Simple Roasted Radishes with Rosemary
Crisp, peppery radishes transform into mellow, slightly sweet bites when roasted. Tossed with fresh rosemary and olive oil, the high heat caramelizes their edges while keeping the centers tender. A surprisingly elegant side dish that comes together with just a handful of ingredients and 30 minutes in the oven.

Trim and halve the radishes.
Wash the radishes well. Trim off the leafy tops and root tips. Cut larger radishes in half and leave very small ones whole. Aim for roughly equal size so they roast evenly.
TIPKeep radish pieces similar in size — about 1 to 1.5 inches — so they finish cooking at the same time. - mix
Toss radishes with oil, rosemary, garlic, salt, and pepper.
Place the prepared radishes on the baking sheet. Drizzle with olive oil, then scatter the chopped rosemary and minced garlic over the top. Sprinkle with salt and black pepper. Toss everything together with your hands until the radishes are evenly coated, then spread them into a single layer with cut sides facing down.
