Canned Spaghetti Sauce Recipe: Using Fresh or Frozen Tomatoes

Making your own spaghetti sauce can be incredibly satisfying and allows you to customize flavors according to your preferences. Whether you have an abundance of fresh tomatoes from your garden or a stash of frozen ones tucked away in your freezer, this easy-to-follow recipe will guide you through the process of creating delicious canned spaghetti sauce.

Why Home-Canned Spaghetti Sauce?

There’s something special about homemade spaghetti sauce. Not only is it a cost-effective alternative to store-bought versions, but it also lets you control the ingredients, ensuring that your sauce is as healthy as it is tasty. Canning allows you to preserve your creation for future use, making weeknight dinners more convenient.

Ingredients

Fresh Tomatoes

If you’re using fresh tomatoes, you’ll need about 10-12 pounds. Look for ripe, high-quality tomatoes like Roma or San Marzano for the best flavor.

Frozen Tomatoes

If you’re using frozen tomatoes, approximately 6-8 pounds of whole tomatoes will suffice. The freezing process will soften the tomatoes, making them easier to blend and cook.

Additional Ingredients

• 2 tablespoons olive oil
• 1 medium onion, finely chopped
• 4-5 cloves of garlic, minced (adjust to taste)
• 1 tablespoon sugar (optional, to balance acidity)
• 2 teaspoons salt (adjust to taste)
• 1 teaspoon black pepper
• 1 tablespoon dried oregano
• 1 tablespoon dried basil
• 1 teaspoon red pepper flakes (optional, for heat)
• 1 tablespoon of vinegar (balsamic or red wine), for depth of flavor
• Fresh herbs (basil or parsley) for garnish (optional)

Equipment Needed

• Large pot
• Canning jars (quart or pint size)
• Canning lids and rings
• Water bath canner or large stockpot
• Canning funnel (optional but helpful)
• Jar lifter
• Ladle

Instructions

Step 1: Prepare Your Tomatoes

Fresh Tomatoes:

1. Begin by washing the tomatoes and removing the stems.
2. Score the bottom of each tomato with a small ‘X’ using a knife.
3. Blanch them in boiling water for about 30 seconds until the skins begin to peel.
4. Immediately transfer the tomatoes to an ice bath to cool.
5. Once cooled, peel off the skins and chop the tomatoes into quarters.

Frozen Tomatoes:

1. Remove the tomatoes from the freezer and let them thaw slightly until they can be handled. Chop them into quarters, leaving the skins on (they’ll blend seamlessly later).

Step 2: Cook the Sauce

1. In a large pot over medium heat, add the olive oil and allow it to warm.
2. Add the chopped onion and garlic, sautéing them until the onion is translucent, about 5-7 minutes.
3. Stir in the chopped tomatoes (fresh or frozen) and bring the mixture to a simmer.
4. Allow it to cook down for about 30 minutes, stirring occasionally. The mixture will thicken, and flavors will meld.
5. Add sugar, salt, pepper, oregano, basil, red pepper flakes, and vinegar. Adjust seasoning to taste.
6. Simmer for an additional 10-15 minutes.

Step 3: Canning

1. While the sauce is simmering, prepare your canning jars by washing them in hot soapy water and rinsing well. Place them in a warm oven to sterilize.
2. Once the sauce is cooked, remove the jars from the oven and ladle the hot sauce into each jar, leaving about ½ inch of headspace.
3. Wipe the rims of the jars with a clean cloth to remove any sauce residue that may prevent a good seal.
4. Place the canning lids on each jar and screw on the rings until they are fingertip-tight.
5. Process jars in a water bath canner or large stockpot for 25-30 minutes. Ensure the water covers the jars by at least an inch.
6. After processing, carefully remove jars and let them cool on a clean kitchen towel or cooling rack. You should hear the satisfying ‘pop’ of the lids sealing.

Step 4: Enjoy!

Once cooled, store the jars in a cool, dark place. Your homemade canned spaghetti sauce will last for up to a year. The next time you need a quick and satisfying meal, simply open a jar, heat it up, and toss it with your favorite pasta!
