Welcome to your new favorite cozy dinner option: Savory Herb Chicken Casserole. It's packed with tender chicken, vibrant vegetables, and a creamy, cheesy sauce that just might make you forget any other casserole exists. Perfect for those cooler evenings when comfort food is calling your name.
The backbone of this dish is the boneless skinless chicken breasts, providing lean protein and a hearty base. Olive oil helps to brown the chicken, adding a touch of healthy fat. Onions and garlic lay down a fragrant foundation. Carrots and celery bring a subtle sweetness and crunch, while frozen peas add a pop of color and texture.
Chicken broth and heavy cream create a luscious sauce, thickened by all-purpose flour. The herbs, thyme and rosemary, infuse the dish with aromatic warmth. A bit of salt and black pepper round out the flavors. Cheddar cheese offers a savory depth, and cooked rice makes it filling. Finally, breadcrumbs add a crispy, golden topping.
This casserole pairs wonderfully with a simple green salad dressed in a light vinaigrette, which adds a refreshing contrast to the creamy casserole. A side of crusty bread works well to mop up any sauce you might leave behind.
Start by preheating your oven to 375°F (190°C). While it heats, dice your chicken into cubes. In a large skillet over medium-high heat, warm the olive oil. Once shimmering, add the chicken cubes. Let them sizzle away until they're golden brown, about 5 minutes. Remove them with a slotted spoon and set aside.
In the same skillet, toss in the diced onion and minced garlic. Let them sauté until the onion turns translucent. Next, add the carrots, celery, and peas, stirring for another 3 minutes. Sprinkle the flour over the vegetables, stirring continuously for about a minute to cook off the raw taste.
Slowly whisk in the chicken broth and heavy cream, bringing the mixture to a gentle simmer. Stir in the thyme, rosemary, salt, and black pepper. Return the chicken to the pan and let everything simmer together for another 5 minutes.
Take the skillet off the heat and fold in the shredded cheddar and cooked rice. Mix thoroughly to ensure everything is well combined. Pour the mixture into a 9x13 inch baking dish, then sprinkle the breadcrumbs evenly on top.
Bake the casserole in your preheated oven for 25-30 minutes, until it’s bubbly and the top is beautifully golden. Let it cool for about 5 minutes before serving up the goodness!
