Heat oil in a large pot over medium heat. Add beef and cook until browned on all sides, about 5 minutes.
Remove meat from the pot and set aside in a bowl. Add garlic and onion to the pot. Cook until the onions are soft, about 4 to 6 minutes. Stir often to prevent the garlic from burning.
Add meat back to the pot and sprinkle flour over meat and veggies. Stir until coated and cook for 1 minute.
Pour in the pasta sauce and beef broth, and stir to combine. Add your potatoes and carrots, then give one more stir.
Cover and simmer over medium heat for about 1 hour. Stirring every 20 minutes.
Uncover and season with salt and pepper to taste. Serve warm.
Notes
If you can't find pre-cut stew meat, you can take a chuck or bottom round roast and use about half of it. Then cut up the other half into stew meat and freeze it for later.
