This Mashed Potato Casserole is a crowd-pleasing, comforting dish that’s perfect for a weeknight dinner or a potluck.

It’s the kind of meal that warms you from the inside out and always leaves everyone asking for seconds. Let’s get started!

Cooking Instructions:
Step 1: Preparing the Chicken and Gravy Base
First things first, let’s get our chicken tenders ready. If you’re using frozen chicken tenders, follow the package instructions for cooking them. Typically, this involves baking them in the oven until they’re golden brown and cooked through. For homemade tenders, you’ll want to ensure they are fully cooked as well. Once your chicken tenders are cooked, set them aside. We’ll be slicing or chopping them later.
Now, let’s tackle the gravy. If you’re using a packet mix, prepare it according to the instructions on the packagin extractg. This usually involves whisking the powder with water or broth and simmering it on the stovetop until thickened. If you’re using pre-made gravy, simply heat it up until it’s warm and pourable. We want a good amount of gravy here, as it will help bind the casserole together and add a wonderful depth of flavor. Aim for at least 2 cups of prepared gravy. If it seems a bit thin, you can always simmer it for a few extra minutes to let it reduce and thicken.
Step 2: Assembling the Casserole Layers
Now for the fun part – building our delicious casserole! Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly grease a 9×13 inch baking dish. This will prevent the casserole from sticking and make for easier cleanup.
In a large bowl, gently combine your prepared mashed potatoes with about half of your cooked and chopped chicken tenders. We want to distribute the chicken evenly throughout the mashed potatoes. Add about half a cup of your prepared brown gravy to this mixture and stir gently until everything is well incorporated. Be careful not to overmix, as this can make the mashed potatoes gummy. The goal is to have a cohesive, but still fluffy, potato and chicken mixture.
Step 3: Adding the Corn and Cheese
Next, we’ll add another layer of flavor and texture. Spread this mashed potato and chicken mixture evenly into the bottom of your greased baking dish. Don’t worry about making it perfectly smooth; a rustic look is part of the charm!
Now, sprinkle the corn kernels evenly over the top of the mashed potato layer. The sweetness of the corn will provide a lovely contrast to the savory chicken and rich gravy. After the corn, it’s time for the cheese! Sprinkle the freshly grated cheddar cheese evenly over the corn. Using freshly grated cheese really does make a difference here, as it melts more smoothly and has a better flavor than pre-shredded varieties.
Step 4: The Final Gravy and Bake
We’re almost there! Now, carefully pour the remaining brown gravy over the cheese-covered corn and potato layer. Try to distribute it as evenly as possible, so every bite gets a good amount of that delicious gravy. This will help keep the casserole moist and add another layer of savory goodness.
Finally, if you have any remaining chicken tenders, you can arrange them on top of the casserole for an extra protein boost and a visually appealing finish. This is optional, but highly recommended for extra heartiness! Cover the baking dish loosely with aluminum foil. This will help prevent the cheese from burning too quickly while the casserole heats through.
Step 5: Baking to Perfection
Place the covered casserole dish into your preheated oven. Bake for 20 to 25 minutes. After this initial baking time, remove the aluminum foil and continue to bake for another 10 to 15 minutes, or until the cheese is melted, bubbly, and slightly golden brown, and the casserole is heated through. You’ll want to see some delightful bubbling around the edges.
Allow the casserole to rest for about 5 to 10 minutes before serving. This resting period is crucial; it allows the flavors to meld and the casserole to set slightly, making it easier to serve. When you cut into it, you’ll see distinct layers of creamy mashed potatoes, sweet corn, savory chicken, and gooey cheese, all enveloped in a rich, delicious gravy. Serve hot and enjoy this incredibly satisfying and comforting meal! It pairs wonderfully with a simple green salad or some steamed vegetables.

Frequently Asked Questions:
Can I make this Mashed Potato Casserole ahead of time?
Absolutely! You can assemble the casserole up to a day in advance. Cover it tightly with plastic wrap and refrigerate. When you’re ready to bake, remove it from the refrigerator about 30 minutes before baking to allow it to come closer to room temperature, and then bake as directed, potentially adding a few extra minutes to the cooking time.
What kind of potatoes are best for mashed potato casserole?
For the creamiest and most flavorful mashed potato casserole, I recommend using starchy potatoes like Russets or Yukon Golds. These varieties break down well when boiled and absorb butter and cream beautifully, resulting in a wonderfully smooth and delicious base for your casserole.
