Garden Fresh Tomato Sauce from Scratch

Homemade Pizza | Erica Robbin

My garden is looking good! Lots of tomatoes, especially the Roma and Husky cherry variety.

Having so many ripe, juicy, flavorful tomatoes reminds me of the times my grandma would make homemade tomato sauce for her oh-so delicious spaghetti sauce. She would make tons of it, freeze it in jars, ready for any occasion. It was so tasty and special when she would make her special spaghetti with it.

She would also say “it’s pretty easy” but I had never attempted to make it homemade myself until this week. So here is my version and like hers it uses fresh tomatoes, nothing from the can.

A lot of homemade sauce recipes call for added tomato paste or canned tomatoes, which is yummy as well, except when you want to make it garden fresh like my grandmother.

I found that roasting the tomatoes at two different stages in addition to a portion of fresh helps to give the sauce additional depth of flavor and a nice texture that can be adjusted for use as a pizza sauce or spaghetti sauce.

You can choose to leave it chunky or smooth, thin, or thick, sweet or less sweet.

Garden fresh tomato sauce for pizza or over any type of pasta!



  • 4-6 pounds vine ripened tomatoes, quartered with seeds and cores removed, Roma variety is best, but you can use any variety/combination, divided into thirds (light roast, heavily roasted, and fresh)
  • Drizzle olive oil
  • 3-5 cloves garlic, minced
  • 1-2 teaspoons granulated sugar (optional)
  • 1/4 to 1/2 white onion, finely chopped
  • 1-2 teaspoons oregano or Italian seasoning
  • 1-2 tablespoons chopped fresh basil
  • Salt and pepper to taste
  • Ground hamburger meat, cooked beforehand and set aside is also an option for spaghetti sauce


  1. Roast about 1/2 to 3/4 of the tomatoes in 400 degrees F (204 C) oven in two separate stages (15-20 minutes): lightly roasted and soft, the other with darkened skins.
  2. Puree fresh tomatoes and set aside. If you want a completely smooth texture, puree them all.
  3. In a shallow pan over medium heat, heat olive oil, then add garlic and cook for about 1 minute, then stir in sugar.
  4. Add onion and cook until just barely translucent.
  5. Add freshly pureed, lightly roasted, and heavily roasted tomatoes.
  6. Add oregano, basil, salt, pepper and cook down on low heat until desired texture.
  7. Add cooked hamburger meat for spaghetti if desired.

I inadvertently forgot to take a picture of the sauce by itself, so here it is on a pizza!
