Season the roast generously with salt and pepper.
Sear the meat in olive oil over medium-high heat until browned on all sides.
Place the roast in the slow cooker and sprinkle with dry onion soup mix.
Add water, carrots, potatoes, onion, and celery around the roast.
Cover and cook on low for 8 hours (or high for 4-5 hours) until the meat is tender.
Shred or slice the roast, mixing it with the flavorful juices.
Serve hot, with vegetables and the rich, slow-cooked gravy.
Enjoy with your favorite sides like bread, coleslaw, or a light salad.
