Notes

  • Swap cheddar for Gruyère or Red Leicester for varied flavor.
  • Add smoked paprika to breadcrumbs for warmth.
  • Use single cream instead of double for a lighter sauce.
  • Add steamed broccoli florets alongside cauliflower before saucing.
  • Make vegan by substituting cream, cheese, and butter with plant-based alternatives.
