Key Ingredients for Success
The secret to an extraordinary casserole lies in high-quality ingredients and proper preparation. Let’s break down what you’ll need.
1. Chicken
- Use boneless, skinless chicken breasts or thighs for tenderness.
- For extra flavor, marinate in olive oil, garlic, and herbs before cooking.
- Cook until golden for that signature crispy texture.
2. Potatoes
- Russet or Yukon Gold potatoes are ideal for mashing due to their starchy texture.
- Always peel and chop evenly to ensure even cooking.
3. Butter
- Unsalted butter allows you to control salt levels.
- Adds richness and creaminess to the mashed potatoes.
4. Sour Cream
- Gives the potatoes a smooth, tangy depth of flavor.
- Can be substituted with Greek yogurt for a lighter twist.
5. Cheese
- Sharp cheddar offers bold flavor.
- A blend of cheddar, mozzarella, and Parmesan creates a perfect melt.
6. Breadcrumb Topping
- Panko breadcrumbs create the crunchiest topping.
- Combine with melted butter for an even golden crust.
