- Onion – 1 medium yellow onion, diced
- Garlic – 3 cloves, minced
- Olive oil – 2 tablespoons (or another cooking oil)
- Dried thyme – 1 teaspoon
- Salt and black pepper – to taste
- Cream of chicken soup – 1 (10.5 ounce) can (or cream of mushroom/celery)
- Milk – 1 cup (whole milk recommended for richness)
- Sour cream – 1 cup (regular sour cream or Greek yogurt for a lighter option)
- Colby Jack cheese – 2 cups shredded (cheddar or Monterey Jack are good alternatives)
- Fresh parsley – chopped, optional garnish
Substitutions & variations: Swap in sweet potatoes for a slightly sweeter flavor (adjust cooking time). Add cooked crumbled bacon for a richer, loaded version. Fresh herbs like rosemary or parsley brighten the dish. Use a different cheese for varied melt and flavor.
How to make chicken potato casserole
STEP ONE – Preheat the oven to 375°F (190°C). Grease a 9×13 inch (23×33 cm) baking dish.
STEP TWO – Heat olive oil in a large skillet over medium heat. Add the diced onion and minced garlic and sauté until softened, about 5 minutes. Cooking them first brings out their sweetness and prevents a raw onion taste.
STEP THREE – Add the shredded chicken to the skillet and season with dried thyme, salt, and pepper. Cook 2–3 minutes to marry the flavors.
STEP FOUR – In a large bowl, whisk together the cream of chicken soup, milk and sour cream until smooth.
STEP FIVE – Layer the cubed potatoes in the prepared baking dish. Spoon the chicken-onion mixture over the potatoes, then pour the soup mixture evenly across the top. Scatter the mixed vegetables and gently stir to incorporate everything so the sauce coats the potatoes and chicken.
STEP SIX – Cover the dish tightly with foil and bake for 35–40 minutes, until the potatoes begin to soften.
STEP SEVEN – Remove the foil and sprinkle the shredded Colby Jack cheese across the top.
STEP EIGHT – Return the casserole to the oven and bake uncovered for another 15–20 minutes, until the potatoes are tender throughout and the cheese is melted and lightly golden.
STEP NINE – Let the casserole rest for about 10 minutes before serving to allow the sauce to set slightly.
Can I make this casserole ahead of time?
Yes. Assemble the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours. When baking from chilled, add about 10–15 minutes to the covered baking time to ensure the potatoes cook through.
Storage and reheating instructions
Store leftovers in an airtight container in the refrigerator for up to 3 days.
Freezing is not ideal because potatoes can turn mushy after thawing, but if needed freeze in a suitable container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheat in a 350°F (175°C) oven until warm, or reheat individual portions in the microwave in 30-second intervals until heated through.
