A comforting and flavorful casserole combining layers of cheesy potatoes, noodles, and sautéed onions.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated for even cooking.
Peel and boil the potatoes in a large pot of salted water until tender, then mash them with a portion of butter, salt, and pepper.
For creamier potatoes, add a splash of milk or cream while mashing.
Cook the egg noodles according to the package instructions, then drain and set aside.
Avoid overcooking the noodles to maintain their texture.
Sauté the onions in the remaining butter in a skillet until soft and translucent, seasoning with salt and pepper.
Cook the onions on medium heat to prevent burning.
Spray a 9x13 casserole dish with non-stick spray. Layer half of the noodles, followed by half of the mashed potatoes, half of the sautéed onions, and half of the shredded cheese. Repeat the layers.
Press each layer gently to ensure even distribution.
Cover the dish with foil and bake in the preheated oven for 30 minutes.
Covering with foil helps retain moisture during baking.
Remove from the oven, let it cool slightly, and serve warm.
Garnish with fresh parsley for a pop of color and flavor.
