Follow these simple steps to create the Tender Balsamic Cranberry Beef Roast:

1. Preheat Oven: Preheat your oven to 300°F (150°C).
2. Prepare the Roast: Pat the beef roast dry with paper towels. Season generously with salt and black pepper.
3. Sear the Beef: In a large oven-safe pot, heat olive oil over medium-high heat. Sear the roast on all sides until browned, approximately 3-4 minutes per side. Remove the roast and set aside.
4. Sauté Vegetables: In the same pot, add chopped onion and minced garlic. Sauté until the onion is translucent, about 3-5 minutes.
5. Add Liquids: Pour in the balsamic vinegar, beef broth, and cranberry sauce. Stir to combine, ensuring the sauce is well mixed.
6. Return the Roast: Place the seared beef roast back into the pot, spooning some of the sauce over the top.
7. Add Herbs: Sprinkle dried thyme and rosemary over the roast for added flavor.
8. Cover and Cook: Cover the pot with a lid and place it in the preheated oven. Cook for 1 hour and 30 minutes, or until the meat is fork-tender.
9. Check Doneness: Use a meat thermometer to ensure the internal temperature reaches at least 145°F (63°C) for medium-rare.
10. Rest the Roast: Remove the pot from the oven and let the roast rest for 10-15 minutes before slicing. This allows the juices to redistribute for maximum tenderness.
