Layer the bottom of the crockpot with diced onions, green onions, minced garlic, and butter. Sprinkle with the Lipton Onion Soup Packet.
Cut slits in the roast on both sides. Generously season with salt, pepper, Badia, garlic powder, Montreal steak seasoning, and Worcestershire sauce. Place the roast on top of the onion bed.
Add peeled carrots and potatoes around the roast. Pour in beef gravy, cream of mushroom soup, and beef stock.
Top with fresh thyme, rosemary, and sage. Cover and cook on high for 6-8 hours until the roast is tender.
Serve with potatoes, carrots, and the mushroom gravy. Enjoy!
