For the most tender, juicy results, choose a pork loin roast that:
-
Weighs 2-3 lbs – Good size for even crockpot cooking
-
Has uniform thickness – Cooks evenly without thin ends
-
Is well-marbled – Fat keeps the lean meat moist
-
Has pinkish-red tones – Indicator of freshness
Avoid massive roasts over 3 lbs as they can dry out and won’t cook evenly in the crockpot.
Preparing Pork Loin Roast for the Slow Cooker
Proper prep is key for well-seasoned, tender roast pork:
-
Trim excess fat – Keeps the roast from being greasy
-
Tie with twine – Maintains shape and cooks evenly
-
Season generously – Use a wet marinade or dry rub
-
Refrigerate overnight – Allows flavors to penetrate
-
Sear before cooking – Browning adds tons of flavor
Now your pork loin roast is ready for the slow cooker!

-
Cook fat-side up – Allows fat to baste the meat
