Helpful Recipe Tips

  • Smooth cream sauce, the key to a smooth sauce is the order you add ingredients into the pot. Not to mention whisking instead of stirring makes a difference. If something goes wrong the sauce and be grainy instead of smooth.
  • Use oil to carry xanthan gum, you must use oil to carry the xanthan gum and for it to remain smooth. The small bit of water in butter will cause it to clump resulting in a grainy sauce.
  • Use fresh broccoli for this recipe. Frozen broccoli will release water into the casserole and don't cook the broccoli first . If you do the broccoli will be mushy by the time the casserole is finished.
