Low Carb Brussel Sprouts Casserole with Bacon

When I was a kid my thoughts about Brussels sprouts conjured up all sorts of disgusting and bitter memories of the boiled Brussel sprouts. I couldn’t ever understand why my mom even cooked them. 

The days of yucky, boiled, and bitter Brussel sprouts of the past are long gone! Thanks to farmers making them less bitter, and learning how to properly roast and carmelize this savory vegetable, we have taken this little green sprout from the bottom of the barrel to a family favorite vegetable!

While this keto Brussel sprouts casserole can be served as a complete meal since it includes protein, dairy, and vegetables, you may also want to try pairing it with a simple side salad or some additional fatty-protein options including bratwurst or ham.

No matter how you serve them, Brussel sprouts are always a great choice! If you’re looking for more low carb Brussel sprouts recipe, be sure to try our oven roasted Brussel sprouts and our maple roasted butternut squash and Brussel sprouts.

Ingredient Notes

Clean Brussel sprouts, fresh bacon, your favorite block of white cheese, and some heavy cream are about to combine to show you just how flavorful and wonderful a keto Brussel sprout casserole can be.

• Brussel sprouts
• heavy whipping cream
• white cheese – shredded (we used a swiss/gruyere blend)
• black pepper
• sea salt
• bacon slices – easily cook your bacon in the oven or try air fryer bacon

Variations

Mixing in other hearty vegetables like cauliflower or broccoli works great too!

Diet Adaptions

While we know that our keto Brussel sprouts casserole is low-carb and keto-friendly, we do want to caution you against using pre-shredded cheese. Pre shredded cheese often has a coating of potato starch (to prevent sticking) that adds unwanted carbs to your dish. Whenever possible we always recommend using block cheese and shredding it yourself. Not only do you limit the hidden carbs, but you do also get a better-tasting cheese.

Step By Step Instructions

To key to making the perfect keto Brussel sprouts casserole is taking your time and being patient. Allow the sprouts to bake and caramelize before you add the cream and cheese that will finish off your dish.

Your patience will be rewarded!

Prep

Preheat your oven to 400F. Make sure your oven rack is in the middle position.

Grease a 2-quart baking dish with oil or cooking spray. Either a 9×9 baking dish or a small casserole dish will work.

Cut the Brussel sprouts in half and lay them cut side down in the prepared baking dish.

Assemble

Bake your Brussel sprouts in the oven for 30 minutes. (***Note: This will not fully cook your Brussel sprouts.)

While the Brussel sprouts are baking, cook your bacon on the stovetop (alternatively, you can use pre-cooked bacon and skip this step). Crumble the bacon.

After your Brussel sprouts have cooked for 20-minutes, begin preparing the cheese sauce.

In a grease skilled, over medium-low heat, combine the heavy whipping cream, shredded cheese, salt, and pepper. Heat the sauce until the cheese is melted.

Bake

After the Brussel sprouts have baked for 30-minutes, remove them from the oven.

Sprinkle the cooked bacon on top of the Brussel sprouts and top with the cheese sauce. Feel free to add a small sprinkle of additional cheese directly to the top.

Place the casserole back into the oven and bake for an additional 10-15 minutes, until the entire dish is bubbly and the cheese is lightly browned.

To check for doneness, pierce a Brussel sprout with a fork to make sure it’s tender.

Serve the Brussel sprouts keto recipe warm and enjoy!

Recipe Tips

• If you have more Brussel sprouts than can fit in a single layer it is OK to double them up. Just make sure all of your sprouts are cut side down.
• Placing the Brussel sprouts cut side down will allow the insides to receive direct heat and cook more evenly.
• Start the cheese sauce in the last 10-minutes that the Brussel sprouts are baking to prevent the sauce from cooling too much and hardening.
• Be sure to cook your Brussel sprouts for a full 30-minutes prior to adding the bacon and cheese sauce. This will help the sprouts to carmelize and soften and give you a keto Brussel sprouts casserole that is sweet and savory.
• While we prefer a mix of swiss and gruyere, you can use any white cheese that your family loves.
