  • 1 small head broccoli, cut into florets
  • 1 small head cauliflower, cut into florets
  • 4 tablespoons unsalted butter
  • 1 small onion, finely chopped
  • 2 large cloves of garlic, minced
  • 1/4 cup all-purpose flour
  • 1 1/2 cups whole milk
  • 3/4 cup low-sodium vegetable broth
  • 2 1/4 cups shredded artisanal white cheddar
  • Pinch of freshly ground nutmeg
  • Salt & pepper to taste

Crumb Topping:

  • 20 Ritz crackers
  • 1 teaspoon dried oregano
  • 1/2 teaspoon onion powder
  • 3 tablespoons melted butter


  1. Preheat and Roast: Preheat your oven to 400 degrees. Spray a generously sized baking dish with nonstick baking spray. Arrange broccoli and cauliflower, roasting for 15 minutes or until they achieve a delicate golden brown hue.
  2. Savory Sauce: In a large skillet over medium heat, melt butter. Add finely chopped onion, cooking for 5 minutes. Introduce minced garlic, sautéing for an additional 30 seconds. Whisk in flour, cooking for 90 seconds while whisking constantly. Gradually introduce milk and vegetable broth, alternating between the two. Reduce heat to low, add cheddar, and whisk until the cheese melts, creating a smooth and creamy mixture. Incorporate nutmeg and season with salt & pepper to taste. Pour this luxurious sauce over the roasted broccoli and cauliflower.
  3. Zesty Crumb Topping: In a food processor, pulse the Ritz crackers until crushed. Add oregano, onion powder, and melted butter, pulsing a couple of times. Sprinkle this zesty crumb topping over the cheese sauce.
