Making the Asparagus & Bacon Chicken Potato Casserole is a smooth process. Follow these simple steps for a delicious outcome:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).
2. Prep the Baking Dish: Lightly grease a 9×13-inch baking dish with olive oil.
3. Cook the Potatoes: Boil the diced potatoes in salted water until just tender, about 10 minutes. Drain and set aside.
4. Sauté the Chicken: In a large skillet, heat a tablespoon of olive oil over medium heat. Add the cubed chicken, sprinkling with salt, pepper, garlic powder, and onion powder. Cook until browned and cooked through, about 5-7 minutes.
5. Add Asparagus: Stir in the chopped asparagus during the last couple of minutes of cooking to slightly tenderize it.
6. Combine Ingredients: In a large bowl, mix the cooked potatoes, chicken, asparagus, crumbled bacon, heavy cream, cheddar cheese, and half of the Parmesan cheese. Stir until everything is well coated.
7. Transfer to Baking Dish: Pour the mixture into the prepared baking dish, spreading it evenly. Top with the remaining Parmesan cheese.
8. Bake: Place the dish in the preheated oven and bake for 40-45 minutes or until the top is golden and bubbling.
9. Cool Down: Once baked, remove from the oven and let it cool for 10-15 minutes before serving. This allows the casserole to set up nicely.

This step-by-step guide will help you craft a delightful casserole that showcases the flavors of asparagus, bacon, chicken, and potatoes.
