How do you keep butternut squash casserole from getting watery?

Always sauté the squash and never boil it. Squash already has a lot of natural liquid and boiling it only adds to that, which can make your casserole watery. Sautéing will allow the squash to cook efficiently without adding extra moisture.

Do you peel yellow squash before cooking?

You can, but it is not necessary. Squash skins can be eaten and actually add extra vitamins to your diet. Not to mention it is much easier to leave the skin on. However, always be sure to wash vegetables before putting them in any recipe.

How do you thicken casserole?

There are a few different ways to thicken up a runny casserole. First, you can always add a mixture of corn starch and water. If it’s only slightly runny you may be able to remove the lid of your slow cooker and let moisture escape- just don’t forget about it and let it get too dried out! Another way is to simply drain the mixture. You can even transfer the contents to a skillet or baking pan to cook out the moisture, but be careful not to overcook the squash!

How do you fix a dry casserole?

This can easily be remedied by adding water or broth. You can even add a more creamy substance, such as white sauce or more cream of mushroom soup , depending on the flavor and texture you desire.

Variations for squash bake

Add zucchini– For extra color and flavor.

Try different cheeses– To match your own flavor pallette, such as mozzarella, gouda, or provolone.

Use other squash– There are many different squash types out there to choose from, including spaghetti squash and butternut.

Try different soups– If you don’t enjoy cream of mushroom soup, you may also switch it up. I would recommend cream of chicken, but you could also use others, like cream of celery or cream of broccoli.

Use herb flavored bread crumbs- The best option is to crush herb stuffing into crumbs. Only add Italian seasoning if using plain bread crumbs

Make topping crispy and crunchy– By broiling in the oven for about five minutes with the lid off and watching the top turn golden brown.

Tips and Techniques for Summer squash casserole without eggs

  • Don’t boil the squash- Because that will make a runny, watery, mushy casserole since the squash will retain too much liquid.
  • Use Italian seasoning– ONLY if using plain bread crumbs. Otherwise there will be too much herb flavor.
  • Use fresh squash– Because frozen squash can lead to a more mushy casserole with too much liquid.
  • Always wash squash– Before preparing your dish and cooking, because it helps prevent food poisoning and other problems.
  • Use unsalted butter– Otherwise your casserole might be too salty.
  • Use full fat– Cheeses and soups in order to bring out the richest flavor.

Storage

Refrigerator– Leftovers can be stored in a sealed container in the fridge for up to 3 days and reheated in the microwave but the topping won’t be as crispy any more. 

Freezer- This is not recommended, because the squash will become mushy, the dairy will separate, and the topping will be soggy.
