A comforting bowl of Taiwanese-inspired beef noodle soup featuring tender beef shank, silky wheat noodles, and a fragrant charred aromatic broth that mimics an all-day simmer.
Bring a pot of water to a full, rolling boil. Add the beef shank and boil for exactly 1 minute to release impurities.
Drain the beef in a colander and rinse thoroughly with fresh water to remove any gray foam and residue.
Char, sauté, and build the aromatic base
Char the halved onion and ginger over an open flame or under a broiler until the skins are well blackened. Peel away the heavy burnt outer layer to reveal smoky, sweet flesh.
Set the Instant Pot to Sauté, add oil, then sauté the ginger, garlic, scallions, and charred onion until caramelized and fragrant.
Add the tomato and dried chilies, cooking until the tomato softens and creates a jammy, aromatic base.
Coat the beef and pressure cook
Add the blanched beef to the pot. Stir in the tomato paste, douban jiang, sugar, soy sauce, and Shaoxing wine until the meat is stained red-brown and fragrant.
Pour in 8 cups of water and add the spice sachet. Pressure cook on the Meat/Stew setting for 100 minutes, or simmer on the stovetop for 3 to 4 hours until the beef is fork-tender.
Noodles, bok choy, and the final bowl
Release the pressure carefully. Cook fresh wheat noodles in a separate pot. In the final minute of noodle cooking, blanch the bok choy until bright green.
Place noodles and bok choy into bowls, ladle over the rich broth and beef chunks, and garnish with cilantro, scallions, and pickled mustard greens.
Notes
Beef Selection: Beef shank is essential for its high collagen content. As it braises, the connective tissue melts into gelatin, providing a silky, lip-smacking texture that lean cuts cannot provide.Noodle Preparation: Always cook noodles in a separate pot of water. Boiling them directly in the soup releases starches that will make your clear broth cloudy and thick.The Charring Secret: Don't skip charring the onion and ginger. This Maillard reaction creates smoky sweetness and complexity that usually requires 24 hours of simmering.Storage Strategy: Store the broth, meat, and noodles in separate containers. If kept together, the noodles will act like a sponge and become mushy by the next day.Nutrition information is estimated based on common ingredients and serving sizes and may vary.
