Characteristics
Roma tomatoes are oval-shaped, medium-sized tomatoes with a meaty texture and few seeds. Also known as Italian plum tomatoes, they are firm and have a lower water content compared to other varieties. Their dense flesh makes them ideal for sauces, soups, and canning.
In terms of size and appearance, Roma tomatoes usually range from 2 to 3 inches in length and are bright red with smooth skin. Their mildly sweet, slightly tangy flavor profile is ideal for dishes that require a concentrated tomato essence without excessive juice.
Origin and History
Despite their name, Roma tomatoes didn’t originate in Rome. In fact, they originated in Mexico and were first developed in the 1950s through agricultural breeding programs in the United States. Their popularity grew due to their resilience in cooking and suitability for preserving.
Culinary Uses
Roma tomatoes are prized for their versatility in the kitchen. Their low moisture content and rich flavor make them excellent for:
- Marinara and pasta sauces
- Tomato paste
- Salsas and chutneys
- Roasting or grilling
- They’re also great in salads when you want extra texture
Their firm flesh also holds up well during cooking, making them ideal for slow-cooked meals.
What Are Plum Tomatoes?

Characteristics
Plum tomatoes, like Roma, have an elongated shape but are often slightly larger. They have thick flesh, minimal seeds, and a robust, slightly sweet flavor. Plum tomatoes are sometimes referred to as paste tomatoes because they are often used to make tomato paste and canned products.
Their bright red color and balanced acidity make them a favorite among both chefs and home cooks.
Origin and History
Plum tomatoes are believed to have originated in South America, particularly Peru and Ecuador. They made their way to Europe in the 16th century, brought back by Spanish explorers. Originally used as ornamental plants, plum tomatoes later found their way into Mediterranean cuisine, especially in Italian dishes.
Today, they are cultivated worldwide, with Italy, Mexico, and the U.S. being major producers.
Culinary Uses
Due to their rich and slightly sweet flavor, plum tomatoes are commonly used in a variety of dishes:
- Tomato sauces and pastes
- Pizza toppings
- Bruschetta and crostini
- Grilled or roasted dishes
- Fresh salads
Their thick skin and flesh helps them maintain their shape during cooking, and their balanced sweetness enhances various recipes.

Comparing the Flavor Profiles
Roma Tomatoes
Roma tomatoes have a concentrated flavor that leans toward tangy but not overly acidic. This makes them ideal for slow-simmered sauces where a bold tomato taste is essential. Their subtle sweetness also complements herbs like basil and oregano beautifully.
Plum Tomatoes
Plum tomatoes are slightly sweeter and more aromatic, making them perfect for fresh preparations and recipes that highlight the natural tomato flavor. Their juicy interior and rich texture make them ideal for tomato juice, salad, or tomato-based drinks.
As someone who cooks with tomatoes almost daily, I’ve noticed that plum tomatoes give my bruschetta a richer mouthfeel, while Roma tomatoes are my go-to for any tomato-based stew.
Size and Appearance
Roma tomatoes typically range from 2 to 3 inches in length and are slimmer with a smoother surface. Their consistent size and firmness make them ideal for uniform slicing and dicing.
In contrast, plum tomatoes are usually larger, ranging from 2.5 to 4 inches, and may have a more pronounced point at the bottom. Their vibrant red color often stands out more due to higher lycopene content.
Beyond their physical differences, Roma and plum tomatoes also vary slightly in nutritional value.
