Free Recipe for Thermomix · Sides
These crispy sliced roasted potatoes are everything you want in a potato side: shatteringly crisp edges, soft fluffy centres, and endless surface area for the oil and salt to cling to. The secret is slicing the potatoes thin and even, and your Thermomix does exactly that with the Wunderslicer Thermo Cutter & Slicer attachment.
These crispy sliced roasted potatoes are sliced in the Thermomix and roasted in the oven in about 1 hour and 15 minutes, using just five ingredients.
If you have ever wrestled a mandoline or spent ten minutes hand-slicing potatoes into even coins, this recipe is going to change your roast potato game. Sliced thin and roasted upright (or spread flat), the potatoes turn golden and crisp all over instead of just on the flat side. It is a simple technique with a genuinely impressive result.
The slicing is where the Thermomix earns its keep. Fit the Wunderslicer attachment, drop your potatoes down the chute, and you have a pile of perfectly even slices in seconds. Even, thin slices mean even cooking and maximum crispness, without the fiddle and without the risk to your fingertips.
