"made this for Easter dinner. it was a great hit. next time I will adjust the cheese levels to make it a bit healthier. Not sure if I had small heads (they were average in store) but definitely would not have served 12"

"Mmmm - great combination. I put in three dollops of organic sour cream, 1/2 tsp. granulated garlic, moistened with 1/2 cup cooking water, 1 cup grated Parmesan & skipping the bread crumbs. Putting the cheese combo on top to bake."

"This was very good. I didn't have the steak seasoning or the garlic salt so I just added salt and pepper. I will definitely make this again."

"My husband and I love this. I only make about half of the recipe. I probably end up with a little more cheese by doing this, but we love cheese. Be sure to use freshly grated parmesan cheese."
