Preheat oven to 325°F (163°C).
Season the roast: Pat the roast dry with paper towels. Rub with salt, pepper, garlic powder.
Sear the meat:
Heat oil in a large Dutch oven or oven-safe pot over medium-high heat.
Sear roast on all sides (about 3–4 minutes per side) until browned.
Remove and set aside.
Sauté aromatics:
In the same pot, add onion and garlic. Sauté 2–3 minutes.
Stir in tomato paste (if using), then add the broth/wine to deglaze the pan, scraping up brown bits.
Return roast to pot:
Place the chuck roast back into the pot.
Cover tightly with a lid.
Place in the oven and bake for 2 hours.
Add vegetables:
After 2 hours, carefully remove from oven.
Add potatoes and carrots around the roast.
Re-cover and return to oven for another 1 to 1½ hours, until the meat is fork-tender and the vegetables are soft.
Rest & serve:
Remove roast and veggies from the pot.
Let meat rest 10 minutes before slicing or shredding.
Optionally, reduce the pan liquid on the stove to make a quick gravy.
