Cook pasta in a pot of generously salted water according to package instructions.
Heat butter in a large pan over medium-high heat. Add shallot and garlic and saute for 2 minutes, or until fragrant, stirring occasionally. Add shrimp and sprinkle with red pepper flakes and salt and pepper. Continue sauteing the shrimp for about 3-4 minutes, or until pink and no longer opaque.
Add the chicken stock, wine, lemon juice, and lemon zest, and stir to combine. Cook the mixture for an additional minute to boil down. Remove from heat.
Drain pasta and serve topped with the shrimp scampi. Sprinkle with parsley and parmesan.
