Ingredients
Method
- Pat the roast dry and season it all over with the salt and pepper.
- Heat the oil in a large skillet over medium-high heat. Sear the roast for 4 to 5 minutes per side, until deeply browned. Move it to a 6-quart or larger slow cooker.
- Lower the heat to medium. Add the onion and garlic to the skillet and cook for 3 minutes. Stir in the tomato paste for 1 minute, then pour in the broth and Worcestershire sauce and scrape up the browned bits.
- Arrange the potatoes and carrots around the roast. Pour the skillet mixture over the top and tuck in the thyme and bay leaves.
- Cover and cook on LOW for 8 to 9 hours or on HIGH for 5 to 6 hours, until the beef pulls apart easily with a fork.
- Lift the beef and vegetables onto a platter and discard the herbs. Skim the fat from the cooking liquid.
- Pour the liquid into a saucepan and bring it to a simmer. Stir the cornstarch into the cold water, whisk it into the liquid and simmer for 2 minutes, until thickened. Season to taste and serve the gravy over the roast.
Notes
Do not skip the sear. Browning the roast first gives the gravy its deep, savory flavor.
