How to Make Mashed Potato Casserole with Chicken
Preheat your oven to 375°F (190°C) and grab a trusty 9×13-inch baking dish. Spray it lightly with nonstick cooking spray to prevent any sticky situations later on.
Prepare your chicken by seasoning it generously with salt, pepper, and garlic powder. In a large skillet over medium heat, cook the chicken until golden brown—about 6-7 minutes per side—until those lovely juices run clear.
While the chicken cooks, whip up those mashed potatoes if you’re starting from scratch. Add butter and milk for creaminess while mashing until smooth and fluffy—think clouds but tastier.
Once your chicken has cooked through, let it rest for a few minutes before chopping it into bite-sized pieces. This allows the juices to settle in like they’re at their favorite spa retreat.
In your prepared baking dish, layer half of the mashed potatoes at the bottom like a cozy bed. Sprinkle half of the shredded cheese over them like confetti at a happy parade.
Now add all that beautiful chopped chicken on top followed by more cheese because who can resist? Finally, spread the remaining mashed potatoes over everything like a soft blanket before finishing with breadcrumbs for that irresistible crunch.
Bake in your preheated oven for about 30-35 minutes until bubbly and golden brown on top—the smell will have everyone racing into the kitchen!
Let it cool slightly before serving—you don’t want anyone burning their tongue because they couldn’t wait! Serve warm alongside fresh veggies or a crisp salad for a balanced meal.
This mashed potato casserole with chicken is not just food; it’s an experience that wraps you in warmth! Enjoy every bite!
