Roasted Radishes Garlic Butter

The first time I served roasted radishes, my brother thought they were baby potatoes. He kept eating them, genuinely confused, until I finally confessed. Now it is our little spring tradition, watching peoples faces when they realize how mellow and sweet radishes can become.

Last Easter, I made these alongside roast lamb and my aunt actually asked for the recipe right there at the table. Something about roasting completely changes their personality, turning that sharp bite into something almost like a mild turnip but prettier.

Ingredients

• 500 g radishes: Look for firm, bright radishes without soft spots and leave a bit of the stem on for prettier presentation
• 2 tbsp unsalted butter: Butter carries the garlic and thyme flavor better than oil alone and adds richness
• 1 tbsp olive oil: The higher smoke point prevents burning in the oven while butter provides flavor
• 2 garlic cloves: Mince them finely so they dissolve into the butter rather than staying chunky
• 1 tbsp fresh thyme: Fresh thyme has a softer, more floral flavor than dried but use dried if that is what you have
• Sea salt and pepper: Radishes need salt to balance their natural bitterness

Instructions

Prep the oven:

Preheat to 220°C (425°F) and line a baking sheet with parchment paper for easy cleanup.

Season the radishes:

Toss halved radishes with olive oil, salt, and pepper in a large bowl until evenly coated.

Arrange for roasting:

Spread radishes cut-side down in a single layer so they get nicely caramelized.

Roast until tender:

Roast for 20 to 25 minutes, stirring halfway through, until golden and easily pierced with a fork.

Make the garlic butter:

Melt butter in a small skillet over low heat, add garlic and thyme, and cook for 1 to 2 minutes until fragrant but not browned.

Finish and serve:

Toss hot radishes with garlic butter, garnish with fresh thyme and flaky salt, and serve while still warm.

My daughter now requests these as her favorite vegetable, which still surprises me. Watching someone who swore they hated radishes go back for thirds is pretty satisfying.

Choosing the Best Radishes

Spring radishes are smaller and sweeter, while fall varieties can be sharper. If your radishes seem particularly peppery, try soaking them in ice water for 30 minutes before roasting.

Making It Your Own

Lemon juice added right before serving wakes everything up. Sometimes I toss in some roasted baby carrots with the radishes for a colorful mix.

Timing Everything

The garlic butter can be made ahead and gently reheated while radishes roast.

• Start checking the radishes at 20 minutes since smaller ones cook faster
• Keep the butter warm but not hot so it does not separate
• Season again right before serving with a little extra flaky salt

These are best eaten warm from the oven, when the butter still glistens and the thyme is most fragrant.
