🔪 How to Make Roasted Balsamic Brussels Sprouts

Add the prosciutto to a lined with parchment paper. Bake for 10 minutes or until crispy.

Allow to drain on paper towels and once it has cooled, crumble it into small pieces.

Increase the temperature to 425°F.

Slice the Brussels sprouts, then add to a baking sheet that’s been sprayed with olive oil. Drizzle the tops with olive oil and sprinkle the garlic salt and pepper over the top.

Toss to combine, then roast in the oven for 35-40 minutes, tossing at least 1-2 times during this time. If there are any leaves that are crispy, remove them and set them aside to add back in later.

Once they are tender and caramelized, remove them from the oven, add the crumbled crispy prosciutto over the top. Drizzle with the balsamic reduction just before serving.

💡 Tips on Making Keto Roasted Brussels Sprouts 

• When you slice the Brussels sprouts, you don’t want them too thin, otherwise they are likely to burn. I have found that for medium size Brussels sprouts, cutting them down the center (from core at the top) in thirds is typically the perfect size. Larger ones, might need to be cut in fourths.
• Try to spread them out in an even layer to allow them to roast and prevent them from steaming instead.
• Taking the time to toss them 2-3 times while they are roasting is a step you don’t want to skip. This will help ensure that they cook evenly and can caramelize properly.
• Keep an eye on the prosciutto, as it can go from crisp to burnt very quickly, since it’s so thinly sliced.
• Don’t overdo it with the balsamic reduction. It has a strong concentrated flavor, so a little goes a long way.

How to Choose Brussels Sprouts

• Before cooking brussels sprouts, trim the woody ends, leaving the sprout itself in place.
• When shopping for brussels sprouts, look for bright green leaves without any browning or yellowing.
• The leaves should be tight and snug against one another.
  For a sweeter flavor, you should look for smaller sprouts as the larger they get, the more they take on a cabbage flavor.
• Avoid packages of Brussels sprouts that have moisture. Brussels sprouts that can not breathe will sweat and create moisture. The moisture will create mold.

Best Cooking Methods for Brussels Sprouts

There are several different ways you can prepare Brussels sprouts for a Keto diet.  Pan frying in bacon grease might be the most popular way and it gives them lots of flavor!  In fact, you can try these Sautéed Brussels Sprouts with Bacon get that that wonderful flavor!

I prefer the sweetness that comes out when you roast them in the oven. They get nice and caramelized, especially when you add the balsamic reduction.

🔄 Substitutions and Additions

• If you don’t have prosciutto, you can use diced pancetta or even bacon instead. Brussels are from the cabbage family, but are slightly more bitter until cooked.
• For a little crunch, you can add some chopped almonds, walnuts, pecans or pine nuts (pignoli).  Just be sure to toast them in a dry pan first, because it really brings out the flavor.
• If you don’t have time to make the balsamic reduction, you can just drizzle a small amount of balsamic vinegar or even just omit it all together.
• For added flavor, you can sprinkle some grated or shaved parmesan, Romano or asiago cheese over the top just before serving. Crumbled goat cheese would also be a great addition.
• For added smokiness, sprinkle about 1 teaspoon of smoked paprika over the tops before tossing the Brussels sprouts and roasting them.
• If you don’t have garlic salt, you can use half garlic powder and half salt instead. Resist the urge to use fresh garlic, which I am almost always in favor of. However since these are roasting at a high temperature, the garlic will burn within seconds and ruin your whole dish.
• For a little kick of heat, you can sprinkle some red pepper flakes over the top. I wouldn’t add more than 1/2-1 teaspoon, as a little goes a long way.

Can You Freeze Brussels Sprouts?

If you have leftovers, you will probably wonder how to freeze brussels sprouts. It’s actually very easy. Just put the leftover Keto Brussels sprouts in an airtight container that’s just big enough to hold them. You don’t want a lot of space left over in the container.

You can also use a freezer safe bag, squeeze out all the air, date the bag of when they were frozen and place them in the freezer for up to a couple of months.
