The easiest side dish for Thanksgiving! This Baked Mixed Vegetable Casserole is made with a next-level creamy mushroom sauce, fresh veggies, and a crispy cheesy cracker topping that’s SO good. I make this every year for Thanksgiving, Friendsgiving, and tons of holiday get togethers, and it’s always such a fave! This isn’t your ordinary veggie casserole side dish. The flavors and texture are elevated and just phenomenal. I could eat this forever!
