Ingredients:
- 1 lb (450g) Spaghetti or Linguine
- 4 quarts (3.8L) Water
- 1 tbsp (15g) Salt
- 4 tbsp (57g) Unsalted Butter
- 3 cloves (15g) Garlic, minced
- 1 cup (100g) Parmesan cheese, finely grated
- 1 medium (50ml) Lemon, juiced and zested
- ¼ cup (60ml) Reserved pasta water
- 2 tbsp (8g) Fresh parsley, chopped
- ½ tsp (3g) Black pepper
Instructions:
- Bring the salted water to a rolling boil. Add the pasta and cook until al dente (usually 1-2 minutes less than package directions). Note: This ensures it doesn't overcook when tossed in the pan.
- Carefully scoop out ¼ cup of the cloudy pasta water and set it aside before draining.
- Place a large skillet over medium heat and melt the butter until it begins to foam.
- Add the minced garlic and sauté for 1–2 minutes until translucent and fragrant, but not brown.
- Stir in the lemon zest and cook for 30 seconds to wake up those citrus oils.
- Add the cooked pasta directly into the skillet.
- Pour in the lemon juice and the reserved pasta water. Toss vigorously over medium low heat until the liquid is glossy and reduced.
- Remove the pan from the heat entirely. Note: This is the most important step to avoid clumpy cheese.
- Stir in the finely grated Parmesan and chopped parsley, tossing until the sauce is creamy and coats every strand.
- Season with black pepper and serve immediately.
