Discover the secrets to crispy homemade veggie chips — beet and sweet potato style — that make for a healthy, guilt-free snack everyone will love.
There is a universal struggle when it comes to snacking: finding something that satisfies the craving for a savory crunch without derailing your health goals. We all know the disappointment of opening a bag of store-bought chips only to find it half-filled with air, laden with unpronounceable preservatives, and excessively oily. This is where veggie chips come to the rescue. Not only are they visually stunning with their vibrant purples and oranges, but they also offer a complex flavor profile that standard potato chips simply cannot match.
Making veggie chips at home allows you complete control over the ingredients. You dictate the salt level, the quality of oil, and the thickness of the slice. While it might seem intimidating to achieve that signature snap in a home oven, this guide covers everything you need to know. We are diving deep into the art of dehydrating and roasting root vegetables to create a snack that is nutrient-dense and incredibly addictive.
Why This Recipe Works
Many home cooks attempt vegetable chips only to end up with burnt edges and soggy centers. This recipe works because it addresses the number one enemy of crispiness: moisture. By utilizing a “sweating” technique before baking, we draw out excess water from the beets and sweet potatoes, ensuring they crisp up evenly.
Furthermore, the combination of beets and sweet potatoes is not just for aesthetics. Sweet potatoes have a high sugar content that caramelizes beautifully, providing a sweet counterpoint to the earthy, savory notes of the red beets. This balance makes these veggie chips a gourmet experience.
Finally, this method uses a “low and slow” baking approach. High heat often scorches the natural sugars in root vegetables before they dry out. By lowering the oven temperature, we essentially dehydrate the vegetables while roasting them, resulting in a chip that holds its crunch for days—if they last that long!
Ingredients
The beauty of this recipe lies in its simplicity. You don’t need a pantry full of exotic items to create the perfect snack.
- Red Beets: 2 large beets. Choose firm, round beets for uniform chips. Scrub them well; peeling is optional based on your preference for rusticity.
- Sweet Potatoes: 2 medium sweet potatoes. Look for ones with a similar diameter to the beets so they bake at the same rate.
- Olive Oil or Avocado Oil: 2-3 tablespoons. Avocado oil is excellent for its high smoke point and neutral flavor, but olive oil adds a nice grassy note.
- Sea Salt: 1 teaspoon coarse sea salt, plus more for the “sweating” process.
- Freshly Cracked Black Pepper: To taste.
- Optional Seasonings: Rosemary, thyme, or smoked paprika for a BBQ twist.
Equipment
To achieve the professional quality of store-bought veggie chips, having the right tools is half the battle.
- Mandoline Slicer: This is the most critical tool. Consistency is key to even baking. If one chip is thick and another is thin, one will be chewy while the other burns. Set your mandoline to 1/16th of an inch.
- Baking Sheets: You will need at least two large rimmed baking sheets.
- Parchment Paper: Essential for preventing sticking and easy cleanup. Do not use foil, as the veggies might stick or burn more easily.
- Paper Towels: A large quantity for drying the vegetables.
- Pastry Brush: Helpful for lightly coating the slices with oil rather than drenching them.
Step by Step Guide to Perfect Veggie Chips
Follow these steps meticulously. The difference between a limp vegetable slice and a crispy chip is in the prep work.
1. Prepare the Vegetables
Preheat your oven to 300°F (150°C). While the oven heats, wash and scrub your beets and sweet potatoes thoroughly. If you prefer a cleaner look, peel them, but leaving the skins on adds fiber and a rustic charm. Using your mandoline, slice the vegetables into uniform 1/16-inch rounds. Safety Tip: Always use the hand guard that comes with your mandoline!
2. The “Sweat” (Crucial Step)
Lay the slices out in a single layer on paper towels or a clean kitchen towel. Sprinkle them lightly with salt. Let them sit for 15 to 20 minutes. The salt will draw out the internal moisture, which will bead up on the surface. Pat them thoroughly dry with more paper towels. The drier the slice, the crispier the veggie chips.
3. Seasoning
Place the dried beet slices in a bowl and the sweet potato slices in a separate bowl (to prevent the beet juice from staining the potatoes). Drizzle with oil and toss gently with your hands to coat each slice evenly. You want a thin sheen, not a heavy coating. Add pepper and any other dry spices now.
4. Arrangement
Line your baking sheets with parchment paper. Arrange the slices in a single layer, ensuring they do not overlap. If they overlap, they will steam each other instead of roasting. You may need to bake in batches.
5. The Bake
Place the trays in the oven. Bake for 45 to 60 minutes. Halfway through (around the 30-minute mark), rotate the pans and flip any chips that are curling up significantly. Keep a close eye on them during the last 10 minutes; sweet potatoes can go from caramelized to burnt very quickly.
6. Cooling
Remove the chips from the oven. They might still feel slightly soft in the center—this is normal. They will crisp up significantly as they cool. Let them rest on the baking sheet or transfer to a wire rack for 10 minutes before eating.
To Incorporate With
These chips are fantastic on their own, but they shine when paired with the right dishes.
- Soup Side: Instead of crackers, serve these alongside a warm bowl of soup. They provide a satisfying crunch next to a creamy texture. Try pairing them with this creamy crack chicken soup for a cozy dinner.
- Charcuterie Boards: Add a pop of color to your cheese board. The sweetness of the beet chips pairs wonderfully with goat cheese or sharp cheddar.
- Sandwich Companion: Swap out greasy potato chips for these nutrient-dense alternatives next to your favorite club sandwich.
If you have a sweet tooth after your savory snack, these chips are light enough that you can still enjoy a treat afterward. Perhaps follow up with some keto peanut butter cups for a low-carb dessert option.

Tips for Success with Veggie Chips
Making veggie chips is an art form. Here are the expert tips to ensure consistency.
- Keep Colors Separate: Red beets are notorious for bleeding their color. Always prep, season, and bake them on separate areas of the tray (or separate trays entirely) from the sweet potatoes to keep the orange vibrant.
- Don’t Skip the Cool Down: It is tempting to eat them hot off the tray, but they are technically still “baking” as they cool. The molecular structure hardens as the temperature drops.
- Watch the Thickness: If you hand-slice, it is nearly impossible to get them thin enough. A mandoline is truly necessary. If you must use a knife, sharpen it immediately beforehand.
- Storage: Store in an airtight container at room temperature. If they lose their crunch after a day, pop them back in a 250°F oven for 5-10 minutes to revive them.

10 FAQ
1. Why are my veggie chips soggy?
This usually happens for three reasons: the slices were too thick, they were overcrowded on the pan, or you didn’t dry them thoroughly after sweating. Moisture is the enemy.
2. Can I use an air fryer?
Yes! Air fryers are great for veggie chips. Cook at 300°F for 10-15 minutes, shaking the basket every 5 minutes. You will likely need to do many small batches.
3. Are these healthier than potato chips?
Generally, yes. They contain more fiber and vitamins (like Vitamin A from sweet potatoes and folate from beets) and usually have less sodium and bad fats than processed chips.
4. How long do they last?
They are best eaten within 3 days. Store them in a sealed container or a Ziploc bag with the air squeezed out.
5. Can I use cooking spray instead of oil?
You can, and it will save calories, but the chips may feel a bit drier and less rich. A light brush of real oil usually yields a better texture.
6. Why did my sweet potatoes burn?
Sweet potatoes have high sugar content. If your oven has hot spots or the temperature is slightly too high, the sugar burns before the water evaporates. Try lowering the temp by 25 degrees and cooking longer.
7. Can I use golden beets?
Absolutely. Golden beets are slightly sweeter and less earthy than red beets, and they won’t stain your other vegetables.
8. Do I have to peel the vegetables?
No. The skin adds nutrition and helps the chip hold its shape. Just scrub them very well.
9. What prevents the chips from sticking?
Parchment paper is the best solution. Silicone baking mats also work well, but parchment allows for better airflow underneath.
10. Can I season them after baking?
It is best to season before baking so the flavors cook into the vegetable. However, a final dusting of salt right when they come out of the oven helps it adhere.
