A good marinara sauce recipe is a must in any kitchen. I use this one for everything from spaghetti to pizza and more.

3 tablespoons olive oil
6 cloves garlic, minced
1 medium onion, diced
1/4 tsp. crushed red pepper flakes
9 cups no salt added tomato puree
3 cups water
1 cup red wine or 1/4 cup balsamic vinegar (optional)
2 tablespoons sugar (optional)
1 1/2 tsp. salt
1 tablespoon dried oregano
1 tablespoon dried basil

Heat the olive oil in a large Dutch oven or stock pot over medium heat.

Sweat the garlic, onion, and crushed red pepper flakes until slightly softened and translucent, about 3-5 minutes. Add the tomato puree, water, and wine or vinegar (if using). Stir thoroughly. Add the sugar (if using), salt, oregano, and basil, mix, and allow the sauce to come to a boil. Reduce the heat to a simmer and cook for 30-40 minutes, stirring occasionally.
