Parmesan Roasted Brussels Sprouts

Brussels sprouts have come a long way when it comes to recipes and the flavor of the vegetable. In fact, I have been on a Brussels sprouts kick, sprouting (get it?!?) lots of recipes for this now popular vegetable. If you are now a fan, be sure to try other variations like Bacon Wrapped, Shredded, Brown Butter, Balsamic Roasted, and Brussels Sprouts in Maple Bourbon Sauce, just to name a few!

How to Prepare Brussel Sprouts

Roasting Brussels Sprouts

Roasting vegetables is quite possibly my favorite way to eat them. A beautiful caramelization of natural sugars combined with oil and a light seasoning transforms vegetables into something magical. But what is “roasting” exactly? Back in the day roasting meant there was going to be an open flame. Today, we roast things in an oven. (I will also let you know how to make these in an air fryer.)

When roasting Brussels sprouts, I take a couple of things into consideration:

  • Size– If they happen to be large, I will cut them in half before roasting. If they are smaller, like the ones we harvested from our garden, I will roast them whole. (These are also the best tasting in my opinion!)
  • Freshness– They should be green, not yellow, with no black spots. They should also be very firm. If you can find Brussels sprouts still attached to the stem they will last much longer if stored in a cool, dry place.

Air Fryer Brussels Sprouts

I love using my air fryer for Brussels sprouts; it makes them nice and crispy! To make the Parmesan Roasted Brussels Sprouts in an air fryer, follow the instructions up to placing the vegetable in a baking dish. Instead, place the coated Brussels sprouts into the basket of your air fryer, avoiding overlapping. Air fry at 375°F for 10-15 minutes, shaking the basket halfway through. Depending on your desired crispness, you may need to adjust the cooking time.

What to Serve with Roasted Brussels Sprouts?

Can I tell you a secret? I have made a pan of these and ate them all by themselves. But just in case you are normal and like well-rounded meals, here are a few great options.

How to Store

Cooked Brussels sprouts can be stored in an airtight container in the refrigerator. They will last up to 4 days or so. Reheat them in the oven or air fryer.

  1. Very tasty. I used frozen sprouts; defrosted them in the microwave, and then split them, proceeding likewise from the recipe. I found that leaving them in the oven after roasting for about ten minutes as the oven cooled burned off a lot of the excess moisture and gave them at least a little brown tinge.
