An overhead shot of golden-brown Brussels sprouts with charred, crispy edges piled in a rustic ceramic serving bowl. The sprouts glisten with a drizzle of dark balsamic glaze, creating striking contrast against their caramelized exteriors. Scattered sea salt flakes and freshly cracked black pepper are visible atop the vegetables. A wooden serving spoon rests alongside, and a few fresh thyme sprigs provide a pop of green. The warm, directional light highlights the textural differences between the crispy outer leaves and tender centers, while a fabric napkin in muted blue provides soft background texture.

Directions

<ol class="no-list-style"> <li class="MethodStepper"> <h4 class="step-title">Step 1</h4> Trim the Brussels sprouts by cutting off the tough stem ends and removing any yellowed or damaged outer leaves. Cut each sprout in half lengthwise through the stem. This creates more surface area for caramelization, which is key for developing flavor. </li> <li class="MethodStepper"> <h4 class="step-title">Step 2</h4> Place the halved Brussels sprouts in a large mixing bowl. Drizzle with olive oil, add minced garlic, salt, and pepper. Toss thoroughly to ensure each sprout is evenly coated. The oil is essential not just for flavor but for conducting heat evenly across the surface of the vegetables. </li> <li class="MethodStepper"> <h4 class="step-title">Step 3</h4> Preheat your air fryer to 180°C for 3 minutes. This step is important as starting with a hot air fryer promotes immediate browning and prevents soggy vegetables. </li> <li class="MethodStepper"> <h4 class="step-title">Step 4</h4> Transfer the seasoned Brussels sprouts to your air fryer basket, arranging them cut-side down in a single layer. Don't overcrowd the basket - work in batches if necessary, as overcrowding will create steam and prevent proper crisping. </li> <li class="MethodStepper"> <h4 class="step-title">Step 5</h4> Air fry the Brussels sprouts at 180°C for 8 minutes, then shake the basket to redistribute them. Continue cooking for another 3-5 minutes until they're deep golden brown with crispy edges and tender centers. You'll know they're done when you can easily pierce them with a fork but they still maintain some structure. </li> <li class="MethodStepper"> <h4 class="step-title">Step 6</h4> If using store-bought balsamic glaze, warm it slightly. If making your own, pour balsamic vinegar into a small saucepan and simmer over medium heat until reduced by half and thick enough to coat the back of a spoon (about 5-7 minutes). The natural sugars in the vinegar will caramelize, creating a sweet-tart flavor that beautifully complements the sprouts. </li> <li class="MethodStepper"> <h4 class="step-title">Step 7</h4> Transfer the hot Brussels sprouts to a serving dish and immediately drizzle with the balsamic glaze. The heat from the sprouts will help the glaze adhere and penetrate slightly. Sprinkle with Parmesan cheese if using – the residual heat will slightly melt the cheese. </li> <li class="MethodStepper"> <h4 class="step-title">Step 8</h4> Garnish with fresh thyme leaves for a bright, herbaceous note and serve immediately while the sprouts are still crispy. These are best enjoyed fresh from the air fryer, as they can soften if left to sit too long. </li> </ol>

Chef’s Notes

A few helpful details for making this recipe.

Why do my Brussels sprouts get soggy instead of crispy in the air fryer?

Soggy sprouts typically result from overcrowding the air fryer basket, which creates steam rather than dry heat. Work in batches, arrange them cut-side down in a single layer, and ensure they're thoroughly dried after washing. Preheating your air fryer is also crucial for immediate caramelisation.

Can I make balsamic Brussels sprouts in a conventional oven instead?

Absolutely! Roast halved sprouts at 200°C for 20-25 minutes on a baking sheet, tossing halfway through. They'll take longer than in an air fryer but will still caramelise beautifully. Drizzle with balsamic glaze after roasting for that same sweet-tangy finish.

What's the best way to prep Brussels sprouts to ensure maximum crispiness?

For ultimate crispiness, trim the stem ends, remove any damaged outer leaves, and cut sprouts in half lengthwise. Pat them completely dry before adding oil (moisture creates steam). The cut surface creates more area for caramelisation, and smaller sprouts tend to crisp better than larger ones.
