Crispy Roasted Brussels Sprouts

This post may contain affiliate links. Read my full disclosure here.

The key to getting a good char on roasted Brussels sprouts is baking them in a single flat layer, and making sure they don’t overlap. This is a great recipe to show how to do that without using any oil.

Confession of former Brussels sprouts hater

When I was growing up, the only way I ever tried Brussels sprouts were boiled, and I never cared for them. My sister felt the same way. She actually said she hated them and, truthfully, we both pretty much did.

My sister used to be known in our house as The Vegetable Hater. She went through a conversion in her forties and adopted a plant-based lifestyle. No kidding! You can read about her success in the link above. If she did it, anyone can.

The best way to cook Brussels sprouts

Roasting brings out the best in Brussels sprouts. The high temperature gives them a crisp golden outside while keeping them tender inside. They can even be made in an air fryer, so you don’t have to heat up the kitchen.

Most of the time, I buy fresh Brussels sprouts from the store but even frozen ones can be used here if that’s what you have on hand.

Always wash fresh Brussels sprouts with warm water to remove any grit and germs. I like to toss them into a colander and rinse them under warm water.

Do you need to slice them in half?

The first thing to do is to decide whether you want to slice the sprouts in half or roast them whole. To determine this, I always consider their size and that can vary at different times during the year.

If they are large, I will cut them in half and, if they are on the smaller side, I usually always keep them whole.

I am often asked what knives I use and recommend for cooking, and my favorite brand is Victorinox Swiss Army Cutlery. Yes, that’s the same company that makes the Swiss Army Knife. These knives come with a lifetime guarantee and are very reasonably priced. I absolutely love mine.

I like to place the sprouts on a baking sheet covered with parchment paper for oil-free baking. It also makes clean-up a breeze, because the baking sheet only needs to be wiped and put away.

Just make sure that the sprouts are in a single layer and not overlapped, so they can cook well and have a chance to get nice and crispy.

Other options for cooking them are roasting in a cast iron pan or cooking them in an air fryer.

Next, I like to mist the sprouts with lime juice and then sprinkle with salt, pepper, and garlic powder. Some folks prefer to use lemon juice or balsamic vinegar. Any of these will work well.

Another great option is to drizzle them with a little maple syrup to give them a deep sweet flavor.

How long to cook them

Bake at 400°F for about 30 minutes–depending on their size. If you decide to slice them in half or quarters, the cooking time can be reduced to about 20 minutes.

If you’re using an air fryer, cook them at 360°F for approximately 12 minutes.

Whichever cooking method you use, keep an eye on them near the end of the cooking cycle to make sure they don’t burn.

Tips for roasting Brussels sprouts

  • I prefer fresh Brussels sprouts but frozen can also be used.
  • Make sure to wash fresh sprouts thoroughly to remove grit and germs.
  • Baking time will vary depending on the size of the sprouts and whether you slice them in half or not.
  • Mist with lime juice, lemon juice, or balsamic vinegar to add to the flavor and help spices to stick.
  • Salt, garlic powder, onion powder, and smoked paprika are all great spices to use.
