Ingredients
- 2 medium sweet potatoes (about 1 pound or 450 g)
- 2 tablespoons (30 ml) olive oil
- 1 teaspoon (5 g) sea salt (adjust to taste)
- Optional seasonings: paprika, garlic powder, cayenne, or any favorite spices
Ingredient Notes

Kitchen Tools Needed
- Mandoline slicer or sharp knife
- Large mixing bowl
- Baking sheets (2 for even cooking)
- Parchment paper (optional)
- Silicone spatula or tongs
Step-by-Step Instructions
- Preheat your oven to 400°F (200°C).
- Wash and peel the sweet potatoes. Using a mandoline slicer or sharp knife, cut them into very thin slices, about 1/8 inch thick.
- Place the sweet potato slices in a large mixing bowl. Drizzle with olive oil and sprinkle with sea salt. Toss gently to ensure even coating.
- Lay the sweet potato slices in a single layer on baking sheets lined with parchment paper. Ensure they are not overlapping; otherwise, they won’t crisp up properly.
- Bake in the preheated oven for 20-25 minutes, flipping halfway through, until they are golden brown and crispy. Keep a close eye, as they can burn quickly toward the end of baking time.
- Remove from the oven and let cool slightly on the baking sheets before transferring to a serving bowl. Enjoy!
Pro Tips
- If you want ultra-crispy chips, after cutting the slices, soak them in cold water for 30 minutes. This helps remove excess starch.
- Make sure to dry the slices thoroughly after soaking—moisture is the enemy of crispiness!
- For uniform cooking, choose slices that are even in thickness; using a mandoline helps achieve this.
- Experimenting with spices can lead to unexpected and delightful flavor profiles, so don’t hesitate to try different combos!
Common Mistakes
- Overcrowding the baking sheets: This inhibits crisping as slices will steam rather than bake.
- Not slicing thinly enough: Thicker slices will take longer to cook and might end up chewy rather than crispy.
- Forgetting to flip halfway through: This is essential for evenly cooked chips.
Variations
- Sweet and Spicy: Add a touch of brown sugar and cayenne pepper for a sweet, spicy kick.
- Herb-Infused: Toss with dried herbs such as oregano or thyme for an aromatic flavor.
- Cheese-Flavored: Sprinkle with nutritional yeast or freshly grated Parmesan for a cheesy twist.
Serving Suggestions
These sweet potato chips make an excellent snack on their own or can be paired with guacamole, salsa, or hummus for a delicious dip option.
Storage Instructions
Store any leftover chips in an airtight container at room temperature. They are best consumed within a few days for maximum crunch.
Reheating Tips
If you have leftovers that have lost their crispiness, reheat them in a preheated oven at 350°F (175°C) for about 5–10 minutes to restore their crunch.

Frequently Asked Questions
Can I use other types of potatoes?

While oil helps with crisping, you can experiment with a light spray of cooking spray for a lower-fat version.
How can I keep chips crispy?
Make sure they are fully cooled before storing, and use an airtight container. For extra crunch, you can place a paper towel in the container to absorb moisture.
