how long to cook pork loin

Cooking pork loin perfectly requires attention to its size, cooking method, and internal temperature to ensure it's juicy and safe. Aim for an internal temperature of 145°F (63°C) for medium doneness, followed by a 3-minute rest. Times vary by oven roasting, grilling, or slow cooking, but reliable sources emphasize using a meat thermometer over strict timers.

Oven Roasting Basics

Roast pork loin at 350-375°F after searing for a crust. For a 3-pound loin, expect 50-60 minutes total, or about 20 minutes per pound. Larger cuts like 5 pounds may take 90 minutes to 2 hours at lower temps like 300°F, basting every 30 minutes. Always check temp early to avoid drying out the lean meat.

Cooking Time Chart

Weight (lbs)| Oven Temp (°F)| Approx. Time| Notes 379
---|---|---|---
2-3| 375| 50-60 min| Sear first, rest 15 min
3-5| 350| 18-28 min/lb| Target 145°F internal
5+| 300-325| 20-25 min/lb| Baste; low/slow for tender

Alternative Methods

• Slow Cooker : 4-6 hours on low for 3-4 lbs until 145°F; great for hands-off meals.

• Grill : Indirect heat at 325°F, 20-25 min per pound, flipping once.

• Air Fryer : 400°F for 20-30 min, turning halfway—quick for smaller loins.

Pro Tips from Forums

Reddit users stress brining overnight for moisture and warn against overcooking past 145°F, as loin dries fast unlike fattier shoulder. Dry-brine 24-48 hours uncovered for crispy skin, then herb-butter baste. Recent 2024 guides highlight reverse-sear for even results.

TL;DR : 20 min/lb at 350°F to 145°F—thermometer is key.
