Ingredients

Instructions

  1. Step 1: Heat olive oil in a large saucepan over medium-low heat. Add onions, carrots, and celery, and cook for 10 minutes until very soft and translucent, stirring occasionally to prevent browning.
  2. Step 2: Stir in garlic and cook for 1 minute until fragrant, then add crushed tomatoes, oregano, basil, sugar, and salt. Bring to a gentle simmer.
  3. Step 3: Reduce heat to low, cover partially, and simmer for 45 minutes, stirring every 10 minutes, until sauce thickens and flavors meld (allowing it to 'evolve' as per the dictionary definition).
  4. Step 4: Stir in fresh basil leaves and simmer uncovered for 5 minutes more until sauce coats the back of a spoon.
  5. Step 5: Cook pasta in a large pot of salted boiling water for 8-10 minutes until al dente. Reserve 1/2 cup pasta water, then drain pasta.
  6. Step 6: Toss drained pasta with 3/4 of the sauce in the saucepan, adding reserved pasta water 1 tbsp at a time until sauce clings to the pasta. Serve immediately with remaining sauce.
