I’ve always loved Brussels sprouts, but I’ll admit, roasting them until crispy perfection in the air fryer has completely changed my perspective. Their natural sweetness comes alive with just a hint of char, and the texture is perfectly crunchy on the outside while tender inside. Pairing them with a vibrant preserved lemon-Caesar dressing brings a bright, zesty punch that elevates this humble vegetable to a centerpiece-worthy dish.
Cooking this recipe has become my little weekend ritual. The air fryer makes it effortless to get that golden, crispy finish without standing over a hot oven, and the preserved lemon in the dressing adds a flavor depth I never knew Brussels sprouts could handle. It’s bold, tangy, and savory all at once, making this dish not just a side but a conversation starter at the table.
What You Need To Make This Recipe
Brussels Sprouts: These tiny green powerhouses are full of flavor and nutrition. When trimmed and halved, they crisp up beautifully in the air fryer, offering a satisfying bite that balances perfectly with the tangy dressing.
Olive Oil: A high-quality olive oil helps the Brussels sprouts caramelize in the air fryer. It adds richness without overpowering their natural flavor and ensures the outside crisps nicely.
Salt and Black Pepper: These simple seasonings are essential to bring out the natural sweetness of the sprouts. Season generously to enhance every bite and create a perfectly balanced flavor profile.
Preserved Lemon: Preserved lemon adds a unique citrusy tang with a subtle depth of saltiness. It brightens the creamy Caesar dressing and complements the roasted sprouts beautifully.
Parmesan Cheese: Freshly grated Parmesan adds savory richness and a nutty flavor that makes the dressing indulgent without feeling heavy.
Garlic: Minced garlic adds a fragrant, aromatic quality to the dressing, giving it a classic Caesar kick with a little extra depth.
Anchovy Paste (optional): Anchovy paste provides that traditional umami punch for the Caesar dressing. It’s optional, but even a small amount makes a big difference in flavor.
Greek Yogurt or Mayonnaise: These creamy bases help emulsify the dressing, balancing the tangy lemon and savory Parmesan for a luscious coating on the sprouts.
Dijon Mustard: A touch of Dijon adds subtle heat and complexity to the dressing, helping it cling to each crispy sprout perfectly.

How to Make Air-Fried Brussels Sprouts with Preserved Lemon-Caesar Dressing
Prepare the Brussels Sprouts
Rinse the Brussels sprouts thoroughly, trim off the ends, and cut them in half. Pat them dry to ensure they crisp up nicely in the air fryer.
Season the Sprouts
Place the halved sprouts in a bowl, drizzle with olive oil, and season with salt and black pepper. Toss them well so every piece is lightly coated.
Air-Fry the Sprouts
Preheat the air fryer to 375°F (190°C). Place the Brussels sprouts in a single layer and cook for 15–18 minutes, shaking halfway through, until golden and crispy.
Make the Dressing
In a small bowl, combine preserved lemon, Parmesan cheese, minced garlic, anchovy paste (if using), Greek yogurt or mayonnaise, and Dijon mustard. Mix until smooth and creamy.
Toss and Serve
Once the sprouts are done, transfer them to a large bowl. Drizzle the preserved lemon-Caesar dressing over the sprouts and toss to coat evenly. Serve immediately while crispy and warm.
Tips for Making this Recipe
- Don’t overcrowd the air fryer basket; this ensures the Brussels sprouts get crispy.
- Patting the sprouts dry is key—any excess moisture will steam them instead of roasting.
- Adjust the amount of preserved lemon to taste; a little goes a long way.
- If you prefer extra crunch, sprinkle a bit of panko over the sprouts before air-frying.
- Anchovy paste is optional but highly recommended for a classic Caesar depth.
- Serve immediately after tossing with the dressing to maintain crispiness.
FAQs
Can I make this recipe without an air fryer?
Yes! You can roast the Brussels sprouts in the oven at 400°F (200°C) for 20–25 minutes, flipping halfway through.
Can I use fresh lemon instead of preserved lemon?
Fresh lemon juice works, but preserved lemon adds a unique, salty-citrus depth that’s hard to replicate.
Is this recipe vegan-friendly?
To make it vegan, substitute Parmesan with nutritional yeast and use a vegan mayo or yogurt.
Can I prepare the dressing in advance?
Yes, the dressing can be made up to 2 days in advance and stored in the fridge.
How do I store leftovers?
Store leftover sprouts and dressing separately in airtight containers in the fridge for up to 2 days. Reheat the sprouts in the air fryer to bring back some crispiness.
