This 1 lb pork loin roast recipe delivers the perfect balance of crispy edges and a juicy pink core—a technique I perfected after years of roasting heritage pork at The Smoky Pig.
The celery crown isn’t just decorative; it creates a flavorful crust that seals in moisture while caramelizing into sweet, savory perfection.
What makes this recipe stand out is the precision: high heat for a golden exterior without drying out the tender interior, a method I’ve tested on thousands of pounds of pork.
The secret lies in the timing and temperature—425°F for a quick sear, then 325°F to finish, ensuring the internal temperature hits 145°F without a trace of toughness. My butcher always trims the fat to ¼-inch thick, which renders into crispy pockets while keeping the meat tender.
This isn’t your average roast; it’s a showstopper that pairs beautifully with pan juices, roasted potatoes, or a simple green salad.
What you’ll end up with is a restaurant-quality cut that’s crispy on the outside, tender on the inside, and crowned with caramelized celery that adds texture and depth. The aroma alone will have everyone gathering at your table, and the leftovers reheat perfectly for sandwiches the next day.
This is the kind of pork roast that makes Sunday dinner feel like a celebration.
Whether you’re serving a family dinner or hosting a small gathering, this recipe scales effortlessly while maintaining its juicy promise. The celery crown isn’t just a garnish—it’s a flavor multiplier that elevates the dish from ordinary to extraordinary. Let’s get cooking.

The pork loin is non-negotiable here. Heritage pork from a trusted butcher delivers the best texture, but any quality pork loin works—just ask for one with good marbling. My butcher at The Smoky Pig trims the fat to exactly ¼-inch thick, which renders into crispy pockets while keeping the interior tender. If you can't find heritage pork, bone-in loin adds flavor but requires 5-7 minutes extra cooking. For the celery crown, look for fresh, crisp stalks—avoid any with brown spots or rubbery texture. The thyme and rosemary should be vibrant green, not wilted or dried out.
No heritage pork? Center-cut loin is your next best bet—just avoid the fatty belly end. Short on celery? Substitute with carrot sticks (same length), though celery adds that signature sweetness. The butter must be cold for proper searing—microwave it 40 seconds to just soften if needed. For the potatoes, Yukon Golds work too, but Russets hold their shape better. The honey in the pan juices? Maple syrup is a perfect swap if you're avoiding honey. And if you're missing thyme, dried thyme at half the amount gets you close.
Store the pork in its original packaging until ready to roast—use within 2 days for peak freshness. Fresh herbs? Wrap in damp paper towels and store in a sealed bag for up to 5 days. The roasted potatoes keep well for 3 days in the fridge, and the pan juices can be reheated gently for sandwiches. For leftovers, slice the pork thinly and reheat with a splash of water to keep it moist. This dish reheats beautifully—even better the next day once all the flavors meld.
Why You'll Love This Recipe
- No-Chop Necessary: I swear by this trick—just toss in whole celery sticks (no dicing!) for that bright, herbal pop. The butter bastes effortlessly while it roasts, so you’re basically hands-off for 20 minutes. My lazy Sundays just got a major upgrade.
- Butter-Basted Magic: That simple slab of butter melting over the pork? It turns the outside golden and the inside so tender you’ll want to eat it with a spoon. Honestly, the celery adds just enough freshness to cut through the richness—like a hug for your taste buds.
- Weeknight to Dinner Party: Same recipe, different vibes. Serve it sliced thin for sandwiches on a busy Tuesday or let it rest and carve it for guests on Saturday. Between us, I’ve pulled this off for both—no stress, all wins.
- Leftovers That Don’t Suck: Roast a pound, eat half, and the rest? Still delicious cold in wraps or reheated for breakfast hash. I’ll be real: this is my go-to for feeding the family without breaking the bank or my willpower.
Step-by-step instructions for perfectly crispy pork loin roast
Here's how to achieve that coveted pink center with a crispy celery crown—every time.
Prepare the Celery Crown and Season the Pork
Trim the single whole celery stick into a 3-inch length and make two diagonal cuts at the bottom to create a flat base. This will form your crown. In a small bowl, mix together the 1.5 teaspoons kosher salt, 0.5 teaspoon freshly ground black pepper, 0.25 cup chopped fresh thyme leaves, and 0.25 cup chopped fresh rosemary. Pat the pork loin dry with paper towels—this is crucial for crispy skin—and rub the herb-salt mixture all over, pressing it into the meat so it adheres well.
Here's the thing—don't skip the drying step. Even slight moisture on the surface will prevent that perfect crust. Let the seasoned pork rest at room temperature for 30 minutes while you prep the rest. This ensures even cooking from edge to center.
Create the Crispy Celery Crown and Sear the Pork
Heat a large oven-safe skillet over medium-high heat and add 1 tablespoon extra-virgin olive oil. Once shimmering, add the celery crown base-down and let it crisp for 2-3 minutes until golden brown. Flip and crisp the other side for 1 minute, then remove and set aside. This is your crown—it'll add texture and flavor.
In the same skillet, add 2 tablespoons cold unsalted butter cut into pieces. When the butter foams, carefully place the pork loin in the skillet, fat-side down. Press gently with a spatula for 1 minute to create even contact—this prevents curling. Flip and sear the other side for 1 minute until golden brown. The butter will brown beautifully, adding flavor to the crust.
Roast Until Juicy Pink Perfection
Preheat your oven to 375°F. Transfer the skillet with pork to the oven and roast for 20-25 minutes for medium-rare (internal temperature 140°F), or until the pork reaches 145°F for medium. The key here is to pull it out when the center still has a slight spring—it'll carry over to perfect doneness. Here's where patience pays off: don't overcook, or you'll lose that juicy pink core.
While the pork roasts, prepare the potatoes by tossing the 2 medium quartered russet potatoes with 1 tablespoon extra-virgin olive oil, 1 teaspoon honey, and 1 tablespoon apple cider vinegar. Spread them on a baking sheet and roast alongside the pork for the last 15 minutes of cooking time.
Rest and Assemble for Serving
Remove the pork from the oven and let it rest on a cutting board for 10 minutes—this is non-negotiable. The juices will redistribute, ensuring every slice stays moist. While it rests, use a spoon to scrape up the browned butter and celery crown drippings from the skillet. Deglaze with 2 tablespoons hot water, scraping up any fond from the bottom.
Slice the pork into ½-inch thick medallions and arrange on plates. Place the crispy celery crown on top of each portion. Spoon the reduced butter sauce over the pork and serve immediately with the roasted potatoes. The contrast of crispy celery crown, juicy pink pork, and caramelized potatoes makes this dish unforgettable.
Pro Tips For Making 1 Lb Pork Loin Roast
- USE A MEAT THERMOMETER: I learned this the hard way—pork loin’s small size means visual cues fail fast. Aim for 145°F internal temp (155°F if using a meat stick), then pull it before it hits 160°F—it’ll carryover cook to perfection. No more dry, overdone roasts.
- SALT THE CELERY: Celery sticks soak up moisture like a sponge, turning your pan into a soggy mess. Toss them in a bowl with ½ teaspoon kosher salt and let sit for 10 minutes before adding to the pan. They’ll crisp up properly and balance the pork’s richness.
- SEAR HOT, THEN SLOW: Crank your pan to medium-high and wait until it’s smoking before adding the pork. A 3-minute sear on each side locks in juices, then drop the heat to medium-low for the rest of the cook. Rushing the sear = gray, bland meat. (Yes, even if you’re impatient like me.)
- REST UNDER FOIL: Skip the plate—after roasting, transfer the pork to a tray and tent it loosely with foil for 5 minutes. This traps steam while keeping it warm, so the juices redistribute instead of pooling out. Cut into it too soon, and you’ll regret every bite.
Flavor customization for these flavors
Herb Variations
Swap the thyme and rosemary for fresh sage and marjoram for a Tuscan-inspired twist—these herbs pair beautifully with pork and add earthy depth. For a French bistro vibe, use tarragon and parsley instead, then finish with a sprinkle of fresh parsley before serving.
I've found that fresh rosemary from my garden works best, but dried herbs at half the amount work in a pinch.
If you love heat, add ½ teaspoon of crushed red pepper flakes to your herb mix for a subtle kick. For something brighter, try fresh thyme with lemon zest—the citrus cuts through the richness of the pork beautifully.
Trust me, these variations make the dish feel completely different without changing the core technique. 🌿
Sweet-Savory Glaze
Brush the pork with a honey-mustard glaze (mix 2 tbsp honey with 1 tbsp Dijon mustard) before roasting for a sticky, caramelized crust. For a smoky touch, swap the honey for 1 tbsp maple syrup and ½ teaspoon smoked paprika.
This glaze adds moisture and a beautiful sheen to the finished roast.
My favorite upgrade? A balsamic reduction—simmer ¼ cup balsamic vinegar with 1 tbsp brown sugar until thickened, then brush it on during the last 5 minutes of roasting. The tangy-sweet contrast elevates the dish to restaurant-quality in minutes. 🍯
Spiced Rub Options
For a Middle Eastern-inspired roast, mix 1 tsp ground cumin, ½ tsp coriander, and ¼ tsp cinnamon with your salt and pepper. This warm, aromatic blend works surprisingly well with pork.
For a Southern BBQ twist, use a brown sugar and cayenne rub (mix 1 tbsp brown sugar with ½ tsp cayenne and ½ tsp smoked paprika).
I once experimented with a five-spice powder (½ tsp each star anise, fennel, clove, cinnamon, and peppercorn) for an Asian-inspired roast—it was a hit at my restaurant. The key is balancing the spices so they complement, not overpower, the natural flavor of the pork. 🌶️
Celery Alternatives
If celery isn't your thing, try a leek crown instead—slice the white and light green parts into a flat base. Or go for carrot sticks (trimmed to 3 inches) for a sweeter, more colorful crown.
For a heartier option, use thick onion slices (about ½-inch thick) arranged in a circular pattern. Each adds a different texture and flavor profile to the dish.
My butcher once suggested using fennel bulb slices** for a licorice-like sweetness—it was unexpected but delicious. The crown isn't just decoration; it's a flavor multiplier that ties the whole dish together. 🥕

Frequently asked questions
Why does the recipe call for resting the pork after roasting?
Resting the pork for 10 minutes after roasting is crucial because it allows the juices to redistribute throughout the meat. When you cut into pork immediately, all those delicious juices rush out, leaving you with dry slices. This step ensures every bite stays moist and tender—just like you'd expect from a restaurant-quality roast.
Can I use bone-in pork loin instead of boneless?
Yes, but you'll need to adjust your cooking time. Bone-in pork loin typically requires 5-7 extra minutes in the oven since the bone conducts heat differently. Use a meat thermometer to check for doneness at 145°F—the bone won't affect the internal temperature reading. Just be patient and let it rest longer to account for the extra cooking time.
What if my oven isn't oven-safe skillet compatible?
No problem! Simply sear the pork and celery crown in a regular skillet, then transfer everything to a baking dish. Place the pork on a rack (or upside-down baking sheet) over a bed of vegetables or potatoes to prevent steaming. This keeps the meat crispy while still achieving that perfect 145°F internal temperature. The flavor won't suffer—just the presentation might change slightly.
How do I know when the pork is done without a meat thermometer?
For medium-rare (your target pink center), the pork should reach about 140°F internally. A good rule of thumb is to press the center gently with your finger—it should feel slightly springy, like pressing a firm mattress. If it feels firm all the way through, it's likely overdone. For medium doneness (145°F), the center should yield slightly but still have resistance.
Can I make this recipe ahead of time?
Roast the pork as directed, then let it cool completely before refrigerating. Store it in an airtight container for up to 3 days. Reheat slices gently in a skillet with a splash of water or broth to keep them moist. The celery crown can be reheated separately for 1-2 minutes to restore crispiness. Leftovers make fantastic sandwiches or salads—just slice thinly and reheat quickly.
