“This cauliflower-and-broccoli gratin is healthier than traditional gratins thanks to a sauce made with low-fat milk and just enough full-flavored cheese to keep it rich without extra saturated fat and calories. For a healthier cheese-crust topping, opt for cheese crackers made without partially hydrogenated oils. ”


    • 14 cups bite-size florets from 2-3 heads broccoli, cauliflower and/or romanesco
    • 2 cups low-fat milk
    • 1½ teaspoons Dijon mustard
    • ½ teaspoon garlic powder
    • ½ teaspoon salt
    • 2 tablespoons cornstarch
    • 2 tablespoons water
    • ¾ cup shredded extra-sharp white Cheddar cheese
    • ¾ cup shredded Gruyère cheese
    • ¼ cup snipped fresh chives
    • ¾ cup crushed cheese-flavored crackers
    • 2 teaspoons extra-virgin olive oil


  • 1 Bring a large pot of water to a boil. Add florets and cook, stirring frequently, for 1 minute. Drain in a colander and immediately rinse with cold water until cool. Drain well. Spread on a baking sheet or kitchen towel and pat with a clean towel to soak up any excess water.
  • 2 Preheat oven to 375°F. Coat a 9-by-13-inch (or similar-size shallow ovenproof dish) with cooking spray.
  • 3 Combine milk, mustard, garlic powder and salt in the large pot; bring to a simmer over medium-high heat. Combine cornstarch and water in a small bowl; whisk into the simmering milk. Bring the mixture to a boil over high heat, whisking. Reduce heat to maintain a simmer and cook, whisking, for 2 minutes. Add Cheddar, Gruyere and chives; whisk until smooth. Remove from heat.
  • 4 Add the florets to the pot and gently stir to coat with the cheese sauce. Transfer to the prepared baking dish. Combine crackers and oil in a small bowl and sprinkle over the vegetables.
  • 5 Bake until the cheese sauce is bubbling and the florets are starting to brown on top, 25 to 30 minutes. Serve warm.
  • Make Ahead Tip: Prepare through Step 1, cover and refrigerate florets for up to 1 day. Proceed with Steps 2-5 about 1 hour before serving.
