Roasted Redskins and Sausage Casserole

I make this recipe for a large group of people that I cook for on a regular basis and they seem to love it. I have to "up" the recipe sometimes for about 40 people but I also make it for the family in smaller portions. lol.. it's so easy. And I do like easy. 

Redskin Potatoes (or creamers)
Sausage or Kielbassi (your choice)
Fresh green onions
Olive Oil to drizzle
Basil
Onion Powder
Garlic ( I use fresh and Garlic powder)
Rosemary
Red Pepper Flakes
Paprika

Wash and cut up redskin potatoes, leave peels on. Boil for 15 minutes until tender. While the potatoes are boiling, cut the (already pre-cooked) sausage to bite size pieces. Drain the potatoes and pour all them into a baking dish. Drizzle or spray potatoes with Olive Oil. Then add bite size sausage. Season with all the seasonings listed. Chop up some green onions for added color and flavor. I use tons because I love them. I use the greens and very little of the actual onion part since it makes for a milder kick. Mix all the flavorings over the potatoes and sausage evenly. Some might like the potatoes a bit less "mashy" but I like them that way for a casserole so I kinda mash them a bit while mixing. I don't like hard potatoes in it. Put the casserole dish in the oven and bake covered for 20 minutes at 350*. Uncover to "crisp" sausage and top with more green onions in the last five minutes for looks  presentation. lol...
Note * If you don't like spicy then don't use the (Red Pepper Flakes) because they will cook up quite spicy with them!
