Even though tomatoes are an incredibly versatile ingredient, you may not know the best ways to cut them for different preparations. Plus, it can be easy to make a juicy mess if you’re using the wrong equipment or techniques.
This tutorial provides everything you need to know about how to cut tomatoes! Scroll through the post for step-by-step photos, followed by a short video.
How to Cut Tomato Slices
Use round tomatoes, like beefsteak or tomatoes on the vine, to make tomato slices. This is the best way to cut tomatoes for burgers and sandwiches.
- Use a serrated knife to cut off the end with the stem. Cut the rest of the tomato into slices of your desired thickness.
How to Cut Diced Tomatoes With and Without Seeds
Diced tomatoes are great for tacos and salsas. Roma tomatoes are the best variety to dice, since you can easily remove their cores and seeds to prevent your recipe from getting too mushy or watery. However, you can also cut slices from round tomatoes into cubes.
- Cut tomato slices from a round tomato. Stack a few of those slices on top of each other, then cut them into strips.
- Cut across the strips to make cubes.
- Slice each roma tomato in half lengthwise and then into quarters.
- Cut out the core and seeds from each quarter.
- Cut each quarter into thin strips.
- Dice the strips.
How to Cut Tomatoes into Wedges
Tomato wedges are great for salads. You can cut wedges that include the seeds or discard the seeds, depending on your preferences. I’m using an heirloom tomato in these photos, but you can use any round variety.
- Slice off the stem and cut the tomato into quarters.
- Cut each quarter into wedges of your desired size. Trim off pieces of the core or seeds if desired.
How to Cut Cherry or Grape Tomatoes
Cherry or grape tomatoes are great roasted or mixed into salads. You can leave them whole or cut them in half. If you need diced tomatoes and only have cherry or grape tomatoes on hand, you can cut them into quarters or smaller pieces.
- Use a serrated knife to cut the tomatoes in half or quarters.
Use a serrated knife to cut tomatoes. It’s a lot easier than cutting them with a regular knife. You need the scalloped edges to pierce the skin.
For big tomatoes, I use this serrated bread knife. For smaller tomatoes, I use the smaller version of the same serrated knife. If you’re in the market for good cutting boards that don’t slip, here are the bamboo cutting boards that I use.
How to Keep Cut Tomatoes Fresh
If you cut a slice or two from a round tomato, wrap it tightly in plastic wrap and place in the fridge for a few days to keep it fresh. Store diced tomatoes in an airtight container in the fridge for 3 to 5 days.
