Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large saucepan over medium heat. Add 1 large chopped onion and cook for 5 minutes until translucent and soft.
  2. Step 2: Add 4 minced garlic cloves and cook for 1 minute until fragrant, stirring constantly to prevent burning.
  3. Step 3: Stir in 1 can (28 oz) crushed tomatoes, 1 can (14 oz) tomato puree, 1/4 cup chopped fresh basil, 1/4 cup chopped fresh parsley, 1 tsp sugar, 1/2 tsp salt, and 1/4 tsp black pepper.
  4. Step 4: Bring to a gentle simmer, then reduce heat to low. Cover and simmer for 45 minutes, stirring occasionally until sauce thickens and flavors meld.
  5. Step 5: If too thick, stir in 1/4 cup water, then simmer uncovered for 5 minutes until glossy and coat the back of a spoon.
