In my real life, I tend to not be an appliance-oriented cook. I don't have much storage space, I don't like to learn new (cooking) tricks, and I figure I can just make everything on the stovetop or in the oven.  But I have jumped on the air fryer bandwagon for certain recipes, such as these air fryer Brussels sprouts. It will give you Brussels sprouts closer in texture to restaurant-style Brussels sprouts which are usually deep fried and that's something I simply don't ever do at home. If you're using a convection oven, you may not notice a ton of difference in the crispiness level of air fried Brussels sprouts compared with the results you can achieve in a convection oven. That's because a convection oven is circulating hot oven air around the food, which is what an air fryer also does. It circulates hot air so it acts as a mini convection oven. However, if you are using regular oven, you will see a definite boost in the crispiness level if you use an air fryer instead. If you overcrowd the sprouts on the baking sheet no matter if you have a convection or regular oven, they will be more likely to steam rather than roast. And steaming = mushy in vegetable world! So you will definitely see a positive change if you opt to air fry your Brussels sprouts!
