Keto Brussels Sprouts
Truth is, I used to despise Brussels sprouts when I thought that the only way to cook was by steaming them in the microwave!
Then, I realized how amazing these little mini cabbages could taste when they were roasted or air-fried. I have several Brussels sprout recipes, like Keto Brussels Sprout Broccoli Salad with Cranberries, Healthy Crunchy Roasted Brussels Sprout Salad, Keto Caramelized Skillet-Roasted Brussels Sprouts as well as many more.
This Keto Cheesy Brussels Sprouts Casserole was an easy keto side dish that I adapted from Delish. By swapping out a few ingredients, this recipe quickly became one of our favourites!
Why you should eat more Brussels sprouts
Brussels sprouts, often met with mixed reactions at the dinner table, are miniature powerhouses of nutrition that deserve a place on your plate. Packed with vitamins, minerals, and numerous health benefits, these tiny cruciferous vegetables are much more than just a side dish. Let's delve into the reasons why Brussels sprouts should be celebrated for their contribution to a healthy lifestyle.
- Rich in Nutrients: Brussels sprouts are a nutritional goldmine. They are an excellent source of vitamin C, vitamin K, and vitamin A. Additionally, they provide essential minerals such as potassium, manganese, and folate. These nutrients play vital roles in supporting immune function, bone health, and overall well-being.
- Cancer-Fighting Compounds: Brussels sprouts belong to the cruciferous vegetable family, which is known for its cancer-fighting properties. These veggies contain glucosinolates, compounds that have been linked to a reduced risk of certain cancers. The sulfur-containing compounds formed during the breakdown of glucosinolates have been shown to have protective effects against cancer.
- Rich in Fiber: Fiber is crucial for a healthy digestive system, and Brussels sprouts are an excellent source. High fiber content helps regulate bowel movements, promotes a feeling of fullness, and supports gut health. Including Brussels sprouts in your diet can contribute to a well-functioning digestive system.
- Antioxidant Powerhouse: Brussels sprouts are loaded with antioxidants, including flavonoids, polyphenols, and carotenoids. Antioxidants help combat oxidative stress in the body, reducing inflammation and protecting cells from damage. This can contribute to a lower risk of chronic diseases and support overall health.
- Heart Health: The combination of fiber, antioxidants, and anti-inflammatory properties in Brussels sprouts makes them a heart-healthy choice. These elements work together to lower cholesterol levels, regulate blood pressure, and promote cardiovascular well-being.
- Weight Management: Brussels sprouts are low in calories and high in fiber, making them an excellent choice for those looking to manage their weight. The fiber content helps keep you feeling full, reducing the likelihood of overeating and aiding in weight control.
Keto Cheesy Brussels Sprouts Casserole Ingredients
You only need some basic ingredients and about 30 minutes of time to make these keto Brussels sprouts!
- Brussels Sprouts - You will need 1 pound of Brussels sprouts. To prepare the Brussels sprouts, you will need to cut the bottom part of the stem that is brown and then slice each sprout in half, lengthwise.
- Bacon - You will need 4 slices of bacon but feel free to use more if you wish (I chose 4 slices since it is what I had left after making this Keto Bacon-Wrapped Pork Extravaganza)
- Shallots - You will need 2 small shallots. If you do not have any shallots, you can use a different type of onion. Just remember that shallots have a little more flavour as well as a hint of garlic you may want to add some additional garlic spice if you choose to use a plain onion.
- Mushrooms - The original recipe only called for Brussels sprouts but since I had a package of baby portabella mushrooms, I decided to add it. If you do not have any mushrooms, you can replace the mushrooms with an additional pound of Brussels sprouts.
- Cream - I have made this recipe with either half and half or heavy cream. Do not substitute almond milk or regular milk as the sauce will be too watered down.
- Cheese - A combination of sharp white cheddar and shredded Gruyere cheese adds a nice complexity to this dish. You can use any cheese you choose but I HIGHLY recommend sticking to the cheese in the recipe card.
- Spices - Salt, black pepper, and some cayenne help to elevate the dish.
Keto Holiday Side Dish Instructions
This easy keto side dish is so simple that you won't be saving it for special occasions!
In a large oven-safe skillet over medium heat, cook bacon until crispy, 8 minutes. Drain on a paper towel-lined plate, then chop. Add the diced onion, Brussels sprouts, and mushrooms to the skillet with the leftover bacon grease. Cook on medium-high heat until the Brussels sprouts are fork tender, about 10 minutes.
In a small bowl, heat the cream (or half and half) with half of each cheese until the cheese melts, about 1-2 minutes, stirring every 30 seconds. Add the bacon to the skillet with the vegetables and toss with the heavy cream mixture.
In a small bowl, heat the cream (or half and half) with half of each cheese until the cheese melts, about 1-2 minutes, stirring every 30 seconds. Add the bacon to the skillet with the vegetables and toss with the heavy cream mixture. Sprinkle with remaining cheese.
Bake in a 375-degree preheated oven for 12-15 minutes or until the cheese begins to brown.
Are Brussels sprouts keto-friendly?
Yes! Not only are Brussels sprouts packed with vitamins, minerals, and anti-oxidants but they only have about 4 grams of net carbs per cup.
Can I make these creamy Brussels sprouts dairy-free?
Yes. Use coconut milk (from a can) and dairy-free cheese instead of cream and dairy milk.
Can I make this into a plant-based keto side dish?
Yes. Simply omit the bacon and use butter to saute your vegetables. You may want to add additional salt to compensate for the lack of salt that comes from the bacon.
How do I store this Brussels sprouts casserole?
Store any leftovers in an airtight container for up to 3 days.
