How to Make Moroccan Preserved Lemons with Sea Salt

Moroccan preserved lemons are so easy to make! This is the best way to preserve lemons, and the whole lemon is used. You only need two ingredients, lemons and sea salt. This recipe takes about 10 minutes to prep and four weeks of fermentation time.

What are Moroccan Preserved Lemons?

Cured lemons have long been a part of Mediterranean and Middle Eastern cooking, although most people associate them with North African, and particularly Moroccan cuisine.

Sometimes a plain squeeze of lemon juice on top of a dish is not enough, and that’s when we want to use preserved lemons. They add BIG flavor. The flavor can be described as highly citrusy, floral from the oils in the peels, and full of umami flavors from fermentation.

Preserved lemons add a fermented quality that regular lemons do not. 

Moroccan Preserved Lemons

Long ago, as lemon trees spread from Morocco to India, so did the want and need to preserve them. Originally, lemons were preserved for the same reason all things are preserved—to store and eat them even when they are out of season.

Before refrigeration, preservation almost always happened through salting and/or fermentation. The earliest recipe for preserved lemons is recorded in the 12th-century Egyptian treatise On Lemon, Its Drinking and Use, by the Arabic-speaking court physician Ibn Jumay.

Jumay’s 900-year-old recipe is almost exactly like the preserved lemon recipes we see today. According to Toby Sonneman’s Lemon: A Global History, the recipe calls for “slitting the fruit and filling the gashes with salt, then pressing them into a jar, covering with lemon juice and letting them ferment for weeks.” In this recipe, we follow similar methods.

The hardest part of this recipe is quartering the lemons without slicing them all the way through. It helps to cut the ends off the lemons so you can stand them flat on a cutting board to quarter them.

You want the quarters to stay attached on one end so that the lemons kind of open up like a flower to hold the salt.

This is the traditional historical recipe I’ve based mine off of… except I use weight measurements for consistency. Limes and grapefruits can also be preserved the same way, leading to all kinds of fun fermentation experiments and recipes this summer.

I plan to let mine ferment for a month; then they will keep in the fridge indefinitely. I’ll probably use them in salads and light, fresh meals on hot days this summer. I’d love to develop a Mediterranean lamb burger recipe that calls for preserved lemons. 

To use these fermented lemons, you can chop and use them as is for a source of lemon flavor and salt, or you can rinse the lemons. I mostly discard the pulp, then rinse the rind well to chop and use anywhere I’d use lemon zest.

It doesn’t take much fermented lemon to add a delicious bright lemon flavor to recipes.

How to Make Moroccan Preserved Lemons with Sea Salt

Moroccan preserved lemons are so easy to make! This is the best way to preserve lemons, and the whole lemon is used. You only need two ingredients, lemons and sea salt. This recipe takes about 10 minutes to prep and four weeks of fermentation time.

  • Author: Kaitlynn Fenley
  • Prep Time: 10 minutes
  • Fermentation Time: 4 weeks
  • Total Time: 672 hours 10 minutes
  • Yield: 32 Ounces
  • Method: Fermentation
  • Cuisine: Moroccan


  • 1300 grams fresh lemons (about 8 to 10 small lemons)
  • 250 grams sea salt
  • 2 extra lemons for juicing (if needed)


  1. Wash all of the lemons, and weigh out 250 grams of salt in a bowl
  2. Cut the ends off the lemons, then starting at one end, cut each lemon into quarters, without cutting all the way through (see photos above).
  3. Over a large bowl, fill the crevices of the lemons with copious amounts of salt.  Fill each lemon with salt until all the salt is used up.
  4. Start packing the whole lemons into a clean large jar. A quart mason jar worked well for me, but depending on the type of lemon you use, you may need a bigger jar. You will have to wedge them in as tightly as possible, and lemon juice will be released in the process.
  5. Once the jar is full make sure all the lemons are submerged in lemon juice. If you need to, juice two lemons and add the juice to the jar.
  6. Place a lid on the jar and allow the lemons to cure at room temperature for 4 weeks. You can allow the lemons to cure for up to a year at room temperature. They will darken the longer they cure.
  7. Once opened, store in the fridge indefinitely. Rinse off any excess salt and brine before using the preserved lemons in recipes. You can discard the pulp and use the well-rinsed rind anywhere that you’d use lemon zest.

When I was a kid my grandfather used to put salt on a lemon slice and eat it just like that. He taught me to do the same and it’s one of the most delicious things, and one of my fondest memories. I’ve never heard of preserved lemons before until Dec 2021 on our honeymoon trip and imagine my surprise when I found this recipe. This recipe is extremely easy to make and it’s absolutely delicious. Sometimes I’ll eat just a slice by itself because it’s just that good or when I’m feeling different I’ll chop up the pieces and put it in a salad. It’s refreshing and it adds that bit of acidity to a dish that you’re looking for. Try it! Cultured Guru coming through with the amazing recipes!

Joan August 7, 2022 - 7:05 pm

I followed the directions but have a lot of salt left in the big bowl. Is that expected?

Can I use oranges?

OK, I have done and weighed the lemons – I have 12 average size lemons. There is no way I could put them in a 32 oz jar. The juice alone was at the top so I had to put the rest of the lemons in another smaller jar.

That’s fine.

Some questions! I made this yesterday- I put all the extra salt in the jar. Added the juice of 2 extra lemons and everything was submerged. Today woke up and noticed the lemons floating up so the top few are no longer submerged. Do I open the jar and mash them down? Did I not add enough liquid?

It sounds like you have enough liquid if things are floating. My jar pictured here was so full and packed that nothing could float. You can open the jar and smash them down.
