Preheat the oven to 400ºF. Line a baking sheet with parchment paper and set aside.
While the oven preheats, make your sauce. In a blender or food processor, pulse all sauce ingredients (cashews, coconut milk, broth, onion, garlic, ghee, and seasonings) until smooth.
Pat the chicken pieces dry, and lay onto the lined baking sheet. Season lightly with salt & pepper. Bake at 400ºF for 15 minutes.
Remove from the oven and add the broccoli to the pan, drizzling with the tablespoon of olive oil and sprinkling with salt & pepper to taste. Spoon the Alfredo sauce generously over the chicken (you can add some to the broccoli too, if you'd like!)
Return the pan to the oven, and continue baking for 15 more minutes. Broil for an additional 5 minutes at the end for some browning.
Serve hot, and enjoy!
