Boil the pasta in shallow water! Use less water than you would traditionally boil pasta in. This allows the water to become more starchy, which is perfect for a sauce like this.
1. Boil the pasta - make sure to reserve 1/4 cup of pasta water.2. Prepare the sauce - sauté garlic in butter then add lemon juice.3. Finish the pasta - add pasta, parmesan & pasta water to skillet. Toss.
