Ingredients

Instructions

  1. Step 1: Heat 3 tbsp extra virgin olive oil in a large saucepan over medium heat until shimmering. Add 4 minced garlic cloves and cook for 1 minute until fragrant—do not brown.
  2. Step 2: Add 400g crushed San Marzano tomatoes, 1 tsp salt, and 1/4 cup chopped fresh basil. Bring to a gentle simmer (180°F/82°C), then reduce heat to low and cook uncovered for 30 minutes, stirring occasionally until thickened and oil separates slightly.
  3. Step 3: Bring a large pot of salted water (1/4 cup salt per 4 quarts) to a rolling boil. Add 12 oz spaghetti and cook for 8-10 minutes until al dente, reserving 1/2 cup pasta water.
  4. Step 4: While pasta cooks, add 1/2 cup freshly grated Parmesan cheese to the tomato sauce and stir until melted and creamy.
  5. Step 5: Add drained spaghetti to the saucepan with 2 tbsp reserved pasta water. Toss vigorously over medium heat for 1 minute until sauce clings to noodles and coats the back of a spoon.
  6. Step 6: Serve immediately with extra basil leaves and Parmesan on top.
