  • 2 bunches radishes about 3 cups
  • 1 tablespoon neutral oil like avocado oil
  • 1 tablespoon salt
  • 1 tablespoon freshly cracked black pepper
  • 2 tablespoons butter see Notes
  • 1 clove garlic pressed or minced
  • ¼ teaspoon lemon zest optional
  • 1 piece fresh thyme sprigs optional


  • Preheat oven to 450º F.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.


  • Make it 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.
  • Make it Vegan: use Miyoko's vegan butter in place of regular butter.
