Your dinner guests will never know you started with frozen vegetables after broccoli and cauliflower have been roasted and topped with homemade garlicky breadcrumbs. You can make the breadcrumbs the day before and store them at room temperature in an airtight container.

Roasted Cauliflower and Broccoli with Lemony Garlic Breadcrumbs

4 to 6 servings


  • One 16-ounce bag frozen broccoli, thawed
  • One 16-ounce bag frozen cauliflower, thawed
  • 3 tablespoons unsalted butter
  • 2 tablespoons extra-virgin olive oil
  • Kosher salt and freshly ground black pepper
  • 1 large clove garlic, finely grated 
  • 5 tablespoons panko breadcrumbs
  • 1 tablespoon fresh parsley leaves, finely chopped
  • Zest of 1 lemon


Position an oven rack in the center of the oven, set a rimmed baking sheet on it and preheat to 450 degrees F. 

Dry the broccoli and cauliflower as well as possible between paper towels. Melt 2 tablespoons of the butter in a large bowl in the microwave. 

Add the vegetables and oil to the butter, and toss to coat. Carefully remove the preheated baking sheet from the oven, and spread the vegetables on it in an even layer; sprinkle all over with 1 teaspoon salt and 1/4 teaspoon pepper. Roast until the vegetables are dark brown on the underside and in spots around the edges, about 30 minutes. 

Meanwhile, heat the remaining 1 tablespoon butter in a medium skillet over medium heat. Add the garlic, and cook, stirring constantly, until lightly golden, 1 to 2 minutes. Add the breadcrumbs, and stir until toasted and golden brown, 2 to 3 minutes. Remove from the heat, and stir in the parsley, lemon zest and 1/2 teaspoon salt. 

Transfer the vegetables to a serving platter, and sprinkle with the lemon-garlic breadcrumbs.
