Dinner

March 9, 2026

Introduction

Ever wonder what to do with that bunch of radishes? Forget salads! When roasted, their sharp bite mellows into a surprisingly sweet, earthy flavor. The texture becomes so tender and satisfying, it reminds me of the new potatoes my papa pulled from his garden. Tossed in rich garlic butter, these roasted radishes become an irresistibly simple side dish that might just become your new favorite low-carb swap for potatoes.

Ingredients

• 1 pound / 450g radishes, trimmed and halved
• 3 tablespoons / 42g salted butter, melted
• 2 cloves garlic, minced
• Coarse sea salt, to taste
• Freshly ground black pepper, to taste

Instructions

1. Preheat your oven to 425°F / 220°C and line a large baking sheet with parchment paper.
2. In a medium bowl, toss the trimmed and halved radishes with the melted butter and minced garlic until evenly coated.
3. Spread the radishes in a single, even layer on the prepared baking sheet. Sprinkle generously with salt.
4. Roast for 25 minutes, turning them halfway through, until the radishes are tender and slightly golden brown.
5. Garnish with freshly ground black pepper and serve immediately.
