Start by taking your chuck roast and trimming off any large, hard pieces of fat that won't render down, as this keeps the final dish from being too greasy. Once trimmed, season the meat generously on all sides with salt, pepper, and your curry powder to ensure flavor penetrates deep into the beef. This initial seasoning step is crucial for building a robust foundation of flavor before the slow cooking process even begins.
Place your seasoned beef roast carefully into the bottom of the slow cooker insert, making sure it sits flat so it can cook evenly. Pour the can of coconut milk over the meat, then toss in your minced garlic and diced yellow onions around the sides of the beef. This creates a braising environment where the meat will slowly become tender while infusing the liquid with savory beef juices.
Cover the pot with the lid and set your slow cooker to the low heat setting for exactly 8 hours to achieve maximum tenderness. Avoid lifting the lid during this time, as releasing the steam drops the temperature and can significantly interfere with the cooking process. You want the connective tissues in the chuck roast to completely break down so the meat falls apart with zero effort.
Once the cooking time is up, the beef should be incredibly tender; use two forks to gently pull the meat apart directly in the pot. Stir the shredded beef around in the liquid so that every single strand gets coated in the rich, curry-spiced coconut broth. This step ensures that every bite is juicy and flavorful, integrating the meat fully into the sauce.
While your beef is resting in the sauce, boil a separate pot of water and cook your ramen noodles according to the package instructions. It is usually better to slightly undercook them by a minute, draining them immediately so they retain a nice, chewy texture. Cooking them separately prevents them from getting mushy or soaking up all your delicious curry broth in the slow cooker.
Add the cooked, drained noodles into the slow cooker or place portions of noodles into individual serving bowls. Ladle the hot beef and plenty of the rich curry broth directly over the noodles to warm them through. Finish the dish by sprinkling generous amounts of fresh cilantro on top for a vibrant pop of color and flavor.
