Preheat oven to 400 degrees F.

Place the asparagus in a shallow baking sheet and drizzle with olive oil, salt and pepper. Toss to coat. Place in preheated oven and roast for 20 minutes. Chop the spears into four equal pieces.

While the asparagus is cooking, cook your pasta according to package directions.

Place the butter, cream cheese, cream, milk and parmesan in a large, heavy saucepan and heat slowly to a low boil, stirring frequently. Once sauce is smooth, add lemon juice, zest and red pepper flakes. Simmer for a few minutes until the sauce thickens and becomes silky. Add a dash of black pepper.

Remove from heat and add the pasta and asparagus to the sauce and stir well to combine.

Serve and top with fresh, minced parsley.
