Ingredients:
- 2 cloves garlic, minced
- 1 tbsp unsalted butter
- 1/2 tsp red pepper flakes
- 1 cup heavy whipping cream
- 1/2 cup grated Parmigiano Reggiano
- 1/4 cup starchy pasta water
- 1/2 cup basil pesto
- 1/2 tsp lemon zest
- 1/4 tsp salt
- 1/4 tsp black pepper
Instructions:
- Melt 1 tbsp unsalted butter in a large skillet over medium heat until it bubbles.
- Add 2 cloves minced garlic and 1/2 tsp red pepper flakes. Cook for 1 minute until the garlic is fragrant and translucent but not browned.
- Pour in 1 cup heavy whipping cream and 1/4 tsp each of salt and black pepper.
- Bring the cream to a gentle simmer for 2-3 minutes until it slightly thickens and coats the back of a spoon.
- Lower the heat and whisk in 1/2 cup grated Parmigiano Reggiano. Adding cheese over high heat can cause it to become stringy.
- Slowly whisk in 1/4 cup starchy pasta water. Watch for the sauce to become glossy and smooth.
- Remove the pan from the heat and fold in 1/2 cup basil pesto. Residual heat is enough to warm the pesto without killing its bright color.
- Stir in 1/2 tsp lemon zest until the aroma of citrus is clearly noticeable.
- Toss your cooked noodles directly into the pan.
- If the sauce is too thick, add one extra tablespoon of pasta water at a time until it reaches a velvety consistency.
