Instructions

Season and sear beef:
Pat the beef chuck roast dry and season all sides with salt and pepper. In a large skillet, heat olive oil over medium-high. Sear the roast on all sides until browned (about 3 to 4 minutes per side). Transfer to the slow cooker.
Add vegetables:
Arrange onion, garlic, carrots, and celery around the roast in the slow cooker.
Prepare gravy mix:
In a bowl, whisk together beef broth, tomato paste, Worcestershire sauce, thyme, rosemary, and bay leaves. Pour over the roast and vegetables.
Slow cook:
Cover and cook on low for 8 hours, or until the beef is fork-tender.
Make mashed potatoes:
About 40 minutes before serving, place peeled potato chunks in a large pot and cover with cold water along with 1 tsp salt. Bring to a boil, reduce heat, and simmer until very tender (15 to 20 minutes). Drain well, return potatoes to the pot, add butter and milk, and mash until smooth and creamy. Season with salt and pepper. Add more milk for desired creamy consistency.
Rest and shred beef:
Remove the roast from the slow cooker and let it rest for 5 minutes. Discard bay leaves, then shred or slice the beef as desired.
Serve:
Plate mashed potatoes, top with pot roast and vegetables, drizzle with pan juices, and garnish with fresh parsley if desired.
