In a Dutch oven, heat canola oil over medium-high heat. Brown the beef on all sides for about 5-7 minutes, then drain any excess oil.
Add apple cider, beef broth, cider vinegar, salt, dried thyme, and pepper to the Dutch oven. Bring to a boil, then reduce heat, cover, and simmer for 1-1/4 hours. Stir occasionally to prevent sticking.
After 1-1/4 hours, add potatoes, carrots, celery, and onions to the pot. Bring back to a boil, then cover and simmer for an additional 30-35 minutes, or until the beef and vegetables are tender. Ensure to check the vegetables for doneness.
In a small bowl, mix the flour and water until smooth. Stir this mixture into the stew. Bring to a boil and cook for 2 minutes, or until the stew thickens. For a thicker stew, feel free to adjust the flour and water mixture to your preference.
Optionally, serve the stew with fresh thyme sprigs to add a touch of freshness and color.
Notes
For a thicker stew, you can adjust the amount of flour and water mixture to your preference. No alcoholic drinks allowed, please substitute with a non-alcoholic option.
