Ingredients
- 3 cups cooked chicken breast, shredded or diced
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 large yellow onion, diced (about 1 cup)
- 2 medium carrots, peeled and diced (about 1 cup)
- 2 celery stalks, diced (about 3/4 cup)
- 3 cloves garlic, minced
- 1 cup frozen peas
- 1 cup frozen corn
- 1/4 cup all-purpose flour
- 2 cups low-sodium chicken broth
- 1 cup whole milk (or half-and-half for extra richness)
- 1/2 teaspoon dried thyme
- 1/2 teaspoon dried parsley
- 1/4 teaspoon ground black pepper
- 3/4 teaspoon kosher salt (plus more to taste)
- 1 tablespoon Worcestershire sauce
- 1 tablespoon lemon juice (freshly squeezed)
- 1 cup shredded sharp cheddar cheese
- 1/2 cup sour cream
- 1 cup panko breadcrumbs
- 2 tablespoons melted butter (for topping)
- 2 tablespoons chopped fresh parsley (for garnish, optional)
Instructions
- Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch casserole dish or a similar 3-quart baking dish.
- In a large skillet or Dutch oven, melt 2 tablespoons butter with 1 tablespoon olive oil over medium heat. Add diced onion, carrots, and celery. Sauté for 5-7 minutes, until vegetables are softened but not browned.
- Add minced garlic and cook for 1 minute, stirring frequently until fragrant.
- Sprinkle the flour over the vegetables, stirring constantly for 2 minutes to form a roux and cook off the raw flour taste.
- Gradually whisk in the chicken broth, then the milk, stirring well to prevent lumps. Bring to a gentle simmer, stirring frequently, until the sauce thickens, about 4-5 minutes.
- Stir in thyme, parsley, black pepper, salt, Worcestershire sauce, and lemon juice. Taste and adjust seasoning if needed.
- Add the shredded chicken, frozen peas, and frozen corn. Stir to combine and heat through for 2-3 minutes.
- Remove from heat. Stir in the shredded cheddar cheese and sour cream until smooth and creamy.
- Pour the chicken mixture into the prepared casserole dish, spreading it evenly.
- In a small bowl, toss the panko breadcrumbs with 2 tablespoons melted butter until evenly coated. Sprinkle the breadcrumb mixture evenly over the casserole.
- Bake uncovered for 20-25 minutes, or until the topping is golden brown and the filling is bubbling at the edges.
- Remove from oven and let rest for 10 minutes before serving. Garnish with fresh chopped parsley if desired.
Tips
- Chicken Options: Rotisserie chicken, leftover roast chicken, or poached chicken breasts all work well. For extra flavor, use a mix of white and dark meat.
- Vegetable Swaps: Substitute or add other vegetables like diced potatoes, green beans, or mushrooms. Sauté mushrooms with the onions for best flavor.
- Gluten-Free: Use a gluten-free flour blend for the roux and gluten-free breadcrumbs for the topping.
- Make Ahead: Prepare the filling and topping separately, refrigerate up to 2 days, then assemble and bake when ready to serve. Add 5-10 minutes to baking time if baking straight from the fridge.
Serving Suggestions
This casserole is a one-dish meal, but you can round it out with a crisp green salad tossed in a tangy vinaigrette to balance the richness. Warm, crusty bread or homemade biscuits are perfect for scooping up the creamy filling. For a lighter side, serve with steamed green beans, roasted Brussels sprouts, or sautéed spinach. A simple fruit salad also makes a refreshing finish.
Variations
- Turkey Pot Pie Casserole: Substitute the chicken with cooked turkey for a great post-holiday leftover dish.
- Vegetarian Version: Omit the chicken and add more vegetables (such as mushrooms, cauliflower, or broccoli). Use vegetable broth instead of chicken broth.
- Crust Topping: For a traditional touch, top with puff pastry or pie dough instead of breadcrumbs. Lay over the filling, brush with egg wash, and bake as directed.
- Spicy Kick: Add 1/2 teaspoon crushed red pepper flakes or a diced jalapeño to the sautéed vegetables for some heat.
- Cheese Lovers: Mix in a blend of cheeses, such as Gruyère or Monterey Jack, for extra depth and creaminess.
Storage and Reheating
Let leftovers cool to room temperature before covering tightly with foil or transferring to airtight containers. Store in the refrigerator for up to 4 days. For longer storage, freeze individual portions in freezer-safe containers for up to 2 months. To reheat, cover and bake in a 350°F (175°C) oven for 20-25 minutes, or until hot throughout. If reheating from frozen, thaw overnight in the fridge, then reheat as above. You can also microwave individual portions for 2-3 minutes, stirring halfway, but the topping will be less crisp.
Frequently Asked Questions
- Can I make this recipe ahead of time?
Yes! Prepare the filling and topping separately, refrigerate both for up to 2 days, then assemble and bake when ready. If baking straight from the fridge, add 5-10 minutes to the baking time to ensure the center is heated through. - What’s the best way to cook chicken for this recipe?
Poaching boneless, skinless chicken breasts or thighs in simmering broth yields moist, tender meat. Alternatively, shred a store-bought rotisserie chicken to save time. Just avoid overcooking, as dry chicken can make the casserole less creamy. - Can I use fresh vegetables instead of frozen?
Absolutely. Fresh peas and corn work well; simply add them to the skillet with the carrots and celery to soften slightly before adding the liquids. Adjust cooking time as needed for firmer vegetables. - How do I keep the topping crispy when reheating?
For the crispiest results, reheat leftovers in the oven uncovered. If microwaving, the topping will soften, but you can revive it by broiling for 2-3 minutes after reheating. - Is this recipe freezer-friendly?
Yes, the casserole freezes well. Cool completely, wrap tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating for best texture. - Can I use a different cheese?
Yes, feel free to experiment with your favorite cheeses. Mild cheddar, Gruyère, Monterey Jack, or a blend all work nicely. Just make sure the cheese melts smoothly for the creamiest filling.
