This Chicken Spinach and Mushroom Low Carb Oven Dish quickly became one of those meals for me. Some dishes just become a part of your comfort routine after the first mouthful.

I was genuinely worn out last weekend. It had been one of those exhausting weeks when work, errands, accumulating laundry, and figuring out what to cook every night seemed to go on forever. I didn’t want the heavy feeling that comes with takeaway or meals high in carbohydrates, but I did want something cozy and warm.

At that point, my sister, who had just tasted this creamy chicken spinach mushroom bake, suggested it. “You have to make this,” she insisted. It feels nutritious even if it tastes like comfort food. And she was entirely correct..
