A Journey Through Time: The History of Diced Tomatoes
The story of diced tomatoes begins in the Andes region of South America, the birthplace of the tomato itself. Cultivated by the Aztecs and Incas, the tomato was a culinary cornerstone. When Spanish explorers brought tomatoes to Europe in the 16th century, they initially faced scepticism due to their association with nightshade. But as with many culinary adventures, this suspicion gradually morphed into appreciation, especially in Mediterranean cuisine. The Italians, in particular, embraced the tomato, recognizing its potential for deliciousness.
The advent of canning technology in the early 19th century was a game-changer for diced tomatoes. This innovative process allowed for the preservation and widespread distribution of tomatoes. It made them available year-round, breaking the seasonal barrier and making them globally accessible, turning them into the beloved kitchen staple we know and love today.
Mastering the Art: Cooking Techniques for Diced Tomatoes
Diced tomatoes are incredibly adaptable, lending themselves to a multitude of cooking techniques. From slow-simmered sauces to quick sautés, the possibilities are endless.
General Cooking Techniques
- Adding Early for Depth: Introduce diced tomatoes early in the cooking process when building flavour foundations for soups, stews, or pasta sauces. This allows their natural sweetness and acidity to meld with the other ingredients, creating a rich and complex taste.
- Adding Later for Freshness: For a brighter, more vibrant flavour, add diced tomatoes towards the end of cooking. This method is ideal for salsa, topping pizzas, or adding a fresh touch to a finished dish.
Specific Cooking Methods
How to Grill Diced Tomatoes
While not a traditional method, grilled diced tomatoes can add a unique smoky flavour to your dishes. Use cherry tomatoes (halved if large) and thread them onto skewers. Grill them briefly, turning frequently, until they develop a slight char. This adds a layer of complexity to your culinary creations. Alternatively, if you’re feeling adventurous, you can attempt to grill larger fresh tomatoes diced into similar-sized pieces for more even cooking and flavour enhancement.
How to Bake Diced Tomatoes
Baking diced tomatoes is a simple yet delicious technique, perfect for casseroles or fillings. You can bake them with other vegetables, proteins, herbs, and spices. Combine diced tomatoes with garlic, herbs like oregano and basil, and a drizzle of olive oil. Bake until the tomatoes soften, and the flavours meld. The result is a wonderfully aromatic and flavourful addition to your meal.
How to Sauté Diced Tomatoes
Sautéing diced tomatoes is a quick and easy way to create a simple sauce or side dish. Heat olive oil in a pan, add diced tomatoes, garlic, and your favourite herbs (basil, oregano, or thyme). Cook over medium heat until the tomatoes soften and release their juices. Season with salt and pepper to taste. This method is perfect for a quick weeknight dinner or a simple accompaniment to grilled proteins.
Ingredient Preparation: From Fresh Tomato to Culinary Delight
Whether you’re using canned or fresh tomatoes, proper preparation is key to maximizing flavour and texture.
How to Cut Diced Tomatoes
If you’re using fresh tomatoes, start by washing them thoroughly. The size and shape of your desired dice will determine how you proceed.
- For a Uniform Dice: Cut the tomato into even slices, then dice the slices into the desired size.
- To Core First: Depending on the tomato’s size, you can cut the tomato in half or quarters. You can also core the tomatoes before slicing.
- General Dicing: For general dicing, you may simply start slicing and dicing the tomato into the desired size.
How to Peel Diced Tomatoes
While peeling isn’t strictly necessary, it can improve the texture of some dishes.
- Score and Blanch: Use a sharp knife to score a shallow ‘X’ on the bottom of each tomato.
- Boil and Chill: Blanch the tomatoes in boiling water for 30-60 seconds, then immediately transfer them to an ice bath.
- Peel: The skins should now easily slip off.

How to Mince Diced Tomatoes
Mincing is usually not necessary for diced tomatoes, as the goal is to retain some texture. To achieve a finer chop, simply cut the tomatoes into even smaller pieces during the dicing process.
Preserving Freshness: Storage Solutions for Diced Tomatoes
Proper storage is essential to maintain the quality and longevity of your diced tomatoes.
Storage Guide
- Canned Diced Tomatoes: Store unopened cans in a cool, dry place. Once opened, transfer any unused portion to an airtight container and refrigerate. This preserves their freshness and prevents spoilage.
- Fresh Diced Tomatoes: Store fresh, diced tomatoes in an airtight container in the refrigerator for up to 3-5 days. For longer-term storage, you can freeze them.
Shelf Life Expectations
- Canned (unopened): Refer to the best-by date on the can, often several years.
- Canned (opened, refrigerated): Consume within 5-7 days.
- Fresh (refrigerated): Use within 3-5 days.
- Frozen: For optimal quality, use within 6 months, although the texture may change slightly.
Finding Alternatives: Substitutes for Diced Tomatoes
Sometimes, diced tomatoes are unavailable or not suitable. Fortunately, there are several excellent substitutes to consider.
- Tomato Passata: A smooth, strained tomato puree that provides a similar flavour profile.
- Fresh Tomatoes (diced): The most direct substitute, offering a fresher taste and texture, though requiring some preparation.
- Tomato Puree: Provides a thick, concentrated tomato flavour. Add liquid (water or stock) to achieve the desired consistency.
- Tomato Paste: An even more concentrated alternative to puree, requiring dilution with water or stock.
