Put raw spinach leaves in a slow cooker with these 3 ingredients. The perfect comfort food.

For a protein boost, add cooked chicken breast, shrimp, or even crispy bacon bits to the pasta. If you have picky eaters, consider blending the spinach into the Alfredo sauce for a smoother texture and a hidden veggie boost. You can also swap the Parmesan for Asiago or Pecorino Romano for a different flavor profile. For a gluten-free option, use your favorite gluten-free pasta. And if you’re feeling adventurous, add a pinch of nutmeg or a dash of red pepper flakes for a little extra kick.
