Begin by prepping your radishes. Trim the ends and cut any large radishes in half or quarter them.

Toss the halved radishes in a mixing bowl with about ½ tablespoon of olive oil, ensuring they're evenly coated.

Place the prepared radishes in your air fryer basket and cook at 400°F (200°C) for 8 minutes.

Check for tenderness by piercing them with a fork; they should be soft but not falling apart.

While the radishes cook, combine the remaining olive oil, crushed garlic cloves, kosher salt, red pepper flakes, and parsley flakes in a separate bowl.

Once the initial cooking is complete, transfer the radishes back into the mixing bowl.

Pour the prepared seasoning mixture over them and gently toss to coat.

Sprinkle in about ¼ cup of grated Parmesan cheese, stirring slowly until the radishes are fully covered.

Return the coated radishes to your air fryer for the final cook at 400°F (200°C) for an additional 6-8 minutes.

Keep an eye on them to achieve a golden brown and crispy finish.
