Key Ingredients and Tips
- Radishes: I love their sharp, peppery bite when raw, but cooking mellows that punch into a sweet, smoky note—try slicing thin for even heat exposure.
- Garlic: Its pungent aroma wakes up the dish; I crush it to release oils, but if you prefer a milder flavor, toss it in later to avoid burning.
- Soy sauce: Adds umami and saltiness; I prefer a darker, richer variety, but feel free to cut back if you’re watching sodium or want a lighter taste.
- Sesame oil: Just a splash brings a toasty, nutty aroma; I recommend adding it at the end to keep that vibrant scent intact.
- Vegetable oil: I use a neutral oil for quick heat, but if you want extra flavor, a touch of peanut oil works beautifully—just watch the smoke point.
- Optional chili flakes: For a kick of heat, I sprinkle these in during stir-frying; start small, as their heat can surprise you if you’re sensitive.
- Spring onions: I toss them in last for a fresh, mild onion hit; if you want more bite, add them earlier to soften slightly, but keep their crunch.

Ingredient Swap Ideas
- Dairy-Free: Swap soy sauce for coconut aminos—less salty, sweeter, but still adds umami punch.
- Vegan: Use tamari or coconut aminos instead of soy sauce for a gluten-free, plant-based option.
- Low-Sodium: Choose a reduced-sodium soy sauce; the stir fry will still have plenty of flavor, just milder.
- Sesame Oil: Substitute toasted walnut or avocado oil for a different nutty aroma, but keep in mind the flavor will shift.
- Radishes: Turn to sliced kohlrabi or green beans for a different crunch and mild flavor, if radishes aren’t available.
- Garlic: Shallots or leeks can replace garlic for a milder, sweeter onion flavor; add later to avoid burning.
- Chili Flakes: Use fresh sliced chili or hot sauce for a fresher, more vibrant heat, adjusting amount to taste.

- Keep soy sauce and chili flakes in the fridge for freshness; they won’t lose much flavor and will be ready to pour in for that quick flavor boost.
- Refrigerated radishes will retain their crunch for about 1-2 days. For best texture, add to stir-fry immediately before cooking.
- Reheat leftovers gently in a hot skillet or wok, stirring constantly. The radishes will soften slightly, but their bright flavor and aroma will still shine through. Expect about 3-4 minutes until warmed through.
- For longer storage, radish slices can be frozen for up to a month, but expect some loss of crunch. Thaw in the fridge and reheat quickly for best texture.
