I haven’t always been a fan of spinach—especially cooked—but that’s changed with time. While I still won’t go near plain cooked spinach on its own, this Keto and Low-Carb Spinach Casserole completely won me over. Creamy, flavorful, and topped with a satisfying crunch, it’s the perfect side dish for just about any meal. Even spinach skeptics might be surprised by how much they enjoy it—I certainly was!
