Dice the potatoes into uniform cubes for even cooking. Place them in a large mixing bowl and drizzle olive oil on top. Add paprika, garlic powder, salt, and pepper. Toss everything together until the potatoes are evenly coated.
Spread the seasoned potatoes in a single layer on a greased baking sheet. Pop them into a preheated oven at 400°F and roast for 35-40 minutes, flipping halfway through to achieve a crispy exterior.
Once the potatoes are done, sprinkle the shredded rotisserie chicken over them. The warmth of the potatoes will slightly reheat the chicken and infuse it with the roasted flavors.
Evenly distribute the shredded cheese, green onions, and bacon bits (if using) over the chicken and potatoes. Return the tray to the oven for 5 minutes or until the cheese melts into gooey perfection.
Take the baking sheet out of the oven, garnish with additional green onions (if desired), and serve this mouthwatering dish hot. Pair it with your favorite sauce, such as sour cream or ranch dressing.
