Instructions:
Prep Ingredients:
Clean oxtail with coarse salt and lime juice, rinse, and pat dry.
Slice ginger and peel onions. If using pre-cooked beef meatballs, halve them.
Sear and Sauté:
Sear oxtail in the Instant Pot on the sauté mode until golden brown. Remove and set aside.
In the same pot, toast onions and ginger in the rendered beef fat until fragrant.
Pressure Cook:
Return oxtail to the pot, add water to cover, and pressure cook on high for 30 minutes.
Prepare Garnishes and Noodles:
Slice green onions, yellow onions, jalapenos, and limes. Set aside.
Soak rice noodles in water to remove excess starch.
Season Broth:
Quick release pressure. Skim off excess fat from the broth.
Season broth with rock sugar, salt, fish sauce, and MSG. Add phở spice bag or powdered spices. Simmer for 15 minutes.
Strain and Finish:
Strain the broth, removing all solids. Return the meat to the pot, and add water to make a total of 4 quarts of broth. Add beef balls and bottom stems of green onions. Boil briefly.
Cook Noodles and Serve:
Boil noodles briefly, then transfer to bowls. Top with oxtail, meatballs, and garnishes. Ladle hot broth over the top. Enjoy with lime wedges and optional sauces.
FAQs:
Can I use other beef cuts? Yes, beef shanks or short ribs work well if oxtail is unavailable.
No Instant Pot? Use a stovetop method for a traditional approach.
MSG: Optional but enhances flavor; reduce or omit if preferred.
Storing leftovers: Keep components separate. Refrigerate for up to 3 days. Reheat broth and blanch noodles before serving.
