How to Dice Tomatoes

Tomatoes are used in a seemingly infinite amount of recipes and often need to be diced. Dicing tomatoes is a quick, simple process anyone can master with some practice. Both Roma and regular tomatoes can be diced and then added to salads, soups, casseroles, and other dishes.

Dicing Regular Tomatoes

Tomatoes should always be washed under the faucet prior to dicing. Make sure to remove any dirt and debris. Peel off any stickers as well.
A small spoon or a teaspoon can be used to remove the core of your tomato. Simply insert the tip of the spoon into the tomato's stem. Dig out the stem using the spoon and then discard it.^{[1]XResearch source}

Cut the tomato in half. Hold the tomato with one hand and slice through it using a sharp knife. Start at the bottom of the tomato and cut it in two roughly even halves along the equator.^{[2]XResearch source}
- When cutting with a knife, cut with a sawing motion letting the blade do all the work. Do not force down the tomato.
4
Cut each half into slices. Place each half of the tomato on a cutting board with the flat part facing downward. Make a series of vertical cuts length-wise to make a series of thin strips. Strips should be no more than about a centimeter in length and should be roughly even in size.^{[3]XResearch source}
- As you cut, use your fingers to hold the tomato in place.
- Try to cut with a sawing motion, letting the blade do all of the work. This helps prevent you from squishing the tomato down!
Turn the strips sideways. Make vertical cuts across the strips, cutting the tomato into small, diced cubes. Strive to keep the space between cuts roughly even and use your fingers to hold the strips in place as you cut. When you're done, you will have a pile of diced tomatoes.^{[4]XResearch source}

Dicing Roma Tomatoes

Wash each Roma tomato under the faucet, turning it as necessary to wash the full surface and remove dirt and debris. If the Roma tomato has any stickers on it, make sure to remove these prior to dicing.
2
Remove the top. Near the top of a Roma tomato, there is a small stem. Cut off the end of the tomato with the stem so you're left with one flat end.^{[5]XResearch source}
- Some people don't bother cutting off the stem, as it's so small it's largely unnoticeable. If you don't mind the tomato stem, you can skip this step.
Cut the tomato length-wise to cut it in half. Cut it with one hand and hold it in place with the other. Try to keep the two halves of the tomato in roughly even sizes.^{[6]XResearch source}
4
Cut the tomato into vertical slices. Turn the two halves of your tomato sideways so you're cutting them length-wise. Make vertical cuts to cut the tomato into thin strips of roughly even sizes.^{[7]XResearch source}
- As Roma tomatoes are smaller than regular tomatoes, be careful when using your fingers to hold the tomato in place. Use only the tips of your fingers and be extra careful to keep your fingers away from the knife.
5
Dice the tomato slices. Turn your strips sideways and make a series of cuts running across the strips length-wise. This should cut your Roma tomatoes into small cubes. When you're finished, you'll be left with a pile of diced Roma tomatoes.^{[8]XResearch source}
- Strive to keep your cuts the same length so your diced tomatoes are roughly the same size.

Seeding Tomatoes Prior to Dicing

Make a cut down the center of the tomato. Try to keep the two halves roughly the same size.^{[9]XResearch source}
Make a series of three to four length-wise cuts across each half of your tomato. This should cut your tomato into quarters. Each quarter should be roughly the same size.^{[10]XResearch source}
3
Slice out the seeds. Place each quarter on a table or cutting board with the skin side facing downward. Slice a knife across the tomato to cut out the white, fleshy portion of the tomato. The seeds are attached to this portion, so they will be sliced out as well.^{[11]XResearch source}
- Sometimes, seeds linger on the tomato after you cut out of the fleshy portion. If any seeds did not come out, remove them with your fingertips.
Roma tomatoes are very small and delicate. They tend to have less seeds and the seeds can be difficult to remove without damaging the tomatoes. It's usually okay to leave the seeds of Roma tomatoes intact.^{[12]XResearch source}

Finished.

Question
How do I can dice Roma tomatoes to make tacos later?
Community Answer
Just cut them into slices, then lay those down and cut them into cubes until they are the size you want. If you want thicker ones you can just make thicker slices. Store in the fridge for a few hours until you're ready to make tacos.

Question
Can you use a food processor to chop tomatoes?
Community Answer
Yes, but you still need to cut them into quarters or larger chunks first. Don't leave the food processor on; instead, pulse it until the tomatoes are the size you want.

Question
Are tomato seeds safe to eat?
Community Answer
Yes, as long as you aren't allergic to them, don't mind the texture, and they havn't sprouted. If the seeds have sprouted, then you need to discard the entire tomato; sprouted tomato seeds are toxic.
