• 1 pound / 450g (15.9 oz) fresh green beans, cleaned and trimmed

• 3 tablespoons / 45ml (1.5 fl oz) malt vinegar, divided

Instructions
1. Directions
2. Preheat your oven to 400°F / 200°C.
3. In a large mixing bowl, combine the radishes, green beans, avocado oil, 2 tablespoons (30 ml / 1 fl oz) of the malt vinegar, 1 teaspoon of the sea salt, and the black pepper. Toss well until everything is evenly coated.
4. Spread the vegetables in a single, even layer on a large, rimmed baking sheet.

Pro Tips
• For the best browning and flavor, ensure the vegetables are in a single layer on the baking sheet. Use two sheets if necessary to avoid overcrowding the pan.
• The final drizzle of vinegar is key for a bright, tangy finish. Don’t skip this step, as some of the vinegar’s flavor cooks off in the oven.
• For an even easier version, use a pre-made malt salt. Simply toss the vegetables with oil and season to your liking before and after roasting.
• These vegetables are a fantastic side for roasted chicken, grilled steak, or a flaky white fish like cod.
FAQ
Q: What do roasted radishes taste like
A: Roasting completely transforms radishes. Their sharp, peppery bite mellows out, and they become tender and slightly sweet, taking on a savory flavor from the roasting process.
Q: Can I use a different vinegar instead of malt vinegar
A: Yes, while malt vinegar gives a classic ‘salt and vinegar’ flavor, you can substitute it. Apple cider vinegar or white wine vinegar would also work well, providing a similar tangy finish.
Q: Why are my vegetables not getting brown and crispy
A: The most common reason is overcrowding the baking sheet. For the best browning and flavor, ensure the vegetables are in a single, even layer. If your pan is too full, the vegetables will steam instead of roast. Use two baking sheets if necessary.
Q: Can I use other vegetables in this recipe
A: Absolutely! This salt and vinegar method is fantastic on other root vegetables like small potatoes or carrots, and also works well with Brussels sprouts or broccoli florets. You may need to adjust the roasting time accordingly.
Pro Tips
- Spread the vegetables in a single layer and use two baking sheets if needed — this is what gets them browned and roasted rather than steamed.
- Toss the vegetables halfway through the 25-minute roast so every cut face gets time against the hot pan and browns evenly.
- The final drizzle of vinegar is essential — some of the vinegar's flavor cooks off in the oven, so the raw finish is what delivers the bright tang.
- For an even easier version, use a pre-made malt salt: toss the vegetables with oil and season before and after roasting.
- Halve small radishes and quarter large ones so the pieces match the green beans and everything roasts to tenderness together.
Frequently Asked Questions
Do roasted radishes still taste peppery?
Roasting mellows their peppery bite considerably, leaving them tender and mild — closer to a tiny roasted potato than the raw radish you know.
Can I make this ahead of time?
It is best fresh, when the vinegar finish is brightest. Leftovers keep 3 days in the fridge; rewarm in a hot oven and add a fresh splash of vinegar.
Is this side dish keto-friendly?
Yes. Each of the 4 servings has 9.1 g total carbs and 3.9 g fiber — 5.3 g net carbs — with 4.9 g fat and 2.2 g protein.
What does it pair well with?
The recipe suggests roasted chicken, grilled steak, or a flaky white fish like cod — the tangy salt-and-vinegar profile cuts through rich mains nicely.
