Instructions

Season the Roast: Pat the chuck roast dry with paper towels and generously season all sides with salt and black pepper to enhance flavor and help create a beautiful crust.
Sear the Roast: Heat olive oil in a Dutch oven over medium-high heat. Once hot, sear the roast on all sides until it achieves a deep, golden brown crust. Remove the roast from the pot and set aside to retain the flavorful fond.
Caramelize Onions: Add sliced onions to the pot along with a pinch of salt. Cook over medium-low heat, stirring frequently, for about 25–30 minutes until the onions are deeply caramelized and sweet.
Add Garlic: Stir in the minced garlic and cook for one minute until it becomes fragrant but not burned, enhancing the aromatic profile of the dish.
Deglaze the Pot: Pour in the balsamic vinegar and Worcestershire sauce, stirring and scraping the bottom of the pot to lift all the caramelized bits. Let the mixture simmer for 2 minutes to reduce slightly.
Combine Ingredients: Return the seared roast to the pot. Pour in the beef broth and add the fresh thyme sprigs, which will infuse the meat with herbal notes. Bring the mixture to a gentle simmer.
Oven Braise: Cover the Dutch oven with its lid and transfer it to a preheated oven set at 300°F (150°C). Cook the roast for 3 to 3.5 hours, or until the meat is fork-tender and easily pulls apart.
Rest and Serve: Remove the pot roast from the oven and allow it to rest, covered, for 10 to 15 minutes. Slice the meat and serve it warm with the rich onion gravy from the pot drizzled on top.

Notes

Using a well-marbled chuck roast ensures tender, flavorful meat after slow cooking.
Caramelizing the onions slowly over low heat develops their natural sweetness and depth of flavor.
Allowing the meat to rest before slicing helps retain its juices, keeping the roast moist.
If desired, thicken the onion gravy by simmering it on the stovetop with a slurry of cornstarch and water for a few minutes.
This dish pairs wonderfully with mashed potatoes, roasted vegetables, or crusty bread to soak up the delicious sauce.
