Rich Landau’s earliest holiday memories revolve around turkey. “My Thanksgiving was straight out of a Norman Rockwell painting,” he says. Things have changed since then: Rich and his wife Kate Jacoby own two vegan restaurants, Vedge in Philadelphia and Fancy Radish in Washington, DC. Vegetables now have the starring role at their holiday meals—in this case, a whole cauliflower roasted with traditional Thanksgiving herbs. “The holiday is about flavors, not turkey,” he says. If you want to make this cauliflower feel like a classic feast, set up a carving station!


For the Roasted Garlic:

For the Glaze and Cauliflower:


  1. Make the roasted garlic: Preheat the oven to 400˚ F. Cut the top 1 inch off the garlic heads and place on a large sheet of foil, cut-sides up. Drizzle with the olive oil and season lightly with salt and pepper. Wrap the foil around the garlic heads and bake until the garlic is browned and soft, about 1 hour. Remove from the oven and unwrap. When cool enough to handle, squeeze the garlic cloves out of their skins. You should have about 1 cup roasted garlic.
  2. Bring a large pot of salted water to a boil. Meanwhile, make the glaze: Combine the roasted garlic, olive oil, Dijon mustard, shallot, vegan mayonnaise, 1 teaspoon salt, 2 teaspoons pepper, the sage and rosemary in a blender and puree until smooth. Transfer the glaze to a bowl and stir in the grainy mustard.
  3. Working in batches if needed, add the cauliflower to the boiling water and cook until slightly puffed and yellowed, 8 to 10 minutes. Drain and let cool.
  4. Preheat the oven to 400˚ F (use the convection setting, if available). Transfer the cauliflower to a rimmed baking sheet. Brush with the sunflower oil and sprinkle with 2 teaspoons each salt and pepper. Bake 10 minutes.
  5. Remove the cauliflower from the oven and pour the mustard glaze evenly over each head. Return to the oven and bake until the glaze turns golden brown, 8 to 12 minutes.

Cook’s Note

If your cauliflower heads are tightly packed, boil them a little longer.
