For the crunchiest topping, wait until the last 10-15 minutes of baking to scatter those golden onions over your casserole. This way, they get perfectly crisp and beautifully browned, without turning soggy. Don’t worry your casserole will still have that nostalgic, oniony goodness woven throughout.
