Turning Trash into Treats: The Best Upcycled Snacks You Can Make Today

Food waste is one of the world’s most pressing environmental issues. According to the United Nations, approximately one-third of all food produced globally is wasted each year. Not only does this waste contribute to landfill overflow, but it also represents a squandered opportunity to make better use of perfectly good food that could be transformed into delicious snacks. Enter upcycling—the process of creatively reusing discarded or overlooked food ingredients to make something tasty, nutritious, and eco-friendly.
1. Banana Peel Chips
Bananas are one of the most popular fruits worldwide, but did you know that banana peels are packed with fiber, vitamins, and antioxidants? Instead of tossing the peel in the compost, you can turn it into a crunchy snack. Banana peel chips are easy to make and require minimal ingredients.
Ingredients:
- 1 ripe banana peel (organic is best)
- 1 tablespoon olive oil
- ½ teaspoon sea salt
- Optional: chili powder, cinnamon, or garlic powder for flavor
Instructions:
1. Wash the banana peel thoroughly and cut off both ends.
2. Slice the peel into thin strips.
3. Toss the peel strips in olive oil, salt, and any additional seasonings you like.
4. Bake at 375°F (190°C) for 15-20 minutes or until crispy.
5. Let cool before serving.
These chips are not only delicious but also provide a savory alternative to traditional potato chips. You can customize the seasoning to suit your tastes, whether you prefer something sweet or spicy.
2. Potato Skin Crisps
If you’re a fan of baked potatoes, chances are you’ve thrown away the skin without a second thought. But potato skins are full of fiber and nutrients, making them the perfect base for a healthy, crunchy snack. Potato skin crisps are a great way to make use of leftovers from baked potatoes or mashed potato recipes.

Ingredients:
- Potato skins (from baked or boiled potatoes)
- Olive oil or melted butter
- Salt and pepper

Instructions:
1. Preheat the oven to 400°F (200°C).
2. If using leftover baked potatoes, carefully remove the skin, leaving a bit of the potato attached.
3. Brush the potato skins with olive oil or melted butter, and season with salt and pepper.
4. Place the skins on a baking sheet and bake for 10-15 minutes, until crispy.
5. Serve as a snack on their own or top with cheese for a savory treat.
These crisps are perfect for serving at parties or as a satisfying snack between meals. Plus, they’re a great way to reduce food waste while adding a crispy, savory element to your day.
3. Citrus Peel Marmalade
Citrus peels are often discarded after juicing or eating the fruit, but they’re actually packed with nutrients and essential oils. Instead of throwing away orange, lemon, or lime peels, why not upcycle them into a fragrant, tangy marmalade? This marmalade not only saves the peels from the trash but also offers a delightful spread for toast, yogurt, or pancakes.
Ingredients:
- 2 cups citrus peels (orange, lemon, or a mix)
- 1 cup sugar
- 1 cup water
- 1 tablespoon lemon juice
- Optional: a pinch of turmeric for color or spices like cinnamon or ginger for warmth
Instructions:
1. Wash and peel your citrus fruits, setting the fruit aside for another use.
2. Slice the peels thinly, removing any seeds.
3. In a pot, combine the citrus peels, sugar, water, and lemon juice.
4. Bring the mixture to a boil, then reduce the heat and simmer for 30-40 minutes, stirring occasionally.
5. Once the mixture has thickened to a jam-like consistency, remove it from the heat and let it cool before transferring to a jar.
This upcycled marmalade will keep for several weeks in the fridge and offers a great way to savor the natural sweetness and tang of citrus in a new form. It’s a perfect addition to breakfast spreads or as a topping for desserts.
