Ingredients
- 4 oz (half of typical 8 oz package) spaghetti
- 3 tbsp extra virgin olive oil
- 4 cloves, thinly sliced garlic cloves
- 1/2 tsp red chili flakes
- 2 tbsp chopped fresh parsley
- 1/4 cup freshly grated Parmesan cheese
- 1 tsp for pasta water salt
Instructions
- Step 1: Bring a large pot of salted water with 1 tsp salt to a boil. Add 4 oz spaghetti and cook for 7-8 minutes until al dente. Reserve 1/2 cup pasta water and drain the rest.
- Step 2: While pasta cooks, heat 3 tbsp extra virgin olive oil in a large skillet over medium heat. Add 4 thinly sliced garlic cloves and 1/2 tsp red chili flakes, stirring frequently for 2-3 minutes until garlic is golden and fragrant but not burnt.
