Carrots, celeriac, onions, and garlic are peeled and chopped into smaller pieces.
Brown the roast in a pot (that can go in the oven with a lid on).
Take the roast out and sauté the vegetables.
Add red wine and reduce by about 50%.
Put the roast back in and place it on top of the vegetables.
Add beef stock, bay leaves, and thyme, and season with salt and pepper.
Now place everything in the oven at 180 degrees Celsius (356 degrees Fahrenheit) for 1.5 to 2 hours until tender.
Keep an eye on it to make sure it doesn't dry out (add a little extra stock if necessary).
Take the roast out and strain the sauce, thickening it with a bit of cornstarch if needed.
Sauté the pearl onions in a pan with butter for about 5 minutes until slightly colored.
Season with salt and pepper
