Ingredients for america's test kitchen pork tenderloin
Science-backed ingredients for restaurant-quality pork tenderloin—no dryness, just melt-in-your-mouth perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🥩 | 1 ½ lb | Bone-in or boneless, trimmed |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Coarsely cracked |
| Fresh Thyme Leaves 🌿 | ½ tsp | Stems removed |
| Fresh Rosemary Sprigs 🌿 | 2 whole | Leaves stripped |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For searing |
| Water 💧 | 1 cup | For brining |
| Ice Cubes ❄️ | 1 cup | For brine temperature |
| Meat Thermometer 📏 | 1 whole | Instant-read preferred |
The pork tenderloin is the star, so bone-in cuts add flavor and moisture—skip the boneless if you can find it. Costco or Whole Foods usually carry premium cuts with good marbling. Look for tenderloins that are bright pink, not grayish, and have a firm but slightly springy texture. If your cut is uneven, trim it to an even thickness for consistent cooking. The brining technique here is key—it's a 30-minute soak, not a full night, so don't skip it even if you're short on time. The salt and ice combo ensures the brine stays cold enough to work its magic without over-shrinking the meat.
No fresh thyme or rosemary? Dried works at one-third the amount, but fresh has that bright, herbal punch. Running out of olive oil? Avocado oil or grapeseed oil sear just as well—just don't use butter, it burns too easily. The meat thermometer is non-negotiable here—instant-read models from Amazon are reliable and affordable. If you don't have one, test for doneness by cutting into the thickest part (it should feel firm but yield slightly to pressure). The Kosher salt matters too—Diamond Crystal dissolves better than Morton's, so if that's all you've got, use a pinch more. And yes, you can use boneless cuts if that's what's available, but bone-in stays juicier longer.
Brined pork keeps 2 days in the fridge if stored in an airtight container with a paper towel pressed against the surface to absorb excess moisture. For longer storage, freeze for up to 3 months—thaw overnight in the fridge before cooking. The brining liquid can be reused for another batch if strained and refrigerated. Pro tip: Let the cooked pork rest 10 minutes before slicing—this ensures every bite stays juicy. Portion into meal prep containers for easy lunches, or freeze individual servings for quick dinners later.

Step-by-step instructions for america's Test Kitchen pork tenderloin
Here's the method that guarantees juicy, perfectly cooked pork every time—no dryness in sight.
Create the Perfect Brine for Maximum Juiciness
In a large bowl, combine the 1 cup water and 1 cup ice cubes to create an ice bath. This keeps the brine temperature at a consistent 35°F, which is ideal for tenderizing the meat without over-shrinking it. Dissolve the 1.5 tablespoons kosher salt into the ice water until fully combined—this creates a 3% brine solution that will penetrate the pork evenly.
Place the 1.5 lb pork tenderloin in a resealable plastic bag and submerge it completely in the brine. Seal the bag and gently massage the pork to ensure the brine coats all surfaces. Let it brine in the refrigerator for 30 minutes—this short time prevents the meat from becoming mushy while still delivering incredible moisture retention. The pork should feel slightly firmer after brining, and the surface will look slightly beaded with moisture.
Dry and Season for Optimal Browning
Remove the pork from the brine and rinse it briefly under cold water to remove excess salt. Then pat it thoroughly dry with paper towels—this step is non-negotiable for achieving a crispy exterior. I press down firmly on all sides, including the ends, until the surface looks matte and no moisture remains. Wet surfaces prevent proper browning and crust formation.
Strip the leaves from the 2 whole fresh rosemary sprigs and remove the stems from the 0.5 teaspoon fresh thyme leaves. Rub the herbs all over the pork, then sprinkle with 1 teaspoon freshly ground black pepper. The herbs add aromatic depth while the pepper enhances the crust's texture. Let the seasoned pork sit at room temperature for 15 minutes—this ensures even cooking and better heat penetration.
Sear for Color and Flavor Development
Heat a large skillet over medium-high heat until it's smoking hot. Add the 1 tablespoon extra-virgin olive oil and let it shimmer for 30 seconds. Place the pork in the skillet and sear for 2-3 minutes per side until it develops a deep golden-brown crust. The reason we sear first is that this locked-in moisture creates a barrier that prevents the pork from drying out during cooking.
I press down gently on the pork during the first minute of searing—this prevents it from curling and ensures even contact with the pan. You'll smell the herbs intensifying as they toast in the hot oil. Once the crust is set, transfer the pork to a plate and let it rest for 2 minutes before proceeding. This brief rest allows the surface to set slightly, making it easier to handle.
Roast to Perfect Doneness
Preheat your oven to 425°F. Place the seared pork on a wire rack set over a baking sheet—this allows hot air to circulate underneath for even cooking. Roast for 12-15 minutes, rotating the pan halfway through for uniform browning. The pork is done when a meat thermometer inserted into the thickest part reads 145°F—this ensures it's juicy and safe to eat.
Here's the thing—pork tenderloin can dry out quickly, so timing is everything. If you cut into it too early, the juices will run out. But when it hits 145°F, the meat will be tender, with just a hint of resistance when you press your finger into it. The exterior should be deep golden brown with crispy edges, while the interior remains juicy and pink.
Rest and Serve for Maximum Tenderness
Transfer the pork to a cutting board and tent loosely with aluminum foil. Let it rest for 10 minutes before slicing—this crucial step allows the juices to redistribute throughout the meat. If you skip this, you'll end up with dry slices. During the rest, the internal temperature will rise to about 150°F, which is ideal for serving.
Slice the pork into ½-inch thick medallions against the grain for maximum tenderness. The slices should be moist and flavorful, with a perfect balance of crispy exterior and juicy interior. Serve immediately with your favorite sides—this pork pairs beautifully with a honey-mustard glaze, roasted vegetables, or a fresh herb salad. The herbs and pepper will infuse the meat with layers of flavor that keep it interesting bite after bite.
Pro Tips For Making America'S Test Kitchen Pork Tenderloin
- SEAR HARD FIRST: America’s Test Kitchen swears by a deep sear, and for good reason—it builds flavor crust before the roast. Use a heavy skillet (cast iron if you’ve got it) and let it sit for 3-4 minutes per side until the bottom turns golden brown. I used to rush this, and the meat ended up tasting flat. High heat. Seriously, crank it up.
- TRIM THE FAT PATCHES: Pork tenderloin hides little pockets of fat that won’t render nicely. Grab a sharp knife and trim those spots before seasoning—it’s tedious, but it keeps the meat from steaming instead of browning. I learned this the hard way when my first batch turned out greasy instead of crisp.
- USE A MEAT THERMOMETER: The recipe calls for 145°F internal temp, but guessing leads to dry meat or undercooked pork. Invest in a cheap thermometer and pull it out before it hits 145°F—pork carries over heat, and you’ll end up with a perfect medium doneness. I skipped this once and regretted every bite.
- REST IT PROPERLY: Tent the pork with foil and let it rest for 10 minutes after roasting. Skipping this step means juices pooling on your cutting board instead of redistributing. Sounds weird, but it works: the meat stays moist, and slicing is cleaner. (Yes, even if you’re impatient like me.)
Best sauces and condiments for this recipe
Classic Mustard Sauce
My go-to sauce for this pork tenderloin is a simple Dijon mustard glaze that adds tangy brightness while complementing the herb crust. Mix 2 tablespoons Dijon mustard, 1 tablespoon honey, and 1 tablespoon apple cider vinegar in a small bowl.
Brush this onto the pork during the last 5 minutes of roasting—the acidity cuts through the richness while the honey adds subtle sweetness. For extra depth, whisk in 1 teaspoon fresh thyme leaves (strained after infusing) before brushing. 🌟
Herb Butter Baste
For a restaurant-worthy finish, melt ¼ cup unsalted butter with 1 minced garlic clove and 1 teaspoon chopped fresh rosemary in a small saucepan. Simmer for 2 minutes until fragrant, then strain out the herbs. Brush this butter generously over the pork during the last 3 minutes of roasting.
The butter bastes the meat, creating a golden, glossy finish while infusing it with aromatic herbs. I love this technique because it keeps the pork moist and adds a luxurious touch without overpowering the natural flavor.
Apple-Cider Reduction
This sauce works beautifully for fall gatherings and adds a touch of autumnal warmth. Simmer ½ cup apple cider with 1 tablespoon brown sugar and ½ teaspoon cinnamon in a small saucepan until reduced by half (5-7 minutes).
Strain out any sediment, then whisk in 1 tablespoon butter for richness. Drizzle over sliced pork or serve on the side for dipping. The acidity from the cider and warmth of the spices balance the pork's savory notes perfectly. 🍎
Garlic-Yogurt Sauce
A lighter option that pairs wonderfully with grilled pork tenderloin slices is this garlic-yogurt sauce. Mix ½ cup plain Greek yogurt with 1 minced garlic clove, 1 teaspoon lemon juice, and a pinch of salt. For extra flavor, stir in 1 teaspoon chopped fresh dill or mint.
This sauce adds a cool, creamy contrast to the warm pork and works especially well in summer months. It's also great for meal prep—store in an airtight container for up to 3 days in the refrigerator.
Spicy Honey Glaze
If you love a little heat, this spicy honey glaze is a game-changer. Combine 2 tablespoons honey, 1 tablespoon sriracha, and 1 teaspoon rice vinegar in a small saucepan. Simmer for 3 minutes until slightly thickened.
Brush this over the pork during the last 5 minutes of roasting or drizzle over sliced meat. The sweet heat balances beautifully with the pork's natural richness. I like to serve this with a side of cool cucumber salad to tame the spice. 🌶️
Pan Sauce Magic
Never waste those flavorful pan juices! After removing the pork, place the hot skillet over medium heat and add 2 tablespoons chicken broth or water. Scrape up any browned bits with a wooden spoon, then whisk in 1 tablespoon butter and 1 teaspoon fresh thyme.
Simmer for 1 minute** until slightly thickened. Pour this pan sauce over the sliced pork or use it to moisten any roasted vegetables on the side. This technique transforms simple ingredients into a rich, flavorful sauce with minimal effort.

Frequently asked questions
Why does this recipe use a 30-minute brine instead of a longer one?
Our 30-minute brine is the sweet spot for pork tenderloin—long enough to tenderize without making the meat mushy. Longer brines (like overnight) work for tougher cuts but can over-shrink lean pork like tenderloin. The ice water keeps the brine cold, ensuring even penetration while maintaining texture. This method delivers maximum juiciness without compromising the meat's natural firmness.
Can I cook pork tenderloin without a meat thermometer?
Yes, but it requires practice. For a 1.5 lb tenderloin, cook until the thickest part reaches 145°F—about 12-15 minutes at 425°F. A visual cue: The exterior should be deep golden brown with crisp edges, while the interior should feel slightly firm but yield to gentle pressure. Cut into the thickest part—juices should run clear, not pink or bloody. If unsure, always use a thermometer for perfect results.
What's the best way to slice pork tenderloin for maximum tenderness?
Slice against the grain into ½-inch thick medallions for the most tender texture. Look for the muscle fibers running lengthwise—cutting perpendicular to these shortens them, making each bite easier to chew. Use a sharp knife and slice quickly to prevent tearing. For even slices, trim the ends first to create parallel surfaces, then slice uniformly.
Can I make this ahead of time for a dinner party?
Cook the pork as directed, then chill it in an airtight container for up to 2 days. Reheat gently in a 350°F oven for 10-15 minutes until warmed through (165°F internal temp). For make-ahead prep, slice after cooking and store in meal prep containers. Reheat individual portions in a skillet with a splash of broth for extra moisture. Pro tip: Keep sauce separate until reheating to prevent sogginess.
What if my pork tenderloin is uneven in thickness?
Trim the thicker ends to match the thinnest section for even cooking. Aim for 1.25-inch thickness—this ensures the center reaches 145°F while the edges don't overcook. If you can't trim, place the thicker end on the wire rack first during roasting. For dramatic shape differences, butterfly the tenderloin (slice horizontally through the center) and pound to even thickness before seasoning. This creates a beautiful presentation with consistent doneness.
