Preheat your oven to 275°F — this low temperature will break down the tough connective tissue in the chuck roast without drying it out.
Pat the chuck roast completely dry with paper towels, then season it aggressively with salt and pepper on all sides. Don't be shy here — this big piece of meat needs plenty of seasoning.
Pour the olive oil into a heavy Dutch oven or large oven-safe pot and place over medium-high heat. Let it get hot until it shimmers — you want good searing heat.
Place the onion halves cut-side down in the hot oil and let them caramelize until golden brown, about 3-4 minutes per side. Transfer to a plate and set aside.
Toss the carrot pieces into the same hot pot, stirring occasionally until they develop light golden spots all over. This adds extra flavor depth to your final dish.

Add more oil to the pot if it looks dry, then carefully place the seasoned roast in the center. Sear each side until deeply browned — this creates the flavor foundation for your braising liquid.

With the heat still on high, pour in the red wine (or 1 cup of beef broth if skipping wine) and scrape up all those beautiful browned bits from the bottom using a whisk. This is liquid gold for flavor.
Nestle the seared roast back into the pot, then pour in enough beef broth to come about halfway up the sides of the meat — you're not swimming it, just creating a moist braising environment.
Arrange the browned onions and carrots around the roast, then tuck the rosemary and thyme sprigs into the liquid where they can infuse everything with their earthy aromatics.
Cover tightly with the lid and slide into the oven. Cook for 4-5 hours (4 for a 3-pound roast, 5 for larger cuts) until the meat shreds easily with a fork and the vegetables are perfectly tender.
