Whether you’re seeking a vibrant side, a meatless main, or a bold appetizer, this dish brings restaurant-level taste to home kitchens, all in under 30 minutes.
Why Air Fry Brussels Sprouts?
Air fryers have revolutionized home cooking, especially for vegetables prone to mushy textures when roasted or steamed. The rapid, circulating heat of an air fryer delivers unbeatable crispiness, amplifies caramelized edges, and preserves the sprouts’ nutty sweetness. Compared to oven roasting, air frying:
- Speeds up cooking—typically 10-15 minutes, versus 20-25 for oven methods.
- Enhances crispness and browning thanks to even, direct heat.
- Requires less oil, making for a lighter finished dish.
- Creates consistently tender interiors and crunchy exteriors.
Start with fresh, similarly sized Brussels sprouts for the most even results. If using frozen, allow a few extra minutes and higher temperature to drive off moisture and crisp effectively.
Preserved Lemon Caesar Dressing: A Modern Twist
Classic Caesar dressing is luscious and savory, built on egg yolks, anchovies, garlic, Dijon, and hard cheese. This recipe reinvents Caesar with the sharp, punchy fruitiness of preserved lemon—a Moroccan pantry staple made by salting and fermenting whole lemons. Preserved lemon brings a bold, saline brightness not found in fresh lemon juice, elevating the dressing while harmonizing beautifully with the earthy sprouts.
- Preserved lemon peel replaces much of the traditional lemon flavor, lending complexity and zip.
- Anchovies, garlic, and Parmesan ground the dressing in umami.
- Mayonnaise simplifies preparation—no need for raw eggs or slow emulsion.
- Dijon and olive oil smooth and enrich flavor.
The result is a creamy, intensely flavored Caesar that coats the sprouts and stays lush, not heavy.

Step-by-Step: Making Air Fryer Brussels Sprouts
1. Prep the Brussels Sprouts
- Remove sprouts from the stalk if needed.
- Rinse and thoroughly dry—moist sprouts won’t crisp.
- Trim stem ends and halve each sprout lengthwise.
- Toss with olive oil, salt, pepper, and chili flakes if desired. Coat well to promote browning.
2. Air Fry to Perfection
- Preheat air fryer to 360°F (or as directed by manufacturer).
- Arrange sprouts in a single layer for air circulation—larger batches may require cooking in rounds.
- Cook for 10-12 minutes, shaking or flipping halfway, until deeply browned and crispy at the edges.
Note: For frozen sprouts, use petite varieties and increase cook time to 14-16 minutes at 380°F. Do not halve frozen sprouts, as texture may suffer.

3. Prepare the Preserved Lemon Caesar Dressing
- Finely dice or mash the preserved lemon peel, anchovies, and garlic into a rough paste.
- Combine paste with mayonnaise, Dijon, Parmesan, olive oil, and lemon juice (if using) in a bowl.
- Whisk until smooth and creamy. Season with salt and pepper.
4. Dress and Finish
- Transfer hot sprouts to a large bowl.
- Toss with desired amount of preserved lemon Caesar dressing (or serve dressing on the side for dipping/drizzling).
- Optional: Finish with a shower of freshly grated Parmesan, extra preserved lemon zest, or fresh herbs.
Tips for Ultimate Crispiness
- Uniform size: Choose sprouts of similar size or halve the largest ones so all pieces cook evenly.
- Dry thoroughly: Residual moisture impedes browning—after rinsing, dry with towels before oiling.
- Single layer: Do not overcrowd the air fryer basket; cook in batches if needed.
- Shake or toss: Move sprouts halfway through to ensure every bit gets crispy.
- Serve immediately: Air-fried vegetables lose crispness as they cool, so toss and serve right away.
Flavor Variations and Substitutions
- Add cheese: Toss hot sprouts with a handful of grated Parmesan or Pecorino.
- Breadcrumb crunch: Sprinkle with crisp panko, toasted in olive oil, for extra texture.
- Buffalo flair: Toss air-fried sprouts in buffalo sauce, then dip in blue cheese.
- Vegan option: Swap anchovies and Parmesan for capers and nutritional yeast in the dressing.
- Lemon alternatives: Use regular lemon zest and juice if preserved lemons are unavailable. Adjust salt to taste.
Serving Suggestions
- As a side dish: Pair with grilled steak, roasted chicken, or broiled fish.
- In salads: Layer atop mixed greens with shaved Parmesan and toasted nuts.
- Vegetarian main: Serve over grain bowls with quinoa and chickpeas.
- Bold appetizer: Make mini skewers for cocktail parties, dipping each in Caesar dressing.
Frequently Asked Questions (FAQs)
Can I use frozen Brussels sprouts in this recipe?
Yes. Use petite, whole frozen sprouts, increase the air fryer temperature to 380°F, and add 2-4 extra minutes to cook time. Do not halve frozen sprouts; they may become mushy. Fresh results offer superior texture and flavor.
What is preserved lemon, and where can I find it?
Preserved lemon is a lemon cured in salt (sometimes also lemon juice) for several weeks until the peel becomes soft and intensely flavorful. It is common in North African and Mediterranean cuisine and available at Middle Eastern markets, some grocery stores, or online.
Can I roast these Brussels sprouts in the oven?
Absolutely. Toss sprouts as directed, spread on a baking sheet, and roast at 400°F for 20-25 minutes, flipping halfway. Oven-roasted sprouts are delicious but may lack the air fryer’s extra crisp.
Is the Caesar dressing safe for vegetarians?
This classic Caesar contains anchovies and Parmesan (the latter not always vegetarian due to rennet). For a vegetarian version, omit anchovies and use a vegetarian-friendly hard cheese.
Can I make the dressing ahead?
Yes. The preserved lemon Caesar dressing keeps well, refrigerated in a sealed jar, for up to 1 week. Stir or shake before using.
How do I avoid soggy sprouts?
Use fresh, dry sprouts, toss evenly with oil, avoid overcrowding, and serve promptly. A single layer ensures maximum crispness.
Storing and Reheating
- Storage: Air-fried sprouts are best enjoyed fresh. For leftovers, refrigerate in an airtight container for up to 2 days.
- Reheat: For the best texture, reheat in the air fryer at 350°F for 3-5 minutes until crisped, or in a hot oven.
- Do not microwave: Microwaving will soften and steam the sprouts, losing their crunchy edge.
Nutritional Benefits
- Brussels sprouts are rich in fiber, vitamin C, and antioxidants.
- Olive oil provides heart-healthy fats.
- Preserved lemon is low-calorie but naturally high in flavor, cutting the need for excess salt.
- Caesar dressing offers protein and calcium, especially if using Parmesan; substitute with nutritional yeast for dairy-free options.
Advanced Prep and Meal Planning
- Preserved lemon Caesar dressing can be made several days ahead and refrigerated.
- Halved, oiled sprouts may be prepped several hours before cooking and chilled; bring to room temperature before frying.
- The recipe easily doubles; cook sprouts in batches for crowds.
Troubleshooting & Chef Secrets
- Uneven browning? Toss or shake the basket more often; avoid stacking sprouts.
- Dense or tough sprouts? Try smaller, younger sprouts; older ones can be woody. Parboil for 3 minutes before air frying if large or dense.
- Missing preserved lemons? Make a quick substitute: zest a fresh lemon, toss with salt, and let sit for 30 minutes before using.
