Sweet Pepper Butter Pork Shoulder: One-Pot Slow Cooker Step-by-step instructions

Before you start

Before starting, pat the pork shoulder dry with paper towels—this helps the seasoning adhere. Slice the bell peppers into thick strips and the onions into thin wedges. Have the butter ready to go.

No need to preheat anything; the slow cooker handles it all. If you plan to serve over mashed potatoes, prepare those ahead of time or while the pork cooks. For a 6-quart slow cooker, the roast should fit comfortably with the vegetables piled around it.

Instructions

Build the Base

1. 1Layer the Pork and Vegetables
   Place the pork shoulder roast in the center of a 6-quart slow cooker. Scatter the sliced red and green bell peppers and the sliced yellow onions over and around the roast. Season everything with the kosher salt and black pepper.
   Look for The roast sits snugly in the pot, surrounded by the peppers and onions.
   Tip If the roast is larger than 4 pounds, trim it to fit or cut it into large chunks.
2. 2Top with Butter
   Unwrap the stick of salted butter and place it directly on top of the seasoned roast. It will melt as the slow cooker heats, basting the meat and vegetables.
   Look for The butter sits on the roast, ready to melt.
   Tip Use cold butter straight from the fridge for easy handling.

At the end of this phase, the pork roast sits in the center of the slow cooker, surrounded by bright strips of red and green peppers and yellow onion slices. The seasoned butter is perched on top, ready to melt.

The raw, fresh aroma of peppers and onions fills the kitchen. Everything looks vibrant and promising. Before moving on, ensure the roast is centered and the vegetables are evenly distributed.

Slow-Cook and Shred

3. 3Slow-Cook Low and Slow
   Cover the slow cooker and cook on LOW for 8 to 10 hours, or on HIGH for 5 to 6 hours, until the pork is fork-tender and easily shreds. The internal temperature should reach at least 145°F (63°C) for safety, but for best shredding, cook until it reaches 195-205°F (91-96°C). Let it rest for 3 minutes before slicing.
   Look for The pork is fall-apart tender and the peppers and onions are very soft.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Do not open the lid during cooking—each peek releases heat and adds time.
4. 4Shred the Pork
   Transfer the roast to a cutting board. Using two forks, shred the pork into bite-sized ribbons, discarding any excess fat. Return the shredded pork to the slow cooker and stir gently to coat with the juices. Let it rest for 3 minutes before slicing.
   Look for The pork shreds easily into moist, tender strands.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip If the pork is not shredding easily, cook for another 30-60 minutes.
5. 5Rest the Meat
   Let the shredded pork rest in the warm slow cooker, off the heat, for at least 3 minutes before serving. This allows the juices to redistribute and the meat to stay moist.
   Look for The meat rests in the buttery juices.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Resting is essential for tender, juicy pork.

After hours on low, the kitchen smells richly of roasted peppers and savory pork. The meat is deeply browned, shrunken, and fork-tender; it shreds into moist ribbons with ease. The peppers and onions have collapsed into a soft, jammy mixture. The jus is golden, glossy, and buttery. Check that the pork reaches at least 145°F (63°C) and that the shredding is effortless before proceeding.

Serve and Savor

6. 6Serve Over Mashed Potatoes
   Spoon the shredded pork, peppers, onions, and the golden buttery jus over a bed of whipped Yukon Gold mashed potatoes, or serve on rolls for sandwiches. Use a slotted spoon to control the amount of jus.
   Look for The pork is piled high, glistening with butter and jus.
   Tip For extra richness, spoon a little extra jus over the top.

The shredded pork is piled on a platter or directly onto mashed potatoes, glistening with buttery jus. The peppers and onions are interspersed throughout, and the aroma is irresistible. The texture is succulent and tender, with a rich, savory-sweet flavor. The jus pools around the base, ready to be spooned over. The dish looks rustic and inviting, perfect for a comforting meal.

Common mistakes

One common mistake is lifting the lid to check on the food—this releases heat and significantly increases cooking time. Trust the process and resist the urge. Another pitfall is using a lean cut like pork loin, which will dry out; stick with shoulder.

Overcrowding the slow cooker can also lead to uneven cooking, so use the right size. Finally, don't skip the resting step after shredding; it lets the meat reabsorb juices, keeping it moist.

How to tell it’s done

The pork is done when it is fork-tender and shreds easily. The internal temperature should be at least 145°F (63°C) for safety, but for optimal tenderness, cook it to 195-205°F (91-96°C). The peppers and onions should be very soft and translucent.

When you insert a fork into the roast, it should twist easily and pull apart without resistance. The juices should be golden and well seasoned. If the pork is still tough, continue cooking and check again in 30-minute intervals.
