This creamy gratin bakes for 20 minutes, then finishes under the broiler to make the top beautifully browned and crunchy. You can also try it with broccoli.

This recipe has potential. I agree with other reviewers that it lacked an "it" factor. Vegetables were the perfect texture. I used heavy whipping cream and an American swiss cheese since that was what I had on hand. The bacon was crumbled over the top before serving which provided an occasional nice bite of flavor. Maybe add tomatoes next time?

I thought this was great. I love brussel sprouts and califlower, so this was a match made in heaven. As with most recipes, I didn't follow it exactly because I didn't have everything on hand, so I used 2% instead of 1/2 & 1/2 and 1%, 3 slices of regular bacon instead of 4 of the center cut and only had 1/2 of a yellow onion (@ 1 cup) and it still turned out yummy! 1 of the people eating it hates brussel sprouts and went back for seconds. I will make this again for sure and wouldn't hesitate to serve it to company. I love Cooking Light!!

So much work with so little payoff! One of the only times we've ever had to order pizza because of a meal failure. Soggy and bland.

I was so happy that this came out wonderful,and my dish came out just like the photo in CL! I added some leftover broccolini I had in the fridge, for some more green. 3 minutes under a low broiler was enough to brown the top. My husband (not a big veggie fan) had 2 servings! It is also great leftover. It does not taste like a "light" recipe. I will make this again.

This was good, but a lot of prep work, so time consuming. The end product had a very runny sauce. Had to use a slotted spoon to serve. Did not have 1% so used fat free milk. Maybe that contributed to the problem and/or maybe because the casserole was covered. Will try baking uncovered next time.

In the 10 years I've been with cooking light, I think this is the 1st time I've rated anything a 1. Even the bacon couldn't save it! We love brussels sprouts and cauliflower, but not like this. Think I will stick to roasting it. Also, it was a lot of work.

I made this and fell in love! It is absolutely scrumptious. I made it with fat-free milk and didn't use any bacon and it was still completely flavorful and enjoyable. I made a full recipe and have been eating it for lunch or dinner every day since. I don't want to share it with my family! I definitely recommend this, an exceptional dish.

I have hundreds of Cooking Light recipes which I love - this is not one of them. This recipe was not worth the trouble. You end up with a relatively rich dish that is just not that tasty, and you lose the real essence of the vegetables. I did not like the flavors -- thought the bacon detracted from the final product. There are much better brussels sprouts and cauliflower options on this site.

I made this for a family dinner so I'd have a vegetable dish that could be done in advance. I used broccoli and cauliflower, added some peppers for color. It was fabulous! I'll make this many times with whatever vegetables I have on hand.

Made for Sunday dinner but this would be a great holiday side, too. Blanched the vegs & prepped bacon/onion/garlic earlier in the day so the rest came together quickly. Served with CL's Italian meat loaf. Very good.
