Instructions

  1. Heat the oven to 375°F (190°C) and butter an 8 × 8-inch (20 × 20 cm) baking dish.

  2. Boil the florets in salted water for 4–5 minutes (or steam for 5–6), until a fork goes in with slight resistance. Drain thoroughly and spread them on a towel to steam-dry for 5 minutes, patting the tops.

  3. In a large saucepan over medium-low heat, warm the cream, cream cheese and butter, whisking until smooth and steaming — don't let it boil.

  4. Take the pan off the heat. Add the cheddar a handful at a time, stirring until each addition melts, then whisk in the mustard powder, garlic powder, salt and pepper. The sauce should be thick and glossy.

  5. Fold in the cauliflower until every piece is coated and spread it in the dish. Sprinkle with the parmesan, paprika and pork rinds, if using.

  6. Bake 15–20 minutes, until bubbling and lightly golden, then rest 5 minutes. In a hurry? Skip the oven and serve it straight from the pot as creamy stovetop mac.

Tips for success

  • Mustard powder is the classic mac & cheese trick: it doesn't taste like mustard, it just makes the cheddar taste sharper and cheesier.
  • Melt the cheese off the heat. Overheated cheese squeezes out its fat and turns grainy; gentle residual heat keeps the sauce silky. For a pourable version to use on other dishes, see velvety cheese sauce.
  • Cut the florets about the size of large macaroni so every bite gets plenty of sauce, and top with pork rind "panko" for a crunchy baked crust.

Nice to have, not needed

  • Crushed pork rinds give a crunchy baked top — leave them off for a softer, creamier finish.

Storage & meal prepMeal-prep friendly

  • Keeps 4 days in the fridge
  • Doesn’t freeze well

Reheat: Reheat covered in a 350°F (175°C) oven for 15–20 minutes, or microwave portions with a splash of cream, stirring halfway.

Prep tip: Bake it in individual oven-safe containers so each portion reheats evenly.

Refrigerate up to 4 days. Reheat covered in a 350°F (175°C) oven, or in the microwave with a splash of cream, stirring halfway.
