    1. HI,

      I am wondering if this could be frozen rather than left in the fridge. I live alone so would prefer to have it available for later rather than over a few nights especially during the winter months.

      Definitely lives up to its name. Creamy. Low carb. Easy. I added a dash of nutmeg as I do with beschamel sauces. It comes out looking exactly like the picture on the recipe page. I served it with a ribeye steak and a small lobster tail at Easter dinner. I assembled it early in the day and just had to pop it in the oven when I was ready to cook. As another reviewer said, you can gussy it up in many ways and by adding cheese in sauce,, but I didn’t want to make our dinner any heavier than it was with the other parts of the meal. I sprinkled a little paprika on top. Just make sure you taste for enough salt before baking, and you’re good to go.

      I added some cheddar cheese to the white sauce and it made it a bit thicker but it was delicious. ..I think I’ll try some fontana cheese next time…great recipe ….thank you.

      Could I cook this for 15 mins leave to cool gift it and tell the recipient to just bake for 5 mins at 200c ?

      1. Hi Natalie, to tell the truth I would cook it completely then just re-heat it at 300F for about 10 minutes or until heated through. Hope that the helps. Let me know how it goes.
