The natural sweetness of the potatoes combined with the savory flavor of red onions, all lightly coated with olive oil and baked to crispy perfection, offers a nutritious alternative to traditional fried chips. Let's dive into how you can prepare this simple yet delicious recipe at home.

Instructions:

1. Preheat Your Oven:
- Preheat the oven to 400°F (200°C) to ensure it's hot and ready by the time your ingredients are prepared.
2. Prepare the Sweet Potatoes:
- Rinse and scrub the sweet potatoes thoroughly. If you prefer, you can peel them, but leaving the skins on adds extra nutrients and texture.
- Cut the sweet potatoes into thin slices or rounds, about 1/4 inch thick, to ensure they become crispy when baked.
3. Prepare the Red Onions:
- Peel the red onions and cut them into wedges. Aim for 6-8 wedges per onion, ensuring that each piece is a similar size so they cook evenly.
4. Season and Oil:
- Place the sweet potato slices and red onion wedges into a large mixing bowl.
- Drizzle the tablespoon of olive oil over the vegetables. Toss everything together to ensure that the olive oil evenly coats all the pieces. You can use your hands or a pair of tongs for a thorough mix.
- Optional: Season with a pinch of salt, pepper, or any other preferred spices (like paprika, garlic powder, or thyme) to enhance the flavors.
5. Arrange on Baking Sheet:
- Spread the sweet potato chips and red onion wedges out in a single layer on a baking sheet. You may need to use two sheets or batch bake if there’s not enough space, as overcrowding will lead to steaming rather than roasting.
6. Bake:
- Place the baking sheet(s) in the preheated oven.
- Bake for about 25-30 minutes, turning halfway through, until the sweet potatoes are crispy and the red onions are tender and caramelized.
- Keep an eye on them towards the end of the baking time to prevent burning, as ovens can vary.
7. Serve:
- Once they are golden and crispy, remove the baking sheet from the oven.
- Let the sweet potato chips and red onion wedges cool slightly before serving.
8. Enjoy:
- Serve them as a tasty side dish, snack, or even a topping for salads and burgers.

There you have it - a straightforward and healthy way to enjoy sweet potatoes and red onions. This recipe not only brings out the natural flavors of the vegetables but also ensures a nutritious addition to your meal.
