Ingredients for 5 lb boneless pork loin roast
The secret to this showstopping pork roast lies in these carefully chosen ingredients—each playing a crucial role in crispy perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Pork Loin Roast 🐖 | 5 lb | Center-cut for tenderness |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for rub |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, finely (not coarse) |
| Fresh Thyme 🌿 | ⅛ cup | Leaves only, stems removed |
| Fresh Garlic 🧄 | 6 cloves | Minced, not pressed |
| Diamond Crystal Kosher Salt 🧂 | 2 tbsp | Coarse grain preferred |
| Freshly Ground Black Pepper 🌶️ | 1 ½ tsp | Cracked peppercorns |
| Celery Sticks 🥬 | 12 whole | Trimmed, 2-inch lengths |
| All-Purpose Flour 🌾 | ¼ cup | For gravy thickening |
| Beef Stock 🍲 | 1 cup | Homemade or quality store-bought |
| Dry White Wine 🍷 | ½ cup | Sauvignon Blanc preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Fresh Parsley 🌿 | ⅛ cup | Chopped, for garnish |
The pork loin is non-negotiable here—center-cut is the gold standard for tenderness, and 5 lbs ensures generous servings. Grab it from Costco or your butcher's counter for the best quality; look for even marbling and a vibrant pink color. Fresh herbs make all the difference—Whole Foods or Trader Joe's carry the best rosemary and thyme, but your grocery store's produce section works too. Just make sure they smell fragrant and aren't wilted. For the garlic, peel and mince fresh—jarred minced garlic lacks the punch. And trust me on the Diamond Crystal kosher salt: it dissolves perfectly and has that clean, bright flavor you can't get with table salt.
No fresh rosemary? Dried works at half the amount, but it won't have the same aroma. Running low on wine? Dry chicken broth with a splash of lemon juice mimics the acidity beautifully. The celery crown can be made with carrot sticks if you're out, but celery gives that perfect crispy texture. For the gravy, store-bought beef stock is fine—just avoid the low-sodium kind. The white wine adds brightness, but if you're skipping it, extra lemon juice keeps the flavor profile sharp. And if you're watching calories, half-and-half replaces the heavy cream without sacrificing too much richness (though I won't judge if you use the full-fat version—it's worth it).
The pork roast reheats beautifully—350°F for 15 minutes is all it takes. Wrap leftovers tightly and store for up to 4 days in the fridge, or freeze for 3 months for later feasts. The celery crown loses crispiness after a day, so make it fresh if you're not serving immediately. For the gravy, make a double batch—it freezes perfectly and elevates any dish. I always keep a jar in the fridge for quick pan sauces. And if you're planning ahead, prep the herb butter rub and celery crown the night before—just keep them separate in the fridge until ready to use.

Step-by-step instructions for 5 lb boneless pork loin roast with herb butter gravy
Here's how to transform a simple pork loin into a showstopping centerpiece with crispy celery crowns and velvety herb butter gravy.
Create the Herb Butter Rub and Prep the Roast
In a small bowl, combine the 0.5 cup unsalted butter with the 0.25 cup finely chopped fresh rosemary, 0.125 cup fresh thyme leaves, 6 cloves minced fresh garlic, 2 tablespoons Diamond Crystal kosher salt, and 1.5 teaspoons freshly ground black pepper. Mix until the herbs are evenly distributed throughout the butter.
Pat the 5 lb boneless pork loin roast completely dry with paper towels—this is critical for achieving that crispy exterior. Spread the herb butter mixture all over the roast, pressing it into the surface so it adheres well. Let the roast sit at room temperature for 30 minutes while you prepare the celery crowns. This resting time ensures even cooking throughout.
Assemble the Celery Crowns and Sear the Roast
Trim the 12 whole celery sticks to 2-inch lengths and tie them into bundles using kitchen twine, creating 6 even crowns. This arrangement not only looks stunning but also infuses the pork with subtle celery flavor as it roasts.
Preheat your oven to 375°F. Heat a large oven-safe skillet over medium-high heat and add the roast. Sear it on all sides for 2-3 minutes per side until you achieve a deep golden-brown crust. The butter should sizzle and bubble—this is your signal that the crust is forming properly. Transfer the skillet to the preheated oven.
Roast to Perfect Medium-Rare
Roast the pork for 45-50 minutes for medium-rare doneness, or until the internal temperature reaches 140°F when measured with a meat thermometer. The roast should feel firm but still yield slightly to gentle pressure. Remove the roast from the oven and let it rest for 15 minutes before slicing—this resting period is crucial for retaining juices.
While the pork rests, place the celery crowns around it on the same skillet. Return the skillet to the oven for 10-12 minutes until the celery is tender and slightly caramelized. This step adds both visual appeal and complementary flavor to your presentation.
Make the Herb Butter Gravy
After removing the roast, place the skillet with celery crowns back on the stovetop over medium heat. Add the 0.5 cup dry white wine and scrape up any browned bits from the bottom of the pan—this is where all the flavor hides. Simmer for 3-4 minutes until the wine reduces by half.
Stir in the 1 cup beef stock and bring to a gentle simmer. In a small bowl, whisk together the 0.25 cup all-purpose flour and 0.5 cup heavy cream, then gradually whisk this mixture into the simmering liquid. Cook for 5-7 minutes until the gravy thickens to a velvety consistency. Season with additional salt and pepper if needed, then stir in the 0.125 cup chopped fresh parsley just before serving.
Slice and Serve with Celery Crowns
Slice the rested pork loin into 1-inch thick slices against the grain for maximum tenderness. Arrange the slices on a warm platter, placing the celery crowns artfully around the roast. Ladle the herb butter gravy generously over the top and around the platter. The contrast of crispy celery against the tender pork and rich gravy creates a truly memorable presentation.
Serve immediately with roasted vegetables or a fresh herb salad. The combination of crispy celery crowns, herb-infused pork, and velvety gravy makes this dish perfect for special occasions or impressive weeknight dinners.
Pro Tips For Making 5 Lb Boneless Pork Loin Roast
- Sear Before Seasoning: Pat the pork loin completely dry with paper towels—this isn’t just about flavor, it’s about that crisp crust. After searing in butter, pull the pan off heat, let it rest 2 minutes, then sprinkle herbs and garlic while the butter’s still hot. That’s when the aromatics stick like glue.
- Butter Bath, Not Drizzle: Don’t just toss chunks of butter on top—melt 4 tablespoons first, then spoon it generously over the roast mid-cooking. The butter pools in the pan, bastes the meat, and turns into a flavor bomb instead of burning. (Yes, even if you’re impatient like me.)
- Don’t Overcrowd the Herbs: Fresh rosemary and thyme need room to breathe—pack them too tight, and they’ll steam instead of crisp. Strip the leaves from stems, then scatter them loosely over the roast. If you’re skeptical, try it: the difference in aroma is night and day.
- Internal Temp Matters More: Pork loin is forgiving, but 140°F is the magic number—pull it out before it hits 145°F. Let it rest 10 minutes under foil; the carryover heat will push it to perfect medium-rare. (I learned this the hard way—overcooked pork is sad pork.)
Regional styles of this recipe
Southern Carolina Style
In Charleston, we take our pork roasts seriously—this is where I learned to balance sweet and savory flavors. For a Southern twist, add 1 tbsp brown sugar to the herb butter rub and a splash of apple cider vinegar to the gravy.
The vinegar brightens the dish, while the caramelized sugar adds depth. Serve with collard greens and cornbread for a true Lowcountry feast. 🌶️
Georgia Smoky Twist
Back in my Georgia roots, we'd smoke the pork after roasting for that signature Southern flavor. After searing, transfer the roast to a smoker set at 225°F and smoke for 30 minutes with hickory chips.
The smoky aroma pairs perfectly with the herb butter. Top with pickled jalapeños and serve with creamy mac and cheese for a crowd-pleaser. 🔥
Texas-Style Herb Crust
Texans love their crusts, so here's how to elevate yours: After searing, mix 2 tbsp crushed cornflakes with 1 tbsp melted butter and press it onto the roast before roasting. The cornflake crust adds a satisfying crunch while keeping the inside tender.
Pair with sautéed okra and white BBQ sauce for a Texan-inspired meal. This method works beautifully with the celery crowns too. 💫
Midwest Herb Butter Gravy
The Midwest loves rich, hearty gravies—so let's make yours extra velvety. After reducing the wine, add 1 tbsp Dijon mustard to the gravy base for depth. Finish with a pinch of nutmeg and serve with buttery mashed potatoes and roasted Brussels sprouts.
This version feels cozy and comforting, perfect for cold-weather gatherings. ✨
Charleston Market Adaptations
At Charleston's markets, I've seen this dish transformed with local ingredients. Swap the white wine for local peach brandy (if available) for a fruity twist. Use fresh shaved fennel in the celery crowns for a subtle licorice note.
For a seafood touch, add a splash of shrimp stock to the gravy—it's a nod to the coast's influence. These adaptations keep the dish fresh while staying true to its roots. 🌊

Frequently asked questions about your 5 lb pork loin roast
Why does my pork loin turn out dry even when I follow the recipe?
Pork loin can dry out if overcooked or if the meat isn't properly rested. Always use a meat thermometer to check for 140°F internal temp (medium-rare), and let it rest for 15 minutes before slicing. Pat it dry before seasoning too—moisture prevents that perfect crispy crust.
Can I substitute fresh herbs with dried ones?
Yes, but use half the amount of dried herbs (so 1/4 cup dried rosemary instead of 1/2 cup fresh). Dried herbs lose potency during processing. For best flavor, toast dried herbs in a dry pan for 30 seconds before mixing into the butter. The aroma will be more vibrant!
How do I adjust cooking time if my oven runs hot?
If your oven runs 25°F hotter, reduce the temperature to 350°F and add 5-7 minutes to the roasting time. Test doneness with a thermometer—140°F is perfect for medium-rare. For extra insurance, tent loosely with foil after 30 minutes to prevent over-browning.
What's the best way to reheat leftovers?
Slice the pork first, then reheat in a skillet with 1 tbsp butter over medium-low heat for 5-7 minutes until warmed through. For gravy, reheat separately and stir in a splash of cream or stock to restore richness. Never microwave—it makes pork tough.
Can I make this recipe in a slow cooker?
Not ideal for this cut—pork loin benefits from high-heat searing for flavor. However, you could try the herb butter rub, then cook in a 300°F oven for 1.5 hours (covered) until 140°F internal temp. The celery crowns won't crisp as well, but the pork will stay moist. For best results, stick to oven-roasting!
