Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Boneless, Skinless Chicken Breasts: Use about 3-4 breasts depending on how many hungry mouths you’re feeding.
Mashed Potatoes: Prepare fresh or use store-bought; either works well in this recipe.
Cheddar Cheese: Grate fresh cheese for gooeyness; it melts better than pre-shredded cheese.

Fresh Garlic: Choose firm cloves for maximum flavor punch; garlic makes everything better.
Chicken Broth: Use low-sodium broth to control salt levels while keeping it flavorful.
Seasonings (Salt & Pepper): Always season your layers well; they need love too!
Green Onions: Chopped green onions add freshness and color to the final dish.
Butter: For richness; because why not indulge a little?

How to Make Mashed Potato Casserole with Chicken
Prep Your Ingredients: Start by preheating your oven to 375°F (190°C). Spray a 9×13-inch baking dish with nonstick spray so your casserole doesn’t stick like that last piece of tape on a roll.
Cook the Chicken: In a skillet over medium heat, cook diced chicken until golden brown and no longer pink inside—about 6-8 minutes. The aroma will be irresistible; consider yourself warned!
Create the Mashed Potatoes: Boil peeled potatoes in salted water until tender. Drain and mash with butter, sour cream, salt, and pepper until creamy perfection is achieved—think of clouds but tastier.
Layer It Up: Spread half of the mashed potatoes into the bottom of your prepared baking dish and layer cooked chicken evenly on top. Then cover with remaining mashed potatoes like you’re tucking them in for bed.
Add Cheese and Bake: Sprinkle shredded cheddar cheese generously over the top layer of mashed potatoes. Bake uncovered for 25-30 minutes until bubbly and golden—trust me when I say you’ll want to keep an eye on that cheese.
Add Final Touches: Once out of the oven, let it rest for about 10 minutes before serving. Top with chopped green onions for that pop of color—your guests won’t believe their eyes!
Now you have a deliciously comforting mashed potato casserole with chicken! Enjoy every cheesy bite surrounded by laughter and good company—it’s what food is all about!
