Why Choose the Air Fryer for Brussels Sprouts?

Using an air fryer to cook vegetables like Brussels sprouts offers several advantages:

1. Even Crispiness Without Deep Frying

The rapid hot air circulation in an air fryer mimics the results of deep frying, yielding crispy exteriors with tender interiors—without the need for copious amounts of oil.

2. Quick Cook Time

Brussels sprouts typically take 30–40 minutes in the oven. In an air fryer, they’re ready in 15 to 20 minutes.

3. Enhanced Flavor Retention

The air fryer intensifies the natural nutty flavor of Brussels sprouts, which pairs beautifully with garlic and parmesan.

4. Healthier Option

By using minimal oil, this recipe reduces overall fat content while keeping the dish flavorful and filling.

Ingredients You’ll Need

For about 4 servings:

  • 500g (1 lb) fresh Brussels sprouts, trimmed and halved

  • 3 tablespoons olive oil

  • 4 garlic cloves, minced (or 1½ teaspoons garlic powder if preferred)

  • ½ teaspoon salt, or to taste

  • ½ teaspoon freshly ground black pepper

  • ⅓ cup grated parmesan cheese (plus extra for garnish)

  • Optional: pinch of chili flakes or smoked paprika for extra depth

Equipment

  • Air fryer (any model with a basket or tray-style works)

  • Mixing bowl

  • Chef’s knife

  • Cutting board

  • Measuring spoons and cups

  • Tongs or spatula for flipping

Step-by-Step Recipe: Garlic Parmesan Roasted Brussels Sprouts in the Air Fryer

Step 1: Prep the Brussels Sprouts

Start by washing the Brussels sprouts thoroughly. Remove any discolored or tough outer leaves. Cut off the tough stem ends and then slice each sprout in half, lengthwise.

If your sprouts are particularly large, you can quarter them for more even cooking. If they are small, you might leave them whole.

Step 2: Season and Toss

In a large mixing bowl, combine:

  • 3 tablespoons of olive oil

  • Minced garlic (or garlic powder)

  • Salt and pepper

Toss the halved sprouts in this mixture until they are evenly coated. Make sure the garlic is distributed throughout, but not clumping.

Step 3: Add the Parmesan

Add in the grated parmesan cheese and mix again. The cheese will adhere slightly to the oiled surface of the Brussels sprouts and crisp up nicely during cooking.

Step 4: Preheat the Air Fryer

Set your air fryer to 190°C (375°F) and let it preheat for about 3 minutes. This helps start the crisping process immediately.

Step 5: Cook in Batches (if necessary)

Place the Brussels sprouts in a single layer in the air fryer basket or tray. Overcrowding will result in uneven cooking, so cook in batches if needed.

Air fry at 190°C (375°F) for 15–18 minutes, shaking or flipping the sprouts halfway through cooking to ensure even browning.

Cooking time can vary based on your air fryer model and the size of your sprouts.

Step 6: Check for Doneness

The Brussels sprouts should be:

  • Golden brown and crisp on the outside

  • Tender on the inside

  • Garlic slightly toasted but not burnt

  • Cheese melted and slightly crunchy in spots

If not yet crispy, add another 2–3 minutes.

Step 7: Garnish and Serve

Remove from the air fryer and let cool for a minute. Garnish with extra grated parmesan and an optional dash of chili flakes or lemon zest for brightness.

Serve immediately for the best texture and flavor.

Pro Tips for Perfect Garlic Parmesan Brussels Sprouts

1. Dry the Sprouts Thoroughly

Any residual water can cause steaming instead of crisping. Use a clean kitchen towel or paper towel to pat them dry after washing.

2. Don’t Overdo the Oil

Too much oil can lead to soggy sprouts. Three tablespoons is just enough to coat and crisp.

3. Use Fresh Garlic with Caution

Fresh minced garlic can burn if it’s sitting directly on the surface for too long. You can stir it in halfway through cooking or opt for garlic powder to avoid bitterness.

4. Try Panko for Extra Crunch

Mix in 1–2 tablespoons of panko breadcrumbs with the cheese for an extra crispy coating.

5. Watch the Cooking Time Closely

Once they start browning, Brussels sprouts can go from perfect to overcooked in under a minute. Monitor closely during the last 3–5 minutes.

Variations to Try

1. Balsamic Glaze Finish

Drizzle a little balsamic reduction over the sprouts before serving for a sweet-tangy contrast.

2. Cheesy Upgrade

Swap parmesan for pecorino romano, gruyère, or even cheddar for a different flavor profile.

3. Bacon & Brussels

Toss in chopped pre-cooked bacon pieces after cooking for a smoky crunch.

4. Asian-Inspired

Use sesame oil instead of olive oil, and sprinkle with toasted sesame seeds and a dash of soy sauce.

5. Lemon Garlic Herb

Add lemon zest and chopped parsley right after air frying for a fresher finish.

What to Serve With Garlic Parmesan Brussels Sprouts

These roasted sprouts are incredibly versatile. Pair them with:

  • Grilled meats (chicken, steak, or lamb)

  • Air fryer salmon or cod

  • Roasted potatoes or sweet potato mash

  • Grain bowls with quinoa or farro

  • Vegetarian pasta dishes

  • Holiday meals (Thanksgiving, Christmas)

They also make a stellar snack on their own—especially when served with a creamy dipping sauce like garlic aioli, ranch, or even spicy sriracha mayo.

Storage and Reheating

Storage:

  • Let the Brussels sprouts cool to room temperature before storing.

  • Keep in an airtight container in the fridge for up to 3 days.

Reheating:

  • Air fryer: Reheat at 180°C (350°F) for 3–5 minutes to restore crispiness.

  • Oven: Bake at 180°C (350°F) for 8–10 minutes.

  • Microwave: Not recommended as it will make them soggy.

Nutritional Benefits

Brussels sprouts are a nutritional powerhouse, rich in:

  • Vitamin K (supports bone health)

  • Vitamin C (boosts immunity)

  • Fiber (aids digestion)

  • Antioxidants (help reduce inflammation)

Pairing them with garlic and olive oil adds heart-healthy fats and anti-inflammatory compounds. The parmesan cheese brings in a dose of calcium and protein.

It’s a guilt-free dish that tastes indulgent but supports your health goals—especially if you’re on a low-carb, keto, or Mediterranean diet.
