Grandma's Homemade Spaghetti Sauce Recipe

This traditional spaghetti sauce from scratch recipe is so simple and easy that you will never need another! It has been passed down through the generations in my family, and it is a real winner! We've always made it using fresh tomatoes, but you can also use canned.

Equipment

Ingredients
  

  • 4 quarts tomatoes this is a volume, so use 128 fluid ounces if using canned tomatoes
  • 5 sweet onions chopped coarsely, divided
  • stalks celery chopped coarsely
  • ½ green pepper chopped coarsely
  • 6 cloves garlic pressed
  • ½ tablespoon oregano
  • 2 bay leaves
  • teaspoons basil
  • ½ tablespoon Italian seasoning
  • teaspoon crushed red pepper
  • ¼ cup sugar
  • 1 tablespoons salt
  • 9 ounces tomato paste
  • 16 ounces mushrooms sliced

Instructions
 

  • Blend tomatoes, half of onions, celery, garlic, and green pepper in blender to desired level of chunkiness. We like our sauce fairly smooth, so we blend ours for a good long while on the chop setting.
  • Transfer blended vegetables to a very large pot (at least 8 quarts). Add spices, tomato paste, mushrooms, and remaining onions. Cook for 3 hours, or until desired consistency is reached.
  • Remove bay leaves.
  • Preserve as desired. Makes 2 to 3 quarts.

Notes

This recipe makes 3 quarts of sauce. Nutritional information assumes a ½ cup serving.
