A mandolin makes quick work of the slicing, since you will be cutting through a fair amount of cucumber. This keeps in the fridge for about a month once made.

Chef Jenn’s Take on Keto Pickles
The right cucumber matters more than people expect here. Skip the standard waxy cucumbers from the grocery store, they have big, tough seeds that are hard to chew and would need peeling anyway.
Use small cucumbers with few seeds instead. Baby English cucumbers from the grocery store work great, or look for small pickling cucumbers at a farmer’s market in early summer, my first choice when they’re in season. Trim the knobby ends, then use a mandolin to slice them into even 1/8-inch rounds, it makes quick work of what would otherwise be a lot of slicing.
The pickling method is the same as any quick pickle, dissolve the sweetener in the water and vinegar, add the mustard seeds, then let the liquid cool completely before adding the raw cucumber slices. Never cook them, the whole point is keeping that crunch.
If you don’t have mustard seeds on hand, skip them entirely or swap in celery seed instead. Add sliced onion or a bit of carrot too, for extra color and flavor. A sliced jalapeno turns this into a spicy, sweet, and tangy version if you want to switch things up.

These will be perfect in my veggie tray for the holidays. Great recipe!
Can’t believe you only need 5 ingredients for these yummy pickles!
We love pickles – they provide the perfect tangy snack! Definitely going to be giving this a try.
Such an easy recipe! Will try this, perfect because we love pickles! Thankssss
Question, I bought cucumbers today but forgot the Mustard seeds. Live in the country and can’t make a quick trip to the grocery store. Do you think it will make a big difference in the taste. If so, I will wait until next week and get the mustard seeds. TIA
No worries! They add a bit of flavor and some crunch but you can omit them. Or, if you have some celery seed, add that! You could also add some onion or even some carrot to jazz up the flavor and color a bit. Have fun experimenting and let me know how it turns out!

Your recipe calls for Mustard Seed, but your Amazon link takes you to Celery Seed. Which one please?
Hi Paul – mustard seed. The links were behaving oddly but they should be fixed now. Thanks for pointing this out! If you’re not inside the US, Amazon tries to be helpful with the links and will show you something similar if it’s not available locally.
I’ve been trying to learn about keto, but I had no idea pickles weren’t keto! This recipe looks great and I can’t wait to try them!
I had no idea it was so easy to make homemade pickles at home, and love that these are keto friendly too! I’m going to make them today and can’t wait to enjoy them on sandwiches and burgers soon!
