White Miso & Matcha Broth with Kohlrabi Matchsticks – 21g Protein | Vegan Lunch

Miso soup rebuilt from the ground up. The base is a quick dashi of dried wakame and fresh ginger – mineral, oceanic, deeply savory in under three minutes. Kohlrabi cut into thin matchsticks for the crunch that snap peas alone can’t provide. Soft tofu cubes warmed through in the broth. Then the heat goes off entirely, and the miso and matcha go in together, whisked into a small ladle of warm broth first so they dissolve completely before hitting the pot. The result is a jade-tinted broth that tastes fermented and grassy and alive in a way that a plain miso broth doesn’t reach.

The off-heat technique is the only rule that matters. Miso contains live cultures that break down above 140°F (60°C) – boil it and you get flavor without the probiotic benefit. The matcha compounds are similarly heat-sensitive and turn bitter when overheated. Both go in after the flame is off, dissolved in warm broth, stirred gently. Thirty seconds of patience that changes the entire character of the bowl.

INGREDIENTS

INSTRUCTIONS:

1. Build the dashi base: Bring the water to a gentle simmer in a small pot. Add the ginger slice and dried wakame. Let them simmer together for 2–3 minutes. The wakame will rehydrate and bloom, releasing mineral depth into the broth. The ginger infuses quietly in the background – not dominant, just present.
2. Add the vegetables: Add the kohlrabi matchsticks and snap peas to the simmering broth. Cook for 2–3 minutes only. You want the kohlrabi to remain slightly firm with a clean snap and the peas to stay bright green. Overcooking both at this stage makes the broth muddy and the vegetables soft – neither is what this soup is.
3. Add the tofu: Dice the soft tofu on a flat surface with a sharp knife using one clean downward motion per cut – sawing breaks it. Aim for 2cm cubes which hold their shape better than smaller pieces. Lower the diced soft tofu gently into the broth using a spoon – do not drop it in or it will break apart. Let it warm through for 30 seconds only. Soft tofu is delicate and needs heat to warm through, not time to cook.
4. Miso and matcha off heat: Turn the heat off completely. Ladle a small amount of warm broth into a cup. Add the white miso and matcha powder and whisk until completely smooth with no lumps – the matcha tends to clump so take an extra 10 seconds here. Pour the dissolved mixture back into the pot and stir gently to combine. Never add miso or matcha directly to boiling liquid – heat above 140°F (60°C) destroys the live cultures in the miso and turns the matcha bitter.
5. Finish with ground hemp seeds: Whisk the ground hemp powder directly into the warm broth off the heat. Ground hemp dissolves into the liquid rather than floating on the surface, creating a smooth, subtly milky mouthfeel that softens the intensity of the fermented miso without any visible seeds or texture. Stir for 20 seconds until fully incorporated.
6. Serve: Pour into a deep bowl. Top with sliced scallion. This soup is best eaten fresh while the broth is still steaming, but it keeps refrigerated for up to 2 days. Reheat gently over low heat without boiling to preserve the miso cultures and matcha compounds.

PRO TIP: Soft tofu gives this soup a silkier, more delicate character – the cubes absorb the miso-matcha broth readily and soften slightly at the edges as they sit, creating a custard-like texture throughout the bowl. If you want something more substantial and protein-forward, firm tofu holds its shape better and gives the soup more body. Both work – choose based on what you want from the bowl.

CHEF’S KISS: Add 3–4 drops of toasted sesame oil drizzled directly onto the surface of the broth just before serving. The oil floats on the jade-green broth in a thin golden slick and releases a deep roasted nuttiness that anchors the delicate matcha-miso flavor without competing with it. Sesame and miso share the same fermented, earthy aromatic family – they amplify each other rather than fight. Impact: +40 calories, +0g protein, but adds a visual finish and aromatic depth that makes the bowl smell like something from a Japanese izakaya the moment it hits the table.
