This is a new recipe that I recently tried out for Thanksgiving. It piqued another cook's interest so I said if it was good, I would post it. It is very good and tastes better reheated the next day!

  2. Cut enough cauliflower and broccoli into bite-size pieces to nearly fill the dish.

We really enjoyed this recipe - we had it at Christmas and at another large family event. I made the sauce the day ahead and I also steamed the vegetables, cooled them under cold water and refrigerated everything overnight. It was simple to throw everything together the next day and saved time and cleanup! The fresh basil and horseradish are really nice touches in the topping. Thanks Irmgard.

good recipe, I used zucchini instead of cauliflower. The only thing I would change would be use half the amount of bread crumbs.

Thanks for a great recipe Irmgard. I was able to prepare this the day before my big Christmas dinner and just added the crumbs before I put it in the oven on Christmas Day.It was enjoyed by all. I will be making this again. A great way to prepare broccoli and cauliflower.
