What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 8 oz spaghetti
  • 5 cloves garlic thinly sliced
  • 4 tbsp extra virgin olive oil
  • 0.5 tsp red chili flakes
  • 2 tbsp fresh parsley chopped
  • 0.25 cup grated parmesan optional

Step by step instructions

Step 1: Boil the Spaghetti

Cook spaghetti in a large pot of generously salted boiling water until just al dente. Reserve one full cup of pasta water before draining as you will need it for the sauce.

Step 2: Infuse the Oil

Heat olive oil in a wide skillet over medium-low heat. Add sliced garlic and chili flakes and cook very gently for 2 to 3 minutes until garlic turns lightly golden and fragrant. Watch carefully to avoid burning.

Step 3: Build the Sauce

Add half a cup of pasta water to the skillet and increase heat to medium. Let it simmer for one minute then add drained spaghetti and toss vigorously to create a glossy emulsified sauce.

Step 4: Garnish and Serve

Remove from heat and toss in fresh parsley. Plate immediately and add parmesan if desired along with an extra pinch of chili flakes for heat lovers.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • red chili flakes → fresh sliced red chili for a brighter heat or omit entirely for a mild version
  • parsley → fresh basil or chives for a different herbal finish

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Burning the garlic slices which makes the entire dish taste bitter and unpleasant
  • Not using enough pasta water to emulsify the sauce which results in oily spaghetti instead of a silky coating
