Ingredients You’ll Need

14 cups peeled Roma tomatoes: These are meaty and flavorful, ideal for salsa. If you can’t find Roma, substitute with San Marzano or other paste tomatoes for a similar texture.
3 cups onions, chopped: Yellow onions add sweetness and depth. You can use white or red onions if preferred.
1 red pepper, chopped: This brings a hint of sweetness to the mix. Feel free to substitute with a yellow or orange pepper.
1 green pepper, chopped: Adds a slight bitterness that balances the sweetness.
2 red hot peppers, chopped and seeded: Offers a punch of heat without overwhelming the flavor. Adjust the amount based on your heat tolerance.
4 jalapeño peppers, chopped (2 with seeds and 2 without): The seeds add extra heat, so customize these to suit your preference.
2 Thai chili peppers, chopped (1 with seeds and 1 without): For a uniquely spicy flavor, these little peppers pack a punch.
2 tablespoons minced garlic: Fresh garlic infuses aromatic goodness. Substitute with jarred minced garlic in a pinch.
4 tablespoons sugar: Balances acidity from the tomatoes and vinegar. Feel free to use honey or agave as a natural alternative.
2 teaspoons pickling salt: Specifically formulated for canning; it helps preserve the salsa. Regular salt can work, but avoid iodized salts.
1 teaspoon ground cumin: This adds warmth and an earthy depth. If you don’t have cumin, smoked paprika is a great substitute for a different flavor profile.
1 3/4 cups cider vinegar: Brings necessary acidity and tartness, ensuring safe canning. White vinegar can be swapped if desired.

How to Make Canned Tomato Salsa

Combine Ingredients: In a large pot, add 14 cups peeled Roma tomatoes, 3 cups chopped onions, 1 red pepper chopped, 1 green pepper chopped, 2 red hot peppers chopped and seeded, 4 jalapeño peppers chopped (2 with seeds and 2 without), 2 Thai chili peppers chopped (1 with seeds and 1 without), 2 tablespoons minced garlic, 4 tablespoons sugar, 2 teaspoons pickling salt, 1 teaspoon ground cumin, and 1 3/4 cups cider vinegar. Stir often and bring to a boil, then reduce heat to a gentle simmer.
Simmer Salsa: Allow the mixture to simmer for about 1 hour, stirring occasionally. This process reduces the salsa by half and thickens it. Adjust the taste by adding more salt if needed—this is your opportunity to make it just right!
Prepare Jars: Before finishing your salsa, put lids in hot water for 5 minutes. Then, pour your salsa into sterilized jars, ensuring to remove any air bubbles. Fill the jars to 1/2 inch headspace. Wipe rims carefully and seal with the lids.
Process Jars: Process the jars in a water bath. Cover them with at least 1-inch of water. Bring it to a rolling boil and process for 20 minutes (this increases based on the altitude: 25 minutes for 1,000-3,000 ft, 30 minutes for 3,001-6,000 ft, 35 minutes for 6,001-8,000 ft, and 40 minutes for 8,001-10,000 ft). Turn off the heat and let the jars rest in the hot water for 5 minutes before removing them.
Cool Jars: Shift the jars to a tea towel-lined counter and let them cool. Listen closely—those pops as they seal are music to any food enthusiast’s ears! If any jars don’t seal, simply place them in the fridge and use within a week.
Store Salsa: Canned salsa should be enjoyed within a year. Store it in a cool, dark place, and relish the flavors of summer no matter the season!

Storing & Reheating

To store your homemade canned tomato salsa, keep sealed jars at room temperature in a cool, dark place for up to a year. Once opened, refrigerate and consume within one week, ideally in an airtight container. If you want to keep it longer, you can freeze the salsa in freezer-safe containers for up to three months. When you’re ready to enjoy, simply reheat it on the stove over medium heat until warmed through. Note that the texture may change slightly, but you can refresh it with a touch more vinegar or fresh chopped cilantro for vibrancy.

Chef’s Helpful Tips

Ensure your jars are sterilized by boiling them in water for at least 10 minutes before pouring in the salsa.
Use fresh, ripe ingredients for the best flavor—overripe tomatoes or wilting peppers won’t deliver the same quality.
Adjust the types of peppers according to your heat preference, and always taste as you go to balance flavors perfectly.
If your salsa is too thick after simmering, you can add a little extra vinegar or water to reach the desired consistency.
To experiment, try adding a handful of fresh herbs like cilantro or parsley right before sealing the jars for a unique twist.
