Ingredients

Instructions

  1. Step 1: Bring a large pot of salted water to a rolling boil. Add 400 g spaghetti and cook for 8-10 minutes until al dente. Reserve 1 cup pasta water and drain the rest.
  2. Step 2: While pasta cooks, heat 5 tbsp extra virgin olive oil in a large skillet over medium heat. Add 6 thinly sliced garlic cloves and 1 tsp red chili flakes. Sauté gently for 2-3 minutes until garlic turns golden and fragrant, careful not to burn.
  3. Step 3: Add the drained pasta to the skillet along with 1/2 cup reserved pasta water. Toss vigorously for 1-2 minutes to coat the spaghetti with the garlic-chili oil.
  4. Step 4: Remove from heat and stir in 1/2 cup freshly grated Parmesan cheese and 2 tbsp chopped fresh parsley. Season with salt and freshly ground black pepper to taste. Serve immediately.
