Let’s embark on a culinary journey to create this indulgent yet wholesome masterpiece.


  • 1 small head broccoli, cut into florets
  • 1 small head cauliflower, cut into florets
  • 4 tablespoons unsalted butter
  • 1 small onion, chopped
  • 2 large cloves of garlic, minced
  • 1/4 cup all-purpose flour
  • 1 1/2 cups milk
  • 3/4 cup low-sodium chicken broth
  • 2 1/4 cups shredded white cheddar
  • Pinch of 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 the Oven: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish and set aside.
  2. Prepare the Vegetables: Steam the broccoli and cauliflower florets until just tender, about 5-7 minutes. Drain and set aside.
  3. Make the Cheese Sauce: In a large skillet, melt 4 tablespoons of butter over medium heat. Add the chopped onion and minced garlic, cooking until softened and fragrant, about 3-4 minutes. Sprinkle the flour over the mixture and cook, stirring constantly, for 1-2 minutes to create a roux.
  4. Add Liquid Ingredients: Gradually whisk in the milk and chicken broth, stirring until the mixture is smooth and thickened, about 5 minutes. Reduce the heat to low and stir in the shredded white cheddar cheese until melted and smooth. Season with a pinch of nutmeg, salt, and pepper to taste.
  5. Combine with Vegetables: Add the steamed broccoli and cauliflower to the cheese sauce, tossing gently to coat the vegetables evenly.
  6. Prepare the Crumb Topping: In a food processor, pulse the Ritz crackers until they form coarse crumbs. Transfer the crumbs to a bowl and mix in the dried oregano, onion powder, and melted butter until well combined.
  7. Assemble and Bake: Transfer the cheesy cauliflower mixture to the prepared baking dish. Sprinkle the crumb topping evenly over the top.
  8. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the sauce is bubbly.
  9. Serve: Remove from the oven and let it cool for a few minutes before serving. Garnish with fresh parsley if desired.

Cook’s Notes and Variations:

  • Bacon Bits: For added flavor, sprinkle cooked and crumbled bacon over the top before baking.
  • Vegetable Variations: Feel free to add other vegetables such as carrots, peas, or spinach to the cauliflower and broccoli mixture for extra color and nutrients.
  • Cheese Options: Experiment with different types of cheese such as gruyere, fontina, or gouda for unique flavor combinations.
  • Creamy Texture: For an even creamier sauce, add a dollop of sour cream or Greek yogurt to the cheese sauce mixture.

Keto and Low-Carb Versions:

  • Keto: Substitute the all-purpose flour with almond flour or coconut flour to thicken the sauce and omit the Ritz crackers for the topping. Use crushed pork rinds mixed with Parmesan cheese for a crispy keto-friendly topping.
  • Low-Carb: Similar to the keto version, use low-carb flour alternatives and opt for a low-carb breadcrumb substitute for the topping. Crushed pork rinds or crushed almond flour crackers can work well in place of Ritz crackers.
