Before you start
Before beginning, ensure your slow cooker is clean and placed on a stable surface away from the edge of the counter. Prepare the pork by ensuring it is evenly coated with mustard, and wash, peel, and chop the potatoes into uniform two-inch pieces.
Slicing the onions into uniform wedges will ensure they soften and incorporate into the sauce perfectly. Have all your ingredients measured and ready to ensure the assembly process is smooth and efficient, allowing for a quick setup before the long, slow cook begins.
Ingredients at a glance (5)
- 2 lb pork roast, mustard-coated
- 2 lb potatoes, peeled and cut into chunks
- 1 large onions, sliced
- 1 cube bouillon cube, crumbled
- 1 cup white wine
Instructions
Assembly Phase
- Assemble the roastPlace the mustard-coated pork roast into the bottom of the slow cooker. Arrange the potato chunks and the sliced onions evenly around the sides of the pork to ensure they cook thoroughly in the juices.Look for The pork should sit flat at the base.Tip Ensure the potatoes are cut to a uniform size for even cooking.
The pork roast should be positioned securely at the bottom of the slow cooker with the vegetables tucked around the sides. Everything should be arranged in a single layer to ensure even heat distribution. Ensure the bouillon is evenly distributed over the top of the ingredients to guarantee consistent seasoning throughout the dish as the liquids begin to integrate during the initial stages of the slow cooking process.
Cooking Phase
- Season and add liquidSprinkle the crumbled bouillon cube over the top of the pork and vegetables. Carefully pour the white wine into the slow cooker, allowing it to pool at the bottom to create a flavorful braising liquid.Look for The liquid should just coat the bottom.Tip Crumb the bouillon thoroughly for better distribution.
During the long cooking phase, the slow cooker will maintain a low, consistent temperature that allows the pork to braise gently. The wine and bouillon will combine with the juices released by the pork and onions to create a fragrant, savory liquid. You should notice the kitchen filling with a rich, savory aroma as the vegetables soften and the flavors meld together perfectly over the eight-hour duration of this phase.
Finishing Phase
- Cook and serveCover the slow cooker and cook on low for 8 hours. Before serving, verify that the pork has reached an internal temperature of 145°F (63°C) using a meat thermometer. Let the meat rest for at least 3 minutes before slicing and serving alongside the tender potatoes.Look for The meat should be tender enough to shred with a fork.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Resting the meat is essential for moisture retention.
At the end of the cooking time, the meat should be exceptionally tender and the potatoes should have reached a buttery, melting consistency. The liquid at the bottom of the cooker should be reduced into a flavorful, aromatic sauce.
Before serving, confirm the internal temperature of the pork has reached 145°F (63°C) and allow the roast to rest briefly to ensure the juices redistribute throughout the meat, resulting in the perfect texture.
Common mistakes
A common mistake is using a cut of meat that is too lean, which can result in a dry roast despite the long cooking time. Always choose a cut with some marbling. Another error is cutting the potatoes into pieces that are too small, as they may turn to mush after eight hours of cooking; aim for larger chunks.
Finally, ensure the slow cooker lid is kept closed throughout the process, as opening it frequently releases heat and significantly increases the total cooking time required.
How to tell it’s done
The pork roast is done when it reaches a minimum internal temperature of 145°F (63°C) when measured with a food thermometer in the thickest part of the meat. You will also notice that the meat is incredibly tender and easily pulls apart with a fork.
The potatoes should be soft enough to be pierced easily with a knife, indicating they have absorbed the cooking liquid and are ready to be served alongside the succulent, flavorful pork.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
