Kitchen Equipment You’ll Need

  • Large pot
  • Baking sheet

Step-by-Step Preparation: How to Make Smashed Rosemary Garlic Roasted Radishes

Step 1 – Boil the Radishes

Bring a large pot of salted water to a boil. Add radishes and cook for 15–20 minutes until fork-tender.

Step 2 – Preheat Oven

Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper.

Step 3 – Smash the Radishes

Drain radishes and place them on the baking sheet. Using a potato masher or glass, gently press each radish until flattened but still intact.

Step 4 – Season

In a small bowl, mix olive oil, garlic, rosemary, salt, and pepper. Brush or drizzle mixture over smashed radishes.

Roast for 20–25 minutes until edges are golden and crispy.
