🧊 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
- Spread cooled sprouts in a single layer on a tray
- Freeze for 1–2 hours until firm
