Cheesy Brussel Sprouts with Bacon

Growing up, I never liked Brussel sprouts. But that’s because we always had them boiled…and well, if you’ve had boiled Brussel sprouts, you get it.

Then I had Brussel sprouts that were not boiled…and it changed my life! They are now one of my favorite vegetables and I love them baked, broiled, roasted, and fried. Basically any way you want to make them, I love them!

These cheey Brussel sprouts are absolutely incredible! They are so rich and delicious that even kids will love them!

Here’s the breakdown: tender brussel sprouts topped with ooey-gooey cheese and crisp bacon, baked in a cast iron skillet.

You won’t believe how good they taste!

Keto Brussel Sprout Bake Ingredients

  • Bacon — cooked and chopped (we cooked it in the same pan first, because the bacon grease adds yummy flavor!)
  • Onion — yellow or white onion, diced
  • Brussel sprouts — remove the outer leaves and cut in half
  • Salt and pepper — to taste
  • Almond milk — or another low carb milk
  • Cornstarch — for thickening
  • Cheddar cheese & Parmesan cheese — shredded (I recommend shredding your own, as pre-shredded cheese often contains additives)

Kitchen Supplies Used:

Can I use regular milk?

Unsweetened almond milk contains 1g carbs per cup, which is why we used it for this recipe. By contrast, whole milk contains 12g carbs per cup.

If you want to keep the carb count as low as possible, I recommend sticking with almond milk, or another keto-friendly milk option such as:

  • Cashew milk
  • Flax milk
  • Macadamia milk
  • Soy milk

Always opt for unsweetened milks and check the labels to be sure!

If you’re not as worried about counting carbs, you’re welcome to use regular milk for this recipe. It will taste just as fabulous!

How to Make Cheesy Baked Brussel Sprouts

<div class=”mv-video-target mv-video-id-xvxrj9dsalict6cb1j7i” data-video-id=”xvxrj9dsalict6cb1j7i” data-volume=”70″ data-ratio=”16:9″ ></div>

Preheat oven to 350°F.

In a cast iron skillet over medium heat, cook the bacon to your desired doneness. Place the cooked bacon on a paper towel-lined plate to cool. When it’s cool enough to handle, crumble into small pieces.

Leave the bacon grease in the pan and add diced onions and halved Brussel sprouts. Cook for about 5 minutes, stirring occasionally, until the onions start to soften and turn clear.

How to Store

If there are leftovers, keep refrigerated in a sealed food storage container. The leftovers can last 2-3 days in the fridge.

How to Reheat

Leftovers can be reheated in the oven or the microwave.

  • In the Oven: If you have time, the oven method will help crisp things up a bit. Simply preheat oven to 350°F and cook until warmed through.
  • In the Microwave: Place leftover Brussel sprout bake in a microwave safe dish and heat until warmed through. Use a microwave cover to keep things neat and tidy.
