1Pat the chuck roast dry and season generously with coarse kosher salt and black pepper. Refrigerate uncovered overnight.
2Cut heat to medium-high, add oil to the Dutch oven and let it shimmer.
3In a separate bowl, mix together 1/2 cup all-purpose flour with salt, pepper, onion powder, and garlic powder.
4Cover the chuck roast in the seasoned flour.
5Place the floured chuck roast in the Dutch oven and cook for 4-5 minutes on each side to create a nice brown crust.
6Rough chop 1 large onion, 3 large carrots, and 3 ribs of celery.
7Add the chopped vegetables to the Dutch oven and cook for 5 minutes.
8Add 10 cloves of roughly chopped garlic and a 4.5-ounce tube of tomato paste. Stir and fry for 5 more minutes until tomato paste caramelizes.
9Add 1 cup of red wine (or beef stock) and stir.
10Reduce heat to low. Add 1 spoonful of Better Than Bouillon, a few dashes of Worcestershire sauce, more garlic powder, and more black pepper.
11Add 3 cups of beef stock and bring to a simmer.
12Place the roast back into the Dutch oven, ensuring it's mostly submerged in the gravy.
13Add 1 sprig of fresh thyme and 2 bay leaves.
14Cover the Dutch oven with tin foil (to prevent steam from escaping) and place in a 275°F preheated oven for at least 3.5 hours (or up to 4 hours) or an hour per pound of meat.
15Remove the thyme and bay leaves. Shred the roast using a spoon.
16In a separate bowl, combine 1 tablespoon of room-temperature butter and 2 tablespoons of all-purpose flour to make a paste.
17Add the butter and flour paste to the gravy and stir over low heat until the gravy thickens.
