Begin by preheating your oven to 325°F (163°C). This allows the oven to reach the perfect temperature for slow-cooking the roast.
In a large Dutch oven, heat the olive oil over medium-high heat. While the oil heats, generously season the beef chuck roast with salt and pepper on all sides. Once the oil is shimmering, carefully sear the roast in the pot, allowing it to brown deeply on each side for about 4-5 minutes. After browning, transfer the roast to a plate and set it aside.
Using the same pot, add the thinly sliced onions along with a pinch of salt. Stirring frequently, cook the onions until they become caramelized and golden brown, which should take approximately 15-20 minutes. When the onions have reached a deep golden color, add the minced garlic and sauté for an additional 1-2 minutes, just until fragrant.
Next, pour in the beef broth and balsamic vinegar, using a wooden spoon to scrape up any delicious browned bits clinging to the bottom of the pot. Stir in the dried thyme and bay leaves to infuse flavor into the broth.
Carefully return the seared roast back into the pot, ensuring that it is mostly submerged in the onion-infused liquid. Cover the pot with a tight-fitting lid and transfer it to your preheated oven.
Allow the pot roast to roast for 3 to 4 hours, checking occasionally to ensure there is still enough liquid. If needed, add additional beef broth to keep the roast moist and flavorful. Roasting is complete when the meat is so tender that it easily pulls apart with a fork.
Once cooked to perfection, remove the roast from the pot and let it rest on a cutting board for 10-15 minutes to allow the juices to redistribute before slicing.
While the roast is resting, place the Dutch oven with the onion broth back on the stovetop and bring it to a gentle simmer. This enhances the flavors before serving.
To serve, slice the pot roast into portions and arrange them on a serving platter. Generously ladle the rich onion broth over the meat, then sprinkle the top with shredded Gruyère cheese. For a delightful finish, place the platter under the broiler for a few minutes until the cheese is melted and bubbly.
Just before serving, garnish with a handful of fresh parsley to add pops of color and freshness.
Notes
For an inviting presentation, serve the pot roast on a rustic wooden cutting board, accompanied by a mound of creamy mashed potatoes.
