Before you start
Before starting, ensure your slow cooker is clean and placed on a flat, heat-resistant surface. Remove the pork loin from the refrigerator about 20 minutes before cooking to take the chill off, but do not leave it out for longer than 30 minutes.
Prepare the onions by peeling and slicing them into uniform rings. Have your Dijon broth measured and ready in a glass container. Ensure your meat thermometer is calibrated and accessible, as it is the most reliable way to monitor the cooking progress and confirm the final temperature.

- 3 lb pork loin roast
- 2 large sweet onions, sliced
- 1 packet onion soup mix
- 1 cup Dijon broth
Instructions
Layering the ingredients
- Prepare the slow cookerPlace the pork loin roast into the bottom of the slow cooker. Ensure the meat is positioned centrally to allow for even heat distribution during the long cooking process.Look for The pork should sit flat on the bottom of the cooker.Tip Avoid overcrowding the slow cooker if using a smaller model.
- Add aromaticsScatter the sliced sweet onions evenly over the top of the pork loin. This ensures the onions soften and infuse the meat with their flavor as the juices release.Look for The onions should cover the surface of the meat.Tip Slice the onions into uniform rings for even cooking.
At the end of this phase, the pork is properly positioned in the slow cooker with a layer of fresh onion rings on top. Check that the pork is stable and that the onions are distributed evenly to ensure they will soften properly during the cooking process.
Adding the seasoning and broth
- Season and pourSprinkle the onion soup mix packet over the onions and pork. Pour the Dijon broth over the entire mixture, ensuring the seasoning is well-distributed throughout the liquid.Look for The liquid should partially submerge the meat.Tip Ensure the seasoning is not clumped in one area.
The pork and onions are now coated with the onion soup mix and the Dijon broth. Confirm that the seasoning is evenly spread and that the broth has been poured around the meat, creating the necessary liquid base for the slow cooking environment.
Slow cooking and resting
- Slow cook and serveCover and cook on low for 8 hours until the pork reaches an internal temperature of 145°F (63°C). Once finished, remove the pork to a cutting board, let it rest for 10 minutes, and slice it to serve with the onions.Look for The pork is tender and pulls away easily with a fork.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Always verify the internal temperature with a calibrated thermometer.
The pork has reached a tender consistency and an internal temperature of 145°F (63°C). After resting, the meat should be easy to slice. Ensure the onions are soft and glossy, and that the sauce has reduced slightly into a flavorful, savory gravy.
Common mistakes
A common mistake is lifting the slow cooker lid too frequently, which releases heat and steam, significantly increasing the cooking time and potentially drying out the pork. Another error is failing to use a meat thermometer, which can lead to overcooking the roast into a tough, dry texture.
Ensure you do not add too much extra liquid, as the onions and pork will release their own juices during the long cooking process. Finally, ignoring the resting time after cooking will result in a loss of moisture when the meat is sliced.
How to tell it’s done
The pork is done when it reaches a safe internal temperature of 145°F (63°C). Use a meat thermometer inserted into the thickest part of the roast to verify this. The meat should be tender to the touch, and the juices should run clear.
Because the pork continues to cook slightly after being removed from the heat, pulling it out when it reaches the target temperature is crucial.
Allowing the roast to rest on a cutting board for at least 10 minutes helps the juices redistribute, ensuring every slice remains moist and flavorful.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
