Step-by-Step Instructions

  1. Preheat the oven: Set a rack in the center of the oven and preheat to 350°F (177°C). Lightly grease a 2-quart casserole dish with nonstick cooking spray and set it aside.

  2. Sauté the vegetables: In a large skillet, add ½ tablespoon of olive oil and heat over medium-high until shimmering. Add the diced bell pepper, onion, and celery, cooking until softened, about 5 minutes. Add the minced garlic and cook until fragrant, about 1 minute. Remove from heat.

  3. Combine the filling: Transfer half of the vegetable mixture to the prepared casserole dish. In a mixing bowl, combine the remaining vegetables with shredded chicken, cream of mushroom soup, sour cream, water, and ½ teaspoon of black pepper. Stir until well mixed, then transfer to the casserole dish.

  4. Prepare the topping: In a small mixing bowl, combine the crushed corn flakes, smoked paprika, the remaining ½ tablespoon of olive oil, and the remaining ½ teaspoon of black pepper. Stir until the corn flakes are coated, then sprinkle evenly over the casserole mixture.

  5. Bake: Place in the oven and bake for 25 minutes. Afterward, remove it from the oven and lightly spray the cornflake topping with nonstick cooking spray. Return to the oven and bake for another 5 minutes until golden brown and bubbly.

  6. Rest and serve: Once baked, let the casserole rest for 5 to 10 minutes before serving. Enjoy!

Best Ways to Enjoy It

This Heart Healthy Chicken Casserole is delicious on its own, but you can elevate the experience by pairing it with a simple side salad for a crisp contrast. A light cucumber salad or steamed broccoli would complement it beautifully. For a comforting touch, consider serving it with whole-grain bread to soak up any creamy goodness.

Keeping Leftovers Fresh

To store your leftovers, transfer the casserole to an airtight container once cooled. It can be refrigerated for up to 3 days. If you want to keep it longer, consider freezing individual portions. To reheat, simply microwave until heated through or bake in the oven for a fresh finish.

Creative Twists to Try

Feel adventurous? You could add diced mushrooms or spinach to the filling for extra nutrition. Alternatively, switch out the topping for crushed tortilla chips for a different crunch. The possibilities are endless with this base recipe!

Your Questions Answered

Can I use other vegetables?

Absolutely! Carrots, peas, or even spinach can work well in this recipe.

Is it okay to use canned chicken?

Yes, canned chicken can save time, but fresh or rotisserie chicken will yield better flavor and texture.

How do I make it dairy-free?

Substitute the sour cream with a dairy-free alternative, such as coconut yogurt, and use a dairy-free cream soup.
