  1. Preheat an oven to 400 degrees F (200 degrees C). Lightly grease a baking dish.
  2. Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Cook and stir the chicken and mushrooms until the chicken breasts in the hot oil until the chicken is no longer pink in the center and the juices run clear, about 15 minutes. Season with salt, pepper, and garlic powder and remove from heat. Stir in the zucchini, sweet potatoes, red potatoes, bread crumbs, Parmesan cheese, and 1/4 cup of olive oil; transfer to the prepared baking dish.
  3. Bake in the preheated oven, stirring every 15 minutes, until potatoes are tender and easily pierced with a fork about 1 hour.

I wasn't that impressed. It felt like something was missing something. I will not be making this again.

I hope you enjoy.

Wow-what a surprise. I don't (didn't) even like sweet potatoes but I loved this dish. My husband loved it as well. The only changes I made was that I added some red onion to it about half way th...

I really enjoyed this. I cut my potatoes rather small, and heated my baking dish in the oven while it was pre-heating as I wanted to hurry along the baking process. I halved the recipe and added...

Delicious, we will definitely be having this again. We are not fans of mushrooms, so I substituted dicesred bell pepper. The combination of colors made it look as good as it tasted. Thankyou ...

This recipe was awesome. My husband is usually not a casserole lover but he raved about it. The only thing I added was a diced onion and some minced garlic cloves. It was delicious and the house...

This was very good! I know I will be making this again. We made it a vegetarian meal, so no chicken. We didn't have mushrooms, and I don't like them anyway, so I omitted those too. However, I do...

I thought this was an excellent and unusual recipe. My husband doesn't like mushrooms, so I took the tip to substitute red pepper. We also added some chopped up onions, real garlic and extra b...

really good! added more bread crumbs and parmesan only because i like alot of each. i think that next time i will add more sweet potatoes - i like alot of those also.

I was skeptical but this was delicious! I halved (wish I hadn't) the recipe and only added some chicken seasoning to the chicken before cooking. So good, my husband wanted it a night later!
