Can I make oxtail pho without a pressure cooker?
Yes. Simmer oxtails and bones in a pot for 3–4 hours instead, skimming impurities frequently. The pressure cooker cuts cooking time to about 1 hour while achieving similar tenderness and broth clarity.
Why do you toast the spices in oxtail pho?
Toasting star anise, cinnamon, cardamom, cloves, and fennel releases their oils and deepens their flavor, creating a more fragrant and complex broth than raw spices.
How do I get a crystal-clear broth?
Use a pressure cooker to reduce cooking time and foam buildup. Skim any scum from the surface early in cooking. Avoid stirring vigorously, which clouds the broth. Strain through fine mesh or cheesecloth at the end.
Can I substitute oxtail with another cut of beef?
Yes. Beef chuck, brisket, or short ribs work well. Oxtail is preferred for its collagen content and rich marrow flavor, but these cuts still produce flavorful pho with slightly less body in the broth.
How far ahead can I make the broth?
Make the broth up to 3 days ahead and refrigerate; skim fat from the surface once cooled. Reheat gently before serving with noodles and garnishes.
