Homemade Marinara Sauce is super easy to make, and tastes so much better than jarred store bought sauce. Control the ingredients, and control the flavor!
In a large skillet, heat olive oil and cook the onions until soft (don't brown).
Add the garlic and cook for 30 seconds.
Add the tomatoes, tomato paste, spices, sugar and balsamic vinegar. Mix thoroughly.
Cover and simmer on low for 30 minutes.
If desired, use a blender or immersion stick blender.
Serve over pasta, or freeze in 2 cup portions.
Notes
What to do with leftoversStore in a covered container in the refrigerator for up to a week. Reheat until it is piping hot!Substitutions/AdditionsYou can use basil and oregano instead of Italian seasoning if you prefer. Those are the main ones, and you won't miss the other herbs from the premade seasoning.Red pepper flakes are great in this to spice it up and give it a little heat. Not necessarily traditional, of course, but I say you do you, boo.Freezing InstructionsLet sauce cool completely and transfer sauce to freezer safe airtight containers or freezer bags. This can be frozen for up to 6 months. When ready to use, thaw and reheat gently in saucepan at low heat.
