Fill your [Large Pot] with water and a generous handful of salt. Once it’s at a rolling boil, add the [Rigatoni pasta]. My little Olivia loves to watch the bubbles! Cook it for about 2 minutes less than the package says, we want it "al dente" so it finishes cooking in our yummy sauce.
While the pasta dances in the pot, heat [Olive Oil] in your [Deep Skillet]. Add the [Italian Sausage] and use your [Wooden Spoon] to break it into small, crispy crumbles. Let it get a deep golden brown; that’s where all the love and flavor lives!
Stir in the diced [Yellow Onion]. Cook until soft and translucent. Now, add the [Garlic] and [Red Pepper Flakes]. The kitchen will start smelling like Grandma’s house right about now! Let it cook for just a minute so the garlic doesn't burn.
Lower the heat and stir in the [Heavy Cream] and cubed [Cream Cheese]. This is Olivia’s favorite part, watching the white swirls disappear into the red sauce to make a beautiful pink. Stir until the [Cream Cheese] is completely melted and smooth.
Add the cooked rigatoni and the [Fresh Baby Spinach] into the skillet. Toss gently until the spinach wilts and the pasta is coated in glory. If it's too thick, add a splash of that reserved pasta water. Turn off the heat and stir in the [Parmesan Cheese].
