  • 2 heads Cauliflower
  • ¼ cup Olive Oil
  • ½ teaspoon Salt
  • ½ cup Butter salted
  • 4 tablespoons Capers
  • ½ cup Walnuts
  • 1 Lemon


  • Preheat oven to 425 degrees F.
  • Slice cauliflower into 1 inch thick “steaks”.
  • Brush both sides of cauliflower steaks with olive oil and place them on a baking sheet. Do not use parchment paper or a silicone baking mat or you won’t get the beautiful caramelization.
  • Sprinkle with salt and place in oven to bake for approximately 10 minutes, the cauliflower should have a nice brown color to it before flipping. Then flip and continue to bake for another 10 minutes.
  • While the cauliflower bakes make your browned butter. Add the butter to a hot pan over medium heat.
  • As the butter cooks it will foam and then you will see little brown bits begin to form on the bottom. When the color of the butter reaches a deep golden-brown color it is done. Pour the brown butter into a bowl. You can strain the butter to remove the brown bits on the bottom or not. It’s up to you!
  • Add the capers and walnuts to the skillet over medium heat and lightly toast them for 2-3 minutes. Then add the brown butter back to the pan.
  • When the cauliflower has finished baking remove it from the oven and spoon the brown butter, capers, and walnuts over the cauliflower steaks.
  • Squeeze the lemon over the cauliflower and serve.
