These are the cheesiest, most tender Brussels sprouts you will ever eat! Au gratin Brussels sprouts are the ultimate veggie side dish.
What Is Au Gratin
This is a French word that describes any dish that is sprinkled with bread crumbs or grated cheese and then browned. It’s usually baked, but I’ve seen au gratin recipes made in the air fryer or even on the stove and then broiled.
The most popular type of food to serve au gratin is potatoes. I took my favorite au gratin potatoes recipe and turned it into something deliciously low-carb. I just replaced the potatoes with Brussels sprouts.
If you’re nervous, don’t be! It’s really easy and turns out tasty, I promise!
Au Gratin Brussels Sprouts
I love cheesy recipes, don’t you? If you’re a huge fan of the combination of parmesan and gruyere cheese, then you’ll love this Brussels sprouts recipe!
If you want them to have a more authentically crispy coating, sprinkle some pork rind crumbs on top. I used bacon pieces. They are perfectly crispy with the right balance of saltiness too.
You can also make au gratin recipes with cabbage. My cabbage au gratin is super popular because that cheesy sauce is unbeatable.
Brussels Sprouts Side Dish
Brussels sprouts are wonderfully low in carbs and high in fiber. They are full of antioxidants, making them nutritious and helpful at preventing disease.
There are a lot of different ways to cook them too. For this au gratin recipe, I just sliced them in have and cooked them with the other ingredients. It’s pretty effortless.
You can also make Keto Brussel Sprouts Casserole by combining a bunch of tasty and healthy ingredients together and backing it.
If you like the crispiness of oven-roasting, make some Roasted Cauliflower & Brussel Sprouts with Bacon. The bacon makes it extra-crispy and they have smoky undertones.
Or skip both the stove and the oven and make Air Fryer Crispy Keto Parmesan Brussel Sprouts. The parmesan cheese crisps up so well in the air fryer.
Best Cheese For Au Gratin
Honestly, any kind of cheese will work with your au gratin recipes. I prefer to add heavy whipping cream to parmesan and gruyere cheese. It comes out earthy and slightly sweet. You can mix in some mozzarella cheese too if you want.
What To Eat With Brussels Sprouts
This is a simple side dish that goes with any entree you want to make. Serve it with Low-Carb Garlic Butter Roast Chicken. The chicken is made with fresh herbs and the best combination of garlic and butter.
If you prefer beef, make a cheesy Keto Philly Cheesesteak Casserole. The peppers are crisp-tender and so good for you.
