Ingredients for america's test kitchen pork loin
Six ingredients transform simple pork loin into a restaurant-worthy masterpiece with crispy celery crown and velvety herb gravy.
| Ingredient | Amount | Notes |
|---|---|---|
| Center-Cut Pork Loin 🍖 | 3 lb | Bone-in, 1.5-inch thick cut |
| Kosher Salt 🧂 | ½ cup | Diamond Crystal preferred |
| Granulated Sugar 🍚 | ¼ cup | For brining solution |
| Ice Cold Water 💧 | 4 cups | For brine mixture |
| Celery Stalk 🧅 | 1 whole | Thinly sliced, for crown |
| All-Purpose Flour 🌾 | ½ cup | For breading crown |
| Panko Breadcrumbs 🍞 | ½ cup | Japanese-style preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for crown |
| Fresh Thyme Leaves 🌿 | ¼ cup | Chopped, for gravy |
| Fresh Rosemary 🌿 | 1 tbsp | Chopped, for gravy |
| Garlic Cloves 🧄 | 4 cloves | Minced, for gravy |
| Dry White Wine 🍷 | ½ cup | Sauvignon Blanc preferred |
| Beef Stock 🍲 | 2 cups | Low-sodium preferred |
| All-Purpose Flour 🌾 | 2 tbsp | For gravy thickening |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For searing pork |
The center-cut pork loin is non-negotiable—look for 1.5-inch thick cuts with visible fat cap for optimal moisture retention. Whole Foods or local butchers often carry premium cuts, but Costco provides excellent value for bulk purchases. Brining requires precision: Diamond Crystal kosher salt dissolves more easily than Morton's, preventing grainy texture. Measure the sugar precisely—too much sweetens the pork, too little leaves it bland. For the celery crown, organic celery from Trader Joe's ensures crispness without bitterness, and pre-slicing the stalk streamlines prep.
No kosher salt? Diamond Crystal kosher salt substitute works, but adjust to taste—it's 20% less sodium than table salt. Running short on white wine? Dry vermouth or apple cider vinegar mimics acidity, though wine adds depth. The gravy's herb blend demands freshness: dried thyme at half the amount works in a pinch, but fresh from the garden delivers superior aroma. For the celery crown, substitute panko with crushed cornflakes if unavailable—texture remains crispy. The beef stock? Homemade is ideal, but low-sodium store-bought suffices for convenience. Whole Foods organic stock adds richness without sodium overload.
Store the brined pork in its liquid for up to 24 hours in the fridge—never exceed this time to prevent over-salting. Celery crown components keep separately for 2 days: flour and breadcrumbs in airtight containers, butter chilled. The herb gravy freezes beautifully for 3 months—portion into ice cube trays for single servings. Reheat gravy gently to preserve texture, and rest the pork 15 minutes post-roasting for even juiciness. Leftovers reheat best at 350°F until internal temp reaches 145°F.

Step-by-step instructions for perfectly brined pork loin with celery crown
This method delivers a juicy, flavor-packed pork loin with an extraordinary celery crown crust.
Prepare the Brine and Season the Pork
In a large non-reactive container, combine the 4 cups ice cold water, 0.5 cup kosher salt, and 0.25 cup granulated sugar until fully dissolved. Submerge the 3 lb center-cut pork loin completely in the brine solution, ensuring it's fully covered. Refrigerate for 12 to 24 hours, turning the pork occasionally to ensure even brining.
The brine solution should remain ice cold throughout the process. This step ensures exceptional moisture retention and seasoning penetration. After brining, pat the pork dry thoroughly with paper towels, removing any excess moisture from the surface. This drying step is critical for achieving that perfect crust during searing.
Create the Celery Crown Breading
Thinly slice the 1 whole celery stalk into matchstick-sized pieces. In a mixing bowl, combine the sliced celery, 0.5 cup all-purpose flour, and 0.5 cup panko breadcrumbs. Add the 0.5 cup cold cubed unsalted butter and toss until the butter is evenly distributed and the mixture resembles coarse breadcrumbs.
This celery crown mixture should be dry enough to cling to the pork but not so wet that it falls apart. The cold butter helps create a crisp, flavorful crust while the celery adds a distinctive crunch and subtle sweetness. Keep this mixture at room temperature until ready to use.
Sear the Pork and Apply the Celery Crown
Heat a large oven-safe skillet over medium-high heat until very hot. Add the 2 tbsp extra-virgin olive oil and swirl to coat. Carefully place the brined pork loin in the skillet, fat-side down, and sear for 3 to 4 minutes until a deep golden brown crust forms. Flip the pork and sear the other side for another 3 to 4 minutes.
Remove the pork from the skillet and reduce heat to medium. Working quickly, press the celery crown mixture firmly onto all sides of the pork, creating an even coating. Return the skillet to the heat for 1 to 2 minutes to crisp the celery crown slightly before transferring to a preheated 425°F oven.
Roast to Perfect Doneness
Roast the pork loin for 20 to 25 minutes, or until the internal temperature reaches 145°F when measured with a meat thermometer in the thickest part. The celery crown should be golden brown and crispy. Remove the pork from the oven and let it rest for 15 minutes before carving.
During this resting period, the juices redistribute throughout the meat, ensuring each slice remains moist and flavorful. The celery crown will maintain its crunch while the pork reaches its ideal texture. For best results, slice the pork against the grain into 1-inch thick medallions.
Prepare the Smoky Herb Gravy
In the same skillet used for searing, add the 4 minced garlic cloves and cook for 30 seconds until fragrant. Deglaze the pan with the 0.5 cup dry white wine, scraping up any browned bits from the bottom. Add the 2 cups beef stock and bring to a simmer.
In a small bowl, whisk together the 2 tbsp all-purpose flour and 0.25 cup chopped fresh thyme leaves with 1 tbsp chopped fresh rosemary. Gradually whisk this mixture into the simmering stock until smooth. Continue cooking until the gravy thickens enough to coat the back of a spoon, about 5 to 7 minutes. Strain through a fine-mesh sieve before serving.
Pro Tips For Making America'S Test Kitchen Pork Loin
- USE A THERMOMETER: The ATK recipe calls for 145°F internal temp, but I’ve seen pork loin walk away from the pan at 135°F if you’re not paying attention. Invest in a cheap instant-read thermometer—it’s the only way to guarantee juicy, not dry, meat, especially with a lean cut like center-cut pork loin.
- BRINE THE LOIN OVERNIGHT: This isn’t optional. The ATK recipe’s sugar-salt brine is designed to tenderize and season deeply, but rushing it means the crust will be weak and the inside will taste bland. Even if you’re short on time, at least brine for 4 hours—just don’t skip it entirely.
- DON’T SKIP THE CELERY STALK: Yes, it’s just one stalk, but it’s not just for flavor—it’s for texture. The ATK recipe uses it to mimic the fibrous bite of a proper roast, and omitting it makes the dish feel flat. If you hate chopping celery, buy pre-cut celery salt and use half the amount, but don’t leave it out entirely.
- SEAR IN BATCHES: High heat is key for that caramelized crust, but I’ve ruined more pork loins than I’d admit by overcrowding the pan. Sear the first side completely, then move it aside and work in batches. The second sear is where the magic happens—don’t rush it, even if it means your kitchen smells like heaven for 10 extra minutes.
Essential equipment for great america's test kitchen pork loin
Must-Have Pan
Start with a 12-inch cast iron skillet—my go-to is a Lodge Pre-Seasoned—because it handles high heat like a champ while creating that perfect crust. The deep sides help contain the celery crown mixture during searing, and it transitions seamlessly from stovetop to oven.
For a budget-friendly alternative, a stainless steel skillet from All-Clad works just as well, though it requires more attention to even heat distribution. 🔥
Precision Thermometer
Never guess temperatures again—use a ThermoWorks Smoke or Meater Plus to monitor both the pork's internal temp and your oven's accuracy. I check the thickest part of the loin at 145°F for perfect doneness, and the probe's instant feedback prevents overcooking.
For grilling, these thermometers also alert you when your heat source reaches the ideal 425°F sear temperature. A basic instant-read thermometer works, but these models track trends over time.
Breading Tools
For the celery crown, I use a microplane to slice the celery into fine matchsticks—this creates maximum surface area for crisping. A pizza cutter works in a pinch, but the microplane gives you more control.
Keep a small offset spatula handy to press the breading firmly onto the pork without smashing it. I also recommend a fine-mesh sieve for straining the gravy to remove any herb stems or flour lumps.
Oven Thermometer
Your oven's temperature display is often inaccurate—verify with an Oven Thermometer like the Thermoworks Oven Thermometer. I've seen ovens run 25°F hotter or colder than set, which directly affects your pork's texture.
Calibrate yours by adjusting the oven's knob until it matches the probe's reading at 425°F. This small step ensures your celery crown crisps perfectly every time. 🌡️
Resting Rack
After roasting, transfer the pork to a wire rack set inside a rimmed baking sheet. This elevates the meat, allowing air to circulate and preventing soggy bottoms. I use a Viking brand rack for its sturdy construction, but any kitchen-grade rack works.
The 15-minute rest is crucial—it lets juices redistribute, so every slice stays juicy. Pro tip: Place a thermometer probe in the thickest part during resting to confirm it holds at 145°F.
Optional: Smoker Box
For that extra smoky depth in the gravy, add a small charcoal smoker box filled with hickory or applewood chips to your skillet during the final 5 minutes of gravy reduction. The indirect smoke infuses the wine and stock with subtle woodiness.
I use Traeger brand chips for consistent flavor, but any food-grade wood works. Just monitor closely—smoke can intensify quickly in a small pan. 💫

Frequently asked questions
Why does America's Test Kitchen recommend brining pork loin?
Brining pork loin for 12-24 hours creates a moisture barrier that locks in juices during cooking. The salt and sugar solution penetrates the meat, ensuring a tender, flavorful result with perfect texture. This method prevents dryness, especially important for lean cuts like pork loin. The cold brine also helps maintain an even temperature throughout the process.
Can I substitute the celery crown with another topping?
For a herb crust, mix 1 tbsp chopped rosemary and 1 tbsp chopped thyme with 0.5 cup panko and 2 tbsp melted butter. For a garlic-parsley version, replace celery with 0.5 cup chopped parsley and 3 minced garlic cloves. Both alternatives work beautifully with the same technique.
How do I adjust cooking time if my pork loin is thicker or thinner?
For every 0.25-inch thicker than 1.5-inch, add 5 minutes to roasting time. For thinner cuts (1-inch or less), reduce by 5 minutes. Always use a meat thermometer—145°F internal temperature is your target. The celery crown adds 1-2 minutes extra cooking time, so account for that in your adjustments.
What's the best way to reheat leftover pork loin?
Slice the pork into 1-inch medallions and reheat in a 350°F oven for 10-15 minutes until reaching 145°F internally. For the celery crown, reheat separately at 375°F for 3-4 minutes to restore crispiness. Avoid microwaving—it makes the meat rubbery. The gravy reheats well on the stovetop over medium-low heat.
Can I make this recipe on the grill instead of the oven?
Yes! Sear the brined pork loin on the grill over medium-high heat for 4-5 minutes per side until browned. Apply the celery crown mixture, then move to indirect heat (coals on one side) and cook until 145°F internal temperature, about 20-25 minutes. For the gravy, use the same skillet method on the grill's side burner. The smoky flavor pairs perfectly with the celery crown!
