Instructions

  1. Step 1: Bring a large pot of salted water to a rolling boil. Add 12 oz spaghetti and cook for 8-10 minutes until al dente, then drain and reserve 1/2 cup pasta water.
  2. Step 2: While pasta cooks, mince 3 garlic cloves and finely chop 1/2 cup fresh basil leaves. Heat 3 tbsp extra-virgin olive oil in a large skillet over medium heat.
  3. Step 3: Add minced garlic and cook for 1 minute until fragrant. Stir in 28 oz canned diced tomatoes, 1/4 tsp red pepper flakes, and 1/2 tsp sea salt. Simmer for 5 minutes.
  4. Step 4: Add the drained spaghetti to the skillet and toss to coat. Add 1/2 cup reserved pasta water and cook for 2 more minutes, stirring frequently until the sauce clings to the pasta.
  5. Step 5: Remove from heat and stir in 1/2 cup chopped basil. Serve immediately.
