It’s often hard to satisfy the craving for salty, crunchy snacks on a low carb diet (or any diet actually). This easy step by step process shows you how to make salt and vinegar veggie chips (using cucumbers in the recipe) in a dehydrator or in your oven set at low.

Dehydrator vs Oven-Baked
The dehydrator is basically just a low temperature oven which circulates the air throughout, so that the food dries evenly top to bottom and side to side (similar to a convection oven). The idea is to “slowly” remove moisture from foods, and crisp the food rather than “cook” it.
The advantage of a dehydrator is that it is easier to get consistency and you don’t have to worry about burning them or having the edges turn brown like in an oven.

The down side of a dehydrator vs the oven is time. It takes around 12 hours to dry chips in a dehydrator, compared to 3-4 hours in the oven. That means thinking ahead a bit when using a dehydrator. You don’t want to get up at 3 am to turn it off….like I did.
I find you can also moderate the exact temperature better in a dehydrator. I dry most everything at 135 degrees, which seems to be the sweet spot for crispy dried produce. This will vary of course, based on how thick you slice things, and how much water is in the produce.
So to summarize, I prefer the dehydrator because of the higher level of control over the final product. Time being the main down side.
Which is Best Dehydrator for Vegetables?
My favorite dehydrator is the American Harvest (aka Nesco brand, American Harvest). I have 4 of them now as we dry chile peppers and tomatoes on the farm for making our spice blends.
There are some that are not as expensive however. Many of the inexpensive ones work fine but they have limited temperature settings or they may not be flexible in the amount of trays you can add. So, if you choose a less expensive one, just make sure it has a temperature setting that you can control and think about how many trays you might want in the future.
The only one I would NOT recommend is one by Ivation. Mine broke after limited use and their customer service was abysmal.
Good used ones are fairly easy to find on local marketplace apps.
Using a Mandolin vs a Knife
One of the keys to successful salt and vinegar cucumber chips is consistency of the thickness. If you are extremely talented with a knife, you may be able to get consistent, thin slices. I personally am not that skilled with a knife.
The thickness of the slices will determine how long to dry the chips and how crispy they will become. A good mandolin allows you to set the thickness of the slices, and is much quicker than a knife (once you get it down).
There are many brands of mandolins, and some are very inexpensive. I like the French de Buyer Mandolin (photo below) because of the range of control you have over the thickness or thinness of the slices.
I also like it due to safety. It has legs which make it stable on the counter, and a knob that keeps your fingeres away from the very sharp blades.

The disadvantage of a mandolin is the cost. If you already have a knife and don’t want another kitchen tool, just make sure your knife is very sharp and keep your fingers away when slicing things thinly.
Other Low Carb Snacks to Make in Dehydrator
Once you get the hang of drying food, the preservation world really opens up. You can dry fruit, vegetables and even meat.
I grow and dry chile peppers and spices, which keep for a year and are much better than store-bought spices.
My daughter loves to dry vegetables. One of her favorites are these dried beet chips.
Try your hand with fruit roll-ups, jerkey, or dried berries. It’s a great way to make use of the food you grow yourself or pick up at the farmers’ market

Recipe for Salt & Vinegar Cucumber Chips
Salt and Vinegar Cucumber Chips
Equipment
Ingredients
- 2 Medium Cucumbers
- 1 Tbsp Olive oil
- 1 tsp salt or to taste
- 2 tsp Vinegar Apple cider vinegar or your favorite
Instructions
- Slice cucumbers very thin, trying to get consistent thickness so they will dry evenly. Use a mandolin slicer if available for best results. If you don’t have a mandolin, use a very sharp knife.2 Medium Cucumbers
- Pat cucumber slices dry with a paper towel to remove as much moisture as possible. Place cucumbers in fairly large bowl and add the rest of the ingredients. Toss together gently but thoroughly to combine.No need to let them soak in the brine, but don’t pat the brine ingredients off either. I used tongs to remove and place on dehydrator racks, letting the liquid drip off a bit.1 Tbsp Olive oil, 1 tsp salt, 2 tsp Vinegar
- For dehydrator: Place cucumber slices on trays and dry at 135°F for 12 hours or until they reach your desired crispiness (start checking them at 10 hours).For oven: Place slices on parchment lined baking tray. Dry at 175°F for 3-4 hours, checking every hour to ensure they don’t brown around the edges or burn. Turn them over half way through. Allow slices to cool before serving.

How long do you keep the slices in the brine ?

Good question Scott! We just left them in for a few minutes while getting the dehydrator ready. Pick them up with your fingers or tongs one by one to let the liquid drip off a bit and place them on the dehydrator rack. I changed the recipe directions to reflect this. Thank you for the question!

How thick do you slice the cucumbers? Could you give me a measurement please? Thank you. 😊

I slice them 1/8 to 1/4 inch thick. The thinner you slice them the quicker they will dry and the crisper they will be. Best……..

Can I overlap the cucumbers?
Dorothy Stainbrook
Saturday 8th of July 2023
I wouldn't. Cucumbers have a lot of water in them and the dehydrator needs to circulate the air around as much surface area of the cucumber as possible. You might end up with a cucumber chips that are only partially dried on the overlapping part which means they won't be as crisp and won't last as long.

I found that if you peel the cucumber it removed the bitterness. Great tasting after

Thank you for the tip! That would be especially important for older cucumbers with tougher skin.

I used a 3rd of the oil called for. Still turned out great. Have Ranch flavored cukes in the dehydrator now. I’ve won Best of Show at the Georgia National Fair w/ my dried pineapple slices, banana chips, & salsa. Won blue ribbon w/ my dried kiwi. If you like the vinegar flavor- try halved cherry tomatoes w/ a couple drops of balsamic vinegar & a flake or two of pink Himalayan sea salt in each half- then dehydrate. My son took them backpacking- a big hit

Thank you so much for the informative comment. And congrats for the blue ribbon! I do love the vinegar flavor and I happen to have a lot of cherry tomatoes so I’m going to try your suggestion this week.
