Ingredients

Instructions

  1. Step 1: Heat 3 tbsp extra virgin olive oil in a large saucepan over medium-low heat. Add 3 minced garlic cloves and 1/4 tsp red pepper flakes, sautéing for 2 minutes until garlic is golden but not browned—do not let it burn.
  2. Step 2: Pour in 28 oz canned San Marzano tomatoes (crushed by hand), then add 1/2 tsp sea salt, 1/4 tsp black pepper, and 1/8 tsp pinch of sugar. Stir to combine and bring to a gentle simmer.
  3. Step 3: Reduce heat to low and cook uncovered for 45 minutes, stirring occasionally, until sauce thickens and coats the back of a spoon (it should reduce by 1/3).
  4. Step 4: Stir in 1/4 cup finely chopped fresh basil leaves and simmer for 5 more minutes until basil wilts and flavors meld. Taste and adjust salt or pepper if needed.
  5. Step 5: Remove from heat and let rest for 10 minutes before using—this allows flavors to deepen. Serve immediately over cooked pasta or with crusty bread.
