Air Fryer Brussels Sprouts with Balsamic Glaze and Parmesan Recipe
Introduction
Crispy air fryer Brussels sprouts tossed with a savory blend of olive oil, salt, and pepper make for a deliciously easy side dish. Finished with shaved parmesan, a drizzle of balsamic glaze, and toasted walnuts, this recipe offers a perfect balance of flavors and textures.

Ingredients
- 1 lb Brussels sprouts (trimmed, outer leaves removed, and quartered lengthwise)
- 2 tbsp olive oil
- 1/4 tsp salt (or to taste)
- 1/8 tsp pepper
- 2 tbsp parmesan cheese (shaved)
- 2 tsp balsamic glaze
- 3 tbsp walnuts (toasted and salted)
Instructions
- Step 1: In a large bowl, combine the quartered Brussels sprouts with olive oil, salt, and pepper. Toss well to coat all pieces evenly.
- Step 2: Transfer the seasoned Brussels sprouts to the air fryer basket and cook at 360°F for 15 minutes. Shake the basket halfway through cooking to ensure even crisping.
- Step 3: Once cooked, taste and adjust seasoning if needed. Serve immediately, topping with shaved parmesan, a drizzle of balsamic glaze, and toasted walnuts while the sprouts are still hot.
Tips & Variations
- For extra crispiness, soak the trimmed Brussels sprouts in cold water for 10 minutes before drying and cooking.
- Swap walnuts for pecans or pine nuts based on your preference or what you have on hand.
- Add a pinch of red pepper flakes for a subtle spicy kick.
Storage
Store any leftover Brussels sprouts in an airtight container in the refrigerator for up to 3 days. Reheat them in the air fryer or oven to maintain crispness rather than using a microwave.

FAQs
Can I use frozen Brussels sprouts for this recipe?
It’s best to use fresh Brussels sprouts for optimal texture and flavor, but if using frozen, thaw and pat them dry before seasoning and air frying to avoid sogginess.
What if I don’t have a balsamic glaze?
You can make a simple balsamic reduction by simmering balsamic vinegar until it thickens or substitute with a drizzle of honey or maple syrup for a different sweet contrast.
