Step-by-Step Instructions

Prepare the Chicken and Sauce:

  1. Preheat the Oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or casserole dish with a little olive oil or cooking spray.
  2. Sear the Chicken: Heat olive oil over medium-high heat in a large skillet. Season both sides of the chicken breasts with salt and pepper, then sear the chicken in the skillet for 2-3 minutes per side, until golden brown. The chicken doesn’t need to be fully cooked at this stage. Remove the chicken from the skillet and set aside.
  3. Sauté the Vegetables: In the same skillet, add the chopped onions and cook for 3-4 minutes until softened. Add the minced garlic and sliced mushrooms, cooking for an additional 4-5 minutes, until the mushrooms release their juices and begin to brown.
  4. Make the Sauce: Stir in the chicken broth, sour cream, thyme, and rosemary. Bring the mixture to a simmer and cook for 2-3 minutes, stirring occasionally to combine all the ingredients into a smooth sauce. Adjust the seasoning with additional salt and pepper to taste.

Assemble the Casserole:

  1. Layer the Ingredients: Place the seared chicken breasts into the prepared casserole dish. Pour the vegetable and sauce mixture over the chicken, making sure the chicken is well-covered.
  2. Top with Cheese: Sprinkle the shredded mozzarella cheese evenly over the top of the casserole. If desired, add grated Parmesan cheese for an extra layer of flavor.

Bake the Casserole:

  1. Bake: Cover the casserole dish with aluminum foil and bake in the preheated oven for 45 minutes. After 45 minutes, remove the foil and bake for an additional 10–15 minutes until the cheese is melted and the chicken is fully cooked (165°F or 74°C internal temperature).
  2. Rest the Casserole: Allow the casserole to rest for 5 minutes before serving so the flavors can settle.

Serve and Enjoy:

  1. Serve: Serve the casserole warm, garnished with fresh parsley if desired. Pair it with a side of vegetables or roasted potatoes for a full meal.

How to Serve

  • With Roasted Vegetables: Serve the casserole alongside a variety of roasted vegetables like carrots, green beans, or broccoli.
  • Over Mashed Potatoes: Pour the creamy casserole over a bed of mashed potatoes for an extra comforting option.
  • With Rice or Quinoa: This casserole is great served with rice, quinoa, or couscous to soak up the flavorful sauce.
  • As a Sandwich: Use the casserole as filling for sandwiches or wraps for a delicious twist.

Additional Tips

  • Ensure Chicken is Seared: Searing the chicken before baking helps retain moisture and adds a nice flavor to the chicken.
  • Use Fresh Herbs: If possible, use fresh thyme and rosemary instead of dried for a brighter, fresher flavor.
  • Add More Veggies: You can easily add vegetables like zucchini, bell peppers, or spinach to the casserole to make it more nutritious and colorful.
  • Lighten it Up: Substitute sour cream with Greek yogurt for a lighter version of the casserole without compromising the creamy texture.
  • Adjust the Cooking Time: If you use bone-in chicken pieces, be sure to adjust the cooking time and check that the internal temperature reaches 165°F (74°C).

Recipe Variations

  1. Cheesy Chicken Casserole: Add a layer of shredded cheddar cheese on top before baking for extra cheese flavor.
  2. Ranch Chicken Casserole: Mix in a packet of ranch seasoning with the sour cream for a tangy, flavorful twist.
  3. Gluten-Free Casserole: Use gluten-free breadcrumbs or cornstarch for a gluten-free alternative to flour-based roux.
  4. Chicken Casserole with Bacon: Add crispy cooked bacon on top for an added smoky flavor that pairs beautifully with the creamy chicken.
  5. Spicy Chicken Casserole: Add chili flakes or jalapeños to the sauce for some heat.
  6. Veggie-Packed Casserole: Stir in extra veggies like peas, carrots, and corn to make this casserole even heartier.

Freezing and Storage

  • Storage: Leftover casserole can be stored in an airtight container in the refrigerator for up to 3–4 days.
  • Freezing: This casserole can be frozen for up to 3 months. Cool completely before wrapping and freezing in a freezer-safe container. Thaw in the refrigerator overnight and reheat in the oven at 350°F (175°C) until heated through.

Special Equipment

  • Baking Dish: A 9×13-inch baking dish is perfect for this casserole recipe, allowing for even cooking.
  • Skillet: Use a large skillet to sear the chicken and sauté the vegetables and sauce before baking.
