Want a really fantastic, quick and easy side dish to adorn your Thanksgiving table? This Spinach, Mushrooms & Cheese Casserole has made an appearance on our family’s Thanksgiving table every year. We usually double or triple the recipe because everyone loves it so much, in fact it is the one vegetable dish my kids insists on every year. I’m happy to oblige!
This recipe was told to me by my (ex)mother-in-law. She was a fantastic cook and Thanksgiving meals at her house were always delicious…and very filling. The recipe is very simple and can easily be adjusted to your preferences. If you’re like me, you will sneak in extra mushrooms and cheese! She always used garlic powder, but I use a couple garlic cloves. Either works just fine, whichever you prefer. And the nice thing about this dish is you can make it ahead of time and keep it in the refrigerator until ready to cook. Just take it out of the refrigerator to warm up a bit and pop it in the oven to heat up and get melty good while the turkey rests. It only requires about 20 minutes in the oven.Print
