Sweet Potato Chips

Ingredients

• 680 g (1½ pounds)sweet potatoes
• 80 ml (⅓ cup)olive oil
• to tastekosher salt

Instructions

1. 1

   Slice the potatoes

   Heat the oven to 150°C (300°F). Line several baking sheets with parchment paper. Use a mandolin on its thinnest setting to slice the sweet potatoes into paper-thin rounds; a knife works too, but takes longer.

2. 2

   Coat and arrange

   Put all the rounds in a large bowl and gently toss them with the olive oil until coated. Arrange them in a single layer on the prepared baking sheets.

3. 3

   Bake until crisp

   Sprinkle the rounds lightly with kosher salt. Bake for 20–25 minutes, until crisp and golden around the edges. Leave them on the baking sheets to cool for 5 minutes, then transfer to a bowl or a storage bag. If any have soft centres, return them to the oven for about 5 minutes.

What are sweet potato chips?

Sweet potato chips are thin slices cooked until crisp, here in an American-style baked snack or side-dish version. The method relies on very thin cuts and a single layer rather than deep-frying.

Baking makes this a straightforward choice for serving alongside burgers and sandwiches. The three ingredients keep the flavour simple, letting the sweet potato's natural sweetness come through.

Nutrition and macros by portion

The nutrition label shows one serving as written: 152 calories, 1g protein, 17g carbs, 9g fat.

The sweet potatoes provide most of the carbohydrate, while olive oil contributes most of the fat. The recipe contains little protein, so serve a portion with a protein-rich main such as a bean patty or another suitable filling to make a more balanced plate.

Why slice them thinly?

Thin slices: Cut the rounds as evenly and thinly as you can so they have a chance to crisp in the stated baking time. A mandolin makes this quicker; take care when using it.

Coating and arranging

Olive oil: Toss gently so the slices are coated without breaking them. The recipe uses enough oil to coat the whole batch.

Single layer: Spread the rounds across several baking sheets without overlapping. Crowded slices are less likely to crisp evenly.

Look for crisp edges

Doneness: Bake for 20–25 minutes, watching for crispness and golden edges. The slices may not all finish at exactly the same time if their thickness varies.

Soft centres: Let the chips cool on the baking sheets for 5 minutes, then check them. Return any with soft centres to the oven for about 5 minutes, as directed.

When to serve them

As a side: Serve the chips with burgers or sandwiches, or offer them as a snack. Their lightly salted, sweet flavour works well with a simple main.

Salt and seasoning

Kosher salt: Sprinkle lightly before baking and adjust the amount to taste. A modest first sprinkle lets the sweet potato remain the main flavour.

Recipe notes & tips

• Use a mandolin on its thinnest setting for paper-thin rounds.
• Line several baking sheets before you start slicing.
• Toss the slices gently so they stay intact.
• Keep the rounds in a single layer on the baking sheets.
• Cool the chips on the sheets for 5 minutes before moving them.
• Return any chips with soft centres to the oven for about 5 minutes.

Variations

• Adjust the salt: Sprinkle on a little more or less to suit your taste.
• Change the cut: Use a sharp knife if you do not have a mandolin, slicing as thinly as possible.
• Serve as a side: Pair the chips with burgers or sandwiches.
• Bake in batches: Use multiple baking sheets to keep the slices in a single layer.

Common mistakes to avoid

• Slices too thick: Cut them paper-thin so they have a better chance of crisping in the stated time.
• Uneven slices: Aim for consistent thickness so the rounds bake more evenly.
• Overlapping rounds: Arrange them in a single layer across several sheets.
• Too much handling: Toss gently to coat without breaking the slices.
• Soft centres: Return the affected chips to the oven for about 5 minutes.

How to store

Once cool, store the chips in a bowl or plastic bag. They are best enjoyed while crisp; if they soften, return them to the oven for about 5 minutes and check for crispness.
