Roasted Radish Pesto Crostini

Roasted radishes on roasted garlic buttered crostini with radish green pesto dolloped on top, sitting on parchment paper

Warm, roasted radishes on top of garlic-buttered crostini, topped with radish green pesto is the perfect solution for a leftover bunch of radishes and their leaves.


  • 1 bunch of radishes with greens attached 
  • 5 cloves of garlic (3 left in their skins, 2 smashed and peeled)
  • 1 C olive oil, plus extra for drizzling
  • salt and pepper
  • 1 bunch of cilantro (including the stems), roughly chopped
  • 1C Parmesan, grated
  • a squeeze of lemon juice
  • 6 slices of crusty bread
  • 1/2 a stick of butter, softened 
  • flaky sea salt


  1. Preheat oven to 425 degrees. Cut the stems off the radishes; wash and roughly chop them and set aside. Cut the radishes into quarters. Drizzle the radishes and the 3 cloves of garlic in their skins with olive oil and season with salt and pepper. Toss together on a baking sheet and roast in the oven for 15 minutes, stirring and flipping over halfway through.
  2. Meanwhile, combine radish greens, the 2 cloves of smashed, peeled garlic, cilantro (and its stems), and a squeeze of lemon juice in a food processor; pulse to combine. With the processor running, drizzle in 1 C of olive oil. Stir in the Parmesan cheese, taste, and season with salt and pepper.
  3. When the radishes and garlic are done roasting, drizzle the bread lightly with olive oil on both sides and season with salt and pepper. Toast the bread in the 425 degree oven for 3-4 minutes per side.
  4. While the bread toasts, peel the roasted garlic cloves and mash with a fork on the baking sheet or on your cutting board. Combine the garlic with the softened butter, taste and season with salt and pepper.
  5. Spread the roasted garlic butter on the toasted bread, scatter roasted radishes on top, and dollop with radish green pesto. Sprinkle flaky sea salt on top and serve!


You’ll have pesto left over – it’s great tossed with pasta, or on top of pizza.
