Tips & Variations
- For extra crispiness, avoid overcrowding the air fryer basket; cook in batches if needed.
- Swap Parmesan for Pecorino Romano for a sharper flavor.
- Add toasted pine nuts or chopped walnuts for a crunchy texture.
- Use smoked paprika instead of red pepper flakes for a smoky twist.
Storage
Store leftover Brussels sprouts in an airtight container in the refrigerator for up to 3 days. Reheat gently in the air fryer or oven to maintain crispness. Avoid microwaving as it can make them soggy.

FAQs
Can I use frozen Brussels sprouts for this recipe?
While fresh Brussels sprouts work best for crispiness, you can use frozen if thawed and patted dry thoroughly to remove excess moisture before cooking.
What if I don’t have a balsamic reduction?
You can make a simple balsamic glaze by simmering balsamic vinegar until it thickens or substitute with a drizzle of lemon juice for a bright finish.
