While the slow cooker is running, combine the cream cheese, heavy cream, and Parmesan cheese; stir until the cheese melts and sauce becomes creamy.
Prepare the penne pasta as directed on the box, then put it aside to drain.
Toss the spinach into the slow cooker with the sauce and stir until it wilts.
After the pasta is done, add it to the slow cooker and stir until it is covered in the creamy sauce.
Warm up and savor!
Changes and Hints
Substituting half-and-half or, for a dairy-free alternative, coconut milk for the heavy cream will make this meal somewhat lighter. Sautéed bell peppers and mushrooms are great ways to increase the vegetable content. You could want to add some lemon zest on top before serving for a little more brightness. Tossing in some crispy bacon bits just before serving is usually a smart option if you’re looking to add some additional protein!
