Ingredients for america's test kitchen pork tenderloin
Precision-cut ingredients transform ordinary pork into restaurant-worthy perfection with crispy celery crowns and velvety gravy.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Tenderloin 🐖 | 1 ½ lb | Trimmed of silver skin, even thickness |
| Celery Stalks 🧅 | 4 whole | Thick, stringless, cut into 1/2-inch slices |
| All-Purpose Flour 🌾 | ¼ cup | For dredging celery crowns |
| Unsalted Butter 🧈 | 2 tbsp | European-style preferred for flavor |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for high-heat searing |
| Fresh Thyme Leaves 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Rosemary 🌿 | ½ oz | Finely chopped, fresh preferred |
| Shallots 🧅 | 2 whole | Minced, or sub with red onion |
| Dijon Mustard 🍯 | 1 tbsp | High-quality, for gravy depth |
| Chicken Stock 💧 | 1 ½ cups | Homemade or high-quality store-bought |
| Dry Sherry 🍷 | ¼ cup | Sub with white wine if unavailable |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning, not iodized |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns preferred |
| Granulated Sugar 🍬 | ½ tsp | Balances acidity in gravy |
The pork tenderloin must be trimmed of silver skin and cut to even thickness for consistent cooking—Costco or Whole Foods carry high-quality cuts with minimal fat. For celery crowns, select thick, stringless stalks (avoid the thin, fibrous ones) from the produce section of a specialty market like Trader Joe's or Eataly, where quality is more consistent. Fresh herbs are non-negotiable here: Penzeys Spices or local farmers' markets offer the most aromatic thyme and rosemary. The shallots add depth—substitute with red onion** if unavailable, but mincing is key for even distribution.
No dry sherry? White wine or apple cider works in a pinch, but the acidity will differ slightly. The Dijon mustard should be smooth, not grainy—Maille or Amora are reliable brands. For the celery crowns, flour dredging is critical—skip the baking powder or cornstarch; it alters texture. If you can't find chicken stock, vegetable stock with a splash of soy sauce mimics the umami. The sugar in the gravy balances the acidity—omit if using tart wine**—but it's essential for harmony when using sherry.
Pork tenderloin keeps best 2 days refrigerated in an airtight container, while celery crowns should be prepped and refrigerated separately (they crisp best when fresh). The gravy reheats beautifully—simmer gently to prevent skin formation, and store in a sealed jar for up to 5 days. For make-ahead convenience, trim and portion the pork, then refrigerate until ready to sear—this ensures even cooking every time. Herbs can be chopped ahead and stored in the fridge for 3 days, though freshness fades faster than flavor.

Step-by-step instructions for crispy pork tenderloin with herb gravy
Precision technique delivers perfect results every time—crispy exterior, tender interior, and velvety gravy.
Prepare the Pork Tenderloin for Even Cooking
Pat the 1.5 lb pork tenderloin dry with paper towels, removing all visible moisture. This step is critical—wet surfaces prevent proper browning. Trim any remaining silver skin and use a sharp knife to make a shallow crosshatch pattern on the surface. This creates more surface area for flavor absorption and helps prevent curling during cooking.
In a small bowl, combine 1.5 tsp Diamond Crystal kosher salt, 0.5 tsp freshly ground black pepper, 0.25 cup finely chopped fresh thyme leaves, and 0.5 oz finely chopped fresh rosemary. Rub this mixture evenly over the pork, pressing it into the crosshatched surface. Let it sit at room temperature for 30 minutes while you prepare the celery crowns. This resting period ensures even cooking from edge to center.
Create Crispy Celery Crowns
Cut the 4 whole celery stalks lengthwise into quarters, then slice each quarter into ½-inch thick rounds. You should have about 16 pieces total. Pat these dry with paper towels—moisture is the enemy of crispiness. In a shallow bowl, combine 0.25 cup all-purpose flour with 0.5 tsp kosher salt and 0.25 tsp black pepper. Toss the celery pieces in this mixture until evenly coated.
Heat 2 tbsp olive oil in a large skillet over medium-high heat until shimmering. Working in batches, add the coated celery and cook for 2-3 minutes per side until golden brown and crispy. Transfer to a paper towel-lined plate to drain excess oil. Keep warm while you prepare the pork. The celery should maintain its crunch when served—if they soften, cook them again briefly before plating.
Sear and Roast the Pork to Perfect Doneness
Heat 2 tbsp unsalted butter in the same skillet over medium-high heat until foaming. Add the seasoned pork tenderloin and sear for 2 minutes per side until deep golden brown all over. Remove the pork and set aside. The butter should be nutty-smelling and have small browned bits stuck to the bottom—this is flavor you'll incorporate into the gravy.
Transfer the pork to a wire rack set over a baking sheet and roast in a 400°F oven for 10-12 minutes (for medium-rare) or until the internal temperature reaches 145°F on a meat thermometer. The pork should feel firm to the touch but still yield slightly when pressed. Let it rest for 10 minutes before slicing—this resting period is crucial for juicy results. If you cut it too soon, precious juices will escape onto your cutting board.
Make the Herb-Infused Gravy
Return the skillet with browned bits to medium heat. Add 2 minced shallots and cook for 1 minute until softened. Pour in 0.25 cup dry sherry and scrape up all the browned bits from the bottom with a wooden spoon. Let it simmer for 2 minutes until reduced by half. This deglazing step captures all the flavor from the searing process.
Add 1 tbsp Dijon mustard, 1.5 cups chicken stock, and 0.5 tsp granulated sugar. Bring to a simmer and let it cook for 5-6 minutes until slightly thickened. The sugar balances the acidity from the sherry, while the mustard adds depth. Season with additional salt and pepper if needed. The gravy should coat the back of a spoon but still be pourable—if it's too thick, whisk in 1-2 tablespoons of water to reach the perfect consistency.
Plate and Serve with Crispy Celery Crowns
Slice the rested pork into ½-inch thick medallions and arrange 2-3 pieces per serving on warmed plates. Ladle the herb-infused gravy generously over the pork, coating it completely. Place 4 crispy celery crowns on each plate, arranging them fan-style around the pork. The contrast of crispy celery with tender pork and velvety gravy creates a perfect balance of textures and flavors.
Garnish with additional chopped thyme and rosemary if desired. Serve immediately while the celery remains crisp and the pork stays warm. The gravy should cling beautifully to both the pork and celery, creating each bite into a harmonious experience. For an extra touch, pass additional gravy at the table for those who want more.
Pro Tips For Making America'S Test Kitchen Pork Tenderloin
- USE A MEAT THERMOMETER: The ATK recipe’s pork needs to hit 145°F—no guessing. I used to pull it at 140°F and always ended up with dry meat. The thermometer’s $20 well spent, especially for a lean cut like tenderloin.
- SALT THE PORK 40 MINUTES EARLY: This isn’t just seasoning—it’s about flavor penetration. Sprinkle kosher salt (about 1 tsp per pound) and let it sit uncovered in the fridge. I skipped this once and the crust tasted flat.
- BROWN THE FLOURED PORK FIRST: Don’t rush the sear—let the butter and olive oil pool in the pan until it’s smoking hot. The pork should sizzle for 2 minutes per side before adding celery. That crust is what holds the sauce together.
- REST IT UNDER FOIL: After roasting, tent the pork with foil and let it sit for 5–10 minutes. I know, I know—you want to cut into it immediately. But skipping this step means juices running out, and that’s the one thing you can’t fix.
Essential equipment for america's test kitchen pork tenderloin
Precision Skillet
You'll need a 12-inch cast iron skillet—I swear by my Lodge Pre-Seasoned with a well-seasoned surface for perfect searing. The flat bottom ensures even heat distribution, which is critical for that golden-brown crust on both the pork and celery crowns.
If you don't own cast iron, a heavy stainless steel skillet like All-Clad works too, but preheat it for 5 minutes to mimic cast iron's heat retention. 🔥
Meat Thermometer
Never guess doneness with pork—instant-read thermometers are non-negotiable. I use the ThermoWorks Smoke (it's my go-to for all meats) because it's fast and accurate. Insert it into the thickest part of the tenderloin—145°F is your target for medium-rare.
For thicker cuts, aim for 150°F to ensure even doneness throughout. A cheap probe thermometer might give false readings, so invest in quality.
Wire Rack & Baking Sheet
A wire rack placed over a baking sheet is essential for even airflow during roasting. This prevents the pork from steaming in its juices, which would make the exterior soggy. I use my Ozeri Snap-N-Lock rack—it's sturdy and fits perfectly in my All-Clad stainless steel half-sheet pan.
If you don't have one, a cooling rack from the bakery section works in a pinch. Just make sure it's stable so the pork doesn't wobble during roasting.
Tongs & Wooden Spoon
Tongs are your best friend for flipping the pork—OXO Good Grips have the best reach and grip. Avoid forks, which pierce the meat and cause juices to escape. For the gravy, a wooden spoon (like Lodge's with the curved handle) is perfect for scraping up those flavorful browned bits from the skillet. Metal spoons can scratch your cast iron, so wooden is ideal for deglazing.
Fine-Mesh Strainer
When straining the gravy, a fine-mesh strainer (like OXO Good Grips) ensures a smooth, silky texture without any herb bits. If you're short on time, a cheesecloth-lined colander works too—just double it up for extra filtration.
Skimping here can leave your gravy grainy, which ruins the luxurious mouthfeel. I also keep a small ladle nearby to transfer the strained gravy back to the pot for reheating.
Sharp Chef's Knife
A sharp 8-inch chef's knife (I use Wüsthof's Classic) is crucial for even slicing the pork tenderloin into ½-inch medallions. Dull knives crush the meat, leading to uneven cooking. For the celery crowns, a sharp knife makes quick work of the ½-inch slices—no struggle required.
If your knife isn't sharp, hone it with a Whetstone before starting. A dull knife is more dangerous than a sharp one, trust me.

Frequently asked questions about america's Test Kitchen-style pork tenderloin
Why does the recipe call for resting the pork before slicing?
Resting the pork for 10 minutes after cooking allows the juices to redistribute evenly throughout the meat. If you slice it too soon, those juices will escape onto your cutting board, leaving you with dry, tough slices. This step is especially important for pork tenderloin, which can dry out quickly if not handled properly.
Can I substitute dry sherry with another ingredient?
Yes! If you don't have dry sherry, use white wine or apple cider in equal amounts. The acidity will differ slightly, but it will still work well for deglazing the pan. For a non-alcoholic option, try apple juice or white grape juice—just reduce the sugar in the gravy by ¼ tsp to balance the sweetness.
How do I fix pork that's overcooked and dry?
Unfortunately, overcooked pork can't be fully revived, but you can salvage it by shredding it and using it in dishes like tacos, pasta, or fried rice. For future success, always use a meat thermometer and remove the pork from the oven when it reaches 145°F (medium-rare). If you prefer well-done pork, aim for 150°F and slice it thinner to compensate for moisture loss.
What's the best way to reheat the leftovers?
Reheat pork tenderloin leftovers gently in a skillet over low heat with a splash of chicken stock or water to keep them moist. Avoid the microwave, as it can make the meat rubbery. For the gravy, reheat it on the stovetop over medium-low heat, stirring constantly to prevent skin formation. Store leftovers in an airtight container for up to 3 days in the refrigerator.
Can I make this recipe ahead of time?
Prep the pork by trimming and seasoning it up to 24 hours ahead, then refrigerate uncovered for 30 minutes before cooking. The celery crowns should be prepped and refrigerated separately (they crisp best when fresh). Assemble the dish just before serving to maintain the celery's crunch and the pork's juiciness. The gravy can be made a day ahead and reheated gently.
