Of course there are variations based on the size of the lemon and how juicy it is. This is the standard measurement based on the average juice of one lemon.

How Many Lemons Are Needed?

Have you ever come across a recipe that calls for a specific quantity of lemon juice and wondered how many lemons you need to buy? These lemon juice conversions should help!

  • 1 tablespoon lemon juice = 1/2 lemon
  • 3 tablespoons lemon juice = 1 lemon
  • 1/4 cup lemon juice = 1 1/2 lemons
  • 1/2 cup lemon juice = 3 lemons
  • 3/4 cup lemon juice = 4 lemons
  • 1 cup lemon juice = 6 lemons
  • 1 1/2 cups lemon juice = 8 lemons
  • 2 cups lemon juice = 11 lemons

Note: The number of lemons have been rounded up in cases where it would involve a strange fraction. For example, 1 average lemon = 3 tablespoons of juice so 1/2 cup lemon juice would equal 2.7 lemons. To make it easier, this was rounded up to 3 lemons since you will need to purchase 3 lemons in order to get that 1/2 cup of juice.

How To Juice A Lemon

There are plenty of tricks out there like heating up the lemon a bit or stabbing it repeatedly with a knife first (sounds a little psycho!). I jut like to keep things easy with the following method:

  1. Roll It: First roll the lemon on a cutting board or the counter using your palm. This helps to soften it up and maximize the amount of juice you get out of the lemon.
  2. Slice In Half: Slice the lemon in half crosswise.
  3. Squeeze: Squeeze the juice out of each half. Squeeze by hand or with the help of something like a hand-held juice press or citrus reamer.

Skewer Trick

This is a fun trick when you just need a bit of juice and don’t want to cut open the lemon. Roll the lemon first on the counter to soften it up. Then all you have to do is poke a hole in the non-stem end of the lemon with a skewer about an inch deep. Remove the skewer and squeeze a bit of juice out of the hole. Store the lemon in the fridge in a reusable food storage bag until you want to use it again.

How Much Zest Is In A Lemon?

One regular lemon yields about 1 tablespoon of lemon zest. However, most recipes that call for the “zest of 1 lemon” aren’t overly picky on the exact amount. I like to use a microplane grater to zest a lemon.

Tip: If a recipe calls for both lemon zest and juice, it’s much easier to zest the lemon first before you juice it.
