Ingredients
Makes one 9×13-inch casserole (6–8 servings)
- 3 cups cooked, shredded chicken (rotisserie or oven-roasted)
- 2 tablespoons olive oil or butter
- 1 medium onion, diced
- 2 cloves garlic, minced
- 2 cups mushrooms, sliced (optional)
- 2 cups mixed seasonal vegetables (carrots, diced squash, or green beans)
- 1 teaspoon dried thyme
- 1/2 teaspoon smoked paprika
- Salt and pepper, to taste
- 3 tablespoons all-purpose flour
- 1 3/4 cups low-sodium chicken broth
- 1 cup milk or a creamy non-dairy alternative
- 1 cup shredded cheddar or a melty cheese blend
- 2 cups cooked rice, pasta, or cubed potatoes
- 1/2 cup plain breadcrumbs or crushed crackers for topping
- 2 tablespoons chopped fresh parsley for garnish
Step-by-step instructions
- Preheat and prep: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with a little butter or oil.
- Sauté aromatics: In a large skillet over medium heat, warm the olive oil, then add diced onion and cook until translucent (about 4–5 minutes). Add garlic and mushrooms; cook another 2–3 minutes.
- Build the sauce: Sprinkle the flour over the vegetables and stir for 1 minute to cook the raw flavor out. Gradually whisk in chicken broth and milk until smooth. Stir in thyme, paprika, and season with salt and pepper. Let the sauce simmer until it thickens slightly, about 3–4 minutes.
- Combine casserole: Remove from heat and stir in shredded chicken, cooked rice (or pasta/potatoes), mixed vegetables, and half the cheese. Taste and adjust seasoning.
- Assemble and top: Transfer the mixture to the prepared baking dish. Sprinkle the remaining cheese and breadcrumbs evenly over the top. For extra crunch, dot the top with small pieces of butter.
- Bake: Place the dish in the oven and bake for 20–25 minutes, until bubbly and golden. If the top browns too quickly, tent loosely with foil.
- Rest and serve: Let the Chicken Casserole rest for 5–10 minutes before serving. Garnish with fresh parsley and serve warm.
Tips for success
- Use well-seasoned chicken: Rotisserie chicken is a fast shortcut and adds a deep flavor. If you roast chicken yourself, save the pan juices for extra richness.
- Don’t overcook starch: If you use pasta, cook it slightly less than al dente because it will continue cooking in the oven.
- Make it creamy without curdling: Use room-temperature milk and add it slowly while whisking to keep the sauce smooth.
- Add texture: Stirring in a handful of toasted nuts or swapping breadcrumbs for a buttery streusel topping will create a lovely contrast.
- Beginner-friendly technique: If your sauce is thin, mix 1 teaspoon cornstarch with 1 tablespoon cold water and stir into the simmering sauce until it thickens.
Possible variations
- Gluten-free: Replace all-purpose flour with a gluten-free flour blend, and use gluten-free breadcrumbs or crushed GF crackers for the topping. This keeps the flavors intact while accommodating dietary needs.
- Streusel topping: For a sweet-savory crunch, mix 1/2 cup panko or breadcrumbs with 2 tablespoons cold butter, 1 tablespoon brown sugar, and a pinch of salt; sprinkle over the casserole before baking.
- Cheesy herb: Swap cheddar for Gruyère and add a teaspoon of fresh thyme and rosemary for a more aromatic finish.
- Lighter version: Use Greek yogurt instead of half the cheese and choose low-fat milk to cut calories without sacrificing creaminess.
- Flavor swaps: Try stirring in a spoonful of Dijon mustard, a splash of white wine, or a handful of roasted peppers for new depth—see how different family favorites compare at this roundup of hearty recipes like our own best chicken casserole recipes.
Storage recommendations
- Refrigerate: Cool the casserole to room temperature, cover tightly, and refrigerate for up to 3–4 days.
- Reheat: Reheat individual portions in the microwave or warm the whole casserole in a 350°F (175°C) oven for 15–20 minutes until heated through.
- Freeze: For longer storage, freeze individual portions or the whole dish (well-wrapped) for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Refresh after storage: If the casserole seems dry after reheating, stir in a splash of broth or milk and cover with foil while warming to retain moisture.
