Ingredients

  • 1 pound parsnips, peeled
  • 1 pound sweet potatoes, peeled
  • 1 pound red beets, peeled
  • ¼ cup olive oil, divided
  • 2 ½ teaspoons salt, divided
  • 3 tablespoons all-purpose flour
  • 3 cups whole milk
  • 2 cloves garlic, minced
  • 1 tablespoon fresh sage, chopped
  • ½ teaspoon black pepper
  • ½ cup Swiss cheese, grated
  • ⅓ cup Panko breadcrumbs
  • ¼ cup Parmesan cheese, grated

Instructions

  1. Preheat oven to 425 degrees. Line a baking sheet with aluminum foil and grease a 9-by-13-inch baking dish with nonstick cooking spray. Set aside
  2. Slice parsnips, sweet potatoes and beets into thin rounds with a knife or mandoline. Place each vegetable in a separate small bowl and toss each with 1 teaspoon oil and ⅓ teaspoon salt. Arrange vegetables on prepared baking sheet, keeping them separated, and roast for 15 minutes. 
  3. While vegetables roast, prepare the sauce. In a medium saucepan over medium heat, whisk together 2 tablespoons oil and flour. Cook while whisking for 1 to 2 minutes. Add the milk, garlic, sage, remaining 1 ½ teaspoon salt and pepper. Cook while whisking until sauce has thickened slightly, about 4 to 5 minutes. Remove from heat and whisk in the Swiss cheese until smooth. Set aside. 
  4. Return cooked vegetables to the three separate bowls used in step 2 and toss each with about a third of the sauce. Arrange the vegetables in the prepared baking dish in rows, beginning with the parsnips, then sweet potatoes, then beets.
  5. In a small bowl, whisk together the breadcrumbs, Parmesan and remaining tablespoon oil. Sprinkle breadcrumb mixture over the vegetables and bake for 45 minutes to 1 hour, or until golden brown. Serve warm.
