Author Notes

Like ramen, traditional versions of pho broth rely on meat for richness, body, and flavor. Vegetarian adaptations are a more delicate affair, and the bright herbs, warm spices, and sweetness of the vegetables must shine in balance. Blackening the ginger and onion is a standard step, lending depth and astringency, and you shouldn’t skip it.

This recipe makes a satisfying stand-alone broth that has the power to nourish and rejuvenate. After an hour of simmering, most any vegetable will have given up all of its flavor to the liquid, and some will even turn bitter if you continue cooking them for too long. I hold off seasoning this broth with salt and sugar until just before serving. This recipe makes enough for two 4-serving batches of pho.

What You'll Need
  • 1 large or 2 small onions, peeled and quartered lengthwise
  • 2 ounces fresh ginger (a 3- to 4-inch piece, depending on thickness)
  • 2 tablespoons peanut oil
  • 2 medium leeks, white and green parts, coarsely chopped into 1-inch pieces
  • 2 large carrots, coarsely chopped into 1-inch pieces
  • 1 medium daikon radish (12 ounces), peeled and coarsely chopped into 1-inch pieces
  • 10 garlic cloves, peeled
  • 1 stalk fresh lemongrass, smashed and coarsely chopped
  • 3 whole star anise
  • 3 whole cloves
  • 2 cinnamon sticks
  • 1/2 teaspoon fennel seeds
  • 5 dried shiitake mushrooms
  • 1 handful fresh cilantro stems
  1. Preheat the broiler. Arrange the onions and ginger on a foil-lined baking sheet. Once the broiler is hot, broil the vegetables close to the heat source until charred all over, flipping them with tongs as needed. Remove the onions if they cook more quickly than the ginger, or vice versa.
  2. Alternatively, char the onions and ginger over the open flame of a gas burner, turning them periodically, until blackened all over. This will need to be done in a few batches.
  3. Heat the oil in a stockpot over medium-high heat. Once hot, add the leeks, carrots, daikon, garlic, lemongrass, star anise, cloves, cinnamon, and fennel seeds. Stir to coat in the oil, then cover and cook for 5 minutes, until fragrant and the colors of the vegetables are vibrant. Coarsely chop the charred ginger, then add it, along with the onions and the mushrooms, to the pot and cover with cold water; you’ll need about 4 quarts. Bring to a boil, then reduce to a gentle simmer and cook for 1 hour, at which point the broth should be strongly flavored. Add the cilantro stems and cook for another 5 minutes.
  4. Strain the broth through a cheesecloth-lined sieve, in batches as necessary, gathering up the ends of the cheesecloth so as to squeeze out as much liquid as possible. Once completely cooled, pack in containers and store in the refrigerator for up to 1 day, or in the freezer for up to 2 months.

I'm a huge fan of this recipe. I add some vegan (because I am) fish sauce (1/4 c.) and 1/4 c. tamari at the end, and it also helps to add some lime juice and sriracha when you're ready to serve. This recipe made vegan pho very possible for me!

I'm making this soon! The recipe is pretty clear, but I have a question -- there's no instruction to peel the ginger before charring. All other instructions are clear regarding prep, so I'm assuming the ginger is charred with peel on. Can you confirm that for me? Can't wait to try this recipe!
