    Hello shelbyrose, 1 lb of frozen pearl onions is what we used, kicked-it-up a notch by adding salt, black grnd pepper, & a sprinkling of crushed red pepper. Used a spicy cheddar, mild cheddar combination. It is a great dish as is, but for "our tastes" I just added the above. I love onions and mushrooms, and this just gives us a new way to prepare them! Thank you muchly(sp?) for posting, Diane :)

    I enjoyed this recipe very much. I'm not sure if there's a typo, but 24 pearl onions is hardly any for all that sauce, so I just used 1 pound and it was still very saucy and thick. I used frozen thawed pearl onions for easy preparation. I did put salt and white pepper in the sauce, but it still could use a bit more something to liven it up. Perhaps some cheese in the sauce as well as on top? More spices? Instead of making 2 casseroles, i made 1 large one. Thanx for posting this. I will play around with it and definitely make it again!
