Sear the Beef: Season roast with salt and pepper. In a Dutch oven over medium-high heat, add olive oil. Sear roast on all sides until browned, then remove and set aside.
Sauté Veggies: In the same pot, add onions, garlic, carrots, and celery. Cook until softened, about 5 minutes.
Add Liquids & Herbs: Stir in tomato paste, then pour in beef broth and Worcestershire sauce. Add the roast back into the pot along with rosemary and thyme.
Braise: Cover and simmer on low for 3–3.5 hours or until meat is fork-tender.
Make Mashed Potatoes: Boil potatoes until fork-tender (15–20 mins). Drain, then mash with milk, butter, salt, and pepper until creamy.
Serve: Plate mashed potatoes and top with shredded pot roast and a generous spoonful of braising liquid.
