If I were to confess some of my guilty pleasures in life, then these brussels sprouts gratin photographs would convey much of what I’m already about to say. Warm melted cheese, gooey-salty-decadent-calorie-laden cheese on top of perfectly fresh and healthy vegetables should be illegal. I think of this often when a gorgeous bowl of green veggies gaze back at me with fresh, vibrant eyes. Instead of reaching for the steamer and ideas of a raw salad, I reach for the rind of parmesan cheese, cream and block of butter.Cheesy Brussels Sprouts Gratin Recipe | Brussels Sprouts Casserole (1)

A Family Favorite Brussels Sprouts Gratin Recipe

Over 98.6572% of the time I prepare my vegetables very simply in a light saute or raw, crunchy salad. This is how I appreciate my vegetables the most and sums up the way I ate as a vegetarian for almost twenty years. But when the air begins to crisp up to cooler embrace, I sense that Fall is near. That’s when I’m guilty of killing my vegetables in a casserole pool of cheese and cream.Knowing when to stop eating is something I’m still lacking at. My mind tells me that if the food is delicious, eat another plate before it goes to waste.

A Cheesy Brussels Sprouts Treat for the Holidays

Balance is something I’ve always been thoughtful of and with all the travel we’ve been on, I realize that I’ve ignored the gym more than I should. Perhaps it’s the lack of fitness and exercise that makes eating two portions of food laden with guilt. I’m putting exercise back on my priority list before the holiday season feasting begins.Thankfully I don’t eat my vegetables like this every day, but when I do, I really appreciate every bite of dreamy, rich decadence. And then I always try to remember that there’s vegetable hidden somewhere in all this cheesy mess.

My goal for the next few months is to get back on cardio track again so that I can enjoy more of these warm, cheesy casseroles. This recipe for Brussels sprouts gratin is one of my favorite Brussels sprouts dishes for the fall because there’s comfort in every bite. Guaranteed this will be at on our Thanksgiving menu because it’s so simple, wonderful and a pleasure to eat.
