Ingredients for america's test kitchen pork loin
Precision-crafted ingredients for a restaurant-worthy pork loin with crisp celery crown and herb-infused gravy.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin (Center Cut) 🐖 | 1 ½ lb | Bone-in, 1.5-inch thick |
| Kosher Salt 🧂 | 1 ½ tbsp | For brining and seasoning |
| Granulated Sugar 🍚 | 1 tbsp | For brine balance |
| Cold Water 💧 | 4 cups | For brine preparation |
| Unsalted Butter 🧈 | ½ cup | Cold, for searing |
| Celery Sticks 🧅 | 1 ½ cups | Thinly sliced, 1/4-inch thick |
| Japanese Panko Breadcrumbs 🍞 | 1 cup | For celery crown |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Chopped, for gravy |
| Fresh Rosemary 🌿 | 1 tbsp | Chopped, for gravy |
| All-Purpose Flour 🌾 | 2 tbsp | For gravy thickening |
| Chicken Stock 🥣 | 1 cup | Low-sodium preferred |
| Heavy Cream 🥛 | ¼ cup | For gravy richness |
| Garlic Cloves 🧄 | 2 cloves | Minced, for gravy |
| Fresh Parsley 🌿 | 2 tbsp | Chopped, for garnish |
The pork loin is the foundation—center-cut ensures even cooking and maximum tenderness. Look for bone-in cuts at Whole Foods or your local butcher, as the bone helps stabilize the meat during roasting. A 1.5-inch thickness is ideal for perfect doneness at 325°F. For the celery crown, Trader Joe's sells pre-cut celery sticks, but slicing your own ensures uniformity. The Japanese panko is non-negotiable—its light, airy texture creates the perfect crunch without weighing down the crown. If you can't find it, toast regular breadcrumbs in a dry pan for 3-4 minutes to mimic the texture.
No kosher salt? Diamond Crystal kosher salt is the gold standard, but Morton coarse salt works in a pinch—just measure carefully. The chicken stock should be low-sodium to avoid overpowering the delicate herb flavors; Pacific Foods or Kitchen Basics brands are excellent choices. For the gravy, fresh herbs make all the difference—thyme and rosemary should be vibrant and fragrant, not wilted. If you're short on time, dried herbs work at one-third the amount, but the flavor won't be as bright. The heavy cream adds richness; if you prefer a lighter gravy, substitute with half-and-half or whole milk for a subtler touch.
Prep the celery crown components ahead and store them in separate airtight containers in the fridge for up to 2 days—this keeps the celery crisp and the panko dry. The cooked pork loin reheats beautifully; wrap it tightly in foil and warm in a 325°F oven for 15 minutes. The gravy can be made a day ahead and reheated gently on the stove—just whisk in a splash of cold water or stock to restore its smoothness. For meal prep, portion the gravy into small jars and store it in the fridge for up to 5 days or freeze for 3 months. The celery crown loses its crunch when reheated, so it's best served fresh alongside the warm pork.
Why You'll Love This Recipe
- Five-Ingredient Magic: I swear, this recipe uses five things—just salt, sugar, water, butter, and pork. That’s it. No fancy marinades, no herb bundles, no stress. The secret? The sugar-butter glaze caramelizes into something so rich, you’ll think you slaved over it for hours.
- Crispy-Creamy Payoff: Between us, that sugar-salt crust on the outside? Chef’s kiss. It cracks open like a perfect sear while the inside stays juicy enough to make you sigh. The butter bastes it into something dangerously addictive—like a cross between a roast and a dessert.
- Weeknight Hero: This is my go-to when I’m too tired to think. Toss the pork in the oven, stir a pan of sugar and water, and let it do its thing. By the time I’m chopping veggies for the side, this is already resting—no hovering, no last-minute panic.
- Leftovers That Don’t Suck: Cold pork loin? Actually better the next day. I slice it thin for sandwiches, cube it into salads, or just eat it straight with mustard—no one complains. And because it’s budget-friendly (center-cut pork is a steal), I feel zero guilt about making extra.
Step-by-step instructions for america's Test Kitchen pork loin recipe
Master this refined technique for perfectly tender pork with a crisp celery crown and velvety herb gravy.
Prepare the Brine for Maximum Tenderness
In a large bowl, combine the 4 cups cold water, 1.5 tablespoons kosher salt, and 1 tablespoon granulated sugar until fully dissolved. The sugar helps balance the salt while preventing the pork from becoming overly salty. Submerge the 1.5 lb pork loin completely in the brine, ensuring it's fully covered. Cover and refrigerate for at least 4 hours or up to overnight. This step guarantees moisture retention and even seasoning throughout the thick cut.
Real talk: Brining is non-negotiable for pork loin. Without it, you risk dryness in the center. I've found that letting the pork sit uncovered for 10 minutes after removing from the brine helps prevent a soggy crust later. Pat the pork dry thoroughly with paper towels before proceeding—this ensures a proper sear rather than a steamed exterior.
Create the Celery Crown and Sear the Pork
In a separate bowl, toss the 1.5 cups celery sticks with 1 cup Japanese panko breadcrumbs until evenly coated. Heat a large oven-safe skillet over medium-high heat and add the 0.5 cup unsalted butter. Once the butter foams, add the celery crown mixture in an even layer, pressing down gently. Cook for 3-4 minutes until the celery is tender and the panko turns golden brown.
Remove the celery crown and set aside. In the same skillet, increase heat to high and sear the pork loin for 2-3 minutes per side until it develops a deep golden-brown crust. The reason we sear first is to lock in those juices—don't skip this step. Transfer the skillet to a 425°F preheated oven and continue roasting for 15-20 minutes or until the internal temperature reaches 145°F when measured at the thickest part.
Build the Herb-Infused Gravy
While the pork rests, reduce the oven temperature to 350°F and return the celery crown to the skillet. Add the 2 cloves minced garlic and cook for 1 minute until fragrant. Sprinkle the 2 tablespoons all-purpose flour over the celery and stir constantly for 1 minute to remove any raw flour taste. Slowly pour in the 1 cup chicken stock, scraping up any browned bits from the bottom of the skillet.
Simmer for 3-4 minutes until the mixture thickens slightly. Remove from heat and stir in the 0.25 cup heavy cream, 1 tablespoon chopped fresh thyme leaves, and 1 tablespoon chopped fresh rosemary. Season with additional salt and pepper if needed. The gravy should coat the back of a spoon but remain silky smooth—not gluey.
Rest and Serve with Perfect Technique
Transfer the pork loin to a cutting board and tent loosely with foil. Let it rest for 10-15 minutes—this critical step allows the juices to redistribute, ensuring each slice remains moist. Meanwhile, keep the celery crown and gravy warm in the skillet over low heat. The pork is done when it reaches 145°F internally and the juices run clear when pierced with a meat thermometer.
Slice the pork loin into ½-inch thick medallions against the grain for maximum tenderness. Arrange the slices on a warm platter, spoon the herb-infused gravy over the top, and garnish with 2 tablespoons chopped fresh parsley. Serve immediately with the crisp celery crown on the side—this contrast of textures and temperatures makes the dish unforgettable.
Pro Tips For Making America'S Test Kitchen Pork Loin
- USE A THERMOMETER: The recipe’s internal temp matters more than time—aim for 145°F when the pork hits that spot, it’ll pull away from the bone like butter. I used to guess and ended up with either dry slices or sad, pink centers.
- DRY THE LOIN WELL: Pat that pork thoroughly with paper towels before searing—wet meat steams instead of browns. I learned this the hard way when my first batch came out soggy underneath the crust.
- DON’T RUSH THE BRINE: Let the saltwater solution sit for at least 30 minutes (up to 2 hours if you’re patient). Rushing means the pork absorbs less flavor and stays bland—yes, even if you’re starving.
- BUTTER IN LAYERS: Spread half the butter before roasting, then add the rest after searing. This gives you crispy edges and a rich, melted finish—no need to fight for both textures.
Storing and reheating this america's test kitchen pork loin
Refrigerator Storage
Store your cooked pork loin in an airtight container with the celery crown and gravy separated. The pork stays fresh for 3-4 days when refrigerated at 40°F or below. I like using glass Pyrex containers because they don't absorb odors and reheat beautifully.
The celery crown loses its crispness when stored, so serve it fresh or prepare it fresh each time. 🥗
Freezer Storage
For longer storage, wrap the pork loin tightly in plastic wrap, then place it in a freezer bag with all excess air removed. The pork freezes well for up to 3 months while maintaining texture and flavor.
The gravy can be frozen separately in a small jar—just thaw it in the fridge overnight before reheating. Never refreeze gravy once thawed, as it can become grainy.
Reheating Pork Loin
For the best results, reheat pork loin in a 325°F oven for 15-20 minutes wrapped in foil. This method preserves moisture and prevents drying out. If you're short on time, use the microwave on 50% power for 2-3 minutes, then let it rest for 5 minutes before serving.
The internal temperature should reach 165°F when reheating.
Reviving Celery Crown
The celery crown doesn't reheat well, but you can crisp it up again by tossing it in a hot skillet with 1 tablespoon butter for 1-2 minutes until golden.
This works best if you store the celery crown components separately—just recombine them before reheating. For extra crunch, sprinkle with 1 teaspoon panko and toast in the skillet. 🔥
Gravy Restoration
If your gravy thickens too much when reheated, thin it with 1-2 tablespoons cold water or chicken stock. For extra richness, stir in 1 tablespoon heavy cream or butter. Avoid boiling the gravy, as this can cause it to separate.
Instead, heat it gently on low-medium heat while stirring constantly. A splash of lemon juice brightens flavors if the gravy tastes flat after reheating.
Meal Prep Tips
Prep components ahead for easy assembly: store the cooked pork loin, gravy ingredients (flour, stock, herbs), and celery crown separately. On serving day, reheat the pork and make the gravy fresh. This approach keeps the celery crown crispy and the gravy velvety.
For a quick weeknight meal, I often prep the gravy ingredients in advance and assemble them in 5 minutes while the pork reheats. ✨

Frequently asked questions
Why does America's Test Kitchen recommend brining the pork loin?
Brining ensures maximum tenderness by preventing moisture loss during cooking. The 4-hour minimum soak in saltwater solution keeps the meat juicy while allowing even seasoning throughout the thick cut. Without brining, pork loin can dry out—especially when roasted at 325°F for even cooking.
Can I substitute regular breadcrumbs for Japanese panko in the celery crown?
You can try, but panko's light, airy texture creates the perfect crunch. Toast regular breadcrumbs in a dry pan for 3-4 minutes to mimic panko's crispiness. For best results, stick with panko—it's worth the small investment for that signature crunch.
What's the secret to getting perfectly crisp celery crown?
Cook the celery crown in hot butter over medium-high heat for exactly 3-4 minutes until golden brown. Press down gently with a spatula to ensure even browning. Remove immediately after cooking to prevent sogginess while the pork rests.
How do I know when the pork loin is fully cooked?
Use a meat thermometer to check the thickest part—it should reach 145°F. The juices should run clear, not pink. Let it rest for 10-15 minutes before slicing to redistribute juices and maintain tenderness. Never cut into it too soon!
Can I make the gravy ahead of time?
Yes! Prepare the gravy ingredients (flour, stock, herbs) separately and store in the fridge for up to 3 days. When ready to serve, combine and simmer until thickened. For extra richness, whisk in 1 tablespoon cold butter at the end.
