Garlic Parmesan Roasted Radishes
Ingredients
Method
- Preheat oven to 425°F. Line a baking sheet with parchment paper. Wash, trim, and thoroughly dry the radishes. Cut into uniform halves or quarters, depending on size.
- Toss the radishes with olive oil, garlic powder, salt, and black pepper. Arrange in a single layer, cut-side down where possible.
- Roast for approximately 20 minutes, then flip. Continue roasting for another 5–10 minutes, checking for tender centers and golden-brown edges. Adjust as needed for radish size and browning.
- Sprinkle the finely shredded Parmesan over the radishes. Return to the oven for approximately 3–5 minutes, until the cheese is lightly golden.
- Taste and add more salt if desired. Serve warm.

Let us know how it was!Frequently Asked Questions
How can I get my roasted radishes more browned?
For deeper browning, try roasting the radishes directly on a lightly oiled metal baking sheet instead of parchment paper. Direct contact with the hot metal may encourage better browning. Spread the radishes in a single layer, leave space between them, and check periodically to prevent burning.
Do roasted radishes taste like potatoes?
Not exactly, but roasting makes radishes much milder than when they’re raw. They become tender, lose much of their peppery bite, and make a satisfying low-carb alternative to roasted potatoes.
Why are my roasted radishes watery?
Radishes naturally contain a lot of moisture. Dry them thoroughly after washing, spread them in a single layer, and avoid overcrowding the baking sheet. Giving the moisture room to evaporate helps the radishes roast rather than steam.
