How to Prepare Jamie Oliver Swede and Parsnip Mash – Simple Steps

Step 1: Prepare the Vegetables

Peel the swede and parsnips and cut them into evenly sized chunks. Keeping the pieces similar in size helps them cook at the same rate.

Step 2: Boil Until Tender

Place the vegetables in a large pan of salted water. Bring to a boil, then simmer for 20–25 minutes until completely soft and easily pierced with a knife.

Step 3: Drain and Steam Dry

Drain the vegetables well and return them to the hot pan for 1–2 minutes. This allows excess moisture to evaporate, giving a richer mash.

Step 4: Mash Until Smooth

Add the butter and mash thoroughly using a potato masher or hand blender. Work until the texture is smooth and creamy.

Step 5: Adjust Creaminess and Seasoning

Stir in milk or cream a little at a time until the mash reaches your preferred consistency. Season with salt, pepper, and nutmeg or herbs if using.

Step 6: Serve Warm

Serve immediately while hot, or cover and keep warm until ready to bring to the table.
