To a large heavy-bottomed pot, add the olive oil over medium heat.
Once olive oil is warmed through, add the carrots, celery and onion. Add the thyme, rosemary and bay leaves, along with salt and pepper.
Let vegetables cook down, about 5 minutes.
Add the beef and let it brown, about 10 minutes. Note that the beef will not caramelize, since it was added after the vegetables.
Add the wine, and let the alcohol evaporate off, a few minutes.
Add the passata and water, along with a bit more salt and pepper and let it come to a boil. Turn the heat down to low, put a lid on the pot, and let stew cook, stirring occasionally.
Stew should cook for about 2.5-3 hours.
If adding potatoes, add them when there is about 1 hour 15 minutes left in total cook time. Add more water if necessary (about ½ cup to 1 cup water)
Beef and potatoes should be tender at the end of cook time. Serve and enjoy!
