Ingredients

  • Cauliflower cut into florettes: The hero of the dish choose a firm head with bright white florets for best texture
  • Nutritional yeast: Brings a nutty cheesy depth Look for the golden flakes for the richest flavor
  • White wine vinegar: Lifts the sauce with subtle tang Pick a quality vinegar for a balanced bite
  • English mustard: Gives gentle heat and complexity Traditional English style works wonders here
  • White miso paste: Adds umami and creaminess Mellow white miso is less salty and blends smoothly
  • Tapioca starch: Ensures the sauce stays luscious and thick Buy fresh from a health food shop if possible
  • Vegan bechamel sauce: Forms the creamy base Make it from unsweetened plant milk and a roux for best results

Step-by-Step Instructions

Prepare the Cauliflower:
Break the cauliflower into small to medium florettes Rinse and drain well Fill a large pot with water and bring to a rolling boil Add a generous pinch of salt Once boiling tip in the cauliflower and simmer it for five minutes just until tender enough to pierce easily Drain immediately and arrange the hot florettes in your casserole or roasting dish spreading them out evenly for maximum sauce coverage
Mix the Flavor Base:
In a medium bowl combine nutritional yeast white wine vinegar English mustard white miso paste and tapioca starch Pour in three tablespoons of hot water This not only helps dissolve the starch and miso it wakes up all the flavors Whisk until the mixture is smooth and thick with no lumps remaining
Combine with Bechamel Sauce:
With your vegan bechamel sauce warm from the stovetop whisk in the entire flavor base mixture Keep stirring until everything is completely blended and silky smooth Remove from the heat so the sauce does not over thicken
Layer and Bake:
Instantly pour the finished sauce all over the cooked cauliflower in the dish Make sure every floret gets some of that glossy coating Transfer the dish to your oven and bake at a high temperature until the top is golden brown and bubbling around all the edges about twenty minutes
Serve and Enjoy:
Pull the dish from the oven and let it rest for about five minutes before serving This settles the sauce and makes serving easier Use a big serving spoon and prepare for clean plates

White miso is my favorite part of the sauce I love the subtle savory boost it gives which makes every bite extra comforting One of my fondest memories is serving this dish during a rainy weekend and everyone fought over the last spoonful

Storage Tips

Keep leftovers sealed in the fridge for three days Reheat gently in the oven or microwave to refresh the sauce If you want to meal prep freeze cooled portions in airtight containers and defrost overnight in the refrigerator before reheating

Ingredient Substitutions

If you do not have tapioca starch arrowroot or cornstarch work well instead Dijon mustard will substitute easily for English mustard Use chickpea miso or yellow miso if white miso is not available but opt for milder flavors to avoid overwhelming the sauce Swap in broccoli florets for a twist on classic flavor
