The Best Tomatoes for Canning

There’s nothing better than opening a jar of homemade tomato sauce, salsa, or stewed tomatoes in the middle of winter and getting that fresh-from-the-garden flavor all over again. If you’re planning to preserve part of your harvest, choosing the right tomato varieties can make a big difference.

While any tomato can technically be canned, some varieties are much better suited for the job. The best canning tomatoes usually have thick walls, low water content, rich flavor, and fewer seeds. That means they cook down faster, create a thicker sauce, and give you more usable tomato in every batch.

What Makes a Tomato Good for Canning?

When you’re growing tomatoes for fresh eating, you may reach for juicy slicers, sweet cherry tomatoes, or colorful heirlooms. But for canning, texture matters just as much as flavor.

Tomatoes with low water content are ideal because they don’t release as much liquid when cooked. This helps sauces, pastes, and salsas thicken more quickly without needing to simmer for hours. A tomato with thick, meaty walls also gives you more substance and less waste, which is exactly what you want when filling jars.

Another helpful trait is a low seed count. Fewer seeds mean a smoother finished product, especially for sauces and pastes. While you can always strain or process your tomatoes, starting with a meatier variety makes the whole process easier.

Paste Tomatoes Are a Canning Favorite

Paste tomatoes are often the top choice for canning because they were practically made for it. These tomatoes tend to be oval or plum-shaped with dense flesh, fewer seeds, and less juice than slicing tomatoes.

They’re especially useful for:

Sauces
Salsas
Tomato paste
Stewed tomatoes
Roasted tomatoes
Freezing and preserving

Because paste tomatoes cook down so well, you’ll usually get a thicker, richer product with less time on the stove.

Flavor Still Matters

Just because a tomato is practical doesn’t mean it should be boring. The best canning tomatoes bring both structure and flavor. A good preserving tomato should have a rich, classic tomato taste that holds up well after cooking.

Some varieties lean sweet, while others have a deeper, more savory flavor. If you love homemade sauce, try growing more than one canning variety so you can blend flavors together. Mixing a classic paste tomato with a sweeter or more flavorful variety can give your sauce extra depth.

Can You Use Slicing Tomatoes for Canning?

Yes, you can use slicing tomatoes for canning, but they usually contain more juice and seeds. That means they may take longer to cook down and can create a thinner sauce.

If your garden is overflowing with slicers, don’t let them go to waste. They can still be canned, especially for crushed tomatoes, juice, or mixed sauces. But if you’re planting specifically for preserving, it’s worth making room for varieties bred with canning in mind.

Don’t Forget Salsa and Stewed Tomatoes

Canning isn’t just about sauce. Thick-walled tomatoes are also great for salsa because they hold their texture better after chopping. Watery tomatoes can make salsa runny, while meaty tomatoes help keep it chunky and flavorful.

For stewed tomatoes, paste and canning types also work beautifully. They keep their shape better during cooking and bring plenty of rich tomato flavor to soups, chili, casseroles, and winter meals.

Plan Ahead for Pantry-Filling Harvests

If canning is part of your garden plan, plant enough tomatoes to make the work worthwhile. It takes a good amount of fruit to fill jars, especially if you’re cooking tomatoes down into sauce or paste. Growing high-yielding canning varieties can help you get more from your garden space.

When harvest season hits, you’ll be glad you planned ahead. A few productive plants can turn into jars of sauce, salsa, and preserved tomatoes that keep your garden flavor going long after summer ends.

The Bottom Line

The best tomatoes for canning are flavorful, meaty, and easy to process. Look for varieties with thick walls, low water content, and fewer seeds for the best results. Whether you’re making sauce, salsa, paste, or stewed tomatoes, choosing the right tomato can make canning easier, faster, and more delicious.

Plant the right varieties now, and your future pantry will thank you.
