Steps
1. Preheat the oven to 325°F (163°C).
2. Season the short ribs with salt and pepper.
3. Heat the olive oil in a large oven-safe pot over medium-high heat. Add the short ribs and sear on all sides until browned, about 5 minutes.
4. Remove the short ribs from the pot and set aside.
5. In the same pot, add the diced onion, carrots, and garlic. Sauté until the vegetables are softened, about 5 minutes.
6. Stir in the tomato paste and cook for another minute.
7. Deglaze the pot with the red wine, scraping up any browned bits from the bottom.
8. Return the short ribs to the pot and add enough beef broth to cover them.
9. Bring the mixture to a simmer, then cover the pot and transfer it to the preheated oven.
10. Braise the short ribs for 2.5 to 3 hours, or until the meat is tender and easily pulls apart.
11. Remove the pot from the oven and skim off any excess fat from the sauce.
12. Serve the short ribs with the red wine sauce and enjoy!
