Instructions

Prepare Vegetables: In a 6-quart slow cooker, add the peeled and cut potatoes, carrots, and thyme sprigs. This will create a flavorful base that absorbs the juices released during cooking.
Season Beef: Pat the chuck roast dry with paper towels. Season all sides evenly with 1½ teaspoons salt and 1 teaspoon black pepper to enhance natural flavors and ensure a good sear.
Brown Surface: Heat a large skillet over medium-high heat and add olive oil. Once hot, sear the beef for about 5 minutes on each side until golden brown. Transfer the browned roast to the slow cooker, reserving the pan and drippings for the next step.
Sauté Aromatics: In the same skillet over medium heat, add onions and sauté until lightly golden and tender, about 2 minutes. Stir in garlic and cook for 30 seconds. Add balsamic vinegar and cook until it reduces and coats the onions, about 1 minute. Stir in tomato paste and cook for another minute, then transfer this mixture to the slow cooker.
Make Pan Sauce: Over medium-high heat, melt butter in the skillet. Whisk in flour and cook for 30 seconds to form a roux. Gradually whisk in beef stock, bringing the mixture to a simmer until thickened, about 1-2 minutes. Stir in soy sauce and ½ teaspoon salt, then adjust seasoning as needed.
Slow Cook: Pour the prepared pan sauce into the slow cooker over the beef and vegetables. Cover and cook on High for 4-5 hours or on Low for 7-8 hours, until the vegetables are tender and the meat is easily sliced.
Slice Meat: Remove the roast; identify the grain and slice perpendicular to it into desired thickness. Optionally, cut slices into smaller pieces. Return the meat to the slow cooker to keep warm.
To Serve: Serve the pot roast with vegetables and sauce, garnished with chopped parsley for color and freshness.

Notes

For best flavor, trim excess fat from the chuck roast but leave some marbling for tenderness and richness.
If you don’t have balsamic vinegar, a splash of red wine vinegar can be used as a substitute.
Adjust cooking times based on your slow cooker model; avoid opening the lid frequently to maintain temperature.
Slicing against the grain ensures the meat is tender and easier to chew.
This recipe can be prepared a day ahead; flavors intensify after resting overnight in the fridge.
