If you’re dividing a recipe and it calls for one egg what do you do? Downsizing recipes for our toaster oven, I run into this problem a lot. Sometimes using only the egg white or the yolk is a good option. 

But more often than not, the recipes where I use part of a beaten egg (like these toaster oven chocolate chip cookies) end up tasting the most like the original larger recipe I’m trying to replicate.

Since I know that many of you are interested in resizing your own recipes, I thought it might be helpful if I shared how I measure half an egg (plus a few other smaller amounts).

How to Measure Half an Egg 

Start by cracking the egg into a container with a lid. I like to use a small mason jar.

Next, grab a fork or whisk and beat the egg lightly until the white and yolk are combined, about 30 seconds to 1 minute. 

Now, you’re ready to measure. 

How Much Does a Large Egg Weigh?

While each egg in a carton will vary slightly, in the US a standard large egg weighs about 57 grams in the shell and 50 grams measured outside of its shell.

How to Use a Digital Scale To Measure Half An Egg

So if a large egg measures about 50 grams, then half of a large egg equals about 25 grams.

  • Grab your mixing bowl and place it on a scale. (We use our little Ozeri Digital Scale)
  • Tare it out to zero. 
  • Measure out half of the egg (25 grams) into the bowl. 

How Many Tablespoons are In a Large Egg?

There are about 3¼ tablespoons in a large egg. To make things easy we’re going to round this number down to 3 tablespoons even.

How to Measure Half an Egg Using Tablespoons 

So if a large egg yields 3 tablespoons of egg, then half of a large egg = 1½ tablespoons. This can also be said as 1 tablespoon + 1½ teaspoons.   

I have a 1½ tablespoon measuring spoon that’s my go-to for this task. But you don’t need a special measuring spoon. Before I owned that handy spoon I’d just use a regular tablespoon and eyeball the 1/2 amount.

Partial Egg Measurements 

If you’re trying to reduce a recipe by 1/4 or 1/3 its size, the amount of egg needed will be different. Below is a list of mini measurements I use that you might find handy. (*Measurements have been rounded down.)

  • 1 Large Egg =  50 grams or 3 tablespoons
  • Half = 25 grams or 1½ tablespoons
  • Third = 16 grams* or 1 tablespoon 
  • Quarter = 12 grams* or 2¼ teaspoons
