Pat the meat dry with paper towels if needed. Coat both sides with oil, then sprinkle the salt, onion powder, garlic powder, and pepper evenly across both sides. Heat a 12 inch skillet (I use cast iron) on high heat. Once hot, sear each side for 4-5 minutes, until nicely golden brown, then place it in a 6qt slow cooker.
3-4 lb chuck roast, 2 tablespoon olive oil, 1.5 teaspoon kosher salt, 1.5 teaspoon onion powder, 1.5 teaspoon garlic powder, 1 teaspoon pepper
Pour the broth in the hot skillet and simmer for 60 seconds, scraping up the brown bits from the bottom of the pan. Then pour the liquids on top of the meat in the slow cooker. Cover with the lid and cook on low for 8-10 hours or on high for 4.5-5 (low always seems to yield more tender meat, but it can work both ways).
1 cup beef broth
Once the meat is tender, whisk together the sauce ingredients in a microwave safe bowl (I like to use a glass measuring cup that is deep to avoid overflow). Microwave on high heat in 30-60 second increments, stirring well between each one, until it is thickened, 3-4 minutes total.
1 tablespoon ginger, 2 teaspoon garlic, ½ cup honey, ⅓ cup soy sauce, ¼ cup gochujang, 2 tablespoon rice vinegar, 1 tablespoon cornstarch
Carefully remove the meat from the slow cooker and place onto a cutting board. Discard the cooking juices. Gently separate the meat from the fatty sections (discarding the fat) and shred the meat into large-ish chunks (it will fall apart into smaller chunks in the next step).
Place the meat back into the empty slow cooker and pour the sauce on top. Stir gently until the sauce is evenly coating the meat, then serve over rice.
