Boil a large, salted pot of water. Cook the pasta al dente according to package instructions.

When the pasta is 2-3 minutes away from being done, add the broccoli to the water.

Add the butter to a skillet over medium-high heat. Once melted, stir in the flour and cook for 1-2 minutes.

To the skillet, add the garlic, broth, lemon juice, and Italian seasoning. Let it bubble for a minute or so.

Whisk in the cream and let it cook for a few minutes until thickened to your liking. Stir in the parmesan cheese and remove from heat.

Drain the pasta and broccoli and add it to the skillet. If the sauce has thickened too much, add a small splash of pasta water prior to draining.

Season the pasta with salt & pepper as needed and serve immediately with extra parmesan grated on top if desired.
