- Mild and sweet
- Slightly nutty

What to Serve with Roasted Radishes
Ideal pairings:
- Grilled or roasted meats (chicken, steak, pork chops)
- Roast dinners as a potato substitute
- Eggs and brunch platters
- Grain bowls with quinoa, lentils, or couscous
- Topped on soups for added texture
They also work beautifully as part of a roasted veg medley with carrots, parsnips, and sprouts.
Can You Roast Radish Greens?
While radish leaves are better sautéed or used in pesto, small baby greens can be roasted at the same time for a crispy chip-like texture.
Tip: Toss them in olive oil, salt, and roast for just 5–7 minutes separately to avoid burning.
Storage and Leftovers
- Store leftovers in the fridge for up to 4 days
- Reheat in the oven or air fryer to revive crispiness
- Avoid microwaving, which softens texture
- Use cold in salads, wraps, or lunch bowls
You can also blend them into mashed potatoes or soups for a peppery twist.

- Sow from March to September
