This smoky roasted Brussels sprouts and bacon recipe is so dang easy to make and it’s been a fan favorite since the dish debuted on this blog way back in 2010. For a long time, I couldn’t figure out why; after all, Brussels sprouts aren’t exactly everyone’s favorite vegetable. Personally, when I was a kid, I couldn’t stand ’em.

Better with Bacon!

It wasn’t until adulthood that I discovered that the mild, nutty bitterness of these bulbous sprouts blends beautifully with smoky pork. It was the warm Brussels sprouts salad with bacon and eggs at the now-long-gone Gordon’s House of Fine Eats in San Francisco that first opened my eyes and ultimately inspired the Cavolini Al Forno recipe in my first cookbook. But with ingredients like Brussels sprouts and bacon, you don’t have to spend much time in the kitchen to produce a flavorful side dish that punches you in the face with flavor.

Can you make it in an air fryer?

Yes! The air fryer browns the Brussels sprouts and bacon bits beautifully and the cooking time is cut in half. However, the main disadvantage of using an air fryer is that most models have a small cooking capacity so you will need to cook this recipe in two batches.

How to store leftovers

If you happen to have leftovers, you can store them in a sealed container for up to four days. You can use the leftovers as the base for a fantastic scramble or frittata. Or simply heat up the Brussels sprouts and bacon in a skillet and top everything with a fried egg!

Cooking in an air fryer?

Place half the seasoned Brussels sprouts and bacon in your air fryer basket. Air fry at 400°F for 12 to 15 minutes, tossing the contents at the halfway point. The dish is ready when the sprouts and bacon are nicely browned and there are crispy bits. Repeat the same steps with the remaining sprouts and bacon.
