Broccoli & Onion Au Gratin

Recipe by keen5

Broccoli and onion in a creamy Swiss cheese sauce with rosemary. I found this in my Treasury of Country Recipes cookbook. There is a picture of it and it looks delicious, but I haven't tried it yet. Cook time is for baking only, not for the cheese sauce.

I came out very impressed with this recipe! I was a little concerned at first as rosemary is quite pungent, but it works perfectly here. After cleaning and cutting my broccoli I had about 3 1/2 cups so I upped the sauce by 50%, then I was just a 1/2 c short of swiss so I added some cheddar and they blended together fantastic. I kept the bread crumbs the same ratio. I also wedged the onion smaller. It looked so elegant! And tasted wonderful. Another keeper and I like that it is a different twist on the old broccoli casserole.
