I don’t normally refer to any boneless skinless chicken breast dinners as decadent. I think that’s a hard feat to accomplish, friends.

While we love this lean protein for dinner and eat it frequently, it’s generally because it’s a somewhat light and healthy option that all of us enjoy.

This creamy, cheesy baked chicken and spinach? It’s decadent. It feels like something you’d eat at a restaurant, alongside a delicious swirl of pasta or on top of whipped potatoes.

Yes, it’s that good! Plus, it’s super low carb and made in just one dish. Who can argue with that? Not me… so it’s what’s for dinner! Let’s get started.

Tips

  • If your chicken breasts are large and thick, you can use a meat tenderizer to pound them more evenly.
  • Don’t crowd the chicken – it’s important to give it space for even cooking while it bakes.
  • For juicy chicken, allow it to rest 5-10 minutes before serving. This seals the juices in.
  • Use this printable meat temperature chart to ensure doneness.

    1. Hello!
      You can absolutely substitute with other types of chicken in this recipe, though your bake time will be a little different. Be sure to check the temperature of your chicken, as it’s finished cooking when the temperature reads 165°F.
      Enjoy!

    1. Hi Jackie,
      I do think you could try to just leave it out of this recipe! Common subs for sour cream are Crème fraîche, plain Greek yogurt, buttermilk and cottage cheese. We haven’t tested any of those subs in this recipe- but if you give one a try, please be sure to report back!
      Have a wonderful week,
      Julie
