When it comes to making really good homemade tomato sauce, I always turn to this incredible recipe because it’s so simple, so good and uses only three simple ingredient (fresh tomatoes, onions and butter!).

Fresh tomatoes are just so versatile, and there are endless incredible homemade foods you can make with them, like this easy homemade tomato juice, these oven sun dried tomatoes, and the best homemade ketchup.

How to Make Homemade Tomato Sauce

  • Prep the vegetables. Chop up the onion and tomatoes.
  • Cook. Saute the onion in butter over medium heat and then add the tomatoes.
  • Simmer for 30 minutes.
  • Prepare the food mill. Use a food mill that has been fitted with the disk with the largest holes. Set it over top of a pot. A food mill is a kitchen tool used for pureeing or grinding sauces or soups. I like it because it can be used for both hot and cold foods.
  • Puree. Transfer the tomato sauce (with any juices) to the mill and puree.
  • Season. Season with salt to taste and serve immediately.

While you might not be able to keep homemade tomato sauce in the refrigerator for very long, you can definitely still freeze it in order to extend the shelf life.

Once the sauce has completely cooled, you can then transfer it to either a freezer-safe, airtight container or bag. Frozen homemade tomato sauce can stay good for 3 to 4 months.

When you’re ready to reuse the leftover tomato sauce, I would recommend thawing it out overnight in the refrigerator first. To reheat it, simply warm it up over medium heat in a saucepan and add a splash of water if needed.
