Homemade Italian Tomato Sauce Recipe - ready to use throughout the year with Pasta, Baked Dishes & our Favorite Italian Recipes!

Prep Time 10 minutes
Cook Time 2 hours
Water Bath Canning Processing Time (minimum) 35 minutes
Total Time 2 hours 45 minutes


  • 12 Cups Tomatoes (Cored, Peeled & Mashed)
  • 1/2 Cup Lemon Juice
  • 1/4 Cup Sugar
  • 2 Tbl (1/8 Cup) Oregano
  • 2 tsp Garlic Powder
  • 2 Tbl Garlic (minced) [Optional]
  • 2 tsp Onion Powder
  • 2 tsp Salt (Canning)
  • 2 tsp Black Pepper


  1. Prepare Tomatoes (*see Notes below) and place into a Nesco Roaster Oven or Large Stockpot.
  2. Add remaining ingredients to the Prepared Tomatoes and stir until well combined.
  3. Cover & bring Tomato Mixture slowly to a boil.
  4. Continue to cook at 250-300 Degrees until desired thickness. This may take @ 2 hours; checking every 30 min & stirring frequently to prevent sticking or scorching.
  5. Use Immersion Blender (or Food Processor/Blender in batches) to create a smooth sauce of desired consistency.
  6. Ladle the Italian Tomato Sauce into warm canning jars (Pint Jars work well) leaving a ½” headspace.
  7. Remove Bubbles from the Sauce by slowing sliding a bubble removing tool along the sides & middle of the Sauce. Wipe rims & side threads of the jars and place lid/ring on each jar, finger tightening the ring.
  8. Place jars into water bath canner for processing, making sure water covers the jars by an inch or two. The minimum processing time is 35 min; add time as necessary based on your altitude.
  9. Once processing is complete, let the jars sit in the water bath canner for about 5 minutes, then transfer to a towel/dish drying mat for 12-24 hours for cooling and sealing. Listen for the pings as they seal!
  10. After 12-24 hours, you can remove the rings, making sure the jars all sealed, label jars and place in a cool, dry place for storage. 50-70 degrees is optimal.
  11. If any jars did not seal, place them in the refrigerator for enjoying now!
  12. Enjoy this Versatile Italian Tomato Sauce as a Condiment or Sauce Base in your Favorite Italian Dish!


  • Tomatoes can be prepared for this recipe in a number of ways:
  1. Blanch, Core, Peel & Mash
  2. Using a Food Mill (place Cored & Quartered Tomatoes through a Manual, Sauce Master or KitchenAid Stand Mixer Food Mill Attachment)
  3. Frozen Tomatoes that have thawed in the Refrigerator overnight can easily be peeled by simply hand and then mashed in a bowl!

Tomatoes are SO easy to peel once thawed after being frozen & Prepping them for the freezer is a breeze as well! Simply place clean, ripe tomatoes into a freezer safe bag and store in the freezer until ready to do your food preservation project. When i’m going to do some tomato based canning, I then take the bag out of the freezer the night before & thaw the tomatoes in the refrigerator. Viola! Soft & easy to peel tomatoes are ready for your recipe!

You can Remove the Tomato Cores prior to Freezing as well to help make your Canning Day even more efficient!
