This pork loin center cut roast cooks at 350°F to 145°F with a 3-minute rest for juicy slices—simple rub, quick sear, and an even roast on a rack.
If you want tender, sliceable pork with a crisp crust and a blush center, this method delivers on a standard weeknight or a crowd dinner. We’ll dry-brine for flavor, sear for color, then roast gently to a precise internal temperature. You’ll get clean slices, pan juices for easy gravy, and a repeatable process you can trust.

Pork Loin Center Cut Roast Recipe (Step-By-Step)
Shop & Trim
Choose a meaty center-cut pork loin roast with a thin fat cap. Ask the butcher to remove silver skin if needed. At home, pat the roast dry and square off any ragged edges so browning is even end to end.
Season Early (Dry-Brine)
Salt the roast all over with ½–¾ teaspoon kosher salt per pound. Set it on a wire rack over a tray, uncovered in the fridge for 8–24 hours. This draws salt inward and dries the surface for better browning. Before cooking, rub with 2 teaspoons olive oil and a simple mix: 1½ teaspoons black pepper, 1 teaspoon garlic powder, 1 teaspoon onion powder, ½ teaspoon paprika, and a light pinch of sugar for color.
Sear For Crust
Heat a heavy skillet over medium-high. Add a slick of oil. Sear the roast on all sides until deep golden, about 6–8 minutes total. You’re building flavor on the outside while keeping the interior cool so it cooks evenly in the oven.
Roast To Temperature
Move the seared roast to a V-rack set over a rimmed sheet. Insert a probe into the thickest center. Roast at 350°F. Begin checking at the early end of the time window using the per-pound guide in the table. Pull the roast when it hits 143–145°F in the center.
Rest Briefly, Then Slice
Set the roast on a board and rest for 3 minutes. This brief pause ensures safe service and lets the heat settle so slices stay juicy. Slice across the grain into ½-inch pieces. Spoon warm pan juices over the top.
Why This 145°F Method Works
This cut is lean with a tight grain. Cooking hot and fast can dry it out before the center finishes. A steady 350°F roast gives you an even gradient edge to center. The sear adds browned flavor without overcooking the core. Finishing at 145°F hits the sweet spot for tenderness while meeting food-safety guidance. For official doneness guidance on whole pork roasts, see the FSIS safe temperature chart and the update that set pork to 145°F with a short rest, covered in the USDA temperature announcement.
Center Cut Pork Loin Roast Recipe Variations (Weeknight To Holiday)
Herb-Garlic Crust
Mix 2 teaspoons chopped rosemary, 2 teaspoons chopped thyme, 3 minced garlic cloves, and 1 tablespoon Dijon. Rub after the dry-brine, before searing. The herbs perfume the pan drippings for a quick gravy.
Maple-Mustard Glaze
Whisk 2 tablespoons maple syrup, 1 tablespoon Dijon, 1 teaspoon apple cider vinegar, and a pinch of pepper flakes. Brush on during the last 15 minutes of roasting so it sets without burning.
Spice-Rubbed (Smoky)
Combine 1 teaspoon smoked paprika, ½ teaspoon ground cumin, ½ teaspoon coriander, ½ teaspoon black pepper, and ¼ teaspoon cayenne. Toast the spices briefly in the pan after searing, then roast. The aroma blooms and carries into the meat.
Stuffed & Tied
Butterfly the roast into a flat sheet, spread a thin layer of sautéed spinach, mushrooms, and feta, roll tightly, and tie every 1½ inches. Sear the rolled roast and roast to the same internal temperature. Slices show a spiral and plate beautifully.
Timing, Doneness & Thermometer Tips
How Long To Roast
Plan roughly 20–26 minutes per pound at 350°F once the roast is seared and in the oven. Thickness and starting temperature cause wide swings, so the thermometer rules. Begin spot checks early and watch the final 10 minutes closely.
Probe Placement
Insert the probe into the center from one end, staying clear of the pan. If the roast is tapered, aim for the thicker half. For spot checks, use an instant-read in two places to confirm the lowest reading is at least 145°F after the brief rest.
Pull Temperature & Rest
Pull at 143–145°F and rest 3 minutes. If you prefer a slightly firmer slice, let it drift to 150°F in the oven, then rest. Avoid overshooting; the loin is lean and dries fast above 155°F.
Pan Sauce You Can Make While It Rests
Quick Skillet Gravy
Set the searing skillet over medium. Pour off excess fat, leaving browned bits. Add ½ cup dry white wine or low-sodium broth and scrape. Reduce by half. Stir in ½ cup more broth and 1 teaspoon Dijon. Simmer 2–3 minutes. Swirl in 1 tablespoon butter to finish. Season with salt and pepper to taste.
Apple-Onion Jus
Sauté ½ sliced onion in a teaspoon of oil until soft. Add ½ cup apple cider and a splash of vinegar. Reduce until syrupy, then stir in resting juices. Great with the maple-mustard glaze variation.
Sides That Match The Roast
Keep sides crisp and bright to contrast the rich meat. Try roasted carrots with thyme, garlicky green beans, buttered baby potatoes, or a tart slaw with shaved fennel and apple. A sharp mustard or horseradish cream adds lift.

Make-Ahead, Leftovers & Reheating
Make-Ahead
Salt the roast the day before. Mix your rub and set out your rack and pan. Sear just before roasting for the best crust.
Leftovers
Chill slices in a shallow container with pan juices to keep them moist. For sandwiches, slice cold and rewarm only what you’ll eat.
Reheat Without Drying
Set slices in a small skillet with a spoon of broth. Warm over low heat, covered, 3–5 minutes, just to steaming hot. Avoid boiling.
Troubleshooting & Pro Tips
Edges Are Dry, Center Is Done
Lower the oven to 325°F next time and begin checks earlier. Use a rack so heat circulates.
Center Isn’t At 145°F But Crust Is Dark
Tent loosely with foil and keep roasting. The foil slows browning while the center finishes.
Roast Cooks Too Fast
Start with a cooler oven (325°F) after the sear. The per-pound timing is a guide; thickness rules.
No Probe Thermometer?
Use an instant-read and check two spots. When the lowest spot reads 145°F after the 3-minute rest, you’re ready to slice.
The Science In Short
Dry-brining seasons to the core and dries the surface so browning starts fast. Searing triggers flavorful browning on the outside. A steady oven finish keeps the center tender. The 145°F finish with a brief rest is the sweet spot for a loin roast with clean, juicy slices.
Recipe Card
Ingredients (Serves 6–8)
- 1 center-cut pork loin roast, 2–4 lb
- 1–1½ tbsp kosher salt (½–¾ tsp per lb, for dry-brine)
- 2 tsp olive oil
- 1½ tsp black pepper
- 1 tsp garlic powder
- 1 tsp onion powder
- ½ tsp paprika
- Pinch sugar (color)
- Neutral oil for searing
Method
- Dry-Brine: Salt the roast all over. Refrigerate on a rack, uncovered, 8–24 hours.
- Preheat & Mix Rub: Heat oven to 350°F. Stir pepper, garlic powder, onion powder, paprika, and sugar.
- Season: Pat roast dry. Rub with olive oil and the spice mix.
- Sear: Heat a heavy skillet over medium-high with a thin layer of oil. Sear all sides until well browned, 6–8 minutes.
- Roast: Set on a V-rack over a rimmed pan. Insert a probe into the center. Roast until the center reaches 143–145°F, roughly 20–26 minutes per pound.
- Rest & Slice: Rest 3 minutes. Slice across the grain into ½-inch pieces. Spoon over pan juices.
This process keeps flavors bright and texture tender. The thermometer is your north star, and the 145°F finish keeps the pork juicy and safe for the table.
