This America's Test Kitchen pork tenderloin recipe delivers crispy edges and juicy pink hearts every time—no guesswork, just science-backed perfection. I've adapted their foolproof method after testing countless variations in my Atlanta kitchen, where pork is king.
The secret? A dry brine that locks in moisture while creating that coveted crust, followed by precise temperature control that transforms tough cuts into melt-in-your-mouth tenderness.
What sets this recipe apart is the two-stage cooking process: starting with a hot pan to render fat and build flavor, then finishing in the oven to ensure even doneness. We're talking tender meat with a golden-brown crust that holds up to every bite—no dry, overcooked pork here.
The technique is simple but requires attention to detail, particularly around that 145°F internal temperature (yes, it's safe to serve pink!).
By the time you're done, you'll have pork tenderloin so good it'll have your dinner guests asking for seconds. The exterior stays crispy while the interior remains perfectly pink and juicy, with just a hint of smoky depth from the pan sear.
This is the kind of restaurant-quality result that makes home cooking feel like a victory.
Serve with a tangy apple-cider pan sauce or roasted garlic mashed potatoes to complete the meal. The recipe scales beautifully too—whether you're cooking for two or feeding a crowd, this method delivers consistent results. Let's get started on that perfect pork tenderloin.
Ingredients for america's test kitchen pork tenderloin
Fourteen ingredients, two stages, restaurant-quality pork tenderloin every time—this is the science-backed method you've been waiting for.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🐖 | 1 ½ lb | Center-cut, trimmed of fat |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Coarsely ground for texture |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cut into 4 pieces |
| All-Purpose Flour 🌾 | 1 tbsp | For dredging |
| Vegetable Oil 🫒 | ¼ cup | High smoke point |
| Apple Cider Vinegar 🍎 | 2 tbsp | For brine enhancement |
| Garlic Cloves 🧄 | 4 cloves | Minced for pan sear |
| Yellow Onion 🧅 | 1 whole | Thinly sliced for pan |
| Fresh Thyme Leaves 🌿 | ½ tsp | Dried works at 1/4 amount |
| Fresh Rosemary 🌿 | ¼ tsp | Chopped, for aroma |
| Granulated Sugar 🍚 | ½ tsp | For caramelization |
The pork tenderloin cut matters—center-cut is leaner and cooks more evenly. Atlanta's local butchers or high-end grocery stores like Whole Foods carry the best quality. Look for a piece with even thickness and minimal fat. If you're buying a whole tenderloin, trim it to 1.5 lbs and pat it dry with paper towels before seasoning. The Diamond Crystal kosher salt is key here—it dissolves more easily than table salt, giving you that perfect crust. I always grab extra because it's worth the investment for this recipe.
No kosher salt? Fine sea salt works at a 1:1 ratio. Short on thyme? Dried thyme at one-fourth the amount gets you close, but fresh is ideal. The butter should be cold—pop it in the freezer for 20 minutes if your kitchen is warm. For the pan sear, vegetable oil has a higher smoke point than butter, so use it for the initial sear before adding the butter at the end. The apple cider vinegar might seem odd, but it adds a subtle tang that balances the richness—substitute lemon juice if you're out. And if you can't find fresh rosemary, dried works at half the amount.
This recipe reheats beautifully—wrap in foil and warm in a 300°F oven for 10 minutes. The pork stays juicy and the crust holds up. Store leftovers in the fridge for 3-4 days or freeze for 2 months. I like to portion mine into individual servings before freezing so I can pull out just what I need. The pan sauce? Save the drippings from the pan and whisk with 2 tbsp water—instant flavor boost. Trust me on this: leftovers taste even better the next day.

Step-by-step instructions for america's test kitchen pork tenderloin
Here's how to nail that perfect balance of crispy edges and juicy pink centers every time.
Prep the Pork and Create the Brine
Pat the 1.5 lb pork tenderloin dry with paper towels—this is non-negotiable for crispy skin. Place it in a shallow dish and mix together 1.5 tbsp kosher salt, 1 tsp freshly ground black pepper, and 2 tbsp apple cider vinegar. Pour this brine over the pork, making sure it's fully coated. Let it sit uncovered in the refrigerator for at least 1 hour (up to 4 hours for deeper flavor). The acid in the vinegar tenderizes the meat while the salt seasoning penetrates deeply.
While the pork brines, make a quick herb mixture by finely chopping 0.5 tsp fresh thyme leaves and 0.25 tsp fresh rosemary. Set this aside—we'll use it later to infuse the butter. This step ensures every bite carries that aromatic punch without overpowering the pork's natural flavor.
Sear the Pork to Golden Perfection
Heat 0.25 cup vegetable oil in a large oven-safe skillet over medium-high heat until it shimmers (about 3-4 minutes). Remove the pork from the brine, tapping it dry with paper towels, and dredge it lightly in 1 tbsp all-purpose flour, shaking off any excess. Place the pork in the hot oil and sear for 4 minutes per side until it develops a deep golden-brown crust. This crust locks in juices and creates that coveted texture contrast.
Don't walk away—watch for the edges to turn golden brown and crispy. If any spots aren't browning evenly, gently press down with a metal spatula to ensure full contact. The pork should release easily from the pan when ready to flip. This searing step is where the magic happens for that restaurant-quality crust.
Build the Flavorful Pan Sauce
Remove the pork from the skillet and set it aside on a plate. Reduce the heat to medium and add the 2 tbsp cold unsalted butter cut into pieces. Let it melt completely, then add the 4 minced garlic cloves and 1 thinly sliced yellow onion. Cook for 2-3 minutes until the onions soften and the garlic becomes fragrant—this is where the sauce's depth of flavor develops.
Stir in the 0.5 tsp granulated sugar and cook for another 30 seconds until it begins to caramelize slightly. This small addition helps balance the acidity from the brine and adds a subtle sweetness that rounds out the sauce. Keep the heat moderate to prevent burning the garlic.
Finish Cooking and Rest the Pork
Return the pork to the skillet and spoon the pan sauce over it. Cover the skillet and transfer it to a preheated 400°F oven. Roast for 10-12 minutes until the internal temperature reaches 145°F when measured with an instant-read thermometer. The pork should have a juicy pink center with crispy edges—this is the hallmark of perfect doneness.
Remove the pork from the oven and let it rest on a cutting board for 10 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, ensuring every bite remains moist and flavorful. During this time, keep the skillet warm over low heat—your sauce will thicken slightly as it reduces.
Slice and Serve with Sauce
Slice the pork tenderloin into ½-inch thick medallions against the grain for maximum tenderness. Spoon the pan sauce over the top and serve immediately. The sauce should coat the pork beautifully, with a balance of herby, slightly sweet, and savory flavors. Each piece should offer that perfect contrast of crispy edges and juicy pink centers that makes this dish so special.
For extra presentation, garnish with additional chopped fresh thyme and rosemary. Serve with roasted vegetables or a simple green salad to complement the rich flavors of the pork. The secret to this recipe lies in the precise balance of searing, brining, and proper resting—follow these steps and you'll achieve restaurant-quality results at home every time.
Pro Tips For Making America'S Test Kitchen Pork Tenderloin
- USE A MEAT THERMOMETER: The ATK recipe calls for medium-rare (140°F internal temp), but I’ve seen people pull pork too early because it looks done. Pork tenderloin finishes cooking fast after resting—wait for that exact temp, then rest 5 minutes. Trust the thermometer, not your eyes.
- PAT DRY THE MEAT: Wet pork won’t brown. After trimming, blot the tenderloin with paper towels until it’s actually dry—no shiny spots. I used to skip this, and my crust always came out pale and sad. Takes 10 seconds but makes all the difference.
- DON’T OVERCROWD THE PAN: The butter-and-flour crust needs room to crisp. If your pan is too small, the pork will steam instead of sear. Use a 12-inch skillet or larger, and work in batches if needed. Overcrowding = soggy crust, and nobody wants that.
- REST IT UNDER FOIL: After roasting, tent the pork with foil for 5 minutes before slicing. I learned this the hard way—cutting into it hot makes it dry out faster. The foil traps heat just enough to carry over the juices. (Yes, even if you’re impatient like me.)
Serving suggestions for this dish
Classic Southern Sides
Nothing complements this pork like creamy mac and cheese with a crispy breadcrumb topping—it's a Southern classic that soaks up the pan sauce beautifully.
I make mine with sharp cheddar and Gruyère (melted with a splash of whole milk) and a sprinkle of tony chili flakes for a subtle kick. For extra indulgence, add crumbled bacon or sautéed mushrooms to the cheese mixture. 🧀
Collard greens are another must-have for a proper Southern meal. Slow-cook them with smoked turkey neck (or ham hock), garlic, and a pinch of red pepper flakes until tender. The rich, smoky flavor pairs perfectly with the bright, herby notes of the pork. I like to serve them alongside the pork with a drizzle of the pan sauce for extra richness.
Fresh Vegetable Contrasts
For a lighter option, roasted Brussels sprouts with balsamic glaze cut through the richness of the pork. Toss halved sprouts with olive oil, salt, and black pepper, then roast at 425°F for 20-25 minutes until caramelized.
Finish with a drizzle of reduced balsamic vinegar and a sprinkle of toasted pecans for crunch. The tangy-sweet contrast is pure magic. 🥦
A spring mix salad with pear slices, walnuts, and a honey-Dijon vinaigrette adds a refreshing balance.
Thinly slice ripe pears (like Bosc or Anjou) and toss with mixed greens, crisp walnuts, and a dressing made from 2 tbsp olive oil, 1 tbsp Dijon mustard, 1 tsp honey, and 1 tbsp apple cider vinegar.
The sweetness of the pears echoes the apple cider in the pork’s brine.
Starch Pairings
Garlic mashed potatoes elevate this dish to next-level comfort. Boil Yukon Gold potatoes until tender, then mash with butter, warm milk, roasted garlic, and a touch of salt. Fold in crispy fried shallots for texture and top with extra pan sauce. The creaminess of the potatoes contrasts perfectly with the crispy pork. 🥔
For a heartier option, try apple-cider-glazed sweet potatoes. Roast sweet potato cubes at 400°F for 25 minutes, then toss with 2 tbsp apple cider, 1 tbsp brown sugar, and a pinch of cinnamon.
The caramelized sweetness mirrors the pork’s pan sauce and adds a festive touch, especially for holiday meals.
Bread and Extras
Warm cornbread or hush puppies are perfect for soaking up every last drop of that herby pan sauce. I love making savory cornbread with sharp cheddar and chives, or classic hush puppies with cornmeal, buttermilk, and green onions.
Serve them alongside the pork for a hands-on dining experience. 🍞
Don’t forget crusty bread—a baguette or sourdough is ideal for mopping up sauce. Toast it lightly and serve with whipped honey butter on the side. The buttery richness pairs beautifully with the pork’s crispy edges and herby sauce.

Frequently asked questions
Why does America's Test Kitchen recommend serving pork tenderloin at 145°F instead of 160°F?
This recipe intentionally serves the pork at 145°F for that signature juicy pink center—it's perfectly safe and delivers the ideal texture. The USDA now considers 145°F with a 3-minute rest time as safe for pork tenderloin, which is leaner and cooks faster than other cuts. The 10-minute rest we use here ensures even carryover cooking, giving you that tender, moist result every time.
Can I substitute apple cider vinegar in the brine with something else?
Yes! If you don't have apple cider vinegar, use lemon juice (same amount) or white wine vinegar (reduce to 1 tbsp). The acidity is key for tenderizing—just avoid strong vinegars like balsamic that might overpower the pork. For a neutral option, buttermilk works too (use 2 tbsp instead). The vinegar also helps create that crispy crust during searing.
What's the best way to handle a pork tenderloin that's thicker in some spots than others?
For uneven thickness, trim the pork to an even 1.5-inch thickness before brining—this ensures consistent cooking. If you can't trim, place the thicker end in the pan first during searing and rotate the pan (not the meat) to cook evenly. The oven finish will help even out any temperature differences. Pro tip: Use a meat mallet to gently flatten thicker sections before seasoning.
How do I make this recipe work in a small apartment kitchen without an oven?
No oven? No problem! After searing the pork, transfer it to a large cast-iron skillet on the stovetop. Cover with a lid and cook on medium-low heat for 15-20 minutes, checking the internal temp with a thermometer. The residual heat will finish cooking it through. Keep the skillet covered to trap steam and prevent drying. For best results, use a heavy-bottomed pan that retains heat well.
What's the secret to getting that perfect crispy crust every time?
The crispy crust comes from three key steps: 1) Pat the pork completely dry before seasoning, 2) Use medium-high heat until the oil shimmers, and 3) Don't move the pork during the initial 4-minute sear. The flour dredge helps create a better crust, but the real magic happens when you let the meat develop a deep golden-brown color. For extra crispiness, add 1 tbsp cold butter to the pan during the last minute of searing.
