The creamy, cheesy top hits the spot, perfectly suited to cooking in tiny batches. I made this casserole for the first time on a cold evening when I wanted something hearty but didn’t want to spend hours cooking. The next day, leftovers were served over breakfast, and everyone in the family loved it so much.

Creamy Brussels Sprouts Casserole Recipe

This creamy Brussels sprouts casserole recipe is simple yet delicious. It combines tender Brussels sprouts with a rich, cheesy sauce that makes every bite irresistible. Perfect for a weeknight dinner, this dish can be made in small portions for those of us who love cooking for just one or two people. 

This is flexible enough to serve as a side dish or a comforting main meal just like this pork fillet recipe and walking taco casserole. The creamy sauce pairs wonderfully with the slightly crispy sprouts, making it a perfect option even for picky eaters. Best of all, it comes together quickly with just a few basic ingredients.

Best Casserole Ingredients to use for Cheesy Brussels Sprout

Choosing the right ingredients is key to making this casserole creamy and flavorful. Brussels sprouts are, of course, the star of the dish, but the real magic happens with the creamy sauce.

Using a good quality grated cheese, such as sharp cheddar or gruyère, adds a deep, savory flavor that pairs perfectly with the slight bitterness of the sprouts. For extra creaminess, I like to add a dollop of sour cream, which blends beautifully with the eggs and cheese to create that luscious, thick sauce.

Easy Brussel Sprouts Gratin

You might think Brussels sprouts aren’t the most exciting veggie, but once you’ve tried them in this gratin-style casserole, they’ll win you over. The key is boiling the sprouts before adding them to the creamy sauce—this brings out their natural sweetness and adds a bit of texture.

In this version of a brussels sprouts gratin, you don’t need fancy ingredients or tons of time. It’s a quick and straightforward recipe that can be made with ingredients you probably already have in your pantry, making it perfect for those last-minute dinners.

Must-Have Tools for Your Kitchen
