Instructions
Cook the pasta until al dente in a large pot of well-salted boiling water, according to package instructions.
Add the broccoli florets for the last 1-2 minutes of cooking time, and cook until crisp-tender. Drain the pasta and broccoli, reserving ½ cup of cooking water, and set aside.
Meanwhile, melt the butter in a large skillet over medium-high heat. Add the shallot, Italian seasoning, and crushed red pepper flakes, and cook, stirring often, for 1 minute.
Add the garlic and flour and cook, stirring constantly, for 1 minute.
Slowly, continuously, whisk in the broth.
Stir in the heavy cream and lemon zest, reduce heat to medium-low, bring the sauce to a simmer, and then whisk in the Parmesan cheese.
Once the cheese is melted, whisk in the lemon juice. Taste and season with sea salt and freshly cracked black pepper.
Add the al dente pasta and broccoli to the sauce, and stir until well coated. Add some of the reserved cooking water if needed.
Remove the skillet from the heat. Taste and re-season if needed.
Serve immediately with lots of fresh Parmesan on the side. Enjoy.
