A couple of weeks ago we went on a bike ride to the next beach town over and had lunch. When restaurants have Brussel sprouts as a side item, I am always interested in different ways to make these yummy sprouts. That day I ordered brussels sprouts grain! They were heavenly! 

Baked Brussels Sprouts Casserole

The sprouts were roasted first and then added to a cheesy bath and baked in a casserole dish. Super easy right? There are tons of ways to make this casserole. I took the super easy 4 ingredient way! No roasting, just microwave the sprouts and make a simple roux, pour it over and bake!

Of course, you can always roast them first. See my Roasted Brussels Sprouts post for the recipe or keep scrolling. Here is our simple Brussels sprouts gratin recipe! Enjoy!
