Using a medium or large bowl, place the halved Brussels sprouts into the bowl, then add the olive oil, balsamic vinegar, salt, and pepper and toss to coat. Work through this step deliberately rather than rushing it, because this is where the texture and balance of the recipe start to take shape. Keep the listed quantities and order of operations unchanged, and have the next ingredients ready before you move on.

Using an Air Fryer, spread the Brussels sprouts into the basket, then close and turn the air fryer to 400 degrees and set timer to 5 minutes. Work through this step deliberately rather than rushing it, because this is where the texture and balance of the recipe start to take shape. Keep the listed quantities and order of operations unchanged, and have the next ingredients ready before you move on.

Once the timer beeps, open the air fryer and carefully mix the Brussels sprouts around. Work through this step deliberately rather than rushing it, because this is where the texture and balance of the recipe start to take shape. Keep the listed quantities and order of operations unchanged, and have the next ingredients ready before you move on. Mix until the ingredients look evenly combined, but do not overwork them unless the original method specifically says to.

Scrape the sides and bottom of the bowl so no pockets of seasoning, flour, sauce, or unmixed ingredients remain. The mixture should look cohesive before you continue.

Spread them in an even layer, then sprinkle the breadcrumbs and cheese over the tops (some might fall down into the cracks, that's okay). Work through this step deliberately rather than rushing it, because this is where the texture and balance of the recipe start to take shape. Keep the listed quantities and order of operations unchanged, and have the next ingredients ready before you move on.

Close the Air Fryer and set for 5 more minutes at 400 degrees. Work through this step deliberately rather than rushing it, because this is where the texture and balance of the recipe start to take shape. Keep the listed quantities and order of operations unchanged, and have the next ingredients ready before you move on. Pay attention to the sensory cues in the food: aroma, color, softness, thickness, and how easily the ingredients move when stirred or handled.

These signs are usually more reliable than timing alone. The biggest mistake is moving ahead before this step looks complete.
