How To Stop Your Squash From Getting Watery

One of the most common problems for home cooks when working with squash is its tendency to get really watery.

This unfortunate watery-ness results in the whole dish tasting vaguely bitter and having a little bit too much liquid.

To avoid this, make sure that you do not actively boil your squash when cooking it. You are really looking to actually steam your squash, not boil it in water.

The steaming will allow the natural moisture within the squash to release, gradually cooking it and eventually releasing its liquid. From there, you can drain all of that potentially bitter and unwanted liquid and add it straight to your recipe!

You can also press out all of the excess moisture from the squash with your hands once it is done cooking if you like. This should help expel every last drop of water and result in a much tighter casserole.

Can You Easily Freeze Your Squash Casserole?

Freezing and reheating is a time-honored tradition when making casseroles. A lot of people believe that casseroles taste their best once they have had a chance to freeze and thaw before eating, so much so that they do not even eat their casserole once it is cooked; they just freeze it!

This squash casserole, however, is not going to be as good if you try to reheat it after freezing it.

This is because the squash has the unpleasant tendency to release even more moisture when freezing, swelling, and shattering as it defrosts and turns mushy and paste-like.

You can, however, prepare the entire casserole and freeze it before you bake it! This lets you prepare it well in advance, giving you the liberty of cooking it for when you want it.

If you do this, make sure not to top it with the Ritz crackers until it is actually time to cook it, or they will turn into a crumbly mess while sitting in the fridge.

If you really must freeze your cooked squash casserole, make sure you wrap it extremely tightly with plastic wrap first. Keep it in the freezer for up to 3 months, and then thaw it in the fridge overnight and bake it at around 300 to 350 Fahrenheit for about 20 minutes, or until heated through.

The texture of the topping definitely won’t be as good as the first time you ate it, but it is a great way to take advantage of leftovers!
