Why Choose This Recipe?

Air fryer Brussels sprouts are low-carb and nutrient-dense. They’re rich in fiber, vitamins C and K, and antioxidants.

Why This Recipe Works

The air fryer’s hot air circulation crisps the sprouts’ outer leaves. A small amount of oil enhances flavor and promotes browning.

High heat locks in nutrients and creates a crunchy texture. Balanced seasoning, like garlic and parmesan, boosts taste without overpowering.

The recipe’s simplicity ensures success for all skill levels. It aligns with low-carb and gluten-free diets while delivering bold flavors.

How to Make Air Fryer Brussels Sprouts

1. Prepare the Brussels sprouts. Rinse them under cold water. Trim the woody ends. Cut each sprout in half lengthwise. Remove any yellowed outer leaves.
2. Season the sprouts. Place halved sprouts in a mixing bowl. Add olive oil, garlic powder, sea salt, and black pepper. Toss to coat evenly.
3. Preheat the air fryer. Set it to 400°F (200°C). Let it heat for 3 minutes.
4. Arrange the sprouts. Place sprouts in the air fryer basket in a single layer. Avoid overcrowding for even cooking.
5. Cook the sprouts. Air fry for 12-15 minutes. Shake the basket halfway through to ensure even crisping.
6. Check for doneness. Sprouts should be golden brown and crispy on the edges. If not, cook for an additional 2-3 minutes.
7. Add optional toppings. Sprinkle parmesan cheese or drizzle balsamic vinegar over the sprouts. Toss lightly.
8. Serve immediately. Transfer to a plate. Garnish with red pepper flakes, bacon, or herbs if desired.

Total Time: 20-25 minutes (10 minutes prep, 12-15 minutes cooking)

Tips for Success

• Ensure even sizing: Cut sprouts uniformly for consistent cooking.
• Don’t skip the shake: Shaking the basket halfway prevents burning and promotes even crisping.
• Use parchment paper: Line the basket for easier cleanup, but ensure air can circulate.
• Make ahead: Trim and halve sprouts up to a day in advance. Store in an airtight container in the fridge.
• Freeze for later: Flash-freeze cooked sprouts on a tray, then transfer to a freezer bag. Reheat in the air fryer at 375°F for 5-7 minutes.
• Avoid over-oiling: Too much oil makes sprouts soggy. Stick to 2 tablespoons for 1 pound.

Customizing the Recipe

Add variety with different flavors. Try smoked paprika for a smoky kick. Sprinkle nutritional yeast for a cheesy, vegan twist.

For spice, use cayenne pepper or hot sauce. Fresh herbs like rosemary or thyme add earthy notes.

Experiment with citrus zest for brightness. Swap olive oil for truffle oil for a gourmet touch.

Mix in roasted garlic for deeper flavor. Tailor the dish to your taste or dietary needs.

Common Mistakes to Avoid

• Overcrowding the basket: Too many sprouts steam instead of crisp. Cook in batches if needed.
• Skipping the preheat: A cold air fryer leads to uneven cooking. Always preheat to 400°F.
• Using wet sprouts: Damp sprouts won’t crisp. Pat them dry after rinsing.
• Over-seasoning: Too much salt or spice overwhelms the natural flavor. Start with small amounts.
• Ignoring size differences: Unevenly cut sprouts cook at different rates. Aim for uniform halves.

Storage and Reheating

Store leftovers in an airtight container in the fridge for up to 4 days. For longer storage, freeze cooked sprouts in a freezer-safe bag for up to 3 months.

To reheat, place in the air fryer at 375°F for 5-7 minutes. This restores crispiness. Avoid microwaving, as it makes sprouts soggy. Ensure sprouts are fully cooled before storing to prevent condensation.

Pairing Suggestions

Serve with grilled chicken or salmon for a keto-friendly meal. Pair with a creamy cauliflower mash for a low-carb side.

A crisp white wine like Sauvignon Blanc complements the nutty flavors. For dessert, try a keto chocolate mousse.

Avoid carb-heavy sides like potatoes to maintain dietary alignment. A light cucumber salad adds refreshing contrast.

Frequently Asked Questions

Can I use frozen Brussels sprouts?

Frozen sprouts work but may be less crispy. Thaw and pat dry before cooking. Increase cooking time by 2-3 minutes.

What if I don’t have an air fryer?

Roast in an oven at 425°F for 20-25 minutes on a baking sheet. Flip halfway for even browning.

Are these Brussels sprouts keto-friendly?

Yes, they’re low in net carbs (6g per cup). Avoid high-carb toppings like sugary glazes.

Can I make this vegan?

Skip parmesan or use nutritional yeast. Ensure bacon or other toppings are plant-based.

How do I prevent bitter sprouts?

Choose smaller, fresh sprouts. They’re sweeter. Don’t overcook, as this intensifies bitterness.

Can I double the recipe?

Yes, but cook in batches. Overcrowding reduces crispiness. Keep the basket in a single layer.

How do I know when the sprouts are done?

Look for golden-brown, crispy edges. The interior should be tender but not mushy.
