Get the water boiling: Bring a large pot of generously salted water (like the sea!) to a rolling boil. This is key for flavorful pasta—don't skimp on salt!
Start the pasta: Add the spaghetti and cook according to package instructions until al dente—usually 8-10 minutes. Remember to reserve about 1 cup of starchy pasta water before draining.
Prepare the garlic: While the pasta cooks, thinly slice the garlic cloves. This ensures even cooking and beautiful flavor infusion without bitterness.
Heat the oil gently: In a large skillet or pan, pour in the extra virgin olive oil over medium-low heat. Let it warm slowly—this is where the magic begins!
Add the garlic and chili: Toss in the sliced garlic and red chili flakes. Stir gently and cook for 2-3 minutes until the garlic turns lightly golden and fragrant. Keep the heat low to avoid burning!
Infuse and bloom: The oil will become beautifully aromatic with garlic and spicy notes. If it starts to brown too quickly, lower the heat—patience pays off here!
Drain and combine: Drain the pasta, but save that precious pasta water! Add the hot spaghetti directly to the skillet with the garlic oil.
Toss with love: Using tongs, toss everything together vigorously. Add a splash (about ½ cup) of reserved pasta water to create a silky, emulsified sauce that clings perfectly.
Finish with freshness: Remove from heat, stir in the chopped fresh parsley, and give it another good toss. Taste and adjust salt or chili if needed.
Serve immediately: Plate the pasta hot, drizzle with a little extra olive oil, and top with grated Parmesan if desired. Buon appetito—enjoy every garlicky, spicy bite!
