Jamie Oliver Mustard Potato Mash Ingredients List
Serves 4

- 50 g butter
- 80–100 ml warm milk

How to Prepare Jamie Oliver Mustard Potato Mash – Simple Steps
Step 1: Prepare the Potatoes Properly
Peel potatoes and cut into even chunks.
Place in a saucepan with cold salted water.
Starting with cold water ensures even cooking from the inside out.
Bring to a gentle boil and cook for 15–20 minutes until fork-tender.
Step 2: Drain and Steam-Dry
Drain potatoes thoroughly.
Return them to the warm pan and allow them to steam-dry for 1–2 minutes.
This removes excess moisture and prevents watery mash.
Step 3: Mash While Hot
Mash potatoes while still hot using a potato masher or ricer.
Avoid overworking, as too much mixing releases starch and creates a gluey texture.
Step 4: Add Butter and Milk
Stir in butter first so it melts evenly.
Gradually add warm milk while mixing gently.
Warm milk blends smoothly and maintains temperature.
Step 5: Incorporate Mustard Carefully
Add Dijon mustard gradually, tasting as you go.
Mustard should enhance the mash, not dominate it.
Season with salt and black pepper.
Step 6: Adjust Texture and Serve
If the mash feels too thick, add a small splash of milk.
Serve immediately while warm and creamy.

FAQs
What type of mustard works best in mustard potato mash?
Dijon mustard works best because it adds smooth, balanced sharpness without overpowering the potatoes. Wholegrain mustard can also be added for texture, but strong English mustard should be used sparingly.
Why is my mashed potato gluey and sticky?
Gluey mash usually happens when potatoes are overmixed or blended too much. Overworking releases excess starch, so mash gently and stop as soon as the texture becomes smooth.
Can I make mustard potato mash ahead of time?
Yes, you can prepare it up to a day in advance. Store it in the refrigerator and reheat gently with a splash of warm milk to restore its creamy texture.
How do I balance the mustard flavour if it’s too strong?
If the mustard tastes overpowering, add a little extra butter or warm milk to soften the sharpness. Taste gradually rather than adding mustard all at once.
