🧊 When Should You Blanch Sprouts?
Blanch sprouts when you want to:
- Freeze them for long-term storage
- Reduce bitterness before roasting or frying
- Prepare sprouts in advance for meals
- Preserve colour and firmness
Blanching is especially useful during harvest season or festive meal prep.
🥬 Step-by-Step: How to Blanch Sprouts
1️⃣ Prepare the Sprouts
- Trim the dry stem ends
- Remove any loose or yellow outer leaves
- Wash thoroughly
- Leave small sprouts whole; halve large ones
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, improves flavour and colour)
3️⃣ Blanch the Sprouts
Carefully add sprouts to the boiling water.
Blanching times:
- Small sprouts (whole): 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 step stops cooking and locks in colour.
5️⃣ Dry and Use or Store
- Pat dry with kitchen paper or a clean tea towel
- Use immediately or prepare for freezing
❄️ How to Freeze Blanched Sprouts

- Freeze for 1–2 hours until firm

🍽️ How to Use Blanched Sprouts
