This is an easy, weeknight gratin with cannellini beans, spinach, Parmesan and bacon. It's not as rich as other gratins because it doesn't have a cream sauce but instead relies on Parmesan cheese and a small amount of mashed-up beans to help thicken it.

Add the broth, all the beans but ½ cup and the spinach, bring to a simmer and cook about 5 minutes until the spinach is wilted. Mash up the ½ cup beans with a fork and mix them in too.
Remove from heat, mix in the basil and ½ cup of the Parmesan.
Pour into the casserole pan and sprinkle the remaining Parmesan over top. Bake 20 minutes. Sprinkle the bacon over top and serve with additional Parmesan cheese.
