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.
