Recipe Background

Enjoy the rich blend of chicken and mushrooms in a creamy, tangy sauce.
There's something immensely comforting about a well-made chicken casserole. The aroma wafting through the kitchen brings back memories of family dinners and shared laughter. This casserole combines the earthy richness of mushrooms with tender chicken strips, all enveloped in a creamy sauce. As you cook, the scent of garlic mingles with the golden mushrooms, creating a nutty, warm fragrance that fills the room. Dropping a touch of lemon juice at the end adds just the right brightness, cutting through the creaminess with subtle zing.
Texture is key in this dish, from the softness of the sautéed onions to the slight crisp of seared chicken. Browning the chicken strips until their edges deepen enhances flavor and adds a pleasing contrast once they're baked in the sauce. The final casserole emerges from the oven bubbling gently, topped with a sprinkle of fresh parsley. This pop of green atop the creamy layer is not just a visual delight—it also adds a fresh bite with each serving.
Gathering around the table with this casserole is a simple joy. The warmth spreads from the dish to those enjoying it, creating connections over shared plates. Whether it's a weeknight comfort or a dish for guests, this recipe offers not just sustenance but a touch of culinary magic. It's a meal crafted with both heart and taste, encouraging slow moments of togetherness.

Ingredients

For the casserole:

  • 2 1/2 pounds chicken breasts boneless and skinless, cut into 1-inch-thick strips
  • 1 1/2 teaspoons sea salt
  • 1/4 teaspoon black pepper
  • 1 cup all-purpose flour
  • 6 tablespoons olive oil divided
  • 1 (16-ounce) package white mushrooms thickly sliced
  • 1 medium onion finely diced
  • 3 cloves garlic minced

For the sauce:

  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 1 1/2 cups chicken broth
  • 1 tablespoon lemon juice
  • black pepper to taste
  • 1 cup half-and-half
  • table salt to taste
  • fresh parsley leaves optional, to taste, for garnish

Directions

  • Preheat the oven to 350 degrees F.
  • Season the chicken strips with 1 1/2 teaspoons of the sea salt and 1/4 teaspoon of the black pepper.
  • Dredge the chicken strips in 1 cup of the all-purpose flour until well-coated.
  • In a large skillet over medium-high heat, add 3 tablespoons of the oil.
  • Add the dredged chicken strips and cook, while stirring, until they are golden but not quite cooked through, about 3 minutes. You may need to cook the chicken strips in batches to avoid overcrowding.
  • Transfer the chicken strips to a 9x13-inch baking dish.
  • Scrape the browned bits from the skillet, then over medium-high heat, add the remaining oil.
  • Add the mushrooms and the onions to the hot oil and cook, while stirring, until soft and golden, about 4-5 minutes.
  • Add the garlic to the mushroom mixture and cook, while stirring, until fragrant, about 1-2 minutes.
  • Spread the mushroom mixture over the chicken strips in the baking dish.
  • In the same skillet over medium heat, melt the butter.
  • Add the remaining flour to the butter and cook, while stirring, until the flour is lightly golden, about 1-2 minutes.
  • Add the chicken broth, the lemon juice, and the extra black pepper to the butter mixture and whisk until a smooth sauce forms.
  • Add the half-and-half to the sauce and bring it to a simmer.
  • Season the sauce generously with the extra table salt and the extra black pepper.
  • Pour the sauce mixture over the chicken strips and the mushroom mixture in the dish.
  • Cover the baking dish with foil and bake until the chicken strips reach an internal temperature of 165 degrees F, about 45 minutes.
  • Serve hot garnished with the parsley leaves.
