Equipment

  • 1 Slow Cooker

Ingredients

  • 3-4 pounds chuck roast
  • 1 stick butter
  • 1 packet au jus gravy mix
  • 1 packet Ranch dressing mix
  • 6 Pepperoncini peppers
  • 1/2 cup Pepperoncini pepper juice

Instructions

  • Sear the Roast: Heat olive oil in a skillet over medium heat. Sear the chuck roast for 4-5 minutes on each side until browned. This step enhances the flavor and texture of the meat.

  • Prepare the Slow Cooker: Place the seared roast in the slow cooker. Pour the pepperoncini pepper juice over the roast, ensuring it’s evenly distributed.

  • Slow Cook: Cover the slow cooker and set it to cook on low for 8 hours. The long cooking time allows the flavors to meld and the roast to become incredibly tender.

  • Shred and Serve: After cooking, shred the meat with two forks and mix it well with the juices. Serve the shredded meat over noodles, mashed potatoes, or piled high on slider buns.

Notes

Don’t skip searing the roast, as it locks in flavors and improves the texture of the meat.
For best results, layer the seasonings evenly to ensure every bite is as tasty as the last.
Adjust the cooking time based on the size of your roast. Larger roasts may require a bit more time to become tender.
