Equipment

  • Canning Jars
  • Large Pot
  • Blender or Food Mill
  • Jar Lifter
  • Canning Lid and Bands

Ingredients
  

  • 10-12 pounds Roma tomatoes (or any other tomatoes)
  • 2 tablespoons Olive oil
  • 4 Garlic cloves, minced
  • 1 large Onion, finely chopped
  • 2 tablespoons Tomato paste
  • 1 tablespoon Dried oregano
  • 1 tablespoon Dried basil
  • 1 teaspoon Salt
  • 1/2 teaspoon Black pepper
  • 1 tablespoon Sugar

Instructions
 

  • Start by prepping your tomatoes. Blanch the tomatoes in boiling water for 1-2 minutes to loosen the skins. Peel the skins off, then chop the tomatoes into small pieces.
  • In a large pot, heat olive oil over medium heat. Add the minced garlic and chopped onions. Sauté for 5-7 minutes until the onions are translucent and the garlic is fragrant.
  • Add the chopped tomatoes to the pot along with tomato paste, oregano, basil, salt, pepper, and sugar. Stir well to combine.
  • Bring the mixture to a simmer and let it cook uncovered for 30-45 minutes, stirring occasionally, until the sauce thickens and the flavors meld together.
  • Use a blender or food mill to puree the sauce to your desired consistency. For a smoother sauce, blend for longer; for a chunkier texture, blend less.
  • Once the sauce is blended, return it to the pot and let it simmer for another 10-15 minutes to thicken further.
  • While the sauce is simmering, sterilize your canning jars by placing them in a pot of boiling water for 10 minutes.
  • Once the sauce is ready and your jars are sterilized, carefully ladle the hot tomato sauce into the jars, leaving about 1/2 inch of headspace.
  • Wipe the rims of the jars clean with a damp cloth, then place the canning lids and screw on the bands until they are fingertip tight.
  • Process the jars in a boiling water bath for 25-30 minutes. Make sure the jars are fully submerged in the water during processing.
  • After processing, remove the jars and let them cool. You should hear the lids pop as they seal. Once cool, store the jars in a cool, dark place for up to a year.

Notes

If you prefer a spicier sauce, you can add red pepper flakes or fresh chili peppers to the sauce while it’s simmering. You can also experiment with other herbs like thyme or rosemary for a more complex flavor.
