Step‑By‑Step Instructions

Follow these simple steps to make the dish:

  1. Cut and steam: Chop the cauliflower into bite‑sized florets. Steam until tender but not mushy, then drain and let cool slightly.
  2. Make the cheese sauce: Warm the heavy cream over medium‑low heat. When it begins to simmer, add shredded cheese, garlic powder, oregano (if using), salt, and pepper. Stir until the cheese melts and the sauce is smooth.
  3. Thicken: Sprinkle xanthan gum over the sauce and whisk or stir it in thoroughly. Let the sauce rest for about five minutes to thicken.
  4. Combine and serve: Pour the sauce over the steamed cauliflower and toss to coat every floret. Serve immediately while warm.

How to Store It

If you have leftovers, store them properly to keep the texture and flavor:

  • Refrigerate: Transfer to an airtight container and keep in the fridge for 3–4 days. Reheat gently to preserve creaminess.
  • Freeze: Freeze in a freezer‑safe container or resealable bag, removing as much air as possible. Label and freeze for up to three months. Thaw and reheat in a microwave or oven.
