For best results, use freshly grated Parmesan cheese. To prevent tearing up while slicing onions, chill them in the refrigerator for at least 30 minutes prior. Feel free to experiment with different types of crackers for the topping. This casserole can be assembled ahead of time and refrigerated until ready to bake. Add about 10 minutes to the baking time if baking from cold.
