Boneless Pork Roast Grill Recipe: Smoky Shreds With Crispy Celery Crown Topping

This boneless pork roast grill recipe transforms simple ingredients into melt-in-your-mouth, smoky shreds with a crispy celery crown topping—no fancy cuts required. 🔥 As a pitmaster who grew up on slow-cooked ribs, I’ve perfected the balance between tender meat and bold flavor using just a grill and a few key techniques.

The secret lies in high-heat searing followed by low-and-slow cooking, ensuring juicy results every time.

What sets this recipe apart is the celery crown—thinly sliced celery wrapped around the roast and charred to crispy perfection. It adds a smoky, slightly sweet contrast that elevates the dish from ordinary to extraordinary.

The marinade, a blend of bold spices and citrus, penetrates deeply, while the reverse sear method guarantees a perfect crust without drying out the meat. This isn’t just another grill recipe; it’s a showstopper that delivers restaurant-quality flavor at home.

The magic happens when you combine crispy edges with tender, shreddable pork that falls apart at the touch of a fork. The celery crown, charred to golden perfection, becomes a textural highlight, adding crunch and depth to each bite.

Whether you’re feeding a crowd or treating yourself to a special meal, this recipe delivers results that taste like they’ve been simmering for hours—even though it’s all done on the grill.

Pair it with grilled vegetables or a fresh salad to round out the meal, or serve it as-is for a hearty, satisfying main course. The best part? This method works with any boneless pork roast, making it versatile enough for weeknight dinners or weekend gatherings.

Let’s get cooking—your grill is about to become the star of the show.

Ingredients for boneless pork roast grill

Six ingredients transform simple pork into restaurant-worthy grill masterpiece with crispy, smoky perfection.

The pork roast is your canvas—center-cut delivers even cooking, while boneless ensures easy handling on the grill. Costco or local butchers often carry pre-cut roasts, but if buying whole, trim excess fat for cleaner flavor. Celery and onion for the crown should be fresh and crisp, not woody or limp. Look for stalks with vibrant green tops and firm texture. The marinade ingredients are all pantry staples, but smoked paprika from Penzeys or bulk bins elevates the smoky depth—don't skimp here. For the celery crown, slice stalks lengthwise into thin strips (about 1/8-inch thick) for even charring.

No smoked paprika? Substitute 1 tbsp regular paprika plus 1 tsp liquid smoke, though the flavor won't be identical. Short on fresh thyme? Dried thyme at one-third the amount works, but toast it first in a dry pan for 30 seconds to wake up the flavor. The orange zest can be swapped for lemon, but orange pairs beautifully with pork. For the celery crown, if you're short on celery, add thinly sliced bell pepper for color and crunch. The honey in the glaze is non-negotiable—it caramelizes beautifully on the grill and adds that touch of sweetness that balances the smokiness. If you're avoiding honey, maple syrup works as a 1:1 substitute.

Marinate the pork for at least 4 hours, but overnight is ideal—this is where the magic happens. Store leftover marinade in an airtight container in the fridge for up to 5 days, though I rarely have any left. The celery crown can be prepped ahead and stored wrapped in plastic for 2 days—just don't let it sit too long before grilling. Cooked pork keeps 3-4 days refrigerated, but it reheats beautifully. For leftovers, shred and store in the fridge for sandwiches or tacos—double the marinade if you're making extra pork for these purposes. The celery crown loses its crispiness when reheated, so it's best served fresh off the grill.

Step-by-step instructions for smoky shredded pork roast

Here's how to transform a simple boneless pork roast into tender, smoky shreds with a crispy celery crown topping.

Start by trimming any excess fat from the 4 lb boneless pork roast and patting it completely dry with paper towels. This step is crucial for achieving that crispy exterior we're after. While the pork rests at room temperature for 30 minutes, prepare the celery crown topping by thinly slicing the 8 whole celery stalks and 1 whole yellow onion into ¼-inch thick rounds. Keep these in a bowl and set aside.

In a small bowl, combine the 0.25 cup fresh thyme leaves, 1 tbsp orange zest, 1 tbsp honey, and 1 tbsp Dijon mustard. Mix well and set aside for later. The citrus and sweetness in this blend will enhance the smoky flavors of the pork and add a bright contrast to the rich meat.

In a large mixing bowl, whisk together the 0.5 cup olive oil, 0.25 cup apple cider vinegar, 0.25 cup packed brown sugar, 2 tbsp smoked paprika, 1 tbsp ground black pepper, and 1 tbsp salt. Add the 8 minced garlic cloves and the thyme-honey-mustard mixture. Stir well to combine all ingredients into a smooth marinade.

Place the pork roast in a large resealable plastic bag and pour the marinade over it. Gently massage the marinade into the pork, ensuring it's evenly coated on all sides. Seal the bag and refrigerate for at least 4 hours or overnight. This long marinating time allows the flavors to deeply penetrate the meat, ensuring every bite is packed with smoky, tangy goodness.

Preheat your grill to medium-high heat or 375°F if using a grill pan. Once heated, place the marinated pork roast on the grill, fat-side up if applicable. Grill for 20-25 minutes on each side, or until the internal temperature reaches 195-200°F when measured with a meat thermometer. This temperature ensures the pork will shred easily and remain juicy.

During the last 5 minutes of grilling, spread the celery and onion slices evenly over the top of the pork roast. This creates the crispy crown topping that adds texture and visual appeal. Watch closely as the vegetables begin to caramelize and crisp—you'll see them turn golden brown around the edges.

Once the pork reaches the target internal temperature, transfer it to a cutting board and loosely tent with aluminum foil. Let it rest for 15-20 minutes. This resting period is essential for allowing the juices to redistribute throughout the meat, preventing them from running out when you shred.

After resting, use two forks to shred the pork roast into ¼-inch thick strands. Discard any large fat pieces or connective tissue. The pork should be tender enough to pull apart easily with minimal resistance. If the celery crown topping isn't fully crispy, return it to the grill for an additional 2-3 minutes to achieve that perfect texture.

Transfer the shredded pork to a serving platter and arrange the crispy celery crown topping on top. Drizzle any accumulated juices from the cutting board over the pork for extra flavor. The combination of tender, smoky pork and crispy, caramelized vegetables creates a dish that's both visually stunning and incredibly satisfying.

Serve immediately with your favorite sides, such as roasted sweet potatoes, a fresh green salad, or crusty bread to soak up the delicious juices. This recipe yields 6 generous servings, perfect for a family dinner or gathering with friends.
