Cauliflower, broccoli and blue cheese gratin

Cauliflower, broccoli and blue cheese gratin — Thermomix TM7

Cauliflower and broccoli gratin with Danish blue cheese is a comforting vegetable bake where the Thermomix TM7 steams the florets and blends a silky cheese sauce in one bowl. The tangy blue cheese melts into a creamy white sauce with dry wine, coating tender greens before baking to a golden finish. Ideal as a vegetarian main course or hearty side, ready with minimal hands-on effort thanks to precise temperature control.

About this recipe

Cauliflower, broccoli and blue cheese gratin Thermomix TM7 style brings a classic French-inspired oven bake within easy reach of any home cook. Searching for gratin recipes with your all-in-one kitchen machine usually stops at potato versions, yet this one pairs two cruciferous favourites with bold Danish blue cheese and a splash of dry white wine for a far more interesting result. The TM7 handles every stage in a single mixing bowl: you weigh the flour and butter directly into it, steam the cauliflower and broccoli florets to just-tender in the Varoma while the sauce base warms, then blend the milk, cheese and seasoning into a lump-free, velvety sauce with consistent stirring. Precise temperature control means the roux cooks gently without catching, while the steamed vegetables keep their bite instead of turning watery. Serve it as a vegetarian main course with crusty bread or a green salad, or as a luxurious side for a festive Sunday roast. It is exactly the kind of quick weeknight dinner that tastes like you spent hours at the hob.

Preparation tips

  • Cut the cauliflower and broccoli florets to a similar size so they steam evenly and finish at the same tenderness; uneven pieces leave some stems hard while tips turn soft. Pat the steamed florets dry before layering so the blue cheese sauce clings instead of thinning.
  • Crumble the Danish blue cheese while it is cold from the fridge, then add it off the heat so it melts gently into the sauce rather than splitting. Reserve a few crumbs to scatter on top before baking for extra savoury pockets.
  • For a milder family version, swap half the blue cheese for mature cheddar or Gruyère and reduce the white wine to a tablespoon. Leftovers keep well covered in the fridge and reheat beautifully in the oven the next day.

Recipe variations

  • Lactose-light version: replace the full cream milk with lactose-free milk and use a lactose-free blue-style cheese or a mix of feta and cheddar. Keep the butter-based roux but finish with a squeeze of lemon to lift the tang the blue cheese normally provides.
  • Festive winter variation: fold in roasted hazelnuts and caramelised shallots between the florets, top with grated Gruyère and breadcrumbs for a crunchy golden crust, and add a pinch of nutmeg to the sauce for a Christmas dinner side worthy of the roast.
