Cook the Pasta: Bring a large pot of salted water to a boil. Add pasta and cook until al dente, about 8-10 minutes. Reserve 1 cup of pasta water, then drain.

Sauté the Garlic: Heat olive oil in a skillet over medium heat. Add garlic and sauté for 1-2 minutes until fragrant.

Create the Creamy Base: Pour in the light cream, stirring continuously for 2-3 minutes until it simmers.

Whisk in the Parmesan: Gradually add Parmesan, whisking until melted and sauce thickens, about 2-3 minutes.

Incorporate Miso and Lemon Juice: Add miso paste and lemon juice, stirring for 1-2 minutes. Adjust thickness with reserved pasta water if needed.

Toss the Pasta: Fold cooked pasta into the sauce until well-coated, adjusting with pasta water as necessary.

Final Touches and Serve: Season with black pepper and garnish with chopped herbs. Serve immediately.
