Preheat oven to 375º. Gather the ingredients. Cut chicken into small .5 inch -1 inch cubes. Be sure they are all the same size to ensure even cooking. Add the chicken cubes to a large bowl. Add 1 tablespoon olive oil and seasonings (including 1 tablespoon ranch seasonings) and mix well.

In another bowl, add the cubed potatoes, add 1 teaspoon oil, add in 1 tablespoon ranch seasonings and mix well. Add them to the baking dish and cook the potatoes in the oven for about 15-18 minutes or until they are partially baked.

In the same bowl as the seasoned chicken, add the diced bell peppers, diced broccoli, sour cream, mayo. Mix really well to ensure everything is coated in the mayo/sour cream.

Add the chicken mix casserole dish with the potatoes, toss it all together. Please note if you use different sizes of baking dishes it will affect the cooking time, you will need to check the chicken to see if it's at temp throughout the process.

Loosely cover the casserole with tin foil. Place the chicken mix in the oven and bake for about 40-50 minutes. Pull the casserole out and check the chicken temp. If the chicken is cooked fully, sprinkle the cheese evenly across the casserole, pop it back into the oven, uncovered and bake for another 5-6 minutes to melt the cheese.

Let the casserole set for about 5 minutes and serve while hot! If you have juices at the bottom of the casserole, spoon the liquid over the casserole before serving.
