Heat a skillet on the stovetop. Add a bit of olive oil with your cut up pieces of roast.
Sear on all sides and then transfer beef into slow cooker.
Add diced onions into the same skillet with drippings, add garlic powder (could add diced garlic too if you're a lover) and cook down until caramelized, then add into the crockpot.
Add all other ingredients with the bay leaves on top so they're easier to remove at the end.
Set to low heat for 8 hours or high for 6 hours.
Remove bay leaves. Shred beef with two forks. Serve over noodles.
