9-Pound Pork Loin Recipe: Medium-Rare Core Guaranteed With Crispy Celery Crown

A 9-pound pork loin cooked to medium-rare perfection with a crispy celery crown is the centerpiece every holiday table deserves. This recipe delivers a juicy, tender core with a golden, crackling crust that holds up to a crowd—no guesswork, just guaranteed results.

I've perfected this method after years of roasting whole pigs in my Atlanta kitchen, where precision matters most.

The secret lies in dry-brining overnight to ensure moisture retention and a flawless crust, followed by precise basting with rendered fat to keep the surface sizzling while the center stays pink.

A celery crown—tied with twine and roasted alongside—adds dramatic flair and crispy texture that pairs beautifully with the rich pork. This isn't just a recipe; it's a technique that transforms a simple roast into a showstopper.

By the time you carve into this perfectly pink center, your guests will never know it took just 3 hours (plus prep). The pork rests while you assemble sides—think honey-glazed carrots or herb butter potatoes—so everything arrives hot and ready.

Every slice delivers that melt-in-your-mouth tenderness with a crisp exterior that's impossible to resist.

Serve with apple-cider gravy or a balsamic reduction to elevate the flavors further. This is the kind of pork loin that makes people ask for seconds—and thirds. Let's get cooking.

Ingredients for 9 pound pork loin

A 9-pound pork loin deserves quality ingredients to shine—this list delivers crispy perfection.

The pork loin is non-negotiable here—bone-in, center-cut is essential for even cooking and that melt-in-your-mouth tenderness. Local butchers or high-end grocers like Whole Foods carry the best cuts, but don't stress if you find a good deal at Costco—just ensure it's well-marbled. For the celery crown, farmers markets often have the freshest, stringiest stalks—look for ones with vibrant green tops. The herbs? Fresh is a must—dried just won't cut it for this showstopper. I always buy extra rosemary because it keeps for months in the freezer once chopped.

No fresh rosemary? Dried at half the amount works in a pinch, but trust me, it's worth tracking down. Running low on celery? Substitute fennel stalks—they have a similar anise flavor and crisp up beautifully. The butter for basting should be cold and cubed—don't melt it ahead of time, or you'll lose that golden crust. For the basting liquid, apple cider vinegar plus honey creates that perfect balance of tangy and sweet. Need a shortcut? Store-bought pork rub can replace the salt and pepper, but I prefer the fresh herbs for that restaurant-quality flavor.

Store the pork uncovered in the fridge for 24 hours before cooking—this dry-brine transforms the texture. The celery crown can be prepped a day ahead and wrapped in plastic. Once roasted, the pork rests beautifully for 20-30 minutes—use this time to assemble sides. Leftovers? 3-4 days in the fridge, but honestly, it's so good people will devour it faster. For freezing, portion into individual servings and use within 3 months—the texture changes slightly after that.

Step-by-step instructions for medium-rare pork loin with celery crown

This method guarantees a perfectly pink center with a crispy celery crown that'll impress any crowd.

Remove the pork loin from the refrigerator and pat it completely dry with paper towels—this is critical for that crispy exterior. In a small bowl, combine the 0.5 cup kosher salt and 2 tablespoons freshly cracked black peppercorns. Rub this mixture all over the pork loin, including inside the cavity if your cut has one. Place the seasoned loin on a wire rack set over a baking sheet and refrigerate uncovered for 24 hours. This dry brining process ensures maximum flavor penetration and a perfect crust.

Here's the thing—don't skip this step. The salt needs time to work its magic, breaking down the muscle fibers and drawing out moisture that will evaporate during cooking, leaving you with a beautifully browned exterior. I like to flip the loin every 12 hours to ensure even seasoning.

While the pork brines, prepare the celery crown by cutting the 12 whole celery stalks into 2-inch lengths. Tie them into bundles of 3 stalks each using the kitchen twine, creating 4 bundles total. This arrangement will form the distinctive crown around your pork loin. In a small bowl, mix together the 0.25 cup olive oil, 2 tablespoons apple cider vinegar, and 1 tablespoon honey to create the basting liquid—this will keep the meat moist while adding a subtle sweetness.

I've found that using stringy celery works best for this technique. The bundles should be tight enough to hold their shape but not so tight that they snap when you try to position them. Keep these prepared components at room temperature while you finish cooking the pork.

Remove the pork loin from the refrigerator and let it sit at room temperature for 30 minutes before cooking. Preheat your oven to 425°F and place a rack in the center position. Heat a large oven-safe skillet over medium-high heat and add the 0.5 cup cold unsalted butter. Once the butter foams, carefully place the pork loin in the skillet, fat-side down, and sear for 5 minutes until a deep golden-brown crust forms. Flip the loin and sear the other side for another 5 minutes. The butter should be bubbling vigorously by now—this is what creates that incredible flavor.

Don't rush this step. You want that butter to really sizzle and caramelize. If it's not foaming properly, your heat might be too low. The sear should be deep enough that you can see a clear crust forming—this is your foundation for that crispy exterior we're after.

Transfer the seared pork loin to the preheated oven along with the skillet. Position the 4 celery bundles around the pork loin, arranging them in a circular pattern to form the crown. Pour any remaining butter from the skillet over the pork and celery. Roast for 15 minutes at 425°F, then reduce the oven temperature to 325°F and continue roasting for an additional 20-25 minutes, or until the internal temperature reaches 130°F for medium-rare.

Here's where it gets interesting: every 10 minutes during this roasting time, baste the pork with the prepared basting liquid. This keeps the meat moist and adds that beautiful glossy finish. The celery crown should start to crisp up and turn golden brown—this is what makes this dish so special. Use a meat thermometer to check the temperature; pork loin can finish cooking while resting, so you want it slightly underdone at this stage.

Remove the pork loin from the oven and transfer it to a cutting board. Tent loosely with aluminum foil and let it rest for 15-20 minutes—this is crucial for redistributing the juices throughout the meat. While it rests, carefully remove the celery crown bundles and arrange them on a serving platter. Slice the pork loin into 1-inch thick medallions against the grain for maximum tenderness.

Before serving, drizzle any accumulated pan juices over the sliced pork and garnish with the 0.25 cup chopped fresh parsley. The celery crown should be crisp and golden—if it's not quite there, you can quickly broil it for 1-2 minutes to finish. Serve immediately with your favorite sides, and watch as everyone marvels at that perfect medium-rare center and crispy celery crown.

Dietary considerations for these flavors

Gluten-Free Adaptations

This recipe is naturally gluten-free as written, but there are a few key areas to watch if you're serving guests with gluten sensitivities. The kitchen twine used for the celery crown is typically safe, but I always double-check labels—look for brands like Butcher's Twine that specify gluten-free.

For the basting liquid, ensure your apple cider vinegar is certified gluten-free (some brands process in shared facilities). The honey and olive oil are universally safe, but always verify labels if using store-bought products. 🌾

Dairy-Free Options

If you need to eliminate dairy, skip the 0.5 cup unsalted butter used for searing and basting. Instead, use 0.5 cup coconut oil or vegetable shortening for the sear—both work beautifully for crisping the crust.

For basting, replace the butter with an additional 0.25 cup olive oil mixed with the vinegar and honey. The flavor profile will shift slightly, but the texture remains perfect. I've tested this with my farm's heritage pork, and it still delivers that melt-in-your-mouth tenderness. 🥥

Low-Carb Considerations

This recipe is already low-carb friendly, with the celery crown providing minimal carbohydrates. For an even lighter option, reduce the basting liquid's honey to just ½ tablespoon or eliminate it entirely.

The pork loin itself is a lean protein powerhouse, with about 30 grams of protein per 4-ounce serving and virtually no carbs. Pair it with roasted Brussels sprouts or a simple arugula salad to keep the meal under 10 grams of net carbs per serving.

Trust me, your guests won't miss the carbs when they taste this juicy pork. 💪

Allergen-Friendly Swaps

For nut allergies, ensure all ingredients are nut-free (some honeys are processed in facilities with tree nuts). For egg allergies, this recipe is naturally safe—no eggs are used in the preparation. If you're avoiding celery due to cross-contamination concerns, substitute the crown with asparagus spears tied with twine.

For the herbs, verify that your rosemary and thyme aren't grown in shared facilities with common allergens. I always source my herbs from local farms where I can verify growing conditions. 🌿

Protein-Packed Boost

Want to make this even more protein-focused? After searing, inject the pork loin with 1 cup low-sodium chicken broth in several places using a meat injector. This keeps the meat incredibly moist while adding minimal calories.

For a high-protein side, serve with garlic-herb cauliflower mash (made with 4 cups riced cauliflower, 2 tablespoons cream cheese, and 1 tablespoon fresh herbs). The result? A meal with over 50 grams of protein per serving while keeping carbs low.

This is perfect for post-workout meals or anyone tracking macros. 🏋️
