Variations

• Spicy version: Add a pinch of red pepper flakes to the Brussels sprouts or a dash of hot sauce to the aioli.
• Cheesy finish: Sprinkle freshly grated Parmesan over the sprouts during the last 5 minutes of roasting.
• Citrus twist: Add orange or lime zest to the aioli for a refreshing variation.
• Vegan option: Use a plant-based mayonnaise to make the aioli dairy-free and vegan.
• Smoky flavor: Use smoked paprika in place of or alongside garlic powder for a deeper flavor profile.

storage/reheating

Store any leftover Brussels sprouts in an airtight container in the refrigerator for up to 3 days. Reheat in a 400°F (200°C) oven for 8–10 minutes to restore crispness. Avoid microwaving as it can make the sprouts soggy. Garlic aioli should be stored separately in a sealed container in the refrigerator and used within 3–4 days.

FAQs

Why are my Brussels sprouts not crispy?

Ensure the sprouts are dry before roasting and spread them in a single layer, cut-side down, without overcrowding the pan.

Can I make the garlic aioli ahead of time?

Yes, it can be prepared up to 3 days in advance and stored in the refrigerator in an airtight container.

What can I use instead of mayonnaise in the aioli?

You can use Greek yogurt or a vegan mayo alternative, though the texture and taste will differ slightly.

Are frozen Brussels sprouts suitable for this recipe?

Fresh Brussels sprouts are preferred for optimal texture, but thawed and well-dried frozen sprouts can be used in a pinch.

Can I add other vegetables?

Yes, this method works well with cauliflower, carrots, or broccoli—just adjust roasting times as needed.

Is garlic powder necessary?

It enhances flavor, but you can use fresh minced garlic tossed with the sprouts if preferred.

What’s the best oil for roasting?

Olive oil adds flavor, but any neutral oil with a high smoke point, such as avocado or canola oil, also works well.

Can I air-fry the Brussels sprouts?

Yes, cook them at 375°F (190°C) for 12–15 minutes in an air fryer, shaking halfway through for even crisping.

What should I serve with these Brussels sprouts?

They pair well with grilled meats, roasted chicken, or can be served as a standalone appetizer with the aioli.

How do I make the aioli more flavorful?

Add a touch of smoked paprika, chopped herbs, or a splash of vinegar to enhance the complexity of the dip.
