Instructions
Preheat oven to 350F.
Trim the roast of any loose or excess fat. Season all sides with salt and pepper.
Heat oil in a skillet over medium high heat. Place the beef roast in the skillet and sear for 60-90 seconds per side.
Once seared, place in the middle of a large roasting pan. Surround the beef with all the chopped up veggies.
Place the sprigs of thyme on the beef roast, and pour in the beef broth. If desired, sprinkle a little extra salt and pepper all over the vegetables.
Cover the roasting pan with the lid and place in the oven. Cook for 3-4 hours.
Using a baster, draw out the broth from the roasting pan and fill into a saucepan. Bring the broth to a boil over medium heat. Make a slurry by whisking together the corn starch and water. Slowly pour the slurry into the broth, whisking constantly. Lower the heat to a simmer and continue to stir until the gravy thickens.
Let the roast rest for 5 minutes before carving. Slice into thin strips. Serve on a plate with some of the roasted veggies and ladle a little gravy on top.
