💧 Boiling

Best for: Mashing, purées, or simple sides

• Small sprouts: 6–8 minutes

They should be just tender when pierced with a knife.

Steaming helps prevent waterlogging and bitterness.

Turn halfway through for even browning.

Best for: Quick, flavour-packed sides

• Halved sprouts: 10–12 minutes

Start cut-side down for maximum caramelisation.

🥘 Microwave

Best for: Speed and convenience

• Whole sprouts: 5–7 minutes
• Add a small amount of water and cover

Stir halfway through cooking.

❄️ Cooking Frozen Brussels Sprouts

• Boiling: 8–10 minutes
• Steaming: 10–12 minutes
• Roasting: 30–40 minutes (from frozen)

Do not thaw before cooking for best texture.

🧂 How to Tell When Brussels Sprouts Are Done

Perfectly cooked Brussels sprouts should be:

• Not falling apart
• Slightly firm in the centre

If they smell strongly sulphurous, they’re likely overcooked.
