FAQ
To avoid a watery butternut squash casserole, it is important to remove the moisture from the squash before baking. This only applies if you are using raw butternut squash.
Start by slicing the squash into cubes and adding salt. Let the cubed squash rest on a paper towel-lined baking sheet for about 30 minutes. The salt will draw out some of its water, and you can use the paper towel to dab off any excess moisture before you add it to the casserole.
Yes. Just simply prepare the entire dish up to the point of baking, cover it with aluminum foil or plastic wrap, and refrigerate for up to 24 hours. When ready to bake, remove from refrigerator and bake!

I love how flavorful this was for how easy it was! I made a half recipe with one can of Campbell’s Well Yes Butternut Squash Soup and Target’s andouille chicken sausage, and it turned out great!
This was super delicious and easy to make! I used the Pacific brand of soup and dried thyme. I also added a cup of frozen peas just before adding the cheese for some added veg. I’ll definitely be making this again!
Pacific’s Bnut Squash Soup is THE best.
This was delicious! Great combination of flavors. Also, love how easy it was to make. Will be adding into my dinner rotations.
I’m making this again this week 😀
