Step by Step Method

Canning spaghetti sauce might look complicated, but if you follow these simple steps, you will find it quite easy. Let us go through the process from start to finish.

Step 1: Prepare the Tomatoes

Start by washing all the tomatoes carefully under clean running water. Remove any stems, leaves, or damaged spots. To peel them easily, fill a large pot with water and bring it to a boil. Drop a few tomatoes into the hot water for about 30 seconds, then take them out and place them in a bowl of cold water. The skins will slip off easily. Peel all the tomatoes this way and cut them into small chunks.

Step 2: Cook the Vegetables

In a large pot, heat the olive oil over medium heat. Add the chopped onions, garlic, carrots, and celery. Sauté them slowly until they become soft and fragrant. This step adds a deep, sweet flavor to your sauce. Stir occasionally to make sure nothing burns.

Step 3: Add the Tomatoes

Once the vegetables are tender, add the chopped tomatoes to the pot. Stir everything well. Allow the mixture to simmer on medium heat for about 30 minutes, stirring from time to time. The tomatoes will release their juice and begin to soften completely.

Step 4: Blend the Sauce

When the tomatoes are soft, use an immersion blender to make the sauce smooth. If you do not have one, you can transfer the sauce in batches to a blender, but be careful since it will be hot. Blend until you get a smooth consistency, then return the sauce to the pot.

Step 5: Add Herbs and Seasoning

Now it is time to give your sauce its delicious Italian flavor. Add the tomato paste, basil, parsley, oregano, thyme, sugar, salt, pepper, and red chili flakes. Stir everything well and taste to adjust the seasoning. Let the sauce simmer for another 45 minutes to 1 hour on low heat. The longer it cooks, the richer the flavor becomes. Stir occasionally to prevent sticking.

Step 6: Prepare the Jars

While the sauce is simmering, prepare your canning jars. Wash them with hot soapy water and rinse well. Place them in a large pot of hot water to sterilize for about 10 minutes. Keep the jars warm until you are ready to fill them. Also, place the lids in hot water (not boiling) to soften the seal.

Step 7: Fill the Jars

When the sauce is ready, ladle it carefully into the hot jars, leaving about 1 inch of space at the top. Add 2 tablespoons of lemon juice or a small amount of citric acid to each jar. This helps keep the sauce safe for long-term storage. Wipe the rims with a clean cloth to remove any sauce, then place the lids on top and screw the bands until they are fingertip tight.

Step 8: Process the Jars

Place the filled jars into a water bath canner. Make sure the jars are completely covered with water by at least one inch. Bring the water to a boil and process the jars for 35 to 40 minutes if using pint jars, or 45 minutes for quart jars. Keep the heat steady so the water remains boiling during the entire time.

Step 9: Cool and Store

After the processing time, turn off the heat and let the jars sit in the water for 5 minutes. Then carefully remove them and place them on a towel to cool completely. Do not disturb them while they are cooling. You will hear a popping sound as the lids seal, which means your sauce is safely preserved. After 24 hours, check the seals. If any lids did not seal properly, refrigerate those jars and use them within a week. Store the sealed jars in a cool, dark place for up to one year.

Extra Tips for Better Taste

Here are some helpful tips to make your spaghetti sauce taste even better and last longer.

1. Use the freshest tomatoes possible. Choose ripe and firm tomatoes with a bright red color. Avoid green or soft ones as they can make your sauce watery.

2. Add roasted vegetables. Roasting a few of the tomatoes, onions, or garlic before blending them gives a deeper and smokier flavor.

3. Do not skip the acid. Adding lemon juice or citric acid is very important for safe canning. It helps prevent bacteria growth and keeps your sauce shelf stable.

4. Simmer slowly. The longer you cook the sauce, the more the flavors develop. Be patient and let it thicken naturally instead of rushing the process.

5. Blend to your preference. Some people like a smooth sauce while others enjoy a bit of texture. You can choose how much to blend depending on what you like.

6. Add wine or balsamic vinegar for richness. A small splash of red wine or vinegar adds depth to the flavor without overpowering the sauce.

7. Label your jars. Always write the date and contents on your jars before storing them. This helps you keep track of freshness.

8. Store properly. Keep your jars in a cool, dark, and dry place. Avoid sunlight or humid conditions.

9. Try different herbs. Add rosemary, bay leaves, or even a touch of mint to create your own signature flavor.

10. Use the sauce creatively. Besides pasta, this sauce works beautifully on pizza, meatballs, casseroles, and baked vegetables.
