| Boneless Pork Loin Roast 🐖 | 4 lb | Center-cut for even cooking |
| Fresh Rosemary 🌿 | ¼ oz | Finely chopped sprigs |
| Fresh Thyme 🌿 | ¼ oz | Leaves only, stems removed |

| Freshly Ground Black Pepper 🌶️ | 1 tsp | Cracked peppercorns |
| All-Purpose Flour 🌾 | 2 tbsp | For gravy thickening |

The pork loin is the star, so look for center-cut at your butcher or grocery store's meat department—it's more tender and cooks evenly. Whole Foods or Costco often carry excellent quality, but any reputable butcher will have it. Fresh herbs make all the difference here: rosemary and thyme should be vibrant green, not wilted. The celery crown adds that restaurant-worthy crunch, so grab crisp stalks—avoid those with brown spots. For the butter, Plugrá or Land O'Lakes are reliable, but any unsalted will work if it's cold and firm.
No fresh rosemary? Dried at one-third the amount works in a pinch, but it won't have the same aroma. Short on thyme? Fresh oregano is a decent swap, though the flavor profile shifts slightly. The wine can be dry white, but champagne or apple cider add a nice twist. For the celery crown, substitute crisp broccoli florets if needed—just blanch them first for 30 seconds to keep them vibrant. The beef broth should be low-sodium; Swanson or Pacific Foods are solid choices, but homemade is always better if you've got it.
The pork roast keeps best in the fridge for 3-4 days before cooking, wrapped tightly in parchment paper. Once cooked, it reheats beautifully—warm in the oven at 300°F for 15 minutes to maintain moisture. The herb paste and gravy components can be prepped ahead and stored separately for up to 5 days in the fridge. For the celery crown, blanch it in boiling water for 2 minutes before assembling—this ensures it stays crisp after baking. Portion leftovers into containers for easy lunches all week.

Step-by-step instructions for herb-crusted pork loin with celery crown crunch
Here's how to transform a simple pork loin into a showstopping centerpiece with crispy celery crowns and velvety herb gravy.
Prepare the Celery Crown and Herb Paste
Start by trimming the bottom 1 inch from each of the 4 whole celery stalks, creating crowns. Set these aside. In a small bowl, combine the 0.25 oz fresh rosemary, 0.25 oz fresh thyme, 8 cloves minced garlic, 1.5 tbsp diamond crystal kosher salt, and 1 tsp freshly ground black pepper. Add 0.25 cup unsalted butter and mix into a paste using a fork. This herb butter will infuse the pork with incredible flavor.
Spread the herb butter evenly over the entire surface of the 4 lb boneless pork loin roast, pressing it in gently. This ensures the herbs adhere well and create that signature crust. Let the roast sit at room temperature for 30 minutes while you prepare the celery crowns.
Roast the Pork Loin to Perfect Medium Rare
Preheat your oven to 425°F. Place the pork loin on a wire rack set inside a rimmed baking sheet. Arrange the celery crowns around the roast, not touching it directly. Roast for 25 minutes, then reduce heat to 325°F and continue roasting for another 20-25 minutes, or until the internal temperature reaches 130°F for medium rare.
The celery crowns will develop a beautiful golden brown color and crispy texture as they roast alongside the pork. Use a meat thermometer to check the internal temperature—this is the most reliable way to ensure perfect doneness. The pork should feel firm but still slightly springy to the touch.
Rest and Slice the Pork Loin
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 minutes. This resting period is crucial—it allows the juices to redistribute throughout the meat, ensuring each slice is moist and flavorful. During this time, keep the celery crowns warm in the oven at 200°F.
Slice the pork loin into ½-inch thick slices against the grain. The herb crust should be intact and slightly crispy, with the meat inside remaining juicy and pink in the center. Arrange the sliced pork on a serving platter, keeping the celery crowns separate for garnish.
Create the Herb-Infused Gravy
Place the same rimmed baking sheet with the pork drippings on the stovetop over medium heat. Add the celery crowns and let them crisp for 2 minutes until golden brown. Remove the celery crowns and set them aside for garnish. Sprinkle 2 tbsp all-purpose flour over the drippings and stir for 1 minute to cook off the raw flour taste.
Pour in 1 cup beef broth and 0.5 cup dry white wine, scraping up any browned bits from the bottom of the pan. Simmer for 5 minutes until the sauce has thickened slightly. Reduce heat to low and stir in 0.25 cup heavy cream, allowing it to warm through without boiling. Season with additional salt and pepper if needed.
Serve with Celery Crown Crunch and Gravy
Arrange the sliced pork loin on a serving platter, drizzle generously with the herb-infused gravy, and scatter the crispy celery crowns on top. The celery crowns add a delightful textural contrast with their crispy exterior and tender interior. Serve immediately with your choice of sides, such as roasted potatoes or a fresh green salad.
Each bite should deliver a harmonious blend of flavors—herb-infused pork, rich gravy, and the satisfying crunch of the celery crowns. This dish is perfect for special occasions or when you want to impress your guests with a restaurant-quality meal made at home.
Pro Tips For Making 4 Lb Boneless Pork Loin Roast
- USE A MEAT THERMOMETER: I learned this the hard way—pork loin can go from perfect to dry in seconds. Aim for 145°F internal temp (150°F if you like it extra tender), and pull it out before it hits 150°F. That last 5°F jump is where it turns rubbery.
- CHOP CELERY SMALLER THAN YOU THINK: My grandmother swore by this, and she was right: tiny celery dice (1/8-inch or less) caramelize faster and blend into the herbs instead of sitting like sad, crunchy bits. Use the fine side of a box grater if you’re lazy—it’s foolproof.
- SALT THE PORK TWICE: First, dry the roast thoroughly with paper towels, then hit it with 1 tsp kosher salt per pound 2 hours before cooking. Right before roasting, add another ½ tsp per pound—this double salting keeps the crust crisp without over-salting the center.
- ROAST AT 325°F, NOT HIGHER: After burning three batches at 375°F, I finally figured out: pork loin cooks fast, but high heat = tough exterior, dry interior. 325°F gives you time to sear it first (in a hot pan with butter and garlic) and finish it low and slow—no regrets.
Wine and beer pairings for 4 lb boneless pork loin roast
White Wine Pairings
For this herb-infused pork loin, I always reach for a crisp, dry white wine like Sauvignon Blanc from New Zealand or Vermentino from Italy. The bright acidity cuts through the richness of the pork and complements the rosemary and thyme.
A Chablis from Burgundy works beautifully too—its steely minerality balances the dish's herbal notes. 🍷
Red Wine Options
If you prefer red, a light-bodied Pinot Noir from Oregon or Northern Italy is perfect. The delicate fruit flavors won't overpower the pork's herb crust, and the acidity keeps the palate fresh. Avoid heavy reds like Cabernet Sauvignon—they can clash with the delicate celery crowns and gravy.
Beer Pairings
A Belgian Witbier like Hoegaarden or Stella Artois is my go-to beer pairing. The citrusy coriander notes in these beers mirror the herbs in the dish, while the effervescence cleanses the palate between bites.
For a darker option, try a German Helles Lager—its malty sweetness complements the caramelized celery crowns.
Non-Alcoholic Choices
For a refreshing non-alcoholic option, sparkling apple cider or ginger beer works wonders. The effervescence and slight tartness enhance the pork's flavors without competing. I also love serving this dish with a cucumber-mint infused water—it's light, refreshing, and keeps the meal feeling balanced.
Pro Tips for Pairing
Serve your wine or beer slightly chilled—around 50-55°F for whites and 45-50°F for beers. This enhances their aromas and flavors, making each sip complement the dish even more.
If you're unsure, always opt for a wine or beer with bright acidity—it's the key to balancing the richness of the pork.

Frequently asked questions
What's the best way to keep my pork loin from drying out?
Use a meat thermometer to pull it at 130°F for medium-rare—any hotter risks dryness. The herb butter crust helps lock in moisture, and resting for 15 minutes after roasting redistributes juices. For extra insurance, brining in ¼ cup salt per quart of water for 1 hour before cooking works wonders.
Can I substitute the celery crown for something else?
Try crispy broccoli florets (blanched first) or lemon slices> for a citrusy twist. For a sweeter option, use caramelized apple slices>—just reduce oven time to 15 minutes at 375°F to prevent burning. The key is maintaining that textural contrast.
How do I adjust cooking time for a different weight pork loin?
Calculate 20 minutes per pound at 325°F after the initial 25 minutes at 425°F. For example, a 3-lb roast> would need 15 minutes at 325°F. Always use a thermometer—130°F for medium-rare, 145°F for medium.
What's the secret to perfect herb-infused gravy?
Deglaze the pan thoroughly after removing the pork—those browned bits (fond) are flavor gold! Use dry white wine> instead of water for depth, and whisk in the heavy cream> off the heat to prevent curdling. Simmer just until slightly thickened—overcooking makes gravy tough.
Can I make this ahead of time?
Yes! Prep the herb paste and celery crowns 1 day ahead>. Cook the pork 2 days ahead>, then refrigerate tightly wrapped. Reheat slices in a 350°F oven> for 10 minutes>, then drizzle with fresh gravy. The celery crowns crisp best when reheated at 400°F> for 5 minutes>.
