Instant Pot Taiwanese Beef Noodle Soup

Optional - Parboil Beef Meat: Bring 4 quarts of water to a boil. Boil the beef for 5 minutes to clean and remove excess fat.

Press “Saute” button to “Sauté More” to heat up Instant Pot. When the spices release their fragrance (~2.5 mins), remove and set aside the toasted spices.Brown Beef in Instant Pot: Wait until the Instant Pot says "HOT". Pat dry the beef shanks and chuck roast steak, then lightly season one side of beef with salt. Drizzle 1 tbsp (15ml) vegetable oil in the inner pot, then ensure to coat the oil over the whole bottom of the pot. Carefully place the seasoned side of beef in Instant Pot. Lightly season the other side of beef with salt. Brown one side of the beef for 5 minutes before flipping over, then brown the other side for another 5 minutes. Set aside the browned beef.Saute Onions and Tomatoes: Add 1 tbsp (15ml) vegetable oil in Instant Pot.
