Creamy Squash Casserole with Ritz Crackers Recipe FAQs
How do you choose yellow squash for the casserole?
Absolutely! When selecting yellow squash, look for firm ones with a glossy skin, avoiding any that have dark spots or wrinkles. The squash should feel heavy for its size, ensuring freshness and flavor for your creamy squash casserole with Ritz crackers.
How can I store leftovers?
You can store leftover squash casserole in an airtight container in the fridge for up to 3 days. Just be sure to cover it well; this helps keep it moist and prevents it from drying out. If you press for time, just grab it out the night before and it’s ready to go!
Can I freeze this casserole?
Absolutely! For long-term storage, freeze the casserole before baking by wrapping it tightly in plastic wrap and then aluminum foil. This way, it will remain fresh for up to 2 months. When you’re ready to enjoy, thaw it in the fridge overnight before baking at 350ºF for 25-30 minutes.
What should I do if the casserole turns out watery?
Very! If your casserole ends up watery, it could be due to not draining the squash well enough. To prevent this, after cooking the squash and onions, let them drain in a colander for a few minutes. You can also consider adding a bit more cheese or breadcrumbs, as they absorb excess liquid nicely.
