These Sweet and Spicy Cucumber Slices are tangy and sweet with a little bit of a kick. It makes a great side-dish for summer BBQ’s. There’s something incredibly refreshing about cold cucumbers, right? If you have an abundance of cucumbers coming out of your garden, then this recipe is especially for you. Aside from eating them plain, we love these on salads or added to lettuce wraps or just plain from the fridge. They’re unique and you have to make them to see why I love them so much!

Cucumber Slices
- Cucumbers – I am using standard garden cucumbers here (the variety most often sold in grocery stores) but feel free to use any variety you like.
- Kosher salt
- Rice vinegar – Also called rice wine vinegar. You can use plain or seasoned.
- Water
- Granulated sugar
- Red pepper flakes – Optional. Feel free to leave them out if you don’t like heat.
Equipment
- Mandolin – A mandoline will be your best friend here, but you can certainly slice by hand if you’d like. You can do peeled or unpeeled cucumber and you can leave them whole, or cut them in half. Your choice.


How to make Sweet and Spicy Cucumber Slices
- Slice cucumbers, place them in a colander and sprinkle with salt. Salting cucumbers draws out the moisture. If you don’t do this step, then all of this moisture will come out in the final dish and water it down. Place the colander in a pan to catch the drips and put the chole set-up in the fridge for a bit.
- While your cucumbers are draining you can prepare the simple marinade. Heat up rice vinegar, sugar, and red pepper flakes in a pan and after it’s reduced add some minced red onion. Honestly, you can leave out the pepper flakes if you don’t want any heat. These taste great sans pepper flakes as well.
- Pull your cucumber slices out of the fridge and pat dry. Transfer to a bowl and toss with the marinade.
- You’ll want to let these sit and marinate in the fridge for a while before you eat them. They get better with time, so give yourself at least a few hours chill time. They’re also great the next day, and even several days later. They become more like pickle-texture they longer they sit (which I like!).


Storing and Other Tips
- Store finished cucumbers in an airtight container in the refrigerator and enjoy within 3-5 days for best results.
- These cucumber slices are great as a snack right out of the fridge, as a side dish, or on top of a salad or lettuce wrap.
- From the comments section: Many people have used apple cider vinegar with success!

Frequently Asked Questions
Yes, feel free to make these using your favorite sugar substitute.
It’s usually not necessary to rinse the cucumbers, as the moisture being pulled out will take the salt with it as it drains. However, rinsing is always an option if you’re worried about it, or if you are using a strong salt, such as sea salt.

Sweet and Spicy Marinated Cucumbers
Equipment
- 1 Mandolin
Ingredients
- 1 ½ pounds cucumber about 3 medium, thinly sliced (peeled or unpeeled)
- 2 teaspoons kosher salt if using table salt, use only 1 teaspoon
- ½ cup rice vinegar seasoned or regular
- ½ cup water
- 3 tablespoons sugar
- ¼ tsp red pepper flakes optional if you don’t want any heat.
- 2 tablespoons minced red onion
Instructions
- Place cucumber slices in a colander sitting over a bowl, sprinkle with salt and toss well. Let sit for 1 hour refrigerated. Toss the cukes a few times while they drain if you remember. While cucumber slices are draining, prepare marinade.
- Combine vinegar, water, sugar. red pepper, and onion in a small saucepan; bring to a boil. Reduce heat, cook until reduced to a 1/3 cup (about 10 minutes). If for some reason you boil for too long, just add a little water until you have 1/3 cup. Remove reduction from heat and add onion. Let mixture cool to room temp.
- When cucumbers are done resting, pat them dry with a few paper towels and then combine with the vinegar reduction. Chill for at least a few hours before serving. They improve with time!
Notes
- Note: I have successfully made these with sugar substitute (like Truvia) as well.
- Tip: Sometimes I like to double the marinade to make them extra flavorful!
- Store finished cucumbers in an airtight container in the refrigerator and enjoy within 3-5 days for best results.












Questions & Reviews
My friend just emailed me a very similar recipe-it must be fate for me to make it, yum!!!
This looks great – thanks for sharing!
I made this last time and it was very delicious! I think the cukes I purchased were a bit too soft to begin with so they were a tad soggy today in the salad, but overall delicious. I broke off the plastic tab on the rice vinegar bottle and couldn’t open it, so I had to substitute apple cider vinegar instead.
I made these last night–so good they barely made it to the table!
In leu of the hot pepper flakes and sugar, I use Sweet Thai Chili sauce and a touch of Sesame Oil. (no cooking required.) Great summertime salad!!!
What is unique about rice wine vinegar..?
Another great tip on the cucumbers: if you de-seed them first (I use a teeny little spoon) and then salt them and let them sit for 20 minutes or so, it will completely get rid of the moisture in the cucumbers. (:
I was looking for a side dish to go with Asian Wraps and I came across this recipe. This recipe is so simple and delicious. I reccomend this recipe, indeed.
Just FYI: google cucumber kimchi. It’s very similar to this and extremely popular in Hawaii.
I ended up changing a lot of things to meet the ingredients I had. I ended up doing half cucumber and half zucchini. I was worried about the bitter of the zucchini but was happy with the sauces diversity that complimented it well. I ended up using balsalmic vinegar with a tad of honey and brown sugar with the white sugar and onions. Turned out fantastic!!!! Will make sure to get the original ingredients next time to try!
