    I cut the recipe in half and used freshly blanched cauliflower as I find it retains more firmness which we like. I zipped up the cheese sauce with some garlic, and I used smoked paprika. Delicious substitute to cheesy potatoes. It is on my keeper list!

    This was disappointing. It was beyond bland even after adding more salt and even adding garlic. I'm sure I'll end up throwing this away.

    Followed the recipe precisely, easy to make. It tasted ok, just a bit bland. I will definitely make this again, but will add more S&P and ground mustard, and will probably add some garlic for sure!

    I made only a half a batch because there are only 2 in household. I didn't any other changes and it was very good.

    Excellent AND easy. I cubed some whole wheat toast for the croutons.

    Excellent taste and everyone loved it. I made it in the microwave in a covered stone cooker due to conflicts with the oven and it turned out great.

    Made this for dinner last night. I cut the recipe in half, added salt to the water when cooking the cauliflower and added a little extra salt and ground mustard to the sauce. It was delicious.

    This was such a family hit at Easter, I plan to make it again soon. I used seasoned crushed croutons in place of the bread crumbs. Many of our children thought they were potatoes!
