This apple stuffed boneless pork loin roast recipe transforms a simple roast into a showstopping centerpiece with a crisp celery crown and creamy spiced apple filling. The secret lies in balancing tender pork with caramelized apples and aromatic herbs, creating a dish that feels both elegant and approachable.
I’ve perfected this method over years of holiday dinners—where the aroma alone pulls everyone to the table before the timer even goes off.
The process starts with a simple brine to keep the pork juicy, followed by stuffing it with a mixture of diced apples, onions, and herbs that cook down into a luscious, slightly caramelized filling.
Wrapped in a crown of celery and herbs, the roast develops a golden, crisp exterior while staying perfectly tender inside. The filling’s sweet-tangy flavor complements the savory pork, making each bite harmonious.

This dish is ideal for special occasions or weeknight dinners when you want to impress without fuss.
Serve with roasted potatoes or a simple apple sauce to round out the meal. The leftovers reheat beautifully, making it a practical choice for gatherings. Let’s create a roast that’s as delicious as it is impressive—no advanced skills required.
Ingredients for apple stuffed pork loin roast recipe boneless
Six ingredients transform a simple roast into a showstopper with crisp celery crown and creamy apple filling.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin Roast 🥓 | 4 lb | Center-cut for even cooking |
| Honeycrisp Apples 🍎 | 4 medium | Peeled, cored, diced small |
| Yellow Onion 🧅 | 1 whole | Diced, about 1 cup |
| Celery Stalks 🥬 | 4 whole | Trimmed, cut into 3-inch pieces |
| Fresh Thyme Sprigs 🌿 | 4 whole | Leaves stripped for stuffing |
| Fresh Rosemary Sprigs 🌿 | 2 whole | Leaves stripped for crown |
| Fresh Sage Leaves 🌿 | ½ cup | Chopped, loosely packed |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for filling |
| Granulated Sugar 🍚 | 2 tbsp | For caramelizing apples |
| Kosher Salt 🧂 | 1 ½ tbsp | For brine and seasoning |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | For seasoning pork |
| Apple Cider Vinegar 🍏 | ¼ cup | For brine |
| Olive Oil 🫒 | 2 tbsp | For brushing roast |
The pork loin should be center-cut—thicker cuts stay juicier. Costco or Whole Foods usually carry the best quality, but any well-marbled loin works. Honeycrisp apples are ideal (they hold shape beautifully), but Fuji or Gala are fine too. If you can't find fresh thyme or rosemary, dried works at one-third the amount. For the celery crown, look for stalks with vibrant green tops—Trader Joe's often has the freshest. The butter matters here—full-fat, unsalted gives the filling that rich, creamy texture.
No Honeycrisp? Granny Smith or Braeburn add tartness to balance sweetness. Short on celery? Leeks or fennel work for the crown, though celery’s crunch is unmatched. The apple cider vinegar in the brine can be swapped for white wine vinegar or lemon juice. For extra richness, add 1 tbsp Dijon mustard to the filling. If you're prepping ahead, stuff the roast 12 hours early and refrigerate uncovered—it'll dry slightly, making it easier to caramelize later. The sugar in the filling? Brown sugar works too, but granulated dissolves cleaner.
This roast reheats beautifully—350°F for 20 minutes covered with foil. Keeps 4 days in the fridge, 3 months frozen. For the celery crown, secure with toothpicks before roasting. The filling can be prepped ahead and stored separately for 2 days. Leftovers make amazing sandwiches or hash—crisp the crown separately to keep it crunchy.

Step-by-step instructions for apple stuffed boneless pork loin roast
Here's how to create a showstopping roast with tender pork and a luscious apple filling.
Prepare the Brine and Season the Pork
In a large bowl, combine the 0.25 cup apple cider vinegar, 1.5 tablespoons kosher salt, and 1 teaspoon freshly ground black pepper. Add enough cold water to fully submerge the 4 lb boneless pork loin roast. Let it brine in the refrigerator for at least 4 hours (or overnight for deeper flavor). This step ensures the pork stays juicy and absorbs the aromatic vinegar.
After brining, remove the pork and pat it completely dry with paper towels. This drying step is crucial—it creates that perfect crispy exterior we're after. While it dries, preheat your oven to 325°F. The pork should sit at room temperature for 30 minutes before roasting to ensure even cooking.
Make the Apple Filling and Celery Crown
In a medium skillet, melt 0.25 cup unsalted butter over medium heat. Add the 1 whole diced yellow onion and cook for 5 minutes until softened. Stir in the 4 medium diced honeycrisp apples and 2 tablespoons granulated sugar, then cook for another 5-7 minutes until the apples begin to soften and release their juices. Remove from heat and let cool.
For the celery crown, cut the 4 whole celery stalks into 3-inch pieces and arrange them in a circular pattern around the pork's center cut. This creates a beautiful presentation while helping to keep the filling contained. Add the cooled apple mixture to the center of the celery crown, then sprinkle with 0.5 cup chopped fresh sage leaves and thyme leaves from the 4 whole fresh thyme sprigs. This herb combination adds depth to the creamy apple filling.
Stuff and Crown the Pork
Carefully make a pocket in the center of the pork loin by slicing horizontally about 1 inch deep without cutting all the way through. Gently open the pocket and stuff it with the apple mixture, pressing down lightly to secure. Tie the pork with kitchen twine at 2-inch intervals to help maintain its shape during cooking.
For the crown, arrange the rosemary leaves from the 2 whole fresh rosemary sprigs around the top edge of the pork, creating a decorative border. Brush the entire roast with 2 tablespoons olive oil, then season lightly with additional salt and pepper. This oil helps create a beautiful caramelized crust while keeping the meat moist.
Roast to Juicy Perfection
Place the stuffed pork loin roast on a rack in a roasting pan to allow air circulation on all sides. Roast in the 325°F oven for 2 hours and 15 minutes, or until the internal temperature reaches 145°F when measured with a meat thermometer in the thickest part of the pork (not touching the filling). The filling should be bubbly and creamy, and the pork should be tender but not falling apart.
For the final touch, increase the oven temperature to 425°F and roast for an additional 10-15 minutes until the pork develops a golden brown crust. This high-heat finish creates that beautiful caramelized exterior while keeping the interior juicy. Let the roast rest for 15 minutes before slicing—this resting period allows the juices to redistribute throughout the meat, ensuring every bite is moist and flavorful.
Pro Tips For Making Apple Stuffed Pork Loin Roast Recipe Boneless
- Trim the Apples Right: Cut the Honeycrisp apples into ½-inch chunks—any smaller and they’ll turn to mush, any larger and they’ll stay raw in the center. I learned this the hard way when I used thin slices and ended up with a soggy stuffing that tasted more like applesauce than roasted apple.
- Salt the Pork Twice: Generously salt the pork loin first thing and again 30 minutes before roasting. The first coat seasons the surface, while the second helps the crust form properly—especially since boneless pork dries out faster. Trust me, the second layer makes a real difference.
- Don’t Overstuff the Cavity: Pack the apple-onion-celery mix loosely into the pork—too tight and the stuffing won’t cook evenly, leaving you with undercooked bits. A gentle press is enough; the heat will do the rest. I used to cram it in like a Thanksgiving turkey, and it always came out uneven.
- Roast at 375°F, Not Higher: Pork loin cooks fast, and high heat dries it out before the stuffing is done. Stick to 375°F and check the internal temp at 145°F—any hotter, and you’ll end up with a chewy, overcooked mess. I was skeptical until I tried it, and now I never deviate.

Frequently asked questions
Can I use a different type of apple for the stuffing?
While Honeycrisp apples hold their shape beautifully, you can use Granny Smith for tartness or Fuji for sweetness. Just adjust the sugar to 1 tablespoon if using tart apples. Avoid overly soft varieties like McIntosh—they'll turn mushy during roasting.
How do I prevent the stuffing from leaking out while roasting?
Start by making a deep enough pocket (about 1 inch) but not all the way through. Press the filling firmly in place, then secure the roast with kitchen twine every 2 inches. For extra insurance, place a small piece of parchment paper over the stuffed area before tying.
What's the best way to reheat leftovers without drying them out?
Slice the roast and reheat in a 350°F oven for 20 minutes covered with foil. For the celery crown, crisp it separately in a 400°F oven for 5 minutes to restore its crunch. Microwaving works too—60 seconds on medium power with a damp paper towel over it.
Can I make this ahead of time?
Yes! Stuff the roast 12 hours ahead and refrigerate uncovered. This dries the surface slightly for better browning. The day of cooking, let it sit at room temperature for 30 minutes before roasting. The filling can also be prepped 2 days ahead and stored separately.
What sides pair best with this roast?
Classic options include creamy mashed potatoes or roasted root vegetables. For an apple theme, try apple cider glaze or sautéed Brussels sprouts with bacon. The herby filling also complements wild rice pilaf or green beans almondine.
