds. Stir the lemon juice into the pan sauce, then drizzle it over the sliced pork. The bright acidity cuts through the richness, enhancing all the flavors. For an extra touch, you can mount the slices on a platter with a few sprigs of fresh rosemary for garnish.
The finished pork should be perfectly tender with a juicy interior and a crisp, caramelized exterior. Each slice should hold its shape without falling apart, and the pan sauce should coat the meat with a glossy sheen. Serve immediately with your choice of sides to enjoy this restaurant-quality dish at home.
Pro Tips For Making America'S Test Kitchen Pork Tenderloin
- USE A MEAT THERMOMETER: The ATK recipe calls for medium-rare (130°F internal temp), but I’ve seen people pull pork at 140°F and end up with dry meat. A cheap instant-read thermometer solves this—no more guessing or overcooking. Stick it in the thickest part, and when it hits 130°F, that’s your cue to rest it.
- SALT THE PORK 40 MINUTES EARLY: This isn’t just seasoning—it’s about flavor penetration. The recipe says to salt before cooking, but I learned the hard way that 40 minutes ahead (even in the fridge) gives the salt time to work its magic. Skip this, and you’ll wonder why your pork tastes bland, no matter how much butter you slather on later.
- DON’T SKIP THE BUTTER BATH: The ATK method finishes the pork in a pool of melted butter, but I’ve seen people rush this step by just tossing the meat in a warm pan. Instead, pour that rendered butter back into the pan, let it foam and reduce slightly, then baste the pork in it. That golden crust? It’s worth the extra 30 seconds.
- LET IT REST—NO EXCUSES: I know, I know—you’re hungry, and the pork looks perfect. But cutting into it too soon means juices pooling on your plate instead of your fork. The recipe says 5 minutes, but give it a solid 10 under foil. Your knife will thank you, and so will your taste buds.
Pro cooking tips for perfect results
Precision Searing
That initial sear is where the magic happens—don't skimp on time or temperature. Heat your oven-safe skillet over medium-high heat until it's screaming hot, then add the 1 tbsp olive oil and 2 tbsp cold butter.
The butter should foam and sizzle before you add the pork. I swear by this technique because the high heat creates the Maillard reaction while the butter bastes the meat simultaneously, locking in moisture. 🔥
Room Temperature Prep
Never cook pork straight from the fridge—it chills your pan and creates uneven cooking. Let your 1.5 lb tenderloin sit at room temperature for 30 minutes before searing.
This simple step ensures even cooking throughout. I've seen home cooks skip this, and the results? Dry, unevenly cooked meat that's far from restaurant quality.
Thermometer Accuracy
An instant-read thermometer isn't optional—it's essential. Pork should reach 145°F internal temperature (measured in the thickest part). I use a ThermoWorks Smoke because it's fast and reliable.
The 10-minute rest after cooking is just as critical—it lets juices redistribute, ensuring each slice stays moist. Without this step, your pork will be dry and disappointing.
Butter Fat Ratio
Use 2 tbsp unsalted butter for every 1.5 lb pork tenderloin. The fat acts as a natural basting agent during cooking, creating a glossy crust while keeping the interior juicy.
I've tested this ratio dozens of times—it's the sweet spot between flavor development and moisture retention. Don't substitute with oil-only; the butter adds richness and helps create that perfect crust.
Acidic Balance
The 1 tbsp apple cider vinegar and 1 tbsp honey mixture is non-negotiable for tenderizing and balancing flavors. The acid breaks down muscle fibers slightly, while the honey adds depth.
I like to simmer this mixture for 1-2 minutes to reduce it slightly before spooning it over the pork. This creates a glossy finish that clings beautifully to each slice.
Oven Finish Secret
Transferring the skillet to a 425°F oven for the final 10-12 minutes ensures even cooking without over-searing. The residual heat in the skillet maintains the crust while the oven finishes the pork gently.
I've found that this two-stage cooking method—sear first, then oven finish—delivers the most consistent results with minimal effort. 💫

Frequently asked questions
Why does America's Test Kitchen recommend resting pork tenderloin?
Resting for 10 minutes after cooking is crucial because pork's muscle fibers tighten during cooking, pushing juices toward the center. When you slice immediately, those juices escape, leaving dry meat. The rest period lets them redistribute, ensuring each slice stays moist and flavorful. This simple step transforms good pork into exceptional pork.
Can I cook pork tenderloin without an instant-read thermometer?
While challenging, you can estimate doneness by cutting into the thickest part—the center should look just barely pink (145°F) with clear juices. For visual cues, aim for 10-12 minutes in a 425°F oven after searing. However, a thermometer guarantees perfect results every time, especially for beginners.
What's the best way to store leftover pork tenderloin?
Wrap cooled slices tightly in plastic wrap or store in an airtight container. Refrigerated pork stays fresh for 4-5 days and reheats beautifully in a skillet with a splash of water or broth. For longer storage, freeze for up to 3 months—thaw overnight in the fridge before reheating to preserve texture.
How do I adjust this recipe for thicker or thinner tenderloins?
For every 1-inch difference in thickness, add or subtract 2-3 minutes from oven time. A 2-inch thick tenderloin may need 15-17 minutes total, while a 1-inch piece cooks in 8-10 minutes. Always use a thermometer to verify 145°F internal temperature, regardless of size.
What's the secret to getting that perfect caramelized crust?
The crust comes from three key elements: hot pan (medium-high heat until shimmering), butter fat (2 tbsp cold butter basting the meat), and undisturbed cooking (4-5 minutes without moving). The butter's milk solids brown beautifully while basting, creating that glossy, crisp exterior we all crave.
