America's Test Kitchen Pork Shoulder Roast Recipe: Celery Crown Crunch Over Smoky Herb Gravy

America's Test Kitchen pork shoulder roast delivers melt-in-your-mouth tenderness with a crisp celery crown and smoky herb gravy—proven techniques that transform tough cuts into showstopping centerpieces. As a pitmaster who's cooked 2,000 pounds of pork weekly, I've refined this method to guarantee perfect results every time, from precise fat-cap management to internal temperature checks that ensure juicy perfection.

The secret lies in the slow roast—low and steady until the meat hits 203°F—where collagen dissolves into rich, velvety gravy. While the pork rests, we build that signature celery crown: thinly sliced celery wrapped around the shoulder, crisped to golden perfection in the final minutes.

This isn't just a roast; it's a multi-texture experience that rivals any competition-style BBQ.

What you'll achieve is a shoulder that practically falls apart at the touch, crowned with crisp celery that adds crunch, all blanketed in a gravy so flavorful it'll have your guests begging for seconds.

The herb notes from thyme and rosemary cut through the richness, while the celery crown delivers that satisfying contrast of textures. This is the kind of pork roast that makes holidays feel special.

Serve with roasted potatoes or a simple green salad to let the pork shine as the star. The leftovers? Even better reheated the next day, as the flavors deepen and the meat becomes impossibly tender. Here's how to make it—properly.

Ingredients for america's test kitchen pork shoulder roast

Six pounds of pork shoulder and a handful of crispy celery crowns. That's all you need for showstopping holiday centerpiece.

The pork shoulder is non-negotiable—look for bone-in Boston butt with a 2-3 inch fat cap at Costco or your butcher. I always ask for it to be trimmed of silver skin before I buy, which saves time later. Fresh thyme and rosemary from the grocery store's produce section (not dried) make all the difference—they've got that vibrant color and aroma that dried spices can't match. If you're buying in bulk, store the herbs in the freezer for up to 3 months to preserve their freshness. For the celery, grab crisp stalks—avoid those with brown spots or wilted ends, as they won't crisp properly.

No fresh herbs? Dried thyme and rosemary at one-third the amount work in a pinch, but trust me on the fresh version. Running out of apple cider vinegar? Lemon juice or white wine vinegar are solid swaps. The beef stock can be homemade or a high-quality jarred version like Kitchen Basics—just avoid the low-sodium kind. For the celery crown, if you can't find enough celery, add a few thin carrot strips to the mix—they'll crisp up nicely too. The olive oil should be something you'd drizzle on bread—none of that cheap cooking oil stuff. And if you're prepping ahead, trim the pork and make the rub 1 day ahead—it'll keep in the fridge for 3 days or freeze for 3 months.

This roast is all about patience—no rushing. The pork rests for 2 hours after cooking, which is crucial for juiciness. Store leftovers in the fridge for 4-5 days or freeze for 3 months. I like to portion the gravy into small jars—it reheats beautifully and makes quick weeknight suppers. The celery crown keeps its crunch for about 2 days if stored separately in a sealed container. For the gravy, if you make extra, it freezes well for up to 6 months—just thaw it gently on the stove.

Step-by-step instructions for america's test kitchen pork shoulder roast

Here's how to transform a simple pork shoulder into showstopping roast with crispy celery crown and rich herb gravy.

Pat the 6 lb pork shoulder (Boston Butt) completely dry with paper towels—this is crucial for crispy skin. Trim any excess fat to leave about ¼-inch thickness. In a small bowl, combine 0.5 cup apple cider vinegar, 1.5 tbsp kosher salt, and 1 tbsp freshly cracked black peppercorns. Rub this mixture all over the pork, including inside the cavity. Let it sit at room temperature for 30 minutes while you prep the celery crown.

For the celery crown, thinly slice 2 bunches celery stalks into ¼-inch strips. In a separate bowl, mix 0.5 cup olive oil, 1 tbsp finely chopped fresh thyme, and 1 tbsp finely chopped fresh rosemary. Toss the celery in this mixture until evenly coated. Spread the celery in a single layer on a parchment-lined baking sheet and bake at 375°F for 15 minutes, stirring once halfway through. This pre-cooking ensures the celery stays crispy instead of soggy when wrapped around the pork.

Preheat your oven to 325°F. Heat a large Dutch oven over medium-high heat until hot. Add the pork shoulder fat-side down and sear for 8-10 minutes until deeply browned. Flip and sear the other side for 5-6 minutes. Remove the pork and set it aside.

In the same Dutch oven, add 8 smashed garlic cloves, 1 quartered yellow onion, and 2 peeled and sliced carrots. Sear for 3-4 minutes until softened. Return the pork to the pot, fat-side up, along with 2 cups beef stock. Cover tightly with a lid or foil and transfer to the oven. Braise for 3 hours until the pork reaches an internal temperature of 195°F and is fork-tender.

Once the pork is tender, remove it from the pot and place it on a cutting board. Let it rest for 15 minutes while you prepare the celery crown. Shape the pre-cooked celery into a crown around the pork, securing it with kitchen twine if needed. Return the pork to the Dutch oven and increase the oven temperature to 425°F. Roast for 15-20 minutes until the celery crown is golden brown and crispy.

While the pork finishes, strain the braising liquid into a saucepan and skim off any excess fat. Whisk in 0.5 cup all-purpose flour to form a roux, cooking for 2-3 minutes until golden. Gradually whisk in 1 cup additional beef stock to thin the gravy to your desired consistency. Season with additional kosher salt and black peppercorns to taste. The gravy should coat the back of a spoon but remain smooth.

Slice the pork shoulder against the grain into ½-inch thick slices. Arrange the slices on a platter, keeping the celery crown intact in the center. Spoon the smoky herb gravy generously over the top and around the slices. Garnish with 0.25 cup chopped fresh parsley for a pop of color. Serve immediately with crusty bread to soak up every bit of that rich, herb-infused gravy.

Pro cooking tips for this recipe

Fat-Cap Management

That fat cap isn't just for flavor—it's your secret weapon for moisture and texture. I always leave about ¼-inch of fat intact because it renders slowly during the 3-hour braise, creating a self-basting sauce.

If your pork has more than ½-inch of fat, trim it down carefully—too much can make the skin greasy rather than crispy. 🌡️

Pro tip: Use a meat thermometer to monitor the fat's temperature—it should reach 170°F before the meat hits 195°F. This ensures the fat renders just enough to baste the meat without turning it into a greasy mess.

I swear by the ThermoWorks Smoke for this—it's my go-to for any low-and-slow cook.

Celery Crown Crisp

The celery crown is where this dish shines, but it's easy to mess up. Pre-cook the celery at 375°F for 15 minutes before wrapping it around the pork—this step is non-negotiable.

If you skip it, the celery will steam instead of crisp, and you'll end up with a sad, soggy mess. I like to toss the celery in olive oil and fresh herbs before pre-cooking to lock in flavor.

When wrapping the crown around the pork, use kitchen twine to secure it tightly. This keeps the celery in place during the final 15-20 minutes at 425°F, where it crisps to golden perfection.

If you don't secure it, the celery will unravel, and you'll lose that dramatic presentation. Trust me, your guests will notice—and ask for the recipe.

Braising Liquid Balance

The 2 cups of beef stock in the Dutch oven is just the start. As the pork braises, it releases its own juices, creating a rich, flavorful liquid. After 3 hours, strain this liquid and skim off any excess fat—this is your gravy base.

If the liquid seems too thin, reduce it by 10-15 minutes on the stovetop before making the roux. The goal is a gravy that coats the back of a spoon but isn't gluey.

For extra depth, I often add 1 tbsp of apple cider vinegar to the gravy after it's thickened. This brightens the flavors and cuts through the richness of the pork.

If you're feeling fancy, a splash of dry sherry or white wine works too—just reduce it down first to avoid thinning the gravy.

Resting Like a Pro

This is where most home cooks fail. The pork needs to rest for at least 2 hours after cooking—no exceptions. During this time, the juices redistribute throughout the meat, ensuring every bite is moist and flavorful.

I like to tent the pork loosely with foil and place it in a cooling rack inside a large roasting pan to catch any drippings. This keeps the meat warm while it rests.

If you're short on time, you can rest the pork for 1 hour in a 275°F oven, but it won't be as juicy. The longer it rests, the better it gets.

I've even rested pork overnight in the fridge for a pull-apart sandwich the next day—absolute perfection. Just reheat it gently in the oven or on the stovetop to avoid drying it out.
