If you have any leftovers let them cool and put them in a refrigerator dish or plastic storage bag. It will keep in the refrigerator for about 5 days. Reheat in the microwave for a minute or two (depending upon amount your a reheating) until hot. The crackers will not be crisp, but the dish still tastes very flavorful and rich. You can also reheat in the oven in an oven-safe dish at 350°F until hot. Or if you use an air fryer, reheat on high in an oven safe dish until hot and bubbly.

No one likes a watery casserole. To keep this from happening, cook squash before mixing casserole ingredients. If you boil squash, add salt to the water and then drain completely and blot dry with a paper towel before combining all casserole ingredients. The salt helps pull water out of the squash so it doesn’t release water while cooking as a casserole.
You can, but it is not necessary. I prefer to leave the skin on and enjoy the vitamins and rich yellow color in the dishes I prepare.
Yes. Salt the squash and let it set for 30 minutes. You can also boil in salted water. Salt helps release water trapped in the vegetable making a less watery final product.
