Preheat oven to 275℉. (or 135℃.)

Heat vegetable oil in a Dutch oven (oven-safe) over Medium-High heat. When oil is shimmering, add onion wedges. Cook 2-3 minutes, stirring occasionally until slightly browned and translucent. Remove/Transfer onions to a plate. Add carrots to the hot pot; cook 2-3 minutes on Medium-High until slightly browned. Remove/Transfer carrots to the plate, as well.

Generously season roast with salt and pepper on all sides. Add more oil to the pot (if necessary); heat on Medium-High. When oil is hot, add roast. Cook meat for 1-2 minutes without moving it, then turn to the other side; repeat to ensure all sides are browned (but not cooked through). When done, remove/ transfer roast out of the pot to a plate.

Add 1 cup beef broth and minced garlic to the pot; cook on Medium-High for 1-2 minutes. Use a spoon to scrape the browned bits off the bottom as it cooks. Remove pot from the heat.

Place roast back into the pot; add remaining 2 cups beef broth. Broth should come about ½ way up the sides of the roast. Add carrots and onions. Place sprigs of fresh rosemary and fresh thyme on top. Put a lid on the pot and bake roast at 275° F. for 3 hours (low and slow!). NOTE: If using a larger roast (4-5 pounds), you will need to let it bake for about 4 hours.

When finished baking, carefully transfer roast to a serving platter. Be careful, the meat is usually fall-apart tender! Discard thyme and rosemary. Arrange carrots and onions on platter; spoon a bit of broth over the top, if desired.  Slice pot roast into portions, transfer to plates; add onions and carrots. Serve, and enjoy!
