In a large pot, heat 1 tablespoon of the oil over medium-high heat. Add half the steak and cook, stirring frequently, until well browned, about 2 minutes. Remove the steak with a slotted spoon. Repeat with another tablespoon of oil and the remaining steak, and remove the steak similarly once it is cooked.
Reduce the heat to medium-low and add the remaining tablespoon of oil to the pot. Add the onion and cook, stirring occasionally for about 5 minutes. Add the carrots, celery and potatoes, and continue sauteing for another 3 minutes.
Add the next seven ingredients (beef stock through seasoned salt) and the cooked steak to the pot, and stir to combine. Bring to a boil, scraping the bottom of the pot with a spoon to dislodge any brown bits from cooking the steak. Reduce the heat, cover pot, and simmer for 1-2 hours (the more the merrier – especially for tenderizing the meat and seasoning the broth). Just before serving, season with salt and lots of freshly-ground black pepper. Then serve.
