Step 1: Preheat the Oven and Get Ready - Preheat your oven to 400°F. This gives you the perfect temperature to cook everything evenly while keeping the chicken tender.
Step 2: Season the Chicken with Flavor - In a bowl, season the cubed chicken with salt, black pepper, garlic powder, and ranch seasoning. Take a moment to mix it well so every piece gets coated. This step really builds the flavor from the start.
Step 3: Layer the Tortellini Base - Spread the refrigerated cheese tortellini evenly in a 9x13 baking dish. Try to keep it in a single layer so it cooks evenly.
Step 4: Add the Chicken Evenly - Place the seasoned chicken pieces over the tortellini. Spread them out so they cook evenly and do not clump together.
Step 5: Pour Over the Creamy Sauce - Pour the Alfredo sauce over everything, followed by the milk. Use a spoon if needed to gently spread it so all the tortellini is coated.
Step 6: Sprinkle in the Bacon - Add the cooked and crumbled bacon evenly across the top. This makes sure every bite gets that smoky flavor.
Step 7: Cover for Even Cooking - Cover the dish tightly with foil. This is important because it traps the steam and helps the tortellini cook perfectly in the sauce.
Step 8: Bake Until Tender - Bake for 25 minutes. During this time, the chicken cooks through and the tortellini softens as it absorbs all that creamy goodness.
Step 9: Add Cheese and Finish Baking - Carefully remove the foil and sprinkle the shredded mozzarella cheese over the top. Return the dish to the oven and bake for another 5 minutes until the cheese is melted and bubbly.
Step 10: Garnish and Serve Warm - Remove from the oven and sprinkle with chopped parsley. Let it sit for a few minutes before serving so everything settles nicely.
