🧊 When Should You Blanch Brussels Sprouts?

Blanching is recommended when you want to:

• Freeze Brussels sprouts
• Prepare them in advance for roasting or frying
• Reduce bitterness
• Preserve bright green colour and firm texture

Blanching is especially useful during harvest season or bulk cooking.

🥬 Step-by-Step: How to Blanch Brussels Sprouts

1️⃣ Prepare the Brussels Sprouts

• Remove loose or damaged outer leaves
• Trim the stem ends slightly
• Wash thoroughly under cold running water
• Leave small sprouts whole; cut large ones in half

Keeping sizes similar ensures even blanching.

2️⃣ Bring Water to a Rolling Boil

• Fill a large saucepan with water
• Bring to a rolling boil
• Add a pinch of salt (optional, helps colour and flavour)

3️⃣ Blanch the Brussels Sprouts

Carefully add the sprouts to boiling water.

Blanching times:

• Small sprouts: 3 minutes
• Medium sprouts: 4 minutes
• Large or halved sprouts: 5 minutes

They should be tender-crisp, not fully cooked.

4️⃣ Cool Immediately

• Transfer sprouts straight into ice-cold water
• Leave for the same time as blanching
• Drain thoroughly

This stops cooking instantly and locks in colour.

5️⃣ Dry and Use or Store

• Pat sprouts dry with a clean tea towel or kitchen paper
• Use immediately or prepare for freezing

❄️ How to Freeze Blanched Brussels Sprouts

1. Spread cooled sprouts in a single layer on a tray
2. Freeze for 1–2 hours until firm
3. Transfer to labelled freezer bags or airtight containers

Storage life:
