Introduction

This Cheesy Chicken and Potato Casserole is a comforting and rich dish perfect for a family meal. Creamy, flavorful, and loaded with gooey cheese, it combines tender chicken, hearty potatoes, and a touch of spice for a satisfying feast.

A white rectangular dish holds a baked casserole with two main layers visible: the bottom layer is creamy and rich, covered fully by a golden-brown melted cheese layer that is bubbly and slightly crispy around the edges. Small specks of fresh green herbs, likely parsley, are scattered evenly over the top, adding a fresh pop of color. The dish is placed on a soft gray cloth with a blurred green garnish bowl in the background, all set on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

4 tbsp butter
4 tbsp flour

3 cups milk
½ cup minced onions

2-4 count minced green chilies
1 – 1 ½ cups cut up boiled potato

¾-1 cup sweet corn
1 – 1 ½ cups shredded chicken
1 cup chicken stock

Pinch of grated nutmeg (optional)
½ tsp black pepper
Salt, to taste

2 ½ cups shredded cheese

Instructions

Step 1: Lightly grease a 10-cup baking dish and preheat your oven to 400°F (200°C).
Step 2: In a large pot or Dutch oven, melt the butter over medium heat. Sprinkle in the flour and stir constantly for about 2 minutes.

Step 3: Gradually pour in the milk while whisking to create a smooth sauce without lumps. Keep stirring as the mixture thickens and bubbles.
Step 4: Add the minced onions, green chilies, nutmeg (if using), black pepper, and chicken stock. Cook for another 3-5 minutes while stirring.
Step 5: Remove the sauce from heat and gently fold in the shredded chicken, boiled potatoes, and sweet corn.

Step 6: Stir in 1 ½ cups of shredded cheese. If the sauce is too thick, add a little reserved milk to loosen it.
Step 7: Taste and season with salt as needed. Pour the mixture into the prepared baking dish.
Step 8: Scatter the remaining cheese over the top. Bake for 8-10 minutes, then broil for 2 minutes until the cheese is golden and bubbly.

Tips & Variations

Use mild or spicy green chilies depending on your heat preference.
Swap sweet corn with frozen peas or mixed vegetables for a different texture and flavor.
For extra creaminess, stir in a dollop of sour cream or cream cheese before baking.

Make it ahead by preparing the sauce and assembling the casserole, then refrigerate until ready to bake.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through, about 15-20 minutes, or microwave individual portions until hot.
