Before you start
Before beginning, ensure your slow cooker is clean and properly connected to a power outlet. Prepare your workspace by laying out all ingredients, ensuring the pork is removed from the refrigerator about 20 minutes prior to cooking so it does not enter the pot while ice-cold.
Wash the potatoes thoroughly and halve them with a sharp knife on a stable cutting board. Have your melted butter prepared and at room temperature so it pours easily over the roast. Verify that you have enough space on your counter for the slow cooker to operate safely without obstruction near the power cord.
Ingredients at a glance (4)
- 2 lb boneless pork loin
- 1 lb baby red potatoes, halved
- 1 packet savory seasoning packet
- 4 tbsp unsalted butter, melted
Instructions
Preparation and Setup
- Assemble the RoastPlace the boneless pork loin into the base of the slow cooker. Arrange the halved baby red potatoes evenly around the pork loin to ensure they cook through during the long braising process.Look for The pork should sit flat at the bottom of the slow cooker with potatoes surrounding it.Tip Ensure the potatoes are cut to a uniform size so they finish cooking at the same time as the meat.
At this stage, the pork loin is positioned securely in the slow cooker with the halved potatoes arranged artfully around it. The preparation is clean and organized, with all ingredients ready for the seasoning phase.
Check that the potatoes are of a relatively uniform size to ensure they cook evenly and that the pork loin is positioned to allow for maximum contact with the cooking juices during the long, slow braise.
Seasoning and Butter Application
- Season and Add ButterOpen the seasoning packet and sprinkle the contents evenly over the top of the pork loin and the potatoes. Pour the melted butter over the entire mixture, coating the ingredients to provide moisture and flavor as it cooks.Look for The butter should drizzle over the meat and coat the seasoning for even distribution.Tip Use high-quality butter for a richer flavor profile in the final sauce.
The seasoning is now distributed over the surface of the meat and vegetables, and the melted butter has been poured to coat the ingredients. The aroma of the herbs and garlic begins to develop as the butter starts to settle around the base of the roast. Ensure the seasoning covers the entirety of the pork loin and that the butter has reached the bottom of the slow cooker to prevent sticking.
Slow Cooking and Resting
- Slow Cook and RestCover the slow cooker and cook on low for 4 to 6 hours. Once finished, ensure the pork has reached an internal temperature of 145°F (63°C). Remove the pork from the cooker and let it rest for at least 10 minutes before slicing to retain its 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 Resting the meat is essential for ensuring the roast remains succulent and juicy.
The slow cooker is sealed, and the steady heat is working to transform the ingredients. At the end of this phase, the kitchen will be filled with the savory scent of roasted pork and butter. The meat should be tender and the potatoes soft yet intact. Check the internal temperature to confirm it has reached 145°F (63°C) before allowing the roast to rest, which is the final step before slicing and serving.
Common mistakes
Avoid lifting the lid of the slow cooker during the cooking process, as this releases heat and steam, which significantly increases the required cooking time. Another common mistake is adding the butter while it is still boiling hot or solid; ensure it is just melted to allow for even coating.
Finally, do not skip the resting period, as slicing the meat immediately will cause the precious juices to escape, resulting in a drier roast. Always ensure the pork is not touching the heating element directly to prevent burning or uneven cooking.
How to tell it’s done
To determine if the pork loin is cooked, use a digital meat thermometer inserted into the thickest part of the meat. The pork is safe and ready to eat when it reaches an internal temperature of 145°F (63°C). At this point, the exterior should be glossy and the meat should be easily pierced with a fork.
Remember that the pork will continue to rise slightly in temperature while it rests, which is why it is critical to pull it from the heat at the target temperature to avoid overcooking and drying out the roast.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
