In a large bowl, combine the halved Brussels sprouts, mushrooms, and cherry tomatoes.
Drizzle with olive oil and lime juice.
Sprinkle the dried rosemary, salt, and black pepper over the vegetables and toss thoroughly until everything is evenly coated.
Transfer the seasoned vegetables to your air fryer basket.
Arrange them in a single layer to ensure they roast evenly—work in batches if necessary.
Air fry at 380°F (190°C) for 20 minutes.
Be sure to shake the basket at the 10-minute mark to toss the vegetables for even crisping.
Serve immediately while hot and enjoy!
Don't overcrowd the basket. For the crispiest results, keep veggies in a single layer so they roast instead of steam.
Cook in batches if you need to.
Pat your vegetables completely dry after washing. Any excess moisture will prevent them from getting that perfect golden-brown char.
Finish with a fresh squeeze of lime right before serving. This simple step makes all the earthy, roasted flavors pop.
