  • 2 pieces medium bunches radishes about 3 cups
  • 1 tablespoon neutral oil like avocado oil
  • 1 tbsp salt and fresh cracked pepper
  • 2 tablespoons butter see Note
  • 1 clove garlic pressed or minced
  • 1/4 teaspoon lemon zest optional
  • 1 piece fresh thyme sprigs optional


  1. Preheat oven to 450º F.
  2. Prepare radishes: slice off the stems and any tail on the root (The part trailing off the radish itself). Halve small and medium radishes; quarter larger radishes.
  3. Spread radishes on a baking sheet and toss with oil and lots of salt and fresh cracked pepper. Roast 20-30 minutes, stirring every 10 minutes, until browned in spots and a bit wrinkled but not burned.
  4. While radishes roast, brown your butter. Heat butter in small light-colored saucepan or skillet over medium heat. Watch butter carefully over 3-5 minutes until it becomes a deep, toasty brown and smells nutty. Remove from heat immediately when it turns this color or begins to smell nutty.
  5. Let browned butter rest 2-3 minutes then stir in garlic and a pinch of salt, stirring well until garlic is slightly cooked and softened and fragrant.
  6. When the radishes are finished roasting, remove from oven and pour browned butter sauce over. Toss; sprinkle with lemon zest and thyme sprigs, if desired. Serve immediately.

Recipe Notes

For Whole30, use homemade browned butter ghee or packaged brown butter ghee. Alternately, simply heat plain ghee over medium heat then stir in garlic, cooking until fragrant, about 30-60 seconds. Remove from heat immediately and let sit until radishes are finished roasting.

For vegan, use Miyoko's vegan butter in place of regular butter.
