Our Spinach and Kale Gratin is the ultimate winter comfort food and a great addition to any holiday meal.
We loaded up this easy side dish casserole with Tuscan kale and baby spinach that is smothered in a cheesy cream sauce. Then a buttery bread crumb topping is placed on top, and this spinach and kale gratin is baked until hot and bubbly!
Everything – even green veggies – is better smothered in cheese and buttery bread crumbs… Don’t you agree? 🙂
This Spinach and Kale Gratin can be made in advance. Prepare the spinach and kale filling and place in the casserole dish or baking pan – but hold off on adding the crumb topping until right before you bake it. Also – if you’ve refrigerated the filling before baking it – the bake time will be a little longer unless you bring the spinach and kale filling up to room temperature before placing in the oven.
