How to Cut a Grapefruit with Step-by-Step Instructions

A large and colorful citrus fruit, grapefruit packs a distinct flavor and loads of vitamin C. The taste of grapefruit is a mix of sweet, sour, and slightly bitter. They come in shades of yellow, pink, and red. In the U.S., grapefruits are cultivated in parts of Texas and Florida.

Thinking of adding some grapefruit to your weekly shopping list? You’ll need to know how to cut it. Here are 3 different ways to properly cut grapefruit and get the most out of your fruit. 

What do you need to cut a grapefruit?

Whichever way you cut your grapefruit, you’ll need a cutting board and a serrated knife. A serrated knife is best for cutting grapefruit because it requires less pressure to cut through the delicate flesh of the grapefruit. 

There is also such a thing as a grapefruit knife. This handy kitchen tool features a blade with a slightly curved tip, which conforms to the dome shape of a grapefruit half. This makes it easy to separate the pulp from the membrane, and scoop out the fruit whole or in sections. However, having a grapefruit knife is not essential.

How to cut a grapefruit

Cutting a grapefruit the right way will help you waste less of the fruit and make less of a mess. There are actually 3 tried-and-true ways to cut a grapefruit. Which one to use is mostly a matter of preference and desired presentation. 

How to cut a grapefruit in half

The first and most common method of cutting a grapefruit is to cut it in half and scoop out the sections as you eat them. You also cut your grapefruit in half to juice it.

Here’s how to cut your grapefruit in half to eat, step-by-step:

• Place the grapefruit on your cutting board.
• Position the grapefruit on its side (stem end pointing to the left or right).
• Cut the grapefruit through the middle, dividing the fruit into 2 halves.
• Use a steady sawing motion to carefully cut a circular path between the pulp and the rind. If you have a grapefruit knife, this is where you would use it. Otherwise, angle your knife slightly so that you match the curvature of the grapefruit.
• Use your knife to carefully slice between each section of fruit to more easily separate the pulp from the membranes. Don’t cut through the rind, just enough to free the pulp slightly.
• Repeat the steps above with the other half of the grapefruit.
• With all your tiny cuts made, you can now easily scoop out each section of grapefruit with a spoon and enjoy!

How to section a grapefruit with a knife

Cutting a grapefruit in half and scooping it out piece by piece is a great way to eat a grapefruit for breakfast—but what if you want to use your grapefruit in a salad or dessert? For a nicer presentation or working on a recipe, you will want to segment your grapefruit. This involves removing the rind completely and separating the pulp from the membrane to produce ready-to-eat sections of grapefruit.

There are 2 ways to section a grapefruit, the first method goes as follows:

• Position your grapefruit on the cutting board and slice off the top and bottom, exposing a little bit of the bright red flesh inside.
• Rotate the grapefruit so that one of the cut ends is flat against the cutting board. The flat cut surface provides a stable base to continue cutting the fruit. Otherwise, the fruit could easily roll or wobble while cutting, causing you to accidentally cut yourself. 
• Cutting from the top down, beginning cutting away the rind. Slowly work your way around the fruit, cutting the rind away in small pieces. 
• Carefully cut away any remaining pith. When you are done, you should be left with all red pulp.
• Next, you will cut the segments out one by one. To accomplish this, start by sliding your knife through 1 membrane, moving from outside of the grapefruit towards the center.
• When you get to the center, turn your knife back towards the outside of the grapefruit and slide your knife through the membrane on the other side of the segment you are working on. Pop out the grapefruit segment and set aside.
• Continue to cut out each section. In the end, you should be left with a clump of membranes, and a bowl full of beautiful and delicious grapefruit slices.

How to section a grapefruit by hand

You’ll still need a knife to section a grapefruit by hand. You’ll use it to get through the tough outer rind without tearing up the pulp inside. Sectioning grapefruit by hand takes a bit more time, but you will waste less pulp when removing the membrane carefully with your fingers. 

Follow these steps to section a grapefruit by hand:

• Start by scoring the skin of the grapefruit into 4 sections. Do this by scoring the skin into four equal sections. Don’t cut into the pulp, just deep enough to reach the pith.
• Peel away the skin of the grapefruit, one section at a time. When you are done, you should see nothing but pith.
• Gently the grapefruit apart with your fingers, separating into 2 halves. Pull apart each half to end up with 4 quarters total.
• Pick a quarter to start with. Cut a slit through the membrane that still surrounds the pulp, and set your knife aside. Put the tip of your fingers into the slit and start to peel away the membrane away from the fruit.
• When you’ve peeled enough of the membrane away, you will be able to easily pull the flesh out and move on to the next section. Discard the membranes and place your peeled grapefruit sections into a bowl. Continue in this fashion until you’ve finished breaking down the entire grapefruit.

Ready-to-serve cut grapefruit

There is nothing like freshly cut grapefruit. Try a grapefruit half with a little bit of sugar sprinkled on top. This brings out the natural sweetness while making the bitter flavor a bit more palatable for some. If you aren’t in the mood to cut your own grapefruit, you can also order ready-to-eat grapefruit from your local grocery. However you choose to enjoy your grapefruit, it is a tasty and nutritious addition to your regular shopping list.
