Ingredients

Instructions

  1. Step 1: Bring a large pot of salted water to a boil. Add 400g spaghetti and cook for 8-10 minutes until al dente. Drain, reserving 1/2 cup pasta water.
  2. Step 2: In a large skillet, heat 3 tbsp olive oil over medium heat. Add 6 minced garlic cloves and sauté for 30 seconds until fragrant. Add 4 tbsp unsalted butter and cook until melted, about 2 minutes.
  3. Step 3: Stir in 1/2 cup grated Parmesan cheese, 2 tbsp lemon zest, and 2 tbsp lemon juice. Cook for 2-3 minutes until the cheese is melted and the sauce is smooth, adding reserved pasta water as needed to reach a creamy consistency.
  4. Step 4: Add the cooked spaghetti to the skillet and toss to coat evenly. Season with 1/2 tsp salt and 1/4 tsp black pepper. Garnish with 2 tbsp chopped parsley before serving.
