Sausage and butternut squash casserole for a quick weeknight dinner. It’s perfect for leftovers as well.

 Sausage and butternut squash casserole

Six days in for the month of October and I have 7 mosquito bites.


It’s supposed to be cool weather, leaves turning colors, pumpkins lining the driveways and everyone outside enjoying the fall season. Instead I’m hiding indoors knowing that I can’t get away from these bloodsuckers.

The other night my husband and daughter were outside playing in the “somewhat” cooler air while I was avoiding the outdoors at all cost. I remembered that I had bought a butternut squash and it was lying on the counter just waiting for me to cut it up. Now I will be honest with you about cutting these things up. I would rather just buy butternut squash already cut into cubes than cut it up myself. Yes, it may be more expensive but it’s a royal pain.

Knife in hand, I started to chip away at the skin until I had several cups of nicely chopped butternut squash. I knew that instead of my usual roasting technique that I wanted to place them in a casserole recipe. Next it was time to see what was in my refrigerator that could possibly pair well with the squash. Link sausage and spinach were my go-to items and at the last minute I decided to add the egg mixture for a little more depth to the casserole.

In hindsight this casserole was easy to make and it kept me from getting bit outside.
