Remove roast from fridge 30 minutes prior to cooking.
Preheat the oven to 400F. Heat olive oil in a large Dutch oven set over medium-high heat. Season the roast with salt and pepper, then sear it on all sides until nicely browned. Remove from the heat.
Tuck the onion, potatoes, and carrots under and around the chuck roast.
In a bowl, whisk together the soups, water, and soup mix until well combined, then pour over the roast.
Place the lid on top of the Dutch oven and place in the oven. Cook for 20 minutes, reduce the oven to 325F, and continue roasting for another 4-5 hours, until the beef pulls apart easily with a fork.
Remove the Dutch Oven and allow roast to rest for 15 minutes with the lid on.
Transfer the roast to a serving plate, garnish with herbs as desired, and serve with the vegetables and gravy.
Notes
Rest for Success - you want to rest your Pot roast before and after cooking for peak tenderness. Resting at room temperature before cooking, raises the internal temperature of the roast allowing it to cook more evenly. Resting for 15 minutes after cooking, allows the natural juices to redistribute resulting in a tender, juicy roast.Dry Brine - If you have the time, generously season your roast with salt and pepper the night before and place back in the fridge. You are essentially dry brining the meat, which will enhance its flavor and tenderness.
