Estimated. Worked out from the ingredients using the UK food composition tables, so treat it as a guide rather than a measurement. A typical recipe lands within about a quarter of the true figure. Makes about 4.
Ingredients
- 500g Brussels sprouts, halved
- 2 tablespoons olive oil
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 cup grated Parmesan cheese
- 1 tablespoon balsamic vinegar
Cooking Steps
Preheat the air fryer to 200°C (400°F).
In a large bowl, toss the halved Brussels sprouts with olive oil, garlic powder, salt, and black pepper until evenly coated.
Sprinkle the grated Parmesan cheese over the Brussels sprouts and toss again to combine.
Place the Brussels sprouts into the air fryer basket in a single layer. Cook for 10 minutes, shaking the basket halfway through for even crisping.
After 10 minutes, check for desired crispiness. If needed, cook for an additional 2-3 minutes.
Drizzle with balsamic vinegar before serving for added flavor.
Optional Enhancements
- 1. Use nutritional yeast instead of Parmesan for a dairy-free option.
- 2. Replace balsamic vinegar with lemon juice for a brighter flavor.
- 3. Add a pinch of red pepper flakes for a spicy kick.
Plant & Growing Tips
Brussels Sprouts
- Brussels sprouts are a cool-season crop; plant in late summer for an autumn/winter harvest in regions with mild winters.
- They require firm, rich soil and full sun, along with consistent moisture throughout their growing period.
- Space plants 18-24 inches apart to allow for good air circulation and stalk development.
Natural Pest Control
- Use row covers to protect young Brussels sprouts plants from cabbage white butterflies, which lay eggs that hatch into destructive cabbage worms.
- Monitor for aphids and spray affected areas with a strong jet of water or an insecticidal soap solution.
Harvest
Brussels Sprouts
- Harvest sprouts from the bottom of the stalk upwards when they are firm, tight, and about 1-2 inches in diameter, twisting them off cleanly.
Storing & Freezing
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the air fryer at 160°C (320°F) for 5 minutes to retain crispiness.
