Brussels Sprouts are baked in a creamy cheese sauce with bacon is a delicious vegetable side dish that will get the non-Brussels-eaters digging in at your holiday table.

Brussels sprouts covered in a bacon cheese sauce

If you’re looking for a healthy holiday side dish, this Brussels Sprouts and Bacon Gratin is not the one for you. I do have a healthy Roasted Brussels Sprouts with Cranberry Glaze recipe that might be right up your alley.

This is an old recipe that I just updated images and video from 2015 that is always a hit. I usually simply roast Brussels sprouts, but for the naysayers, this method will convince them. Who doesn’t love bacon and cheese?

We all know everything is better with bacon, and this truly is the best example of that. This recipe is keto and low carb. To make it gluten-free, use gluten-free flour. All the dietary bases are covered (meat-free option below) so there’s no excuse not to make it.

What is ‘au gratin’?

Au gratin is a French term that simply means to gratiné (plural) top a dish with cheese (sometimes along with breadcrumbs) and browning in the oven. I also have a very tasty Butternut Squash and Sage Gratin that you need to check out.  < Just click on the name for the link. 

Meat-free options:

You can omit the bacon and served with my new recipe for Vegetarian Mushroom Wellington with Gravy (pic above) and your veggie holiday meal is done!
