can diced or crushed tomatoes
Rich in lycopene, a powerful antioxidant, and vitamin C. Canned tomatoes are a good source of potassium and contain beneficial compounds that may be more bioavailable due to heat processing during canning.
About
Canned diced or crushed tomatoes are preserved tomato products made from ripe tomatoes that have been processed and sealed in metal cans for shelf stability. Diced tomatoes are cut into uniform chunks and packed in tomato juice or puree, while crushed tomatoes are finely ground or mashed into a coarse paste. Both are typically made from plum tomatoes (Roma varieties), which have fewer seeds and less water content than beefsteak varieties, making them ideal for processing. The canning process involves blanching, peeling, and heating to eliminate pathogens while preserving flavor and nutritional content. Many commercial varieties include added salt, citric acid (for preservation), and calcium chloride (for firming agents).
Culinary Uses
Canned tomatoes serve as foundational ingredients in countless savory dishes, particularly in Italian, Spanish, and Mediterranean cooking. They are essential in sauces (marinara, arrabiata, bolognese), soups (tomato bisque, minestrone), stews (chili, ragu), and braises. Diced tomatoes maintain their shape and texture, making them ideal for chunky sauces and dishes where visual texture matters; crushed tomatoes blend more smoothly, preferred for silky sauces and purees. Both forms eliminate the need for fresh tomatoes year-round and offer consistent flavor and acidity. They pair well with garlic, basil, oregano, onions, and olive oil, and are equally valuable in both meat-based and vegetarian preparations.
