Homemade Spaghetti Sauce

In a large mixing bowl, add the canned tomatoes puree with an immersion blender. Blend until you reach your preferred texture. This can also be done in a food processor or blender.
Start by heating a large pot on the stove over medium-high heat. Add olive oil and sauté onions until they're softened, around 5 minutes.
2 Tablespoons Olive oil, 1 large white onion
Add in the garlic cloves and sauté for an additional 30-60 seconds. Then, add chicken broth, crushed tomatoes, tomato sauce, tomato paste, sugar, oregano, salt, pepper, basil, and parsley.
6 fresh garlic cloves, ½ cup chicken broth, 1 28-ounce can whole or crushed tomatoes, 2 8-ounce cans tomato sauce, 6 ounces tomato paste, 1 tablespoon white sugar, 1 tablespoon ground oregano, ¾ teaspoon kosher salt (if using table salt, add ½ teaspoon), ¼ teaspoon ground black pepper, 1 tablespoon dried basil leaves, 1 teaspoon dried parsley, A sprig of fresh basil
Bring the mixture to a simmer and cover to keep the moisture in. Lower the heat to a gentle simmer and let it cook for 1-4 hours.
