Roasted Radishes
with Garlic & Herbs
The low-carb potato substitute you didn't know you needed. Raw radishes lose their sharp, peppery bite completely when roasted at high heat — turning tender, mild, and slightly sweet with golden caramelized edges. Tossed in garlic-herb oil and ready in 30 minutes, this is a game-changing side dish for anyone missing roasted potatoes.
- 1 bag radishes, halved (quartered if large)
- 2 tbsp olive oil
- 2 cloves garlic, minced
- 1 tsp fresh rosemary, finely chopped (or ½ tsp dried)
- 1 tsp fresh thyme leaves (or ½ tsp dried)
- ½ tsp salt
- ½ tsp black pepper
- — fresh parsley, to garnish (optional)
- — flaky sea salt, to finish (optional)

1
Preheat & prep
Preheat oven to 400°F. Line a baking sheet with foil. Wash and dry the radishes thoroughly — excess moisture will steam them instead of roasting them. Halve each radish, quartering any particularly large ones so everything is roughly the same size for even cooking.

Make the garlic herb oil
In a small bowl, combine the olive oil, minced garlic, rosemary, thyme, salt, and pepper. Stir to combine.

Coat & arrange
Add the radishes to a large bowl, pour the garlic herb oil over the top, and toss until every piece is evenly coated. Spread in a single layer on the prepared baking sheet cut-side down — this is what gives you the best caramelization on the flat side.

Roast
Roast at 400°F for 20–25 minutes, flipping once halfway through, until the radishes are tender when pierced with a fork and the cut sides are golden and caramelized. They should look nothing like a raw radish at this point.

Garnish & serve
Transfer to a serving dish and finish with a scatter of fresh parsley and a pinch of flaky sea salt if desired. Serve immediately while hot.
- The transformation is real: First-timers are always surprised — roasted radishes taste nothing like raw radishes. The sharp, peppery bite disappears completely and they become mild, tender, and slightly sweet. Perfect for anyone missing roasted potatoes.
- Cut-side down matters: Placing the radishes cut-side down on the baking sheet maximizes the flat surface contact with the hot pan — this is what creates those beautiful golden caramelized edges.
- Don't crowd the pan: Give each piece a little space so they roast rather than steam. Use two baking sheets if needed.
- Serve in slow cooker dishes: Roasted radishes are a great low-carb addition to our Horseradish Roast and Slow Cooker Pot Roast — just tuck them in alongside the other vegetables.
- Season variations: These are delicious with everything bagel seasoning, smoked paprika and cumin for a Tex-Mex vibe, or simple lemon and Parmesan for an Italian feel.
