Parmesan cheese is not truly vegetarian, as it contains animal rennet. To make this dish 100% vegetarian, omit the cheese or find a suitable vegetarian substitute made without animal rennet. In supermarkets look for the 'parmesan style hard cheeses' which are suitable for vegetarians.
Love it! I bought the broccoli sprouts but didn't want to eat it boiled again and didn't know what else to do with it. I am so glad I found your recipe. I added mild cheddar instead Parmesan cheese and still it was very yummy. I had freshly baked walnut bread to go with it. - 11 Sep 2011
Used mature cheddar instead of parmesan and served with a Texas rubbed brisket of beef and roast potatoes. Will be on the menu again soon - 23 Feb 2014
Wonderful recipe. The broccoli is flavorful, tender, and crispy at the edges. My family loved it. I would definitely make it again (and again)! - 19 May 2013 (Review from Allrecipes AU | NZ)
