Preheat your oven to 325°F (165°C).
Place a large sheet of heavy-duty aluminum foil on a sturdy baking sheet or roasting pan. For extra protection, use two overlapping sheets.
Combine salt, black pepper, garlic powder, thyme, rosemary, and onion powder. Rub the seasoning mixture evenly over all sides of the roast.
For deeper flavor, heat the olive oil in a large oven-safe skillet over medium-high heat.
Place the potatoes, carrots, onion, and garlic around the roast.
Place the seasoned roast in the center of the foil.
Pour the beef broth around the roast rather than directly over the top.
Bring the foil over the roast and vegetables. Fold the edges tightly to create a sealed packet.
Make sure there are no large openings where steam and moisture can escape.
Bake for approximately 2½–3 hours, depending on the size and thickness of the roast.
Carefully open the foil because hot steam will escape.
For a shreddable pot roast, cooking until the connective tissue has broken down is more important than simply reaching the minimum safe temperature.
Carefully transfer the roast to a cutting board and loosely cover it.
Arrange the beef and vegetables on a serving platter.
Garnish with fresh parsley and serve hot.
