Creamy Chicken Casserole Recipe

This creamy chicken casserole with mushrooms (known to some as “Chicken Gloria”), will win you over. This chicken bake is the PERFECT party dish and is a reader favorite on our blog.

The chicken in this chicken casserole is incredibly tender - you will savor every morsel! This chicken bake re-heats really well (if you are lucky enough to have leftovers).

Ingredients
Ingredients for Chicken and Mushroom Casserole:

• 2 1/2 lbs chicken breasts (4 to 5 large), cut into 1 -inch thick strips
• 1 1/2 tsp sea salt plus more to taste
• 1/4 tsp black pepper plus more to taste
• 1 cup all-purpose flour to coat the chicken
• 6 Tbsp olive oil divided
• 1 pound white mushrooms thickly sliced
• 1 medium onion finely diced
• 3 garlic cloves minced
• Ingredients for the Sauce:
• 3 Tbsp unsalted butter
• 3 Tbsp all-purpose flour for the sauce
• 1 1/2 cups chicken broth
• 1 Tbsp lemon juice
• 1 cup half and half or 1/2 cup milk + 1/2 cup heavy cream
• US Customary - Metric

Instructions

1. Season chicken with salt and pepper and dredge both sides in flour. Heat 3 Tbsp oil in a large skillet over medium/high heat. Once oil is hot, add chicken and saute until golden. Work in batches if needed so you don't crowd your pan. Don't worry about cooking the chicken through; it still needs to go in the oven. Transfer chicken to a 13x9 casserole baking dish.
2. Scrape of any debris from the skillet. Add 3 Tbsp oil along with sliced mushrooms and diced onions and saute until soft and golden. Add garlic and saute another 1-2 min. Spread mixture over the chicken.
3. In a medium saucepan (or in the same pan you've been using), melt 3 Tbsp butter. Whisk in 3 Tbsp flour until lightly golden (1-2 min).
4. Add 1 1/2 cups chicken broth, 1 Tbsp lemon juice, 1/4 tsp pepper, and whisk until smooth. Add 1 cup half & half and bring to a simmer. Season with salt and pepper to taste.
5. Pour sauce over the chicken and mushrooms. Cover with foil and bake at 350˚F for 45 minutes. Serve warm or hot over mashed potatoes, pasta or rice.

Recipe Notes

Don't use a dutch oven for this recipe, it just doesn't turn out right - I'm not sure why. You can add artichoke to this, but don't try zucchini (turns to mush).
