Instructions

    Cup of Yum
  1. Season beef chuck pot roast on both sides with salt and pepper. Add oil to skillet and sear both sides of the beef chuck pot roast until browned, about 4-5 minutes per side.
  2. Spray inside of 6-quart slow cooker with cooking spray. Place onions in the bottom of slow cooker then top with seared roast and pour in the pepperoncini juice. Sprinkle the ranch dressing mix and au jus gravy mix over the top of the roast. Add the pepperoncini peppers and sliced butter on top of the roast.
  3. Cover and cook on Low for 8-10 hours or on High for 4-6 hours, or until the roast is fork-tender.
  4. The gravy is a loose gravy, spooned over the top at serving. If you prefer a thicker gravy, mix one tablespoon of cornstarch with one tablespoon of water, then whisk it into the drippings. Let it cook for about 10 minutes or until thickened to your liking.
  5. Shred meat with forks and slice pepperoncinis or leave whole. Serve over mashed potatoes or noodles of choice.
