This Brussels Sprouts au Gratin recipe is low carb at its best — creamy, rich, and just a little bit smokey from bacon and a little kick of chipotle. You can even assemble it up to two days ahead of time and bake it just before serving.
Honestly, when you think about it, the low carb lifestyle is great during the holidays. If you are low fat or low calorie you have to give up all of the rich sauces, gooey and cheesy dishes, and buttery yumminess that low carb allows. I this side dish for Thanksgiving and everyone (except the Brussels Sprouts haters) loved it and didn’t realize it was low carb until I said something. Even then they didn’t care they just went back for more.
Fresh Brussels sprouts are cooked, drained, tossed with bacon then covered with a gooey, creamy cheese sauce that has been infused with chipotle and guajillo chiles. Bake it for 30 minutes and it’s ready to go.
If you are not familiar with guajillo chiles you should be. They are a dried chile pepper with a mild heat and a fruity flavor. Think of raisins with a kick. They add depth and complexity to almost anything you put them in. The chipotle adds smokiness and just a little more heat but nothing that you can’t handle. It’s all wrapped up and balanced by the cheese sauce.
This sauce is made by simmering the chiles in the cream while it reduces. When you take the chiles out the flavor remains. Just whisk in the cream cheese and add grated cheddar, stirring until smooth. Taste it and add a pinch of chipotle powder if you want more heat. That’s it. It just doesn’t get easier than that.
You can also assemble this Brussels sprouts au gratin recipe a day ahead of time. Just cover it and refrigerate until just before you are ready to bake it. I suppose you could microwave the dish if you need to but it does tend to cause the sauce to break and become oily.
