Fork-tender slow-cooked pot roast with vegetables in rich gravy is the ultimate family Sunday dinner. This high protein, carnivore-friendly meal practically cooks itself and fills the house with mouthwatering aromas.
Pat the chuck roast dry with paper towels and season all over with 1 tsp salt and black pepper for deep flavor.
Heat olive oil in a large skillet over medium-high heat; sear the roast on all sides until deeply browned, about 4 minutes per side.
Transfer the roast to a slow cooker. Add sliced onions, chopped carrots, cubed potatoes, and chopped celery, arranging around the meat.
In a bowl, whisk beef broth with tomato paste, minced garlic, dried thyme, and rosemary; pour over beef and vegetables.
Cover and cook on LOW for 8–10 hours or until the beef is fork-tender and easily shreds. Baste occasionally if possible.
Once cooked, transfer the roast and vegetables to a platter. Skim fat from the slow cooker liquid, then simmer it in a saucepan to thicken into gravy if desired, adjusting seasoning with extra salt.
