Instructions
Preheat the oven
Preheat your oven to 375°F (190°C).
Pro tip: Ensure the oven is at the correct temperature before placing the roast inside.
Prepare the beef
Rub the beef roast with olive oil, salt, pepper, and thyme. Ensure it's evenly coated.
Pro tip: Let the beef sit at room temperature for 15 minutes to ensure even cooking.
Brown the beef
Heat a large skillet over medium-high heat. Sear the beef on all sides until browned, about 8 minutes.
Pro tip: This step locks in the juices and enhances flavour.
Caramelize the onions
In the same skillet, add the sliced onions and garlic. Cook for 10 minutes until onions are translucent and slightly caramelized.
Pro tip: Stir occasionally to prevent burning.
Combine ingredients
Transfer the onions and garlic to a roasting pan. Place the seared beef on top. Pour the beef broth and balsamic vinegar over the mixture.
Pro tip: Use a roasting rack if available for better heat circulation.
Roast the beef
Place the roasting pan in the oven and roast for 60-70 minutes, or until the internal temperature reaches 135°F (57°C) for medium-rare.
Pro tip: Insert the thermometer into the thickest part of the meat to ensure accuracy.
Rest the beef
Remove the roast from the oven and let it rest for 15 minutes before carving.
Pro tip: Resting allows the juices to redistribute throughout the meat.
Serve and enjoy
Slice the roast beef thinly and serve with the caramelized onions and pan juices.
Pro tip: Pair with your favourite sides for a complete meal.
