Preheat oven to 400F
Place cauliflower florets on a parchment paper lined baking sheet, drizzle with oil, and add spices. Massage the oil and spices into the cauliflower and then bake for 20-25 minutes or until cauliflower has one side roasted dark
While the cauliflower is roasting, boil your pasta and start your sauce.
Once pasta is done boiling, drain it and set it aside.
To make the sauce, heat the butter on medium heat and add the minced garlic.
Once the butter and garlic start to sizzle, add the half and half. Bring to a low boil and add the flour. This step is really important. If you don’t add flour, you run the risk of the half and half curdeling when you add your lemon juice. Mix well, and lower the heat to medium low.
Once sauce starts to thicken, add in the lemon juice, water, and parmesan cheese. Mix well. You will see that the sauce is a little thicker now.
Turn off the heat, add your pasta and roasted cauliflower and mix.
Enjoy!
