x 14½-ounce can diced tomatoes

ProduceYear-round. Canned diced tomatoes are available consistently throughout the year due to industrial processing and long shelf stability, making them a reliable alternative to seasonal fresh tomatoes.

Canned diced tomatoes are rich in lycopene, an antioxidant compound concentrated during processing, and provide significant amounts of vitamin C, potassium, and fiber. The canning process may slightly reduce vitamin C content but increases bioavailability of fat-soluble antioxidants.

About

Canned diced tomatoes are preserved tomato pieces prepared by harvesting mature tomatoes, washing, peeling, and dicing them before packing in a metal or steel can with tomato juice, citric acid, and salt for shelf stability. This product typically consists of a mixture of firm tomato chunks and a thickened liquid base, and represents one of the most standardized processed vegetable products in global commerce. The canning process involves thermal treatment to eliminate pathogens while preserving the nutritional profile and flavor characteristics of fresh tomatoes. Most commercial varieties are produced from determinate paste or slicing tomato cultivars bred for uniform size, color, and soluble solids content.

Culinary Uses

Canned diced tomatoes serve as a foundational ingredient across numerous cuisines, particularly in Italian, Spanish, Mexican, and Mediterranean cooking. They are essential to soups, stews, sauces, chilis, curries, and braises where they contribute both acidity and body. The pre-diced format and consistent quality make them invaluable for quick weeknight cooking, batch preparation, and professional kitchens. They integrate seamlessly into dishes where fresh tomatoes are unavailable or impractical, and the cooking process further develops their flavor profile through caramelization and concentration.

Forms & Preparations

Diced pieces in juice — Standard form with distinct 1/4–1/2 inch tomato chunks suspended in thickened tomato juice and seasonings, ready to use.
Fire-roasted — Tomatoes charred before canning to impart a smoky, caramelized flavor; used in Southwestern and grilled-style dishes.
No salt added — Unsalted version for recipes requiring sodium control or precise seasoning balance.
Organic — Canned diced tomatoes produced from organically-grown tomato cultivars without synthetic pesticides or fertilizers.
Italian style — Often includes garlic, basil, oregano, and olive oil in the packing liquid for enhanced seasoning.

Substitutes

Unknown — Use 1:1 by weight; fresh tomatoes release more liquid during cooking, so reduce other liquid in recipe and extend cooking time to develop flavor concentration.
Unknown — Use 1:1 by volume as a substitute; provides a smoother texture and faster breakdown; better for soups and sauces requiring uniformity.
Unknown — Use ¾ cup tomato sauce per 14.5 oz can; more concentrated, so add ¼ cup water per can to achieve similar consistency.
Unknown — Use 3-4 tablespoons diluted with 1 cup water per 14.5 oz can; concentrated product requires significant dilution but offers intense flavor control.
Unknown — Reconstitute with hot water and chop; use ¾ cup per can; produces a sweeter, more concentrated tomato flavor suitable for specific applications.
