1largeonion, diced white or yellow, shallots work too OR 2 teaspoons onion powder
5garlic cloves, mincedOR 1 teaspoon garlic powder
1/2cupfresh basil leaves
1/2cup fresh parsley (optional)
1/4cup fresh oregano (optional)
2teaspoons sea saltstart with 1 teaspoon and add more as needed
1teaspoonsugar (optional) if your tomatoes are too acidic
Instructions
Bring several quarts of water to a boil in a large pot. Slice a shallow "X" in the end opposite the stem of the tomatoes. Drop in to boiling water until the skins just start to peel--about 30 to 45 seconds and transfer to a sink of cold water to cool slightly.
Peel away the skins, cut the core out and use your fingers to remove the seeds and pulp from the tomatoes. Place in a large bowl. If you are using canned tomatoes, open the can and use your hands to break up the tomatoes in to smaller pieces and set aside.
Transfer the tomatoes to a food processor and process until smooth or with very few chunks (process less if you want chunks). Set aside.
Chop the onions and garlic and set aside. In a large, heavy pot (not cast iron) heat the olive oil over medium heat 1 minute and add the onions and garlic. Sautee 1-2 minutes then add the tomatoes. They will be very watery and pale pink at this point. See Note 1 for when to use dried spices.
Add the basil and any other herbs if you are using them. Add 1 teaspoon of salt or start with a little less and stir to combine. Bring to a gentle simmer then reduce the heat to low. Stir constantly, 1-2 hours or until thickened to your preference. Taste after 1 hour and adjust seasonings as needed.
Notes
Note 1: If using onion and garlic powder: Heat olive oil, add tomatoes and then add powders with herbs and salt. Note 2: If using canned tomatoes, check for added salt. You will need to use less salt in your sauce if so.
