This Spinach and Butternut Squash Casserole is a delicious make-ahead recipe that feeds a hungry crowd. It freezes beautifully too so don't be afraid of leftovers.

*Disclaimer - This recipe was originally published in 2014. I'm working hard to update all my older recipes with recipe cards, new photos, and additional recipe information. But, getting to all of them will take time. Please bear with me. In the meantime let me assure you that this recipe is still a winner and one I'm sure you'll be well pleased with when you make it at home.

I decided to adapt and update a recipe found on page 79 of a cookbook called "Old Time Brand Name Cookbook." This recipe takes advantage of frozen vegetables (which makes sense coming from Birds Eye) so I decided to kick it up a notch by adding in some frozen butternut squash chunks (along with the called for frozen spinach), a bit of freshly grated nutmeg and then tossed the egg noodles with some pumpkin oil and butter before adding it to the casserole dish for baking.
Can I tell you something? My husband, who's not a big fan of butternut squash, LOVED this casserole and was a happy camper each and every time I served this casserole as a leftover too. Now that's a wonderful thing! *Note - when reheating, make sure to cover the dish so the noodles don't dry out. If needed, add a ¼ cup of water to keep it creamy and delicious.
To keep things simple (circa the 1950s), this casserole can be made in advance and refrigerated until you're ready to bake. Just remember to bring it to room temperature before baking so the bake time isn't altered. *Note - If the casserole is still cold, the baking time needs to be increased.

Such a comforting casserole! I would just spoon it from the dish. HOT. Then it will be all gone. And my family will be mad at me. But my belly would be full, so I won't care for a bit.

I hide butternut squash in mac & cheese with good success. (Read: my boys never know the difference.) Your pasta looks like something they'd devour without complaint!
