A Delicious (Different) Dinner Side: Yummy Spinach Casserole

If I go to a nice steakhouse with an a la carte menu, I’m always scanning the side dish options for creamed spinach. It’s not something I typically make at home so it’s always a treat to find it on those rare occasions. And then, a couple years ago, my mom made the most delicious spinach casserole — reminiscent of the flavors of a cheesy creamed spinach, it skyrocketed to my number one request from her. Today, I’m sharing that gem of a recipe! The spinach casserole only requires three main ingredients with a few other add-ins that I always have on hand. It’s special enough to serve to guests, but is also easy enough to prepare for weeknight dinners. Over the past couple of years, this spinach casserole has even been included as a side at our traditional Thanksgiving turkey dinner and Christmas Day prime rib dinners! Perfect for now, or save it for later, read on for this yummy, versatile vegetable side!.
