Before you start
Before you begin, ensure your slow cooker is clean and placed on a stable, heat-resistant surface near an electrical outlet. Take your pork loin out of the refrigerator about 20 to 30 minutes before you are ready to start cooking to take the chill off, which helps with a more even cooking process.
Gather all your dry seasoning packets and ensure your butter is sliced into uniform pieces for even melting. Have your pepperoncini ready to go, and prepare a clean cutting board for slicing the finished roast once it has rested.

Instructions
Preparation
- Prepare the PorkPlace the boneless pork loin roast into the ceramic insert of your slow cooker. Ensure the meat is centered and lying flat to promote even cooking throughout the process.Look for The pork loin should sit flat at the bottom of the slow cooker insert.Tip Pat the pork dry with paper towels before placing it in the cooker for better browning.
The pork loin should be positioned in the center of the slow cooker insert, lying flat and stable. The surface of the meat should be relatively dry to ensure the seasonings adhere well. Check that your slow cooker is plugged in and ready to be set to the appropriate heat level.
Everything should be arranged so that you can quickly add the seasonings and butter without unnecessary delay, keeping the kitchen area clean and organized before the cooking process begins.
Seasoning
- Add Seasonings and ButterTuck the whole pepperoncini peppers around the sides of the pork loin. Sprinkle the ranch seasoning and the au jus seasoning mix evenly over the top of the meat. Finally, place the butter slices across the surface of the pork.Look for The seasonings should cover the top of the roast, and the butter slices should be distributed evenly.Tip Do not stir the ingredients; let the slow cooker do the work as the butter melts.
At this stage, the pork is covered with the ranch and au jus seasoning powders, and the butter slices are neatly arranged across the top. The pepperoncini are tucked into the sides of the roast. The slow cooker should now be covered with the lid to begin the heat-transfer process. Ensure that the lid fits snugly to trap the moisture and heat, which are essential for creating the tender, braised result that defines this savory Mississippi-style pork dish.
Cooking and Resting
- Slow Cook and ServeCover the slow cooker and cook on low for 6 to 8 hours, or on high for 3 to 4 hours. Once the pork reaches an internal temperature of 145°F (63°C), turn off the cooker. Let the roast rest for 5 minutes before slicing it into thick pieces and serving with the buttery cooking juices.Look for The pork is done when it is fork-tender and reaches the required internal temperature.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Use a meat thermometer to ensure the pork is safe to consume.
The pork is finished when it is tender, moist, and reaches the safe internal temperature of 145°F (63°C). The kitchen should smell savory and slightly tangy from the pepperoncini and seasonings. Check the temperature, then turn off the heat and allow the roast to rest undisturbed for 5 minutes. This resting time is vital for locking in the juices before you slice the roast, ensuring the final presentation is as high-quality as the flavor profile.
Common mistakes
A common mistake is overcooking the pork loin, which can lead to a dry, stringy texture even in a slow cooker. Always rely on a meat thermometer rather than just the clock, as cooking times can vary based on the specific model of your slow cooker.
Another error is adding too much salt; since both the ranch and au jus packets are quite salty, there is rarely a need for additional seasoning. Finally, avoid lifting the lid frequently, as each time you open the cooker, heat escapes and increases the total cooking time.
How to tell it’s done
The pork is perfectly done when it reaches an internal temperature of 145°F (63°C) as measured by a meat thermometer inserted into the thickest part of the roast. At this stage, the meat should be very tender and easily pierced with a fork.
It is crucial to let the pork rest for at least 5 minutes after removing it from the slow cooker; this resting period allows the juices to redistribute throughout the meat, ensuring every slice remains succulent and flavorful when served.
