Homemade Tomato Sauce & Crushed Tomatoes

I had a purpose for all of the tomatoes I bought last week.  I wanted to try homemade tomato sauce & crushed tomatoes that I frequently use for my homemade spaghetti sauce. The first step to either of these recipes is to prepare the tomatoes.  They need to be peeled of their skin and seeded.

The process of skinning the tomatoes is blanching and shocking.

Get a pot of boiling water and a bowl of cold water with ice.

  • cut an X in the bottom of each tomato
  • place 6-7 tomatoes in the pot of boiling water for about 30 seconds
  • remove the tomatoes from the boiling water with either a slotted spoon or tongs and immediately place in the bowl of ice water
  • after that the skins should slip right off of the tomato

The messiest part is seeding the tomatoes.  I cut them in half and pushed the seeds out with my fingers into a bowl.  Try to remove as many seeds as you can because they are pretty bitter.  After removing the seeds I wash the tomatoes and pour the bowl with seeds and juice over a strainer (with small holes) into another bowl, to gather the remaining juice (which is great for the sauce and the crushed tomatoes).

Crushed Tomatoes


  • peeled and seeded tomatoes (after trying the Roma tomatoes, I would recommend that you use either vine-ripened or beefsteak)
  • some extra tomato juice from the seeding process


Place tomatoes in food processor (as many as will fit).

Pulse food processor until you reach desired thickness.  I only did it a couple of times since I like them chunky. 

Measure out 28 oz. (large can size) or 15 oz. (reg. can size) portions and fill your freezer bags. 

Label them with what it is, amount you put in, and the date and lay them flat in the freezer. 

When they are frozen they will either stack or you can stand them upright in the door.

Tomato Sauce


  • 10 peeled and seeded tomatoes
  • some extra tomato juice from the seeding process
  • 1 large onion (diced)
  • 5 cloves garlic
  • 1/4 tsp pepper
  • 1/2 cup extra virgin olive oil
  • 4 TBS tomato paste


Heat oil on medium heat in medium sauce pan and put in diced onion and sweat it for about 25 min. (sweating means to place lid on pan and let the steam cook the onions through). 

Remove lid and grate in 5 cloves of garlic and let sit for another 5 min.

Add tomatoes, tomato paste, and pepper, stir together and let flavors blend on medium heat for another 10 min.

Let mixture cool fully before putting it into the food processor.

Blend in food processor and measure and put into freezer bags, again freezing them flat first.

There are many other recipes for tomato sauce if this one doesn’t work for you.  This happens to be the one my family likes best.
