Ingredients Needed
To create a rich vegetarian pho broth, you’ll need the following:
- Vegetable Broth: The base of your pho. You can use store-bought or homemade vegetable broth. If you’re making your own, aim for a rich, flavorful version that will carry the soup’s flavors.
- Onions: One medium onion, halved and charred. This step adds a smoky sweetness to the broth.
- Ginger: A thumb-sized piece of fresh ginger, lightly smashed. Ginger provides a warming, spicy depth to the broth.
- Star Anise: 2-3 pods of star anise. This spice is essential for giving pho its distinctive, sweet, and slightly licorice-like aroma.
- Cinnamon Stick: 1 stick of cinnamon. It imparts a subtle sweetness and warmth.
- Cloves: 3-4 whole cloves. These add a spicy, aromatic note to the broth.
- Cardamom Pods: 2-3 whole pods. Optional, but they bring a unique floral spice to the mix.
- Soy Sauce: 2-3 tablespoons for umami and depth.
- Mushrooms: A handful of shiitake or other earthy mushrooms. Mushrooms are key to adding a rich, umami flavor to the vegetarian broth.
- Bok Choy or Napa Cabbage: A few leaves for a light crunch and mild sweetness.
- Carrots: 2 medium carrots, sliced. Adds natural sweetness and color.
- Daikon Radish: 1 medium radish, sliced. Optional, but it adds an additional layer of mild, peppery flavor.
- Fresh Herbs: Cilantro, basil, and mint. These are for garnishing and adding freshness.
- Lime: Fresh lime wedges for serving, adding that zesty citrusy touch.
- Rice Noodles: Thin, flat rice noodles, traditionally used in pho. These noodles soak up the broth and add a delightful texture.
- Chili Peppers: Fresh or dried, to garnish if you want some heat.
Cooking Instructions
Making vegetarian pho broth is a process of building flavors over time. Here’s a step-by-step guide:
-
Prepare The Vegetables
- Char the onions and ginger. Place them on an open flame or under a broiler for 5-10 minutes, turning them until they’re slightly blackened. This adds a smoky flavor to the broth.
- Lightly smash the ginger with the flat side of a knife to release more flavor.
-
Toast The Spices
- In a dry pot over medium heat, toast the star anise, cinnamon stick, cloves, and cardamom pods for about 1-2 minutes. This will release their essential oils and intensify their aromas.
-
Make The Broth
- Add the vegetable broth, charred onions, ginger, and toasted spices into a large pot. Bring it to a simmer and let it cook gently for 30-45 minutes. The longer it simmers, the richer the flavors will become.
- Add the soy sauce, mushrooms, carrots, and daikon (if using) about 20 minutes into the simmering process. This will allow the vegetables to soften and release their flavors without overcooking.
-
Strain And Final Touches
- After simmering, strain the broth to remove all the solids. Return the clear broth to the pot.
- Taste the broth and adjust the seasoning by adding more soy sauce if needed for saltiness, or a little sugar for balance.
-
Prepare The Noodles
- Cook your rice noodles according to the package instructions. Drain them and divide them into bowls.
-
Assemble The Pho
- Pour the hot broth over the cooked noodles. Top with fresh herbs like cilantro, basil, and mint. Add lime wedges and chili peppers on the side for extra freshness and heat.
Ingredient Science Spotlight
- Star Anise: The star-shaped spice isn’t just visually stunning; it’s packed with aniseed flavor, contributing to pho’s signature scent. Its sweet, licorice-like taste combines with other spices to create a warm, aromatic foundation.
- Mushrooms: Shiitake mushrooms (or any other type you prefer) are rich in glutamates, which naturally enhance the savory umami flavor of the broth. This is especially important in vegetarian pho, where the broth lacks the depth of meat.
- Soy Sauce: This fermented soy product is a powerhouse of umami. It’s the savory backbone of the vegetarian pho broth, making up for the absence of animal proteins while giving the soup a rich, deep flavor.
- Ginger: Beyond its sharp heat, ginger also carries a hint of citrus, making it a balancing agent in pho. It works beautifully with the other spices, cutting through their richness while adding warmth.
Expert Tips
- Layered Broth: If you want a super-deep, flavorful broth, consider simmering your broth for longer, even up to 2 hours. Just be sure to add water periodically if it reduces too much.
- Make it Ahead: Pho broth often tastes even better the next day. If you have time, make it ahead and let it sit overnight in the fridge to allow the flavors to meld.
- Customize with Toppings: Feel free to add more than just fresh herbs. Sliced radishes, bean sprouts, or crispy tofu make great toppings for extra texture and flavor.
- Herbal Boost: If you’re a fan of herbal tones, add a piece of lemongrass or a few kaffir lime leaves to the broth for an extra burst of freshness.
Recipe Variations
- Spicy Pho: Add more chili peppers or a dash of sriracha to the broth for a spicy kick. You can also blend in some fresh chili paste for a rich, flavorful heat.
- Mushroom Pho: Go all-in on the mushrooms by adding a variety like cremini, enoki, or oyster mushrooms. Their different textures will elevate the depth of the broth.
- No Soy Sauce: For a gluten-free version, substitute soy sauce with tamari or coconut aminos. These alternatives still give you that much-needed umami without any wheat.
- Noodle-Free: For a lower-carb version, replace rice noodles with zucchini noodles or shirataki noodles. They’ll soak up the broth beautifully and keep the soup light.
Final Words
Vegetarian pho may take a little extra patience, but the rewards are so worth it. With its deep, fragrant broth and fresh toppings, it’s a dish that brings comfort and joy with every spoonful. Whether you’re serving it on a chilly day or as a nourishing light meal, this vegetarian pho recipe is a sure winner.
