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
Okay, I was fully prepared NOT to like this recipe. I'm not a huge fan of cucumbers. But when our neighbor not so anonymously deposited about 3 lbs of cucumbers on our doorstep, and I had a potluck to go to, we made it.
We really liked them! Nice change from a salad. Wonderful!
These ARE delicious. I grew up on something similar, except that we didn't have the zing of the red pepper flakes. Nice addition. P.S. I totally covet that blue dish.
Oh yum! I have just recently started liking cucumbers, and this sounds so good. I'll have to pass this on to my mom; she LOVES cucumbers. In fact, you know her, Vicki Rasmussen. I'll tell her to call if she needs onions. 🙂
This looks delicious. I can't wait to try it.
Will someone please inform my garden that cucumbers actually need to grow? Thanks! They are still small plants. My garden is weird this year. Anyway, remind me where you are? Would love some onions! 🙂 Thanks for the recipe, looks yummy and kind of like the cuc salad from Noodles & co.
When you salt cucumbers are you supposed to rinse them afterward, or just leave the salt on them?
Made these last night, and they were AWESOME!!!
We eat these with Briyani rice in Malaysia. You can add pineapples and green apples too!
I've been munching on cucumbers with rice wine vinegar and a couple of shakes of Pico de Gallo seasoning. I'm definitely going to try this one – sounds yummy.
And I loved your opening story!
Really tasty. I thought I had more cucumbers from my CSA than I actually did, so substituted some red cabbage. So good with the red onion. I'm so happy to have this recipe:)
