Canned tomatoes are a store cupboard staple for many UK households. They are versatile, convenient, and a cost-effective way to add depth and flavour to countless dishes, from hearty pasta sauces to warming winter stews. But with so many brands and varieties lining the supermarket shelves, choosing the best canned tomatoes can feel overwhelming. This comprehensive guide will delve into the world of canned tomatoes, exploring the different types available in the UK, the factors that influence their quality, and ultimately, help you discover the best options for your culinary needs.
Understanding the Different Types of Canned Tomatoes
The canned tomato aisle isn’t a homogenous sea of red. There are several distinct types, each offering unique characteristics suitable for different cooking applications. Understanding these distinctions is crucial for selecting the right product and achieving the best results in your recipes.
Whole Peeled Tomatoes
Whole peeled tomatoes are exactly what they sound like: whole tomatoes that have been peeled and preserved in tomato juice or purée. They offer a blank canvas for your cooking, allowing you to control the size and texture of the tomatoes in your final dish. They are often the best choice for recipes where you want a chunkier tomato presence.
Diced Tomatoes
Diced tomatoes have been chopped into small pieces before canning, offering convenience and saving you valuable prep time. They are ideal for sauces, stews, and casseroles where a consistent tomato texture is desired. Some diced tomatoes are also available with added herbs and spices, offering an extra layer of flavour.
Crushed Tomatoes
Crushed tomatoes provide a slightly smoother texture than diced tomatoes, offering a balance between whole and pureed. They are often used as a base for pasta sauces, pizzas, and soups, contributing body and richness.
Tomato Purée
Tomato purée is a concentrated tomato product made by cooking and straining tomatoes to remove the seeds and skins. It’s incredibly versatile and used primarily to thicken sauces, add depth of flavour, and enhance the color of dishes.
Tomato Paste
Tomato paste is an even more concentrated form of tomato purée, offering an intense tomato flavour and thickening power. A small amount of tomato paste can significantly enhance the richness and depth of sauces, stews, and soups. It’s also great for adding colour to dishes.
Factors Affecting the Quality of Canned Tomatoes
Not all canned tomatoes are created equal. Several factors influence their quality, impacting their flavour, texture, and overall suitability for various recipes. Paying attention to these factors will help you make informed choices and select the best possible canned tomatoes for your needs.
Tomato Variety
The type of tomato used in the canning process significantly affects the final product’s flavour and texture. San Marzano tomatoes, known for their sweet flavour, low acidity, and meaty texture, are often considered the gold standard. However, other varieties, such as Roma tomatoes, can also produce excellent canned tomatoes.
Origin and Growing Conditions
Where and how the tomatoes are grown can also influence their quality. Tomatoes grown in sunny climates with fertile soil tend to be sweeter and more flavourful. Look for canned tomatoes from regions known for producing high-quality tomatoes, such as Italy or Spain.
Processing Methods
The canning process itself can impact the quality of the tomatoes. Tomatoes that are processed quickly after harvesting tend to retain more of their flavour and nutrients. The quality of the canning liquid (tomato juice or purée) is also important. Avoid canned tomatoes with excessive amounts of water or added salt.
Acidity Levels
Tomatoes are naturally acidic, but the acidity level can vary depending on the variety and growing conditions. High acidity can result in a tart or sour flavour, while low acidity can lead to a bland taste. The best canned tomatoes strike a balance, offering a pleasant sweetness with a touch of acidity.
Additives and Preservatives
Some canned tomatoes may contain added salt, sugar, or preservatives. While a small amount of salt can enhance the flavour, excessive amounts should be avoided. Ideally, choose canned tomatoes with minimal additives and preservatives. Look for options labelled “no salt added” or “organic.”

Tips for Using Canned Tomatoes
Here are some tips to help you get the most out of your canned tomatoes:
-
Drain the excess liquid: Before adding canned tomatoes to your recipe, drain off any excess liquid. This will help to prevent your sauce from becoming too watery.
-
Adjust the seasoning: Canned tomatoes can vary in acidity and sweetness, so it’s important to taste your sauce and adjust the seasoning accordingly. Add a pinch of sugar to balance the acidity or a squeeze of lemon juice to brighten the flavour.
-
Simmer for longer: Simmering your sauce for a longer period of time will allow the flavours to meld together and deepen. This is especially important for pasta sauces.
-
Add herbs and spices: Don’t be afraid to experiment with different herbs and spices to create your own unique flavour profiles. Oregano, basil, garlic, and chilli flakes are all popular choices.
-
Store properly: Once opened, canned tomatoes should be stored in an airtight container in the refrigerator and used within a few days.
Exploring Recipes with Canned Tomatoes
Canned tomatoes are incredibly versatile and can be used in a wide range of recipes. Here are a few ideas to get you started:
-
Classic Tomato Sauce: Sauté garlic and onions, add whole peeled tomatoes (crushed), basil, oregano, and simmer for at least 30 minutes. Season with salt, pepper, and a pinch of sugar.
-
Hearty Tomato Soup: Sauté onions and carrots, add diced tomatoes, vegetable broth, and herbs. Simmer until the vegetables are tender, then blend until smooth.
-
Spicy Chilli Con Carne: Brown mince, add onions, garlic, diced tomatoes, kidney beans, chilli powder, cumin, and coriander. Simmer until the flavours have melded together.
-
Chicken Cacciatore: Brown chicken pieces, add onions, peppers, mushrooms, diced tomatoes, white wine, and herbs. Simmer until the chicken is cooked through.
Organic Canned Tomatoes: Are They Worth It?
Organic canned tomatoes are produced using tomatoes grown without synthetic pesticides or fertilizers. They may also be processed with fewer additives and preservatives. While organic canned tomatoes tend to be more expensive than conventional options, they offer several potential benefits.
-
Reduced Pesticide Exposure: Choosing organic canned tomatoes can reduce your exposure to potentially harmful pesticides.
-
Environmental Benefits: Organic farming practices are generally more sustainable and environmentally friendly.
-
Enhanced Flavour: Some people believe that organic tomatoes have a richer and more intense flavour.
Ultimately, the decision of whether to buy organic canned tomatoes is a personal one. If you are concerned about pesticide exposure or environmental sustainability, organic options may be worth the extra cost. However, conventional canned tomatoes can also be a safe and healthy choice.
Canned Tomatoes vs. Fresh Tomatoes: A Comparison
While fresh tomatoes are delicious when in season, canned tomatoes offer several advantages:
-
Convenience: Canned tomatoes are readily available year-round, regardless of the season.
-
Cost-Effectiveness: Canned tomatoes are generally more affordable than fresh tomatoes, especially out of season.
-
Consistency: Canned tomatoes offer a consistent flavour and texture, which can be helpful for recipes that require precise measurements.
-
Shelf Life: Canned tomatoes have a long shelf life, making them a convenient pantry staple.
-
Nutritional Value: Canned tomatoes are often processed at their peak ripeness, which can help to preserve their nutritional value. They are a good source of lycopene, an antioxidant linked to various health benefits.
Fresh tomatoes are best enjoyed during their peak season, when they are at their most flavourful. However, canned tomatoes are a convenient and versatile alternative for year-round cooking.
The Verdict: Choosing Your Ideal Canned Tomatoes
Selecting the best canned tomatoes ultimately depends on your individual needs, preferences, and budget. Consider the type of tomato, origin, processing methods, and additives when making your decision. Experiment with different brands and varieties to discover your personal favorites. Whether you opt for budget-friendly own-brand options or premium San Marzano tomatoes, canned tomatoes are a valuable tool for any home cook. Happy cooking!
What factors determine the quality of canned tomatoes?
The quality of canned tomatoes hinges on several factors. Tomato variety plays a crucial role, with San Marzano tomatoes often considered superior due to their sweet flavour, meaty texture, and low acidity. Furthermore, the processing method significantly impacts the final product. Tomatoes that are vine-ripened and quickly canned after harvesting retain more of their natural flavour and nutrients.
Another key consideration is the ingredient list. Look for cans containing only tomatoes, tomato juice, and perhaps a touch of citric acid or salt. Avoid cans with added sugar, preservatives, or other unnecessary ingredients, as these can mask the natural flavour of the tomatoes. Finally, the reputation of the brand and its commitment to quality sourcing and processing are good indicators of the final product’s excellence.
What are the different types of canned tomatoes available in the UK?
In the UK, you’ll find a variety of canned tomato products, each suited to different culinary applications. Diced tomatoes, also known as chopped tomatoes, are typically the most common and versatile option. Whole peeled tomatoes are ideal for sauces or stews where you want to break them down yourself. Then there are crushed tomatoes which are a smoother, more pulpy option for richer sauces.
Beyond these, you may also encounter tomato purée, a concentrated tomato paste with a thick texture, often used to deepen flavour. Passata is a smooth tomato sauce made from strained tomatoes, offering a silky texture. And finally, you can find sun-dried tomatoes in oil, a flavourful addition to pasta dishes and salads. Understanding the differences between these varieties is crucial for selecting the right option for your specific recipe.
Are San Marzano tomatoes really worth the extra cost?
San Marzano tomatoes are often pricier than other canned tomato varieties due to their superior quality and specific growing conditions. They are traditionally grown in the Agro Sarnese-Nocerino region of Italy, known for its rich volcanic soil. This region is what contributes to their distinctive sweet flavour, meaty texture, and lower acidity compared to standard canned tomatoes.
Whether they are worth the extra cost is ultimately a matter of personal preference and culinary application. For simple sauces or dishes where the tomato flavour is central, San Marzano tomatoes can make a noticeable difference in taste and texture. However, for complex recipes with many ingredients, the subtle nuances of San Marzano tomatoes might be less discernible, making a less expensive alternative a perfectly suitable choice.
How can I tell if my canned tomatoes are of good quality before opening the can?
While you can’t fully assess the quality before opening, certain indicators can suggest a good product. First, examine the can itself. Look for any signs of damage, such as dents, swelling, or rust. These can indicate that the can’s seal has been compromised, potentially leading to spoilage.
Secondly, check the expiration date to ensure the tomatoes are still within their recommended shelf life. Also, examine the ingredient list, aiming for a short list consisting primarily of tomatoes and tomato juice. Trusted brands that have a reputation for using high-quality ingredients and ethical sourcing practices can also offer a degree of assurance.
How should I store canned tomatoes once opened?
Once opened, canned tomatoes should not be stored in the original can. The acidic nature of tomatoes can react with the metal lining of the can, potentially leading to metallic taste and contamination. It’s always better to transfer remaining tomatoes immediately after opening.
Transfer the leftover tomatoes into an airtight container, preferably made of glass or food-grade plastic. Store the container in the refrigerator. Properly stored, opened canned tomatoes can typically last for 3-5 days in the refrigerator. Always discard any tomatoes that show signs of spoilage, such as an unusual odour or discolouration.
Can I use canned tomatoes as a substitute for fresh tomatoes?
Canned tomatoes can often be a convenient and excellent substitute for fresh tomatoes, especially when fresh tomatoes are out of season or lack flavour. Good quality canned tomatoes are usually harvested at peak ripeness and preserved quickly, locking in their flavour and nutrients. For sauces, stews, and soups, canned tomatoes can provide a richer, more consistent flavour than many fresh tomatoes.
However, keep in mind that canned tomatoes have already been cooked to some extent during the canning process. This can impact the final texture of your dish. For recipes where the texture of fresh tomatoes is desired, such as salads or salsas, fresh tomatoes are still the best choice. But for cooked applications, canned tomatoes are a reliable and flavourful alternative.
What are some common mistakes to avoid when cooking with canned tomatoes?
A common mistake is not tasting the tomatoes before adding them to your dish. Canned tomatoes can vary in acidity and sweetness, so tasting them allows you to adjust the recipe accordingly. If they are too acidic, add a pinch of sugar or a knob of butter to balance the flavour.
Another mistake is overcooking the tomatoes. While simmering tomatoes is essential for developing flavour, prolonged cooking can make them bitter. Avoid adding salt too early in the cooking process, as this can also intensify the acidity. Finally, don’t be afraid to experiment with different types of canned tomatoes to find the ones that best suit your taste preferences and culinary needs.
