Ingredients:
For the Chicken & Mushrooms
2½ lbs chicken breasts, cut into 1-inch strips
1½ tsp sea salt (plus more to taste)
¼ tsp black pepper (plus more to taste)
1 cup all-purpose flour (for dredging)
6 Tbsp olive oil, divided
1 lb white mushrooms, thickly sliced
1 medium onion, finely diced
3 garlic cloves, minced
For the Cream Sauce
3 Tbsp unsalted butter
3 Tbsp all-purpose flour
1½ cups chicken broth
1 Tbsp lemon juice
1 cup half & half (or ½ cup milk + ½ cup heavy cream)
Instructions:
Prepare the Chicken
Preheat oven to 350°F (175°C). Season chicken with sea salt and black pepper. Lightly coat each piece in all-purpose flour.
Sear the Chicken
Heat 3 Tbsp olive oil in a large skillet over medium-high heat. Sear chicken until golden brown (about 4–5 minutes per side). Transfer to a casserole baking dish.
Sauté the Vegetables
In the same skillet, add the remaining olive oil. Cook mushrooms for 5 minutes until browned; remove and set aside. Add diced onion and minced garlic; sauté 2–3 minutes until fragrant.
Make the Creamy Garlic Sauce
Melt butter in the skillet, then whisk in flour to form a roux (1–2 minutes). Slowly pour in chicken broth, whisking constantly. Add lemon juice and half & half. Simmer until thick and creamy.
Combine and Bake
Stir sautéed mushrooms into the sauce and pour over seared chicken in the baking dish. Bake uncovered for 25–30 minutes, until bubbly and the chicken is fully cooked.
Serve
Garnish with fresh parsley or thyme and serve hot with rice, mashed potatoes, pasta, or crusty bread.
Tips & Variations:
Use boneless chicken thighs for extra juiciness.
Add baby spinach or peas for more vegetables.
Try adding grated Parmesan on top before baking for extra cheesy casserole flavor.
